A friend fuck my wife in front me and his grilfriend

Last weekend we invited a couple to our house, we enjoyed the pool. My wife asked our young friend to put the tanning cream on her. The boy went crazy running his hand over that huge buttocks and began to masturbate. My wife realizing that, invited him to sit down and gave him delicious oral sex; That's how a nice party started, where my wife fucked the boyfriend in front his girlfriend, proving to all of us that she's a real man-eater.
