Secretly watching my plump step-sister pleasure herself

Indulging in a bit of voyeuristic pleasure, I've been secretly filming my voluptuous step-sister whenever she's alone. Her ample curves and luscious legs are a sight to behold, especially when she's indulging in her own pleasure. Day in, day out, I'm treated to the sight of her chubby form, her soft skin glistening as she masturbates. The thrill of the forbidden only adds to the allure, as I watch her intimate moments from a hidden camera. Her moans fill the room, echoing through the house as she brings herself to climax. It's a tantalizing dance of self-pleasure, a private show just for me. The thrill of the hidden cam adds an extra layer of excitement, as I watch her fat, chubby body writhe in ecstasy. It's a taboo pleasure, a secret shared only between us. But as the camera rolls, capturing her every move, I can't help but smile. This is my secret, my little vice, and I wouldn't have it any other way.
