Personally I like to watch a girl get fucked in the ass, mostly so I can stare at her pussy. But I do love me some good old cumfarts, that shit drive me bonkers.
Shemale is good sometimes but I'm very selective about it, I don't wanna feel gay about it so its gotta be a really good looking shemale pounding a girl, and as long as I don't see the shemales asshole its all good.
Babysitter fantasies are nice too.
