“Hmmh, well, if getting me hot and bothered was Vinyl’s goal with suggesting this, well… I’m shamed to admit she might’ve succeeded.” The soft hiss of a hoof pump filled the air as the grey earth pony forced the last couple puffs into the large soft rubber ball, the valve on it’s side letting off a small hiss as the hose was removed. Pressing at the vinyl with her hoof, the valve was eventually sealed, the pump set aside as she rested back on her haunches. The slight squish of her belly as she looked down at it reminded her of why she’d asked Vinyl for some help in the first place - fun as it was being all swollen and puffy, the relative inactivity didn’t do much for helping her retain that lithe figure of hers. And while magic certainly would be an option, the least she could do for herself is attempt to shed this pudge on her own…
 
Taking a breath, the cellist rose to her hooves, rolling the ball around slightly. She certainly wasn’t entirely convinced on how this would help her lose this belly, but something was better than nothing, at least. Placing her forehooves on it, she pushed forth with her rear ones, feeling the rubber squishing around her belly as the air inside took her full weight, a slight chill running up her spine. Oh, it almost felt as though she had puffed her own belly up again… mmmh, musn’t get distracted. Letting off a sigh as the moment passed, the cellist continued to move herself forwards on the ball, feeling it pass her chest and belly, beginning to straddle it with her haunches.
 
With a gentle shove, she pushed herself up into a sitting position, steadying herself ontop of the rolling ball somewhat, feeling her rump squishing into it. Placing a forehoof beside her for stability, she let off a light chuckle, pressing down into it for a moment to feel the air shift around, wiggling her hind legs. Well, exercise or no, at least this is a little enjoyable too. She bounced herself slightly on top of the ball, starting to move and shake her hips around, feeling it roll and rock underneath her, the rubber squishing against her accordingly… up until she felt herself move just a bit too far.
 
A quick moment of panic overtaking her, one of her forehooves shot down to the front of the ball to steady herself, pressing firmly into the rubber - and then rubbing along it. The squeak reached her ears, certainly, but the pounding of blood in them quieted it somewhat as a blush crossed her face, the motion also having the effect of making the mas of airfilled rubber beneath her vibrate heavily. She took a moment to regain herself, looking down at the ball, and lifting her forehoof from it. Tentatively, she moved it back up on the patch of rubber in front of her, between her legs, and pressed down again - and, again, it rubbed, squeaked, and caused quite a pleasant tingling sensation.
 
“As if one fascination weren’t bad enough… heh, I suppose at least this one will have me moving, all the same…”
