After school lesson turns into a steamy encounter with my stepbrother's big dick

After a long day at school, I was eager to catch up with my stepbrother. As we sat down for our after-school study session, things took an unexpected turn. His eyes kept wandering below my shirt, igniting a spark of desire between us. Before I knew it, he had his hands under my shirt, exploring my body. The heat between us was undeniable, and it was clear that he was well-endowed. His big dick was hard and ready for action. I couldn't resist the urge to ride him, and so I straddled him, feeling his massive cock penetrate my tight hole. The room was filled with moans and the sound of our bodies moving in perfect rhythm. The pleasure was overwhelming, and I found myself lost in the ecstasy of the moment. This was a lesson I was sure to remember.
