"Oh pooie," Pinkie says, examining her depleated pile of sweets, "We've got nothing left but crumbs. Now the only sweet thing left here is you!"
She punctuates her point by giving you a playful slap on your new second chin. It's barely noticeable but it's there, a flabby bit of extra skin on your neck. Not to mention your gut is still ballooned outward with half-chewed sweets. She pats your belly, and you jiggle all over, from your flabby chest to your thunder thighs, to your swollen milk sacs flopping lazily between your legs.
The motion causes your gut to start sloshing, and you feel a pressure rise up your throat. Pinkie hears it too, and leans in close to you, almost as if she's ready to give you a kiss. Suddenly, you're caught off guard by the powerful urge to belch, and let one fly right into Pinkie's face.

She belches, and you find yourself compelled to sniff it. Sour, but with a twinge of sweet. She smiles at your willingness, and rewards you with another belch. You hungrily sniff the slightly stinky air, and pull her in for another kiss. You shiver as you feel something soft brush up and down against your clit. It's Pinkie's hoof, she's pleasuring you as you make out.
You feel yourself about to blow, and you...
