She is going to introduce you to the finer aspects of ball busting
Hey, hubby! Glad you're awake! I thought maybe I used too much drug in your drink!
I bet you wonder why you're all tied up spread-eagled on the wall! Remember Kathy, here? My best friend from college. The "uber bitch with the cobwebbed cunt who just needs a good five hour ass rape to loosen her up"?
At least that what I though you said! Well, seems she's into something called "ball busting", and after talking with her, I felt that it might be good for you to remember who had the REAL power in this relationship! And it might be fun!
