Shigeo's girlfriend, Ayaka, is now serious, but she used to be a flashy party girl with many sex friends. In the Ayaka, Ayaka had her anus developed and was obsessed with anal sex, but Shigeo, of course, had no idea about this. Now, with the goal of living a serious life with her boyfriend, she has decided that the past is a thing of the past, but one day she sprains her ankle, but it's not quite a sprain, and she hurts a slight muscle, so she has to call for a dispatched masseuse.
