One day I asked my (then - now ex) g/f to wear my underwear to work under her skirt so that all day she would think about my cock - that I was going to impale her with later that night. She said she would but only if I wore HER G-string thong so all day at work I would be thinking about her pussy which she said she would bury on my face then open wide for my dick.
I figured I "had" to do it since I asked her first. Her thong was super tiny (and barely fit). Just having it on kept me hard almost all day and when I got hard the top stuck out from her thong. I have never been more horny in my life and we fucked more than night than most people do in a year.
So doing something unusual can make for a very fun time.
