As the name already implies, white cotton panties are undergarments manufactured from cotton and are white in color. I had our honeymoon, and then noticed that I had no underwear on underneath and still felt excited by the exposing I did at the pool. Hula Hooping with no panties, the ex-girlfriend of Rob. I guess that is why she always had it made there. I'm losing it over this entire thing, my sister does not wear panties.
