[Kijima Daisyarin] Juujun Kyoushi Ch. 3 (Himitsu no Seikou Nakadashi Haramashi Toroman Kyonyuu)

A composed teacher's professional facade crumbles under her student's relentless advances, as he teases her mid-class and reminds her that their secret gives him free rein over her body whenever he wants. Her weak protests that a teacher and student must never do this sort of thing dissolve into deep kisses, sweaty sessions bent over the classroom desk, and eager worship of the cock she now craves, ending in a dripping nakadashi finish. Dazed and spent, she begs him to make love to her again, fully claiming her role as his obedient teacher.
