Long shot, since I have not been able to find this.
The story is an Eevee gets a new job at an office, all the other employees are Eeveeloutions. On day one, they wind up in diapers, and on subsequent days additional things continue to happen to them - each being triggered by one of the others in the office - before the big climax at the end.
Unfortunately I can't recall at all where I'd read it.
I realized I never replied to this. I think if someone could improve on the design so it required another person to actually trigger the deflation… yes I would have done much longer
For women, the Cather has a lot more length outside the body and I’ve found a large bandaid about 3 inches above my labia allows the catheter to loop all the way up then tuck into the non adhesive area of the bandaid and point downward dripping over my most sensitive parts
