Secretly observing my sister's solo pleasure using a hidden camera while she watches porn on her phone

I've been keeping a secret from my family for a while now. I've got a hidden camera set up in my sister's room, and I've been using it to watch her pleasure herself while she watches porn on her phone. It's a bit taboo, I know, but the sight of my sister, a young and sexy Colombiana, touching herself is too much to resist. I've been recording all of her solo sessions, and I've got quite the collection of videos. It's not just about the sex, though. It's the thrill of the voyeuristic experience, the excitement of watching my sister's every move without her knowing. It's a bit like being a secret agent, spying on my own sister. But the real twist? She's not just any girl. She's a young and sexy prostitute, and watching her work her magic on herself is a sight to behold. So, if you're into amateur footage, hidden cameras, and taboo stuff, you're in for a treat.
