Guy pulled on a very large shirt, which was barely able to stretch over his massive, meaty pecs. He smiled at Hiro, and gave the smaller man's ass a nice pat. "Let's go, lover."
Hiro followed the muscle behemoth out the door, and down the street. Guy was now too big for his car, so they'd have to walk. Hiro followed behind at first, watching as Guy's huge legs and bulging ass moved within the tight pants. When Guy stopped suddenly, Hiro walked right into the wall of muscle in front of him, he was so distracted. Guy chuckled with his deep voice, and steered the smaller man around so that he walked to the side. Still, Hiro couldn't help but stare at Guy's massive physique as they walked, much to Guy's amusement.
As they wandered through town, Hiro began to notice that Guy was growing in a certain strategic location. The crotch of Guy's too-tight pants was growing further and further outward, as the equipment within swelled. Guy was having a harder and harder time walking, and finally, he stopped. "Fuck, man," he breathed, "I need to get off so bad!"
Hiro looked around. He saw a secluded alley, and pointed. Guy smiled, and turned, and both men went down the alley, which turned and twisted. At last, they found a secluded spot. With a sigh of relief, Guy unzipped his pants, allowing his big cock and huge, cum-filled balls to fall free. Hiro immediately squatted in front of the big man, his tongue flicking out to taste the bulbous head of Guy's cock. He ran his tongue over it, tasting its manly, funky taste, getting a hint of salty precum with it. The big rod trembled in response, as it swelled up large and hard, pushing at Hiro's face. He opened his mouth, and welcomed the big head as it filled his mouth. Above him, Guy groaned, leaning back against one of the alley's walls, his huge pecs rising and falling in time with his heavy, quickening breaths.
"Oh damn, that's good..." the giant rumbled.
Hiro sucked more of the big muscledick into his mouth, and grasped the thick shaft with both hands. He worked it over with his fingers, massaging the hard, veiny rod. Guy trembled in response, his entire huge body humming with desire, his big muscles taut with exertion. Hiro began to slide down Guy's dick, taking more and more of it into his hungry mouth, using his tongue as an instrument of worship as he did, while his hands slid down to Guy's fat, full balls, and began to knead them expertly. The large man hissed in pleasure, his big hands reaching for Hiro's head. Guy grabbed Hiro, and began pulling him onto his big dick, forcing more and more of his quivering ram into the smaller man's throat.
Hiro pulled fiercely on Guy's cock, eager to milk the big man's cum from him. He was rewarded with a shudder within the big rod, and then an explosion of cum, shooting down his throat, leaking out of the sides of his mouth. Guy was grunting with orgasm, his powerful hips bucking slightly, as his entire muscled body seemed to flex all at once. Gradually, the flow of cum slowed, and then finally it stopped. Hiro pulled off, and wiped the cum from his face. Guy looked down at him, smiling. "Thanks dude," came the rumbling voice, "that was fantastic." The big man stuffed his junk back in his pants, and zipped it up. As he did so, he began to tremble just slightly. Hiro watched with lustful interest as Guy's powerful physique grew even larger, the muscles swelling just enough to be noticeable. The tee shirt stretched even further, the fabric becoming thin as it struggled to contain Guy's massive pecs, shoulders, and back. Guy's arms stretched the shirtsleeves, and even tore the fabric just a bit, while his legs swelled within his already too tight pants, and caused some of the seams to pop open. Guy just smiled, and patted Hiro on the back. "Let's go, hot stuff."
The both of them left the alley, and continued on their way. At last, they reached the shop, and went inside.
