I'll give two examples from the Samurai warriors series.
Okuni in her "Warriors Orochi" version is one of the few female perverts Ive seen in video games. She's a geisha and historically she was the creator of kabuki theater, but for some reason in the Orochi version of her shes... well for lack of a better word HORNEY! She's constantly flirting with all the male characters and says things like that she doesn't mind if the guy already has a girlfriend they can still "play around" and at one point she goes up to Sun Jian and Sun Quan (a father and son) and flirts with both of them saying she would take one in each arm. So we got someone willing to break up couples, and a possible interest in an incest 3-some. These are just two examples and there are many more. She's left me speechless a few times in the game.
The other one is a guy named Magoichi Saika. He's constantly flirting with any girl he sees even if they happend to be underaged (Oichi from samurai warriors 1 who he asks if she wants to go somewhere private) and in Warriors Orochi he makes it quite clear the hes only helping to save certain female characters because he thinks they are hot. Hes funny too but not quite as outragous as Okuni is.
I'm sure there are many other examples that people can list here.
