In a taboo twist, my slender stepsister assumes I'm gay due to my lack of intimacy with her. She provocatively flaunts her assets, leading to a steamy encounter, proving my heterosexuality and culminating in intense, explosive pleasure.
My slender stepsister has always had a bit of a wild streak, and I've always been a bit worried about what she might get up to. She's a beautiful girl, with big tits and a big ass that just screams for attention. But lately, she's been acting even more strangely than usual. She's been trying to seduce me, saying things like "I know you're gay," and "I bet you'd love to fuck another guy." I've never been sure what to make of it, but I've been trying to ignore it. However, the other day, when I was in the shower, she snuck in and started showering with me. At first, I thought nothing of it, but then she started rubbing her ass against mine, and I realized that she was really trying to get me to fuck her. I couldn't believe it. I mean, this is my stepsister! But I couldn't resist her sexy body, and soon we were fucking like rabbits.
