It was a nice quiet night at the campfire for Jaune and Pyrrha. Jaune was sitting nice and comfy, propped up by a log with a blanket over it, while Pyrrha was putting together as many s'mores as she could. It seemed weird making all of them in advance, but it made the next part much, much simpler. Once she had every last marshmallow, graham cracker, and bit of chocolate combined into a massive stockpile of s'mores, she set about feeding them, one by one, into Jaune's hungry mouth. Each mouthful he munched through made his jowls and chubby cheeks wobble and jiggle. Each s'more made his belly bigger and bigger, as it slowly worked its way out and out, spilling over the waistline of his cargo shorts and pushing his plain navy blue t-shirt up and up, revealing more of his blimp-like belly by the mouthful. By the time Pyrrha was done feeding Jaune, his enormous belly was so big, it was larger than Pyrrha, if Pyrrha curled up in a ball. That was an impressive feat, as Pyrrha was a tall young lady, and it showed what an exemplary job the polycule had done in fattening Jaune up and increasing his stomach capacity.
With Jaune well-fed, Pyrrha reached over and, with a little bit of help from Jaune, lifted his shirt off of him. Pyrrha then clambered up so that she was resting atop Jaune's massive, bulging, tight belly, as she sunk her hands into his moobs, which she was almost certain were bigger than her own breasts. Once she was in position and caressing his moobs, she moved in to make out with him, which Jaune was more than happy to reciprocate. As they made love to each other, one of Pyrrha's hands began to wander down, running over Jaune's vast belly, until it reached Jaune's shorts. As she began to tug on them, Jaune made noises, muffled by the kiss, to try and get Pyrrha's attention, before breaking off the kiss.
"Uh, s-sorry Pyrrha, not tonight. I'm way too full for that," Jaune groaned. "Guess there is such a thing as 'too much of a good thing'. Pyrrha's eyes shot wide open.
"Oh, goodness, Jaune, I'm sorry, I didn't realise," Pyrrha quickly responded. "Don't worry, I'll make sure Nora doesn't try anything tonight. Hopefully Ren is enough for her for now."
As disappointed as Pyrrha was, she didn't want to overwork poor, overfed Jaune, so she went with the next best thing, she scooched off of him and snuggled up by his side and rested up against him. She rested her head on his generous moobs and reached her hand down to his belly to rub small, slow, gentle circles to soothe his stuffed belly. Pyrrha cooed sweet praise to him as Jaune put a big, chunky arm around her, holding her close as they cuddled. Comfortably, they sat there, enjoying the warmth of the fire, when they heard the other half of their polycule having some fun out in the woods. Pyrrha might have been a little bit jealous, but she knew that Nora was almost insatiable, so she'd be able to have some fun with that thick little cutie.
A little while later, after the sounds stopped, the trees rustled and Nora, who was clearly not wearing a bra under her snug tank top or underwear under her excitingly short miniskirt, burst forth. The front of her was lightly covered in dirt, showing that Nora had at least made a vague effort of brushing the worst of it off.
"Guess who just got laid!?" she sang triumphantly, jumping up and making her generous breasts and burgeoning potbelly bounce as she almost flashed the pair. She was just in time for Ren to come waddling out after her, his massive rolling gut pouring out over hastily tugged on track pants and his shirt lightly stained with sweat, a thin sheen of which could be seen on the rest of him.
"Nora, you forgot your underwear," Ren panted as he held up the mentioned pink garments.
"Eh, it's fine, I think I'm gonna have round two," she replied, eying Jaune and Pyrrha up hungrily while Ren pocketed the underwear to make sure they weren't lost.
"Not with Jaune," Pyrrha cautioned. "I… stuffed him a little too full."
"Yeah, I'm not really up for it," Jaune groaned, rubbing his achingly full belly.
"Seriously?" Nora whined. "Some of my best orgasms were when I was stuffed to bursting! C'mon Jaune, you gave me some of those orgasms, you should know."
"I know, I know, I'm just too stuffed to be active," Jaune said apologetically.
"Well, speaking of stuffed, Renny, sit your big sexy ass down, I'm gonna feed ya!" Nora ordered. Ren shrugged and took a seat while Nora rummaged through all the food packaging. "Empty, empty, empty… Guys, where's all the food?" Nora complained. In sync, Jaune and Pyrrha sheepishly pointed to Jaune's tight, globular gut. "Nooo! Guys, c'mon, now Renny's gonna waste away!" Nora whined, shooting over to the supersized young man, sinking her hands into his fat belly.
"I doubt I'll even drop below a quarter of a tonne," Ren commented, taking a handful of his gut.
"Oh, don't worry, you're gonna have the biggest breakfast ever tomorrow morning," Nora cooed to the big boy she was now cuddling. With that, the big boys got plenty of cuddles that night, as the fire died down and the four of them eventually made their way back to their cabin for the night.
