Try before you buy (Pixiv Fanbox)

Making a large purchase without having tried the product before can be quite risky, which is why we love to give our customers the opportunity to see our services for themselves. Here we see a tester-trainee in one of our customer rooms. People passing through the dungeon or waiting for an appointment may feel free to make use of her however they want. Trainees in this position receive this kind of punishment for repeatedly breaking dungeon rules or not following orders. Usually, they’re stuck for a week before getting to rest a few days and re-evaluate their willingness to cooperate~
