Juan considered the situation for a moment. He stood, and looked over at the locker room mirror, staring at his reflection. He was huge now, his muscles thick and powerful, looking ready to erupt from under his skin, deeply striated, covered with veins. He loved the way it looked, loved the sight of so much power under his tanned skin.
“You, you can make me this big naturally? No bad side effects? Just pro-level muscle mass?” he asked at last, looking down at Ty.
Ty nodded slowly, to confirm it.
“My gut will shrink, and I'll get my balls back?” Juan asked, following up.
Ty nodded again.
“Fuck Ty,” Juan sighed, “You remember how it was. Back when I was the class runt. Back when people called me 'Juanita' and said I was the smallest girl in the class... even though I was a guy...”
Ty nodded slowly, remembering when Juan had been the target of torment.
“But I lifted, and got bigger. And yeah, I took 'roids. No choice, way I saw it. Get bigger, or stay the runt that everybody steps on.”
“Well, that became me, later,” Ty pointed out, a sour note to his voice.
Juan turned to him. He stepped forward, and put one big hand on Ty's shoulder. “Not anymore, man. You're my buddy, and I'm sorry I left you behind. I know what it's like, down at the bottom. I guess I just worried that if I hung out with you, people would see the real me – the old me. Small, weak, nerdy.”
Ty nodded slowly. He did understand what Juan was talking about.
“But you can make me huge like this, Ty? Keep me big and strong, without the drugs?”
A smile came to Ty's face, and he concentrated. Juan felt a shiver run through him, and then his gut began to shrink, his heart slowed down to a strong, steady, healthy beat, and he had to adjust his stance, as his scrotum filled with healthy nuts once more, pressing against his huge thighs. Juan gasped as an electric current ran through him, settling the changes into place. He looked into the mirror, and his jaw dropped. His reflection was magnificent: pro level mass without a hint of roidgut. Even his acne had cleared up. He brought up both big arms and flexed, watching his biceps surge upward, thick and hard as stone. He chuckled with delight, going from one pose to the next, watching his big new body in the mirror.
Finally, Juan turned to Ty. His cock was hard again, and a light sheen of sweat was starting to form on his skin. “Ty... I can't thank you enough. This is incredible!”
Ty grinned back. “I'm just glad I could help. I didn't want you to kill yourself, you know...” Ty blushed a bit. “I don't mind seeing you big like this. It's kind of cool. You look good, this way.” Ty's blush deepened.
Juan flashed Ty a brilliant grin. “Thanks man. Thanks for helping me get to this size.” He took a step back, so that Ty could see every bit of him as he flexed his powerful body.
“Not to be greedy, Ty...” Juan said slowly, hesitantly, “I really appreciate everything, but...”
“But what?” Ty asked, when Juan hesitated. “Just spit it out...”
“But, well... I wonder what it would be like to be even bigger? Even freakier? My muscles even bigger and stronger? My whole body, bigger and more powerful?”
Ty was surprised. Juan was so big already! But seeing the expression on his old friend's face melted any resistance he might have had. He smiled at the big young man. “Well, maybe a bit bigger...” Ty concentrated, and Juan felt that familiar tingle return, as his body began to change...
“Oh yes...” Juan hissed, a blissful grin spreading across his face. His muscles trembled, then started to grow, swelling to even greater size, pushing out thick veins, filling the 18 year old's body with ever greater power. “Oh fuck YES!” he roared, raising his arms, flexing his swelling biceps, eyes wide and shining with excitement.
“KEEP GOING TY!” Juan howled, his deep voice crackling with excitement, “MAKE ME HUGE!!!”
Ty was taken aback, but complied, watching his old friend swell, larger and larger. Ty made him taller and broader as well, giving Juan a bigger frame, able to support more muscle. And Ty added it. Lots of it. Juan flexing and posing and groping himself eagerly, as he grew to a six-foot-four, three hundred and eighty pound musclebeast. His genitals grew too, his hard cock becoming a foot long, his balls growing to the size of extra large eggs. Finally Ty stopped, and stepped back, as Juan flexed happily in the mirror, his naked body glorious to behold.
