No content warnings needed, but there is a threesome!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Light rain tapped at the window. A warm glow from the single lit lamp and TV enveloped the room. A soft blanket hid your legs leaned against Dick’s. His arm wrapped around your shoulder, with his thumb gently rubbing back and forth over your bare skin. It was the simple moments like these that made all the horrors of Gotham worth it.
A content sigh slipped from your lips, and you shuffled closer to Dick. Your leg swung over his, and your arm stretched across his solid chest. He pulled you into him, wrapping his other arm around you, and pressed a kiss to your forehead. The movie playing faded to the background as his hand skimmed up and down your body. His fingers slid underneath the hem of the shirt you’d borrowed from him, the one that was just oversized enough to pass as a sleep-shirt, slowly pushing it up higher and higher. A small murmur escaped you, and you pressed light kisses to his neck.
Right as his hand reached your hip, a rapping at the door interrupted. You pulled back with a slight groan.
“Ugh, the pizza guy always comes at the worst time,” you complained while getting up. You grabbed some cash from your wallet before answering the door.
Except, your usual pizza guy wasn’t on the other side. Instead, a handsome young man stood at your doorstep. He wore a blue and yellow spandex suit, like a brighter version of Dick’s, and held some kind of mask in his hand - with no pizza in sight.
“Oh, hi, um. Is there a, uh, Richard Grayson here?”
Your eyes narrowed at him. Almost no one called Dick “Richard,” certainly not strangers who randomly show up at his doorstep.
“Who are you?” you asked, slightly closing the ajar door.
“Right, sorry- I’m Mark, Mark Grayson,” he held out his hand, but you made no move to take it. When he realized you weren’t going to, it fell, and he continued on, “I know this is going to sound strange, but I’m from another universe. I got stuck here, and I think Richard Grayson is your universe’s version of me.”
You took a step back, closing the door even more. Only a narrow gap let you see him now. In a world full of aliens and magic and superpowered beings, alternate universes weren’t exactly the craziest thing you’d heard just this week. But, you were in Gotham, and you wouldn’t put it past any one of Dick’s enemies to pull this kind of stunt. It was just as likely he was lying as telling the truth.
You felt Dick’s presence behind you before you felt his hand on the small of his back. His other hand held the side of the door, opening it back up. “People usually call me Dick,” he said, skeptical and cautious. The strange man seemed to smile.
“Sorry, all the news articles I read called you Richard. You’re Nightwing, right?”
Now it was Dick’s turn to narrow his eyes. “Why would you think that?”
“Well, the only other Graysons in Gotham are elderly, kids, or dead,” ‘Mark’ laughed, “I just figured if you’re this universe’s version of me, you’d be Nightwing.”
Your eyes darted between the two men. They did share some similarities. Both were of a similar height and age, with the same lean, muscular build. ‘Mark’ was slightly tanner, though they had the same sharp jawline and pitch black hair. The most noticeable difference was their eyes; ‘Mark’s’ were brown, not blue, and slightly smaller than Dick’s.
“If you’re from another universe, how’d you get here?” you asked him.
He sighed. “It’s a long story, but basically, this guy who can open portals to other universes has - had - a vengeance against me. He threatened my family, baiting me through his portals, and I… I got stuck here.” His voice was full of emotion, raw and earnest. Despite his earnestness, it seemed like he wasn’t telling you the full truth. “I just thought maybe you could help me get back home.”
He looked towards Dick, his eyes full of sadness, and your heart melted. He could be lying, but if he wasn’t, you had to help him.
You reached across Dick and pushed the door open before stepping back. “We’ll help. Come in.” Mark’s face lit up as he stepped into the apartment.
“What?” Dick exclaimed, failing to quiet his voice.
“If he’s telling the truth, we have to help,” you whispered back, glaring at him.
Mark stood in the center of your living room, looking around at your decorations. Now that he wasn’t behind a door, you could see his full, toned, body. Even his ass was similar to Dick’s.
“So, what do you want us to do?” Dick questioned him, crossing his arms over his chest.
“Well… maybe you could call Cecil?” Mark asked. You and Dick looked at each other in confusion.
“Who’s Cecil?” you asked.
