Michael did feel surprisingly energetic, seeing as he was so nervous about the game later that night. “Boy, That milk sure is good!” He exclaimed, going back for another glass. Over the course of the next hour and a half, he drank four glasses of milk, feeling better each time. Soon, he went up to his room and got dressed into his tight football kit, shoulder pads, cleats and all. Just as he was about to leave his room, a wave of warmth hit him and he began sweating. He wiped the sweat from his forehead, but by the time his arm was back by his side, the sweat had doubled. He looked at his arm, as the vein in his elbow pit was throbbing. As he watched it, the muscles below his skin began to throb and pulse, rearranging themselves and getting… bigger? “What the hell?” He muttered, staring at his bicep. Not only had it just grown several inches, but it was a lot more defined than before, and had a thick vein running down its centre. His tricep seemed to have also grown and hardened, alongside his thickening forearm. He moaned as his arms continued to grow larger, large balls of muscle under his skin. “My arms… What’s happening to my arms?” He brought one up and flexed it watching in shock as it went past its original 15” and swelled up to 18, maybe 19? Not only was it bigger, but the fat that had made up a considerable portion of it seemed to have all but disappeared, leaving a ripped mound of muscle in its place. He groaned as he felt his torso stretch, his shirt coming up above his pudgy stomach. His fat began to melt away, and six strong abs emerged to take their place on his torso. His obliques shoved out from his sides as well, just as shredded as his abs.
The slow growth gave way into a quick spurt as Michael’s shoulders shoved upwards, His chest and abs stretching alongside his legs as he gained about six inches in height in mere seconds. His arms swelled to match his new proportions, His jersey now not covering even the top row of his abs. His lower back dipped in as his glutes expanded outwards rapidly. He grunted repeatedly as his pecs shoved out several inches from his chest, tearing his jersey clean in two. His arms swelled, even more, shredding the sleeves as he stood there breathing heavily.
“Fuck. I’m massive. Ugggh, what’s wrong with my voice?” His voice was three times deeper than it had been minutes before. His shoulders hung two feet apart from each other, leading down to a tiny waist and insane 8 pack abs. His pecs were several inches thick, alongside the clumps of veins and muscle that were his arms. His legs were much longer, and his trousers had torn at the knees, leaving the top parts stretched thin by his quads and massive ass. His feet had torn clean through his cleats and socks and had to be past size 20 by now. His arms had to be more than 20 inches around. He must have been 6 or seven inches taller than his original 6 feet, and he was still slowly stretching taller, his muscles still swelling to stay the same size in proportion. His back stretched wider, and his pads snapped, falling away. The shredded muscles on his back formed intricate patterns. His ass and quads finally broke through their constraints, rewarding themselves with another fast wave of growth as now his only clothing was an insanely tight jockstrap.
His jockstrap swelled with the massive meat that was growing behind it, pushing further and further out, revealing a bush of dark pubic hair. His dick finally broke free, standing to full mast at what must have been nearly a foot long. He watched as hair began to grow outwards from his pubes, covering his legs in a thick forest of dark hair. The massive clumps of hair under his arms spread onto his chest, exuding a manly musk. A thick treasure trail ran down the middle of his abs. Michael stepped back, admiring himself in the mirror.
