You hadn’t been sleeping so much as hovering at the edge of it — and when you turned and found the space beside you empty, your stomach sank. It wasn’t the first time Spencer had disappeared in the middle of the night after getting home from a tough case, but it still felt like something was missing, like the weight of him was the only thing that ever let you sleep at all.
You padded out into the living room quietly and found him exactly where you knew he’d be: sitting on the floor in front of the couch, elbows on his knees, head in his hands, fingers tugging at his curls like he might come undone if he let go.
He didn’t look up when you approached. Just sat there, legs drawn in, spine curled forward, his face lost in shadow.
You said nothing. Only sank slowly to the floor beside him, settling in shoulder-to-shoulder. Your thigh brushed his, and still, he didn’t pull away.
The silence between you stretched.
Then he exhaled — slow and quiet — like it was the first sound he’d made in hours. You turned your head just slightly, a silent invitation. He leaned into it.
His temple came to rest against your shoulder, and this time, the sigh that escaped him sounded almost like surrender. Not defeat — but relief. The kind that only comes when you realize you’re safe.
You let a beat pass before speaking, your voice barely above a whisper. “Do you want to talk about it?”
He shook his head, and you didn’t push. Just stayed with him. And when his lips found your collarbone a few moments later, you let it happen. It wasn't just out of desire — it was out of gravity. Like he was being pulled towards the only thing that made him feel alive.
He kissed up the line of your throat, slow and aching, until his mouth met yours in a deep, trembling kiss. Not lustful, not yet — just desperate. Desperate to feel. To be.
The rug was soft beneath you where you sat, and the quiet of the room wrapped around you like a second skin. Neither of you made a move to shift, not to the couch, not to the bedroom. Just this: grounded and close, where the silence felt like shelter.
Eventually, he turned to you more fully and reached up, cradling your jaw like you might vanish. His thumb brushed the corner of your mouth, reverent.
“Is this okay?” he asked softly.
“Yes,” you murmured. Then, gently, “Are you?”
His answer was a breath, not quite steady. “No. But I will be.”
He leaned back in, and the kiss turned heavier. Clothes slipped off one layer at a time, discarded in a heap against the floor, and his hands moved like he was memorizing you — knuckles grazing ribs, palms against hips, fingertips dragging slow lines along your skin.
Maybe this wasn’t the healthiest way for him to cope — reaching for you instead of talking, chasing sensation instead of sleep — but you didn’t stop him. You let him anchor himself with your body. Forgave him the impulse before he even asked.
When his mouth found your chest, he groaned low in his throat, like the taste of you was healing him. Then, against your breastbone, he murmured, “Did you know that the skin has over four million sensory receptors?”
You blinked down at him, breath caught halfway to a laugh. “Is that really what we’re talking about right now? Science facts?”
His thumb traced a lazy circle around your nipple. “It’s relevant data,” he mumbled. “Your body is a highly responsive neural system. Every time I touch you—” He pressed a kiss just beneath your sternum. “—your brain creates a cascade of dopamine, oxytocin, and serotonin. Pleasure, connection, trust.”
You stared down at him, stunned by the tenderness in his eyes. “You’re trying to make this a chemistry lesson?”
“No,” he said, voice thick. “I’m trying to tell you how good I’m about to make you feel.”
Then his fingers dipped between your thighs, slow and reverent, and your head tipped back with a gasp.
“I need you to know,” he said, voice low and wrecked, “exactly how much you affect me. Every part of me. Mind and body.”
His touch was expert but unhurried, every stroke deliberate, sacred. Then his mouth followed — lips brushing the inside of your thigh, tongue circling your clit with aching precision. His fingers kept moving inside you, slow and steady, and your hips trembled under the weight of it.
“You’re so responsive,” he murmured, mouth hot against you. “Heart rate elevated… pupils dilated… and your breath—” He sucked gently, pulling a ragged sound from your throat. “—sharp and shallow.”
“Spencer,” you gasped, clutching his curls. “You’re not helping.”
“Oh, I believe I am,” he said, voice wicked and reverent all at once.
Then, quieter: “I think about this when I’m gone. The sounds you make. The way you shake when I touch you like this.”
You whimpered, bucking into him, desperate to keep him close. “Tell me more.”
“I think about how soft you are. How you always let me take my time. How you never rush me, even when you’re falling apart.”
He watched you unravel, watched your mouth part and your eyes flutter. He whispered things to you — not facts now, but sweet, filthy things:
“I love how wet you get for me.”
“Every time I touch you, it’s like you bloom.”
“Do you know how fucking beautiful you are when you come?”
You were close — he could tell by the way your thighs trembled, by the tight, needy grind of your hips. And for a second, it felt like he might let you fall over the edge right there, coax it from you with just his fingers and his mouth and that low, aching voice.
But instead, he slowed his pace. Let you hover there, breathless and blinking. Then, deliberately, he pulled his fingers from you and slid them into his mouth with a moan.
Your body ached at the loss, hips twitching, but the look in his eyes made your breath catch.
“Not yet angel,” he murmured against your skin. “I want to feel it when you break.”
You reached for him, dragging him up your body — and he let you. Let you kiss him messy and unguarded. Let you grind against him, bare and aching, like your body was the only tether he had left.
But he didn’t enter you right away.
He hovered instead, your foreheads pressed together, his breath catching where it mingled with yours. Your spine arched beneath him, every inch of you straining toward contact. And then, finally — with a soft, broken moan — he sank into you, slow and deep.
