MBMH-018 - Confession: The 50-year-old mother's dark history, a 4-hour record of being broken and trained by her own son.

I bought this because of the '50-something mother and son' premise. It's about a son training his mother. There are 6 works featuring Chisato Shoda, Michiko Uchihara, Yukie Shoji, Hidemi Sugimoto, Nanako Sakurai, and Kanae Nakayama. I wondered why Nanako Sakurai was included, but since I like her, I kept watching—she actually has the longest runtime. Well, she likes being bullied, so I guess it's fine. I really like Michiko Uchihara's expressions when she's being teased.
