[Jairou] Shinjin Kyoushi Fujiwara-san no Ayashii Kyouin Nikki (COMIC MILF 2021-04 Vol. 59) [MrBubbles]

New teacher Fujiwara-san arrives at a rural elementary school where her colleagues, Fujisaki-sensei and Yamasaki-sensei, seduce her into a very hands-on "health and physical education" curriculum. The trio of teachers indulges in a wild, climactic group session, with one student eagerly volunteering to participate before school dismissal. By the final bell, a flushed and thoroughly broken Fujiwara-san signs up for "triple whiplash" training, leaving the chalkboard of her composure erased for good.
