"At some point I'd begun fantasising about being tied up." One day An learns that the teacher she admires, Chiharu, is the trainer of the Training Club, and volunteers herself as a flesh slave, begging to be trained... Rope bondage training, shame play, public masturbation, strap-on irrumatio, being turned into a bitch pet... The perverted masochist teacher, awakened to the pleasures of lesbian SM, revels in hard training play and keeps demanding harsher punishment... A secret, lewd, slave-masochist training lesbian affair unfolding in the flower garden of a noble academy.
