Marty was actually excited by his final test. he drove peter to school and immediately headed to the lab. once inside he saw Raven in the lobby before heading to the examination room. the doctors were surprised at the twin cocks on his crotch. "subjects last examination before the final test with the penis enhancing lotion."
"the subject has clearly embraced their new male appearance. most importantly the subject's penis has split into identical cocks. this coupled with the addition of a ninth testicle has shown us what happens when a female is given a penis-enhancing lotion. the subject who had gotten the breast-enhancing lotion only had one side effect. his new breasts leak milk despite not being pregnant."
"The clear difference between subjects is while subject one known as Martha has changed completely. subject 2 known as Raven has not. this is most likely due to the massive surge of testosterone from the subject's testicles. this, in turn, is reflected back at the genitalia and has caused it to multiply." Dr. Alex turned off the recorder.
"now this is your last test so make it a good one. one thing we need to tell you. we are still testing out the penis-enhancing lotion. we do not know its full effects as you can guess. so it will take time to undo your transformation."
"mostly because this is the most extreme case we've ever had. most men get a few centimeters added not several inches." she said before showing Marty to the door. "that's OK I actually decided I like this new body. I'm gonna keep it."
"sure I'm gonna miss the body I grew up with but I'm guessing this new form will make many ladies happy," Marty said. he was soon led into the testing room. like before he was asked to remove his clothes. the mere thought of his genitals growing made him excited. the moment he pulled his underwear down his twin cocks rose to their full height.
he was glad the lotion made sure they were as heavy as they started. that meant while they were massive they were also lighter than a feather. another was his 9 11-inch testicles. these massive orbs were also very durable. he could walk around for hours with their swing and hitting his legs.
he had also worn clothing that left nothing to assume. he then put on the lotion one last time. he made sure to get every inch of his cocks and hairy sack. he soon felt them grow larger and thicker. his cocks grew from 27 inches to 28 then 29 and finally 30 inches. his sack grew as a new testicle dropped into it. this brought the number up to 10 softball-sized orbs in his sack.
he felt his cocks about to release but he held it in. he wanted this last one to be memorable. he felt his cocks grow longer till they passed above his head stopping at 36 inches. he couldn't hold it in anymore and cumed directly on the observation window. however, the force was so powerful and so long that the thick glass cracked, allowing cum to leak through.
this proved too much for the female scientists as they all cumed at the sight of this. when his cocks finally softened they shrank to a foot and a half long. he heard between moans to wait at the front desk. he put on his clothes. he now had what looked like two baseball bats and a sack of softballs underneath his shorts. he went to the lobby and saw raven getting his final payment from the tests.
he now had an impossible M-cup breast on his chest. "hey Marty looks like this well be the last time we see each other here. at least till they can make shrinking lotions for our specific conditions." Raven said. "about that, I've decided to stay like this." Marty said.
"why? not to put a bad spin on this. I mean I like using the milking machine and all that, but it just doesn't feel right to me. I got the biggest boobs that I've ever seen and while it was great while it lasts I do not want to be like this forever." Raven said as Marty waited for his payment. "well I can't really explain it but I feel like I'm finally my true self."
"not to say my old body was bad but I'm now a big man. plus I've found a way to pay the bills till I land a job." he said as he patted his massive bulge. "well if that's fine with you. we should still keep in touch, bye." Raven said as he turned towards the door.
Marty then saw the woman with his money approach him. "here you go and I understand you'll like to keep this look?" she said as she handed him his last payment. "yeah, I really like it" he said as he checked to make sure it was all there. "well in that case if you have any more side effects either call us or just come in" she said as she headed back down the hall. with that Marty was officially done with his tests. When he picked peter up from school they went out to dinner to celebrate.
