Curious about what makes women climax? Struggling with stamina? Don't worry, Professor Yui Hatano is here to teach you everything you need to know. A masterclass that covers all your adult questions with practical, hands-on demonstrations. Don't miss this lesson!




















*The scene where he gets a hand job while on his knees and ejaculates was the most exciting. You can tell how good it feels when he ejaculates by hearing the man's cries when he cums. Mr. Hatano's hand job also seems to feel really good. The first time I saw this video. I was so excited just by the kneeling handjob ejaculation scene that I pulled out 7 times in a row. The way the sperm flies, the way it splatters, the way the man makes a sound and seems to enjoy it, it's super erotic. It will come off like crazy.
Yui-san explains the mechanics of the male and female body so thoroughly that it's even better if you watch it with your partner. At first, Yui-san gently guides another actress, but afterwards, she demonstrates it herself, allowing you to fully enjoy her beautiful body. Plus, the mosaic is quite thin, so you can see all the details. It's definitely worth the purchase; I'm actually glad I bought it.
I bought this to prepare for my first sexual experience. It explained things in such detail that I was able to get through it successfully! It's probably better to view this as an educational tool rather than just an AV.
Yui has a lot of releases, so naturally, it's a mixed bag, but this one is definitely a 'dud.' The image quality is also pretty poor for 6000kbps. If I had rented this, I would've felt like I wasted my money.
