Suddenly, I got a cute and stylish stepsister, and our unfamiliar cohabitation began! But my stepsister's loungewear is too extreme for me, the stimulation is too strong, and I get an erection whenever we're together! I try to hide it, but when my concerned sister lightly touches my dick, I immediately come. My super sensitive premature ejaculation makes me feel pathetic, like I've wet myself. Just as I'm thinking this, my sister suddenly pulls off my pants, takes my dick in her mouth and says, "Sister will cure your premature ejaculation"...!
