His New Jacket (Patreon)

Ben had been somewhat confused when his uncle gifted him with a leather jacket for two main reasons - one, he wasn't the type to wear leather jackets at all, and two, his uncle didn't look a thing like he remembered. Sure, it had been a few years but he'd gained a considerable amount of mass and proudly sported a full beard when previously he'd been totally clean-shaven. When Ben asked what had prompted such changes, Uncle Fred let out a booming laugh and answered cryptically, "Let's call it a second puberty, eh?"

The Uncle Fred that Ben remembered had always been a little quirky and that hadn't changed but it was a difficulty adjusting to this changed exterior. His father assured him that the differences were only because his uncle was putting more time in at the gym and had switched to a healthier diet full of nutrients but Ben was dubious. There had to be some sort of chemical reason for his wild physical changes but he was blind to see that the answer was held in his very hands. 

Growing up had been a somewhat turbulent experience for Ben and his uncle had always been the person he had confided in until he moved to a city on the west coast, far away from their small east coast settlement. Fred had always been so patient, listening to stories about evading bullies and even receiving verbal abuse from teachers, particularly the gym coach who thought that every bit of food Ben took was a waste of good meat. The teen opened himself up to my uncle in a way that he never could with his own father and his uncle was always content to just sit and listen. It was clear that he wanted to intervene on Ben's behalf but the younger man made him promise to keep his secret. All he had to do was survive high school and how hard could that be?

It had been two years since Fred had moved across the country when he returned with the gift for Ben and he was mortified to discover that he no longer felt the closeness with his uncle that he had throughout his younger years. Ben was a senior now, just days away from graduation, and while his recent days had still been full of torment and ridicule, he could see the finish line and was charging full steam ahead. He had a scholarship to the college of his choice and the future promised to be much brighter than the past. The only thing that still troubled him was his uncle's unexpected changes.

Ben waited until he was entirely alone to finally try on the jacket he had been gifted by his uncle, with a twinkle in the older man's eye and a smirk decorating his lips. The inside lining was soft against Ben's skin but there was no denying that the garment was simply too large for him, hanging off of his slender shoulders and dwarfing his lean torso. He felt like a kid wearing his dad's - or uncle's - clothes and after a moment of inspecting himself in front of a mirror, he attempted to shrug the jacket off. As he moved to do so though, a surge of pain shot through his gut and caused him to double over and let out a grunt of discomfort.

Clutching at his stomach, the young man closed his eyes for a moment and inhaled sharply.  What had come over him so suddenly to cause such a violent reaction? Reaching out with one arm he steadied himself against the chest of drawers and tried to steady his breathing. His whole body felt warm and even itchy in places, particularly across his chest, face and legs. Was he having some sort of allergic reaction to the material of the jacket? It would explain his body's sudden violent reaction and was all the more reason to get it off of him. Every time Ben even attempted to grab at the leather though he found himself doubling over once more from a fresh wave of pain.

While Ben was experiencing a renewal of his discomfort, his body was responding to the unique qualities of the leather jacket. Just like his uncle before him his muscle mass was rapidly increasing, pushing the formerly loose jacket to its limits around his expanded mass. His jeans were stretched out around thick quads and firm calves. The itching he felt was a result of the hair sprouting across his jawline and around his mouth, forming a thick black beard the likes of which Ben had never even anticipated ever being able to grow.

The pants and groans became much lower in pitch as his Adam's apple pushed out further and his body began to accelerate, showing a rapid advancement in years until he bore the appearance of a man in his late thirties as opposed to the eighteen year old he had been before pulling that fateful jacket on. The pain he had been experiencing soon turned to pleasure and the tenting of Ben's already tight jeans stood as a monument for the arousal he now experienced as a result of his transformation.

Moving a large hand down to grope at his obscene bulge, Ben let out a long moan and cherished the delightful sensation that had overtaken his whole body. His shaft felt so much bigger and yet even more sensitive - it only took a few gentle strokes and he had blown his load resulting in a wet patch at the front of his jeans and sealing his transformation into a burly older hunk. His mind slowly began to settle down from its impossible high and he let out a gruff chuckle as he realised what had happened to him in the previous few minutes. 

Stepping back in front of the mirror Ben admired his new reflection and most of all just how well the leather jacket now fit around his broad frame, almost as if it was made just for him. Suddenly he could understand - and respect - Uncle Fred's changes a whole lot more and was sure that one day he too would pass on the jacket to somebody else in need.
