Many women do more than that when they're alone with themselves. But the contrived rules do not allow them to relax with a partner. It is not without reason they say, that a smart woman has it in her head, a fool has it in her mouth. I even know men who categorically reject such liberties.
Lucky chubby guy - a gorgeous woman on his dick. And I didn't think women like that would fall for the chubby boars!
