Hector gasped at the feeling that was spreading throughout his body. It was different than what he felt when he got younger, as his body was drastically changing.
"Oh! I think... It's working!" Hector cried out. It really was working! Hector was bulking up as he quickly aged back to his original age. The three other men watched as Hector's shoulders broadened, quickly making the loose-fitting stringer he was wearing fit him perfectly now. Billy was observing how Hector's pecs were inflating and now peaking out of the sides of the stringer. Meanwhile, Luis was focusing more on Hector's back as now it was looking quite impressive, especially compared to when Hector was skinny as a rail.
"Looking good, Hector!" Daniel complemented. Hector had to agree, he was looking good, but he didn't know where he should be focusing his attention on. He decided to focus on his arms and began flexing and relaxing them. Hector was in awe as every time he flexed them, they looked a little bigger than last time. He could only wonder how big they were going to get.
Hector then felt his core tightening and strengthening. He could actually feel six sets of abs form on his stomach. He couldn't believe he had abs now. No wait, Hector suddenly felt another two sets of abs forming on his stomach. An eight-pack! He had an eight-pack now! He didn't think that was possible for him to achieve, but he had it now, and he couldn't be happier.
Hector's lower body wasn't left out of the rate his quads and thighs were growing, which quickly made Hector's loose-fitting shorts quite snug. His caves followed suit, forming that diamond look so many bodybuilders worked to achieve. The shop owner was a bit embarrassed when he felt his glutes grow, though. He wasn't expecting them to be so big, but either way, his body transformation was complete, and now he was a Hector that spent ten years working out.
Mirror, he needed to see what he looked like in the mirror! Hector wasted no time and headed straight to the mirror in the room and liked what he saw in it. He looked good; no, he looked better than good. He looked hot! Not caring what the other men in the room thought, Hector began to flex. He needed to see how big his muscles were now, he needed to feel how strong he was, and he didn't care that his nephew was snickering at him.
"Hehe, you seem to be enjoying yourself, uncle." Luis patted his uncle on the shoulder, impressed by how solid he felt now.
"I am, I feel strong, and I'm so full of energy!" Hector smiled at the two muscular hunks in the mirror, but then he realized something. Unlike Luis, who could just return to his younger age, Hector was stuck like this. "Hey, Luis. What am I going to do when customers see me; or your father?"
"Oh, don't worry about that," Luis smirked. It seems like he had all the answers. "Just wear baggy clothes while you're working. As for dad, well, he's welcome to use the cube to buff up if he wants to." After all, Luis' experiment was a huge success. All that was left to do was figure out what to do next.
