Based on the adult game by Elf. Maro, a pervert, works as a doctor. One day, Sakimi came to his office asking about a small pain and soon he begins to gain her trust and give her advice about marriage life, specially about making babies. Of course he takes advantage of her trust and begin to sexually caress her in several parts of her body. One day the doctor did this in the front of Sakimi's husband, resulting in the husband smashing the doctor's hands. Since Maro cannot use his hands anymore for some time, Sakimi secretly helps the doctor since she feels responsible (she never doubted of the doctor, as she always thinks the doctor is just doing his job caressing her). Maro now cannot eat, bathe and even urinate alone without the help of Sakimi, and she with good will, tries to help him out in everything. What will happen next?
