Oh my goodness this is fun. Now I want you to put on a pretty thong, something that doesn't hide these labels. If you're comfortable wearing a plug while moving around for a long period of time, you should put that in too.
Write across your thighs "Spread Wide". Then see if you can get "Fuck Deep" on the back of them, so that they'd be right-side up if someone were to throw you onto the bed and bend your legs up over your head.
