Humiliating feet (Pixiv Fanbox)

How humiliating it must be for a proud trainee to first be edged until they can’t control their bodies anymore from all the denied pleasures, only to be left at the mercy of their trainer’s feet. Rubbing themselves against their toes and soles, desperately trying to stimulate their weakest parts while their trainers hold them by their ankles to control the pressure they’re allowed to receive is a truly cruel fate~ Will she finally be allowed to climax from her trainer’s feet, or is her trainer going to merely tease her more?
