As with Nurse porn uniforms, you can dress up as your favorite superhero or pretend to be someone else, like a teacher, a firefighter, or a maid. Wearing sexy underwear already makes things more interesting, but putting on a costume would be the icing on the cake. You could take different situations and add a little sexual twist to them, like a professor about to fail a student unless she does him a little (sexual) favor. If that happened in real life, it would be crazy, but since you only do it in private, no one else is there to see how sick and twisted your roleplaying ideas are. Your girl can dress up as a maid who not only cooks and cleans for you but also sucks your dick whenever you need or want her to. When you tell her to, she'll bend over and show you her tight pussy. You're in charge, so she can't stop you from putting her in whatever sick position you want. People who work in construction wear hardhats, but they can also be worn in bed. You won't need hammers, drills, or saws, but you will need other tools that you wouldn't use to build a house to work on your girl's pussy, if you know what I mean.
