[Momofuki Rio] Ore-sama no Asobi (COMIC AUN 2022-02) [desudesu]

A bratty dark-skinned gyaru with massive breasts catches her disciplinary teacher red-handed stealing panties and bleeds him dry with blackmail, until he turns the tables with a phone app that renders her uniform invisible in public and quietly rewrites her attitude. Revenge curdles into something hungrier as she drags him to a hotel by the collar of his dignity, riding him like a succubus in fishnets and demanding his cock in every hole she has. When the app's final unlock hits, the power balance flips completely—she's collared, calling him Master, stuffed all morning on his orders, and utterly unable to live without him.
