Female Teacher's Agonizing Hell

About
This is a small adventure game starring a group of cold-blooded delinquents. It is part of Alice's Cottage 3. It takes place over the course of 9 schooldays.

It is a standard ADV game where most of your meaningful choices are made during sex, except for one choice which can end your game. It has a happy ending switch in case you find the game too dark.

Story
In this school there is a trio of terrible delinquents. Ryuichi is always looking to fight or have sex, Kenzou is happy as long as he is drugged up and Yumeji the otaku lolicon. They are an unlikely trio who have been friends since they were kids.

Ryuichi, the leader, is bored as usual. He is planning on skipping class as the homeroom teacher is late. Just when he decides to do so, he pops in with the new student teacher, Asuka Kyouko.

Ryuichi is immediately interested in having his way with her and sets up plans to do so with Kenzou and Yumeji. What horrible things do they have in store for her?

Endings
There are 4 endings to the game, but they are easy enough to get:
 * Happy ending mode intrusion at the end of a day.
 * Intrusion on day 8.
 * Finish day 9 in happy ending mode.
 * Finish day 9 in normal mode.
