Clad in a t-shirt, clumsy grannie's panties and dirty white socks, my chubby buxom phat-assed step-sis came into my room and asked me to help her program the washing machine, so that she could wash her clothes. I agreed, but her awkward apparel made me so horny that my boner pressed against her booty. She realized what it was all about and, forgetting about the laundry, hurried to please me with a nice blowjob and hot dick riding. I appreciated it and rewarded her with a creampie. @Stammel
