Well, Aaron decided, why not get some quick relaxation in on the pool chairs? He noted that the chairs looked quite comfortable, and he could always jump into the pool later or go back and do some investigation. Right now he just felt like enjoying the surprisingly warm air out here on his body. He had little idea what truly went on out here, or the effects this simple action would have on him. He just cared for getting in what should've been some easy enjoyment.
Crossing his legs slightly as he sat, Aaron put his hands up behind his neck and enjoyed, subtly flexing his arms and core as he did so, almost hoping some girl also into urban exploration saw him out here like this. Then he could hopefully enjoy her company if she was up for carnally sharing his time.
He started to look at the twilit time, between sunny evening and night, as his body outside his perception began to change. His arms bulked and developed further, his pecs and abs further packing on lean muscle mass, glutes and legs developing further as he pushed beyond the limits of a high school going, eighteen year old swimmer. Now he began to resemble a tight bodied 21 year old swimmer starting his college career, and, as he turned and stretched on the chair, he toned up a bit more as his body readied itself for Olympic level exertion and training.
Aaron yawned and pushed his hips up, something was making them sink further down, and he adjusted himself, not noticing that his glutes had developed further - 3 years after that, at 24, evidently he left that level of swimming behind, lifting more just for size and looks than anything else. And in reflection of this, his body put on incredible size, pecs bulging out and making huge, boulder-like impressions in any shirt he might wear.
His shoulders swelled out to match, with his arms likewise picking up size and strength. He itched at his arm, still unaware, as a ring of arrows tattoo etched itself into place around his arm. He chuckled, not even noticing the deeper tone he was taking, "I feel like such a stud, streaking out here like this. Damn I have a nice body..."
Even as he said this he kept aging, to 27 this time. At 27 he if anything muscled up further as he started training for a sponsorship with some sort of athletic company or modeling circuit. He was lifting now to look good...for a living. Of course being nothing happened to Aaron's mind, he was unaware of these increasingly drastic differences in his life. His playboy life style became more pronounced - he got into fights with his on again off again girlfriend about his ways in the bedroom, and allegations he slept around with both the male and female locals at the gym.
And this was just the latest of his girlfriends.
As Aaron started to snooze a little his musculature noticeably bulked up as he headed into his thirties, his abs pushing out slightly in advance of a slight gut from a bulk gone a bit too far, but the rest of his muscles were in stellar condition and if anything became even more impressive looking. His arms flexed at 20 inches easy with his masculine, cragged hands behind his head. His pecs were a display of sheer strength and size, and his back and shoulders made the chair slightly awkward with their combined size and strength.
Aaron started to stir a little and pawed at his groin, still not noticing what had happened to him. He wondered if it'd be okay to whack off here. What if his friends saw---? Aw, who gave a shit. Chances were they were elsewhere. And he was feeling really good today for some reason. His grin took on a more perverted edge as he eyed his cock. Was it always that big? Was he always this well endowed? Yeah, duh, he decided.
