Revenge
You open your mouth and begin to lick your wife's pussy. You love this woman so much and you begin to feel bad for cheating on her. All you can think about now is that damn marriage agreement. Lisa leans back and begins to kiss Carrie. They are lost in each other again like you're not even there. Lisa isn't even moving while you are licking her pussy. You try harder and slide your tongue into her. Still nothing....
LISA: (looks at Carrie and gets off your face) I'm sorry, I just can't stand glancing down and seeing this loser's lying eyes looking up at me.
She turns around to face away from you and lifts her leg over your head and mounts your face again.
LISA: That's better. Tomorrow night he'll be licking Bob's cum out of my pussy in this position! Now where were we?
She then starts kissing Carrie again and this time she is responding to your oral attention. She cums in even less time then Carrie did and slaps your balls as she does.
(Slap your balls)
After a few minutes, they both get up and tell you not to move. They grab their clothes and walk into the other room leaving you for a few minutes.
