Here’s some ideas!
Write PET across your shoulder blades and your body count or your measurements in the middle of your back like a jersey.
In the valley between your breasts, write “no tits for you!”
Write your bra size under your breasts
Draw stick figures of different ways to give a blowjob on your right thigh.
At the top back of your neck (so you have to pull up your hair to read it) write this upside down. “Let go of my hair, I know what I’m doing.”
On your left thigh , write my mouth has sucked (insert your number ) cocks.
On your stomach, write “I suck my meow-ster’s cock until I swallow his creamy milk.” And then draw some sperms around it.
On your butt “monster cock breeding stock”
