I'm I the only one that finds a girl with a flat smooth belly and unpierced navel sexy? I especially love to finger and tongue my girlfriend's navel, she seems to love it and tells me none of her previous boyfriends paid any attention to it.
Also like seeing girls in porn getting their navel licked, but rare it is. Vivid and most of the big companies, seem to ignore this part of their stars antatomy, or the guys in the splicing room cut it out. Seems right when the tongue is leaving the breasts and starts down the stomach, the camera looks up at the face, or it cuts right to cunt lapping. Some companies like VIv Thomas or Girlfriend Films seem to include a few good tongue in the navel scenes...but still far from common.
