"Hey Sean" a heavy baritone called out.
With his dad already out of sight, Sean turned back towards the school to find the source of the voice. He grimaced as he locked eyes with Dominic.
He was gigantic! His red t-shirt bunched up around his shoulders as he waved at Sean enthusiastically. He smirked and started bounding towards Sean down the steps of the entrance, his pecs bouncing with each step.
Sean instinctively tensed up. "Oh no," he thought, "what is he going to do to me?" Sean was frozen with fear; he had all these muscles yet he couldn't move a single one!
He stared on as Dominic nearly charged towards him, until they were just 30 feet away. Wait, does he seem shorter?
"I've been waiting all morning for a pounding." He slowed his pace to a saunter once he came close to Sean. He was already working up a sweat, his armpits revealing a wet spot that darkened his shirt. Sean was hit with a wave of heavy body odor, and felt his constrained prick twitch. To his surprise, he was looking -down- at Dominic, his bulging yet compact frame breathing heavily just under his pecs.
Dominic took a step closer so that his face was just within sight as his body was obscured by Sean's pecs, and he tweaked one of the meaty nipples that hung downward on the mightier frame. Sean's eyes widened as he let out a small gasp, his tool further plumping up and straining against his shorts.
The bully grinned when he saw the fruit of his teasing; a round, firm bulge poking up from Sean's waist. It pulsed and pulsed, climbing up and under his shirt. A wet spot was trailing from his belly button and kept spreading up his polo as Sean felt his face redden. He quickly looked around, suddenly self-conscious again, and found to his relief that most of the other students have already gone inside. The few stragglers either pretended not to stare or ogled without shame. Their bodies, Sean noticed, also seemed to be bursting out of their clothes with dense, bodybuilder muscles. Yet they all retained their boyish faces that Sean recognized as his classmates.
"Did you forget out agreement?" Sean shot his eyes back at Dominic as saw him pouting and looking up with puppy dog eyes. His youthful face nailed the innocent appearance, but was betrayed by the masculine energy he exuded, his engorged traps threatening to swallow his neck.
"Uh, I... uh," Sean stammered, and inhaled sharply as Dominic tweaked his nipple harder.
"I even practiced with the bigger ones this morning" his face twisted into a mischievous smile. Dominic traced one arm up Sean's and pulled it towards his ass cheek.
Sean, with his fear washing away as a wave of lust replaced it, grabbed hard onto Dominic's butt. Damn! It was even bigger than his palm! The "bully" flexed his ass, which prompted Sean to pull him closer. Dominic's face planted right in the crevice between two humongous mounds of pectoral muscles.
Dominic began sniffing at Sean's musk until his chin felt a wet spot. He looked down. Jackpot!
He uncurled his tongue and was just about to lick the prodigious member until the school bell made a shrill ring.
Sean was snapped out of his daze. What was he doing? Was this the sex that his dad talked about? He still had so many questions, but his bully pulled away, looking crestfallen.
"I guess it'll have to wait 'till lunch, 'shrimp.' Heh, you better be ready for me" he grinned, groping one of Sean's pecs before winking and turning around, jogging up the stairs. Sean stared as his enormous ass jiggled in a similar manner as his pecs did before.
