"Another cupcake, cupcake?" Pinkie asked sweetly as she came around the table with a tray filled with rainbow-frosted cupcakes. Sitting at the table, Rainbow Dash nodded, licking her lips greedily.
"Sure thing, Pinkie." Dash reached out for the cupcakes, but grunted as she found shifting over too difficult. The reason why, of course, was that even when she was sitting up on the bench Pinkie had gotten her, Dash's big blue belly spread her legs apart and anchored her to the floor. When she had hooked up with Pinkie a month ago, she had originally thought it'd just be her typical casual relationship, a real friendship with benefits kind of deal. But then they hit it off so well, and Pinkie was so much fun to be around... they had spent more and more time together, and in that they had started eating together. Even Dash couldn't keep up with Pinkie's nearly magical metabolism, and she had started spending more time with Pinkie and less time advertising. Couple that with Pinkie's apparent kink with feeding other ponies, and things had begun to spiral. Yet Dash, in her own way couldn't be happier.
"Let me get that, silly. We don't want you straining your little tum-tums!" Pinkie cooed, though there was nothing little about Dash's "tum-tums". It was, however, stuffed to the brim, so Dash happily leaned back. Pinkie got up on two hooves, standing beside Dash's belly and resting one hoof on it as the other fed Dash. Dash wasn't oblivious of her weight so much as she couldn't seem to find time to care. Whenever she had been about to exercise, Pinkie Pie had suddenly popped up with something more fun (but lower energy) to do. And when Dash complained, Pinkie would just start kissing her and telling her how wonderful she was. It was excellent for Dash's ego. So she had put on a little weight, big deal? If it was this easy to put on, it had to come off just as easily, right? She was sure that, any day now, she'd get back into shape. In the meantime she was enjoying life, fully indulging her lazy side.
Pinkie fed Dash cupcake after cupcake, slowly stroking Dash's belly as it inflated with more food. The pegasus was in complete bliss, and Pinkie couldn't be happier either. She watched Dash chew, extra chins wobbling, with lust in her eyes. After a couple dozen cupcakes, she decided enough was enough. Too full, and Dash wouldn't be able to have fun with her later tonight.
"All done, Dashie." Pinkie told Dash, nuzzling her bloated fillyfriend. Dash sighed and patter her belly. Then she tried to get up. She couldn't exactly throw herself up by her back legs like most ponies would, so instead she leaned around her big belly and got a front hoof down on the bench, which groaned despite the reinforcement Pinkie had recently added to it. From there she pivoted around her belly slowly, her mass of fat rolling on the floor. Upright, Dash's belly still touched the floor, requiring her to drag it along. Or at least it would, if Pinkie didn't have plans otherwise.
"Oh Dashie, you can't go back home all full! You'll get a cramp!"
"Huh?" Dash asked, slightly out of it from her sugar-binge and full belly. Pinkie giggled and planted a kiss on Dash's cheek.
"Don't worry Dashie. I got an extra big bed for the both of us! It's as comfy as any cloud." Pinkie replied, guiding her stuffed lover to the giant mattress she had set out. She had laid the mattress directly on the floor, as getting up on the bed proper would probably tax Dash far too much. There'd be plenty of time for Dashie's 'exercise' later.
