Brendon got back from the gym, absolutely pumped, muscles exhausted, veins throbbing, he felt like a god. When he got back, Monica was awake although still in bed, Brendon joined her and they immediately started having sex, the covers flew over them and there was a huge moaning from both of them and a huge stream of cum flowing out from the bed. A few days later Brendon discovers that he had actually got Monica pregnant! He was overjoyed at the thought.
A few months later...
Monica has her baby and decides to name it Joel. Monica could not have been more overjoyed, of course Brendon was there, him being the father.
15 Year Later...
Joel was now a healthy teenager, slim, sexy, great personality and he was brilliant, his intelligence was astounding! He was pretty much the 'ideal' teenager, the perfect teenager.. Although he wasn't built, he was very thin. Joel went to school, did homework and lived life like any other teenager, little did he know, he wasn't exactly.. normal, there was something different about this teen. One day Joel came home to Brendon and Monica like a normal day, he went up to his room and he began to work. Brendon and Monica had been talking and they thought it was time that they introduced him their little secret. Monica whipped him up his favourite drink which was simply a chocolate milkshake, a lot stronger than normal milkshakes, and added the 'secret', although this time they added a much higher concentration of it. Joel couldn't smell it over the intense chocolate flavour. Joel was called into the kitchen and he took his drink and returned to his room, and sculled the whole drink, he loved it. Immediately, Joel felt a strong pain course through his body. He noticed he was having troubles breathing and moving, as if he was being constricted. He also noticed a strong pain in his crotch. He looked down to try and find the problem although he couldn't remove his pants due to his immobility. He noticed a small buldge in his pants, nothing great, nothing out of the ordinary. But then it began to grow, bigger and bigger, faster and faster, he felt his heart pumping faster and harder. His pants were getting tight and so was his shirt, it was killing him. Eventually, once the buldge has gotten big enough, his pants gave way and ripped to shreds! He was astounded at what he saw. He couldn't believe his eyes, his cock and his balls were at an unbelievable size, his underpants were stretching and it looked like he was wearing a G-string. His underpants eventually gave way and his ever-growing cock struck out in the air, it felt harder than diamond. His balls had expanded and were now the size of footballs inside his ballsack, it looked like his ballsack was going to tear apart. Once it had stopped, he thought it was over. He had a moment to think about what was happening to him. But he was still very hazy especially since he was still aroused and precum was leaking out of his enormous cock. His cock now weighing in at 12kg and 18 inches. His balls were 6kg each. Then Joel's chest began inflating, starting with his abs, at first it simply looked like a flat surface, no definition, but then, out of no where, small curves began to appear, surfacing by themselves, his stomach was tightening and the pain was immense. His abs eventually stopped growing and tightening when they were sticking out 1.5 inches out of his stomach. The pain came to a halt again and it started again after a few seconds, now he couldn't breathe. His traps were growing around his neck and inflating, expanding and choking. The definition came through very quickly, by this time his balls were releasing so much testosterone into his system that the muscle growth effects of puberty were adding onto the potion! His pecs then inflated and his chest was being pushed back and forcing him into an upright position. His biceps were crushing his arms, his forearms were inflating and so were his thighs, eventually he simply lost conciousness. The next morning he got up, got dressed and went to school as if nothing had happened. Then when he went to school, everyone just started in amazement as his spectacular physique. A girl walked up to him, they talked and it ended in him getting a girlfriend.
A few months later..
Joel was deeply in love with his girlfriend at this time, he went to her house and they went to her room. She was aroused, and so was he. He took his clothes off and she saw it, his enormous cock sticking out, and his balls, his pecs, lats, traps, thighs, biceps, everything! She couldn'd stand it, they both got in bed and he shoved his enormous cock into her vagina and he felt so good, he shot off his entire load, 4 gallons.
