My father-in-law, Tetsuro, who lives with me, has recently become so blurred that he often bothers his son's wife, Kotone. However, Tetsuro takes it in the wrong direction and pretends to be wrong with his late wife, Setsuko, and attacks Kotone who was taking a bath. Tetsuro who tasted it licked Kotone's pussy with the same technique aiming at the time when there was no son, and finally invaded the flesh of desire into the vagina. Without telling her husband a nasty act with Tetsuro, she is blamed by her father-in-law and her father-in-law and repeats convulsions.
