Secretly watching my stepsister Grace's shower routine with revealing tan lines

I've always been a bit of a voyeur, and my stepsister Grace is no exception. Every time she's in the shower, I can't help but watch her from the closet. I've got a hidden camera set up just for her, and I've been using it to capture her shower routine. It's not like she's done anything wrong, but I just can't resist watching her. She's always completely naked in the shower, and I've managed to get some great shots of her. She's got a nice tan, and her small tits are just begging to be stared at. I've got a whole collection of these videos, and I'm always on the lookout for more. It's kind of like a hobby for me, but I can't imagine not doing it. I don't think she knows I'm watching her, but I kind of hope she does. It just adds to the thrill, you know?.
