I walked into the kitchen and saw my stepmom bent over the counter in nothing but an apron, her ass cheeks spread wide as she reached for something in the fridge. "Took you long enough," she said without turning around. "Your stepsister's already dripping in the living room. Free use means you take what you want, when you want it. Get over here and fuck me first."
My cock was already hard. I dropped my shorts, grabbed her hips, and slammed into her pussy in one thrust. She was soaked, tight around my shaft, and she moaned like a slut as I pounded her from behind. "That's it, use that stepmom cunt," she grunted, pushing back to meet every stroke. Her tits swung under the apron with each slap of my balls against her. I reached around and rubbed her clit hard until she came, her walls clenching and gushing around me.
I didn't pull out. I kept fucking her through it, raw and deep, until I unloaded inside her, filling her up with thick ropes of cum. She stayed bent over, letting it drip down her thighs. "Good boy. Now go find your stepsister. She's been waiting all morning with her legs open."
In the living room, my stepsister was on the couch, legs spread, fingers buried in her shaved pussy. She looked up and grinned.
"Heard you just creamed Mom. My turn. Come stick that dick in me while it's still wet." She didn't wait. She pulled me down and straddled me, sinking onto my cock in one smooth motion. Her tits bounced as she rode me hard, grinding her clit against my pelvis. "Fuck, your stepdick feels so good stretching me," she panted. I grabbed her ass and thrust up to meet her, slapping her cheeks red while she bounced.
She leaned forward so I could suck her nipples, biting them just hard enough to make her yelp. Then she flipped around, reverse cowgirl, and I watched my cock disappear into her ass as she took it there instead. "Deeper, fuck my ass raw," she demanded. I held her hips and drove up into her, pounding that tight hole until she squirted all over my balls. I followed right after, pumping another load deep in her ass.
We didn't stop there. The day turned into a blur of free use. Later I found them both in the shower, soaping each other up. I joined in, pushing my stepsister against the wall and fucking her from behind while she ate my stepmom's pussy. Then they switched, my stepmom on her knees sucking my cock clean before riding me on the shower floor. Cum and water mixed on the tiles as we kept going, switching holes and positions without asking.
By evening they had me on the bed, taking turns. My stepsister sat on my face while my stepmom milked my cock with her pussy, then her mouth. "Swallow every drop," she ordered when I came down her throat. They didn't let me rest. My stepsister climbed on next, grinding her cum-filled cunt on my tongue while they made out above me.
We kept at it until late, bodies slick with sweat and cum, every hole used and dripping. They made the rules clear: anytime, anywhere, no questions. I woke up the next morning with my stepsister's mouth already wrapped around my morning wood and my stepmom's fingers teasing my balls. "Round two starts now," she whispered. "Free use family means you never stop fucking us."
The whole weekend blurred into the same filthy rhythm. I bent them over furniture, fucked them in the car, took my stepsister in the backyard while my stepmom watched and fingered herself. They begged for it dirty and raw, calling out for more cum in their pussies and asses. By Sunday night we were all spent but satisfied, already planning the next round. In this house, free step family sex stories weren't just talk. They were the new normal, and I was ready to keep using every inch of them.
