Is there a room with a curtain that says "No entry for those under 18" in an unused classroom of an old school building? The girls heard such a rumor. In the mood for exploration, they started searching to verify the truth, as if it were a school ghost story! Then they discovered a classroom with a curtain! Peeking inside with trepidation... There was a lewd world beyond imagination! And once they stepped into the classroom, they were drawn into that erotic world and ended up having sex... It seems this is a secret place where people who want to have sex gather, and it's a spot where everyone's erotic instincts are exposed as soon as they enter here! Of course, there are also teachers in this place, and it's a different space where status or anything else doesn't matter at all.
