I got a step-sister. She is a cheerful and lively girl. She always wears bloomers, which were given to her by my mother, as an inner layer under her skirt. She says, "I'm not embarrassed because I'm wearing bloomers!" Living with such a sister meant that I, a bloomer fetishist, had to get an erection every day. This volume contains two thrilling situations involving my step-sister who wears bloomers.
