Geki!! Monzetsu Operation Plus (John K. Pe-Ta)

In this grotesque erotic manga parody by John K. Peita, a reprint of his 2005 book 'Intense!! Agonizing Operation Plus,' a fraudulent fortune teller and an anthropomorphic slug-man subject a horrified virgin schoolgirl to extreme sexual violence and invasive slithering through her body. The story parodies Ghibli's 'The Cat Returns' with crude humor and fourth-wall breaks, featuring tags such as ahegao, deepthroat, tentacles, and incest. The volume's afterword includes the author's self-deprecating monologues and standard publisher information mixed with absurd, meta humor.
