I'm your older sister and I am stuck being your sitter, which is really annoying because all I want to do is talk to my boyfriend oh the phone. I tell you we are going to play hide and seek and when you go hide, I resume talking to him. Little do I know, you are still in the room watching me. My boyfriend and I start talking dirty and I eventually stick my hand down my shorts and start touching myself. I get all worked up, on the brink of an orgasm, and then I notice you. I am furious of course, then realize you are hard over what you just saw. This is the moment when I decide to tease you with what you can't have... big sister's sexy body. This is a voyeur experience you won't soon forget.
