You play “Professor” Hitosuji, well-known reputed tutor and teacher for his
abilities in turning even the worst students into straight A stars…although
it might be just a coincidence that all those girls happen to be very young
and beautiful students. His “private tutoring skills” might be somewhat
questionable, but it works.

In Immoral Study 2, the task at hand is to tutor one Yuko Ijima, the only
daughter of a big time factory CEO. She’s been slipping in her grades lately
and her father called you to put her back on the right track again. Oh, she
has a major attitude problem. Nothing you can’t handle though.

Another linear hentai game where all you have to do is click on the mouse from
beginning to end, which surprisingly is a very short game by the way (less
than an hour). It does come with voice support and pretty nice animated
graphics, although it is partially censored.
