What is a side chick you may ask....
Well she's very similar to a mistress in that you will never leave your wife for her  with one major difference.....
I will never expect more. I'm nothing like your wife or your mistress. In reality we could never be. We're nothing alike. You're not my type and I'm certainly not yours. You could never introduce me to your work colleagues or you friends or family.  
I'm the woman you lust over at the gym, the woman you stare at in the grocery store.... you find you min wandering as you undress me with your eyes....wondering 'how does she taste?'......then you shake your head trying to free yourself from the idea of being turned on by a woman so...so..so....different.  
That's what makes me the ideal side chick.
I'm perfectly happy being your dirty little secret, unlike the mistress. I don't demand or expect gifts on holidays or birthdays. Your body is my gift. Besides how would you explain the those credit card charges for fancy dinners and expensive lingerie? That's just a argument waiting to happen, and I don't want to make your life hard, I want to make YOU hard.

 

 
You don't have to wine and dine me, in fact I prefer that we keep our trysts secret because there is something so hot about an illicit, clandestine affair.  

 
When we're together we're together and when we're not....well we're not.
I'm not your all American girl and I don't want to be! I'm the professional side chick, the one who's pleasure is derived from pleasing you.  

 
I want your body not your heart
