“Hey, can you re-freeze this ice pack?” Sentry asked, holding out the jiggling plastic in front of your view of the television. His broad frame casted shadows over the couch you were laying on, the sheer width of his shoulders covering the low light of the Watchtower’s lounge, causing everything to look darker to you suddenly. He kept his voice low, almost hesitant in his delivery because the last thing he wanted to do was inconvenience you and pull you from the nest of blankets you had burrowed yourself into after you had eaten dinner.
A small hum escaped your throat, slipping one hand free from your heavy coverings, the chill of your own skin already raising an array of goosebumps along your arm, before pressing your small palm to the bag. The liquid inside stiffened instantly beneath your touch, frost racing across the plastic in delicate, branching veins until the whole thing hardened into a solid, icy block.
“Thank you,” Sentry murmured, drawing the pack back quickly, as a few droplets slipped from the plastic and landed on your blankets, darkening the fabric in tiny, perfect circles before they could soak through the layers you had over your body.
“Who needs the ice pack?” You questioned, bringing your arm back under the confines of your coverings and nuzzling yourself deeper into them, chasing the illusion of warmth even though you knew it was pointless–because every shift of your body only caused another burst of cool air to envelop you, putting you right back to square one.
“Me. I’m boiling hot and it feels like I’m coming down with the flu or something…” He explained, pressing the newly frozen pack to the side of his neck. The mentioning of his overheating drew your gaze upward, before you shifted your body toward him to get a better view.
His normally pale skin had flushed a deep, splotchy red, the colour rising high across his cheekbones and spreading down the strong column of his throat before disappearing beneath his shirt. A faint sheen of sweat glistened at his hairline, dampening the wavy light brown strands that fell across his forehead, making them curl at the ends as if he had just gotten out of the shower. The soft fabric of his t-shirt clung in patches to the solid planes of his chest, outlining the heavy muscle beneath, so much so, that you could practically count every single ridge of his abs that were on display to you.
Even standing still he looked imposing–broad through the shoulders, arms thick with pale blue veins that pulsed over the muscles as if the rapid beating of his heart had ignited the blood that flowed through them–yet the way he was holding himself was not the typical form Sentry often took when he presented his body to onlookers. It was like he was embarrassed of the uncontrollable heat that was rolling off of him–and embarrassment didn’t look good on a sun God.
“Mmm…I don’t think it’s the flu, Sentry.” You stated, your teeth clattering together as a violent shiver tore through you. The cold sank deeper into your bones, contracting every muscle before you forced yourself to breath through it–even though it was like your heart had seized inside your chest. He frowned at your comment, patting the ice pack slowly down the length of his neck.
“Then what the hell is it? ‘Cause I feel like I’m on the verge of setting this whole place on fire.” He huffed, lifting his free hand to fan himself rapidly, hoping that it would aid in cooling him down. The gesture did nothing but stir the humid air around him though, and he felt fresh beads of sweat breaking out along his skin, sliding down his neck and lower back, creating an inescapable dampness over his entirety. He wanted to rip his clothes off in those moments, because modesty wasn’t going to cure whatever was happening to him, but out of respect for you, he held himself back from becoming a free form tornado of fabric.
“You’re having a temperature crisis…It’s normal for people like us.” You informed, watching the confusion deepen between his brows, seeing wrinkles appear between them.
“Temperature crisis?” He questioned, his golden eyes narrowing slightly as he studied you, thinking you were lying to him to make him feel better, but you gave him a small, stiff nod.
“It’s when your body can’t handle the excess energy it takes to constrict your powers, so it just gives up and lets them spiral out of control. It takes a bit of time to recalibrate, but you’ll be back to normal in a few days.” He let out a long, exhausted sigh, rubbing his forehead roughly, as a few damp strands of hair fell forward to frame his face, tickling the sharp line of his jaw. The ice pack was already softening again, feeling the condensation beginning to bead along the plastic, hissing where it touched his overheated skin and dissolved. You were surprised the encasement didn’t melt in his hands, but you didn’t question it.
“There’s no way to speed up this whole recalibrating process?” He pressed, and you shrugged, tugging the blankets higher until they rested just beneath your chin, even though they were useless at this point.
“I haven’t found a solution myself, and I’ve been through hundreds of these…So I’d say your case wouldn’t be any different to mine.” You replied, the words leaving your lips in a faint cloud of breath as another chill surged through your body. Your muscles quivered deep beneath the layers of fabric, a full-body tremor that started in your core and radiated outward until even your fingertips felt numb. Your heart skipped–a sharp, irregular contraction that made you feel like your blood had stopped flowing through your veins, like frozen pipes–before it steadied again into the strained rhythm it had been fighting to keep all evening.
Sentry watched it happen, observing the way your eyes clenched shut for a single moment, the loud clatter of your teeth cutting through the quiet living space, and how you burrowed even deeper beneath the coverings until only the top of your head and the narrow strip of your eyes remained visible above the blanket’s edge. You looked impossibly small against the wide couch, swallowed whole by the cluster of covers–if he wasn’t actively speaking to you he would’ve mistaken you for the couch cushions, and he was thankful he didn’t accidentally sit on you in the heated haze he was in.
But then it all the puzzle pieces seemed to click into place from these simple little things you had done…You were going through your own temperature crisis right now, just like him.
Evidently the two of you had synced up in some inexplicable way–likely from the string of back-to-back mission that had drained your respective reserves at similar paces. You were so used to this cycle you had come to expect it and endured it like normal, but Sentry evidently had a larger power bank than you, and with that came a far more intense reaction. Where you accepted the inevitable discomfort with grim resignation, he looked like he wasn’t going to sit with it and do the same, and you could see the impatience in his glowing eyes–the way they shifted around the room as if he was searching for a physical solution to his problem.
“So what do you do to cope with this whole thing then?” He asked, stepping closer to the couch, hearing the floor panels beneath his weight creak in a soft protest, pressing the icepack to the side of his neck again. The frozen block had already surrendered to the heat, reduced to nothing more than a lukewarm liquid that sloshed inside the thin plastic again just like before–putting him right back to the situation he had been in when he approached you just moments ago. Stray droplets slid across his heated skin and rose instantly in faint threads of steam, vanishing into the air and catching the light for a brief moment.
There was a pang of jealousy that sliced through you in those moments–to be that hot right now would have been everything, a fevered dream of warmth you would have given anything to claim because the frigid cold that overtook your entirety was absolutely miserable. Your eyes lifted toward him, and the same feelings were mirrored by him, etched into the way his gaze lingered on the thin rim of frost that was spreading along the blanket’s edge, each heavy breath you exhaled feeding the delicate crystals that clung to the fabric and expanded along it.
“I just su-suffer,” You stuttered, drawing your knees up to your chest, hoping the shift in position would spark even the smallest pocket of warmth against your skin, though your past experiences had already taught you the futility of it–the pessimist in you was on full display tonight.
A short laugh escaped Sentry, dragging one of his large hands through his hair, pushing the wavy brown locks back from his forehead only for them to tumble forward again in a heavier, more disheveled sweep that stuck to the sweat at his temples. The sound carried no mockery, only the shared frustration threaded with reluctant amusement and a faint hint of disbelief that the two of you had somehow collided in the same miserable state.
As much as the two of you existed as literal opposites in temperature, you had always found a solid ground when you worked together. You liked how straightforward he became once his walls had come down, how the sheer scale of his presence never crowded the mission once he let you set the pace–how he let you lead rather than follow his orders.
