[Arimura Daikon] Bewitched by a Black Flower (COMIC Anthurium 2022-04) [Redlantern]

A brash gyaru turns a mundane dress-code scolding into an opening, dropping her eraser under her teacher's desk and daring him to stay quiet while she works him with her mouth—because if anyone finds out, both their lives are ruined. From there she tightens her grip, riding him until he forgets everything else and whispering that she'll take another woman's place in his life entirely. By the time he's canceling plans with his own family to stay the night, breathlessly pulled into one more round and a hungry kiss, it's clear the black flower has him completely bewitched.
