It isn't really so much longer til Archie follows suit, really. The general headiness of the moment, as well as the specific excitement to be found in both satisfying Horatio and having his husband quote poetry at him, is far too overwhelming in its own right. Combined with the kisses and touches, and it's simply impossible for Archie not to let go with an entirely ecstatic cry.

It's just as impossible, after, for him not to return Horatio's kisses with sloppy, slow, and entirely sweet ones of his own, a breathless "'ratio" occasionally falling from his lips.