He stayed out of your way and you stayed out of his, and when the moment demanded it and the two of you had to stand shoulder to shoulder, you allowed instinct to take over–adjusting into an effortless rhythm where fire and ice moved in perfect tandem, as though the choreography had been drilled into muscle memory long before either of you truly realized it.
Being locked in this crisis together felt entirely different. There was no tactical formation to fall back on, and no clear objective to chase down and eliminate. And that absence of control was exactly what gnawed at Sentry now. He knew there was a solution; he could practically feel it radiating off your bundled form even from the distance that he kept, and he hated to admit it–but he craved it.
The only question was whether you would agree to it, to the exchange, and he found himself weighing the idea in silence, deciding that the risk would be worth taking if it meant ending this torment faster.
“Well…Maybe we could try something that might solve our issues, since it seems like you’re also going through one of your own crises right now.” He said, watching as your eyebrows raised at the tone of his voice–at the soft hesitance that laced every word, like the suggestion that was pressing down on his tongue was going to jump out at any second and display itself to you. In the few seconds of silence you ran through the only two possibilities that made sense in a situation like this, and both of them circled an intimacy line neither of you had crossed together. Still, you found yourself nodding for him to go on.
When he didn’t continue immediately, you cleared the dryness in your throat.
“Let’s hear it,” You urged, because at this point you were willing to entertain any idea that might recalibrate your system before the shivers escalated into something far worse and far more unmanageable.
“We both have something that the other one needs–you have to get warmed up, and I need to cool down.” He trailed off, his eyes locking onto yours like he was pleading for you to finish the thought and offer up the idea yourself so he wouldn’t have to do it. You could sense the hesitation in his voice and it sat strangely on him–almost boyish, like his typical over confidence had plummeted, knowing that there was a chance of being outright rejected. When he saw the patient blankness in your gaze though, he continued “So why don’t we try using each other for that?”
For a split second your eyes widened at the way he phrased things. Using each other sounded so…Cold and transactional. And you both knew that it wasn’t going to be anything like that, especially depending on how he decided to approach this solution. There wasn’t any harm in entertaining it, you trusted him with your life during every mission the two of you were sent together on, so trusting him with your body–and with your powers–felt like the next logical step.
You could see him bracing for your reply, as if he were already preparing for the sting of rejection. But when you shifted beneath the heavy nest of blankets and eased your head out a little further–enough for the low lounge lights to catch the relaxed lines of your face and the frost that began to glimmer along your lashes–he knew. The tension in his jaw eased, and the golden hue of his eyes softened, turning just a fraction brighter before dimming to a sweet caramel colour.
“Let’s try it…Wh-What’s the worst that can happen?” You questioned, hearing him let out a huff of a laugh.
“Mmm, maybe you shouldn’t say that…Those are famous last words.” He commented, seeing you shrug, the movement stiff from the cold that was continuing to stiffen your muscles.
“It’s true though, is it not?” He hummed in quiet agreement, tossing the melted ice pack onto the side table near the couch with a thud. The discarded bag landed with a faint slosh, already forgotten as he stepped closer to your lying form.
“I guess…” He mumbled, pausing to look down at you, letting his golden eyes trace the bundled shape of your body before lifting to your face. Even from this nearness you could feel the heat radiating off him in thick waves–almost like a invisible force–pressing against the chilled air around you as it expanded outward from his flesh.
When you drew in a slow breath, the scent of him filled your lungs–smoky and metallic, like overheated wiring that was under strain, yet undercut by something oddly comforting, as if he was a fresh bonfire.
“So how are we going to do this?” You asked, watching as his gaze dropped to the thick pile of blankets still covering you. His fingers twitched against the hem of his top, toying with the stitches.
“We’ll take off our clothes so that we can have skin to skin contact…It’ll speed up the process, so we won’t have to be against one another for too long.” You felt your stomach drop to your feet at that, a deep pang of worry blooming hot through your nerves despite the cold that was locked in your blood. He sensed it immediately–the slight hitch in your breathing, the way your fingers tightened around the edge of the blanket–but he didn’t push. His phrasing had landed poorly again, yet you understood the intent behind it, and after a beat you accepted the practicality of the plan.
“Alright,” You replied, giving him a small nod as you began to shift beneath the blankets. Your hands found the hem of your sweater, tugging it upward, the heavy knit catching briefly on your elbows before you pulled it free and tossed it onto the ground. Three long-sleeved shirts followed, then a plain t-shirt, and finally a thick tank top, the frost along the material melting and creating small puddles of water on the wooden floors.
Sentry’s eyes widened a fraction with every article that you threw off, observing the mountain of clothing that you had created, absolutely shocked that you were wearing all of that beneath the covers that were over you.
“Jesus Christ, how many layers are you wearing?” He asked, the question being followed with a small chuckle. You glared up at him, your hands pausing at the waistband of your sweatpants as your teeth clattered again at the loss of clothing that was containing what little comfort and warmth you had.
“Unlike you, I need to contain as much heat as possible. It would be crazy of me not to layer up, I would freeze to death if I didn’t, so spare me the judgement.” You shot back, shimmying out of your sweatpants, not bothering to kick them off to the side as you pushed your two pairs of thermal leggings down, letting it join the pile at the end of the couch, leaving yourself in just your undergarments–a simple bra and a pair of long boxer briefs that you were using as another layer for your thighs.
You tightened your hold on the blankets, the fabric suddenly feeling lighter without the clothes that you were wearing. A gust of cold breath fogged the air in front of your face, while your body started to shake again, this time bordering on uncontrollable. The loss of these additional barriers left your skin stinging, the chill biting deeper now. Your fingers had grown numb, and patches of ice began to form across the plane of your stomach, the blanket sticking to the frozen spots where your body pressed against it.
“Hu-Hurry up and take your clothes off before I start turning into a human ic-ice sculpture.” You managed to say, the words breaking through the violent chattering of your teeth–echoing as if they were knocked loose. The sound snapped Sentry out of his momentary trance, and he made quick work of removing the sweat-soaked t-shirt, dragging it upward in one fluid motion. The damp fabric peeled away from his skin with a wet squishy sound before he let it drop onto the your own discarded clothes with a plop. His shorts followed next, shoved down the thick lines of his thighs, getting kicked aside without ceremony until he stood in nothing but his tight black boxer briefs.
Through the pounding ache beginning to build behind your eyes, you couldn’t look away from the bare expanse of him. The flushed skin that had been covered by his shirt was on full display now, ruby red and unevenly splotchy, with fresh beads sweat tracing down the ridges of his abs and disappearing against waistband of boxer briefs that hugged his thick muscly thighs that were the width of both your arms combined–not that you were looking to measure. The freckles on his skin carried an almost luminous quality to them, like they were glowing, creating this stark contrast against the ruby hue. He was an absolute adonis, perfectly sculptured and toned–like the God that he was.
If the cold hadn’t locked every other bodily reaction in place, you would’ve felt heat rise in your face at the sight. Instead, your expression laid your enamourment bare to him, eyes tracing every inch of his exposed skin with open appreciation. Sentry caught it immediately, a shy smile lifting on his lips.
“It’s odd seeing me without clothes, huh?” He teased, and even though you couldn’t verbally respond–because your heart kept staggering its beats–you nodded at him, letting your eyes do all the talking. He stepped towards you then, fingers catching the edge of your blankets and flipping them back to reveal your body to him, causing you to let out a little whine at the feeling of the air touching your bare skin. He could see the frosted patches that had already begun to spread up your stomach and thighs, delicate webs of ice forming and thickening in some spots, and that’s when he realized the real time crunch he was on.
