Steam Heat

Riza shivered. Central was suffering one of the coldest winters on record, and her heat was broken. She huddled in three layers of clothing and two blankets, and Riza still couldn't get warm. Even Hayate was too cold to do anything except sit in her lap. She sighed. Enough was enough. She refused to freeze in her own apartment because her landlord was too cheap to get the heat fixed. There was a place she could go, and Riza had given up on trying to talk herself out of it. It was a risk, yes, but she'd rather take it than freeze to death.

Tucking Hayate inside her coat, Riza wrapped a scarf around her neck and face and pulled on a hat. She was already wearing gloves. Locking the door behind her, she ventured out into the cold, snowy streets. Thankfully, her destination wasn't that far away, and the city had kept the sidewalks shoveled to some extent. Riza managed to make it to the apartment building in under twenty minutes. It was easy enough to let herself into the building and make her way up to the apartment she was looking for.

She sharply wrapped on the door. It took a few minutes for it to open.

"Hawkeye, what are you doing here?"

"My heat is out, sir." She carefully pushed past him; she could feel the waves of heat radiating from his apartment. "I hope it won't be an inconvenience for you."

"Well, I can't let my favorite lieutenant freeze to death, now can I?"

Riza stepped into the warmth of his apartment with a sigh. Blessed heat. She removed Hayate from her coat and set him down. Hayate, happy to be warm, curled up in front of the fireplace and promptly went to sleep. Roy locked the door and turned to help her peel off her coat and the rest of her winter garments. He tugged the gloves from her hands.

"Your hands are freezing!" He took her hands in his, kissing each fingertip.

Riza let out a soft sigh at the heat his lips left in their wake. Roy wrapped her in his embrace, his heat warming her.

"I'm cold, Roy." She snuggled deeper into his arms. "Warm me up?"

He pressed his lips to her shoulder "And how should I do that?"

She lifted her head to kiss him. His lips on her own were enough to begun to warm her. "You're the Flame Alchemist. I'm sure you can figure something out."

Roy smirked down at her. "Let's see then."

He began to peel off her remaining clothing, pressing kisses to the skin that was revealed. Roy began walking her back towards his bedroom. He tumbled her into his bed. Riza curled into his covers, slipping under the thick blankets. Roy followed her beneath the covers. He pulled her into his arms, kissing her softly. His fingers drew patterns on her chilled skin, leaving trails of warmth in their wake. Roy knew exactly how to set her on fire. Riza slipped her tongue into his mouth. Their kisses grew more and more heated.

Riza rolled on top of him with a coy smile, her hair creating a curtain around them as she leaned in for a kiss. Roy lifted a hand to trail his fingers through the fine blond strands.

"Are you warm yet, sweetheart?"

She shook her head. "Not yet."

Roy smiled. "We'll have to fix that."

The next thing she knew, Roy had flipped them over so he was on top. His hands cupped her breasts, gently kneading them. He kissed his way down her neck and sucked one of her nipples into his mouth. Riza moan and arched her back. Roy took it as encouragement. His lips soon had her writhing beneath him, and his fingers stole down to stroke between her legs. Riza gasped.

"Stop teasing already, Roy."

He smirked at her and kissed her quickly then thrust into her. The two of them found a familiar rhythm, and soon the world exploded into white hot heat. Afterwards, Riza snuggled against Roy, warm and cozy at last. Shared body heat could do wonders. All in all this was not a bad way to spend a cold winter night.
