His mother had just died, leaving only his lonely godfather in the countryside, so the son decided to pick him up to live with his wife. However, since the day he came up, it was also the days that made the couple's life no longer as happy as before and often encountered turbidity and troubles, especially his wife Isshiki. Ever since he stumbled upon his daughter-in-law's nudity in the bathroom, it seemed that his strong and energetic natures had suddenly awakened. Just like in spring, he also had longings and cravings at this age, which is why he could not control himself and raped his daughter-in-law despite her resistance. Not stopping there, also in this bathroom, there were many incest between the father-in-law and the bride afterwards. Every time she went to take a shower, he would snoop in advance and wait for a good opportunity to act. As for the daughter-in-law, although she knows he is a despicable old goat, she does not tell her husband about this and remains silent and endures, perhaps partly out of fear of disturbing the family situation, but mostly because she is too licentious.
