The friend you pick up after you drop off your girlfriend; the interaction between you is not a sexual one, but she could destroy you with the information she's gathered about your life.
Hey life mistress, remember when you ran to get me more beer even though you couldn't walk? I'm sure glad my girlfriend was asleep

A whore that know the rules of being a worthless tramp. SHe knows that the married man she is screwing has zero respect for her, knows he only want/needs her for sex and "dirty" sex, this mistress also knows that the man will never leave his wife for a slut like herself. She knows her place that wife is always first. The mistress also knows that 1 day a week, no phone calls, no texting, no messages IS the only way to go.
The MOST important rule is to KEEP YOUR DAMN MOUTH SHUT! If a whore forgets even 1 rule, they are not a good mistress. If the whore forgets and talks about the affair she deserves to have the wife whoop her ass AND public humiliation so everyone who will listen will know what a worthless deviod human being you really are!
Man "ya, girl.......your such a good mistress, my wife won't suck my cock after I put it in her ass!"

"Thanks, sweetie for keeping your mouth closed when my wife called you, now open it and do what a good mistress does!"

"Shut up whore, I told you NOT to call my house you are NOT a good mistress!!"

A java teacher who is a very hairy for a female. Now some girls are hairy, but mistress america is on the same level of hairy as big foot or robin williams. The only difference between her and big foot big foot smells better, and knows more about computers. She is a poor teacher, and a hairy fuckin freak.
I cant see the difference between mistress america and big foot, but the smell gives mistress america away.
