Yukio rolled his eyes as the bed dipped gently next to him and arms slid around his waist. What was unmistakable, however was the smile that found his lips.

"Rin, what are you doing?" He asked, already knowing the answer.

"It's cold." The older twin mumbled, his arms tightening around Yukio.

Yukio attempted to suppress a chuckle in vain as he turned around in his brother's arms. He returned the gesture, pulling Rin close against him and resting his face close to the demon's own. Rin returned Yukio's warm smile and closed his eyes, his entire being relaxing considerably.

As Yukio watched his brother's breathe even out, he stroked Rin's hair and held him firmly around his mid section. He was warm and soft. Definitely a brilliant stress relief after all of his exorcist work.

He gently ducked his head down under Rin's chin, taking in the familiar scent. Yukio settled himself there, his face ever so slightly pressed against his brother's collarbone.

Rin made a contented sound and pressed his face against Yukio's hair, curling around the younger slightly.

"Your hair smells good, Yukio." Rin mumbled into the brown locks. Yukio made no response, as one wasn't needed.

The two just lay there, curled against each other's warmth in the middle of the night, content and completely relaxed. Just plain comfortable.
