Luis waited until he was sure he was more alone before he commenced taking off his shirt and jeans, leaving him in a pair of tight white briefs that clung a bit to his ass - a consequence of lack of new clothes. He'd probably been wearing these since...what? Fourteen? Fifteen? It wasn't so much that he was shy in as much as he was conscious of just how much attraction he had toward her - and he wasn't keen on immediately chubbing up just from being almost naked in the same room as her. It would probably make the grown woman chuckle at him, laugh at his teen libido - and even for a gangster like Luis, that would just make him feel like running away.
Indeed, as Luis stood there, just thinking about her and him in the same room made him start to get turned on. The teen bit his lip, and turned, hoping that if there was something where she could look in, she wouldn't see that. Maybe. Maybe once he was done in there, when he was sexy and healthy and good lookin' by any metric, he could let her see him like that. He wouldn't be quite as awkward. He marched into the sauna...
And promptly coughed and hacked as he registered the sudden suffusion of hot air wafting out from the room. It was completely different from anything he'd ever done - and yet, despite the immediate unpleasant nature of walking into that wall of hot air, it wasn't wholly a negative experience. Just standing there, letting the heat wash over him for a moment, Luis smiled and breathed out, in, out, acclimating himself to the room's temperature.
Looking around in there, he found himself looking at a pretty basic set up.
An island at the middle with something at the middle that seemed to be releasing some of the heated mist, along with some vents that likewise produced some of the hot air. Located around the room were a number of wooden benches that lined the walls, the floor was made meanwhile of a sleek, ceramic substance Luis had little clue about. He wasn't exactly one of the "rock geeks" as he called them. The boy stepped inside and winced as his feet made contact with the hot floor - and he swung the door shut again behind him.
The feeling of being submerged in all this hot air by himself was a strangely stirring one. His pores began to open, and he sighed, taking a seat. Even now he could feel a sense of a hot cleanse. Even as he sweat, it was cleaning things out. Letting him feel more limber and relaxed. Initially, Luis had thought about how weird it was that people talked about the sense of relaxation of being in a sauna. That it seemed like an odd place to find relaxation - he would think that playing Street Fighter or watching some movies would be the most relaxing thing...
...But now? Now he kinda got it.
And honestly, it wasn't just relaxing - it was kinda hot in here in other ways. The heat was interacting with the heat in his crotch. It did not take very long after Luis sat down on one of the benches along the wall, specifically to the right, such that the lady couldn't see anything that, ah, went on. That is, that his cock was tight against the front of his briefs, thick and hard. Luis bit his lip, and tried to just sit there. He didn't wanna waste a load if---if he had any hope with her at all.
Sitting there in the slowly more steamy sauna room, Luis was barely conscious whatsoever of the things that went on. He shifted in his seat, not noticing that his legs were swelling, thickening, and growing longer. Giving him a bit more height. Rather than an ache as one might expect, the magic of the room made Luis' legs simply feel pleasantly tingly as he experienced his growth spurt - a feeling that progressed up his body.
When Luis' ass began to thicken and grow more muscular, forming a tight bubble butt against his seat and his increasingly stuffed briefs, he grunted outloud - hoping that she wouldn't hear that and come investigate. He was roughly 18 by this point and only growing further as he sat there, trying not to adhere to the growing voice inside him calling on him to just...get a little more hands on with himself. To, bluntly, masturbate and bust a nice thick load in here.
It was hot, and nobody was watching. Nobody was out there. Nobody could be lookin' in there. He was young and he was strong. Luis had never really felt this...this virile before in his life. His shoulders pressed against the bench and grew wider, their breadth and their size pumping up - front delt, lateral delt and rear delt all thrumming with muscle - and Luis' only acknowledgement was rolling his shoulders as he felt somewhat awkward in his position.
Him clenching his teeth was met with his jawline shifting and adjusting. His chin became stronger, getting a little cleft in it, giving him that classically handsome look. His awkward and uneven teeth shifted, growing a handsomer look. His face was turning more angular, growing from the slightly chubby and round look of boyhood to the angular and appealing features of a young man indeed.
Luis awkwardly shook his arms a bit to deal with some sudden tension in his biceps and triceps, even his forearms felt a little...weird. He couldn't have known that that was his biceps and triceps beginning to swell, muscle fibers building up from workouts he only had in the sense they were being added to his history. Even his forearms looked substantially more impressive - all the better for giving a strong handshake or throwing a strong punch.
It wasn't just his muscles that were changing though.
