Rob was in heaven as the big muscle man sucked vigorously on his massive cock. When Glenn grabbed his newly enlarged nuts, Rob couldn't help but let out a loud moan. It just felt so fucking good!
But he wanted more.
Reaching for the box he felt around until he found what he was looking for. With a devilish smile he looked down at Glenn.
"You like big cocks baby? You like big cocks and big balls?"
Glenn hummed in acknowledgement, causing Robs breath to quicken. If he wanted to do this right, he couldn't wait any longer.
"We'll get ready, cause that's exactly what you're gonna get."
With no other warning, he popped his handful of chocolates into his mouth, feeling the wonderful warmth spread through him.
Glenn released Robs cock from his mouth and fell back to watch the transformation take place.
The change started in his arms, his biceps inflating to monstrous sizes, and slowly spread to his shoulders, growing into cannonballs that ripped clear through the shirt he was wearing. His neck thickened as did his pecs, growing to beautifully ponderous sizes with a valley between them Glenn wanted nothing more than to stick his own large cock into and pec fuck Rob silly. Rob groaned as his abs popped into existence, one by one, until a diamond cut eight pack replaced his once flat stomach. His ass plumped up to orgasmically perfect levels while each leg turned into a pillar of muscle.
As his muscles grew, his cock and balls did too. Already enhanced, his rock hard schlong stretched out a good six inches, making it an easy 20" hard on. His balls swelled like water balloons, growing to the size of oranges, then large grapefruits. The added stimulation to his cock cause it to finally explode, dowsing Glenn in a firehouse of white hot cum.
As Rob breathed in and out, his chest heaving beautifully, he noticed that he'd grown at least a foot in height, putting him at just under 7".
"Oh my god." Glenn breathed as he struggled to his feet, still drenched in jizz. "You're beautiful."
Rob chuckled, his voice having dropped into an immensely sexy bass. "You're not so bad yourself. Tell me Glenn, what do you want?"
Glenn looked at the young man with rapt lust. "I want you. Please, I want you."
"You have me." Rob smiled and lifted Glenn into the air, positioning him right above his thick, drooling cock. "You want this?"
"Please." Glenn whimpered. Rob smiled and thrust his hips upward, driving into Glenn like a train.
