My boyfriend, and my little sister all crashed in my room after a movie marathon. She fell asleep first, sprawled out on the other side of the bed, completely knocked out. The lights were dim, and the room quiet except for the sound of her breathing, and the way my boyfriend kept looking at me. I knew from that moment that he was plotting something. He didn’t say a word, just slid closer, his hand grazing mine under the blanket. I shot him a warning look, but he just smirked, that mischievous glint in his eyes making it clear he wasn’t planning to stop. “You’re crazy,” I said silently, but all he did was shrug, his fingers starting to trace on my thigh. He was doing the things that usually turn me on and make me wet. I tried to focus on the movie still playing on the TV, but it was useless. His touch was light, teasing which really drove me insane without making a sound. My heart was racing, knowing my sister was just a few feet away. The risk only made it more intense. He leaned in, his lips brushing against my ear as he whispered, “You sure you don’t want to have a little fun?”. I bit my lip, glancing at my sister, still asleep. It was risky—too risky—but the thrill was making me even hornier. Before I could overthink it, I nodded, and that was all the permission he needed. He pulled me into him, keeping everything slow. Every move was calculated, every touch soft but firm, like he knew exactly how to keep things quiet while still making me wet. We covered ourselves with my blanket, hiding the way his hands explored my body. I removed my bra after a while so he could play with my nipples without any issues. My breathing hitched, and he paused. It was on now, seeing how far we could go without waking her. And God, it was thrilling! He kissed me slowly like he was savoring the moment. He knew exactly how to mess with me, making it impossible to stay chill. I held on tight, trying not to lose it—but he wasn’t helping at all. Now we were doing a side cuddle, and I grabbed his dick guiding it towards my pussy. He was covering my mouth with his other hand while fucking me slowly to avoid waking up my sister. After a couple of minutes fucking, he increased his speed, and then my sister made a noise so we both panicked and pretended we were sleeping while his dick was still inside my pussy. The feeling of his dick inside me for a long time turned me on so much that I couldn’t wait and moved my hips. I wanted to get fucked hard, but we couldn’t do it there, so we decided to sneak to the bathroom and continue. He then turned me over and rammed his cock in my tight wet pussy while I was holding on the sink countertop. As he hits it from behind, he pulls my hair back fucking me rough making really hard for me to prevent myself from moaning. He was hitting my spot with every thrust he did while my pussy juice covered his dick. After a while, I told him to go fast and finish inside me before my sister noticed that we were not in bed. I started begging for his cum and being a slut ready to be filled. He filled up my pussy and then quickly put his clothes back on. He went outside first while I stayed seated there waiting for my legs to stop shaking.