He slipped his arm under your body, lifting you slightly and shifting you onto your side to make space for him, and instantly the both of you let out a joint sigh of relief, hearing his skin sizzling against yours at the contact. He immediately took up the spot he made for himself, laying down and adjusting his position before wrapping his large arms around you, pulling your body into his. He was so soft and warm that if you were able to cry you would’ve in those moments just from the sheer relief of him crowding you in. He slipped his thick leg between yours, getting as close as possible to you while he brought the blanket around you both, letting it rest just below your chests so it could seal the temperature exchange that was happening beneath it.
“Fuck…You really are cold,” He muttered, resting his broad palm between your shoulder blades, urging you nuzzle into him, feeling your soft cheek rubbing against the plush muscle at the top of his pec, finally gaining a semblance of movement back in your bones as the chill began to thaw.
“An-And you’re really hot.” You stuttered, closing your eyes at the heat, hearing a rough laugh escape his throat, quietly acknowledging the double entendre but not saying anything about it directly.
The smoky scent of his flesh had disappeared with the newfound closeness, and now he smelled like warmed skin and sunlight–naturally creamy and powdery with a hint of clean sweetness that was coming from the sweat that coated his skin. You were used to it–how it filled the room and overtook every space he was in–and often times you got lost in how perfectly it suited him.
He reminded you of summer days, when the heat felt like it was choking you because of how cloying and thick it became from the humidity, and you found yourself moving your arm over his torso, holding him tighter to absorb the warmth that slipped from his pores.
You felt like Icarus–flying too close to the sun but accepting your fate and absorbing the heat into your bones–but instead of wax wings it was your icy cool flesh that seemed to be melting, and you could feel water beginning to pebble and slip along your flesh until it sizzled and disappeared against him, followed by a gentle gust of steam that made your skin stick together.
He shifted against you once more, the solid weight of his body pressing deeper into the couch cushions beneath you that had began to dampen from the condensation that coated your skin, as the frame creaked in protest at the movement. For a moment he drew back, allowing a thin rush of cooler air to slip between your joined bodies, only for him to slide downward, shimmying so there wasn’t a complete loss of contact.
He settled his cheek against the soft swell of your breasts, chasing the cooling relief that poured from your body, needing the skin of his face to stop heating up. The wavy strands of his light brown hair spilled across your flesh, tickling the thin delicate skin beneath your chin as he moved. You tilted your head from side to side, trying to find a comfortable position that made sure the silken locks didn’t find their way between your parted lips, before resting your chin on the crown of his head.
Your arms moved of their own accord, sliding around his neck and drawing him in tighter so his face was squished against you. He let out a long sigh, letting his hands roam your back, his fingertips tracing heated shapes along the curve of your spin, each pass melting away the lingering patches of frost that hadn’t left your flesh. Against the plush cushion of your chest, his ears tuned into the steadying rhythm of your heartbeat as it finally found it natural cadence under the influence of his warmth, and he couldn’t help but smile at that–thankful that his plan was actually working.
“You feeling any better?” He asked, his voice sending a subtle vibration across your sensitive skin, his hot breath sticking over the tops of your breasts, sinking into your pores like a body oil.
“Yeah, definitely…I think if it wasn’t for this I would’ve ended up going into natural cryosleep…So thank you for preventing that.” You murmured. His fingers paused mid-motion, right when he was about to draw a triangle on one of your shoulder blades. He lifted his head slightly, his golden eyes meeting yours, as little hints of orange embers lined around his pupils, almost like his curiosity was sparking behind them.
The flush across his high cheekbones was already beginning to fade in uneven patching, revealing the pale porcelain-like tone beneath, and when your fingers moved to push a few strands of hair away from his face, the tiny flecks of orange brightened. You tucked them carefully behind his ears, and Sentry had to resist the temptation to lean into your touch, allowing you to make that choice for yourself on whether you wanted to keep feeling him like this–though he preferred that you kept doing it.
“Can that actually happen?” He questioned, the tightness of concern lacing his words. You nodded.
“It’s happened a few times. My body’s temperature plummets so much sometimes that all its systems basically go into hibernation mode to compensate. Usually I end up coming out of it a month or two later, but I typically don’t know what’s going on and it takes me a while to get used to my surroundings again…” You explained, watching his expression pull tight with worry–his brows drawing together, and his eyes widening slightly.
“That sounds…Scary.” He commented, his fingers twitching against your back, digging slightly into the soft flesh that lined your spine as if the mere thought made him want to pull you closer so that he could protect you from the possibility of that happening. You offered a small shrug in response, taking in a deep breath that caused your chest to expand beneath his chin.
“It was when it happened to me the first time…I didn’t really have anyone that cared about me back then, so I had to navigate everything on my own.” You said, ghosting your fingers along the side of his cheek, igniting a faint line of frost over the skin there which melted instantly–the droplets of water beading down his skin before evaporating with a small line of steam. You could see the way he was hanging off of every word you were saying, being the attentive listener he always was, and he waited for you to continue, silently encouraging you to keep opening up to him.
He secretly loved learning about you through the little anecdotes you dropped during missions, and oftentimes he found himself looking for more details, but he was always too afraid to ask–more because he didn’t want to make you feel uncomfortable. From what the rest of the team had told him though, he was well aware that you had been through a lot–disowned by your family at a very young age because they couldn’t handle your mutation, being passed around from facility to facility until you ran away to be on your own, discovering that you could use the power that you had for good…There was a lot of mirroring to his own story, but he couldn’t imagine all the other things you had gone through that you chose to hide.
“But thankfully that’s changed.” You added, giving him a small smile, watching his lashes flutter at the realization that you were talking about the team–and specifically him–with that comment.
“I’m glad.” He murmured, feeling your fingers trace along the freckles dusted across his cheek, connecting them with an invisible line.
“Me too…” You whispered back, reaching the bridge of his nose and trailing your soft touch down to the tip of it, feeling him let out a long shaky breath that clung to your flesh, his hand twitching against the small of your back. He leaned into your touch then, urging you to continue, basking in the coolness of your touch and enjoying the way it made his skin sizzle when there was a little surge of frost that escaped the tips of your fingers.
When you dragged them down to his lips you could see the way the embers in his eyes shimmered, glowing just a fraction brighter and you let out a little laugh.
“You like this?” You asked, moving your fingers over his thin top lip before doing the same to the bottom one, stopping in the middle of it when they parted, blowing a gentle gust of hot air against them that made your skin crackle slightly.
“I do…It feels nice.” He replied, the words vibrating over your fingertips as his lips brushed them in the faintest of kisses–like he was testing to see if you would pull away. When you kept your hand still for him though, he pressed his lips into the soft pads more fully, kissing each digit and leaving little wet spots behind that froze instantly on your flesh before melting against under his warmth.
Then he took your pointer finger into his mouth, the velvety heat of his tongue sliding along the pad until he reached your knuckle. Your throat tightened, pushing out a gasp from your mouth. He kept eye contact with you, the dark golden hue of his irises shifting to a richer saffron that glowed, like he had captured the sun behind his eyes. He sucked gently, hollowing his cheeks just enough to create a tight, warm seal around your finger, and you felt your stomach stir, your heart catching on a beat as an undeniable warmth ignited through you despite the biological coolness that wracked your system, feeling every nerve in your body light up so all you could focus on was the way his mouth felt.
