Well, since you're having monsters, it might be nice to try to differentiate your story from other ones by trying sentient creatures that people don't usually use. I mean, I don't think I've ever seen a Manticore in one of these. Others right off the top of my head that aren't as popular or overdone are almost all the classical mythology monsters with the exception of Minotaurs.

(Hell, been a while since I've seen a Satyr in on these...)
As of right now your story is pretty generic, with hot gal off to get laid by monsters in a fantasyland. Might be nice to give her an explicit goal, once she's there, even if that goal is as simple as "Figure out how to get home!" Off the top of my head, you could always have it revealed that her fantasies have caused her naughtiest dreams to come true, and as a result it's a constant battle to not give in and surrender to the dreams.
Other than that, Good Luck, and Good Writing.
