The training begins (Pixiv Fanbox)

Tickle torture is wonderful~ It always starts innocently enough: A new trainee is tied down, not really knowing what's going to happen. We love to leave them in that situation for a few hours, so their mind goes wild~ Then the process starts with a light tickling. At this point most trainees still believe this to be a joke and laugh away, not knowing about what awaits them in the upcoming hours. During the next minutes, the intensity increases, which is usually when the pleas for mercy begin and our training starts~
