Usually we wouldn't keep you in the pediatric unit, but unfortunately we ran out of beds, so you'll have to stay here for the night. Don't worry; I'll take great care of you. To start, I'll stretch these latex gloves over my fingertips and past my wrist, retrieve a disposable diaper from the cabinet, and tape it around you with care. Oh, my... well, we won't be able to diaper you with such a strong erection, so I'll just take care of this for you. Trust me - I see this sort of reaction all of the time, and I'm very used to handling this situation. Just lay back and relax while I help. Once you've cum into your soft padding I'll be able to tape your diaper snugly around your waist, safe and protected for the night until I come back to change you in the morning.
