So far, so good. Izumo pressing back up to meet him caused his own noise to leave his throat, quiet but very real. The hands fisted in the sheets gripped a little tighter. Five minutes ago he was worried about this person leaving him, whether it be by death or his own will. Now, all he could focus on was how alive he felt like this, how alive and connected they both were. It was a comfort he didn't know he could get, but now that he had it he wanted more and more of it until it filled him up to the point of bursting. He lapped at Izumo's tongue, the slick friction causing a shiver to run down his spine that ended in his abdomen, causing him to grind down again, this time with a bit more confidence.
His lips moved to the corner of his partner's mouth, then down to his neck, which was quickly becoming his favorite spot to memorize. His scent was strongest here; no amount of shampoo and soap could truly wash away the smell that was just Izumo. He inhaled deeply as he kissed just under his chin, warming a spot before sucking up a bruise. His shirt would cover up the marks, but part of him wished it didn't. This person was his now, and only his, and he was proud of it.
A warmth spread over his skin, pooling in the hollows of his throat and chest, fleshing pink across his face. The places where they touched sparked like a live wire, from the smooth slide of their mouths to the warm pressure of his hips. Izumo arched up into him, friction grating heat between them, another throaty moan escaping him. As Kotetsu broke the kiss, his fingers pressed into his scalp, worrying dark strands in between them.
Tongue darted out to lick his lips, still tasting sugar and Kotetsu on them. At the open, damp pressure of the other’s mouth against his throat, his breath caught, head automatically tilting back. “Kotetsu,” he breathed, rocking up into him once more. Part of him wanted to be annoyed at the fact that’d there be marks later, but the rest of him got a thrill out of the idea that he could look in the mirror later and be reminded of how much he was wanted.
