Hello dirtygirl... The first thing I notice is how polite and restrained everyone seems to be, including you. This needs to be corrected, but first you need to clarify if you've included any body writing at all in your hard limits, or only writing others can see.
If hidden writing is acceptable, then you're to take a sharpies and write the word "cunt" over the top of your slit (which I hope you keep bald as a good slut should), "tit" just above each nipple, and "asshole" with an arrow pointing to it on your left ass cheek.
If it's not acceptable, then a little punishment is in order. Clamp your clit with a bobby pin, leaving it in place as you go to the local shopping mall, minus underwear and spend at least two hours there window shopping. You may go to the public toilet every half hour or so to release the bobby pin for a short time to restore circulation, but you may not cum at any time from touching your clit. Before you leave, buy a new supply of IcyHot.
Return home and and coat your nipples with IcyHot and masturbate, continuously for thirty minutes after removing the bobby pin, after which you may cum.
Take photos (without showing your face as per your limits) of either the body writing or bobby pin treatment, and post them along with a full report.
