After many long hours at the park playing ball, you waved off the other players you'd become friends with during the day. You even recognized some of them from way back in primary school. They was a strange, special bond restored though mucking about with a ball. It didn't matter if you were a guy, gal or whoever!
Getting home it was almost dark, and you were hungrier than ever. No doubt because of your sudden 'growth-spirt' and an afternoon of physical activity. You rummaged though the fridge, chomping down on a mixture of leftovers, steamed rice and a serving of toast. It satisfied you a little, but you didn't exactly feel full.
Shrugging it off, you went into the bathroom for a shower. As you undressed, you briefly stopped to admire you expression. You were sunburnt from your day out, but more notably, you had grown in musculature. You arms were notably thicker, and your thighs had to be twice their size with noticeable definition. Your pecs had grown larger too, and you could see you had a six-pack coming in nicely. This jacket seemed to do wonders, and you were both scared and exited by its possibilities. As you showered, washing your changing body, a sudden warming buzz danced across your flesh. At first you though it was the warm shower-water running down your body but then this sensation began to strengthen and gnaw at your urges. You stepped out of the shower once you had washed yourself, your dick mildly erect. You ruffled your hair, thinking this over but shrugged it off.
You went to bed later that night.

You woke up early that morning and put on some running shorts, a singlet and your new jacket. You checked the time and noticed you were gonna be late to the Team Meetup. You got out and started into a jog towards the Local Track. You felt comfortable at this pace, your heart starting to race with not exertion , but excitement.
You felt alive!
Soon you were sprinting down your street, across the road and though your local park. In quick time, you made it to the Track sweety, got and panting but on time.
Diego was also there, as Team Captain. He smiled, noticing you were wearing the Jacket.
Good, He thought to himself.
"Don't tire yourself out just yet Jaden!" He said, grinning ear to ear.
"Sorry, I-I uh really wanted to join in today" You said though heavy pants.
Diego laughed, giving you a playful punch on the arm.

You had taken off your jacket towards the end of the training session. You were tired, sweety and aching for a rest, but despite all that you felt invigored with and underlining power and energy. Diego stood to the side, his swarthy completion seemed to glow under the morning sun, and he had been smiling and grinning at your every achievement today. You stood at the ready at the start time, ready for your official timing.
He blew his whistle and you launched off the track. You burned with energy as you ran, your flesh tingling with life, strength and an overwhelming vigor. You powered so far down the tracks that you shot past the finish line and stumbled ungracefully to the ground. Diego ran over to you looking prouder than ever.
"That was phenomenal dude!" He exclaimed.
"Thanks! That felt phenomenal!" You replied.
Diego helped you up on your feet and the two of you exchanged a checky grin. For a moment you recalled your dream, that you and Diego stood here naked and alone out on the tracks and watched as a jungle grew around you.
You could have sworn he could sense this, and he suddenly laughed and patted you on the back.
"Hey, do you wanna hang out after training?" He said.
