The director sends the AV industry's No. 1 pick-up artist to the homeroom teacher at his alma mater. The director then gets her to seriously try to woo him, and secretly films her until she opens her legs for him in this forbidden AV project. Her lewd face, which she never shows to her students, her highly sensitive nipples, and her sex that is too raw... The teacher herself is still working as a teacher, unaware that she made her AV debut.
