At a private cram school, we go behind the scenes of female instructors providing one-on-one tutoring. Among them, the most popular is Miss Sakurai—beautiful and busty. When we directly tell her, "I want to have sex," she doesn't reject us, and other students immediately start groping her large breasts in a shocking turn of events. In the quiet classroom, moans begin to slip out involuntarily. Also appearing is Miss Endo, a serious and adorable teacher whose small breasts peek out from her shirt, catching everyone's attention. Though she seems strict at first, we gradually break through her defenses and grow increasingly intimate—reaching the brink, just one step away from kissing.
