Were sitting next to each other on the couch, home alone. I notice you moving around a lot for some reason underneath the blanket…. its weird but I keep looking at my phone.. until I get bored of it and want to look at yours! I catch you looking at a girl in a bikini.. not just any girl.. its me!!! I pull the blanket off and realize youre jerking off!! right next to me!! while looking at me!!! You little freak… little do you know I’m a freak too and.I like it. So I do what any sister would do.. I help you out!!!