“You know, head of the GDA? Grumpy balding dude? Always teleporting in at the worst time?”
Seeing the continued confusion on your faces, Mark’s expression fell. The sadness on his face tugged at your heartstrings. You had to help him. “We have Batman,” you offered.
It was Mark’s turn to be confused. “Who’s Batman?”
You and Dick looked at each other again, silently communicating. Clearly, he really was from an alternate universe - one very different from yours. This was going to take longer than you initially thought.
“You know what, it’s late. Why don’t you crash here for the night, and we’ll figure this out tomorrow?” Dick offered. Mark smiled, though it seemed hollow, and nodded. Dick showed him around the small apartment while you resettled on the couch. The rain had subsided, leaving you to the quiet peace of night. Eventually, the two men returned to the living room. Mark had changed out of his suit and into Dick’s old clothes. He looked so normal now, like any other guy.
“So, you’ll sleep on the couch tonight, ok?”
Mark nodded. He fidgeted with his hands and avoided eye contact with you. It was kind of sweet he was so nervous. Dick plopped back down on the couch next to you and swung his arm around your shoulder. You leaned into him, though you didn’t intertwine your body with his the way you did before.
“You wanna finish this movie with us?” you asked Mark. That seemed to perk him up.
He sat down on the other side of you, hesitantly sinking into the cushion. Dick unpaused the movie, and the three of you settled in. As he relaxed more, Mark’s knee gradually grew closer until it brushed against your knee. The slight contact sent sparks through your leg. Your stomach churned at the realization. Your boyfriend was right next to you, but you made no effort to move your knee away from him. Noticing it, Dick grabbed the discarded blanket from earlier and not-so-subtly tucked it between your knees. His grip on your shoulder tightened, and you shuffled closer to reassure him, pressing a kiss to his cheek.
When the movie ended, Dick practically dragged you off the couch. You quickly said goodnight to Mark before letting Dick lead you into your bedroom.
“Dick, what is your problem?” you asked once the door was closed, keeping your voice hushed.
“I don’t trust this guy,” he said incredulously, “and you just invited him into our home without even asking me! What if he’s not who he says he is?”
You stepped forward, placing your hands in his. “Then we’ll deal with that, same as we always do. But even if there’s only a one percent chance he’s telling the truth, we have to act like he is, and help him.” Dick still looked unconvinced, but marginally less distressed. “It’s just for tonight,” you reassured him.
He let out a deep exhale and nodded. “Just for tonight.”
Tonight turned into two nights. Two nights into three, then three into four, until it had been over a week. Dick - or rather, Nightwing - had called on every person he knew. Batman had went to the Justice League, and Oracle had searched high and low for someone, anyone, who could travel the multiverse. Jason had even exhausted his network of villains. For all the superpowered and magical beings in the world, no one could find anyone who could take Mark back home.
And yet, that was ok. It was starting to become harder to accept that he might leave rather than he might never leave. Anytime Dick said he might have a new lead (which always turned out to be fruitless), your heart caught in your throat.
Mark was… different than anyone you knew. He had a simple kindness about him, despite his scarred past. He eventually opened up and shared the horrors he had been through, including killing the man who had brought him here, and it only made you feel more drawn to him. Just as much as you wanted to learn about him, he wanted to learn about you.
The two of you had formed a routine. When Dick was off fighting crime, you’d make dinner together, eat, and watch TV. He asked about your life, your interests, your family, your hobbies. He was just as happy to talk about you as he was to talk about anything else. It was impossible not to grow close to him.
Thankfully, so did Dick. Once he was fully convinced Mark really was who he said he was, Dick was on-board with helping him. They realized they probably weren’t alternate versions of each other, considering their vastly different backgrounds, but Dick was already committed to helping him. They bonded over being superheroes, and that kind of bond is unbreakable.
The three of you created a comfortable little life together. One filled with domesticity and comfort. Mark’s arrival hadn’t changed your life too drastically, he just added an extra source of joy. That is, until you changed everything.
It was a normal night like any other. The three of you were sitting on the couch, with you sandwiched between the two men. Dick’s arm hung around your shoulder, while Mark’s knee rested against yours. But, something felt different. A primal hunger gnawed at your core. Since Mark had arrived, you and Dick hadn’t gotten any alone time, and it was finally catching up to you.
