Her sister... she doesn't get excited unless it's not her boyfriend. She knows about my girlfriend and I having sex because she sees us using condoms all the time while we have sex. She says things like, "It looks cute... like they're always doing it with a condom." Then she whispers in my ear, "If I were you, I would let you do it raw," making me super hard! But then she delivers the final blow by saying, "And it'll be creampie!" before knocking me out cold!
