It was a bright and sunny day at the Park, the heat of the sun beating down on the various workers as they went about their daily chores for the park. One of these workers was a blue jay by the name of Mordecai, and currently he was raking up leaves that had fallen from the many trees. He was in his typical attire of only wearing a tight set of jeans, his tone upper half on display. He couldn't be called muscular per se, but he did have some muscle tone.
 
He wiped the sweat from his brow, sighing as he stopped for just a moment to rest. He'd been working since practically sunrise, unusually motivated given his typical routine of slacking and goofing off with his best friend Rigby. It was just passing 1 o'clock in the afternoon, and Mordecai began to feel weak. His stomach rumbled loudly, and he realized that he hadn't eaten anything the entire day, even for breakfast.
 
The snack bar that he usually ate at was pretty far from his current location, and he wasn't entirely sure he could make it over. But the growling of his stomach was more powerful than he'd ever felt before, so he knew that he had to find something quickly. He began looking around and noticed a large jackal taking a jog through the park. When he saw that muscular frame, black fur glistening with sweat, his stomach growled even louder.
 
He couldn't help but lick his beak as the jackal took a seat on a nearby bench, not seeming to notice Mordecai behind him. The bluejay had no idea what was taking over him, but he moved over to the bench quickly. He wrapped his arms around the jackal's chest and opened his beak, swallowing his head. The jackal began to thrash about, unsure of who was attempting to swallow him.
 
Mordecai loved the musky taste of the jackal, moaning a bit around his head as he swallowed hard, pulling the head of his meal into his throat as those broad shoulders stretched out his mouth further than anything had ever before. He reached down to tear off all of the jackal's clothes, taking notice of the tight snatch between his legs where a dick should have been. If he weren't so hungry they could have had fun, but he couldn't ignore his stomach.
 
Another swallow pulled those beefy pecs into his maw, the avian drooling around his massive meal as the jackal continued his pointless resistance. A couple more swallows and Mordecai had the jackal's waist in his maw. He tilted his head back and let those legs slide down smoothly, closing his beak and giving one final gulp to send the jackal down. He felt his stomach bulge out further than ever before, the jackal squirming violently inside. Mordecai just moaned, rubbing over his huge gut.
 
"Sorry man, but I needed a meal and you just happened to be close. Don't worry, you'll give me lots of energy." He said as he then returned to his work, ignoring the squirming and yelling from his stomach. He felt strangely revitalized despite the weight of his stomach and it's occupant's fighting, getting his work done faster than usual. As he worked his stomach began to shrink down, digesting the jackal fully just as he finished his last task.
 
When the jackal was gone, Mordecai would feel his body swelling, his muscles growing larger and far more defined than before. He gasped softly as pleasure raced through his body, feeling stronger than he ever had before. He looked down and admired his new muscular form, flexing a bit to get a feel for it all.
 
"Oh geez, I didn't expect this to happen, might need to start eating hunks more. Well I know Andrew will love these changes~" He said, referencing his smaller lover as he made his way back to the house at the center of The Park to show off his gains to the feline he called his boyfriend.
