The hero Serizawa Seiro did not have good grades in school, and is ranked low. The time for the school trip was approaching, and he was one of the few who did not feel well, but was included by the director in the group that went to the museum.

But shortly after being sent, he becomes dizzy ... which leads to his transition to another world.
Seemingly indistinguishable from the real in a glance, it was a parallel dimension in which gender traditions and chastity are upside down!

Involved in this new life, he is suddenly caught and treated by a beautiful girl.
Puzzled at first, he ultimately decides to take advantage of the situation.

"Director, I want to have sex"
"Really? Good!"
Fulfill the request and lose your virginity!
However, the evil girls who noticed this scene blackmailed him.
"If you don't want someone to know about it, have sex with us."
Hilarious reverse rape?
Love motel, sex with two teachers on their return to the hotel, and then with the hostess and her daughter, this is a school trip full of eroticism!
