In an unused old school building, there's a room with a sign saying 'No entry for those under 18'? Girls heard this rumor. Feeling like they were in a school ghost story, they decided to investigate and started exploring! Then they found the classroom with the sign... Peeking inside cautiously... There is a world of lewdness beyond imagination! And as soon as you step into the classroom, you too are drawn into this perverted world and forced to have sex… It seems that this is a secret place where people who want to have sex gather, and once you enter, everyone's erotic instincts are laid bare, turning it into a spot for non-stop fucking! Of course, there are teachers here too, and positions don't matter at all in this alternate dimension.
