Tickle turns (Pixiv Fanbox)

What a lovely new game~ First we select a group of trainees to participate, usually ones that know each other well enough to be familiar with weak-spots. Then the trainees play a round of rock-paper-scissors to decide who gets to go first. The first winner gets strapped down first and mechanically tickled for 10 minutes. Once the 10 minutes are up, the next winner gets to be tickled mechanically and the first trainee. On top of that, the duration gets increased by 10 minutes with each turn. The trainee that has the least luck at rock paper scissors at the end gets tickled by 5 individual people as well as mechanical tentacles for a total of 60 minutes~
