The sound of the alarm startled you, drawing you out of a deep sleep. You snuggled closer to the warm body wrapped around you, burying your nose against his chest. He reached over you, squishing you beneath him.
"Sam," you grunted. "I can't breath." You put both hands on his chest and pushed, trying to get him off of you.
"Sorry," he mumbled. He grabbed his phone, silenced the alarm, then dropped it back to the bedside table. He leaned over you, pressed a kiss to your forehead and sat up, somehow managing to crawl over you without suffocating you.
You burrowed deeper under the covers, pulling them over your head. "Where are you going?" you asked.
"I need coffee," he yawned.
"M'kay," you hummed, your eyes closing almost immediately.
"Lazy," Sam chuckled, pushing himself to his feet. He padded from the room, the sound of his footsteps fading slowly away.
You wanted to get up, wanted to follow him, spend those few extra quiet minutes alone with him before Dean got up and started banging around in the kitchen, grumbling about "damn people messing with my things." But it was so warm trapped here under the blankets on Sam's bed, especially on his side.You slid over and wrapped your arms around his pillow, the unmistakeable smell of Sam filling your nose.
He had left the door open a few inches when he left and you could very faintly hear the sounds of cupboards opening and closing, then you heard Dean go past the door, his stride distinctively different than his brother's. Seconds later you heard the boys talking, not what the were saying, just the cadence of their words. You dozed off, feeling comfortable and safe in Sam's bed.
God knew how long you slept before you felt the bed dip slightly and the blanket being pulled off of your face.
"Hey, that's my side of the bed," Sam laughed.
You opened one eye and tried hard to glare at him with it. "It's warm over here," you shrugged. "Not sorry." You yanked the blanket back over your head.
You heard Sam sigh, then the covers lifted and he slid into the bed, turning on his side, facing away from you. After a few minutes, you scooted across the bed and threw your arm over him, pressing your face between his shoulder blades.
Sam's breathing steadily slowed and you were sure he'd fallen asleep, until you felt his fingers lacing with yours, his thumb brushing over your knuckles. He relaxed against you, his warmth washing over you.
"Sam?" you murmured.
"Hmm?" he hummed sleepily.
"Are you asleep?" you asked.
"No," he chuckled. "Why?" He turned just slightly toward you, grinning.
You pulled your hand free of his and slipped it inside the front of his sweatpants, cupping him gently, stroking his soft cock with the tips of your fingers.
"Y/N," he groaned.
"Shh," you hushed him, shifting slightly to make yourself more comfortable, taking his rapidly hardening member fully in hand, sliding it up and down the long shaft. You swiped your thumb across the tip, pre-come already leaking from it, easing the movement of your hand.
Only a few seconds passed before Sam's breath was tearing in and out of his throat, his hips jerking as he thrust in and out of your closed fist. He put his arm across his face, covering his mouth, stifling his moans of pleasure. His head was thrown back, the muscles in his neck standing out, hard and taut as you stroked him harder and harder.
"Jesus, Y/N," he moaned, his fingers tightly wrapped in the sheet beneath him. "Baby, I'm gonna come -" He broke off with a strangled gasp as you yanked his pants down and pushed him to his back, kicking off your own pajama pants before straddling him.
You took hold of his hand, pulling it between your bodies, guiding him to the warm heat at the apex of your thighs. You moaned as his fingers slid through the wet folds, easily finding and caressing your clit as you ground down on him. You pushed his gray sleep shirt up and over his head, your own shirt joining his seconds later.
Sam sat up, pulling you with him as he did, one arm around your waist. Two long fingers slipped past your folds, working quickly to open you up. You were impatient, though, wanting to feel him inside you, so you pushed his hand away and slowly lowered yourself onto him. He rested his forehead against yours, staring into your eyes as he pushed himself inside you, inch by inch.
"Sam," you gasped, your fingers digging into his shoulders.
He moved, his hips tipping up, pushing himself deeper into you, drawing another gasp of pleasure from you. One hand tightened on your hip, the other sliding up your back to pull you snug against him. You rocked forward while he thrust up into you, both of you moving fast and hard, panting, moaning, and gasping, racing toward your mutual orgasms.
Sam lips were on your neck, biting and sucking, his hands so tight on your hip and waist that you could feel the bruises forming, but you didn't care, because this was worth every mark, every bruise. Every part of you was screaming with pleasure, every nerve, every muscle. You squeezed your eyes closed, letting the sensations wash over you as Sam's hands slid up your back, holding your shoulders, pulling you down onto him as he slammed into you, finally letting go with a loud grunt of your name. You collapsed against his chest, exhausted, but content.
Sam ran his hands up and down your back, gently kissing the top of your head. He rolled to his side, pulling you with him, holding you in his arms, the two of you cuddled close together. He sighed, a cute grin on his face. He pressed a kiss to your cheek.
He closed his eyes and took a deep breath. "Now I really need coffee," he mumbled.
