I assist my stepsister with her studies while she flirts with me in a provocative dress - complete narrative

I was at my stepsister's place, assisting her with her studies when she decided to wear a rather provocative dress. The dress hugged her curves perfectly, accentuating her ample assets. I found myself unable to resist the allure, and before I knew it, I was teasing her, leading to a heated exchange of dirty talk. As the tension built up, we found ourselves in a compromising situation, with me unable to resist the urge to explore her further. With her consent, I began to touch her, my hands exploring every inch of her body. The sight of her beautiful face, flushed with desire, was too much to resist. I plunged my throbbing member into her eager mouth, watching as she skillfully took me in deeper. The sight of her chubby body moving on top of me was a sight to behold. As we reached our climax, I released my load into her waiting mouth, marking the end of our passionate encounter.
