There was almost a sense of relief when those teeth finally came out of his neck, a small strain of panic he hadn't realized he'd been holding on to. Yes, it had felt amazing and he would do it again, but this was still... A unique situation and definitely heat of the moment actions. As much as he wanted to think it would make him more careful, there was honestly no chance of that.
His hands came up as Amadeus kissed him again and he took in that taste of their blood dangerously mixed together. One settled on his cheek the other tightly in the elder's hair. Ariel fell into the kiss like he could devour the Elder through lips and teeth and tongue alone. The only time he broke or slipped was when a particularly hard thrust dislodged him.
Ariel's hips met the other's just as steadily and forcefully. He could feel his nose scrunching up, the itch at his fingertips that wanted to become claws, the desire to throw Amadeus onto his back and, at the very least, rip into the mattress around them. That was not the kind of control he needed to lose but it was there, waiting, and evident in a growing, occasionally stilted, bestial growl.
