Forensic investigator Josephine Jackson is alone in a crime scene, collecting samples in a dimly lit mysterious hotel room. The room is silent until a strange wet sound breaks the stillness. Josephine turns toward the bed and sees a woman, Emiri Momota and covered in sticky slimes. Startled, Josephine approaches cautiously, speaking in a shaky voice. She informs Emiri that she’s been missing for days, but Emiri, panicking, warns her that “it” doesn’t let anyone leave. Josephine seems to ignore her words and as she moves closer, Emiri yells for her to stay back, but it’s too late. The bed starts to rumble, transforming into a monstrous mouth that devours both of them. Inside the creature, Josephine awakens, completely naked and covered in monster’s sticky saliva. Emiri, lying besides her, apologizes for not warning her sooner. Terrified, Josephine tries to escape, but Emiri reveals there is no way out of the monster’s belly. Soon, Josephine realises that they’ve been trapped inside the monster. Suddenly, a slimy tentacle slithers up their sexy legs, penetrating Emiri instantly. She moans uncontrollably as the evil tentacle invades her body, and before Josephine can react, the tentacle enters her too. Both women are helpless as the creature toys with them, pushing them into an overwhelming and bizarre climax. Exhausted and defeated by the wrath of the monster tentacles, Josephine tries to crawl away, but Emiri, tells her to give in and stop trying to escape as that’s not an option. The tentacles return, and makes them orgasm once more, Josephine realizes there’s no escape. She collapses, trembles, and crawls back to Emiri. The two beautiful babes, defeated and drenched in slime, cling to each other in the monster’s stomach, finding solace and weird pleasure in their shared captivity as they slowly drift into exhaustion and nothingness.
