As Sun and Neptune lay together in their shared tent, inside a destroyed sleeping bag, there was a sense of defeat between them.
"I… uh… I wasn't this big last night, was I?" Neptune asked, his arms having to stretch a little to meet atop his enormous gut.
"I wish," Sun replied, reaching a hand over to rub circles on the side of Neptune's hefty gut. "We'd gotten you a little thick, but you definitely weren't this big. And they got me too," Sun added, moving his hand to pat his out potbelly, which had smothered his formerly famous abs.
"Looks like Sage and Scarlet won this prank war, we lost big," Neptune sadly admitted as he sat up. Doing so made his rolling fat body wobble and jiggle like jelly. Neptune even reached with a thick arm to support his new c-cup moobs and keep them under control.
"I dunno," Sun disagreed, "I feel like the real winner here." He extracted himself from the shredded sleeping bag and clambered up on top of Neptune's belly. Sitting on it was like no other seat Sun had ever sat on, being so soft and sinking so far into it. The best comparison he had would be to an under-filled waterbed. "We've been working so hard to get you fat, and Sage and Scar do our work for us. Plus, I get to join in. Maybe we should try and score some of their stash, make me even bigger," he bragged, patting himself on his thick rear. As he did, Neptune noticed the small splits in the seams on the sides of Sun's skin tight boxers, which were strained even further by the bulge that was pressing into Neptune's massive gut. That was when he also noticed that his own ballooning behind had blown his off, leaving him nude beneath his tattered sleeping bag and concealing blubber belly. All that gave it away was the hard blush that was coming on.
"Oh, man, I kinda wish we'd sprung for a private cabin," Neptune nervously joked. A look of realization hit Sun after a moment.
"Sounds like everyone else's problem," Sun said with a confident smirk. He leant down, lifted Neptune's head up by his jiggling double chin, and gave him a long kiss on the lips. After that came 'everyone else's problem', as Sun and Neptune came too.
