It was the funiest and sexiest thing that me and my girlfriends ever saw and still remember it like it was yesterday. It happen last summer while enjoying a day out under the sun. Sandra and I were with our boyfriends and they had brought along their friend Mike. Mike din't have a girlfriend, so I invited Vicky to come along. Mike had one of those baggy surfers suit on and we were all making comets on how they keept sliding down on him. Every time he went in the water, he flashed half half the crack of his butt. Laughing at him just brought up the idea of yanking them down. I'm a sucker for a good prank and surprised that every one else wanted to do it. Mike was in the water and we were sitting on shore planning the whole thing behind his back. Vicky was al ready blushing and couldn't belief we were actually going to do it, but din't seemed against it either. Sandra, Vicky and I would stay sitting on the beach and would call him over to set him up. Our boyfriends were in the water along with Mike waiting for the right moment. Mike walked up the beach with our bofriends right behind him and pointing at him. We asked him some silly questions just to keep him standing in front of us, completly unaware of what was about to happen. His suit came down so fast, we were face to face with a naked Mike with his dick two feet away from us. He just said !oh shit! as he quickly pulled them back up. He sat down red as a tomato watching us roar with laughter. He most have been dying inside with embarrassment and had know other choice but to try and play it down. There was nothing we could say to make him feel better but to joke about and Sandra's coment "next time ware undeware" din't help at all. It turned me on so much, I wished they had taken his suit right off and making him plead to get them back.
