Son helps Mom let her Hair down on vacation.
Mom and son are on a beach vacation. Mom is an uptight career woman.
The couple go clothes shopping and briefly separate. The son heads back to the changing room he last saw her at and hears his mom moaning and uttering, 'faster' and 'harder!' The son opens the Door only to see it is just someone mom got to brush her Hair. The son breathes a sigh of relief, but the seed has been planted in his head. He is starting to like the idea of his mom sexual proclivities.
Over time, the son sets up guys to flirt or try to hook up with his mom while he watches from a distance. He uses knowledge of his mom's personality to give her suitors an edge.
