Seven years after the completetion of Yoiko, Noguchi-sensei found a surprising opportunity to star in an adult film which she decided to take on. Yoshino Miki, the voice actor of Noguchi-sensei starred as a supporting character in the Hentai OVA, Haitoku Tsuma. She plays Eriko, a voluptuous and big-breasted bitch. If you have not seen it yet, I recommend it. I found it rather strange though at the same time pleasant hearing the same kinds of squeals and sounds that she made in Yoiko. The OVA is two-episodes. She plays Eriko in the latter. And yes, you’ll need tissues!
P.S. I’ve updated the status on Machiko Sensei, so check out the status page.
