That's Not Why

Her lover told me he wanted to watch her cum before he took her....he wanted me to make my wife cum for him....it was a special kind of humiliation that I felt as I knelt before her and did my best to give her an orgasm that would impress him and delight her!!!!
That wasn't why I was nervous.....when he pulled up my skirt and pulled down my panties I was exposed and vulnerable as I tried not to let it distract me from my assignment!!!!
Then I heard the unmistakable sound of his zipper opening.....and I wondered....what was coming next!!!!
