[Otakumin] Bizarre!! Brainwashing!! Black Gal Beam!! ([Nukoya (Various)] Kuro x Shiro Gal Goudoushi 2) {EL JEFE Hentai Truck}

Koito Ayumi, a busty 26-year-old PE teacher counting down the days to her spring wedding, has her life derailed when a mysterious 'Black Gal Beam' strikes her, transforming the prim educator into a dark-skinned, foul-mouthed gyaru whose body obeys anything but her own will. Helpless against the smug otaku who wields the power, she's bent over and claimed while thoughts of her devoted fiancé still flicker through her breaking mind, begging to be filled even as she curses him — until the headmaster arrives to intervene, only to share the same fate, both curvy, hairy teachers reduced to trembling, soiling messes side by side. A gleefully cruel mind-control romp where every shred of a teacher's dignity gets stripped away one beam blast at a time.