Underneath the blanket, Dick’s hand softly stroked your thigh, each movement only serving to make you needier. Mark’s hand just barely touched your hip, and the slight distance felt suffocating. As subtly as you could, you swung your leg over Dick’s, opening yourself up to him. His hand slowly climbed higher and higher, until it reached where your leg and hip met. A small murmur escaped you, and you nuzzled your head against Dick’s neck. His thumb toyed with the hem of your underwear. You pressed kisses up his neck until you reached his earlobe and gently nipped at it.
“I want you,” you whispered into his ear, voice betraying your desperation. With your hand on his chest, you could feel his heartbeat speed up. “Then why don’t we go..?” You shook your head against him, making him trail off. As much as you wanted Dick, the warm presence on the other side of you was just as enticing. Maybe it was from the lack of sex for so long, maybe it was from growing so close to him. Whichever it was didn’t really matter to you. All that mattered was that you satiated your body’s desires.
Dick’s hand froze. When he didn’t respond, you pulled back and looked up at him. His expression was unreadable. The weight of what you had just said started to sink in.
“Sorry, do you guys want me to leave you alone or..?” Mark asked, noticing how obvious you two were being. He started to move away from you, and your hand shot out to grab his thigh. Still staring at your boyfriend, you silently pleaded with him.
Dick swallowed, hard, before looking at Mark. “Do you like her?”
“What?” You turned towards Mark when he spoke, catching his eye. His face softened from confusion into affection. “I mean, yeah, of course, she - and you - have been so kind, of course-“
“No, I mean, do you like her?” Dick pressed him. His voice was rough, and you couldn’t quite tell where he was going with this. Mark just stammered, mouth opening and closing with no words coming out, eyes darting between you and Dick.
In one move, Dick moved back on the couch so he was parallel to it and pulled you back against his chest. He shoved the blanket covering you to the ground, leaving your spread legs on display for Mark. “Tell him what you told me, babe,” he said.
Your words came out a little breathless. Your heart pounded with adrenaline, a mix of desire and anxiety. The longer Mark went without answering Dick’s question, the worse it got. You could be ruining everything, but the risk was worth it if his answer was yes, if you could have them both together.
After what felt like an eternity, Mark finally asked. “Yeah. I do.” He locked eyes with you and moved closer, resting his hands on your thighs. Your breath hitched in your throat. Tingles danced across your skin.
With that, Dick’s hand dove into your underwear. You gasped, finally getting what you wanted, and Mark captured it with a kiss. His lips were warm and soft, and you moaned into his mouth. Dick trailed kisses down your neck and shoulder, nipping and sucking at your skin. His fingers slid through your folds, working you up, until he stopped on your clit. Mark massaged and squeezed at your thighs, keeping your legs open while Dick pleasured you. Each swirl of his fingers made you tremble against him. You reached one arm back to hold on to Dick’s shirt while your other arm wrapped around Mark’s neck.
The hunger inside of you was finally being fed. The two men worshipped your body, pleasuring you however the could. Mark pulled your underwear away, exposing your pussy to the cool air, while Dick’s hand slid up your shirt to grope at your breast. Two fingers settled around your nipple, rubbing and pinching at it. The multitude of sensations coursing through your body was becoming pleasantly overwhelming. Your hand tangled in Mark’s soft hair as you moaned into him.
“Ohh, God, fuck, I’m gonna-“ you sputtered between kisses. The coil in your core was getting tighter and tighter. Mark’s pushed against your thighs, preventing you from closing them as you got closer to your peak. Dick pinched your nipple a little harder, and the coil snapped. Your head fell back against his shoulder, eyes rolling to the back of your head. Liquid dribbled down your folds as you came. Right as you started to come down from your high, Mark scooped you up and picked you up off the couch.
Dick followed, discarding his clothes as Mark carried you into the bedroom and deposited you on the bed. While Mark undressed himself, Dick took the opening to pull your clothes off. You laid on the bed, fully naked, with the two men standing on either side of you. Excitement rushed through your body.
