GRMO-032 A man who works as a PC repair technician, while observing humans, was too much of a ladies' man. While teasing her innocent reactions, he accidentally seduced the perverted older sister.

A woman living alone called a PC repairman to her home. Perhaps because the man who came was unexpectedly young, the tension of the sexually frustrated woman rose sharply. She talked about things other than repairs and pushed forward, enjoying the reactions of the seemingly innocent repairman. Eventually, she gave in to temptation and fell into a lewd atmosphere… The two, originally a customer and a repairman, were now naked and devouring each other.
