I walked into my sister’s room, her perfect tits bouncing gently under her tight top as she sat on the edge of her bed. She looked up at me and gave me that innocent smile that drove me wild. I couldn’t help but stare at her juicy ass peeking out from beneath those tight shorts.
“Hey, stepbro,” she said softly. “Can you help me with something?”
My heart began to race as I took a seat next to her. What was she up to? Whatever it was, I knew it would be naughty as hell.
“Sure, sis. What do you need?”
She bit her bottom lip nervously before whispering, “I want you to fuck me in the ass.”
The words sent shockwaves through my entire body. My dick immediately sprung to attention inside my jeans. I couldn’t believe what I’d just heard. But damn if it didn’t turn me on more than anything else ever had before.
Without saying a word, I pulled off my shirt and reached for her waistband. In one swift motion, her shorts were around her ankles and I was admiring her perfectly plump ass cheeks. She gasped as I ran my tongue along her crack, tasting her sweetness. I stood up and yanked off my pants, freeing my throbbing cock. Without hesitation, I positioned myself behind her and slowly pushed my dick against her tight hole. She let out a loud moan as I eased my way in, inch by inch. Her ass felt tighter than any cunt I’d ever been in before. I gripped her hips firmly and began to fuck her hard, slamming into her relentlessly. She cried out with pleasure, digging her nails into the bedsheets below her.
“Fuck me harder, stepbro!” she shouted, completely losing herself in the moment. “Make me your dirty little slut!”
The words sbabble me on even more. I pounded into her with all my strength, feeling my balls slapping against her skin with every thrust. The room was filled with the sounds of our bodies slamming together and the lewd noises she made as I fucked her senseless. I could feel myself getting close to the edge. My breathing grew ragged and my heart raced in my chest. I knew I wasn’t going to last much longer.
“I’m gonna cum,” I growled, pulling her hair back so I could see her face as I did it. “You ready for my sperm, sis?”
She nodded eagerly, moaning loudly. “Give it to me, fucker! Fill my ass with your hot load!”
With one final thrust, I ejaculated deep inside her, filling her up with my cum. She screamed out in ecstasy, her body trembling with pleasure as she came too. We both collapsed onto the bed, exhausted but satisfied.
“That was fucking amazing,” I panted, running my hand through my sweaty hair.
“Yeah, it sure was,” she giggled, cuddling up to me. “Let’s do it again sometime.”
We laughed and kissed, knowing that this wouldn’t be the last time we indulged in such dirty, taboo fun. After all, family secrets are meant to be shared, especially when they involve so much pleasure.
