“Just drink this down,” I said to Aaron, reaching into the backseat with the coconut water I’d spiked. "It’s coconut water, it’s more hydrating than Gatorade.“
"Good, I hate Gatorade,” Aaron said, yawning.
“Really?” I said, “I’m surprised. Most guys love it. But then again most guys are also hairy, sweaty, muscle-obsessed horndogs who wear tank tops and are obsessed with their cocks.”
“I am not like that, Jon, and you know it,” Aaron said. "I didn’t even want to work out today, you know I think it’s dumb.“ It was true, it had been hard to even get him to wear a tank top.
"I think that’s about to change, dumbass,” I said, turning around with a mischievous smile on my face. Did you finish that bottle of water yet?
“Yeah,” Aaron said, scratching absently at his chest. "Yeah?“ he said again, sounding confused. "Aww, I’ve gotta flex” he suddenly said, and as he did I could hear the cracking of muscle as he started to swell up. Aaron’s eyes were wild, but he couldn’t stop flexing as his biceps started to swell with serious muscle and he started to take on a more masculine expression. Hair was starting to spout up in his pits as he held a flex. He was staring straight at me in a flushed panic, and soon it was sprouting in the center of his chest as well, rapidly spreading outwards and across his torso. "What’s happening,“ he managed to get out as he let his inflating arms collapse to his sides for a moment, but a few seconds later he already felt the compulsion to flex again. His biceps mounded up even harder, his shoulders broadened, and I could see hair starting to sprout up towards his collarbone. He had started getting stubble on his face just before his chest started to loose its smoothness, but by now he was already sporting almost a full beard. "FUCK!” he yelled out in a voice that had dropped by a full octave, going unwillingly into another hard flex. "What the fuck man!“ he said, panting, as the changes slowed down to a stop. I could tell from the bulge in his pants that he wasn’t as entirely upset as he sounded.
"Flex for me, fucker. Maybe you’ll get to let that bone out if you do.”
“What the… yeah, I’ll flex for you, you dick. I don’t know what was in that shit, and you should have asked me. Though holy shit, look at my chest, man. Holy fuck, I feel cocky or something. I gotta get this dick sucked man, I feel so horny for no reason.”
“It’s in the water, you fuck,” I said, leaning back and grabbing his hairy chin with one hand and learning in so we could wrestle our tongues in the backseat.