He pulled off with a light pop and smeared the saliva on your finger along his face, closing his eyes at the wetness until it dried on his skin. He hummed low in his throat, a satisfied rumble that travelled through his chest and settled in your belly. Only then–when the spell of his mouth finally broke–did you move your hand to cup his cheek.
“Sentry,” You whispered, a hint of seriousness wrapping around his name like a quiet warning. He caught your tone immediately, gazing up at you, seeing the slight shock in your expression–the way your brows were pulled together, how your jaw had slackened just a fraction, the soft rapid breaths that escaped you…It was like you were processing what he had just done. He hadn’t meant to push; he had simply followed his instincts, desperate to show you how he felt, and he knew then that he shouldn’t have taken such a stupid approach to broaching the act of intimacy like this.
“Did I cross a line?” He asked sheepishly, pulling back just a little more to get a better look at you, though your hand on the back of his neck tightened, almost like you didn’t want him to move away at all.
“No…I…” You paused for a moment, seeing his eyes dart along your face as you bit the inside of your bottom lip–which he noticed, his golden gaze dropping to your mouth for a heartbeat before returning. “I’m just surprised.” You admitted quietly, and you could see the look of concern soften in his eyes, the tension easing from his shoulders.
He let the silence settle between you, until he let out a long breath and shimmied back up your body so he could be face to face with you. His nose bumped gently against yours as he shifted the leg wedged between yours, the thick muscle of his thigh pressing higher until it brushed the edge of your boxer briefs.
“In a good way?” He pressed curiously, sliding his hand from your back and leaving a slow-burning trail of heat in its wake as it travelled down the dip of your spine to settle at your hip. His large palm engulfed the curve there completely, his thumb stroking broad circles over the sensitive skin, coaxing fresh goosebumps to rise before the deeper chill of your body overtook the spot–only for his warmth to chase it away again in a subtle shimmer of melting frost that left your flesh glistening. You nodded, your gaze dropping briefly to his soft pink lips–slightly parted and glistening from the trace of saliva left behind by your finger–before flicking back up to meet his eyes.
“Yes.” You confirmed, your hand inching lower to cradle the side of his neck, your fingertips registering the rapid, heavy pulse hammering beneath his heated skin. He gave you a small smile, eyes dipping to your mouth now as his pupils flared wider and the scattered orange flecks within them brightened with unmistakable want.
“Can I kiss you?” He asked, not wanting to take your physical signs as permission, preferring to hear the answer fall from your mouth–needing to see your lips wrap around the words.
“Please, Sentry,” You breathed, leaning closer to him, bumping his nose against your as the two of you shared a brief moment of exchanged air. Then he closed the distance, pressing his lips to yours.
They were impossibly soft and searing, the contrasting pulling the air straight from your lungs. A little moan slipped from you as your hand tightened at the back of his neck, drawing him closer while his damp strands of hair brushed against your fingertips. He parted his mouth against yours and you followed, tongues sliding together in a slow, hungry glide that made you feel like someone had set a sparkler off right against your spine. His other hand rose to cradle the back of your head, fingers pressing into your scalp, holding you exactly where he wanted as he deepened the kiss, massaging his lips against yours with growing urgency. You laced your fingers into his hair and tugged lightly at the roots, earning a low groan from him, his hand tightening on your hip. You hiked your leg high, draping it over his hip so it rested against the thick muscle of his thigh. He adjusted instantly to you, his leg between yours fleeing upward until the firm ridge of his quads pressed flush against the gusset of your boxer briefs.
The sudden, solid pressure on your core made your hips jerk forward, a needy whine tearing from your throat at the heat radiating through the fabric, warming you immediately. Sentry held you through it, allowing the natural reaction to take over your body as it chased the friction it desperately craved, smiling into the kiss to silently convey to you exactly how much he loved the way you were reacting to him.
When he pulled back just enough to look at you, his cheeks burned a deep jammy red and his once-soft pink lips were now puffy and slick, glistening with the mess of your shared saliva. He could see a faint flicker of shyness cross your face, noticing the way your eyes widened for a split second as if the eager grind of your hips had surprised even you, and there was an instant moment where he felt the need to urge you to continue–to give you permission to use him.
He leaned in again, pressing slow, open-mouthed kisses along the curve of your cheek and jaw, each one leaving wet spots behind that cooled along your flesh. Your back arched toward him in response, tilting your head back to bare more of your throat to him as short, breathless gasps spilled from your parted lips. His teeth dragged lightly along the sensitive line of your jaw, the faint scrape of them being soothed by the flat of his tongue before he reached your ear and nipped at the fleshy lobe feeling you flinch, and drawing out another soft, broken sound from you.
“You can take what you need from me, Y/N…You don’t have to be embarrassed.” He whispered, his breath warming the shell of your ear, as his hand squeezed your hip gently–providing a reassuring pressure to your flesh. He trailed several more kisses down the column of your neck, letting his lips linger over the rapid flutter of your pulse, giving it a small lick and nuzzling against the frost that formed there to warm it.
Your fingers tightened in the damp strands of his hair you had in your grip, scratching your nails across the sensitive skin of his scalp, drawing a low, appreciative hum from him at the sting. He responded by guiding your hips forward, dragging you along his thigh. Every defined ridge of muscle pressed against you perfectly through the fabric, the contact so intense it felt as though nothing separated your aching core from his scorching skin. Your thighs clenched around him, slipping into the tingling heat that ignited low in your belly.
One of your hands slipped from his neck to brace against the broad plane of his shoulder, the contrast between your chilled palm and his overheated skin trudging up another burst of steam.
“Sen–Sentry…” You stuttered, his name shaking on your breath as he backpedaled along the same trail of kisses with his lips, moving up your jaw until he reached your mouth again. His golden eyes burned even brighter now, pupils blown wide as he registered–and felt–your heartbeat hammering wildly against his chest, a dizzying mix of nerves and arousal flooding through you.
“Y/N…It’s okay. Just rock your hips against me…I want to feel you,” He said, kissing the corner of your mouth with an aching gentleness that made your whole body seize, before blowing a warm breath across the little wet spot he left, “And I want to see you enjoy yourself and indulge…Please…Please grant me that.” He added softly, on the brink of desperation.
You couldn’t help the way your body yielded to his words–the tension melting from your muscles as you relaxed and loosened against him. He felt every shift, your weight bearing down onto his thigh with just enough pressure that he knew exactly what you were about to do.
Slowly, your hips began to move, rolling along the thick, flexing muscle with hesitance, adjusting yourself to get the position just right so the fabric of your boxers could rub across your clit, granting you the perfect amount of friction against the swelling bundle of nerves. You shivered against him, a burst of frost spiderwebbing across his shoulder before melting away, turning into droplets of water that slid down his chest, evaporating within seconds under the heat of him. His thumb rubbed slow circles into the soft flesh of your hip, pressing into it every so often as he leaned forward to claim your mouth again. His tongue slid against yours, teeth grazing your bottom lip while he pulled your body towards him, helping your find a steady rhythm that matched the frantic pulse that bounded through your veins.
His fingers dug gently into your scalp, holding you close as your breaths grew heavier, turning into soft, needy moans that he swallowed greedily–letting your noises fill him. You squeezed his shoulder harder, the fabric of your briefs clinging obscenely to you as you ground down onto him with increasing urgency, chasing the tightening coil of pleasure that tightened the muscles in your belly. You whined into his mouth, nails biting into his shoulder while you tugged at his hair with your other hand.
