Three months after the growth experiment on Michael, his mass gain had got redistributed across his body. His musculature became more proportioned and, at the same time,  his bones grew and his height increased. Always weighting around 950 lb, he reached 10′5″, or some 3.15 meters.  His room was modified accordingly. Only Michael’s penis -to the researchers’ amazement- maintained its relative size.  His slaves black and white gained experience in pleasing their owner, adapting as they could to his progressive growth. Disgracefully, they soon passed away in domestic accidents, one of them on the bed -its chest smashed beneath its owner’s glutes during a restless night- and the other with its head crushed by Michael’s enraged fist, after trying unsuccessfully to make its owner cum by frantically rubbing its full body against the enormous erect penis. In the subsequent years, many bodybuilder slaves belonged to Michael and died by his hand. The giant, ...

After the tremendous ejaculation, Michael’s erection receded a little, and the young giant fell heavily on his favorite armchair. One of the slaves licked off the semen remaining on the huge glans, and the other was ordered to sip and swallow the cum puddle that had formed on the rug, which had begun to dry and harden. It might have interested the lab scientists to know that Michael had ejaculated almost one gallon of semen. Or, as a scientist would put it, exactly four liters.  Michael took advantage of his temporary relief to have a nap before getting erect once more. His exhausted slaves were allowed to rest at his feet. Sooner than later, they would be hyperactive again… (to be continued)  

Back on the sofa, the young giant compared his huge erection with the size of white’s well-muscled torso. What would happen if he fucked the slave? He would not only tear its sorrowful ass apart, but would probably destroy most of its internal organs, and white would hardly survive. Michael decided to pospone this sacrifice, but the magnificent sensation of absolute power on his pathetic property made his erection grow even larger. Meanwhile, black had been ordered to give a deep rimming to Michael’s ass. Really deep… The slave, poor thing, had never imagined having its neck collared by someone’s rectum, with the head well inside the bowels.   Finally, Michael resolved that -being the slaves’  first day in his possession- he would just be jerked off by the well-developed white’s glutes and black’s pecs. After some dozen rhythmic ups-and-downs, a column of thick semen ascended violently well beyond the slaves’ heads and landed on a rug, a few fe...

Michael ordered his slaves -which he playfully rebaptized black and white- to drop their thongs at once: after all, they would hardly need any clothing for quite a long time. The spiked leather-and-steel collars would provide sufficient covering to their pitiful modesty. Standing in front of the imposing two-feet erection, the comparison between the slaves’ and their owner’s sizes was at the same time dramatic and ludicrous. To make the size comparison more humiliating, Michael ordered white to masturbate black -the biggest of the two slaves- until it got an erection. Even erect, black’s glans was barely larger than its owner’s thumbnail! In the meantime, white got buried for the first time in one of the young giant’s  muscular armpits. Its tongue worked inside that humid and smelly space for endless minutes. Michael decided to take a break, and approached the window to have a look at the snow falling outside. He ordered white to kneel down and lick ...

The only unexpected side effect of the otherwise successful growth experiment conducted on Michael -a young  volunteer from a nearby college- was that he couldn’t help being constantly horny, with a huge, permanent erection. Two bodybuilders -inmates, at that time, in the local State prison- were properly geared up and sent to the especially furnished lab room where Michael lived now, to serve as his sex slaves and attempt to alleviate the young giant’s urges. According to measurements taken just after the experiment, Michael’s height was 2.41 m (7′11″) and he weighted 426 kg (939 lb). His muscular strength had not been immediately evaluated, but one of the scientists in the lab roughly estimated it as equivalent to that of a young rhinoceros. Sliding his hands between the bodybuilders’ legs, Michael squeezed their balls and penises and easily lifted them up to eye level, making it clear that they could not dream to rival him in force and power. Their ob...
