Up and down (Pixiv Fanbox)

Trainees are expected to be quite fit. The dungeon does enhance their physical abilities, however, exercise is still key. Trainees are also expected to climax on their trainer’s command. Luckily for us, practising physical strength as well as control over their orgasms fit together perfectly~ Here we see a trainee in the middle of a workout session. She has to raise and lower her hips repeatedly to strengthen her muscles. Her trainer conveniently placed a large toy below her, forcing her to penetrate herself with each rep. She’ll only be allowed to cum if she manages to finish her routine. If not, she’ll be denied and forced to wait until her next chance to redeem herself~
