She gets her borrowed swimsuit stolen right then in the open.

As she thought of the current situation that she had at hand, Yukiko knew knew that she couldn't just return back to Rise and Naoto empty handed, and tell that their stuff all had got stolen, for she had made a promise to help them, and she couldn't leave them naked on the vast ocean.

"Alright, 'sigh', i suppose i'll have to think of something", she said to herself with her hand in her chin, as she began to think of a solution while she walked around the beach, where she tried to come up with a number of different ways to help her friends, included but no limited to, bringing them towels, or just buying a couple of cheap swimsuits at the local shop.

However, her thought process would soon be sharply interrupted as she walked next to a young girl, who in just a simple statement, managed to stop her dead on her tracks, "Ehhh, Miss ?", she asked nervously to her.

"Yes ?", Yukiko reponded, "Emmm, why are you naked ?", asked the young girl bluntly, upon which, Yukiko looked down in instict, only to recoil in horror upon seeing none other than her bare tits and muff completely exposed to the eyes of the girl, confirming her worst fears.

"Nyaaaa..., w-what.., w-why..., h-how did this h-happen ?", exclamed the red faced Yukiko as she covered herself in shame, wondering about how the hell did she lost her swimsuit, and thinking about how will she be able to get out of this.

Meanwhile, nearby...

"Heheheh, looks like operation bikini fall has proven to be a total sucess, garw!", muttered Teddie as he inspected his latest catch.
