Explore his private space and admire his rear without the risk of him indulging in more

I'm not your typical guy. I've got a bit of a strange fetish, something that makes me feel a little naughty. It's not about the act itself, but more about the anticipation of it. You see, I've got a thing for forbidden fruit, specifically, my step sister. She's not just any girl, she's a tantalizing mix of Mexican and Venezuelan, a sight to behold. But it's not just her face that's irresistible, it's her rear as well. And while I wouldn't dream of going there myself, I do enjoy the thought of someone else doing so. Hence, when she's away, I can't resist exploring her private space, admiring her rear without the risk of her indulging in more. It's a thrilling experience, one that I wouldn't trade for anything.
