You go into your sister's room and see she's dressy super slutty. even though you know she's grounded. You keep asking her ad she finally says she's going to sneak out to see her bf, so you tell her you won't tell if she rubs your cock with her tits out. She is so annoyed with you but doesn't want to get in trouble. She does it, but she's annoyed defiantly. then you keep pushing it, knowing she won't say no because she wants to go see her bf and not get in trouble! It all leads to fucking her and cumming all over her pussy! You're such a little perv!
