Synopsis:
The year is 20XX.
The "M generation" is a time when men in their 20s have become increasingly masochistic.
The increase in masochistic men has led to a further decline in the birthrate...
In order to stop this "male masochism", the government established "group homes" to cure masochists.
However, in reality, they have become a den of "bad female staff" who prey on masochists for government subsidies and admission fees!
Under the guise of "rehabilitation", the staff further turn the men into masochists...

Please note that ASMR audio has a different scenario than the manga above, it is to make you the protagonist and immersed in that world:

Nakagawa Kasuga, a group home staff member who also appears in the manga, will guide the protagonist (you) who entered today around the facility.
First, there will be an explanation of how to enter.
Then, the chastity belt will be fitted and checked.
Then, it's time for some naughty rehabilitation...
And then, as a reward, it's time to "ejaculate once a day"...
Can you withstand this melting pleasure?
