Your feet seemed to have pressed up against a massive pocket of air, and a feeling of dread creeps up your form as you try and struggle against the moist rippling innards of the vulpix's bowels, but it doesn't seem to help you at all, even with your fingers and arms pressing out against the tubing around you. Your feet continue to slip up and press against the pocket of air which moves a little closer to your form and presses up against you.
The little fox pokemon shifts and yawns a little again while he walks onward, trotting around the woods from which it found it's new little toy, much to your regret at this point, making sure the huge bubble doesn't burst while underneath you, the vulpix moves onwards, it's curled tails shaking and swaying around behind it as it looks around the area, sniffing at tree's and such before being contented with what it had sniffed out and walking on again.
You could feel the world squeeze around you, as though the little pokemon was no longer content with merely having you stuck in it's bowels and began using it's bowel muscles to tug you a little deeper than before, your body is squeezed and covered in the moist wetness that keeps the walls moist before your body is tugged a little deeper, you could feel your feet pressing further into the huge bubble of gas and your own squirms to try and avoid the obvious only seem to make things worse as the pokemon stops and shudders a little, seemingly wondering why it's little toy is being so active at the moment.
"Vul?" You could fear down past the layers of flesh and fur while the the fox pokemon walks deeper into the woods, stopping along a tree while feeling the huge bubble shift and press out, almost escaping on it's own at this point. The vulpix simply decided to help ease it out, of course you would have a starring role in it as the fox splayed it's paws out and stretched again, using his anal muscles to pull you a little further in, your legs press in against the surprisingly resilient bubble before it presses inwards, and you hope against hope your legs don't do the inevitable, which obviously happens, with the stretching of the vulpix your feet press in enough that the bubble finally pops and you could feel the shuddering of the small fox going on around you again. "Vulpix!" were the words you heard from the pokemon as it's belly gurgled and churned and it's tails lifted up a bit, from between it's buttocks, it's pucker bulges out, and gives way to a slow, puttering blast that breaks the silence of the clearing, the puttering fart turns into a bellowing monster that rumbles out of it's rear, the lengthy blast continues coming out, powerfully rumbling and quaking out of it's hind end, and the wind tunnel it forms around you continues blowing off with gust and powerful swirls of air, despite yourself you don't move even as the powerful fart, finally after a couple of minutes of roaring out of it the fox pokemon's ass comes to a loud sputtering stop.
The orange fox shifts around, standing back up as another smaller putter comes from out of it's hind end and shakes it's tails around, the gassy cloud it left behind would stay for a while, and would very well ward off any other pokmon that would decide to step around that way.
You however...
