[Sakimori Dan] Munemori Matoi Can't Get Away (COMIC Mugen Tensei 2019-10)

Munemori Matoi is a truant schoolgirl with a tiny, midget-sized frame and impossibly big breasts, and her tall young teacher can't get through a single study session without ending up buried in them. What begins as a lecture about skipped classes and looming exams melts into sweat-slick breast-grabbing between the library shelves, her tearful cries of "Sensei!" pulling him under even as he swears this is the last time. And when the afterglow means nothing to her — she's already begging him to fill her up, then waving a brand-new bondage game in his flushed face — keeping this insatiable girl occupied becomes a full-time job her exasperated teacher never signed up for.
