As the incantation was recast Marco could feel himself growing bigger.
NO! He bellowed pleading for mercy.
You wanted to be a huge muscle man and now you are the hugest of muscle men. But I have a surprise for you once you finish.
Marco had become comically huge. A cartoon couldn't have been more ridiculous. But you can't stay here. You must have a place to play.
As those words were said the walls began to fade and he found himself on his hands and knees well his pecs and knees. His arms couldn't reach the floor. They were actually flaying about because they couldn't reach around the muscles on his chest, or his biceps. His abs went to a 40 inch waist which would have been a lot thinner if he had been an average muscle man but with a 300 inch chest and foot round nipples going down to his 400 inch hips the waist was a comically small 40 inch. This gave access to his cock which, although big looked like a micro wiener on him. The 9 inch cock that was almost 6 inches in diameter looked like a 2 liter soda bottle but on him it hid in his crotch. His legs spread out and his knees rested on the floor at an angle to his hips leaving a six foot access to his ass. His jaws were muscled but there were so many muscles in his jaw that he couldn't close his mouth. This caused an almost constant drool and access to his throat.
Just about done Mr. Mendes said.
What now.
Release the horde. Mr. Mendes demanded.
Some great big sliding doors opened and hundreds of men came to have their way with Marco. But Marco wasn't the only one changed. As each man had sex with Marco their cocks grew. They had to his ass cheeks were so stiff that an average sized cock wouldn't have even penetrated him Their cocks had to be long and stiff and able to resist the constant clench that Marco had no control over. As they mounted him their cocks would grow 6, 7, 8, 9 or 10 feet long to access his ass. Now the ones that fucked his face didn't need to be long but any access to Marco had the same effect on the men. Face fucking him their cocks would grow and shove their cocks deep inside his throat and into his stomach feeding him their man juice, which would be what he lived on.
As they men pulled out they would have their huge cocks that would eventually soften and become somewhat smaller but a 3 foot limp dick was still quite a sight.
Marco stayed muscled and entertained for a long long time before Mr. Mendes decided to make another change to Marco.
