After earning some money from his part-time job, Kazuya decided to treat himself to a visit at his favorite mature-women soapland. But as soon as he arrived at the shop, the girl he had requested seemed to be taking a long time preparing and didn't come out right away. Growing slightly impatient, Kazuya decided to wait. When she finally appeared, he was met with an unbelievable sight—standing before him was his own mother, who had been at home just moments ago. Trembling in shock, Kazuya turned to leave, but she stopped him, saying, "I'm the number one girl here. Since you came all this way, why don't you stay and enjoy yourself?" Caught in this bizarre situation, Kazuya's mind began to waver.
