5 minutes had passed and Derrick was still slouched in front of the mirror, watching as his body physically grew older with each passing second. At a guess, he thought he was probably in his mid thirties by now and showed no signs of his rapid ageing stopping or even slowing. His thick, dense body hair had halted its spread, leaving very little bare skin as it wildly fluffed and swirled around every nook and cranny across his body. Meanwhile, his previously slim and toned physique was getting ever beefier. His sculpted abs were but a memory as his waist thickened and had begun to convex into an undefined, solid slab. His furry pecs had even grown larger and thicker, jutting out from his chest as they attempted to outgrow his stomach. His arms and legs weren't left behind in the growth as they took on sizes he could only have dreamed of as a teenager. Surprisingly, his cock was still almost painfully erect after all this time. Derrick could almost laugh, it had to be an aftereffect of the steam as he personally found the whole experience traumatic instead of arousing.
Derrick stared at his face, counting the pinpricks of white hair that gradually begun to replace the lower half of his dark beard, and at the temples of his receding hair. He traced a finger across the fine lines that were etched across his enlarged forehead and at the corners of his tired eyes, ruining his previously perfect skin. Every now and then, he would brush a hand through his thinning hair, clumps of which stuck to his sweaty palm and advanced his receding hairline ever further. It had reached an upsetting NW4 on the Norwood scale as his M shaped hairline swept far back behind his ears, while a thin strip of hair stubbornly sat in the middle. His bald spot was rapidly expanding at the back of his head.
Eventually, Derrick snarled and slammed a fist into the mirror, fighting back tears as he retreated back to the bench and collapsed onto it. How much longer was this stupid thing going to take? If he didn't get out soon, he was going to be even older than his parents. He groaned as his stomach twisted at the unpleasant thought. He threw his fists into the air in defeat, then landed them back into his lap, hitting his cock in the process. Derrick sat up slightly, and looked to his crotch. His cock was rock solid and stood proudly upwards, unconsciously twitching as it bounced off his stomach. He grasped it with a meaty hand and felt a shiver down his back. It had definitely grown quite a bit from when he was a teenager. Almost long enough to wrap both his fists around its shaft, and enough girth that his fingers barely touched when he held it in his grasp. Derrick slowly slid his hand up and down its length, pondering what to do. It was a incredibly sleazy thing to do, masturbating in a spa sauna. What if Hebe came back and caught him jacking off? She might throw him out and then he'll never get his youth back. And yet his dick didn't seem to show any signs of getting soft, in fact it hadn't been flaccid since he found himself in this mess. Maybe just one quick session was enough. At the rate he was ageing, he probably might not get a chance to masturbate again without needing to pop a pill beforehand. Derrick grunted at his decision and quickened the pace, savouring the feeling of his foreskin sliding up and down the bulbous mushroom head of his impressive dick. At least there was something good to come out of this experience.
At first, Derrick turned his mind and filthy thoughts to Hebe. Mentally undressing her skimpy, petite body. But he wasn't feeling it for some reason. Something about jacking it to a teenager while he was probably double her age now didn't feel right. It made him feel gross. So he tried to imagine her older, she said she was usually older right? Probably much closer to his age now. A smoking hot MILF with a curvy figure and seductive stare. But this didn't get him in the mood either. Nor did his usual wank bank of beautiful celebs and porn stars. No matter who he thought of, his mind kept drifting back to his own body. His beefy muscles, and plentiful body hair. It confused him, he'd never been attracted to men before now. He admired and respected them sure, especially those who looked much like he currently did. Like his old Geography teacher. He was so cool with his huge, thick body that looked ready to burst out of his clothes. The grizzled beard and tufts of hair that stuck out from his collar. Derrick used to be mesmerised by the man, wishing that he could look like him. But thinking back, maybe there was more to it than that...?
