John sat in the corner of the bedroom, pants around his ankles, cock already hard and leaking as he watched his wife Lisa ride his brother Mark's thick dick. The family reunion was still going downstairs, but up here the three of them had slipped away after too many drinks and too much tension. Lisa's big tits bounced hard with every slam of her hips. She was dripping wet, juices running down Mark's shaft and soaking his balls.
"Fuck, your brother's cock feels so much bigger than yours," Lisa moaned, looking straight at John. Her voice was raw and nasty, the way she knew he liked it. "I can feel him stretching my pussy open. You like watching your wife get fucked by family, don't you, you little cuck?"
John groaned and stroked himself slower, trying not to cum too fast. Mark's hands gripped Lisa's ass, spreading her cheeks so John could see every inch disappearing inside her. Mark thrust up hard, making Lisa's whole body jolt.
"Tell him how much better it is," Mark growled, slapping her ass. The sound cracked through the room.
Lisa leaned forward, tits swinging in Mark's face as she rode him faster. "It's so much better. Your brother's dick hits places you never could. I'm gonna cum all over him while you sit there and watch like the pathetic cuck you are."
She started grinding in circles, clit rubbing against Mark's pelvis. Her moans got louder, dirtier. "Oh fuck, yes, fill me up. Breed your brother's wife right in front of him."
John's hand moved quicker on his own smaller cock. He couldn't look away from the way Lisa's pussy lips gripped Mark's shaft, shiny with her cream every time she lifted up. The humiliation burned hot in his gut and made his balls ache.
Mark flipped her onto her back without pulling out. He hooked her legs over his shoulders and started pounding deep, the bed frame slamming against the wall. Lisa screamed with pleasure, fingers digging into Mark's back.
"Harder! Fuck me like my husband can't! Show him what a real man does to his wife!"
John watched Mark's heavy balls slap against Lisa's ass with every thrust. Sweat dripped down Mark's chest. Lisa's pussy made wet, obscene sounds as it took the pounding. She came first, body shaking, pussy clenching and squirting around Mark's cock.
"Fuck, I'm cumming! Your brother's making me squirt all over his dick!"
Mark didn't stop. He kept driving into her through the orgasm, then pulled out and flipped her onto all fours facing John. He slammed back in from behind, gripping her hips hard enough to leave marks.
"Look at your husband while I fuck you," Mark ordered.
Lisa locked eyes with John, mouth open, tongue out like a slut. "Watch him breed me. Watch your brother pump his load deep in your wife's cunt."
Mark grunted and buried himself to the hilt. His cock pulsed visibly as he unloaded, thick ropes of cum flooding Lisa's pussy. Some leaked out around his shaft, running down her thighs. Lisa moaned the whole time, pushing back to take every drop.
When Mark finally pulled out, cum poured from her stretched hole. Lisa reached back and scooped some onto her fingers, then licked them clean while staring at John.
"Your turn, cuck," she said, voice husky.
"Clean me up while I tell you how much better his cum tastes."
John crawled forward on his knees, cock throbbing untouched. He buried his face between Lisa's legs and started licking Mark's thick load out of her well-fucked pussy. The taste was salty and strong. Lisa held his head there, grinding against his tongue.
"That's it. Eat your brother's cum out of your wife's pussy. This is what you get for being such a weak little cuckold."
Mark watched from the side, already stroking himself hard again. "Round two in a minute. I'm gonna fuck her ass while you watch this time."
Lisa laughed, low and filthy, already pushing John's face deeper. "Hear that, baby? Your brother's not done with your wife yet. And neither is the rest of the family reunion if we feel like it."
John kept licking, cock twitching, lost in the raw, dirty heat of it. The night was just getting started.
