This was starting to get a bit silly. He could feel himself not just resting on, but sinking into the cellist's swollen stomach now, her flanks ballooned up even moreso to be most certainly larger than his own at this point. And yet, she was still only lightly stirring, moving one of her back legs enough that his own slipped off of it's puffy form. Undaunted, the pegasus continued to push breath after breath into the mare underneath him, even as he started to really believe he'd gone overboard… up until he was surprised by a puff being pushed back into him, however slightly. Perhaps his own weight was pushing air out… yeah, that must be the problem! So, all he had to do was keep puffing, or at least puff a little harder. Taking in a deeper breath, the pegasus blew ever more forcefully to overcome the pressure, just feeling the cellist swelling more. Oh, hopefully he was right…

The cellist was surprised, to say the least. She tried so hard to keep that moan down, feeling her flanks and body swelling out, growing soft, squished down by the weight of the pony atop her, but as he shifted it simply slipped free. She'd half-expected him to take that as a sign to stop, much as she didn't want him to… and yet, as that swelling sensation grew ever so slightly more pronounced, she certainly wasn't expecting him to actually speed up with his puffs! She let off a softer moan in response, one that didn't seem to alert the pegasus, feeling the familiar sensations of pressure filling through her body, her ears even finally starting to balloon out. Adjusting her foreleg, a slight squeak escaped her as she felt it press against the side of the vehicle, the soft rubber squishing in against her equally soft swollen hoof. If he kept this up, she might very well end up so swollen inside here, they'd both be trapped…

…a not-insignificant part of her brain certainly didn't seem to mind that possibility, though…
