The Dark Pony
A note to anyone who likes my pics of showing sound effects of peeing but no pee itself: You won't find those by searching "wetting" anymore because the proper tag for images like those is "implied wetting", so make sure you search that if you want to see more. Also it seems such pics fit in the "safe" category as long as it's not sexualized or no pee is shown. I must say I was surprised to learn that and hope no one gets too weirded out by them.
