Married for five years. Married life is going well, but Fumika is looking for excitement in her boring days, so she starts working part-time at a convenience store three days a week. Unlike her unsperm-bearing husband, she is attracted to the younger college student who works there and treats her kindly as a woman. In the store, in the back room, in the office, at the man's house... They have intense creampie sex over and over again. Fumika's voluptuous body is just too erotic... The man and woman have sex 20 times.