The friction wasn’t enough, and he could tell it wasn’t getting you to where you needed to be–sensing the frustration in your movements, the way you kept adjusting your position so that you could feel more of him, only for it not to change anything.
His hand left your hip then, his fingertips ghosting just beneath the waistband of your boxers, before sliding beneath it, trailing his touch to your pubic bone, settling it there for a moment. He shifted his thigh down, and the sudden loss of pressure drew a soft moan from you, but the absence of it was replaced almost instantly by his fingers tracing along the heat of your folds. He let out a groan of surprise, pulling back from your lips just enough to breath heavily against the saliva he left there, his eyes fluttering open to meet yours, a pleased smile curving up on his mouth.
“I was expecting you to be cold here…But you’re…You’re warm. So fucking warm.” He said, marvelling at the discovery as his fingers ran slowly through your folds, savouring the silky softness of your skin while your arousal coated him.
Your breath caught in your throat, head tilting back as your lashes fluttered against the overwhelming sensation of his fingers exploring you, your body tingling with every pass. His lips pressed gentle, open-mouthed kisses over your jaw, each one leaving a warm imprint that made your skin numb where frost tried and failed to form.
When he moved lower, circling your sensitive entrance with the pads of two thick fingers, he felt the way you pulsed and clenched against him, your hips pressing down in silent urgency, wordlessly begging him to push inside. But he held back, drawing the moment out with torturous patients, wanting to hear you break and beg before he gave you what your body was demanding.
He smeared your arousal up to your swollen clit, covering the throbbing bundle completely with slow, gentle circles that had your thighs trembling. You arched into his touch, urging him to give you more, your nails scraping over his shoulder but doing limited damage to him. It felt better than your own fingers, and it was evident he knew exactly where to touch you to drive you crazy, finding a perfect pressure that made the nub swell even further.
“Sentry…Sentry please.” You breathed, voice cracking with desperation. He hummed against your skin at the sound of your pleas, nibbling at your jaw before licking the spot.
“Please what?” He asked, looking up at you through heavy lashes while your eyes squeezed shut.
“Please give me more…I need more.” You begged, the words tumbling out like you were on the verge of tears, your mind clouded by a thick haze of lust that made every though narrow down to the slow, teasing drag of his fingers. He let out a long, heated breath that clung to your skin, nodding once as strands of his hair tickled your cheek.
“All you had to do was ask.” The teasing edge in his voice sent a fresh shiver racing through you, your stomach stirring and clenching. He brought his fingers back down to your entrance, tracing the muscle for one moment before pushing inside you in a smooth, soul catching stroke.
You sighed out a broken sound of relief, your walls clenching around the invading heat of his fingers, welcoming him immediately. The stretch was perfect–filling you like a cock would–every ridge and knuckle dragging along your sensitive inner walls until he was buried to the hilt. He curled them deep, stroking firmly against the spongy spot inside you while his thumb found your clit again, pressing steady circles over it.
Frost bloomed up his forearm and his lips turned up into a smile against your throat–proud that he could make you lose control of your powers so easily, relishing in the way the phantom air of you clung to his flesh before evaporating completely.
His fingers began pumping steadily, setting a rhythm that had your hips rocking helplessly against his hand. His lips met yours again, but this time the kiss was slower, softer, bordering on sensual. He parted his mouth over yours just enough to taste the cool rush of your breath flooding his lungs before sucking your bottom lip between his, pulling on it gently until it swelled and filled with blood under his attention. You clenched hard around his fingers, thighs tightening around his wrist, grinding down on his hand in earnest, riding every thrust, digging you hand into his shoulder even more to keep a steady pace.
He put more pressure on your clit, rubbing faster, tighter circles along the bundle of nerves, curling his fingers harder against that spongy rigid spot inside you. Your ears began to ring like a stun grenade had gone off inside your head, the world narrowing to nothing but the wet sounds of his fingers working you open and the overwhelming heat coiling tighter and tighter in your core. You became a blubbering mess, trying to form words, but all you could say was his name over and over again, like a mantra–like a prayer of mercy.
“Mmph–Oh god!” You managed to say, feeling a wave of heat exploding over your skin–whether from him or the pleasure itself, you couldn’t tell–as your body shook against his. Your walls clenched tighter around his fingers, pulsing in a fast, rhythmic flutter until you gushed over his hand with a loud, broken whine. Tears stung at the corners of your eyes from the intensity of it, your nails scraping down his shoulder blade as overwhelming relief flooded every nerve.
Sentry moved to the dewy drops, licking the salty beads before they could even fall along your skin, slowing his fingers down gradually, savouring the way you kept pulsing and fluttering around them, your body shivering from the overstimulation that rattled through your nervous system.
“See? Wasn’t so bad letting yourself go, hmm?” He whispered, pressing a soft kiss to your temple. You shook your head weakly–like your bones had turned to jelly–chest heaving with each breath you took.
“No…No…That was fucking perfect.” He pulled back just enough to flash you a toothy grin, the embers of orange around his pupils and framing his irises setting alight with satisfaction.
“I’m glad.” He replied, slipping his fingers free with a wet sound that made your cheeks heat, then dragged them slowly up your stomach, smearing the glistening evidence of your release across your skin in lazy streaks. He brought the slick digits up between you both, spreading them apart to show you the honey-like sheen the connected them in translucent webs, the sight so filthy and intimate that it made your stomach clench all over again.
Light bounced off the glossiness, shimmering across his skin like liquid gold before he brought his fingers to his mouth, sucking on them. You tasted salty and sweet, like a savoury dessert, laced with something mineral-like, almost cold in a way like chilled syrup. He let out a little moan, drawing his fingers out slowly, dragging the flat of his tongue along each pad until every trace of your arousal was gone, leaving only the faint sheen of his own saliva.
“Mmm…You taste amazing…Makes me want to try it straight from the source.” He murmured, pressing a small kiss to the corner of your mouth, putting his weight into you so that you shifted onto your back. A look of confusion drew across your face–brows pulling together, a little frown forming on your lips–and you shook your head.
“What about you? Don’t you want me to do anything to you?” You questioned, watching as he adjusted himself above you, his knees sinking into the couch cushion so he could spread your thighs wider and settle fully between them, the blanket falling off the side of the couch. He pressed his chest against your stomach, peering up at you through his lashes, a soft laugh of disbelief escaping him.
“Trust me, this is doing a lot for me,” He commented, taking your hand in his and guiding it down to the front of his briefs, letting you feel the warm, daunting thickness of his erection straining against the fabric, heavy and pulsing under your palm. You hadn’t noticed it when you were grinding on his thigh, but now the sheer size and heat of him made fresh heat boom low in your belly again. Your fingers curled around him, giving a gentle squeeze, your thumb brushing over the small wet patch of precum that had soaked through the material. He twitched hard against your touch.
“You didn’t even have to touch me and this happened…So just lay back and let me get a better taste of you.” He said, pressing a kiss to your belly. When you gave his cock another squeeze, he hissed softly, then carefully took your hand off him to settle your palm flat against your stomach, right over the spot his lips had just warmed. He held it there for a moment, letting a thin layer of frost bloom beneath your fingers to preserve the faint imprint of his kiss like a brand against your skin.
“Okay…” You breathed, settling back against the cushions, using the arm rest to angle your head just enough so you could watch him. He kissed along your hips, slipping his fingers beneath the waistband of your boxers and pulling them down your legs in one smooth motion. You helped by lifting your legs, bending them until the fabric slid free. He tossed it aside without a glance, then pushed your thighs open again, one foot bracing on the floor so he could lay comfortably between them.
