Dragon health studies (clean diaper) (Patreon)

Youth is something wonderful, but sometimes it can't be helped when a couple of good friends get a little excited while alone in a public but closed space.

Gabby was reading the “Fetish Encyclopedia” while Spike was looking for a book on old Equestrian Law and got inspired for some surprise fun. Hopefully no one hears their moans in the quiet Library!

They just let the things happen as both knew the other enjoyed it as much as they did.

Thanks to CurlyWolf/ Curlysaf94 for the idea and their support.
