Training the senses (Pixiv Fanbox)

As a trainee you’re expected to be in charge of your body, that means being able to fully control yourself and your bodily functions. To practice this, we usually tie trainees up, so their arms and legs are completely immobilized. Then we insert a vibrator and set it to a relatively low setting, enough to cause some serious pleasure but too weak to finish without some serious concentration. Our trainers are then instructed to tickle and tease the trainee as much as possible, only stopping once the trainee achieved a climax~ At first most trainees fail this test completely exhausted from the intense tickling sensation and pleasure, however after a few sessions the trainees usually learn to focus on their pleasure through the tickling sensation – causing them to become extremely horny whenever they’re tickled in the future~
