This one is apparently a simulator, in fact, have a copy paste from the source:
Content wise it's been slimmed down quite allot. For starters, it will only have oral. Then when that is done, I'll see what can be done. But for now, just click the "swap" to look at a preview of the first two models done. Fluttershy will possibly get a "Trembling" model. And also, the finished product will have the option of "anatomically correct" and "human vulva" so those scared of anything else then dicks looking different xPThere isn't much, but the stuff there is nice to look at it. Have a look by clicking the link!
Pony Preview (No FA account? That sucks.)
