Aventurine sighed and shivered a little as he pulled back the blankets, slipping into bed next to his lover. Ratio, who generally insisted on going to bed at a scrupulously reasonable hour whether Aventurine joined him or not, shifted slightly against the sheets but didn't open his eyes.
"Sorry about my feet," Aventurine murmured as he settled in. "I didn't realize how cold it was in my office until I stood up." It was winter in Pier Point, and while he didn't skimp on the heating bills or anything, the windows in his office still let out a lot of heat. Insulation could only do so much.
Ratio made a quiet, inarticulate sound of acknowledgement, and threw an arm over Aventurine. Aventurine watched his face as he frowned softly, eyes still closed, and pulled him closer still, gentle touches seeking out all the places Aventurine's skin was coldest and covering as many of them as he could in a firm embrace.
Aventurine let his own eyes close as well, as he relaxed into the hold and let the warmth of Ratio's body soak into his skin. He hadn't really expected anything else, but he could never quite take it for granted, either: this happened fairly regularly, since his own more slender frame lost heat more quickly than Ratio's broad and muscular body, and every time the response had been the same. The first time he'd crawled into bed with cold feet, he had expected his lover to flinch away from the sudden chill, to wait to embrace him until he'd warmed up a little. He'd been startled when Ratio, even mostly asleep, had instead clearly viewed Aventurine being cold as a problem that he was capable of solving, and proceeded to do so without hesitation.
But he really shouldn't have been, he thought, mind beginning to drift off to sleep. It was just so emblematic of the way Ratio was, the way he approached the world. When he was more conscious, he was quicker to put his own needs first, more careful not to give what he couldn't spare; but like this, his truest core instinct rose to the surface, and it was to use the resources he had available - an abundance of body heat, in this case - to help the person next to him who was in need of it. Without reflection or hesitation, without any concern for his own immediate discomfort. Just because he wanted to. More than anything, that was what Aventurine loved about him, once he'd finally been convinced to trust in Ratio's sincerity.
As his breathing slowed and sleep took him, Aventurine was already almost warm, cradled against Ratio's chest.
