My girlfriend's younger sister is sooo hot. I've wanted to fuck her forever... I came here to meet my girlfriend but she's not home. Her parents aren't home but guess who is home though? I hear moans coming from her little sister's room so I'm gonna check it out... To my surprise I found her masturbating and all alone. I start to jerk off but she caught me! My desires of her got the best of me and now it's time to make my move. My girlfriend will be here any minute. Her sisters warm tight pussy makes it all worth it and I don't even care if we get caught though.
