PART TWO: Slutty Step-Sister's Helping Hand - Fucking my step-sister has made things so much worse. I can't even be in the room with her now. So I decide to tell her I need help, I need her to take care of my raging hard cock. She says no at first, but I push and push and finally whip it out, and that does it, she starts off like she is doing me a favor, but she starts getting horny, and it goes better than I could hope with her moaning and cumming all over my cock. I think that first tired fuck got something going in the back of her mind.
