My stepsister is tired of me not helping her around the house

I rarely help my stepsister clean the house. I’m usually too lazy but I always feel a twinge of guilt about it. This time, she caught me and told me exactly what she thought of me; she was furious and upset. I finally offered to help, and she was thrilled, but then my hormones took over. My cock got hard at the sight of my stepsister’s juicy ass I’d had my eye on her for a while, after all. But now, with her right here in the laundry room next to me, I want her. I’ve dreamed of this for so long.
