Yuuguu Settai: Kotou no Gokuraku e Youkoso

Alright so you have it start out with a swimming team coming to a local resort for training in the up coming important tournament for school. Once they get there the new caretaker it shows found a collection/rape diary of the previous one that is now handicap and living beside the resort.

It shows a scene of the new caretaker and how he became handicap after saving him the owner of the resort offered him the job and he took it. The prev owner would film the swim teams that came and tape them using the blackmail against them to rape them.

An incident has come up ... with the new caretaker already having indecent thoughts he gets in a type of misunderstand where one of the girls makes fun of him making him mad. This is when he choices to get revenge from the girl. He takes the equipment he found and uses it to tape the first girl in her most intimate moment using it as black mail calling her to the office. There he rapes her and takes her virginity.

He starts getting carried away so decided to get the other girls there. He then tapes the other masturbating over how she loves her brother etc and black mails her. Once he rapes her he gets the 2 girls to work against the other 2 in secret and get them to black mail.

Once he does all the blackmails and gets the girl to do as he wishes he rapes all of them all night at the same time while they do indecent things to each other letting him watch. This being said once its time to get picked up from the training the boat guy comes back finding them all in the room passed out naked with embarrassed/ horrified look on their face. But the guy is there smiling. ( go figure )

At the end of it the guy gets caught drifting in the ocean and arrested for rape/assult etc. And the swim team losses but rumors of the rape are getting out. Since they captain of the team wont talk after the loss they dont have anything to confirm it.

The end it shows the guy that gave the job to him he knows about the man getting arrested for it. At first he looks mad, but then he smiles and calls him foolish. Then it just randomly ends so you dont know what happens after that with the guy or the man that was smiling.

Overall it basically a rape story and you kinda feel sorry for the girls in the story and how it happens.
