Stepsister pegs you for perving

Your hormones have been going crazy recently. Everything turns you on, even your step-sister. You have tried outlasting, yet have found yourself perving on and masturbating for her on more than one occasion. And, now, she knows about it. She claims that she can forgive you if you just admit it, but you refuse. There is no way you can openly admit that you get off from perving on your step-sister. At this, your step-sister gives a wicked little giggle and leaves the room. When she returns she is grinning from ear to ear and stroking the big strap-on cock she is wearing. Since you love getting off from your step-sister, she has decided to be an active participant in the act. She is going to peg you and fuck your ass until you cum. You can make it stop at any time by just admitting to perving on her. But, she knows you won’t. You are such a horny pervert that you will happily take whatever she wants to give you.
