The following is artwork by  eskaria145 which he was kind enough to finish as the icon for his commissioned story. It features everyone's favorite big fat sass machine, Roberto, and his smol nugget of a girlfriend, Pety. He's given me permission to post this up and naturally, I've decided to add a mini-story to it like his other pieces because eskaria's my homie and he deserves nice things.

Roberto groaned lazily as he eased down onto Pety's mattress. His rotund, immensely engorged belly sloshed heavily as it rocked and swayed with the big frogs every movement. In response, a deep, gastric burbling emitted from Roberto's extremely bloated gut, causing the fat frog to grimace with discomfort. Then, Roberto threw his head back and expelled a forceful and wet sounding belch.

"BWWAAAAAUUUUUUURRRRP!!!!"

The abrasive sound rumbled up his throat for a few seconds straight, getting gurgle-y by the end of it. Of course, Roberto could feel another one bubbling up right after that. So he slapped his hand against his belly and expelled another, huge belch, one that was significantly louder and stretched out for a few seconds longer.

When it ended, Roberto sighed with relief then lazily ran his hand up and down his smooth, round dome, which had expanded to a solid four plus feet. Roberto's belly was so engorged, that it spilled well past his pelvis and could've neared the halfway point of his thighs were his thighs and fat tail not spread apart as he laid down. His long, reptilian tongue ran across his lips contently as he idly stroked his big, burbling midsection. "Ooohh, mierda...dude, you keep cooking like this and, oof, jodido infierno, I'm gonna be too fat to get outta bed..." Roberto huffed as his hands slowly ran up and down his beanbag chair of a stomach.

"You say that like it's a bad thing," Peti teased. The little four and a half foot tall bird girl flew up and sat down in the dead center of Roberto's pillow-y rubber mountain of a stomach. Her rump sank a good deal into the soft-scaled flesh, causing Roberto's belly to glorp and burble intensely. Peti's cheeks reddened as she looked down at the vast yellow belly all around her and eagerly planted her palms directly into the frogs churning middle, rubbing and kneading away.

Small as Peti was, especially when compared to the eight foot seven tall frog Tares, those tiny palms of hers never failed to bring instant, euphoric splendir to the gluttonous predator. Immediately, Roberto's eyes went half-closed as he eased back, groaning pleasurably. His large, gurgling belly stuck out higher, lifting Peti up along with it as he relaxed in her grasp. "Ooooooohhhh maaaaan, no wonder I haven't eaten you yet...who'd be here to rub my belly if my favorite little nugget was trapped inside..." Roberto cooed with delight, unwilling to allow his relaxation to keep a bit of sassy banter at bay. "...I'd be hungry in an hour anyway..."

"You'd miss me and you know it, fatty," Peti teased, still too smitten by the bloated mass all around her.

"...Yeaaah, maybe a lil," Roberto conceded with a shrug.

Peti just continued keeping her focus squarely on Roberto's belly. Her little palms pressed into the squishy, soft surface, tenderly caressing its rounded edges high and low. She even dug the clawed talons of her feet gently into Roberto's underbelly and kneading away like a bird would when nestling into a nest. This was enough to elicit a groan of contentment from Roberto, whose arms dangled to his sides.

At one point, her clawed feet pressed a little too firmly, and as a result, Roberto threw his head back and let loose with another slimy burp, one that sent a few flecks of slimy saliva flying out of his rippling maw. When it ended, Peti's fingers twitched eagerly. "You can do better than that," Peti insisted, before pressing her palms much more firmly into the dead center of Roberto's warbling belly.

"HOOOOOOOOOUUUUUUUUURRRRRRRRRAAAAAAAAAAAAP!!!!"

A massive, thundering belch exploded out of Roberto's maw, making the frog go wide-eyed as his mouth gaped open with his rubbery lips rippling intensely for several seconds straight. Peti, whose cheeks were redder than a pepper, could feel the pressure actually exacuate from Roberto's big soft belly beneath her palms as she pressed down. Her instinct was to press down even further, causing the crass sound to extend longer and louder mid-belch.

