One of the sexiest words in the English language has to be "Unbuttoning".
This weekend why not hunt down your most buttoned garment, maybe a shirt or a dress, and put it on with nothing underneath. Then tell your partner that they will be rewarded each time they please you with the undoing of a single fastening, and the gradual revelation of your body.
You could make it into a game, – perhaps a button will be undone if your lover manages not to utter a sound as you undress them. Maybe a button will be un-popped if they can stay statue still as you kiss them from head to toe. ..
