Once you've finished, remove everything (rubber bands, bondage, clips/hanger - everything) from your tits. Now put your breasts into the icy water again for as long as you want, at least two minutes. All done? Good, you're so close to finishing sweetie.
Just one more thing. Remember the candle? Lie on your back (you might want to put down a towel) and cover each nipple (including aerola) in wax. Drip some more on top, then wait for a minute till the wax is cool to the touch. Now, peel it off carefully and you should be left with two little casts of your poor, abused nipples. These are to take pride of place somewhere in your home (e.g. mantelpiece, desk, somewhere people will see) for the next fortnight. If someone asks about them, it's up to you if you tell them the truth.
Don't want to put them in public? Then quite this tease now, well done for getting so far.
