The house smelled like sex and sweat the second I walked in. Mom was already on her knees in the living room, her big pregnant belly resting on the floor while Dad fed her his thick cock. Her tits hung heavy and full, milk dripping from the nipples every time she moaned. My sister Lisa sat on the couch with her own swollen belly, legs spread wide, rubbing her clit while she watched.
"Fuck, come here," Lisa said the second she saw me. "I need another load in me before the night’s over."
I dropped my pants right there.
My dick was already hard. Mom looked up from Dad’s cock, spit running down her chin, and smiled. "Get over here and fuck your sister. She’s been begging for it all afternoon."
Lisa pulled me between her thighs. Her pussy was soaked, lips puffy and open. I shoved my cock straight into her without any teasing, bottoming out in one thrust. She grunted and grabbed my ass, pulling me deeper. "Harder. Knock me up again if you can."
Dad pulled out of Mom’s mouth and moved behind her. He slapped her ass and drove into her from behind, making her heavy tits swing and leak milk onto the carpet. The wet sounds of his balls slapping against her filled the room. Mom reached over and grabbed Lisa’s hand, squeezing it while both of them got fucked.
"Fuck, your pussy’s gripping me so tight," I told Lisa, pounding her hard. Her pregnant belly jiggled with every thrust. She reached down and rubbed her clit fast, eyes locked on mine.
"Fill me up, little brother. I want to feel it leaking out of me all night."
Mom came first, moaning loud while Dad kept slamming into her. Milk sprayed from her nipples in little arcs. Dad pulled out and shot thick ropes across her ass and lower back, then rubbed it in with his cock. He wasn’t done though. He moved over to Lisa and offered his still-hard dick to her mouth. She sucked him clean without hesitation, tasting Mom’s pussy on him.
I kept fucking Lisa until I felt my balls tighten. I buried myself deep and unloaded, pumping cum straight into her pregnant cunt. She came with me, legs shaking, pussy milking every drop.
We didn’t stop there. After a few minutes of catching our breath, Mom got on the couch on all fours and told me to take her ass. Her pregnant belly hung low, and Dad held it up while I worked my cock into her tight hole. Lisa straddled Mom’s face and let her lick her freshly fucked pussy, moaning while Mom sucked my cum out of her.
Dad moved behind Lisa again and slid into her from below, so we were both fucking them at the same time, facing each other. The room was loud with skin slapping, wet sucking sounds, and dirty talk.
"Look at you two breeding your sister and mother like animals," Dad growled, thrusting up into Lisa. "Keep going. Make them both cum again."
Mom’s ass clenched around my cock as she came on my sister’s tongue. Lisa followed right after, her pussy spasming around Dad’s dick. I pulled out of Mom and shot another load across her pregnant belly, watching it mix with the milk already there. Dad did the same to Lisa, painting her swollen tits white.
We kept going for hours. Different positions, different holes, swapping back and forth. Mom rode my face while Lisa sucked me off. Dad fucked Lisa’s ass while she ate Mom’s pussy. Every time someone came, someone else was right there to lick it up or push it back inside.
By the end of the night the whole room reeked of cum and sweat. Mom and Lisa lay side by side on the couch, bellies and tits shiny with spit, milk, and loads we’d given them. Dad and I sat back, cocks finally soft, watching them kiss slow and messy.
"Same time next week?" Mom asked, rubbing her belly.
"Wouldn’t miss it," I said.
Lisa just smiled and spread her legs again, showing off the mess still leaking out of her. "Who’s ready for round two?"
