Your cock is throbbing as you rub her feet in your lap. You can’t help but find your step-sister cute when she’s all bratty and sick and mopey. She grazes your dick with her foot... accidentally at first. But then intentionally... You pull your dick out of your shorts a little... just to feel her toes on your bare cock. She starts touching herself... Neither of you say a thing... It all happens so fast. You start stroking as she rubs her pussy... then she pulls her shorts down and you know that she wants it... you slide your cock inside your step-sister...what the fuck are you doing?