“Come here,” Dick instructed, stroking his length. You obeyed, and shifted to your hands and knees to crawl over to him. Behind you, Mark ran his hands over your bare skin before leaning down to trail kisses down your back. Dick held your chin in free hand and brought his stiff cock closer to you. Looking up at him, you flicked your tongue at its pink head. You wrapped your lips around him, sucking and swirling your tongue around his tip. Precum leaked into your mouth. Dick placed his hand on your head as he groaned.
Mark’s fingers dug into your ass. His lips sucked and nibbled at the inside of your thigh, and you whimpered into Dick’s cock. A low moan escaped him as he took over and pushed his whole length into your mouth. Tears sprung to your eyes at his tip hitting the back of your throat. Right at the same time, Mark’s lips landed between your legs. His tongue skimmed up and down your folds, making you moan and tremble. You tried to focus on pleasuring Dick. Saliva surrounded his cock as your cheeks hollowed, sucking at his hard shaft.
The tip of Mark’s tongue found your clit. He flicked at it before swirling around your now-swollen nub, sending shockwaves through your core. Dick thrusted into your moans, spit and precum dribbling down your chin. “Look at me,” he commanded. You struggled to comply, eyelids fluttering in pleasure. Seeing you struggling to hold on, with swollen and sloppy, only fueled him more. He rutted into your mouth even faster, and you reached out to hold on to his thighs, nails digging into his skin. Two fingers slipped into your slick hole and spread, stretching you out. You sputtered around Dick’s cock, gagging on your moans. Mark’s fingers pushed as deep into you, as far as they could go, filling you from both ends.
With Dick thrusting into your mouth, Mark’s tongue around you clit, and his fingers pumping into you, the shockwaves coursing through you were becoming overwhelming. Any way you tried to move away and release some of the tension, you just fucked yourself on one of them even more. The head of Dick’s cock pounded into the back of your throat over and over again while Mark’s fingers pressed into your sweet spot. Your body stilled, colored dots crossing your vision, walls tightening around Mark’s fingers. The world around you shattered, leaving only the feeling of being doubly fucked.
Your deep moans reverberated against Dick’s cock. “F-fuck,” Dick groaned, his movements going sloppier. Mark mercifully removed his fingers, opting to lap up your juices instead. “You taste so fucking good,” he murmured against you. The heat in your body rose to your cheeks.
You could feel Dick throbbing in your mouth. Free from the extra stimulation, you hollowed your cheeks and sucked as tight as you could. “Christ, I-I’m gonna, I’m gonna-“ the sound of Dick crying out your name filled the room. The tip of his cock slammed into a deep part of your throat, and warm, salty ropes of cum spilled into you. Dick pressed your face against him, giving you no release and forcing you to swallow. When he finally pulled away, you looked up at him dumbly, slightly light headed. Drool dribbled from your slack-jawed lips.
“Don’t worry, baby. We’re not done yet.”
You couldn’t help but smile up at him. He leaned down and kissed you, his gentle lips feeling slightly bruising against your swollen ones. Behind you, you heard the bed creak and the sound of fabric moving. Dick pulled away to settle on the bed, leaning back against the headboard and taking you with him. His one hand held your chin while his other stroked himself, the tip of his cock just hitting your stomach. He kept your face level with his, forcing you up on your knees and keeping your legs open.
Something soft yet firm pressed against your entrance. Mark’s arms wrapped around you, one hand holding your hip, the other groping your breath. “You still want this?” he murmured into your ear. His warm breath against your skin sent tingles down your spine. “Yes,” you gasped, never breaking eye contact with Dick.
Mark pushed into you, stretching your hole out even further and drawing more gasps and moans from you. He pumped into you slowly, letting you adjust to his size. “Fuck, you feel so good,” he groaned, his pace picking up. Dick gripped your chin, forcing you to look into his eyes while Mark fucked you.
“That feel good, baby?” Dick teased. His blue eyes twinkled with affection, dark and seductive as they were.
“..‘mph, y-yes,” you managed to get out. Mark’s thrusts speed up as he got lost in your tightness. Strangled mewls and moans poured out of you. The sound of him pounding into your slick cunt, balls smacking against your ass, mixed with him moaning your name. He jackhammered into you faster than humanly possible, threatening to shatter you completely.
