Kanna is easily climaxed by the old-fashioned technique of her father-in-law who knows the female body. It was a couple who learned the tricks of child making, but Kanna's disgusting body makes her father-in-law feel like it. The father-in-law's instruction becomes more radical, and he comes close to Kanna and visits intense cunnilingus and forcibly brings it into sex. Kanna was gradually taken in by her father-in-law's thick close contact sex, which is different from her young husband.