He stared at the glistening trails of your arousal pulsing from your core as you clenched around nothing, pushing more sweetness out of you, and he couldn’t help but lick his lips at the sight–like he was a dehydrated man looking at a fountain of fresh ice cold water. He rubbed your inner thigh, the heat of his palm sinking deep into your chilled skin as he gave the soft flesh a firm squeeze.
“All wet just from my fingers…Absolutely breathtaking.” He admired, voice thick with hunger. He leaned down, chest pressing into the yielding cushions, his hot lips peppering a slow pathway of kisses up toward your core. He nuzzled his cheek into the cool skin right at the apex of your thigh, breathing you in deeply–your scent was sweet and icy, like ripened fruit laced with peppermint. A beautiful haze of euphoria washed over his features as he kissed along your pubic bone before pressing his shoulders beneath the backs of your thighs, spreading you open wider and locking you firmly in place.
He glanced up at you, catching the way your kiss-bitten lips parted on a shaky breath. His hands moved to your core, opening your folds up to him before he pressed his tongue flat against you. The first long, slow lick pulled a gasp from your throat, your hand shooting down to lace tightly through his hair. You were so sensitive from your first orgasm that every pass of his tongue felt like liquid fire pouring into your veins, reigniting the heat deep in your belly all over again.
He buried his face in you completely, head moving slowly so his tongue could part you more, licking deep inside, tasting every drop while smearing your arousal across his chin and cheeks. Low, filthy moans vibrated against your core as he devoured you, his hand gripping at your thighs, fingers dimpling the soft flesh, sliding his tongue higher to circle your clit before sucking it between his lips. He flicked the swollen bundle, eyes never leaving yours, holding you captive under that golden stare while your fingers massaged through his hair.
“God, Sentry…Ho-Holy fuck.” You whined, hips shifting helplessly beneath him. He moaned into you in reply. The noises that echoed through the room were wet, his mouth sucking on your folds and your clit, burrowing deeper before pressing his tongue into you and tasting you straight from the source, doing it over and over again. It was like he was making out with your pussy, his experienced mouth taking all everything you gave to him with ease. You bucked against his mouth again, and he brought his hand up to your hip, pinning you to the couch cushions, holding you still so that he can keep his rhythm exact, sharp focusing on dragging a second orgasm out of you that would eclipse the first.
He felt your thighs trembling against his shoulders, the muscles quivering with every pass of his tongue. Your free hand found the one he had dug into the top of your thigh, fingers lacing tightly with his as he squeezed back in silent reassurance, another grunt vibrating through you. The pressure of his tongue grew heavier, more insistent, as he continued to devour you without thought.
The lamp on the stand beside the couch suddenly brightened, its glow pulsing in time with the waves of pleasure rolling through you, and your eyes flicked to it for a brief second before dropping back down to him, catching the way his irises glowed like captured sunlight–bright and molten. You knew it was him doing this–you certainly weren’t capable of doing that–and a stifled laugh escaped you as the light flickered again, like he was speaking to you in bursts of golden morse code
You could feel him smile into you, plunging his tongue into your entrance one more time before moving back up to your clit again, his lips wrapping around the swollen bundle, snapping you out of the moment of humour and dragging you back into the overwhelming sensation of his mouth.
You took in a sharp breath.
“Sentry! Oh fuck…Please, right there!” You whined, your thighs clenching hard around his head, fingers pulling at his hair as your hips bucked against the firm hold he had on you. He kept sucking, swirling his tongue in tight circles while pressing his face deeper, the wet sounds of his mouth on you filling the silence.
The coil in your belly tightened unbearably fast, as his lips sealed over you one last time, making it snap instantly. You came hard with a broken cry, your back arching off the couch as your core pulsed against his chin. A powerful wave of frost bloomed across his shoulders and down his arms, racing over his skin like you got a surge of energy from your orgasm.
He couldn’t stop licking you, craving every shudder, greedy for every last drop until you were a trembling, oversensitive mess beneath him, your thighs shaking uncontrollably and your breath stuttering.
“Yo-You need to stop, I’m gonna turn you into a piece of ice if your don’t.” You warned quickly, forcing your thighs to loosen from around his head so he could breathe and move away from you. He hummed in response, the vibration sending one last aftershock through your body, before he pulled back, placing one final open-mouthed kiss against your quivering core.
“I’ve got the power of the sun coursing through my veins, you wouldn’t be able to do anything to me…And honestly, I actually like when you get all chilly–shows me I did a pretty good job.” He commented, his voice a low, velvet rumble that shook against your stomach as he began kissing his way upward. His lips dragged slowly over the soft give of your belly, glistening with the sheen of your release that coated his chin and mouth.
Everywhere he touched, he smeared the slick evidence of your pleasure across your chilled skin in warm, glistening streaks, the contrast drawing faint curls of steam that rose through the air lazily like hot breath on a chilled window. His teeth grazed the tender flesh just above your navel, a gentle nip that made your muscles flutter and tighten beneath him, followed by the immediate heat of his soothing tongue that lapped away the sting. He nipped your again, just below your ribs, and you felt yourself arch into him, your skin prickling with fresh goosebumps.
“But I’ll give you a break since you need one so badly,” He added, the words husky and teasing as he pushed himself up on his powerful arms, the thick cords of muscle in his shoulders and biceps flexing with the motion. He hovered over you for a moment, his golden eyes locking on yours, the orange embers around his irises flickering like distant stars caught in the pull of desire. Then he lowered himself, claiming your mouth in a deep, sticky kiss that stole your breath from your lungs, his lips parting against yours to let you taste the salty-sweet tang of yourself on his tongue as it slid hot along yours.
The flavour of your own arousal mixed with the clean, sun-warmed scent of his skin, and you let out a small moan, your hand flying up to cradle the side of his neck, fingers pressing into the strong column of muscle there, feeling the throb of his pulse beneath the heated flesh. You tilted your head up to chase the kiss, tongues tangling with wet, needy sounds escaping the both of you, until he finally pulled back to trail kisses along the curve of your cheek and jaw, his breathing rapid and ghosting over your flesh.
You laid beneath him, chest rising and falling in ragged little pants, every inch of you humming, trying to come down from the euphoric high your orgasm put you in. The heavy weight of his body pressed you deeper into the couch cushions, the heat radiating through his chest and abdomen sinking into your bones like liquid sunlight.
Your thighs cradled his hips, legs locking around his to draw him nearer, the thick outline of his cock pressing hot through the thin barrier of his briefs. It rested just above your aching core, the searing length of him throbbing against your lower belly, feeling the fabric was now saturated in his precum–which had only grown larger while he had feasted on you. Small, translucent droplets seeped through the material, smearing against your skin, creating this sticky warm film there.
You were so tempted to reach down, to slip your fingers beneath his waistband and wrap them around that daunting thickness, to test whether your hand could even close fully around him, to feel the velvet-steel weight of his cock pulse against your palm. But you held yourself back, nails digging into him for a moment. You truly needed the break, knowing that the moment he finally pushed inside you would shatter what little composure you had left–and losing your mind entirely was something you were trying very hard to avoid right now.
So you made quick work of finding a distraction for yourself.
“…Can I ask why you were flickering the light like a maniac while you were going down on me?” You asked, carding your fingers through his hair and gently tugging at the roots. He let out a little huff of a laugh against the sensitive skin of your neck, the warm gust of it raising fresh goosebumps that ran up to your chin, as he pressed another kiss there.
