Accidental See Through
The other evening my wife and I was at a party. She had a low cut thin dress, but against my reccomendation she chose to also have a thin bra on. Still slightly see through but not enough.
When the party ended and we went back towards our hotel all of a sudden a heavy rain started and we became very wet. When we came into the hotel lobby I realized that in the rain my wifes dress had became totally see through.
It was a very uncomfortable experience but compensated by the view of my wife standing very visible in a completly see through dress and bra with erect nipples in the hotel lobby. But we rushed to our room to take off the wet and cold clothes.
