Eevee's Filling Out Her Costume (Patreon)

The Eevee looked at herself in the mirror, she loved dressing as other pokemon for Halloween, and chose one of her favourite ghosts this year! Gourgeist made for an excellent costume, glove hat and all, but she couldn't help but notice her figure didn't quite match it. searching through her masters' closet, she dug out an air canister, pulling it out of a collection of other inflatable pokedolls he had lying around in there and dragging it to the center of the room. Her curvaceous figure did look hot in the skintight suit, but she felt she could do better. Turning on the gas, she wrapped her lips around the nozzle and felt her cheeks bulge as the pressure squeezed down her throat. Her eyes fluttered from the lightheaded feeling of gas rushing into her, before feeling it pool in her belly and torso. She giggled knowingly as she felt her bottom beginning to billow in kind, as her whole lower figure began to round off in an adorable ball shape. Merrily she kept on sucking, her rounding off torso engorging behind her as it pushed down and out, her thighs flaring in kind as she kept on expanding. The suit grew along with her, made of flexible breathable material that slid well over fur as her ballooning behind put it through it's paces. The sounds of creaking rubber and hollow hissing emanated through the room as a deep blush crept across Eevee's cheeks, her pussy bulging along with the rest of her waist as it pushed out against the taut fabric. For a brief moment, she broke her kiss, leaning back and looking at herself before standing upright to find that she had added a good two feet to her height from her weather balloon sized torso. A gleeful squeal left her lips as she patted her big body, but the sound of the hissing tank still going in the room caught her attention once more. She looked down slyly, thinking to herself that THIS was a good shape...but even bigger would look even better right? After all, Gourgeist came in a lot of sizes... Leaning back over, she opened her mouth once more, nonchalantly wrapping her lips around the nozzle as she swelled and swelled.

Her master was walking back to his room when the sounds reached his ears, a muffled yelp and a hissing noise, eliciting a sigh from him as he picked up his pace to get to the room. Upon trying to open the door, he ran facefirst into it as it bounced back against him. Rubbing his nose from his stymied ingress, he tried again, but more firmly. As he did, he realized that it was being pushed against by something big and rubbery, only realizing too late the colour of eevee's costume on the balloon that seemed to be swelling. In surprise he called out to her, telling her to stop and asking what she was doing before beginning to try and push his way in. His Eevee was absolutely in her own world though, loving the expanding flesh of her body and the pressure of her figure beginning to reach the far wall. He pushed her to the side, shoving his way into the room and against her large warm body before sliding the door back shut, but the moment he did, Eevee shifted her huge rump and pinned him to the back wall. He was wedged up against his own closet doors and the plush warm flesh of his pokemon as she kept ballooning more and more massively, calling out to her to ease up and relax. His cries were muffled by the huge pneumatic wall of pleasure he was trapped against, becoming the hard thing stuck between a wall and a soft place...
