Mike soon realizes that his cock is useless.
HE IS A TOTAL BOTTOM. The only thing that his dick is use for is to pee. The semen builds in his balls making them fuller and heavier with unused seed. HE NEVER CUMS AGAIN.
Mike's great mass and huge arms, pecs and comparatively tiny waist made it impossible for him to masturbate himself needing someone else to try to stimulate him.
This was not what he wanted but as he looks over at drake he begs him to fuck him now. He needed some pleasure and was hoping that it would stimulate his prostate so that he could cum. It didn't work. His prostate was so muscled just like the rest of him he was unable to be stimulated due to the musculature. He asked drake to ride his cock which Drake did and that was no easy feat. It was long and took him hours to just get the cock past the opening. He rode it inch by inch rubbing Mike raw till he was resting on the muscled abdomen. Almost in agony Drake was lifted and dropped on Mike's cock over and over and the cock didn't even get hard. Being as muscled as the rest of Mike it was stiff but it wasn't hard or to the point of stimulation.
Mike wanted to cum and plead with Drake to suck him. This too was a challenge, almost dislocating his jaw.
Drake was exhausted from trying to get Mike off with no effect.
Drake was forced to buy progressively larger dildos to try to stimulate Mike graduating to using a traffic cone. Mike would ride the cone while Drake would masturbate, suck or ride Mike's cock.
What had Mike done. He loved his muscle body but now there was no way for him to relieve his sexual frustration. His balls got larger and hug lower and lower requiring a specially designed jock strap to hold his heavy balls close to his crotch. When released from these constraints they would drop with such force that he would wince in pain.
Over and over Mike tried to change this part of his transformation with no effect. He was stuck as a true total bottom and never relieved of to growing semen.
