Little Sister Trap Part 2 - Only Me Forever

You've been trapped by your little sister. You thought everything was going to be nice and peaceful on your visit home from school. Your little sister had other plans though. She masqueraded as your girlfriend and convinced you to tie you up and wait for her. When it wasn't your girlfriend who walked through that door, you struggled at first. But your little sister isn't so little anymore. As she starts to rub and grind on your cock, all thoughts of your girlfriend leave your mind. The feeling of her wet panties is too much to bear. You're trapped now. Your little sister is going to jerk you off and make you cum, all while making your promise to leave that cunt of a girlfriend of yours. With your cock rock hard and her hands wrapped around it, it's hard not to say yes. You belong to your little sister now. Forever.
