ONNA KYOSHI YUKIKO
Hentai game about a teacher who is tricked into having sex with men at her school. The game has a story in Japanese text in the usual visual novel/eroge format but also an interactive adventure part. During the first part of the game you explore the school by selecting rooms from a plan to discover useful items to use on the teacher. In the second part you select items to use on the teacher and you get different adult scenes depending on which you use. The teachers part is voiced at some points also the games graphics are not that great although it does have a few animations. There is a limited gallery mode but it is more useful for making sure you find everything since it doesn't store all the CG and animations. Make sure to save once you have found all the items in the school before clicking the proceed button (yellow arrow at the bottom) on the plans. Have fun!
