No Noise Challenge (Pixiv Fanbox)

It’s easy being loud during training. Just ramp up the vibrations, add some pain or stimulation and you’re bound to get some noises~ What’s way more difficult is staying quiet during the ordeal of a training session. Here we see a trainee with their arms tied above their head and a gag added to their mouth to add discomfort. We told her to avoid making any sound at all costs to avoid punishment. Should there be any noise, even the faintest moan or groan, the training will be declared a failure and the trainee sentenced to punishments~ What we didn’t tell the trainee, however, is how long she must stay quiet. The session has been going for well over an hour now and she’s past beyond her goal of 5 minutes, though it’s so much fun seeing her struggle~ I wonder how long she’ll last~
