You've wanted to rob your little sister for a long time now so you wait for the right moment and sneak through her balcony door. You find her on the bed and push her back telling her you are going to rob her. You can tell that she is secretly not trying to stop you and you have always wondered what it would feel like fucking your little sister. So you then strip her down and rub your cock on her clit. You see she is not pulling back so you tell her you you won't rob her if you get to fuck her. She surprisingly says yes, you turn her around to lick her tight ass hole. You can tell she is very into it so you don't stop until she cums. You then flip her over and slip your hard cock easily into her tight, wet pussy. Your little sister is so into it she tells you to lay back so she can ride your cock. Even though you have no condom on, she begs you to cum in her pussy. Just as you and your little sister are about to cum together, your mom walks in!! You are so close to cumming yet try to stop but your little sister tells you no and to cum in her, begging you. You can't resist, she's too hot, so you do it. You explode in your little sister and empty your big load deep in her pussy.
