Valentina Jewels, my incredibly sexy 22-year-old stepsister, had been driving me crazy for months. Her long, curly brown hair, sparkling green eyes, and voluptuous figure were impossible to ignore. She had the most amazing ass I’d ever seen, perfect for family sex, and I couldn’t help but stare at it whenever she was around.
One day, I came home from work to find her working out in our shared gym. She was wearing tiny booty shorts and a sports bra that showed off her incredible curves. I couldn’t take my eyes off her.
“Hey, Valentina,” I said, trying to sound casual.
“Hey, what’s up?” she replied, not even looking at me.
“I, uh, was just wondering if you wanted to work out together, stepsister and stepbrother” I said, feeling like an idiot.
“Sure, why not?” she said, finally looking up at me.
We started working out together, but I couldn’t focus on anything except her big ass. I couldn’t take it any longer. I walked up behind her and started rubbing her hips.
“What are you doing?” she asked, sounding surprised.
“I can’t help myself,” I said, sliding her shorts to the side and touching her wet pussy.
She gasped as I started playing with her clit. I could feel her getting wetter and wetter.
“Oh my god, don’t stop,” she moaned.
I bent her over the bench and started fucking her from behind like in a video from the pervy family page. She was so tight and wet. I couldn’t get enough.
“Fuck me harder,” she begged.
I grabbed her hips and started pounding her harder and harder. She was moaning and screaming, begging for more.
“I’m gonna cum,” she cried out.
I could feel her pussy clenching around my cock as she came. I pulled out and started cumming all over her ass.
“Oh my god, that was amazing,” she said, collapsing on the bench.
We lay there for a few minutes, trying to catch our breath.
“I’ve wanted to do that for so long,” I said, finally breaking the silence.
“Me too,” she replied, smiling at me.
We started working out together more often, and our workouts always ended with us having mind-blowing sex. We tried every position imaginable, but my favorite was when she rode me reverse cowgirl. I could see her amazing ass bouncing up and down as she fucked me.
“Oh my god, I’m gonna cum again,” she cried out, grinding her hips against me.
“Cum for me, baby,” I said, grabbing her hips and thrusting up into her.
She came hard, screaming my name. I couldn’t hold back any longer. I grabbed her hips and pulled her down onto my cock, cumming deep inside her.
“That family sex was amazing,” she said, collapsing on top of me.
We lay there for a few minutes, catching our breath and basking in the afterglow.
“I love you,” I said, looking into her eyes.
“I love you too,” she replied, kissing me deeply.
We spent the rest of the day in bed, making love and talking about our future together. We knew we had something special, and we were determined to make it work.
