Not to be confused with Pantyhose, Tights, or Leggins; Stocking start at the toes and continue up to the thigh. There are basically 2 types; Thigh High Stay Ups (have a built in elastic band to "stay up") and true Stockings. True stocking are normally 100% nylon or silk with no elastic bands. They require a Garter Belt to keep them in place.
Stocking are usually worn with a skirt and provide the ultimate tease to men when they get a glimse of the tops.
Stockings and high heels will always be the ultimate in "subtle sex appeal" for a high class woman.
The action of using an erect penis to "dock" with a pink sock (blown out asshole).
My boss' dog was walking around with a pink sock, he must have crapped something big. Anyway, my boss, Luigi, got an erection and tube socked the poor dog. -Tube Socking
