"And with that, the experiment is a success!" the man shouted. Steven watched him do a little victory dance as he contemplated what had happened to him. His entire body felt foreign to him. Looking down at his muscular body, he must have at least be in his twenties now. His huge penis staring him right in the face was the ultimate proof that he was an adult now. "And what was all that white stuff that came out of my pee-pee... I mean my penis? Is that something adults only do?" As Steven wondered what was going on in his body, the scientist had finished his little thing and came back up to him. "I see you are looking at the results of my work, my boy. Or should I say my good man?" "Please. Just let me go. You got what you wanted didn't you?" "Oh no, no, no. A scientist must look carefully over the results of his experiments. It's quite hard to get an accurate reading on your own body after all." "What are you going to do then?" Steven looked at him with fear in his eyes. Would he stick all kinds of needles into him? Age him even more? "Your eyes say you think I'll hurt you, but that couldn't be further from the truth. I simply need to take a good look at your new body. Make sure its healthy."
The man then proceeded to take the urine and white substance and put them into some machine. He pressed a button and Steven felt something move across his ass. The bottom of the table opened up, letting his butt out in the open air. The scientist then took a bowl and placed it under him. "Now if you could take a shit, my good man?" "Wh... What?" Steven was dumbfounded by the question. "Oh do you not know what that means?" "No... No I know what it means, but why do you...?" "Because I need it for my analysis of course. Your urine and sperm can't just be enough." "Please no. I don't wanna take a dump in front of you." "That's a shame. Guess I need to stick something up there." "No! No! Please! I... I don't need to go!" Steven pleaded with tears in his eyes once more. "I saw you hold it in during that transformation of yours." "Ah... O... Okay. I'll do it!" Steven decided he would listen to the man. "Hmmph! Hnnng!" As Steven tired to go, the man took the drool and tears from Steven's face and likewise put them in the machine. "Hmmph!" After a few seconds, Steven pushed out a bowel movement from his open sphincter. "Good boy!" The man took the bowl from underneath. Pressing another button, Steven could feel a machine take toilet paper and wipe his ass clean. He couldn't think that he could be more humiliated than he already was. The scientist closed the door to the machine and turned it on.
"Now while we wait for it to finish, its time to really get an intimate look at the fruits of my labor." The man went towards Steven again and stopped by his feet. "Let's see," he said as he grabbed one of Steven's feet. "It must be at least a size thirteen. And these toes. They have quite a bit of meat on them. These are the feet of someone strong indeed." The man then moved to the legs and gave them a squeeze. "Oh my! The musculature on these things are exquisite. The calf muscles in particular are things most body builders dream off. Hair on the legs about 3 inches or so long?" He continued to move up. "And speaking of hair. This pubic hair! You can barely see the testicles from this bush." The man lifted his balls up. "Ah! Oh! Oh my!" Steven reacted to the stimulation as the scientist felt the weight of it with each hand. The massage caused his penis to shoot up straight again. "Oh! And of course who could forget about this cock!" The man grabbed it with his hands. "Ah! No! Stop!" "Is it a foot long? No... 11 inches maybe? Still impressive. "Ah! Oh god! What's happening?! Why is my penis hard?! Ah! Is there something wrong with me?! Oh!" "Oh no, my good man. It seems you haven't been told yet. You see when a boy reaches a certain age, his penis goes through big changes. And when it gets some... stimulation, then it will become hard like this. We call that an erection." "An... erection? Ah! Oh! Uuuuh!" Steven shot out more of that white stuff from his penis. "Ah! Ah! I'm peeing again!" "Whoops! Oh that's not pee!" the man said as he backed off. "You see, when you stimulate it in such a way, what comes out is not pee, but cum." "C... Cum?" "Yes. Though I imagine you might actually pee a little when you first try it out. Anyway, get this into a woman and you may even be a dad one day yourself."
After a bit again, Steven's penis dwindled back to normal size. The scientist went back up to explore his upper body. "This is real the fruits of labor now!" he exclaimed as he touched his abs one by one. "You grow up to have an eight pack, huh. These pectoral muscles are not half bad either." He cupped them in his hands and pressed down. "Hmm. Hard as a rock. Your nipples seem healthy too." "Ah! Oh!" The scientist tweaked his nipples. He could feel them grow hard as his penis did the same. "Ah! No! Not again! Ahhh!" Once more, he ejaculated on the floor. "Well aren't we a lively one. Enhanced puberty must be more stimulating than I thought." "Oh god! Oh god!" Steven teared up as he continued to be humiliated. "This is even worse then the aging!" he thought to himself. The scientist paid him no heed and continued with his arms. "Like the legs. Quite muscular. And these biceps! If you could flex right now, you'd be indistinguishable from any body builder! The hands came out quite nicely too. These are definitely the calluses of a man in his twenties. And last but not least, the face!" The man took Steven's face in his hands. "Well defined cheek bone. Molars and teeth look good." "Mmgh!" The man sunk his fingers in Steven's gums and wiggled around. "Not much change to the nose though." He took it between his fingers and wiggled his face again. He gave it a slap. "Oof!" "I wonder if that hurt less?" "It didn't... asshole!" "Oh, even your vocabulary is adult like." The man went back down and briefly grabbed his penis once again. "Uhh!" Steven let out one more moan as the scientist went back to the machine to look at the results.
"Let's see. Let's see." The man looked at the screen. "Excellent! I give you a clean bill of health my good 24 year old." "24?" Steven repeated. He looked older than that, but his dad was the same too. Must have run in the family. "And with that, I have all I need." "Oh thank god! Now let me go!" "Certainly! But before I do..." The man reached for a rag and covered Steven's face. "Mmmm! Hmmmph!" "But first, I need to make sure you do nothing to endanger my work. Make sure not to tell your parents or... well I'll leave that to your imagination," the man said to him as Steven fell unconscious once more.
"Uhh... Urgh..." After some time passed, Steven felt his consciousness return. He slowly got up and rubbed his eyes open. He was back outside. "What's this?" Steven looked down. He was wearing a pair of sweats he never saw before. He was barefoot and opening his pants he saw he wasn't wearing any underwear. His huge schlong shown uncomfortably in his pants. Evidentially the man had dressed him. "Well I guess that make sense, but I'm not sure no shoes, no underwear man wouldn't look suspicious." He turned around. The abandoned house was behind him. Trying to open the gate showed it was now locked. "The perv must have kept it open to lure me in." Steven tired to open it, but even with his new found strength, he couldn't just bend metal. The barbed wire on top also prevented him from climbing on top. "Not that I would even find the basement if I got in," he thought as he turned around. The part he was in was obviously new, so who knew what secret passage was hiding it. "This is just fucking great!" he spat out in disgust as he contemplated what to do next.
