[Synopsis]

In an era when the birthrate was declining and children were no longer being born... what saved us was the [Forced Sex Enforcement System], which was implemented by the whole country.
The problem of the declining birthrate was then solved and several systems were created to prevent the same mistakes from being repeated...
One of these, the [Sex Education System], is a system that provides full-scale sex education while people's sexual knowledge is still immature and even lovers are forced to have sex with other people...
The victims of this are the lovers Kotaro and Asuna in this work.
Asuna is heading to a depopulated village for her training.
Then, while Kotaro is waiting for Asuna to return, he receives several video letters, which show his girlfriend Asuna doing her training...
However, the image of Asuna shown in the video is not the Asuna he knew before but his precious girlfriend moaning like a beast and being gang-raped by the villagers...
----------------------------------------------------
Such is the story of Asuna the whore (͠≖ ͜ʖ͠≖)
