Part one of three. Rachel Steele and her step-sister Julia are out on their back porch watching Julia's stepson do some much-needed yard work. They are wearing bikinis because it is such a hot day and he is wearing only his swim trunks. They light up a couple of cigarettes and their conversation is mainly about Julia's stepson, his hot body and what they imagine he has got in those shorts. He comes in from doing the work and says he will get some water. They giggle and laugh with each other and with a little prodding from Rachel they both go into the house to get some water, too. In the house, Julia goes to her bedroom and sees that her stepson has all her underwear on the bed. He is literally rolling in her panties and jacking off. She pretends to be shocked but really she is turned on.
