HUNTC-474 | Once you step through the noren curtain that says "No entry for those under 18," you can have sex with sexually frustrated female students whenever you want! Behind the noren curtain that says "No entry for those under 18," there is eroticism! The 18 only space created in an unused old school building has become a hot spot for bored students!

In an unused classroom in the old school building, there is a room with a curtain hanging that prohibits entry to anyone under 18? A group of girls hear such a rumor. Like a school ghost story, they set off on an adventure to find out the truth! They discover a classroom with a curtain hanging! They timidly peek inside... and find an unimaginably lewd world inside! And once they step inside the classroom, they are drawn into this naughty world and forced to have sex... It seems that this is a secret place where people who want to have sex gather, and the moment they enter, everyone's erotic instincts are exposed and they have sex like crazy! Naturally, there are teachers there too, so it is a different world where status doesn't matter at all.
