You get an unexpected video call from your sister. You answer, and there she is! Naked, fingering her pussy. There's no way she meant to call you, but you can't help watching She looks up, and notices it's you she called! She meant to call her boyfriend... but when you begin touching yourself over her, she says that oddly, she feels flattered. She's still horny, and so are you, so why not get off with your sister on a dirty video call?
