Toe exercise [33 Variants + KR] (Pixiv Fanbox)

A very cruel form of punishment: The toe endurance exercise breaks most trainees within minutes. The trainees are tied up and equipped with toys, that are connected to a small box. An elastic band is tied around the trainee’s toes, which is also connected to the small box. The goal of the trainee is to scrunch their toes. Holding the toes scrunched stops the toys from vibrating, so the trainee may get some rest. After just a few minutes, a cramping sensation and exhaustion will set in from the constant struggle against the pull of the elastic bands. Trainers often use toys to tickle the trainees to further increase the difficulty. These toys can include vibrators, feathers, or very fine pens such as in this example Even more pressure can be achieved by threatening the trainees with punishment in case of an orgasm. This trainee will be left alone with an especially horny tentacle monster if she doesn’t manage to hold her orgasm for 45 minutes.
