It was cold. No, cold was an understatement. It was freezing and Rin was not at all happy when he woke up in the middle of the night, frozen from his head to his tail. He shuddered and rolled over, trying to find warmth in the blankets piled on top of him. From next to him, Rin could hear Yukio sleeping soundly, body basically radiating heat.
Yukio was surprised when he woke up to find Rin curled up into his chest. Not only that, but he had managed to pull all of the blankets off of Yukio and onto him. He flinched when something icy touched his leg and realised it was Rin's tail "bastard must be freezing" he thought. Yukio smiled and pulled Rin closer to his chest, placing a hand protectively over his head and began to slowly run his fingers through Rin's hair. Something of a purr escaped Rin's lips and he shifted under Yukio's touch.
Suddenly icy hands slid around Yukio's waist and he sucked in "Rin!" He coughed "Rin wake up!" He nudged his brother in the side and Rin stirred "ngh... What is it Yukio" Yukio rolled his eyes "your hands are freezing, Rin, take them off my waist" he replied through clenched teeth. The icy hands withdrew and Yukio was left with two cold spots on either sides of his waist "how do you stay so warm Yukio?" Rin asked drowsily. "How do I stay warm?" Yukio thought "I don't know, but you always feel like you've just been swimming in ice". Rin chuckled "Well your a furnace all days of the week Yukio".
The boys lay there in silence until something tickled Rin's nose. "Rin" Kuro put a paw on his eye "Rin I'm hungry". He groaned "there's food in the fridge Kuro, get it yourself". There was an unsatisfied snort from Kuro but Rin felt her paws settle on his chest. His hand fumble around in the darkness, eventually finding Kuro's ear. She began to purr and the vibration almost put Rin back to sleep. His eyes fell shut and he was awake just long enough to feel Yukio's arms pull him closer and wrap around his chest.
