Persuading my reserved stepsister during our break and introducing her to my manhood

During our break, my stepsister and I found ourselves alone. She's the reserved type, but I knew she had a wild side. I decided to test her boundaries by showing her my big cock. She was surprised at first, but soon her eyes lit up with desire. I could see she wanted to touch it, so I let her. She slowly reached out, her fingers grazing my shaft through my pants. It was a sight to behold - this reserved Latina babe exploring my manhood. I quickly stripped down, revealing my hard cock. She eagerly took it in her mouth, surprising me with her skills. We soon moved to the bed, where she eagerly spread her legs for me. I took her from behind, her big ass bouncing as I pounded her. Her moans filled the room as I fucked her hard. It was a wild encounter, and I knew we wouldn't be able to resist each other again.
