Unemployed and single, Sho hires a rental girlfriend to impress his friends—only for his former classmate Azu Amatsuki to arrive. She has recently become a popular porn actress, but secretly joined the service because scripted shoots keep her from losing herself in real sex. Their awkward reunion soon heats up: she gives him a discreet blowjob in a family restaurant, tries a women's erotic massage with his therapist acquaintance, gets swept into a three-way and cums hard, then returns to Sho's home for slow, passionate sex. With her huge breasts bouncing through orgasm after orgasm, Azu finally releases all the pent-up desire she cannot satisfy at work. Will this mutually beneficial arrangement become a real romance?
