The 44th commercial release from the indie AV circle All-Japan Turtle Tribe Cooperative / Delusion Tribe stars R-chan, an angelic schoolgirl cosplayer with a childish face and a petite 140cm frame. A popular figure at cosplay events who constantly captivates shutterbug otaku, deep down she despises her fans, thinking they're "gross" and "insensitive," with an attitude that's arrogantly condescending. This production aims to correct her personality through intense training, transforming her into a true idol—an "indecent cosplayer" who exists solely to serve fans by using her pussy to the fullest. The plan involves total domination via gangbangs by otaku groups, impregnation, and even marriage to members. Lured to the studio under the false pretense of shooting a cosplay ROM, R-chan is subjected to brutal gangbang training. Screaming "You stink!" and "Stay away from me!", she's forced to endure otaku saliva, anal and genital assaults, yet despite her defiant front, she becomes wet with masochistic arousal, eventually begging, "C-Can I cum?!" Under relentless vibrator attacks, she shrieks, "N-No, I'm already cumming—ah!", erupting in powerful squirts. Continuously tormented, she falls into endless orgasms until a real cock is thrust inside her. What follows is an extreme series of on-camera creampie fuckings. Though she initially screams, "I don't want to have a nerd's baby!", she soon descends into madness, crying out, "Fuck me harder!" and "Come inside me, Uncle!", collapsing into a complete personality breakdown as a living cumdump. Captured on film alone are 19 creampie loads, showcasing her ultimate reactions—screaming, tongue-lolling, eyes rolled back in convulsions—as this idol girl is conquered and utterly feminized by the very otaku she once loathed.
