Public answer for this one ^_^ I wanted to say something on it. There are a few options:
A: There’s the Rubez2525 NSFW pony pack. You can find that one on Derpibooru right here. 

B: There’s the one I made, which isn’t available. I’ll probably put it out if I ever make it not behave like garbage. I’ll probably make it a follower milestone or something to encourage people to reblog me.

C: There’s an illicit secret one that’s been nothing for drama for me since I obtained it and subsequently never used it but am embroiled in controversy nonetheless! I’m willing to bet you can find it if you look around/ask around. The committee of the vagina protectors has advised me to never distribute it at the penalty of living out my life as a donkey in Equestria/being sent to the moon.
