Well it's  Grendel's birthday today so I decided to write a little story about them securing the perfect birthday cake! (which apparently happens to be a well-stuffed hyena). Includes a fat rat eating an even fatter yeen while he gets pumped full of cream :3

Grendel decides to indulge on his birthday by turning Raf into a very special "cake"...

Grendel's Grump Cake
By IndigoRho

Grendel could hardly contain his excitement as he waddled along the lamp-lit sidewalk, heading towards one of the best pastry shops in town: the Lucky Yeen Bakery. The large rat was celebrating his birthday, so he'd decided to treat himself to an extra special cake, one he knew he'd fondly remember forever. His stomach was already growling in anticipation, and he gave his doughy middle a gentle pat to calm it down. Once he finally reached the bakery's entrance he stopped to take a deep breath, quickly adjusting his red jacket and black shirt, and tried his best to put on a grin that was more cheerful and devious as he walked through the front doors.

Just as he'd hoped, the only employee this late at night was an obese hyena even fatter than him. Grendel had frequented the bakery often enough to know the hyena's name was Raf, that he never seemed to smile, and—most importantly—that he looked absolutely delicious; he'd make the perfect birthday cake after some simple preparations had been completed. For the moment, though, Grendel needed to do his best to not ogle the employee like he was his next meal. He gave Raf a cheerful hello that was answered back with pure apathy, fairly expected. Rather than approach the counter Grendel made his way to a set of tanks and hoses on the far wall, the bakery's famous donut-filling station.

Patrons could simply grab a donut from the nearby bin, stick a nozzle in it, and fill it however they wanted. Chocolate, cream, and jelly were the most popular, and Grendel knew they had the largest capacity tanks as well. However, he first grabbed one of the hoses for seasonal filling, pretending to fiddle with it to no avail before turning towards Raf.

“Uh, something seems to be wrong with the nozzle, could you check it out for me?” Grendel asked innocently.

With a sigh Raf stomped over, his massive belly jiggling with every step and prompting Grendel to unconsciously lick his lips. Fortunately the hyena didn't notice. As soon as Raf took the nozzle test it out, Grendel stealthily grabbed the three main ones, creeping up behind his prey. Of course the original nozzle worked on the first try for Raf, and he rolled his eyes at the customer's apparent inability to operate such an easy thing. “Got it working, need any—mmmphh!”

Raf was abruptly silenced as three hoses were shoved right into his open mouth mid-sentence, the hyena instinctively gulping them down once they brushed up against the back of his throat. He barely had time to register what was happening before Grendel roughly spun him around, the trio of hoses wrapping around his blubbery body and pinning his arms to his sides. When he was properly bound he found himself facing Grendel, who stared at him with sinister glee.

“There's no better way to celebrate your birthday than with a cake in the shape of an overstuffed yeen,” Grendel said, quickly turning the three hoses on full blast.

Raf grimaced as he felt a torrent of chocolate, cream, and jelly begin flooding into his stomach. He desperately tried to break free of his bonds but the rat now had a solid grip on him as well, his maw opening wide. The unfortunate hyena barely managed a muffled cry before his whole world went dark, Grendel swallowing most of his head in a single go; a second finished the job. Grendel snickered as his jaws stretched to take in Raf's shoulders, his prey's struggles only enhancing the experience and making him even eager to scarf him down. He could feel Raf's gut steadily swelling from the filling, straining the buttons of his dress shirt and causing seams to faintly creak, not that Raf would be needing clothing soon.

Grendel delighted in how wonderfully soft his meal was, even while clothed. Every bit of the hyena seemed at least a little squishy. The rat's chest was bulging from his descending, squirming prey, a strong gulp forcing Raf's head into his stomach. A chorus of suppressed curses ensued once Raf had room to shout, and they were music to Grendel's ears. He bent down somewhat as Raf's ballooning belly began to enter his maw—his own sagging and bouncing about as it filled—moaning as he felt his jaws stretched wider even at rest. Consuming the hyena's immense middle took effort, but Grendel enjoyed every second of it, already greatly satisfied with the decision to stuff Raf while eating him. The hardest part was still ahead, though.

As the hyena's savory gut finally vanished past Grendel's lips the rat shifted his stance to brace himself better. With a muffled grunt he dug his paws into Raf's hips and lifted with all his might, his meal's footpaws just barely leaving the ground. Raf immediately began flailing more once he realized he was airborne, knowing his slim chances of escape would be completely dashed if gravity was used against him. Unfortunately being pressed against a fleshy stomach wall in the dark while his gut grew painfully taut made coordinating his actions practically impossible. Swallow after swallow Grendel's belly bulged outward, pushing out from under his shirt wobbling for the whole world to see. He was in the home stretch now, his success all but guaranteed.

The voracious rat gulped down Raf's butt, then his thighs. Raf's weakly kicking legs hung from Grendel's mouth, a wide grin visible. As Raf gradually slipped away Grendel cradled his blimping middle, running his paws all across the lumpy surface, pleased by every shift and wiggle. With care he lowered himself to the ground, removing the load off his legs and using his massive belly like a beanbag chair, one that would only be getting larger from then on out. Inevitably Raf's twitching paws slipped behind his jaws, which sealed shut around them and the hoses still sticking out. A delightfully long gulp sent the last of his prey into his stomach.

Still, Grendel continued to grow. The three tanks had only emptied half-way, and Grendel intended his “cake” to be filled to the very brim. He could feel Raf's struggles becoming weaker and more haphazard as he ran low of space within the stomach, stuffed to the point of utter immobility. Bulges along Grendel's belly were slowly being smoothed out as Raf grew rounder, the hyena's own blubbery gut working to conceal his presence. Grendel's bean bag chair swelled into an outright bed, the rat gleefully patting and prodding the parts of his belly he could still reach as he rose higher and higher. Raf was beginning to creak within, his stretched thin as he was turned into an overindulgent dessert, but the tanks ran dry well before he would've burst.

Finally satisfied, Grendel gritted his teeth until the hoses were severed, swallowing the torn ends as well; their bland taste was a small price to pay for the meal he'd gotten thanks to them. His enormous gray middle was gently wobbling back and forth from his cake's useless struggles, Grendel beyond content. He wouldn't have minded feeling Raf inflate a little more while inside him, but in the end he couldn't argue with the results. Though he'd be stuck in the bakery for a whole day at least while he digested the cream-filled hyena, Grendel had no regrets. The rat would just enjoy the extended rest and then happily waddle out the front doors tomorrow...if he still fit through them. Grendel laughed and sighed, letting his mind wander as he imagined how much permanently rounder he was about to get, and who would have the honor of being his cake next year...
