Yazawa Nico was laid out on the chaise, under the beach umbrella, on her stomach, facing the ocean, watching the marvelous in motion Nishikino Maki race in and out of the waves. Maki, bikini top and board shorts her outfit of choice, waded in, water past her ankles, then raced to the beach as the surf surged, lines of tiny sandpipers on either side of her with the surf sliding underneath their progress down the beach. Maki laughed, throwing her head back, red hair catching the breeze, then half crouched, ready to race to the edge of the water and then away again. Totally oblivious to any audience, even Nico. Which Nico had come to realize was a core Maki trait. So Nico took it upon herself to glare at anyone who stared too lustily at Maki. And Nozomi would not be invited anywhere near Maki in a bikini top or any kind of bathing suit.

Maki had stopped, the water up to mid thigh now, and was waving at Nico in an inviting fashion.

"C'mon. It's fun."

"Nico is fine."

Maki ran up the beach, waiting until she got near Nico to shake out her hair, water droplets flying everywhere.

"Hey, knock it off, Nishikino."

"Why even bother with a swimsuit if you're not going to go in the water?"

"Fashion." Nico smiled. "And Nico is protecting her complexion."

"Nico is very boring."

"Nico spends a lot of time on keeping her skin youthful. You have no idea of the secrets of the Japanese and Korean beauty industries that Nico is privy too."

"It's summer. Play in the waves. Act your age. Not like somebody's grandma."

Nico flipped over, aware of the attractions her frilly pink swimsuit added to her curves, "Make me."

Maki's grin was practically evil and before Nico could react, Maki had scooped her up and was trotting into the surf. "Okay."

That was unexpected. Nico should have expected impulsiveness, considering how they met. And Maki carrying her somewhere. But Nico wasn't just going to let the mischiefmaker get away with that.

"Hey, put Nico down." Nico pushed against Maki's shoulders.

"Nope. You said "make me."

"And now I'm saying "put Nico down."

They were in the water. Up to Maki's waist. Nico should have considered where Maki was taking her before being so insistent. With a truly wicked grin, Maki held out her arms and let Nico drop.

There was a Nico sized splash. And spluttering. And cursing. And Maki's roaring laugh. And then steady hands making sure Nico was solidly on her feet.

"I am going to throttle you."

A wink. "Have to catch me first." Maki dove into a wave, swimming parallel to the shore.

Nico grabbed at her, but didn't stopping or slowing her. Nico stood, arms crossed, considering, waiting for Maki's next move, which was to turn and swim halfway to Nico.

"You can swim, can't you?" Maki pushed wet hair out of her eyes, sounding concerned.

"Nico can do anything."

Maki grinned. "So you'll…"

With a shout, Nico threw herself in Maki's direction, managing to get both arms around her waist before Maki reacted. Squatting, Nico managed to drag Maki back under the water, both of them twisting through a roll and then breaking the surface, giggling.

Nico released Maki. "It's your fault Nico needs to redo her sunscreen now."

"Oops."

Nico shook her head, "Race you to the chairs."

"I'm not helping you put on sunscreen."

"Oh, yes you are."

"Why?"

"Because Nico can whine all afternoon about salt water and her skin."

"Demon."

"Nico prefers nymph."

Maki splashed Nico.

"Hey."

"If I'm going to have to reapply your sunscreen, I might as well get some fun out of it."

"Touching Nico is a privilege."

Maki suddenly loomed, her arm pulled back, then pushing forward to tap Nico's shoulder gently, before diving through a wave that crashed over Nico. "Tag. You're it."

"MAKI!"

Maki treaded water long enough to stick out her tongue, then began swimming.

Another game Nico didn't intend to lose.

A/N: Femslash February prompt: swimsuit. I miss My Fly By Night Flirting AU so here's a little bit of silly to add to that.
