[ Rex has no choice but to get punched considering his position, especially as he finds himself rather fixated on Childe's reactions. Still, it doesn't really do much in terms of getting the Mafia boss off of him. In fact, it just encourages him to begin moving sooner than he would have. What he's done seems to have inflicted the shock and pain on the assassin as desired, enough that it does ease Rex's ire to the point he isn't pounding Childe into the desk with his thrusts. Besides, the other is incredibly tight for him, which already had him about to see stars before getting punched.

Nevertheless, Rex speaks quietly, something closer to his usual demeanor (but still pretty far from it) even as he rocks his hips to continue fucking the other. ] Are you disappointed? [ there're a few strained huffs before he speaks again. ] Don't worry, you're far too tight for this to go on long. You should be grateful.

[ for what he doesn't say. ] The less you struggle the quicker it'll be over with.
