This 2009 video from TMA is a parody of a popular series of guidebooks called Health and physical education for 30 year olds, which has been adapted into manga and anime.
This video actually serves as a sex education resource for men, giving useful tips on how to have safe, consensual sex. It stars my favourite female JAV performer, Mizuna Rei, and my favourite male JAV performer, Narusawa Kenichi (a.k.a. Goro). Mika Nurie serves as the narrator.
In each chapter, we see Goro start off being ignorant or selfish about sex in some way, to demonstrate what not to do. These scenes can be incredibly amusing. These are then followed by an example of what to do.
The sex scenes are not meant to be particularly erotic, but rather designed to demonstrate how to have pleasurable sex. And actually, Rei and Goro have a real chemistry together, and it makes me feel like I'm watching a real couple.
At the end, we have an enlightening 25 minute interview with Goro, in which he discusses a wide range of topics, from cosplay to his background in the games industry. It's rare that a JAV includes an interview, especially with a male actor, and it's something I would like to see more of.
The only criticism I have of this video is that it was released during the transition from 4:3 aspect ratio to 16:9. As such, the video is presented in letterboxed format, with black bars on the top and bottom (which I have cropped out of my screenshots). Otherwise, though, this is a very unique video that manages to entertain as well as educate.
Rating: 9/10
