How many guys out there have this good of a girlfriend!  A girlfriend who will setup a surprise threesome for you like this one that was submitted to I Know That Girl.  Not only does this guy get to fuck another girl while his girlfriend watches but his girlfriend is getting her pussy eaten while he watches that’s a team right there!  It might be that this girl is a bi-sexual so every once in a while she just likes a girl licking her pussy and that’s probably fine with this guy since he gets to fuck another pussy every once in a while.
