When he went to an M-girl image club to vent his frustration at being scolded at work, he encountered Natsume, who worked as a M-girl! Although he was surprised, he took advantage of Natsume's weakness and moved into his house, where he began living as her master. Natsume also unleashed his natural M nature and was pistoned by Tamura's dick every day.