Even as his face grew handsomer, his hazel eyes staring from below a strong brow and framed by high cheekbones, his hair underwent a bit of a reinvention. Even as he drew his hand up and put it through his sweat-stained hair it responded. His hair grew thicker, it curled to the either side, a very good looking wave and curl visible in his locks. He was looking more and more like a Hollywood Movie's dashing rogue than the awkward adolescent wannabe he started as.
By 19 going on 20, Luis was distinctly feeling the intensity in his groin. He figured that the babe wouldn't be looking in. She probably had like---like paperwork or some shit to be doing. "Yeah...ahem, ahem, yeah..." He figured his deeper voice was the steam and the heat of the room interacting with his register. "She---she probably won't look in here. Which means..." He grinned as he looked at his cock, just about 8 inches now and almost extending down his leg to escape his briefs, "I can take care of you."
Luis pried down his briefs, not realizing as of yet just how thoroughly he had changed - his first indication however was how thick and big his cock was. His face lit up with a delighted grin as he saw his manhood looking like that. "Ohhhh baby, I am looking huuuuuge! Holy shit, holy shit! I gotta tell some of the guys from my school about this...mmf...fuuuck, my dick..." Luis actually pumped his hips in the air once or twice just to get his arousal out of his system.
He then gripped it in one hand, looking at the throbbing, oozing cock. The precum dripping down his manhood and now staining his fist. A couple droplets hitting the floor and starting to evaporate already. Luis grit his teeth...and started. He found himself moaning, actually moaning, as he thrust into his waiting, adoring hand. His pectorals swelled as he felt pride in his newly enhanced cock. He could---he could really please babes with this thing! He could wear one of those tiny briefs to the beach and he could walk around like a confident guy!
Luis actually felt attractive, good looking, handsome. And why not? With those abs and obliques carving into his midsection, defining themselves so clearly, he didn't feel like a half formed teen any more. Luis felt like a fucking man!
But as Luis thrust into his hand, his own excitement would be his undoing, as it were. He was so very into whatever was going on. So utterly excited. Eagerly pumping his hand as fast as he could go on his dick. Trying to get as much pleasure as he could in the heat of the moment. The 20 year old Luis was eminently attractive, a beautiful young Latin stud, but he had the very same degree of personal sexual prowess of his younger counterpart.
As in, none. And no capacity for measuring what he was capable of, and any ability to hold off from the pinnacle.
Luis gasped, feeling a sudden burst of pleasure flying through his body. He grunted, feeling his anus clench, his balls draw tight to his body, and his cock fucking pulsed...!! "Aww...AWWWWW FUUUUUCK MAN!! I'm gonna---gonna fuckin' cum!?" As ill prepared as he was for his muscled new body and his surge of sheer vitality, there was only ever going to be one outcome for young Luis.
As he crested that last minute, and reached the age of 21...Luis hit his orgasm. And his whole body shook as he watched his cock wave about, globules and streams of cum flying into the air, some awkwardly landing on his leg, others landing on the floor with a wet series of spurts. He laid there for a good few seconds, catching his breath, and then got up. He breathed, and managed to stuff his cock back into his briefs. Realizing as he did that it was a damn tight fucking fit.
And he could see the front of his briefs stain with some of the leftover cum not yet expelled in full.
Luis stumbled and walked out of the sauna, and into his first experiences as a 21 year old.
He saw that a mirror was left out for him to get a better look at himself. He had thought it would just be his cock that got bigger, maybe he had some slightly better looks or something, maybe his skin looked clearer...? But he was not prepared for just how damn hot he looked. Luis almost fell to his knees at the sight of himself. He had never seen a man that looked like that before in his whole goddamned life. The closest was his gay uncle Ricardo to the south of the border, and even he didn't really match the sheer fitness and muscled glory of this new Luis standing here before him.
Luis chuckled, and he threw his arms up in an awkward, amateur flex. He grinned and he preened, showing off for the mirror and anyone who was watching. He was so...so good lookin' now! They weren't kidding, those rumors about this place making you all like, hot and stuff. Luis crossed his arms over his thick, muscular chest, "Fuuuuuck, I look like, so good..." He then looked down at his groin, "I wonder if she'd want me now...?"
"I mean, I'm no awkward kid any more. I'm so buff! And I'm so tall!" He had no idea as to his new age, but he just assumed whatever happened, it left him in this wonderful state. He could hardly recognize himself. His...his gang could probably not even recognize him. A juvenile fantasy occurred to him. To make use of these angelic good looks and run off, to the big city, to make his name in the---in the like, shows 'n' shit. Maybe---maybe he could be a somebody with these abs.
As Lilianne watched him from afar, she did admit. He was something else. Honestly, maybe she could just go make Luis' day...