“F-fuck, ‘mph, Di-Mark!” you cried out, colored dots crossing your vision, the world around you crumbling. Your guts tightened and your body stilled as you completely shattered around Mark’s cock. “Christ, that feels so fucking good,” Mark gasped behind you, his voice strangled. He fucked you through your orgasm, slamming deep inside of you. With one last powerful thrust, he hit deeper than ever before, and emptied himself inside you.
He rocked against you, letting his cum coat your walls. When he finally pulled out, you collapsed forward onto Dick’s chest. But before you could catch your shaking breath, he grabbed your hips and spun you around. “My turn,” he practically growled before lowering you onto his cock. His familiar length filled you fully, slightly longer than Mark’s, but mercifully not as thick. A strangled groan escaped you, your pussy slightly sore now. “Go on, baby, fuck yourself on me.” You tried to obey, but your shaking legs barely let you lift up.
Mark crawled forward and slotted himself between your thighs. “You’re so beautiful,” he murmured, leaning forward to kiss you. He moved with you, his hand holding the back of your head to keep your lips on him. His other hand caressed your thigh, slowly moving towards your core. His thumb landed on your swollen nub, and your movements faltered as he swirled his thumb on it.
Noticing you slowing down, Dick took over. He lifted you up and down, slamming you down on his cock, using your body like a fleshlight. You cried out into Mark’s mouth, and your arms shot out to wrap around his neck. Dick’s head fell to your shoulder. His teeth dug into you as he sucked at your skin. Mark moved off your lips, letting your mewls and cries spill out. He trailed hot kisses down the other side of your neck, and you melted into his touch. They lavished you with kisses, worshipping your body.
Caught up in their touch, you barely even realized what was happening before the bundle of nerves at your core exploded.Your back arched forward as your eyes lulled back in your head. Your walls spasmed around Dick, squirt spilling over Mark’s hand, as your mind went numb. Dick buried his groans in the crook of your neck. Feeling you tighten, he picked up his pace, mercilessly slamming you up and down on his cock.
“Ohhh, Dick! F-f-fuck, I can’t, ohmygod, mph!” you cried out, fully overwhelmed. Mark’s thumb of your clit sped up, rubbing over it nearly as fast as your vibrator. His lips traveled down to your hardened nipple and he sucked it into his mouth. His teeth lightly grazed it while his tongue flicked and swirled at you.
“That feel good baby? You gonna come for me again? Make a mess all over my cock?” Dick grunted into your ear. His movements grew sloppier as he neared his peak, his fingers digging into your soft hips and haphazardly moving you up and down.
All words failed you. Only whimpering moans came out of your slack-jawed mouth. The shockwaves coursing through you took over, and you shattered around him once more. Nothing existed anymore but the feeling of their bodies against yours.
“Oh, fucking Christ,” he panted. You could feel his cock throbbing inside of you. Dick lifted his hips up to met your body, slamming into you hard once, then twice. More warm cum spilled into you. He released your hips. opting instead to gently rock up into you. Mark pulled back, releasing your nipple with a pop, and removing his hand from your pussy. You trembled in Dick’s arms, fully falling back into his chest.
“I’ll get a washcloth,” Mark said, seeing your cunt coated in cum. Dick gently lifted you off of him and your curled up in his arm, head nestled in his shoulder like usual.
“Was that what you wanted, babe?”
“Mm, yes,” you murmured against him, a blissful smile spreading across your face, “Thank you.”
Dick didn’t respond, he just chuckled softly and pressed a kiss to your forehead. When Mark returned, he pried your legs open and gently wiped away their cum. The cool, damp rag was soothing against your raw pussy. After he finished, you could feel his presence standing next to the bed, hesitating. As he started to turn to walk away, you shot your arm out to grab his and pull him into the bed.
Mark relented, relaxing into the plush mattress and wrapping his body around yours. You exhaled a content sigh, fully satisfied.
“Maybe it was a good thing I got stuck here,” Mark joked.
You and Dick both laughed, his laughter reverberating against your cheek. He wasn’t wrong, though. Warm happiness filled your chest. Sandwiched between the two Graysons, it was easy to fall into a deep, peaceful sleep.
