Something was up. Surely she would be full by now, or at least would’ve moved and poked him to stop. And yet, as the next breath passed from the pegasus’ lips to those of the Cellist underneath him, she hardly stirred in the slightest. He slowed a bit with his puffing, breaking his firm concentration to open his eyes, shifting his weight atop her. Well, she certainly still looked to be asleep, or whatever the state of thought somepony who gets flattened goes into, and she didn’t quite feel firm as a pony should, either. As a matter of fact… moving his hips about, he found that his haunches were fully pressing against hers, legs only meeting with soft, airfilled ones. Perhaps he had gone overboard without noticing… a bit of movement caught his eye. Her left foreleg shifted, hoof squeaking across the soft floor. Well, she can still move them, at least… maybe he ought to keep going, just to be sure.
 
The cellist let off a gentle sigh, careful not to disturb the pegasus puffing her up too much as she did. The softness of her body as it slowly filled with air, the feeling of his weight squishing down against it, it was simply too good to stop it so soon. Besides, she had confidence he knew what he was doing, and would probably stop at a reasonable point… though, a small part of her most certainly hoped that he wouldn’t. He did seem to be resuming that old pace of puffing he had going after that little adjustment, so maybe he was waiting for her signal, perhaps.
 
Hopefully he wouldn’t mind too much if she were a bit… delayed, in giving that~
