Chris licked his lips lustfully, as he looked down at Dave's bulging, lycra-clad form. He ran his hands over Dave's big shoulders, feeling where the jutting traps joined the thick deltoids. He reached down Dave's front, cupping the big pecs, pressing against hard abs. Then he grabbed the stretch shirt, and pulled it up and off, revealing Dave's impressively muscled torso. "Very nice..." purred Chris. He reached out and gave Dave's nipples a good twist, producing a groan of pleasure from his employee.
Chris' breathing became a bit quicker, and his big cock tented his pants a little more obviously. He reached up with his big hands, and pulled off his own shirt, revealing his tight torso and big, meaty pecs. He bounced them and grinned at Dave, who leaned forward and began to lick the thick slabs of chest muscle. "Urgh... that's it..." Chris moaned, his voice deep and resonant.
Dave's hands traveled up and down Chris's thickly-muscled back, to the large man's pants. As he sucked on his boss' thick nipple, Dave began to undo Chris' pants, pulling them down over the big man's thick glutes and swollen legs. As he pulled them down, Chris' prominent cock pushed against his tight underpants, straining to get free.
Once the pants were to his feet, Chris kicked them and his shoes off. He grabbed Dave's head, and held it in place as the shorter man suckled at his big chest. Chris was getting hornier and hornier, until he couldn't take it anymore. He pulled Dave off, leaned over, and ripped off Dave's spandex shorts, revealing the other man's thick, hard cock (since Dave wasn't wearing any underpants under the lycra, of course.) "Fuck you're a sexy thing, ain't you?" Chris drawled, as he ripped his own underpants off with a savage chuckle, his own thick muscledick stretching to explore its newfound freedom.
The two musclemen examined each other for a moment, lust-filled grins on their faces, fuckrods engorged with blood, throbbing with their powerful hearbeats. Chris was taller, his body well-muscled, his cock big and meaty. Dave was shorter, but his muscles were bigger than Chris', his dick even thicker and longer, now that he was fully hard. Chris smiled at Dave. "Yep, I did good when I hired you, boy." Dave smiled back, "You're pretty big yourself, sir."
Chris smiled, but then frowned just a little. As their boss, he should be bigger than them, shouldn't he? He twisted slightly, and scribbled a quick note on the pad. "Note to self: Need More Muscle. Double!!!" He underlined the word double, and smiled. It was nonsense, of course.
Dave's eyes widened slightly as he saw what his boss had written. His eyes widened further as the big man's body began to ripple and swell, his already large muscles ballooning with size and power, hard bulging slabs of muscle growing harder and thicker, veins popping out everywhere. Chris groaned, his voice deepening, his big fuckrod swelling along with his body. "So... fucking... HOT!" he roared. Effortlessly, he lifted Dave into the air, hoisting the smaller man up, positioning his big cock at Dave's tight hole. Dave groaned with pain and pleasure as his boss slowly lowered him onto that huge muscledick, the big head slowly entering his tight, muscled ass.
Dave grabbed onto Chris' big shoulders, trying to steady himself. The huge delts just swelled, becoming bigger and thicker and harder, the cuts deeper, the veins freakier. Dave groaned as Chris pushed deeper into him, the swelling giant's cock getting thicker and longer by the second. "D- damn, boss!" Dave gasped, "S- so, f-fucking incredible!"
Chris just grinned, a feral look on his face, and started to really pound his big dick into Dave, using his considerable strength to ram it home. Dave groaned with pleasure, feeling the big man swell inside him. Dave's hands were all over Chris' huge arms, feeling the massive biceps, each upper arm over thirty inches in circumference. His boss was a freak among men, a musclegod to make the biggest bodybuilder weep with envy, a man hung with a cock that would make a horse jealous. That huge body and that huge cock were giving Dave the fuck of his life, and Chris was still growing. He pounded harder and harder, his breathing becoming labored, until every massive muscle flexed all at once. With a savage roar, he exploded into Dave, a wave of cum accompanied by a wave of growth in his own body. He continued to thrust his big cock, until every last drop of cum had been deposited. Then he slowed, standing in the middle of Dave's office, his huge chest heaving with each ponderous breath, the smaller man still impaled on his big dick.
