Yui HATANO, a tutor of Shizukutacon who is envyed by his teacher Chi-po

The older sister of the tutor has been an excellent tutor who has grown the grades of several students so far. However, he actually likes shibatakon and komamo. While concealing such sexual jealousy, I proceeded with the class, but I was overwhelmed by a pussy of "Hajime-kun" and the insects of Shikotakone crawled. And finally, the reason is pure! My sister, whose self-control has collapsed, turns into an erotic woman.
