>>1696568"... but still I just can't believe sensei actually made you wear it anyway," Natsumi was saying. "I thought that she'd at least let you wear your underwear instead. That's what she made Aki-senpai do last year when she forgot her swimsuit. I mean I only heard about it afterwards and all but apparently she said swimming in her underwear wasn't really any worse than swimming in a bikini. The real problem was afterwards when she had to walk home and-"
With a gasp Chidori looked up from her halfhearted efforts to stuff her breasts back into her swimsuit and exclaimed, "That's it! That's what I can wear!"
Natsumi blinked in confusion, "Huh? You mean your underwear? But I thought sensei made you..."
"No, a bikini!" Chidori continued undeterred, "Your bikini! Like you said earlier!"
Remembering her offer from earlier, Natsumi happily went through with it now, and the two girls quickly undressed and exchanged swimsuits. Natsumi slipped into Chidori's school swimsuit with no difficulty, while Chidori put on the bottom half of Natsumi's bikini. It fit fine, although she had to retie the strings that fastened it at either side. The top, needless to say, posed a bit more difficulty. It was strapless and bandeau-style, consisting of a strip of material with strings that tied behind the back. Natsumi helped tie it for her while Chidori tugged carefully at the fabric in the front, but despite her efforts it just wasn't wide enough to cover more than a small fraction of her breasts. Still, it wasn't nearly as bad as the alternative. Her breasts weren't being squished any worse than they had all day and they weren't bulging too badly, and it didn't feel like they were about to pop out at any moment. By the time Fuyumi-sensei arrived at the door and called everybody out to the pool to warm up Chidori had calmed down and was almost pleased with the solution she'd found.
