I once had a set of board shorts that I used as a pair of swim trunks one day....they were yellow and didn't have a liner on them.
I had been playing football on the beach with some of my ex-gfs cousins and I made a dive for the ball into the water.
When I got out of the water and walked back to my ex-gf, she just hugged me tight and as I looked up, all her cousins were red-faced and acting kinda wierd. Her and I went to a hammock to relax for a while and that's when she told me that she could see all of me right through my board shorts....
Now that I look back on it, I guess the rest of them were jealous of me or something, whatever.
Too bad she isn't my gf anymore, she's missing out on ALOT of potential!
