Milton awoke to the sound of something thudding slowly in his ear. He lay there, wondering what it was. Feeling the smooth, warm mass under his face. Hearing the distant thumping within. It came back to him. Tim's big chest. His head was resting on Tim's big chest. Milton shifted, his fingers idly running up and down Tim's powerful torso, toying with the big bodybuilder's abs.
"Morning, Josh," Tim rumbled softly, as a calloused hand gently caressed Milton's lower back.
"Morning, Tim," Milton replied, grinning at the huge man sharing the bed with him. Milton slowly sat up, still looking down at the musclegod reclining on the bed. Tim grinned back up at the younger stud, still massaging Milton's back. Unable to believe his luck, Milton took a long moment to admire Tim's fantastic physique. He took in every amazing muscle, not to mention the hearty pole jutting up from Tim's hips, making a circus tent out of the sheets. Something came over Milton, and he pulled the sheets back, revealing Tim's impressive endowment - the man was big everywhere! Milton stared at the quivering shaft for a long moment.
"Easy there, Josh. Just my morning wood..." Tim said, his voice low and soothing.
Yet Milton (or rather Josh, as he was starting to think of himself) was mesmerized by the thick, erect shaft as it swayed back and forth, hard and hearty. Acting on instinct, Milton moved toward it, and began to lick the fleshy head.
"Easy there... J- Josh..." Tim sputtered, as a groan escaped his lips. Milton's tongue was magic, and the hulking bodybuilder moaned with pleasure as his big dick was serviced. "You- you don't have to..."
"I want to!" Milton growled, pausing only for a moment before diving back down onto Tim's cock, sucking more of it into his hungry mouth. Tim let out bestial growl of lust in response, much to Josh's satisfaction.
Milton had never sucked cock in his life, but Josh was a pro. In moments he had Tim writhing in ecstasy, the big man's muscles tensing and spasming all over as he gripped the sheets, moaning in his deep voice, loving what Josh was doing to his dick. Tim's big chest rose and fell as he took deep breaths, his grunts and groans getting louder and more forceful as Josh took in more and more of the big rod, finally inhaling the entire eight inches! After several long minutes of Josh's expert attentions Tim came, shooting a big load down Milton's throat, grunting heartily.
Milton was shocked by the taste of cum in his mouth, but he still swallowed every last drop, impelled by the emerging Josh personality. His muscles swelled in response, becoming larger, more powerful, as the Josh personality gained ground. Milton's own dick was hard as a rock, oozing pre. Acting on instinct, he moved between Tim's big legs, slowly massaging the big bodybuilder's quads.
Tim looked up, and gulped as he saw Josh's thick pecs and mighty arms. He could almost swear they had gotten bigger! Then he looked down at Josh's hefty cock. Definitely bigger. Tim had an idea.
"Come on, Josh," Tim purred, his voice low and seductive. "You're looking sexy as hell! And that cock! Looks like you need some release!" Tim reached down, and started to massage his own powerful glutes, spreading his legs, trying to entice the young Adonis that shared the bed. "I'd love to have you fuck me, Josh..." Tim growled softly, working his ass over slowly.
Milton took the bait. He surged forward, slamming his hard manhood into the recumbent bodybuilder's welcoming hole. Tim gasped, back arching, as he felt Josh enter him. It hurt, but in all the right ways. "Awwww yeahhh..." he moaned, urging Josh on. Josh needed no further encouragement. He thrust his dick deep into Tim, pounding the big man with expert precision, a veteran love-maker enjoying fresh prey. Tim howled with pleasure, gasping as he was thoroughly fucked by the young stud. Josh grunted in satisfaction with every thrust, driving his dick deeper and deeper into Tim until he was finally all the way in, his body alive with power as he fucked the big bodybuilder. And as he did, Milton swelled further. His muscles growing larger and larger with every thrust, stronger and more powerful. Tim watched in awe as Josh grew, loving the sight of it, loving the increasing strength of Josh's movements, the increasing size of Josh's body and tool.
Josh grunted and groaned, thrusting hard and deep, enjoying the feeling of muscleman ass around his dick, enjoying the feeling of his own body as it became more powerful. His utterances became deeper, more powerful and manly as he fucked Tim, his big balls churning as they prepared for what was to come. And at last it did. Josh's muscular body tensed up all over and he shot a huge load right into Tim. The younger man's body growing noticeably larger and more powerful as he came. He collapsed atop Tim, crushing the huge yet now smaller bodybuilder under his bulk. Tim moaned with joy, running his hands over Josh's greatly more glorious physique.
When he was finally finished, Josh slowly sat up, and pulled his dick out of Tim. He got out of bed and padded away to the bathroom, his huge back, thick legs, and powerful ass driving Tim wild with every step. Moments later Josh returned, grinning softly at Tim. "Um, hope I didn't get out of hand there..." Milton mumbled.
Tim shook his head. "You were fantastic!" the bodybuilder proclaimed. "And big!"
Josh looked down at his big body, at his huge, thick pecs that blocked so much of his view. He took in a quick but deep breath. It only made the effect more dramatic as his chest expanded.
Tim got up out of bed, and walked over to Milton. "I think you're bigger than me now, Josh!" Tim exclaimed. "Ready for a pose off?" Tim jokingly flexed his biceps and looked over in the mirror. Josh quickly followed suit, mimicking the pose.
Josh was clearly bigger.
