lost my swimming trunks

I guess my most embarrassing moment would have to be the time I went out to the beach with my best friend Josh, his sister Tara, and her friend Heather last summer. He and I surf, so we went and did our thing and his sister and her friend were swimming in the shallow water. Anyway, on one particular wave that was a little big for me, I wiped out. No big deal, I'm not that good, so I wipe out quite often. I stood up and started to walk back up to the beach for a breather and caught the eyes of Tara and Heather and they immediately just burst out laughing and started pointing. I looked down and noticed that my swimming trunks were not where they should be! In fact, they were'nt even on me at all! I immediately ducked down in the water and started looking for my trunks and Josh joined in laughing. Then Tara and Heather thought it would be ny to go back up to the shore and grab my towel! I stayed in the water for a while and tried begging them to bring my towel out to me but they just teased a bunch, waving the towel around and saying, "No you're gonna have to come get it!" and giggling the whole time. Eventually I just bit the bullet and waded out of the water. Of course by this time we'd attracted a bit of a crowd, so I made Josh walk a little in front of me so as to shield me a little. Tara and Heather ran off with the towel lauhging hysterically and then Josh ran after them leaving me with no cover so I just ran as fast as I could to get away from the beach and to the car. Luckily Josh kept the keys in a little zipper pocket in his shorts. Knowing the girls they probably would've locked us out and made me run HOME naked. I managed to get my towel back from Tara for the ride home, but they made me sit next to Heather and she kept tugging at the towel trying to get a peak. I kept a VERY tight grip, but she kept pulling when I wasn't looking aand I'm sure she got a peek or two! I don't think she stopped grinning the whole ride home. FINALLY, we got back to Josh's house. I walked in and Josh's OTHER sister Katie and HER two friends were in the living room all just staring at me with a strange look as if to ask why I was wearing nothing but a towel, and just as I begin by saying,"I can explain," Heather grabbed my towel and pulled it right off of me in front of everybody!!! Well right then I decided enough people had seen me naked for the day and ran upstairs. I got dressed and left as quickly as possible. I try not to visit his house quite as often now, but whenever I do one of the girls never fails remind me of that day, as if there was any chance of me forgetting about it! Not to mention the fact that I go to the same school as all of them, so they and all their friends giggle and smirk at me whenever they see me in the hall. I think it's safe to say Ive never been so embarrassed in my life!
