[Diamond no Kidoriya (Mario, Hazama Levi)] The Birth of a Spoiled Masochist (Blue Archive) (Incomplete)

A frail, blushing Sensei strapped to a chair learns he has been "punished" for an unspecified transgression and is about to be molded into a spoiled masochist at the hands of two merciless students. Asuna, in a revealing maid outfit, lectures him on the severity of his sentence before Rio and another bunny-suited companion pin him down in an intricate, drawn-out scheme to wring him dry without letting him climax. With nipplestim belts, chastity, and prostate teasing, the giggling pair trade off stroking and slapping while Sensei squirms, begging for mercy he knows he won't receive.
