I'm unemployed, but when I went to help out at a hot spring inn run by a relative, a group of young wives showed up! As soon as they got into the hot spring, the young wives showed off their huge tits, which were so big they floated in the bathtub, and had a great time! I thought it would be dangerous if I was caught peeking at the scene, but instead they invited me to join them in the mixed bathing! In that situation, I couldn't contain my erection, and when the young wives saw my erect penis, their frustration exploded! They showed off their huge tits and asked for my penis over and over again, saying, "Just once!"
