Sensitivity experiments (Pixiv Fanbox)

Lately we’ve been experimenting with all sorts of fumes and gasses that increase sexual drive or sensitivity of our trainees~ Right now we’re running a test with a hallucinogenic spore, that makes every nerve-end of the skin more sensitive to the touch by a thousand-fold. Of course, what better way of testing out if those spores work than testing it on a trainee with ultra-fine brushes. I’m not sure if we can conclude that they’re working just yet though... What do you think? Should we give it a few more hours?