When it ended, Roberto gasped breathlessly and huffed a few times to himself, resting his free hand idly atop his heavily bloated gut. He would've made some snide remark, but he was too busy catching his breath to say anything just yet. His large belly jutted up and down as he shakily caught his breath, with Peti riding on top all the while.

"Got anymore in there?" Peti teased, eagerly pressing into Roberto's belly to work more gas loose.

"Hurr-BWEEEEEUUUuuuuuurrrp!!"

Another deep burp erupted from Roberto's maw, but this one, while still pretty good, lacked the force, volume and length of his previous monsters. Not entirely satisfied, Peti pressed again. Roberto opened his mouth, expecting another burp to come up, but nothing came up. Peti pouted and pressed even harder. A rather soft, low burp was pushed up, but nothing beyond that.

"Mmm, think you got 'em all," Roberto said with a shrug. He snickered with amusement at the little bird Tares disappointment. "Heh, no te preocupes, cariño. Give my gut a few minutes and I'll have more good ones ready for you to push out, ya kinky lil gremlin," Roberto teased, patting his belly heartily for emphasis, causing it to glorp and groan deeply in response.

"I'll hold you to that, you sassy gasbag," Peti teased right back, flustered and nonetheless eager to hold Roberto to that.

Roberto snickered with amusement. In truth, he still had absolutely no idea why Peti got all riled up anytime the fat frog stuffed his face like it was going out of style, or anytime Roberto burped loud enough to shatter glass. But he really didn't care one way or the other. It made his girlfriend happy, so he was more than happy to indulge her. Not only that, but the frog just loved eating, and loved even more the feeling of someone tenderly and lovingly rubbing his belly any time he did stuff his greedy face. Nothing in his life felt better than Peti's itty-bitty hands pressing, kneading and caressing his belly, especially when it was as engorged as it tended to be whenever she cooked for him. So as far as he was concerned, it was a win-win. He got to enjoy some damn fine eats and even finer belly rubs, and she, in turn got to enjoy all the noisy, sloshy byproducts of her labors...

Before long, she went right back to rubbing Roberto's belly in slow, soothing circles that required her to lean up against Roberto's belly just to reach it all. And Roberto, in turn, was once again putty in her hands; her adorably tiny hands. However, as Peti continued caressing Roberto's immensely rounded middle, she couldn't help but notice something as she felt Roberto's stomach up all over.

"Your belly is starting to feel even softer, like it's getting thicker," the bird girl mused. "Didn't think you'd start getting fatter so soon..."

"Whadduya expect, la monada? If you keep feeding me a fucking buffet, I'm just gonna get bigger and fatter each time," Roberto remarked dismissively.

Of course, the frog just rolled his eyes when Peti's face burned even brighter and she muttered, "Good...I wanna see just how big my tubby Robby can get..."

"Hmph, big enough that you ain't gonna know what to do with me after a while, querida..." Roberto remarked with a suggestive grin.

This caused Peti's feathers to puff out as her cheeks lit up like fireworks. But after a while, her feathers steadied and she grinned right back at Roberto.

"...Oh, I'm sure I'll think of something..."

The two shared a rather longing glance at one another, as if both were ready to get under the sheets and have some fun together. Then, unable to help himself, Roberto decided to break the ice.

"...Are you gonna use my belly as a nest? 'Cuz I can't lay still for however many months eggs take to hatch."

There was an immediately dull look in Peti's eyes as she once again turned to Roberto's belly and started rubbing some more.

"Robby, have I ever told you that you're an idiot...?"

The frog snickered, folding his arms behind his head and jutting his belly up even higher as he arched his back and yawned like a fat, rubbery lion.

"Mmph, you may have mentioned that once or twice..."
