Keith hears himself groan, a low and nearly growled sound as he finds himself pinned arms wrapping around Shiro to hold him that close, rising up along his back, shirt hitching up in the process. He leaves a final softer kiss to the mark he's made before leaning up to murmur straight to the other man's ear. "All mine..."

And then quieter, "All yours." It's a promise, and it's the simple truth, even if that truth is a realization that has only now made its way into the light.

Keith's eyes focus for a moment over Shiro's shoulder, and all at once his shoulders shake in a nearly silent laugh. "I guess it would be nice to have a bed right now..." Oops. Oh well. Still no regret. Not even a moment of it, for how this played out.
