The house was quiet except for the low hum of the AC and the wet sounds coming from the living room. I stood in the hallway, twenty-one and home from college for the summer, cock already hard in my shorts as I watched my parents fuck on the couch like they didn't care who saw. Mom was on all fours, her big tits swinging while Dad slammed into her from behind, his thick cock stretching her pussy with every thrust. "Fuck me harder, you dirty bastard," she moaned, and he did, grunting as he slapped her ass red.
I should have turned away, but I didn't. Instead I stepped closer, and Dad looked up first, eyes locking on mine. He didn't stop pounding her. "Come here, son," he said, voice rough. "You've been jerking off thinking about this. Time to join."
Mom turned her head, lips parted, spit shining on her chin from how deep she'd been sucking him earlier. Her eyes dropped to the bulge in my shorts. "Show us that cock, baby. Let Mommy see what she's been missing."
I dropped my shorts right there. My dick sprang out, already leaking. Mom licked her lips and crawled forward on the couch until she could reach me. Her mouth was hot and wet when she took me in, tongue swirling around the head before she swallowed half my length.
Dad kept fucking her, his balls slapping her clit while she moaned around my cock.
"She's been talking about this for months," Dad growled, gripping her hips tighter. "Telling me how she wants her boy to fill her up while I watch. You gonna give her that?"
I grabbed her hair and pushed deeper, fucking her throat while Dad railed her pussy. The sounds were filthy—wet sucking, skin slapping, Mom choking and gagging but never pulling off. When I pulled out, strings of spit connected her lips to my cock. She looked wrecked already.
"Get on your back," Dad ordered her. She flipped over, spreading her legs wide, pussy glistening and swollen from his cock. "Eat her out while I fuck your ass."
The words hit me like a slap. I'd never done anything with a guy before, but my body moved anyway. I dropped between Mom's thighs and buried my face in her cunt, licking and sucking the taste of Dad's precum mixed with her juices. She tasted sweet and dirty at the same time. Behind me, Dad spat on my hole and pressed his cock against it.
"Relax, boy. Gonna stretch you open nice and slow." He pushed in, the burn sharp at first, then melting into something hot and full as he sank deeper. I groaned into Mom's pussy while he started thrusting, each stroke driving my tongue harder against her clit.
Mom came first, thighs clamping around my head, flooding my mouth as she screamed. Dad didn't stop fucking me. He reached around and stroked my cock in time with his thrusts until I was shaking. "You want to cum in her?" he asked.
I nodded, desperate. He pulled out and I climbed over Mom, sliding into her soaked pussy in one thrust. She was tighter than I expected, gripping me like she never wanted to let go. Dad moved behind me again, pushing back into my ass while I fucked her. The three of us moved together, a sweaty, grunting pile of bodies.
Mom came again, nails digging into my back. I followed right after, pumping thick ropes deep inside her while Dad filled my ass at the same time. We stayed locked together, breathing hard, cum leaking out around our cocks.
Dad pulled out first and slapped my ass. "Clean us both up," he said. Mom smiled, spreading her legs wider so I could lick my own cum from her pussy while Dad fed his softening cock into my mouth.
We didn't stop that night. We moved to the bedroom, fucked in every position, Mom riding my face while Dad fucked her, then switching so I could watch them together before they pulled me back in. By morning we were all sore, marked, and already planning the next time.
It wasn't the last night we crossed that line. It was just the first.
