Omg babe! Were you jerking off? It's okay, it's okay. You don't need to be embarrassed. What were you looking at? C'mon lemme...oh. Oh wow. You were looking at a picture of your sister's tits. No it's okay. Sorry I don't mean to laugh. That's kind of fucked up, but kind of hot. What I pretended to be your sister while you jerk off? Here I'll take my tits out. Just stroke for your sister's fat tits...
