you liked to lounge in your parents' bed - it was cozy, much bigger than yours, and they wouldn't mind anyway, but they aren't home. your mom had called about thirty minutes ago, saying that the storm outside was so bad that her and your dad, who had gone out for lunch with your aunt and uncle, would be pulled over at a gas station for awhile until it lets up. so, you and your brother have the house all to yourselves.

speaking of, he's currently on top of you, his rings digging into your skin as he pushes your thighs up towards your chest, his hips slamming against your ass with every thrust. "fuck," he pants, his hair sticking to his forehead with sweat. it's summer, hot out, and the storm is making it muggy. plus, the air won't work because the power is out. so, the two of you are tangled together, hot and sticky from a mix of bodily fluids.

"sammy," you moan, hands gripping the headboard behind you. you know this is wrong, blah blah blah, but god, his cock feels so fucking good. "sammy, harder," you grit out, throwing your head back as he obliges. sam lets go of your thighs and clambers over you, arms on either side of your head as he starts to thrust harder, his brow furrowed, lips parted in pleasure. "oh fuck, oh god," he whimpers, the mattress creaking with his effort. "'m gonna fuckin' cum inside you," he promises. "yeah, gonna, huhh,"

you grip his biceps, feeling them flex beneath your touch, your nails digging into his skin. the rain drops fall onto the air conditioner, thunder booms, cracks of lightning briefly illuminate the room, the air is steadily filling with misty droplets that settle on the windows and mirror.

"mommy's gonna call again," you warn. mommy. he hated when you called your parents by mommy and daddy, it was childish and embarrassing to him. "shut the fuck up," he grunts. "you're so fuckin' wet, what the fuck is wrong with you?" he whines, his cock nearly slipping out of you for the fifth time now. "i'm- shit- about to cum,"

sam leans down, his head in the crook of your sweaty neck, and he nuzzles you, kissing your neck and licking the salty sweat off his lips. "gonna fuckin' knock you up," he grins against you, feeling the way you begin to fuss and try to push him off at the threat. "sam, quit it!" you say, hands pushing at his shoulders. he wraps his arms around your neck, forcing you to be cradled against his shoulder. "don' cum in me, you better not!" his hips still, and you whimper, wrapping your arms around him in return, a low whine leaving you as his hot seed spurts into you. nothing you can do now.

"nngh," he doesn't move, just lays there, collecting himself, and the two of you both feel like you're suffocating. "fuck," he whispers. "it's hot in here," he gets up off you, his cock leaving you with a squelch, and he tucks himself back into his boxers, wiping his hand on the fabric as he makes his way over to the window, pulling it up and exhaling heavily at the cool air against his skin. you climb out of bed and make your way over, settling in front of the window. "mm, that's better," you murmur.
