Naughty stepsister becomes aroused while observing my exercise and demands anal intercourse

My innocent stepsister, a college student from Colombia, has always been a bit of a wild child. She loves to watch me work out, and the other day, she got a little too excited. As I was doing my thing, she couldn't resist reaching down and touching herself through her pants. When I caught her, she was shocked but also aroused. She begged me to take her right then and there, and I couldn't resist her pleading eyes. She dropped to her knees and took my hard cock into her mouth, giving me a deepthroat blowjob like I've never seen before. But it wasn't enough for her. She wanted more, and she craved it in her tight ass. I had to oblige, taking her from behind while my mom walked in on us, adding an extra layer of taboo to our encounter. It was a wild ride, but one that left us both breathless and satisfied.
