The basement smelled like sweat, lube, and old cum stains on the couch. I hit play on the laptop and the screen lit up with another raw gay incest clip, two brothers with massive, veiny cocks pounding each other senseless. My own dick, already half-hard in my jeans, twitched hard at the sight.
My older brother Jake walked in right then, fresh from the shower, towel barely hanging on his hips. At twenty-five he was built like a fucking tank, and when the towel slipped I saw that monster cock of his swinging free, thick as my wrist even soft. We had been sneaking around like this for months, ever since we found our dads old stash of homemade videos. The ones with him and his brother. Huge cocks ran in the family.
Fuck, you started without me again, Jake growled, dropping the towel completely. His dick started swelling fast, the fat head already shiny. He grabbed the laptop and turned up the volume so the wet slapping sounds filled the room. On screen one brother was choking on the others giant cock, spit running down his chin while he gagged.

I stripped fast, my own nine inches springing up and slapping my stomach. Jakes eyes locked on it and he licked his lips. Get on the couch, little bro. Same position as last night.
I dropped to my hands and knees, ass up, the way the bottom brother was positioned in the video. Jake knelt behind me and spread my cheeks with rough hands. He spat right on my hole, then rubbed the head of that huge cock against it, smearing pre-cum around the rim.
Watch the screen, he ordered, voice low and dirty. Watch how that guy takes his brothers fat dick. Youre gonna take every inch just like him.
He pushed in slow at first, letting me feel every thick vein stretch my ass open. The burn was perfect. On the laptop the brothers were flipping, the bigger one now slamming into the other from behind with brutal thrusts. Jake matched the rhythm, driving his cock deeper with each stroke until his heavy balls slapped against mine.
Goddamn, your hole is tight, he grunted, hands gripping my hips hard enough to bruise. Tighter than any pussy. You were made for your big brothers cock, werent you?
I moaned and pushed back, taking him to the root. The video switched to a close-up of the top brothers massive cock disappearing into a stretched hole, over and over. Jake reached around and wrapped his fist around my dick, jerking me in time with his thrusts.
We fucked like that for a long time, raw and loud, the sound of skin slapping skin mixing with the moans from the laptop. When Jake pulled out I whined, but he just flipped me onto my back and shoved my legs up to my chest. He lined up again and sank back in with one hard thrust that made my eyes roll back.
Look at me while I breed you, he demanded. His huge cock was glistening with lube and my juices, stretching me wide every time he bottomed out. Tell me whose cock you want.
Yours, I gasped. My brothers huge fucking cock. Fill me up, Jake.
He slammed harder, sweat dripping off his chest onto mine. The video was reaching its climax too, the top brother roaring as he unloaded deep inside. Jakes rhythm broke. He buried himself to the balls and I felt the hot pulses of his cum flooding my guts, thick and endless. The feeling pushed me over. My cock jerked untouched and I shot ropes across my own chest and face while Jake kept grinding, milking every drop out of himself into me.
We stayed locked together, breathing hard, the video looping back to the start. Jake leaned down and licked a stripe of my cum off my cheek, then kissed me deep and filthy, sharing the taste.
Round two in ten minutes, he muttered against my mouth, his cock already twitching inside me again. And this time were filming it for our own collection.
Outside the basement door we could hear our dads footsteps upstairs, but down here it was just us, our huge cocks, and the endless loop of family secrets playing on the screen.
