【890 Squadron】Happy Hairball Keseran Paseran

She has developed a counterattack technique where she sacrifices her own panties, and is no longer defeated by bad tentacle monsters.

One day, however, she finally runs out of underwear and goes to a shrine warehouse to look for some second-hand ones, only to find a keselan paselan (tentacle) that forces her to be happy.

This is an R18 tentacle book with 30 pages of tentacles on the back and front covers.
