I never planned for it to happen, but once the whole family got into the incest sex, there was no stopping. Mom, Dad, my sister Lisa who just turned nineteen, and me at twenty-one we all fucking loved it. It started one sticky summer night when the AC broke and we were all lounging around half-naked in the living room. Mom's big tits were spilling out of her tank top, Dad's cock was half-hard in his boxers from the heat, and Lisa kept shifting on the couch with her shorts riding up her ass.
Dad was the one who said it first. "Fuck it, we're all adults. Why pretend we don't notice each other?" Mom laughed but her nipples got hard right away. Lisa looked at me and licked her lips. I was already stroking myself through my shorts when Mom crawled over and pulled my cock out. "You've got a nice one, baby," she said, wrapping her lips around it and sucking like she was starving. Dad moved behind her, yanking her shorts down and slamming his dick into her pussy while she moaned around my shaft. Lisa didn't wait she stripped and sat on my face, grinding her wet cunt on my tongue while I licked her clit raw.
We didn't stop that night. Mom rode me next, her heavy tits bouncing in my face while Dad fucked Lisa from behind on the floor beside us. "That's it, take your daddy's cock," Mom growled at Lisa, and Lisa came hard, screaming and squirting on the rug. Dad pulled out and shot his load across Lisa's back, then Mom made me eat it off her while she fingered herself to another orgasm. By morning we were all sticky and spent, but nobody wanted to stop.
After that it became normal. Breakfast turned into Mom sucking Dad under the table while Lisa jerked me off. Evenings we piled into the big bed or stayed in the living room, bodies everywhere. I fucked Mom's ass while she ate Lisa's pussy. Dad took turns pounding both girls, filling them up and watching the cum drip out. Lisa loved when I fucked her right after Dad, her pussy sloppy and warm from his load. Mom got off on watching us, rubbing her clit and telling us how hot her incest sex family was.
One weekend we went all in. No clothes at all. We spent two days fucking in every room. Dad bent Mom over the kitchen counter and railed her while Lisa and I sixty-nined on the floor. I came in Lisa's mouth, she swallowed and then kissed Mom deep so they could share it. Later that night we tried something new Mom and Lisa on their knees side by side, Dad and I taking turns fucking their mouths and pussies. "Harder," Mom begged, "use your whole family like the sluts we are." We did. I came inside Mom while Dad filled Lisa, then we switched and did it again.
The best part was how much everyone wanted it. No guilt, just raw need. Lisa would wake me up at night climbing on my cock, whispering how she loved being her brother's fucktoy. Mom and Dad would fuck loud in their room, knowing we'd hear and join in. Sometimes it was slow and nasty long sessions where we edged each other for hours, covered in sweat and cum. Other times it was quick and dirty, like when Dad bent Lisa over the couch during a movie and I fed my dick to Mom on the armchair.
We started keeping a running tally of who came how many times each day. Mom usually won because she could come from just watching. Dad loved filling both girls back to back. Lisa got off on being the center of attention, taking two cocks at once whenever we could manage it. I just loved that everyone was into it no hiding, no shame, just constant incest sex that left us all satisfied and grinning.
By the end of that summer we were inseparable. Vacations became excuses for more privacy. Holidays turned into all-day orgies. We talked openly about what we liked: Mom wanted more anal, Dad wanted to watch the girls trib while we stroked, Lisa wanted double penetration every weekend, and I wanted to keep breeding that tight family pussy whenever they let me. Nobody said no. We just kept going, bodies tangled, moans filling the house, every hole used and every load welcomed.
It never got old. Even now, years later, one look across the dinner table and someone is on their knees or bent over. The whole family loves it, and we make sure to keep the stories coming new positions, new toys, new ways to get each other off. That's our secret, and it's the hottest fucking thing in the world.
