The teacher is unconsciously provoked by the close-up of the big-breasted knitted girl in a space where they are alone, and finally loses his senses! He squeezes her soft, huge H-cup breasts! Even though he knows she is his student, he can't resist her breasts! Gradually, the student begins to desire the teacher's dick... He gives her a titty fuck and bounces her plump body in a sensual cowgirl position, and he enjoys cum shots and creampies until his balls are empty!
