Skin color contrasts

I get severely turned on by watching my wife work my dick. The skin color contrast is mind-blowing. She's very dark. Her skin tone is dark enough to be African--equatorial African. I'm pasty as a white boy can be. So, there's my pink dick getting hard in her mouth. Her nearly-black lips form a ring on me while her dark brown face slides back and forth along my cock. Or her ass cheeks spread while my cock obviously slides into and out of her pussy--the contrast makes it unmistakable.

Anyone else find the skin color contrast to add to the sex?
