Let’s give some good old vending machines a new spin: Introducing the coin-operated trainee display~ Its function is quite simple really: A trainee is placed inside the display and rigged with all sorts of toys that activate once someone inserts a coin. Not only can we humiliate trainees that way in public, but the machine also pretty much pays itself off. Maintenance is required once a week in order to clean the machine and refill the liquid feeding tanks or whenever the coin-collector is full though. It’s so fun to see a trainee go through all stages of humiliation and embarrassment when they can’t control themselves from orgasming while a group of people on the other side of the glass panel is cheering for their lewdness~
