Luis gasped as he started to feel the sensations of aging coming up on him, all at once. He had been prepared for something a little more restrained, but the sudden influx of a strong, pleasant tingling feeling made Luis almost fall backward on his ass from the sensations. Luis started to grow, visibly so, right in front of Billy. "Dude!" Billy shouted as he watched Luis's shoulders quickly starting to fill out his shirt, "You gotta get your shirt off! You're getting buffer!"
Billy could just watch as Luis slightly grew taller and his face seemed to start to grow older in its look. It was actually astonishing to Billy to get to watch Luis go through this. It looked like it felt great, and made Billy feel like growing older again himself.
"S-Seriously dude? Ohh I can feel it!" Luis' t-shirt was quickly becoming less and less good for his form, and before long Luis grimaced and tore it off, tearing a few seams in it and tossing it to the side of the room. He stood there gasping for air, and yet even as he did so his abs sculpted themselves into existence. Not nearly as rippling as Billy's abs, but definitely well honed. He was going from the friend Billy only really talked to to someone he was eager to count as a friend.
Maybe it was the influence Billy had on him through the years being accounted for. Luis evidently seemed to really like working out his back, because it widened and strengthened noticeably, becoming tighter and the lats developing a really nice insertion, especially with his former stature in mind. Billy watched eagerly as Luis' formerly baggy pants filled out from his quads and calves.
"Dude, awesome pecs!" Billy smacked Luis' chest, which was filling out as well, and before long Luis stood there, a well honed, muscular teen much like Billy Brand. The process had taken Luis from merely being the kid friend to looking more like Billy's fellow jock to be. Luis almost didn't even know what to say by the time it was all finished.
"...I'm like, so freaking big..." Luis murmured and looked himself over in Billy's mirror. A flex of the arm showed Billy was about an inch bigger arms wise, but Luis' arm was slightly more toned for it. "We look so awesome, Billy! I definitely see what you meant!" Luis was not regretting his decision to go ahead like his friend said. It had been difficult to believe, but here they were, standing here like this.
"Dude, should we like workout or something? Give our bodies test drives?" Billy said with an excited look on his face.
"Yeah that sounds fun, you do have more than enough workout gear here. But---maybe we need to do something else..." Luis said, clasping his chin. He looked at Billy - now he was older, he was starting to feel funny. Working out and hanging out with Billy was good and all. But there was something that made Luis feel weird. Kinda like when he and Billy checked out high school girls.
Luis contemplated if he should go ahead and try and make a move...but there was the issue of their current age. He didn't want to do anything and have Billy refuse and then possibly leave him out of any further aging. That had felt so amazingly good. Luis decided to keep that in his back pocket.
"What do you feel like doing, man?" Billy asked, stuffing his hands in his pockets. To tell the truth Billy was looking forward to going out and doing more stuff now that they had this Cube and no parents around right now. Luis had been looking at him...weirdly, but Billy didn't mind terribly much. Luis was probably just comparing their bodies!
"Well, maybe we can go out and uhh, do something. Like go to the movies, or try and hang out with the high school girls..." Luis said looking down and contemplating how that might go. The movies sounded fun, but that other idea...
"We could make ourselves like, 21 or something and go see something R-Rated!" Billy said with a grin. That was another thing he'd been looking forward to doing. Too often his parents had told him that he was too young for those kinds of movies. He disagreed, but he couldn't well do much about it. But that was before the Cube! Now he could actually make an effort to get into those kinds of things. What to do...what to do...
