MAMA-356 - Mature Cabaret Virgin Graduation

First, a sex lecture demonstration by Manager Yuki and Mr. Jo Oshima. They explain things while demonstrating, but when it comes time for penetration, the teacher suddenly goes limp. 'Even with over 20 years of experience, this happens sometimes,' he says. It seems like he's actually teaching properly, but the impression is that he explains, goes limp, explains, and goes limp again. Manager Yuki is putting in the effort, too. But all that effort is cut out. I felt a strange sense of kinship with the teacher when he got laughed at for explaining a full nelson move. Aside from that, there are two assistant managers (Kano) and the others, including Yuki, each have their first time. There's a scene where four people gang up on one (I wasn't interested, so I skipped it, details unknown). There are no hidden male actors; they all seem to be genuine amateurs. Since there are 7 encounters including the teacher, it's heavily edited, which is expected for amateurs who finish as soon as they penetrate. Also, the image quality is poor.
