Fred instantly dropped the clothes and sprinted for the front exit. His ass hit several racks and knocked them down, but he didn’t care at first, only deciding to care when the impacts were making him bounce left and right uncontrollably like a pinball machine.
He paused to look at the carnage behind him, seeing a line of racks knocked down like dominos all because of his expanded rear. Speaking of, his expanded rear was beginning to block his vision behind him.
That’s when the growth started. Fred felt it almost immediately: the tightness beginning to take hold again, the sensation of it all. It felt like someone was pulling out and down on his ass, trying to take it away.
Realizing that he still standing still, Fred made his way to the center aisle and started his sprint again. His bulge, which had already grown without him paying attention to it, bounced up and down like he was doing jumping jacks.
His run began to turn into a waddle with every step he took. His ass was becoming large and tight enough that his cheeks were rubbing together, causing pain if he kept them together. But as he transitioned to a waddle, his ass was becoming so large that the waddle was not helping. He could feel the force of him moving with each step jolt into his foot and make the corresponding cheek vibrate beneath the ever-tightening sweatpants.
As Fred finally made it through the sliding doors, he was relieved to find that he remembered to put his keys and wallet in the sweatpants pocket. They were practically glued to his thigh in the pocket, the strain of the growth on his rear made the pockets and everything in front of him go taut. He pulled them out as carefully as he could to prevent anything from stretching.
Fred unlocked his vehicle, which was actually a decent sized truck that his dad had gotten him for his birthday. He muttered a “thank god” as he climbed in the drivers seat and quickly slammed the door. Starting the vehicle, he was relieved to find that he could fit (not by much, but it was doable) in the seat. It took him a few tries to get his seatbelt around his wide right buttcheek, but he was able to do it.
Putting the truck into drive, he quickly pulled out of the parking lot. There were a few speed bumps on the way out. As his truck went over them, Fred felt himself physically bounce in his seat on his trunk. It was a violent shake, throwing him to and fro, back and forth. He felt like he could have hopped if it weren’t for the seatbelt.
After all the speed bumps, Fred was finally able to pull out into the main road. Moving further down, he realized that he was slowing down. Why was that? His foot wasn’t on the brake, he wasn’t going up a hill, he shouldn’t have been slowing down. Moving his foot to push the gas pedal, his foot hit open air.
Panicking, Fred flailed his foot around try to hit anything, but it couldn’t. His feet were permanently away from the pedals. Fred quickly pulled over while he still could and let gravity slow his truck down to a stop. Still flailing around, he realized that his eye level was almost at the visor near the top of the windshield. “Oh god.” He thought. He had thought that his butt stopped growing. But it clearly hadn’t.
The tightness had masked the growth, as his sweatpants were always tight. His butt had grown while he was in the seat, pushing him upwards toward the ceiling after it was unable to go wider. He realized that his cheeks were tight in the seat, pressed directly on the door and the middle part of the truck. He struggled to wedge his left hand down through between his cheek and the door, getting a massive wad of bouncy and jiggly ass cheek flesh. The pressure put on it was larger than he has ever experienced.
Finally reaching bottom, Fred found the source. It filled him with dread. His sweatpants had gotten caught in the door when he closed it, putting them in a permanent state of stretch. And with that came a permanent state of growth for his backside. Or at least, that half of it. Clearly, the other side was caught on something too. Fred flung open the door to stop the growth of his left cheek, and felt the sweatpants fabric slap back on to his rear, sending a jiggle shockwave and making the other cheek grow even tighter. Unbeknownst to Fred, his cock was straining under the tightness. Growing upward in the seat has forced it to smoosh against the steering wheel, making him even more uncomfortable, but Fred was preoccupied with his ass.
Going through the same painful process, Fred forced his hand down the other side between cheek and plastic and found that the sweatpants were stuck on the seatbelt. It took him a few tries to get it undone, but when it finally did, it flew open and Fred got out of the car as quickly as he could. He didn’t want to end up stuck in the car.
Because he relieved his left side first, Fred’s right cheek was slightly bigger than his left. He didn’t know what to do except feel them and be in awe of how large they were. They were as big as beach balls, making the pink sweatpants cry for more room. What will he do now?
