You will cum for your step sister, pervert! (w/Harley Jade)

You love a fit girl and your step sister Harley is definitely fit. You see her doing yoga and you cannot help but silently watching. Something about her legwarmers appeals to you. Also, her ass is supreme. You cannot help but perving out on her, but she catches you and threatens to rat you out to your parents. She knows you were just going to go back to your room and jerk off thinking of her later, so she decides that you should just do it right here and now. You have no choice, so you get your dick out and leave your fate in her hands. The fact that you are already hard when you take your dick out grosses her out, but she demands that you jerk off for her. In her generosity, Harley takes her tank top off and lets you see her perky tits. Oh, you want to see her ass, too? Fine. She takes off her yoga shorts and now you can see all the she has. She wiggles her ass and you marvel at its jiggliness. Harley is eager to see you cum and she informs you that you will cum into your own hand.
