Conflict of interest (Pixiv Fanbox)

It isn’t easy for our male trainees to hold their orgasms until their trainers allow them to cum, especially if they have another trainee between their legs whose training goal it is to make them cum as quickly as possible. If she takes longer than 30 minutes to make him reach orgasm, she’ll be thrown into the maze as a plaything for our monsters. If he doesn’t manage to last 30 minutes of her stimulation, he’ll be sent to our milking farms where he’ll be forced to cum for weeks straight without any time to rest~ Having two trainees with conflicting goals, both trying to avoid punishment, is quite fun to watch, especially since there can be only one winner.
