Mijn stiefzusjes hebben een geheime obsessie voor mijn mannelijkheid - taboe-ontmoeting

My stepsister has always been a bit of a mystery to me. She keeps to herself most of the time, but there's something about her that I can't quite put my finger on. It's not just her small tits or her cute face, it's something deeper, something darker. Something that makes me wonder if she's hiding a wild side. The other day, I caught her sneaking around my room, staring at my cock. I didn't know what to make of it at first, but then she started sucking it like a vacuum cleaner. It was the weirdest thing I'd ever seen, and it made me feel kinda gross. But at the same time, it was kind of hot too. After that, we started messing around more and more. She rides me like a cowgirl, bouncing up and down on my hard cock. It's not exactly the kind of sex I'm used to, but it's definitely getting me off. And I have a feeling it's getting her off too.
