Jake slammed the front door behind him, duffel bag hitting the floor. Three weeks home from college and the house already felt small. His dad, Mark, was in the kitchen nursing a beer. His stepmom, Lena, twenty-eight and tight as hell, leaned against the counter in a tank top that barely covered her tits.
"Welcome back, big man," Lena said, smirking. Her eyes dropped straight to his crotch.
Mark grunted something about dinner. Jake didnt answer. He walked straight over, grabbed Lena by the hips, and kissed her hard right in front of his father. She moaned into his mouth and pressed her body against him.
Mark froze. "What the fuck are you doing?"
Jake pulled back just enough to look at his dad. "What you cant. Shes been texting me since last semester. Told me how small your dick is. How she needs a real cock."
Lena laughed, low and dirty. She reached down and squeezed Jakes thickening bulge through his jeans. "Its true, Mark. Your son fucks me better than you ever did."
Marks face went red, but he didnt move. Jake shoved Lenas tank top up and sucked one nipple into his mouth, biting it until she gasped. He spun her around, bent her over the kitchen table, and yanked her shorts down. Her pussy was already wet, glistening.
"Watch this, Dad," Jake said. He dropped his pants. His cock sprang out, thick and veined, easily twice the size of his fathers. He lined up and slammed into Lena in one thrust. She cried out, gripping the table edge.
Jake fucked her hard and fast, the wet slap of skin filling the kitchen. Every time he bottomed out, Lena moaned louder. "God, yes, Jake, wreck that pussy. Your dad never could."
Mark stayed rooted to his chair, cock tenting his pants despite the humiliation. Jake reached around and rubbed Lenas clit while he pounded her. She came fast, legs shaking, juices running down her thighs.
Jake didnt stop. He pulled out, flipped her onto her back on the table, and shoved back in. "Tell him whose cum you want," he ordered.
"Yours," Lena panted. "Fill me up, Jake. Breed your stepmom while your dad watches."
Jake groaned and unloaded deep inside her, pulse after pulse of hot cum flooding her cunt. When he pulled out, thick white cream leaked from her stretched hole. He looked at his dad. "Clean her up."
Mark hesitated only a second before dropping to his knees and burying his face between Lenas legs, licking his sons load out of her.
That was only the beginning. Over the next week Jake took Lena everywhereon the couch while Mark sat across from them, in the shower with the door open, even in his parents bed. Every time he made sure his dad saw or heard. Lena got louder on purpose, begging for Jakes cock, calling Mark useless.
One night Jake invited his older sisters ex-boyfriend over, but that was just cover. The real show was Lena riding Jake reverse cowgirl on the living room floor while Mark jerked off in the corner like the cuck he was. Lenas tits bounced, her pussy gripping Jakes shaft, and she kept eye contact with Mark the whole time.
"Look how deep he goes," she taunted. "Your son owns this pussy now."
Jake came inside her again, then made Mark crawl over and suck the cum off his cock while Lena watched and fingered herself. The taste of his own wifes juices mixed with his sons spunk made Mark shoot all over the floor.
By the end of break, the house rules had changed. Lena slept in Jakes room. Mark slept on the couch.

Every morning Jake woke her up with his cock in her mouth or her ass. Every night he fucked her until she screamed his name.
On the last night before he went back to school, Jake had them both on the bed. Lena on all fours, Mark on his back underneath so he could watch Jakes cock slide in and out of her from inches away. Jake fucked her slow and deep, making sure Mark saw every inch stretch her open.
When Jake finally pulled out and painted Lenas ass and Marks face with thick ropes of cum, no one spoke. They didnt need to. The student had come home and taken exactly what he wantedhis family, broken and used, exactly the way they craved.
