What is it about candle light that makes naked skin so much more appealing?
Could it be that the dimness masks the flaws that modern light amplifies? Is it just the mysterious flickering around the room?

The light of a candle darkens my wife's skin as she flushes with arousal. I can see her eyes darting beneath closed lids as she approaches her orgasm.

What is normally a bright pink tint to her chest, neck and face becomes a darker, more sensual color. Her body is all golden curves and silk smooth plains. The yellow flames cast dancing shadows as I watch her, as my hands move over her body...

Ahem.
Ok, then, here's what you need to do: Get a bunch of candles. The cheap tea lights you can buy bag fulls of work just fine, but we usually prefer candle sticks with holders. Place them all around the room, on as many horizontal surfaces you can manage. Try not to start a fire.

I think it is best to do all this in the middle of the night, after a bottle of wine and a comfy bubble bath, but whatever gets you going, you know?

You might also want a bit of music, if you can resist "getting the rhythm".

Of course the most important thing is the candles. Don't use the heavily scented ones, they are just too distracting when you need too be paying attention to your SO. Also, don't try to get fancy with the colors, there is no point.

It makes all the difference.
