“Yesss, right there my lovely little gut slut. I can feel the pressure riiiight URP there...”

	Princess Celestia let out another ragged belch. Her stomach had deflated a little bit since you started rubbing her belly but there was still far more food than trapped gas sloshing away in her stomach. The former princess let out a little moan as you applied a little bit of pressure onto the same spot. A moment later, another large belch rang out through the bedroom.

	“Wonderful...simply wonderful. I can't believe we've gone so long without a stallion that knows how to treat a mare of this size.” Princess Celestia cooed as you spread yourself out upon her ocean of a belly and began to massage all over. “I'm feeling much better now, Anon. Thank you so much.”

	“Anything for a sexy mare like yourself, Prin...Celestia. Do you need anything else tonight?” You asked the former princess.

	“No, Nothing else, my dear Anon. I've taken up too much of your time tonight. I think it's time I slept this off.” Princess Celestia leaned back into her wide, flabby neck rolls and began to doze off.

	You were without orders for the time being but you continued to rub and massage Celestia's massive gut. The former royal sisters were already massive when they approached you for your skills and services but this was a dream come true. You worked hard to fulfill their every desire, every greedy demand and it shows. Both princesses were immobilized by their own bodies, completely buried under literal tons of fat and blubber.

	The monthly stipend was appreciated but it wasn't about the money in the first place. You got to spend all your time with two massive, sexy mares and they were just as lewd about it as you were. Celestia loves to tease you with her gut and always shows off how much she can eat while Luna is always wobbling her ass with her magic to distract you.

	Gentle snoring broke you out of your thoughts. Celestia had finally fallen asleep thanks to your expert belly rubs. Not even the loud gurgling of her belly or the ache of her stressed stomach could raise her from such a deep slumber. A shame, since all this rubbing had gotten you horny.

	Without warning, something had grabbed you by the tail and yanked you through the air. You found yourself flying towards Luna's side of the bed with great speed. Luna's vast, fat filled face soon came into view and with it was a sly, knowing smile.

	“Good evening, Anon. I trust my gluttonous sister and her belly rubs have you nice and warmed up, correct?” Luna's eyes were filled with lust as they wandered past your face and onto your stiff erection.

	“I might be willing to satisfy a carnal urge or two at the moment. All you have to do is ask.”

	Luna giggled. “I may not be a princess anymore but I shall never ask like my weak sister. You're going to fuck me HARD tonight until I say stop.” She pushed you towards her face and gave you a big, sloppy kiss. Luna pulled you away only to pull your crotch to her face and give the tip of your cock a loving kiss as well.

	“Go, my horny helper. Fuck me until I lose my voice!” Luna once again commanded before shoving you deep into her butt crack. It was the only way you were ever going to wiggle in fast enough between Luna's massive cheeks to satisfy her. The heat of her body was overwhelming as tons of soft flab pressed around you from all sides.

	“Yesss, nice and deep. Oh, its been so long since we've indulged like this!” Luna moaned. She was being dramatic. It was only yesterday that she was eating doughnuts off your dick. It didn't matter what she said at this point. Being surrounded by all her wobbly booty was boosting your arousal. You were neck deep in her ass meat and it was the only place you wanted to be.

	Finally, Luna's magic had pushed you deep enough. Your tip was pressing against her wet pussy. Luna let out another feral moan as you slowly pushed yourself forward with all the leverage you could get. Inch by inch, you entered the obese blob of a mare and made her shudder. Her back fat and ass wobbled hard as she wiggled in delight.

	You pushed and pushed your hips forward until there was nothing left to give. Both you and Luna moaned as you plunged your entire length inside her. The sight of her immense ass wobbling from your efforts spurred you on. Slowly, your momentum began to transfer to Luna's many rolls and blubber. The pressure of her ass fat swaying against you help keep your pace.

	There was no stopping now. Her body was doing most of the work now as she swayed and wobbled. You timed your thrusts with the ripples as it helped you get as deep as possible in her needy pussy. More and more, faster and harder, faster and harder. You both needed it as your bodies drove each other to the brink.

	As badly as you wanted to spank Luna's fat ass as you came deep inside her, it was impossible. Your whole body was wedged deep in her crack. Not like she would feel it anyway with how massive of an ass she had. You kept thrusting for as long as you could to make sure Luna hit her own peak.

	Luna let out a sultry moan as she climaxed. Slowly, the rocking and jiggling of her massive body subsided. Another job well done. You relaxed as well as you could still wedged in Luna's ass crack and let her come down from her explosive peak.

	Five minutes passed, then ten. Luna still hadn't said anything. Your hooves were getting a little numb from the pressure at this point. “Uhh...Luna? You did want me to go all night, right? You okay? Still need some time?”

	Your questions were answered with a loud snort. “Luna? Luna! Hey, are you okay?”

	The snorting soon gave way to loud snoring. “Oh jeez, one and done? She really passed out on me after one time? What a lightweight....heh.”

	With your task done, it was time to relax. You try to pull your legs up and out of Luna's sexy, wobbly ass with no luck. The pressure of her cheeks were simply too great and her body was too soft and doughy to climb. Magic was the only way out and the only two unicorns powerful enough to pull you out were fast asleep.

	“Well...could be in worse spots...” You mused. You did your best to get “comfortable” and did your best to fall asleep. With any luck, one of them would wake up in the middle of the night and want a snack.
