A few days after his wife, who works for a life insurance company in Tokyo, went on a company trip to a hot spring, he found a sheet in the back of a drawer in her room that said "hot spring trip"! I watched it without my wife's knowledge, and to my surprise, there were naked men swarming around my wife who was inebriated! It was an obscene orgy on parade, which they usually don't do to me! I was quite angry, but for some reason, my pussy was still hard and I was so excited that I even ejaculated. Another wife, whom I did not know, also fell prey to the orgy!
