One of my favorite things to do when I go out is analyze couples from afar. I can usually tell how new or old a relationship is, and how long it will generally last.
I can also tell how long that funky little sex will last, honey. Ironically, the couples who hang all over each other in public places are the ones who go home and serve up 7 minutes of some of the most tired, little funky ass sex you will ever witness. Think Kim and Ray-J.
On the other hand, those couples that seem to have a quiet chemistry, an understanding, good conversation and lots of laughter, are the ones who are going home making us all jealous.
So, the next time you're out in public and some couple is slobbing each other down, don't fret, cause if she's lucky, she's about to get 7 minutes of tired thrusting, then he's going to sleep on her.
