It doesn't look like Shinjirou will come in time, not with the way Irvin is aggressively grinding forward, trying to lodge his knot even deeper into Shinjirou. Jade can almost see the exact moment that the dog comes. Unlike other dogs, Irvin doesn't swing around to face the other way; instead, his forepaws release their vice-like grip on Shinjirou and the dog throws his weight forward, burying himself inside the deepest yet as he begins to come, a constant stream that fails to leak out only because of the blood-engorged knot that plugs Shinjirou's entrance completely.

Jade lets out a breath he hadn't known he had been holding as Irvin goes limp, forcing Shinjirou to support his entire weight. The dog is mostly still now, save for infrequent little rocking motions.
