A/N: Done for the Hetalia Prompts group on dA. This month's prompt was summer.

Can't say as I'm happy with this, seeing as it's my first time writing about these two, nor is this an original idea. I'm not entirely displeased, though, since it took me about an hour, and more or less makes sense...to me. As for why I chose these two, well...everyone else I know in the series are otherwise occupied in other fics of mine, and these were the only other two I cold remember seeing properly in season one. There's probably major OOC-ness going on here, since I really don't know these characters, but I thought I'd give it a shot. Apologies. OTL

The Attraction of Summer

Summers in Switzerland were generally moderate. Over the course of those few months, there might be a handful of hot days, a smattering of cool days, but overall, the climate was warm. Enjoyable and comfortable to the Swiss population.

Today was an exception.

The temperature was an unheard of 36 degrees Celsius. The air shimmered with heat. There was neither breeze nor shade from passing clouds. The sky was a pale, unblemished blue made paler by the glare of the sun. Sprawled inelegantly in a lawn chair, Lili covered her eyes with a forearm, unable to look at the sky for long. She soon removed her hand, and turned instead to look at where her brother stood several feet away. She sighed dolefully, hoping he'd take the hint and go inside. As long as he was out in this heat she felt compelled to keep him company; she didn't like it when they were apart for too long.

He was uncharacteristically dressed in a sleeveless undershirt and a pair of thin tweed trousers, the hem of which was rolled to his knees. He was barefoot, another irregularity. He stood perfectly still in the grass of his lawn, watering it with the garden hose.

The mist that sprayed up from the hose caused a faint rainbow to hang in the air. From her position, the rainbow seemed to arc from her brother's stomach and out into the air, where it faded to nothing. This whimsical thought pleased her. The sight lent a slightly magical air to her brother's somewhat stuffy disposition. A tiny, soundless giggle brought the fingertips of one hand to her lips. Vash was not the type of man to inspire such girlish fantasies…or fantasies of any kind, for that matter. But as she continued to watch as he frowned worriedly at his lawn, she took a good long look at him.

His shirt was soaked from the mist. His skin, where it was exposed in his chest and bare arms, was fair. It glistened. Small droplets of water ran down his arms and shoulders. Seeing this, an odd feeling of weightless unrest settled in the pit of her stomach. Her small smile faded away.

Actually her brother did inspire fantasies, from the moment he'd stepped in and rescued her. Fantasies and dreams that she was careful to keep to herself. But something about the hazy heat, and the rainbow, and the way tiny droplets of mist occasionally hit her face made her ache with her private fantasies now. She bit her lip.

"Vash?"

He glanced in her direction, looked away, then glanced back. "What are you staring at?"

"You."

"Well, stop it."

"You're handsome."

"…The heat has gotten to you." He made a point of turning his back on her to water another section of the grass.

"I do feel overly warm…" What was she doing? That was much too forward. But seeing him, his bare legs, she felt reckless. Suddenly wanting him to know how she felt, she blurted, "Come cool me off."

His brow lifted as he considered her. He looked at her for a long time, holding her gaze until she had to swallow her rising fright that he did know of her secret feelings. Her shameful and secret infatuation with her own brother. Her heart was very loud in her ears, and his green eyes were all she saw, all that existed. A slow smile curved his mouth as he turned toward her, and she thought, He knows! Oh God, he…he feels the same! It was the answer to all her unrequited dreams of forbidden passion, dreams she hid behind her sensible demeanor. She rose from the lawn chair now, ready to receive his embrace, to bask in it, to-

Cold water drenching her put a screeching halt to that line of thought.

Vash chuckled quietly to himself at her loud cry of shock. The look of outrage on her face was priceless. She was completely soaked. He watched her trying to smooth the water from her dress and found his eyes taking in the fascinating sight of her breasts. Her nipples were now visible through the wet linen.

He turned away again and pretended to be focused on the grass. He'd been uncomfortably aware of her in her sleeveless summer dress even before he'd pulled that stunt. She did not usually go about in such a revealing state. The skirt of the thin white material reached to just below her knees, displaying surprisingly shapely calves. How she'd reclined in the lawn chair, in such a casual posture, had allowed the dress to ride up and show her smooth, dimpled knees. Her throat was shiny with sweat, and the way she'd sighed often in the heat had made him grit his teeth with nervousness. He was not a nervous person.

He'd been aware of her stares. Her hero worship of him was cute, but had never displayed itself as staring. Today was different. She was different.

And he was her brother, not some uncouth beast like Francis or Antonio to letch at his own family.

He set his mouth in a tight line, and began to shut off the hose. It was high time they both went back indoors. Not even noon yet, and the sun was-

A hand slid lightly up his arm, to his shoulder, and rested there as its owner came around to stand in front of him.

She really was breathtaking. Usually so like him in so many ways, just then he thought she'd never looked more different, more...alluring. Her eyes were shadowed by lingering anger, but something darker stirred in them. They glowed up at him with green fire. She was wet, but not disheveled. No, she was somehow lit from within, alive with promise. Her skin was pink from either the sun's heat, or the heat within her. Her breath fanned out from her parted lips, scented with the mint lemonade she'd been drinking. It drew his gaze to her lips.

He was not a man of strong desires or particularly wayward thoughts, but as a breeze finally blew over them and tossed the hem of his sister's wet dress against his calves, he was suddenly unable to breathe. When his eyes found hers again, there was a knowing expression in them, an invitation. There was acknowledgement of things he'd thought he was alone in feeling…and this knowledge stunned him.

Lili let her hand drop, and Vash was able to draw a breath at last. He seemed unable to look away from the pretty way she tucked a stray strand of hair behind one ear, or the charming slope of her shoulders. Her bosom was modest, but there, hugged by wet material and enough to swell the front of her dress. The gentle sway of her hips as she walked across the lawn and into the house held his complete attention until the door shut softly behind her.

-oOo-

He looked down at the hard, long length in his hand that leaked moisture steadily from its tip. He looked back up at the house. Technically speaking, he wouldn't be wrong. And as her protector, the only protector she really had, a valid argument could be made for the rightness of it. He was her savior…it seemed proper now that he should be everything else to her as well. Honestly, he did not mix with many people if he could help it. No one would even know. It would be private. A family issue.

The hose was throttled and twisted until it leaked no more, then tucked away in its proper place. As he walked purposefully toward the house, one thought played over and over in his mind.

Lili wasn't his sister.
