The first volume of an omnibus infidelity diary of a lewd married woman set in a certain educational facility.

Lisa Kuriyama, a user of an educational facility, has a perverted fetish that she cannot tell anyone about.
One day, she is seen and filmed by Nashio Kokita, a man who works as a janitor.
Kokita called Lisa to the janitor's prefab and showed her the video and threatened her.
"If you don't want the video to be taken to the police, have sex with your husband and come to the janitor's office at night."

Lisa Kuriyama was a former career woman and elite.
Her pride was high and she looked down on all her men, including her own husband.
Nashio Kokita, a janitor, was a man from the bottom of the world with his ugly appearance.
Lisa is threatened by such a man, and she is given humiliating commands one after another.

Her Lisa's pride is being destroyed more and more by Kokita.
In the end, she crosses the line of her own volition...

And the pleasure given to her by her affair with Kokita erodes her Lisa,
Her unbearable lust drives Lisa to become even more unfaithful...

A new man also appears in front of Lisa...!?bkyu(Twitter:@Bkyusite)[Number of pages] 70 pages
