Ann comes to save the day

"Hey, you guys!"

A familiar voice caused the two to turn towards the shore, where Ann was swimming towards them with a smile on her face. Futaba immediately paled and hid behind Akira as Ann swam up.

"Didn't think I'd run into you guys here!" Ann said. Her smile turned into a frown as she saw Futaba cowering behind Akira. "What's...going on?"

"U-umm...uhh..." Futaba struggled. Akira sighed.

"She lost her swimsuit." he said simply. Futaba looked at him in horror, and Ann gasped as she looked closely at Futaba.

"H-how did that happen?" Ann asked, then gasped again. "Oh! Was it that wave?" Akira nodded. "Well...what are you gonna do?"

"That's what we're trying to figure out!" Futaba cried out. The three of them sat in silence for a bit as Ann joined in the thinking time. Suddenly, Futaba made a sound of an idea.

"Ann, give me your bathing suit!" she said, and Ann turned red.

"Wh-what?! How does that solve anything! Then I'll be n-naked!" she said, glancing at Akira. Futaba shook her head.

"I can wear it back to the dressing room, get the spare swimsuit I brought, and then bring yours back!" Futaba said confidently.

"Wait, you brought a spare swimsuit?" Akira asked.

"You never know!" Futaba exclaimed. "I just couldn't think of a way to get to it, but now-"

"Wh-why can't I just bring you your spare?" Ann suggested.

"Well...I kind of hid my stuff..." Futaba said with a nervous laugh. "I...was paranoid."

"Then just tell me where you hid it!" Ann said, grasping at anything.

"I wouldn't be able to really explain it--just, please?" Futaba pleaded. "Just let me have your swimsuit! It won't take long!" Futaba gave Ann her best puppy eyes, and Ann stared at them intensely. Akira could see her resolve slowly cracking until she finally broke.

"F-fine!" Ann said. "J-just be quick!" she said, and reached behind her back. Before she could undo it though, she stopped and looked at Akira. Her face turned red again. "T-turn around please." Akira nodded and turned around. Her blush deepening, she undid her bikini and bottoms and handed them over to Futaba. It wasn't until Futaba had put them on that they realized a problem: Ann was...bigger than Futaba.

"U-uh..." Futaba said as she stared down at the bikini, which was a little big, causing it to hang out and almost expose her nipples.

"Are you sure I can't do it?" Ann tried one more time.

"I'm sure." Futaba answered. "I'll just..." Futaba undid the bikini, tightening it as best she could. When that still wasn't enough, she just pushed it up against her. Ann sighed. "It'll be fine!" Futaba said. "I'll be back!" And with that, Futaba swam back to shore, holding the bikini against her chest. Akira started to turn around, but Ann shrieked.

"D-don't!" she said, and Akira turned back. Ann also turned around, dipping as far underneath the water as she could. After a few moments, Akira couldn't help himself and glanced over. He could kind of see the shape of her ass through the water. Ann looked over and growled, causing him to once again turn back.

Meanwhile, Futaba was struggling a little with the bikini, as it made swimming a little difficult, both from trying to hold it up, as well as the water tugging at the loose bikini, loosening it. Once she made it shallow water, it became easier. She tightened it once again, and tried to discreetly push it up by crossing her arms. She needed to be quick.

She rushed over to the dressing rooms, thinking over where she hid her belongings. With that in mind, she grabbed at the handle, and pulled.

But the door didn't budge.

She pulled again, but it still didn't budge. She could tell it wasn't locked; it just seemed stuck. She grabbed it with both hands and tugged again and again, to no avail. It seemed to be stuck.

Well, there goes that plan. She could try to find someone to help, but that seemed kind of embarrassing with how the bikini was. She could just go back; she promised not to be long, but then they'd be back at square one...
