It's the sound of Caleb's voice, the quality of it, as much as the words. And as he finds his stride, Yussa shivers beneath his touch and he feels a delicious throb as Caleb's fingers press closer together, trapping him between them. His breath shivers and Yussa moves his hips, as if he needs to remind them both that he is still full of his lover's cock. He's already swept up in the slow build Caleb is encouraging. Yussa closes his eyes.

"Is this how it will be?" he asks with a sound that is almost a laugh, but it's too breathy. "I'll master you by day, and you me by night?"

Oh, he certainly expects it to be more balanced than that - he has every intention of mastering Caleb by night, as well. But this is talk, and he's already enjoying it. Surely this is just anther way to encourage... developing creativity. And he quite enjoys the fantasy they can build every time they do this.
