It took him a few tries, rhythmic bobbing that left him almost panting for breath, one long throb of want all down his harness, but he got himself spread enough to better take the strain. Sure. So what if alpha was humoring him a little? He had a moment; he could do this.

The cage shivered to life around him, and Clu jumped in place with a yelp.

"Hah!"

It was closing down on him, or he was pushing up on it: his cock wanted out and could not get there, the nubs rolling against him until every beat of his own blood was like a separate touch. It was the fine sharp drag of fingernails that wouldn't press down, wouldn't hurt him, but also absolutely were not letting him up all the way.

It was so tight.

"Ah," dragging in air only to try it again, pure frustrated hunger, "aaah!"

His head rolled back, throat jumping under the leash as he shifted restlessly. There was nothing to follow, no way to keep count or really anticipate what was coming, just always more. Pleasure looped up his spine, down, back and forth, nowhere to go that something wasn't thrumming through or against him. And he couldn't quite grind down on it like he wanted, like he needed, hips driving for that last inch of pressure almost by instinct. If he bore down, even just a little, it was game over.

Then alpha snapped the last switch.

"Oh," low, rough, like it was knocked out of him. He panted, mouth open, unable to make another sound until something wavered free from down deep, and that something sounded suspiciously like

"Oh, shit."
