I watched from the doorway as my wife’s brother shoved his thick cock into her. Lisa was on all fours on our bed, her ass up, face buried in the pillows while Mark gripped her hips and slammed into her pussy with hard, wet sounds. “Fuck, your cunt’s tighter than I remember,” he growled, pulling out halfway and ramming back in. Lisa moaned loud, pushing back against him.
I stood there with my own dick straining in my jeans, exactly where they told me to stay. Mark glanced over his shoulder and smirked. “You like watching your wife take her brother’s cock, don’t you, cuck?”
“Yeah,” I said, voice rough. My hand pressed against my bulge but I didn’t pull it out yet. That was the rule tonight.
Lisa lifted her head, hair sticking to her sweaty face. “Tell him how much you love it, baby. Tell Mark you want him to fill me up.”
I swallowed. “I want him to come inside you. Breed my wife’s pussy like I can’t.”
Mark laughed low and fucked her harder, the slap of skin loud in the room. Lisa’s tits swung under her with every thrust. She reached back and spread her ass cheeks wider for him. “Deeper, big brother. Stretch me out while my husband watches.”
Mark leaned over her back, one hand sliding under to rub her clit. “You hear that, little sister? Your husband’s begging me to knock you up. Think he’ll lick my load out of you after?”
“Yes,” she gasped. “He will.
He always does.”
I felt my face burn but my cock twitched harder. Mark pulled out, flipped her onto her back, and shoved her legs wide. He drove back in, balls deep, and started pounding her in long, steady strokes. Lisa’s eyes locked on mine while she took it. “Come closer,” she ordered. “Watch his cock disappear in my cunt.”
I stepped to the edge of the bed. From there I could see everything: her pussy lips stretched around his thick shaft, shiny with her juices, his heavy balls swinging as he fucked her. Lisa reached for my belt. “Take it out. Stroke while you watch.”
I unzipped and pulled my dick free. It was already leaking. I wrapped my hand around it and started slow strokes, matching Mark’s rhythm. He noticed and grinned. “Look at him, Lisa. Pathetic little cuck jerking off while his wife gets railed by real cock.”
Lisa moaned and grabbed my wrist, guiding my hand faster. “Faster, baby. Match him. Pretend you’re the one inside me.”
Mark pulled out again, this time flipping her onto her stomach and yanking her hips up. He spit on her asshole and rubbed the head of his cock against it. “Want it here too?” he asked her.
“Fuck yes,” she panted. “Both holes. Make him watch you own me.”
He worked his cock into her ass slowly at first, then buried it to the root. Lisa cried out, pushing back. “God, yes. Fill my ass, Mark.”
I stroked harder, precum dripping onto the floor. Mark reached around and fingered her pussy while he fucked her ass. “Tell your husband what you want next,” he said.
Lisa looked straight at me, eyes glassy with lust. “I want you to watch him come in my ass. Then I want you on your knees cleaning me while he fucks my pussy again.”
Mark’s pace turned brutal. The bed shook. Lisa came first, shaking and screaming into the mattress. Her ass clenched around him and he followed with a deep groan, pumping his load deep inside her. I watched every pulse, every twitch of his balls as he emptied into my wife.
When he pulled out, thick white cum leaked from her stretched hole. Lisa rolled onto her back, spread her legs, and crooked a finger at me. “Now,” she said.
I dropped to my knees between her thighs and leaned in. The smell of sex was thick. I licked her pussy first, tasting her, then moved lower to her ass, lapping up every drop of her brother’s cum that I could reach. Lisa moaned and held my head there. “Good boy. Clean your wife.”
Mark watched from the side of the bed, already stroking himself hard again. “When you’re done eating, I’m fucking her cunt while you watch up close.”
Lisa smiled down at me, fingers tightening in my hair. “And you’re going to thank him for every thrust.”
I kept licking, cock throbbing untouched between my legs, already knowing I’d do exactly what she said. The night was just starting, and they both knew I wouldn’t stop until they were finished with me.
