[Maruarai (Arai Kazuki)] Demi-chan no Seikyouiku (Demi-chan wa Kataritai) [YxTL]

Sakie Satou, the bespectacled teacher with a soft, voluptuous figure, decides to show her colleague Tetsuo just how sincere she can be—stripping down and taking him for a breathless ride while her fanged student Hikari watches in wide-eyed amazement. What begins as a comedic shock quickly turns into a sweaty, passionate lesson as Satou-sensei grinds on top with growing abandon, insisting it's all for her own sake even as she moans and loses herself in him. Between the teasing banter, the gasping climaxes, and her thoroughly spent, blushing afterglow, this after-school encounter proves the shy teacher is full of surprises.
