I'm surprised there's such a box that's big enough to fit the two of them, doesn't suffocate them despite all their heavy breathing, is soundproof, AND doesn't fall apart from them having sex in it.

Hentai sure is full of awesome boxes.

Read every "auu" --> imagine that sound she makes --> imagine entire scene full of those sounds --> laugh so hard that boner is lost --> repeat.

I'm curious who the two in the club room was. Hope there's another one where it's the mystery couple. Please let it be Kumin.

Good stuff, and I just so happen to know where to find boxes like that but I have never gotten an invitation to that universe.

@Demosthenes: I guess these boxes are surplus from the Metal Gear universe.

Boxes are the official napping competition arenas.
