You’re chilling on the couch next to your petite stepsister, her bare feet resting close to your lap. You say her feet are bothering you. She smirks, wiggles her toes, and teases that you always stare at them because of your obvious foot fetish. Without warning, she slides her soft soles onto your crotch and starts rubbing slowly. Your cock gets rock hard instantly under her feet. She keeps stroking through your shorts, giggling at how quick you got stiff. Things suddenly escalate quickly.