You both gasped.
He didn’t move at first. Just stayed there, buried to the hilt, body trembling like he could shatter from the inside out. Then he began to move — careful, reverent, every thrust measured like it meant something. Like it had to.
You kissed him hard, overwhelmed. His grip tightened on your hips, his voice catching against your skin as he whispered, “I don’t deserve you.”
You hated when he said that. Hated that he still couldn’t see himself clearly.
“Yes you do,” you breathed. “You always have.”
His pace built gradually — never rough, just more. More contact, more desperation, more whispered nothings as he moved inside you like he was chasing heaven in the way your body opened for him. His forehead pressed to yours, breath catching warm between you. Every slow thrust felt like a question.
And you answered him — first with the way your body yielded, then with your voice.
“Yes,” you whispered — and in that one word, you gave him everything:
Yes, I’m here.
Yes, I want this.
Yes, you’re safe.
Yes, I love you.
He cupped your face in both hands as his hips stilled, eyes wet, voice wrecked. “You’re the only place I don’t echo.”
His thumbs swept softly along your cheeks, like he was still anchoring himself. “When I’m out there, everything I feel just ricochets around inside me. Guilt. Fear. The things I’ve seen, the things I’ve done — it’s like shouting into an echo chamber. Everything just comes back louder.”
He leaned in, pressing his forehead to yours. “But with you… it stops. The noise quiets. I don’t have to be anything but this.”
You barely had time to breathe before his lips found yours again, hungrier now, as if speaking the truth out loud had unshackled something in him. His hips shifted, his rhythm deepening, and his mouth grazed your cheek.
“You like that?” he asked, hand slipping between your bodies to stroke your clit again. “Being filled so deeply you forget everything else?”
You whimpered, and he smiled against your jaw.
Your orgasm built steadily, not sudden or sharp — but inevitable. Spencer continued on with his whispered praise, with his perfect rhythm, with the kind of touch that felt like a vow. His hand never stopped, his fingers dragging tight, wet circles with slow, devastating precision.
“Every time I’m inside you,” he murmured, thrusts slowing, “it’s like my mind pauses. Like your body was designed to hold me steady.”
You gasped his name when it hit you — the wave cresting and crashing in a swell of heat and light. Your thighs trembled around his hips as your back arched off the rug, clutching him tighter, needing him closer. And he gave it to you, groaning into your skin, the sound low and reverent.
“That’s it, angel,” he whispered, voice cracking. “Let go. Fuck—look at you. You’re so fucking perfect when you fall apart for me.”
You were still pulsing around him, still reeling, when he came with a gasp, burying himself deep as his body shook with the force of it. He held you like he was afraid he’d shatter, like if he let go, he’d lose himself entirely. One arm locked around your waist, the other tangled in your hair, pulling you tight against him as he spilled inside you with a broken, desperate sound that felt like surrender.
You both lay tangled on the rug, sweat cooling between your skin. The room smelled like sex and quiet and something else — something like relief. He was still inside you, but neither of you moved to change that.
Spencer shifted eventually, just enough to brush your hair from your face. He kissed your temple, your jaw, the delicate hollow at your shoulder. Every inch he could reach, like gratitude in the shape of a mouth.
“Hey,” you whispered, fingertips tracing the slope of his back. “You okay now?”
He didn’t answer right away. Just let out a breath and tucked his face into the crook of your neck, arms wrapped tight around your waist as if trying to fuse your bodies together. You held him just as tightly.
Eventually, he eased out of you with care. You shivered at the loss of him, and he immediately pressed a hand to your thigh, grounding you.
“Don’t move,” he murmured. Then he disappeared down the hall for a moment, returning with a warm, damp cloth. He cleaned you gently, almost reverently — his touch tender, his gaze careful not to drift too far from yours.
“Oxytocin release after sex promotes emotional regulation,” he murmured as he ran the cloth gently through your folds. “Which is a long-winded way of saying… Yeah, I feel human again. And also, I love you.”
He helped you sit up slowly, then reached for your shirt and eased it gently over your head. Found your underwear next and slid them up your legs with quiet care, pausing to press a lingering kiss to your hipbone. Only then did he pull on his own boxers and flannel pajama pants, looking tousled and sleepy and utterly yours.
“Come on,” you said, reaching for his hand. “Let’s get back into bed.”
The bedroom was quiet and dim, moonlight pooling softly across the sheets. You pulled back the covers and slipped in first, expecting him to slide in on his side behind you like always.
But instead, he lay on his back and opened his arms.
You didn’t hesitate. You climbed over him, settling half on his chest, half beside him, one leg draped loosely over his hip. He folded himself around you instinctively — one arm wrapped firm across your back, the other reaching for your hand. He threaded your fingers together and pressed them to his sternum like he needed the contact to breathe.
“I know I don’t say it enough,” he whispered into your hair. “But this — you — you always bring me back.”
You tilted your face to his throat and kissed the pulse there, steady and calm beneath your mouth. “That’s all I’ve ever wanted. To be the one who quiets the noise.”
He didn’t respond with words. Just held you tighter.
A hush settled over the room, warm and thick. You felt his breathing slow, his muscles soften beneath your weight, like the echo chamber inside him had finally gone quiet.
And when he finally drifted off, wrapped around you safely, his breath rose and fell in perfect rhythm — the sound of peace, at last.
