Unable to resist the temptation of his fiancee's unintentional breast exposure, the father-in-law's reason abandoned him... Hinano, his son's fiancee who is scheduled to marry next year, is a lovely and well-mannered woman with a beautiful face and large breasts. When they visited the house where the couple was living together for a pre-wedding celebration, he was unable to control his erection after seeing her cleavage and the scent of a young woman. Having been widowed for a long time and without any female companionship, the father-in-law took advantage of his son's absence and assaulted her... "Please stop without a condom," Hinano pleaded, but he relentlessly fucked her until the condom box she offered as a last resort was empty.
