A widower researcher and a fellowship of flesh woven by three women! Researcher Keisuke Taniguchi has finally come up with the result of 30 years of research that ``sexual desire has the greatest impact on the human body''. In order to confirm this, he made appointments with three women of different ages, but the women who appeared in front of him turned out to be lewd and perverted beings that far exceeded his expectations! Excited to see different types of attractive women leaning back in the narrow screen and pleasure! It's a book that makes the blood flow in the crotch!
