NSFW - But oh so very very hot

I don't know how to imbed this, but this link is about as hot as it gets.

But why? 
Why is this so incredibly hot?

I think it's hot she is wearing a wedding ring.
I love the sound of her breathing, it's almost a shiver.
The way her hips move up and down, fucking her invisible lover
The depth of her fingers
The color of her nails
The way the  her belly button ring catches the light.
The simple straight forward way in which she makes herself cum.
There is no hesitation, no drama, no holding back.

She has beautiful skin, a wonderful body, bright pink cunt and a wonderful touch.
I just wish we could hear her more at the end, that final peak.
 
Simple, Direct, and incredibly sexy.
