Jake had been my best friend since college, always cocky, always taking what he wanted. When he moved in with us for a few weeks after his divorce, I never expected him to take my wife too. But one hot summer night, everything changed.
It started in the living room after dinner. My wife Lisa was in a thin tank top and shorts, her tits barely contained, nipples poking out. Jake sat on the couch, legs spread, his thick bulge obvious in his jeans. I was in the armchair, pretending to watch TV, but my eyes kept drifting.
Lisa laughed at something Jake said, then stood to grab more drinks. When she bent over, Jake reached out and grabbed her ass hard, fingers digging into the soft flesh. "Damn, Lisa, that ass is begging for it," he said, voice low and rough.
She didn't pull away. Instead she pushed back into his hand. "You think so?" she asked, glancing at me with a smirk. I froze. My cock twitched in my pants even as my stomach twisted.
Jake stood up and pulled her against him, grinding his hard dick on her. "I know so. Bet your husband doesn't fuck it right." He looked straight at me. "You gonna stop me, or you gonna watch?"
I said nothing. My silence was all the permission he needed.
Jake yanked Lisa's tank top down, freeing her heavy tits. He sucked one nipple into his mouth, biting it while his hand shoved down her shorts. She was already wet; I could hear how soaked she was when his fingers slid into her pussy. "Fuck, she's dripping," he growled. "Come closer and see what a real man does to your wife."
I moved to the edge of the chair, dick rock hard and aching. Jake bent Lisa over the arm of the couch, ripped her shorts off, and slapped her ass until it glowed red. Then he dropped his pants. His cock was bigger than mine, veiny and thick, already leaking precum. He rubbed the head up and down her slit, teasing her clit.
"Beg for it," he ordered.
"Fuck me, Jake," Lisa moaned. "Show my husband how you own this pussy."
He slammed into her in one thrust. Lisa cried out, back arching as he stretched her wide. Jake fucked her hard and fast, balls slapping against her, the wet sounds filling the room. "That's it, take every inch," he grunted. "Your husband's little dick could never do this."
I pulled my own cock out and stroked it, watching my wife get pounded. Jake reached around and rubbed her clit, making her cum fast, her pussy clenching around him. He didn't stop. He flipped her onto her back, hooked her legs over his shoulders, and drove deeper. Her tits bounced with every thrust.
"Look at him jerking off while I wreck you," Jake said, grinning at me. "He loves it. Your whole family is mine now."
He pulled out and made her suck him clean, then bent her over again and took her ass.

Lisa screamed in pleasure as he worked his thick cock into her tight hole, stretching it open. He fucked her ass raw until he filled it with cum, then made her push it out so I could see it drip down her thighs.
After that night it became regular. Jake fucked Lisa every day, sometimes in our bed while I watched from the doorway. He started bringing her sister over too, turning our house into his personal fuck den. Lisa and her sister would kneel side by side, sucking his cock together, competing to swallow his load.
One afternoon he had both women bent over the kitchen table, alternating between their pussies, telling me how much better they felt than my wife ever had with me. He came inside Lisa first, then her sister, leaving them both leaking.
By the end of the month, Jake had completely taken over. Lisa stopped sleeping with me entirely. She only wanted his cock, and she made sure I knew it, moaning his name loud enough for the neighbors to hear. Jake moved out eventually, but the damage was done. My wife still calls him when she needs a real fuck, and I still watch the videos he sends me of him using her.
Our family will never be the same. And I wouldn't change a thing.
