"You're on!" you tell your muscle-bound little brother.
You and Alex head down the beach toward the volleyball players. There are eight of them, four girls and four guys, and they look to be around your age. They're all deeply tanned, so you assume they come out here a lot. The girls are wearing bikinis that leave little to the imagination, and do they ever look good in them! All four are attractive, trim and well-endowed in the chest area. The guys have only got swimsuits on and it's clear they must work out a lot. Their bronzed physiques are even better than yours-- but not nearly as good as Alex's.
"Yo!" Alex shouts at the group. "You got room for a couple more players?"
You're a bit surprised at the confidence and assertiveness in Alex's voice as he addresses these older teens. What has happened to your shy and quiet younger sibling? Must've been replaced by this new and improved version, you guess.
The group looks you both over, though their gazes linger appreciably longer on Alex. You try not to let that bother you. After all, Alex is built like a freaking tank now; it's only natural that he'll draw attention, especially considering he's so young.
"Hey, I know you!" says a red-headed girl, pointing at your brother. "You're that kid who tested out the Gilgamesh formula, right? You've got to be!"
"That's me," Alex admits, flashing her a smile. "And you can see how well it worked," he continues cockily, hitting a most impressive double bicep flex. Instantly the teens congregate around Alex, asking him excited questions, urging him to flex some more for them, and two of the girls even asking if they could feel his muscles.
Alex handles the attention as if he was already used to being a celebrity. He answers their questions, goes through a variety of poses which show off just how spectacular his body is, and lets both the redhead and one of the blondes feel his rock-hard, eighteen inch upper arms, which are certainly the biggest on the beach.
Finally your patience gives out.
"So are we going to play volleyball or what?" you ask irritiably.
"My bro's right," Alex agrees. "Let's get a game going!"
Naturally both sides want Alex for their team. He settles the argument by opting for the cute redhead's side. All of the players take their positions and the game begins.
It quickly becomes a frustrating experience from your perspective. You're justifiably proud of your athletic ability, but you've never really had much of a chance to play volleyball before. You're still getting the hang of it, while everyone else is an experienced player. Everyone except your brother, of course, but it turns out he doesn't need experience.
From the very start Alex completely dominates the match. You thought his short height would be a big disadvantage for him, but his sculpted, muscular legs are so strong he's able to jump four feet vertically, negating that handicap. And whenever he hits the ball, it reacts like it's been shot out of a cannon.
Unlike you, Alex has never been an athlete, so you're flabbergasted by the amazing speed and coordination he displays throughout the game. Apparently it wasn't only his muscles and strength which got a boost; from what you're seeing it looks like he's grown physically superior across the board, in every respect far above what a twelve year-old should be.
Soon the score is 9-1 in favor of Alex's team. He has personally scored seven of those points, and your team's one point only came about because Kim, the redhead, got in Alex's way when he was trying to return a shot. Even though he knocked her sprawling, she apologizes profusey to him for that! In fact all of the teens on the other side of the net are treating star player Alex as if he was the team captain, gladly accepting his authority in spite of the fact that he's five years younger than they are. It makes your insides twist a bit to see how much respect and admiration they're giving your Herculean kid brother.
Shoving that to one side, you focus on the game. Melanie, the auburn haired girl on your side, is serving. She hits the ball over the net, and the next instant Alex is there, spiking the ball viciously downward. You try to deflect it, but it's coming at you so fast and with so much force that it smashes you directly in the face. Everything goes black.
