“It has been a while since we have done this, hasn’t it dear?”

At the present moment in time, Cherry was resting atop her Mistress’s massive bulk. For weeks she had been eating, even when she didn’t have the fruit to fatten her up. Her massive size had just kept increasing. In the previous weeks she had been terribly excited when she had passed the Planetary Governors bulk. That seemed like a distant memory now.

Today however was different. Rotunda had devoured her latest shipment of fruit rather quickly. She wanted to go back to how she used to gain before, fattening foods that would bulk her up with pleasurable eating rather than cheating her way to bulk with an alien fruit. Her maid, Cherry leaned in, asking her one question.

“Indeed mistress. How would you like to begin?”

“The cakes please.” was all Rotunda replied. Cherry obliged, feeding the impossibly obese Rotunda a round of cakes as they were levitated towards her maw. The mare’s feeding had improved in rate too, the cakes vanished within mere moments.

Cherry herself had heeded her Mistress’s words from before and had been fattening up too. Not at quite the same rate, but she now was approaching a rather impressive two thousand pounds. It may not have seemed much on a colony of excess where a lot of ponies weighed far more, but often servants didn’t gain these sorts of sizes until the end of their tenure lest it got in the way of their work. Rotunda had been encouraging Cherry to gain though.

“Feels wonderful doesn’t it.” her mistress said, purposefully shifting her bulk against Cherry’s so the maid was almost smothered in fat as it oozed over her, Rotunda threatening to swallow her whole in her immense folds. It was more a statement than a question, both Cherry and Rotunda knew how the other felt about gaining in size.

“Indeed mistress. More cake?” she asked, levitating a few sponges upwards as Rotunda licked her lips in preparation for another round of decadence.

“Take a few for yourself dear, I need my prize maid to keep her weight up.” she grinned, watching as Cherry separated a few of the cakes and the two gorged together. It was one of those moments of sheer bliss, the two immense fatties chewing and rubbing their hefty guts together in pure enjoyment. The way Cherry was positioned on top she could hardly help herself from letting forth a little excited squeal as her massive flanks nestled themselves on top of Rotunda’s even more impressive stomach.

“We’re not leaving until I hit five figures and I’m not far off.” Rotunda said with a grin, her expectant jaw already unhinged as Cherry now levitated a number of cans of whipped cream upwards for them both, the majority going to her master again. It was something she had recently learned she had gotten a penchant for. Not that she minded, the mistress was free to eat what she liked. Besides it was more pure calories that easily went down. Cream was so easy to eat, so inviting…

Glug...glug...glug…

Blooooorrrrrrppppppppp.

Guuuuurrggggllllleeeeeeee.

Those two gigantic bellies filling with food couldn’t help but cry out in enjoyment. Such a wonderful stuffing as the maid and her mistress really enjoyed fattening up. It was the perfect few hours to spend alone together. Rotunda had sent the rest of the staff away and her husband was once again away on business. Nopony would find them being so naughty. Their fat bodies pushed and squished against each other as the two blushy and hefty mares partook in a mutual feeding that neither had been able to enjoy for a while.

“Now then, it is time you showed your mistress true appreciation for all she’s done for you.” Rotunda teased. Cherry didn’t need any persuasion. Now that the cream was finished she had a number of moist, wet delicious tarts for them both to eat. Without needing more instruction Cherry leaned her bulk forward and pressed her lips against Rotunda’s, forcing the tarts between them as the two engaged in a mutual stuffing and smooch that felt like heaven. Chewing with locked lips Cherry continued to magically levitate more food in for her mistress to kiss and swallow against her grateful lips - she only wanted to show just how appreciative of her she was.

Cakes, fritters, tarts, sweets. Whatever she had in the room Cherry was stuffing the both of them with until their bodies could take no more. It was after a good twenty minutes of this that eventually Rotunda was the one to give her a little push backwards with a flabby hoof and blushed heavily.

“Well well, it seems your loyalty and love for your mistress is without question. I think we’ve both benefited. See?” Rotunda mused, pushing the pad display around so Cherry could read it. The blobby Rotunda now weighed ten thousand and fifteen pounds. It seemed Cherry had pushed her a little over the edge of what she required in her lust.

“Congratulations mistress. You make me proud to have such a hefty employer.” Cherry said. “The last pie from the store. Finish it?”

“With pleasure.”

Frenzied lip smacking filled the room as the mare ate one more treat, unable to resist it. She couldn’t believe she had finally hit five figures. The fruit had helped an immense deal, she couldn’t wait to keep going. She was determined to be the biggest, fattest pony on the colony and she had the staff to help her get there. There was a moment of rest at Rotunda digested and thought of her next words.

“Didn’t I say you needed to be three thousand pounds, and now you are two? Hmmm. I think next time I’ll have to treat you. How does that sound?” Rotunda asked.

Cherry blushed, in all her time with Rotunda apart from the odd banquet here and there she had never been invited to such a thing. “If that is what you’d like mistress.” she replied dutifully.

“I think you’d like it too, clearly with those shared kisses and the amount you took for yourself. I am far too concerned with my own weight - now I have hit a milestone goal it is time I gave back a little. We’ll have you pad bound in no time Cherry.” she said with a grin on her sunken fat face. “For now, prepare the next lot of meals for our next feeding session.”

“Very well mistress.” Cherry replied, shifting her hefty bulk off Rotunda and waddling out the room, the maid had meals to prepare as was her charge. She relished the idea of further eating.
