The fact that Joseph kept from touching him for so long was both a good thing and appreciated. Not that he didn't want his lover to touch him, no, that wasn't it at all. If he had, Rhys would have become distracted and lose his focus. By the time he did, though, he was already bottomed out, his back arched and head back. There was something so different in this feeling, especially with the way his thighs were being petted, as if to encourage him.
It took him a moment of enjoying being filled and stoked at the same time before he started moving again, trying to find the thing that felt the best. He was already making some noise with each movement, each little stroke of that thumb. When he found the right angle of his hips along with the right depth? He cried out a little more, chasing those exact situations. To brace himself, he kept his hands on his lover's thighs behind him, arching his back to keep it.
