Big Boy Undies 4

 

 

Jerome was just so caught off guard when he put on his older cousin’s underwear. He was just curious about the boxer briefs and what it felt like to have them on. He’d seen briefs. He’d seen boxers, but this was something completely new. Putting them on was no doubt a violation of privacy, not that Jerome considered such things. They were close like brothers, and to his understanding brothers and sisters stole clothes all the time from each other. 

The moment he got the boxer briefs on; there was an immense heat from his crotch. His dick swelled, and then it sagged in his cousin’s underwear. A large throbbing member was attached to him like a foreign object. He didn’t have time to react as his balls had dropped lower to fill his pouch better. Freshly produced testosterone, stronger than his own, flooded his system. Jerome’s body spasmed, soaring in height, spine cracking along the way as his legs stretched. Two pecs perched themselves onto his chests, healthy and meaty, as abs formed like a stone road leading lower. His shoulder gained strength in tandem with his arms and hands increasing in size. Ink melded itself onto his skin claiming his left pec and arm. A watch and bracelet popped into existence on his arm as an earring embedded itself in his left ear. His cousin’s style had passed a version of itself onto his body. The young face matured, fat trimmed away for a strong masculine structure. Thick lips puckered into place as a mustache and goatee grew in and framed its status.

Then the growth came to an end.

Jerome, the man, stared at his hard cock stretching the material of his cousin’s underwear. He was confused to see not only that, but himself. His mind was different. The world was different. And yet he was the same person that put on his older cousin's underwear. Only now he was rocking it. He was a specimen to be gawked at, not a curious onlooker. There was something about wearing tight fabric that did little to hide the outline of a dick in need. He now knew what it felt like to have boxer briefs on. His cousins and so many other men’s sensibilities floating around in his brain, powering his body. 

Best of all, he knew the joys of taking them off.
