Re: Sex Mugen
No problem. Glad I can finally contribute in some way.
To answer your question, the minotaur at the bottom seems to be in development with Kasumi (also at the bottom). So they're only completely compatible with each other.
Start a VS or training round with Minotaur VS Kasumi. Then get Kasumi into any of the "B" holds with the horse (don't know if he has a name or not). While in the hold hit "down", "forward", "X" or "A" or "Z" to start some gang rape (the best kind of rape). You can then cycle between positions using the other two keys. Be careful though, if you don't cycle within a certain time fram Mintotaur gets sacked.
Once again, just going off of memory here - so let me know if I got anything wrong. Oh and the keys I listed above are in reference to the "A,B,C", "X,Y,Z" layout - so whatever keys you have them set to.
