We were on summer vacation with a group of friends. In our first day on beach one of our friends decided she didn't want bikini rope tan lines. So she lay down on her back to sunbath with her bikini on its place but ropes untied. A little time past and she was still lying happily in half sleep.
At that exact moment I was sitting on the edge of our paddock and she was on the sun bed right in front of the paddock to get the full sun. I don't know what exactly happened but I guess one of other girls shouted her from the sea to join them. As soon as she heard her name was called to give respond she jumped from her place totally forgetting her untied bikini. So simply inevitable thing happened and her bikini top flied away exposing her handful perky tits just a meter way from my eyes. It took only couple of seconds for her to react and cover her boobs but that was already enough time to fully record her tits and nice nipples to my memory
