Every boy's worst nightmare

Other

One day myself and younger brother along with Grandparents stopped off at the beach on a warm summer Sunday afternoon. We wanted to swim but had no costumes so my Grandma said we could go into the sea in our undies. This was fine and we spent a good half-hour playing about and the fact that we were just wearing pants felt the same as swimming trunks anyway. Wasn't until we got out and walked up the beach past hundreds of people that I noticed because my briefs were white, then wringing wet, they had become completely see-through! I was about 12 then and just starting to develop and looking down to my horror, everything (pubic hair and all) was showing right through!!
