Caught browsing porn with my step sister in a compromising position

I was at my place, scrolling through my phone when my step sister walked in and caught me in a compromising position. She had a stern look on her face, but I could see the hint of something else in her eyes. It was like she was turned on by the fact that I was looking at something that wasn't suitable for her age. She was a bit of a weirdo, but she had a nice ass. I couldn't resist. I told her to get on her knees and bend over for me. She did as I asked and I fucked her hard. She screamed and moaned as I pounded her. It was a weird feeling, fucking my step sister, but it was also kind of hot. I came inside her and I could see the satisfaction on her face. It was a weird situation, but it was also kind of fun.
