A BEST selection that includes 6 titles of the early works of the real sex education series has appeared. The actresses are Nanako Mori, Mai Kuroki, Nao Mizuki, Rio Hamasaki, and Maki Hojo. What the six people have in common is a beautiful body and kindness. A mother who responds with her body to her son who seeks sexual knowledge involuntarily feels her son's Mara. In particular, Nanako Mori, the first work, is a big hit and not only the best selection, but also a single work that I would like you to take your time to see! Of course, the other five titles are also masterpieces.