“It kind of just happens when I’m feeling really good. My brain is focusing on something else then my powers fall out of my control and it does whatever it can to get out the excess energy.” You hummed softly in response, tilting your heat to the side to allow him to continue his explorations. Then suddenly, your brows pulled together as a realization dawned on you, cutting through the lingering haze of pleasure.
“Wait a minute…Is that why we sometimes have a ‘power surge’ in the middle of the night and wake up to every fuse in the Watchtower being blown out?” His lips curved up into a shy smile against your skin, the warmth of it branding the junction where your neck met your shoulder.
“Guilty as charged,” He mumbled, the words muffling where his mouth had settled, sending a fresh shiver racing down your spine that clashed deliciously with the steady heat pouring off his chest. A soft, playful laugh bubbled out of you, pushing against his broad shoulder, your palm meeting the solid muscle there with no real force.
“I knew it was you! Everyone was denying it and calling me crazy!” He let out a rumbling laugh of his own, the deep sound vibrating against your breasts as he nuzzled closer, his large hand sliding up your torso with a slow, possessive glide. His palm spanned the entire width of your ribcage, his thumb slipping beneath the underwire of your bra to brush the plush underside of your breast, the calloused pad teasing the sensitive skin until your nipple tightened.
“Well, now you know. Let’s not go spreading that around though…Cause I will vehemently deny it.” Your smile widened at that.
“Your secret is safe with me.” You reassured, flinching when he gave the underside of your breast a little pinch, rubbing the spot to soothe it.
“Can I take this off?” He asked, his golden eyes flicking down to the bra still clinging to your frame, the last scrap of fabric separating skin from skin. You nodded, breath catching as his free hand slipped behind your back, his fingers unhooking the clasp before slowly peeling the straps down your arms, and letting it drop off the side of the couch with the rest of your discarded clothes. You were glad that nobody was coming home anytime soon because there was no way the two of you would be able to clean the mess that was scattered along the floor.
He leaned up on his forearm, drinking in the sight of you, watching the way your nipples pebbled at the sudden exposure, running his thick finger over the bud, the pad covering it entirely before he cupped the full weight of your breast in his large palm, squeezing with just enough pressure to draw a soft gasp from your throat. You twirled a strand of his hair around your finger, watching the light brown colour catch with golden highlights from the lamp.
“I feel overdressed,” He commented, glancing down at his boxers, and you couldn’t help but smirk.
“Maybe you should get undressed then to make it even.” You replied, feeling his fingers twitch against your breast before he nodded.
“Fair enough,” He whispered, his hands leaving you as he pushed off you and reached down to his waistband, pushing the fabric down just enough so his cock sprang out of its confines, bobbing and tapping against his lower belly, before standing erect between his legs. The outline certainly didn’t do him justice, and seeing it in the flesh was far more intimidating than feeling it against you. The crown was large and red, swollen from him holding back this entire time, and the shaft was thick and veined along the smooth skin that led down to the trimmed hair at his base. He kicked the boxers aside without a glance, then settled back between your spread thighs, adjusting himself so the scorching length of his cock rested flush against your belly, the hot, velvety weight of it twitching and leaking fresh beads of precum that smeared over your flesh.
You let out a sigh, your fingers trailing down the sweat-slicked planes of his abdomen, following the deep cuts of muscle until they wrapped around the tick base of his cock. Your hand barely closed around the heavy girth, the velvet heat of him pulsing against your chilled palm. You stroked him once from base to tip, feeling every ridge and vein drag beneath your touch, the skin stretched taut and burning. His lashes fluttered shut, a sharp hiss escaping through clenched teeth as his hips jerked forward into your fist, chasing the friction with a helpless little gasp that broke from deep in his chest.
Your thumb swept over the slick head, spreading the steady leak of precum in lazy circles before you stroked him again, firmer this time, twisting your wrist just enough to hear him groan. You kept the rhythm precise and unhurried, watching the way his powerful body trembled above you, the flush on his chest deepening as steam began to radiate off of him.
“Fuck, Y/N,” He groaned, voice wrecked as he reached down to catch your wrist, guiding your hand away from his aching length before he lost the last fragile thread of control. “If you keep touching me like that, this is going to be over before I even get inside you.” He said, pinning your hand beside your head, fingers sliding down your forearm in a heated trail melting the frost that bloomed on your flesh, before he leaned in to press a small, tender kiss to your lips, rubbing his nose gently against yours.
“Do you want that?” He asked, his golden eyes searching yours, the orange embers sparking and swirling around his irises.
“No…” You breathed, the word barely more than a whisper as you brought your legs up to wrap loosely around his waist, heels digging into the firm, rounded muscle of his ass to pull him closer, “I’d prefer to feel you cum inside me rather than in my hand.” He let out a hot breath against your lips, the warm rush filling your mouth and slipping down your throat.
“So…Does this mean you’re ready?” He questioned, as the tips of your fingers glided along the broad slope of his shoulder, tracing the muscle.
“Yes,” You said, the single word heavy with want, and he didn’t need to be told twice to confirm it with you. Slowly, he shifted his weight, creating just enough space between your bodies to reach down and grip the base of his cock. The swollen head nudged through your folds, coating himself in the slick evidence of your arousal, sliding hot and smooth along your slit before circling once over your swollen clit, teasing it, before bringing it back down.
He notched himself at your entrance, pausing to glance up at you, his eyes locking on yours to make sure there wasn’t even a hint of hesitation, and when you pressed your heels harder into his ass, urging him forward, he took it as permission to go on–that you were sure.
He brought his hips forward in one controlled push, feeling your walls part around his thickness, the broad crown sinking in immediately. The stretch was overwhelming even though it was only the tip that had breached you, and your breath caught in your throat, chest rising as your body adjusted to the warmth that was filling you. He waited, perfectly still, leaning down to press a soft kiss to your cheek, a quiet sigh escaping him as your walls pulsed and fluttered around him.
“Are you okay? Does it hurt?” He asked, concern threading through his voice, studying the way your breath hitched and how your hands had gripped his shoulders just a fraction more, nailing sinking into the muscle.
“No it doesn’t hurt…I’m just getting used to you. Keep going,” You urged, thighs tightening around his torso. He continued to push forward, your walls fluttering around each new inch he gave you, feeling every ridge and vein dragging inside you until he was finally buried to the hilt. The fullness was unbelievable–his cock seated so deep you could feel him pressing against your cervix.
He stilled above you, chest heaving against your in deep, ragged pulls of breath as he pressed his forehead to your temple. His frame trembled, muscles locking tight beneath your palms, his body fighting the urge to lose himself completely in the tight, fluttering grip of you. He wanted this to feel as good for you as it already did for him; he refused to rush, refused to risk hurting you for even a second.
A few minutes passed in silence, until you rocked your hips against him, testing the depth, and turned your head just enough to catch his lips in a deep, needy kiss. He let out a heavy breath through his nose, the warm rush of it flooding your senses as he finally gave in.
He drew back almost to the tip, the drag of his thick length sending sparks exploding through every nerve, before he rolled his hips forward in one powerful thrust that punched the air straight from your lungs. A keening moan tore from your throat as the blunt head of his cock kissed the deepest part of you as softly as he could. He pulled away from your mouth, closing his eyes tightly.
