It's past midnight when Justin comes into the bedroom, carefully quiet as he opens the door so as not to wake Giriko. The chainsaw went to bed hours before, after making some fuss about the priest boring him to sleep; it's not an unusual situation, at least, and as long as Justin is quiet Giriko sleeps through his entrance most nights.
He almost makes it. He gets the door open and shut and sheds his clothes in the dark without any sign of movement from the covers currently pulled up over the other weapon. It's when he leans in to climb onto the mattress that Giriko rolls over and speaks.
"Justin."
The priest's not sure that Giriko's totally awake, but an apology is usually the best way to stave off an explosion. "Hi Giriko." He pitches his voice deliberately soft, in case the chainsaw is mumbling in his sleep. "Sorry to have woken you."
"Mm." The sound is absent any emotional overtones, but when Justin pulls the blankets over him Giriko reaches out to grab at his hip. "C'mere." The chainsaw pulls hard and Justin doesn't have a chance to resist, even if he wanted to. He hits up against Giriko's chest and the chainsaw tips his head in to sigh against his hair.
"You're cold." That is faintly judgmental.
The chainsaw is much warmer than Justin is, radiating the heat of sleep into the blankets and Justin's skin alike. "I'm sorry. I'm stealing your warmth."
He moves to pull away but Giriko's hold goes tight and the chainsaw pulls him in closer. "Don't." He takes a deep breath and sighs again, like he's getting comfortable, and angles one leg over Justin's hip. "Can't get warm on your own."
Justin smiles into the darkness where Giriko can't see him. Then he turns sideways to face the other weapon, tucks his head under the chainsaw's chins and presses his mouth into Giriko's chest so the chainsaw can feel the expression even with the lack of light.
Giriko sighs again, relief and sleep audible in the sound, and half-rolls over Justin so the priest is more or less pinned in place. It's inordinately comfortable, particularly with the rapid increase in temperature it comes with. Justin hadn't even realized his fingers were stiff with cold until the heat hit them.
"Happy new year," Giriko mutters against the top of his head.
Justin sighs, and shuts his eyes, and smiles again. "Happy new year."
