My step sister initiated sex with me at night

I was in my step sister's room late at night when she suddenly initiated sex with me. I was taken aback, but I couldn't resist her seductive advances. She started by teasingly touching herself, her fingers dancing over her petite body. I couldn't help but get aroused as I watched her. She then turned around and asked me to touch her, which I did, my fingers exploring her soft skin. After some more teasing, she finally took off her clothes, revealing her perfect body. I couldn't resist any longer and started to finger her, my fingers going deeper and deeper inside her. She moaned in pleasure, her body writhing under my touch. I then took her from behind, my throbbing member entering her tight hole. We fucked hard and fast, our bodies moving in rhythm, our moans filling the room. It was an unforgettable night, one that I will always cherish.
