Jake had been my best friend since college, always crashing at our place when the parties ran late. My wife Lena and her two sisters, Mia and Tara, all lived with me in the big house we called our family harem. They were all over twenty-five, curvy, and constantly horny, sharing my bed most nights. But one weekend everything changed when Jake stayed over.
Lena was the first to crack. We were in the living room, beers flowing, when she dropped to her knees in front of Jake and pulled his cock out. "Fuck, it's bigger than Mark's," she said, licking the head before sucking him down. I sat there frozen as my wife gagged on my friend's dick, spit dripping down her chin. Jake grinned at me. "You okay with this, buddy?" I nodded, my own cock hard in my pants despite the twist in my gut.
Mia and Tara watched from the couch, fingering themselves under their skirts. "Share him," Tara moaned.
Jake stood, stripped Lena naked, and bent her over the arm of the sofa. He slammed into her pussy from behind, pounding hard while she screamed his name. "Yes, Jake, fuck me deeper than my husband ever does." I watched his balls slap against her ass, her juices coating his shaft. When he came, he pulled out and sprayed thick ropes across her back, marking her right in front of me.
That night turned into the whole weekend. Mia climbed on Jake's lap next, riding him reverse cowgirl so I could see every inch disappearing into her tight cunt. "Look at your friend stretching me," she taunted, grinding down until she squirted all over his thighs. Tara joined in, sitting on Jake's face while he ate her out, his tongue flicking her clit as she came screaming. They took turns on him for hours, leaving me to stroke myself in the corner, too turned on to stop it.
By Sunday, the harem was his. Lena woke me up by describing how Jake had fucked her in our bed while I was asleep. "He came inside me three times," she whispered, spreading her legs so I could see his cum leaking from her swollen pussy. I buried my face between her thighs and licked it out, tasting my friend's load mixed with her cream. Mia and Tara dragged Jake into the shower, soaping his cock and balls before taking turns sucking him off under the spray. Water and spit ran down their bodies as he fucked Tara against the tiles, her legs wrapped around him.
The power shift was complete. Jake started staying full time, sleeping in the master bedroom while I took the guest room. Every evening the women paraded around naked for him, offering their mouths, pussies, and asses. He had Lena on all fours one night, pounding her while Tara sat on her face. "Eat your sister's cunt while I wreck this married hole," he growled, slapping Lena's ass red. I jerked off watching from the doorway, shooting my load onto the floor as Jake filled her up again.
It became routine. Mia would text me photos of Jake's cock buried in her from behind, captioned "Wish this was you?" Tara started calling him Daddy during group sessions, begging for his cum in her ass while Lena held her cheeks open. Jake never excluded me completely; sometimes he'd let me clean the women up with my tongue after he finished, or watch up close as he stretched one of them open. The raw humiliation only made the sex hotter for all of us.
Months later the arrangement felt permanent. The family harem belonged to my friend now, and I was the one left watching, cleaning, and getting off on every filthy detail. Jake still called me buddy when he bent one of the sisters over the kitchen counter, but we both knew who ran the house. The women were louder, wetter, and more satisfied than they'd ever been with me, and I couldn't stop craving the sight of it.
