     'John Thomas! John Thomas!' and she quickly kissed the soft penis, that was beginning to stir again.

2. (slang, archaic) A flunkey; a male servant.
   • 1869, The Home Monthly, page 383:

     We are disposed to think servants an ill-used class. Not only the parlor, not only querulous masters and mistresses, but the press, is against them, and finds its account in ringing the changes on flunkeys, menials, servant-girls, and John Thomases, confident in a sure topic, and safe from reprisal.
