Letting Ariel have this one—for now—was worth to be able to hear those sounds coming from him. Maybe Amadeus should have been more concerned that Ariel losing control the way he did, and all those sharp teeth and claws, turned him on the way it did but he never even considered the fact. He just appreciated the fact that Ariel did let go now as compared to when they had first started out. That his lover could finally get lost in who and what he was. It was one of the reasons Amadeus would push his buttons so besides wanting to hear the sounds he could drawl out of him.
And Amadeus always did enjoy watching his lover move on top of him. Especially when he was lost like this. Not that the elder Kindred was idle. His hips thrust up to meet Ariel as he moved, even as he was memorized by watching the way the Gangrel did move. Keeping one hand gripping Ariel's hip, Amadeus couldn't help but trail his hand up that body again as it moved, feeling the muscles flex under his hand.
Those little cuts and slices from his claws hardly mattered. They'd heal once Amadeus allowed them to. He could have healed them as they happened but allowed them to stay for now, the sting of them just adding to the pleasure. To that release he needed to just let everything go.
