"You’re still growing, Dan." Yan said as he compared his clenched fist next to his best friend’s. "Your fist was barely bigger than mine this morning…"
"I know." Dan replied with his deep booming voice, his whole body tensed, clothes feeling tighter, his shoes hurting. "I… can’t control it."
"God… you’re taller as well, huh? This morning, I was looking right at your chin…"
"Yeah…" Dan groaned and let his arm go down, as much as it could go. His arms were so swollen with muscle that they would never point directly the ground even in their relaxed state. Dan felt a sudden swelling in his chest. Gasping he rolled his shoulders. "Ooof…" He bellowed, puffing his chest, which was slowly but visibly growing bigger under his taut white shirt, approaching his chin.
"We… gotta do something…" Yan blurted out, watching with awe yet curiosity. "At this rate, I’m not gonna look straight at your pecs anymore…"
Dan grumbled something, moving his bulky legs further apart. These new stretchy jeans that were a slightly too big a few hours were already straining and threatening to tear at the seams. "Grrr… Bring it on…"
"D- Dan?? Are you even listening to yourself??"
A small metallic PING echoed and Dan’s large patriarchal watch that was handed generation after generation in his family snapped at his growing wrist. The poor object fell on the ground and shattered in a heartbreaking glass-breaking sound.
"F- Fuck…" Dan growled and grimaced, but Yan knew it was not in consideration of the broken artefact. The growing man tilted his head, the face growing suddenly red. His arms tensed and swelled, threatening the tight sleeves to tear at any moment… Then he raised his head up. "UGGGHHH!" A few stitches popped and tore here and there without showing obviously yet… and Yan watched in fear as Dan’s head raised even taller than before, by an inch or two. Yan was no tall man at 5’8, but looking slightly up at Dan’s nipples, his best friend had to be about 6’8 by now… at the very least. The hem of the shirt was starting to show a thin line of skin.
"Shirt… is getting awfully tight…"
"Maybe you should remove…"
"No… I want to burst out of it."
Yan shook his head disapprovingly, looking around if people from the convention were starting to look at them. Indeed, a few were looking in their direction.
"We… should move somewhere else…" Yan suggested.
RRRIP.
Yan’s heart fluttered at the tearing noise. He looked back to Dan who was flexing in his shirt, which was already tearing at the seams, under his armpit as well as on the sleeves.
"Enough!" Yan asserted, taking with force Dan’s arm, trying to get them as far away as possible from the attention. Without resisting, Dan let his smaller buddy lead the way to a nearby restroom, Dan’s head brushing against the top of the very narrow doorframe. As they entered the men’ restroom, while looking at himself in the large mirror over the sinks, Dan finally noticed how big he’s gotten since the day before.
"I’m a fucking giant." He said with amazement, puffing his chest with pride. "Do you have anymore of that stuff, Yan?"
"What?? Don’t tell me you planned on taking anymore!"
"I… Kinda…" He admitted.
"Look… you drank the whole concentrated thing instead of your diluted shake yesterday… I don’t even have anymore for myself! You can’t possibly want any more of it!"
"It was an accident!"
RRRIP. RRRIP. RRRRRRRIP.
The seams of the pants were starting to tear at Dan’s thighs, without even flexing.
"Was it?" Yan asked doubtingly. "Was it REALLY an accident?"
POP. RRRIP. POP. RRRIP.
Dan’s brand new size 15 sneakers popped and tore at the tip, massive socked feet stretching their way out. Even the socks looked about to give. Yan stepped back against the counter, looking with wide eyes as Dan’s head inched even higher to 6’10, 6’11… now topping seven feet tall.
That’s when the pant’s button blew off against the mirror, breaking it, the zipper tore down and a massive appendage bulged out from his crotch.
"Ngghh… not… RRRIP. gonna… RRRRRIP. stop…"
The soft cucumber-sized organ in Dan’s overstretched underwear started filling with blood, growing… and growing in the tearing the cloth. RRRRRRIP.