Screw it, Derrick didn't care anymore. He just wanted to feel something good for once. And if fantasising about bear-like men was turning him on, he was going to roll with it. With his free hand, Derrick slowly dragged it up from his bouncing balls and up to his belly, feeling the dense hairs trickle through the spaces in his fingers. He grunted as he felt how much bigger his gut had grown since he'd sat down, how much larger it was overall since he entered the sauna. He was used to feeling the grooves of his smooth abdominal muscles, and what he felt now was more like an over-inflated, furry balloon. It felt somewhat soft, but had a good grip and stood solid like a rock. He gave his stomach a slight slap and cracked a smile at its subtle jiggle. It felt nice to have a gut, real nice. Especially one as strong and tough as this. Maybe he should consider changing his gym routine to gain something similar if he regained his teenhood again... When. When he regained it.
Grunting and moaning as he continued to masturbate, he moved his hand higher, following the roundness of his hefty belly up to his meaty pecs. They were positively hairy, a large mass of dark fur gathered between his cleavage and spread outwards in sexy swirls. He gripped his free hand onto one of the huge globes and gave it a squeeze. It felt much like his gut; mostly taut with a bit of give. He never had much shape to his chest beforehand, so gaining such hefty, huge slabs of beef to adorn his chest was a dream come true. He dragged his hand across the matted carpet of hair, smirking as it tugged and stuck to his sweaty palm, and located his nipples nestled within. They were swollen, and pointed downwards from how large his pecs had become. He also found, with a slight gasp, that they were sensitive to the touch. As he fondled a tingling nipple, he found that he could almost tolerate his body. He was a goddamned brawny bear of a man, that was something to be proud of.
Derrick finally pulled his hands away from his nipples and brought it up to his face, dragging it across his bushy beard. It covered his entire lower face, growing high on his cheeks and dangerously close to his eyes. He dug his hand into the intense facial hair, trying to feel the shape of his jawline. It was as rectangular as the rest of his family, aside from the soft second chin he appeared to have gained. At least his beard was big enough to hide that... Ignoring that new development, Derrick delicately traced his fingers across his weathered skin, feeling it slightly pull and sag with his movement. It was different from his previously taut features. It felt weird, as weird as the deep lines that crossed his forehead. With this thought, he eventually moved his hand up towards his scalp, his gut tightening as his fingers just went back, and back, and back until he finally felt a band of thin, fragile hair delicately resting far on top of his head. He stroked his fingers across the band, there wasn't much left. It was surrounded by massive expanses of recently exposed skin, one of the only parts of his body not covered with dark hair. He felt its general smoothness and the boundaries at the sides of his head where lustrous hair still remained in a horseshoe shape around the outside of his head. Finally he rested the palm of his hand on the very top of his scalp. With several small wipes, the last few stubborn hairs fell away and Derrick had a complete NW7. But instead of disappointment, Derrick felt relief. It was over, he was actually bald. And it felt alright? His fingers danced across the top of his head, a calm smile breaking through his beard. It felt good to be bald. But how did he look without his beautiful hair?
Still tugging on his cock, his hand rhythmically slapping against the side of his belly, Derrick pushed himself off the bench and crept towards the mirror. He almost didn't want to see how he looked now, yet his curiosity had overtaken him. He stood to the side of the mirror, closed his eyes, then stepped in front of it. Slowly, he opened his eyes and stared at the man before him. Derrick gasped, then began to spasm. He moaned loudly as he orgasmed, hot ropy streaks of cum burst from his cock and splattered across the mirror, leaving him resting up against the wall, panting heavily. Slowly, Derrick regained his posture and looked back into the mirror. Before him was a large, formidable man. He had a swollen ball belly that seemed to defy gravity as it stuck out before him, far enough that he could no longer see his feet, nor his soft, dripping cock over its sheer size. Two thick, meaty pecs coated with salt and pepper hairs adorned his chest. The beefy slabs had lost the battle of size with his waist, instead drooping down and resting on top of the belly. His beard had grown long and wild, the silvery tip tickling his chest hair bellow his collarbone, and was mainly streaked with white hairs. His once boyish looks had been overtaken by an intensely rugged look. His weathered, craggy skin was adorned with wrinkles, creases, and bags under his eyes. Up top, he was completely bald save for the thin horseshoe of salt and pepper hairs that wrapped around the sides of his head. Derrick stared at the man he had become, almost certainly older than his parents by now, with curiosity instead of fear. He was no longer frightened of the burly bear he had become. He actually loved how he looked. And, with a creeping sense of horror, he realised he wanted more.
