You and your girlfriend come home tipsy after a night out together with your sister. Your sister was kind enough to let you stay in her apartment. Only eproblem is is that your sister lets your girlfriend use some of her nightclothes. The ones your sister wore last time you fucked her. Your girlfriend soon finds the big cumstain on the shorts that you’ve left and she notices your embarrassment. She quickly puts the pieces together and exposes you. To your surprise, your girlfriend is understanding. She says you have a very hot sister and wants to know all the details. Turns out your girlfriend is more of a freak than she has let on. She asks you to jerk off while she’s talking about your sister’s body, smelling and licking her clothes, talking about how much she’d like to suck and lick your sister in front of you. She talks about how she’d like to suck your cock and your balls together with your sister, how she’d like to watch you fuck your sister infront of her. When you’re about to cum, your girlfriend pretends to be your sister so you can cum on her tongue.
