I remember reading somewhere mares can go into heat if you shine a black light on them. I just thought that was interesting. I don’t know if it’s true or how it works but there you go.
“Being in heat means I’m going to be having sex soon. Not with you of course, you are a human. You told me humans hate to have sex with ponies because we are filthy animals or something like that, so I couldn’t possibly ask you. No, I mean with a stallion. Or maybe two. Or even more. As a Princess, I have a closet full of stallions I can use at any times. I might bring some of my friends along to join me. Heck, I might invite the entire town to join me. Everyone but you, Anon. I know you’d be much happier that way, with your sexless life being a human and all. All alone in the town while everyone else is enjoying sex. We’d ask you to join the orgy, but you know: ‘ponies can’t feel love like humans can’ and all that.”
Well then Princess Twiley, might I suggest that you go find a pony to copulate with, as they would be far more compatible than me, a human?
Alternatively, if you have a spell that can transform me into a pony permanently, I would be happy to oblige. :)
