Yussa's fingers tighten when he meets Caleb's gaze. His thighs tremble and he makes a more concerted effort not to make noise beyond is already heavy breathing. But he finds he can't stay silent.

"That's it," he encourages, because such work deserves some praise. Ridiculously, he's excited by the prickle of the other man's beard against his most sensitive places.

He finds he wants very much to get a leg between Caleb's, to feel the press of his hard cock against his boot. But given that his smalls and his trousers are only just down around his thighs, he'll have to save that thought. The last thing he wants is to compromise his balance or change Caleb's position when he is so thoroughly enjoying himself. With a little smirk, his free hand makes a vague gesture and Yussa whispers something that's lost beneath the bass thudding through the walls. But he has a piece of copper wire wrapped around his finger, and a few seconds later Caleb can hear his voice in his ear.

"You look like you belong right where you are," he purrs, managing to sound less breathless than he feels. "Do you want me to come on your face, Caleb?"

Seems polite to ask. Given the sheer skill and enthusiasm of Caleb's mouth, it's going to happen soon. Yussa can feel it building.
