When perfoming sex in the doggy style position, begin to pull on the mate's hair. When the time is right, yank a sufficient amount of hair out and begin to intertwine and create a rope. Stick this in her mouth, as if it were a reign. Use this to maneuver and ride your partner around the track of sex.

This piece of hair must be from last night's Kentucky Derby.
