This event took place in late June 1998, on Lake Sognsvann, only about a kilometre from the Student's Village where I live. It was late in the afternoon (around 7-8 PM), and the weather was very hot, so there was a lot of people there. I had been for a swim at a secluded place away from all the people, had changed into dry clothes, and was just hanging around by the lake, enjoying the nice weather. The closest I had come to seeing anyone else getting wet with their clothes on was a rather good-looking Pakistani girl playing with some kids in the water. They were tossing a ball between them, and this girl, wearing a t-shirt and rolled-up tracksuit bottoms, was standing in ankle-deep water, getting the lower couple of centimetres of her trousers wet.
Then my eyes fell on a small pier a bit further down the lake, where two girls were playing with a young kid. I ran discretely down there. At the time I reached, the girls (which were probably cousins or half-sisters, or possibly just friends), had stopped playing with the kid (which was probably one of the girls' kid brother), and sat down at the edge of the pier. The girls were around 16-18 years old, and they both wore white sleeveless tops with bras and blue jeans. They were barefoot. The "pier" was floating on the surface of the water, so as the girls sat down (with their feet in the water), the lower parts of their jeans got wet, but none of them seemed to mind. Suddenly, to my surprise and excitement, one of the girls stood up and went over to a short swiming-ladder. She climbed down the steps and into the water, with all her clothes on, but instead of taking a swim she climbed up again, and now the other girl stood up too, and then both of the girls suddenly just jumped in the water. There was a group of students sitting at the pier also, a bit further towards the shore (both boys and girls), but none of them seemed to mind. When the two girls climbed up on the pier again, it was obvious that they had enjoyed what they just did, because one of the girls said, "let's jump in again!", and so they did. By now, a battalion of armed riot police couldn't have dragged me away from that place, turned on as I were by the great look of these two girls in their soaking wet clothes (their bras being clearly visible through their thin tops), and the fact that they did this before the eyes of a lot of people, not seeming to mind at all! As the girls climbed out of the water for the second time, they called to the kid (which had been playing in the shallow part of the water for himself while all this went on), and told him that they were going for a swim. I discretely followed them as they walked towards the "beach"-like part of the lake, and overheard them commenting on the look and feel of their wet jeans as they walked along. As they reached the "beach", they just walked straight back in the water, still with all their clothes on, right before the eyes of at least twenty people, and spent a few minutes playing in the water with the kid (one of the girls even did handstands in the half-metre deep water!), before telling him to stay in the shallow part, as they went for a swim. They then set course for a small "island" about 75-100 metres out in the lake, the water in between being so deep theyhad to swim around 1/3 of the distance. After splashing around a bit, and briefly going ashore on the "island", they swam back. They waded around for a bit, and played some more in the water (they didn't do any more handstands though), before finally going up. I went home from the lake as a VERY happy guy that evening.... ;-)