“God…You feel so good,” He breathed, the words breaking as he felt your nails dragging down his shoulders, leaving faint red trails the disappeared before they could even settle into his skin. He found a steady rhythm then, rocking his hips in deep, claiming strokes that drove every inch of him into you with each forward snap, the wet slap of skin meeting skin echoing through the room as your arousal coated him, smearing along his pelvis.
His mouth found yours again in a messy, desperate kiss, tongues sliding together in hungry strokes while one large hand came up to cup your breast fully, his thumb circling the tight, pebbled peak of your nipple before pinching it hard enough to make your walls clench around his cock like a vice. A whimper spilled from you, broken and needy, as your nails scraped down his back in response, the sharp sting only spurring him on.
His hand left your breast then as he slid both arms beneath you, craving a better angle, the thick cords of muscle in his biceps flexing as he lifted your body towards his until you were sitting on his lap. The sudden change in position made you whine, the new angle letting him sink even deeper, pressing against the places inside you that stole every inch of air out of your lungs. It was as if you could feel him in your stomach, pulsing and twitching inside, taking up more space like he wanted to invade your entirety. Your arms came up to wrap around his neck, clinging to him as you steadied yourself against the solid wall of his chest.
He pulled away from the kiss, trailing his lips down the column of your neck in hot, open-mouthed paths, licking and sucking at any skin he came into contact with, leaving marks that bloomed wide. When he reached your breast he enclosed his mouth around one stiff nipple, drawing it deep between his lips with a low groan that vibrated through the soft, tender tissue. You let out a loud moan, arching your back into him, lacing your fingers through his hair and pulling as his tongue flicked rapidly over the hardened bud.
“Jesus Christ, Sentry!” You cried out, the words breaking on a gasp as his hands settled on your hips, guiding you into a steady rhythm so you could ride him comfortably. His tongue continued its relentless assault on your nipple, sucking and teasing until your thighs trembled around his waist, sending waves of fresh frost up his torso.
The new position let you control the pace, and he allowed it, his large hands splaying wide across the curve of your back as you rolled your hips in deep, grinding circles. Each motion dragged the thick length of his cock through you, the heavy motion stretching you open again and again while he thrusted up to meet you, his pelvis rubbing against your swollen clit with every roll. The added pressure layered the sensations perfectly, your arousal coating him even more, dripping down to soak the skin of his thighs where the pressed against you.
Your moans grew louder, filling the lounge as his hand skimmed up the length of your spine to cradle the nape of your neck, while the other gripped the soft flesh of your ass, helping you lift off him so he could guide you back down onto him with every roll. The wet, rhythmic slap of skin meeting skin echoed louder now, obscene and perfect, each impact sending fresh waves of heat between your joined bodies.
He pulled off your nipple with a pop, breathing heavily against your skin as he moved his mouth to the other breast, enclosing the stiff peak between his lips with the same intensity. His tongue flicked and swirled, sucking hard enough to pull more of your breast into him, a loud moan tearing fro your throat as you laced your fingers tighter through his hair and tugged.
He loved the way you gripped him, the way your walls fluttered and clenched around his cock like you never wanted to let him go, like you wanted to stay like this forever, hearing the broken compliments and needy sounds spilling from your lips in a jumbled mess that only made him thrust up harder.
You rode him like you couldn’t do anything else, nails digging into his scalp as the coil in your belly tightened, every deep grind of his cock and every relentless flick of his tongue pushing you right to the edge. The lamp beside the couch began to flicker again, pulsing once before flaring brighter, as the thawed ice pack fell to the ground with a soft plop. You didn’t lose focus for a second though; the erratic glow only confirming how good he was feeling too, how close he was, how desperately he needed you.
His fingers dug harder into the flesh of your ass, a low moan vibrating through your breast as he felt you fluttering wildly around him.
“Sentry! Sentry I’m gonna cum again.” You whined, and he hummed against you, not wanting to let go of your breast.
“Give it to me, Y/N…I got you.” He said with his mouth full of you, and that was all the encouragement you needed as you shattered around his cock with a broken cry, your walls pulsing and fluttering in rhythmic waves that milked his thick length, soaking him even more in your slick. Frost exploded across his chest and arms, invading his mouth, making his teeth nibble down on your nipple from the chattering which pulled a surprised gasp from your throat. He grunted, his hips stuttering up into you a few more times before they locked up, burying himself to the hilt as he spilled inside you.
His cum felt scorching hot, almost like it was burning your insides in the most exquisite way, as thick ropes flooded your core, feeling pulse after heavy pulse coating your walls until it overflowed, spilling out around his cock and mixing with your own release on his thighs. The sensation of him filling you so completely, so deeply, sent another wave of relief crashing through your body.
The both of you trembled, gasping for air, bodies locking together in the aftershocks that raced through your muscles, and slowly the brightness of the lamp eased, just like the frost that had momentarily overtaken his skin. He let out a breathless moan, releasing your nipple before looking up at you, his golden eyes soft and hazed with pure satisfaction.
“You’re a godsend,” He whispered, leaning up to press a small, tender kiss to your lips before carefully lowering you both back down onto the couch, making sure he was still buried inside you as he nuzzled into the crook of your neck. The heat of him was now perfectly balancing your cooled skin, and every point of contact hummed with shared relief and warmth.
“Feels like we found a cheat code to the whole temperature crisis thing.” You joked, catching your breath, earning a little laugh from him.
“We might have to keep testing it just to make sure…” You nodded.
“I definitely wouldn’t mind that.” You commented, as he pressed a kiss to your neck, biting down where your pulse fluttered against his tongue. You trailed your fingers over his back, tracing the deep valley of his spine, basking in the comfortable silence of the afterglow, until he cleared his throat.
“I know this may not be the right time to ask given that I just came inside you…But…What do you think would happen if we ended up…” He trailed off, looking up at you in hopes that you knew where he was going with the question, seeing the lustful haze that clouded your eyes.
“Having a child together?” You said, finishing it for him, and he nodded slowly, keeping his gaze on yours, seeing the way you were considering the answer in your mind, like you never truly thought about the topic because it wasn’t something that had ever come up in your entire life.
Sure, you had been to a lot of scientists and doctors who practically tore you apart piece by piece just to test your genetic makeup, but even then they never asked about if you ever wanted to have children, which meant you never explored what could happen in that process. Now that the question was posed though, you had to take a moment to reflect on it, because it wasn’t just about your own mutation being passed down in this circumstance, it was also about his.
You bit the inside of your cheek, your eyes roaming his, seeing that the bright lustre that had overtaken them had eased, allowing his irises to return to a dimmed sun-kissed hue.
“It would be an easy answer if you didn’t have the serum, but factoring in that you do and that we are practically on the complete opposite ends of the temperature scale, I really don’t know what would happen…We might end up making a super mutation or something.” You joked, feeling his hand run up your torso.
“Sounds dangerous…” He murmured, and you nodded at him.
“It probably is…They’d probably end up taking them away if we had one.” He didn’t really know who you were referring to, but he could hear the fear that suddenly encompassed your voice, and his arm tightened around you, pulling you impossibly closer to him, wanting to comfort you immediately.
“I wouldn’t allow that to happen, you know that.” You gave him a small smile, bringing your hand up to cradle his cheek.
“Of course I do, you’re already extremely protective of me during missions, I couldn’t imagine how you’d be with a baby.” His lips turned up into a smile, tilting his head to press a kiss to your palm.
“Do you like the protectiveness though?” He questioned, and you shrugged.
“I don’t mind it…Makes me feel like I’m special to you.” He pressed another kiss to your hand.
“You are…And I won’t let you forget that.”
