When my father-in-law opened the door to take a bath, my wife was taking a shower. The father-in-law, who happened to see the body of his daughter-in-law, said, "How beautiful. I envy my son...". The daughter-in-law who was happy with the words washes the body of her father-in-law and gives a fellatio. The two of them get closer because of this event. After the husband fell asleep soundly at night, the bride visited her father-in-law's room in the hope of being held, and the two crossed the forbidden line.
