Max burst into his bedroom, hitting the top of his head against the door frame. He yelled in pain, but forced himself to ignore it. He swung open his closet and stared at himself in the mirror. "This could be a problem..." he mumbled.
He couldn't help but notice how tall he was. He'd have to crouch down to see his entire body at once. He would also have to back up halfway into his bedroom since he was too broad-shouldered to make out his massive body. Max looked at his shirt, which was close to destruction. It had become a crop-top, exposing his hair-coated abs for everyone to see. This wouldn't do, he thought to himself. He clutched onto the front of his shirt and ripped it straight off his torso. It was close to tearing apart anyway, and it's not like the old man wanted it back. He gasped at the hirsute, Herculean body he'd been gifted. Swirls of brown fur trickled all over his torso, painting his hefty, round pecs and obscuring his thick-set abs with its density. It wrapped around the sides, and grew wildly across his entire back. It had even managed to connect with his beard, so you couldn't tell where the beard ended and his chest hair began.
Max bent down to one knee so he could finally look at his face. He raised an eyebrow in surprise. He had a dense, brown beard that was littered with white hairs along his chin. He brought a hand to his forehead, which looked far larger than it used to. His hairline had receded several inches back and now sat in line with his earlobes.. His shaggy hair was no more, replaced with a short military cut that merely accentuated his baldness. That explained the cool breeze he felt on the way home, he thought. He should've known something was up then... Small wrinkles broke his smooth skin, crossing his expanded forehead and dug into the corner of his eyes. All in all, he looked a lot like his dad.
Remembering the magic band, Max pulled it out of his pocket and slapped it onto his wrist. "How old am I?" he asked, picking up on his gravellier tone. He waited a moment, then pulled it off and chucked it onto his bedside table. It unravelled and formed into the shape of a number. "Thirty-six... Wow..." He sat down on his bed in shock. He was 20 years older than he was that morning. He was only a few years younger than his dad. No wonder they looked so similar. But he was still taller and wider than his dad. Would any of his clothes even fit him? The thought that he'd be too big made him lightheaded. He was actually bigger than his own dad, what a thrill!
Max winced as he felt a sudden pressure in his bell bottoms. His enlarged bulge was twitching and wanted release. What surprised him, however, was how far down his leg the bulge appeared to extend. It almost looked like it reached his knee cap. Carefully, he tugged the jeans off of his legs and fell back onto the bed. As he sat up, he gaped at the monstrous log that bobbed between his legs. It was massive! He knew he was well-endowed after his first age-up when his cock had slipped out from his shorts, but this was ridiculous! Without any measuring equipment around, Max had to use his hands instead. He gripped his dick at the base, amazed that he couldn't even wrap his entire fist around its girth. Then he gripped it above his lower fist, then again, and again. His cock was almost four fistfuls in length. He laughed in disbelief, surely that had to be a record of some kind?
He laid back on the bed, holding his cock up straight. He couldn't even touch the tip without sitting up. Then he let go and it smacked against his torso with a dull thud. His cock head twitched as it rubbed between the saddle of his mountainous, hairy pecs. Max groaned in annoyance and arousal. He couldn't go anywhere with an erection like this. How would he even go about getting some relief? It was far too big to masturbate with. As he stared at the pink head that sat so close to his face, he had an idea.
Max pulled himself up to his headboard and positioned himself. Leaning slightly forwards, he licked the tip of his cock with hardly any effort. He felt a tingle shiver down his spine, and pre-cum dripped onto his tongue. He licked his lips, then leaned forward a little more, just about managed to get its girth into his mouth. He kept bending down, feeling his own cock slide further and further back. He drooled in pleasure as more pre-cum coated the back of his throat. He began to bob his head back and forth, the head slamming into his larynx, his jaw aching from his mighty girth. His moans of ecstasy were muffled. As he sucked the top half of his cock, he jerked his hands up and down the remaining length of it. The feeling of masturbation mixed with auto-fellatio pushed him well over the edge. Before he knew it, he felt his cock twitch in his hands, followed a second later by his hot, salty cum gushing down his windpipe. His body spasmed from the pleasure, and he slipped his head back. His cock escaped his jaws and continued to spew more spunk all over him. It soaked his brawny torso, it drenched his thick beard, and it splattered onto his balding crown.
He laid on the bed, gasping for breath. It was the most intense orgasm he'd had in his life. It took more than a few minutes to recompose himself and attempt to sit up. His fat tool laid limp on his chest, not much smaller than it had been when it was erect. Trust him to be a shower instead of a grower. He clamoured off his bed and cringed. There was so much cum seeping into his bed sheets. Not to mention currently dripping off his naked body. He'd have to shower and change his bed before he could find some clothes.
