The father-in-law, peeking into the activities of his son-in-law's couple to explore the reasons why they were unable to conceive, discovered the son's incredibly clumsy sexual behavior! Enraged, the father-in-law used his own body to demonstrate a "sex lecture" to the couple. Kanna, easily brought to climax by the father-in-law's cunning techniques in understanding the female body, learned the tips for conception. However, Kanna's alluring physique incited the father-in-law. His guidance grew more intense, closely pressing against Kanna and forcing her into sex after intense cunnilingus. Gradually, Kanna was drawn into the father-in-law's intense, close sexual encounters, unlike those with her young husband.
