I captured a picture of my teenage step-sibling

I was going through my photo gallery when I stumbled upon a picture I had taken of my step-sister. She's 18 and has always been a seductive girl. I never thought much of it until I saw the naughty smile on her face in the photo. It was then that I realized she was up to something. I decided to confront her about it, and she didn't deny it. Instead, she showed me more explicit pictures of herself. She was trying to get my attention, and it was working. I couldn't resist her allure. We ended up in the bedroom, and I had sex with her. It was a wild experience, and I couldn't get enough. I took her from behind, and she moaned in pleasure. Finally, I released my load inside her, and we both enjoyed it.
