There was my wife with fresh cum dripping down her top

As I walked in to the restaurant, I stopped, utterly stunned! There was my wife, whom I dropped off mere minutes ago, with fresh cum dripping down her top!

I looked around, but I could see no guys nearby! She acted as if it wasn't there! What could have prompted her to let some guy shoot his load on her like that, then just sit there, nonchalantly? And what the hell should I do about this...?
