Disclaimer: I do not own~ Naruto at all =)
For someone who has frequently been described as the "Ice Prince," Sasuke truly despised the cold. He had always had poor circulation, so the cold affected him more than it did everybody else. Not that he'd ever let anyone know that of course. Sasuke wasn't one to reveal his weaknesses to others - even if during the winter, it was quite difficult to suppress the shivers.
In all his 18 years of life, Sasuke had never once had to worry about someone seeing him shiver in the mornings when he gets out of bed. It was something that any normal human being has experienced - you roll out of bed in the morning, and your body instantly freezes. There's an almost instinctual urge to turn and crawl right back under the covers and go to sleep. Sasuke, despite being thorough in everything that he did and never allowed himself to be late for anything, fell prey to this often.
It was just an ordinary morning, much like any other. The alarm interrupted the darkness of a new day, and Sasuke mechanically sat up in bed and shut the thing off. As he scooted to throw his legs over the edge of the bed, shivers raked his entire frame. Teeth chattering, he automatically slid back under the covers and burrowed himself deeply into the mattress.
But there was something slightly different this morning. Unthinking, he nuzzled closer to the source of warmth on his bed that usually wasn't there. Silently, Naruto Uzumaki slid a strong arm around Sasuke, engulfing him in warmth. Sasuke felt his entire body stiffen. He'd forgotten that Naruto was there.
"I didn't know you got cold so easily," the blonde dobe commented, yawning widely.
"...Whatever."
But Sasuke didn't pull away from the other boy, and Naruto wasn't about to let him go.
