“Unggh… Cadee…” the corpulent Crystal prince called out in a stuporous tone.
 
“What is it, my butter boy?” Cadence trotted up to him, levitating a local bakery’s stock worth of goodies before him. “I have the rest of your snacks just right here.”
 
“Oh… I… Urrp- I can’t finish all those ‘extras’ tonight…” Shining moaned. my stomach… uhhhhgh.”  
“GrrrooOUURP…” The complaints of his stomach told Cadence the rest of it. His taught tummy was punishing him again for his newest feat of unbridled gluttony—fueled by Cadence’s want of a Prince worthy of the Crystal empire and Shining’s own new need to be kept “topped off.” Unfortunately, the race to fill himself by the end of the day tended to lead to an over-saturation of food within him.
 
“Oh, my poor hubby!” Cadence cried with guilt spoiling her happy tone. “I knew I was pushing you too much, I’m—I’m so sorry, I wasn’t thinking about your limits again and I got–“
 
“Calm down, I’m fine.” he coaxed her, without having to raise an almost immobilized hoof. “And I think I know how to fix this too… honey, you might want to–Broourp–scuse me, step out of the way…”
 
“Uh… from what part of you?”
 
“My face, sweetheart—I’m gonna make some room… also, cover your ears.”
 
“But why-whaaa!” She yelped as Shining pushed her away with a bit of magic. As soon as she wasn’t in the kill box, He took in a deep breath as he prepared himself. He began to lift up a part of his swollen, stupendous stuffed looking belly—colored with so many stretch marks it looked like a manticore had mauled it. He strained to lift the weight of it, but the strained even more to hold back the induced belch building up within him.
 
As he managed to lift up the pride and joy of their relationship by a mere 2 feet… he dropped it. The sound of the slush sloshing inside of it made more of a sound than everything hitting the mattress he was laying on. But that was drowned out the other sound.  
It went on for six seconds. Not including that start-up phase where a burp ramps up. It… it was a wet sounding one, being a clear “buuurp” if it were to be judged as an onomatopoeia. But the expulsion was so massive, that the author refuses to bother describing the exact sound of it in text. It shook the room like an earthquake for a moment
 
After his belch ran out of fuel, Shinning was panting for air. Even the strain on burping on such a big and good blubbery boy knocked the wind out of him. But at least it wasn’t as strenuous as stretching a leg, or for the love of Luna, shifting his belly slightly.
 
“Goodness, Shiny!” Cadence cheered as she recuperated. “You.. you almost blew over all the cakes here! That was…”
 
“Impressive?” He finished for her. “Yep… even like this, I can still do a few offensive maneuvers. Those cakes look like they were about to attack my waistline.”
 
“Hmm… well, they probably want to join your kingdom there by the looks of it!” Cadence poked at one of the folds that emanated from one of the most muscular breasts she’d ever seen at one time. She didn’t mind trading that detail out for the fattest chest that she’s ever seen. “Now, what does my wobbly warrior need other than a full tummy today?”
 
“Uhhh… now that you mention it. Some belly rubs ASAP would be awesome.” Shining delightfully ordered.
 
“Hm, I’ll be sure to get onto to that now, my stuffed stallion… oh, you look so cute, all wanting to finish the leftovers from the games yesterday!” She stopped to turn back and give Shining a little boop on his snoot, squishing his fat face in even more. It was her favorite part of his new physique… just right after the belly.
 
“And you look a nice as ever, sweetheart,” he responded. With blushing cheeks of different magnitudes of size, they went in for a kiss. After that, Cadence walked over to rub her hubby’s gut into submission.
