Unregistered

We just helped break a new couple into swinging. After a wonderful dinner follower by play and foreplay, we all got naked. The other couples wife and I started getting really friendly and in no time were engaged in a torrid sex session. My wife did the really nice thing of blowing the other hubby while he watched his wife get ravished by another male. Everything was great until the other guy blew his load without warning and my wife went off on him. My dick went limp in no time at the yelling and the evening was effectively a bust. We both went home feeling pretty bad.

I realize he committed a faux pas by not warning of the impeding release but honestly as a newby I think my wife should have just grinned and swallowed (or spit) without making a huge ruckus. She claims there was no excuse for his faux pas and that he should have worn a rubber if he new he was going to blow. What is the consensus out there?
