Caught watching my stepsister with Kasey Warner

You have been caught watching your stepsister Kasey in the bathtub. She threatens to tell on you unless you jerk off right there for her. You don't have a choice, so you take your dick out and stroke off. As you stroke your dick, you notice that your stepsister has nice, small tits and a very hairy pussy. Kasey stands up. She is wet and slippery and your dick would slide into her very easily, you think. She turns around so that you can see her ass. You become more aroused when she calls you a pervert and you stroke yourself very hard until you explode right there in the bathroom. Kasey gets up and leaves you there with her dirty bathwater.
