Here are 3 comments on her covermyface.com scene:

cbzillia : mackenzee is so hot. great ass and such a willingness to get completely covered in thick nut.
CleanUpGuy : A good looking piece of ass. Talks a good game but when the seven guys start to come on her fucking face she wimps out. What a let down. Dumb pig.
beaker : Absolutely horrible. Best part of the scene was Brandon chewing her out.

I've paid girls less and got better performances. I've paid girls more but have never had worse performances. It's true: money doesn't buy happiness.
