Katie broke into a cold sweat as she felt the tingling concentrate in her mouth, her tongue especially.
Sticking it out, she tried to get a good look at it, to see just what the vial was doing. It seemed as if the
vial was not doing anything, but as soon as she was about to waive the vial off as a stupid chemical when she
felt her tongue change. The change started with her tongue fattening up, not changing width any, but it got
taller. Next, it extended to six inches out of her mouth, and turned tan. Veins started to cross her tongue,
and the mushroom head of a penis capped it. The last change to her tongue was the color change from pink to
tan. Once the transformation finished, the cock started to get hard, and stuck straight out of Katie's mouth.
For the first time in her life, Katie was truly scared, here was a chemical which had, in the space of less
than 30 seconds, transformed her tongue into a penis. What else would it do?
"Tipph, hepph me!" Katie cried out.
Tiff, which had been repeating, "Oh my God," like a mantra, was snapped out of her reverie and said, "Omygod
Katie! I knew you shouldn't have drank the chemical! Now look what you did!"
"I knowph! Jupph hepph me!"
"What should I do?"
"I haph no ihea, somephing!"
Seeing no other way of doing anything, Tiff grabbed the cock. Katie moaned in pleasure at touch, and she
wrapped her own hand on the cock. Sliding her delicate hand back and fourth, Katie's pleasure intensified, and
it showed in her soaking wet panties. Climaxing, Katie shot her load all over Tiff, then laid down.
"Ewwww Katie, how could you?" Tiff exclaimed at the mess she was. While Katie was resting from her first
ejaculation, her cock had softened and slithered partway back into her mouth.
Getting up, Katie found that, when not aroused, her cock acted like her old tongue and could speak normally.
When the cock was limp, she could stick it out and it would end up about 4 inches away from her mouth. Katie
found that the normal position for her cock to be in was sticking all the way out, and that she had to think
about it to pull it into her mouth.
"Tiff, I think we should get out of here." Katie said nervously. While Tiff was a timid girl on the outside,
she had a few very interesting fetishes, strange cocks being one.
"Katie, I love you!" Tiff said at a spur of the moment, and threw herself onto Katie, french kissing her.
Katie, even though she was only a sophomore, was an experienced kisser, and kissed back on reflex. On
Tiffany's end, she had the erotic experience of kissing her best friend and having a cock down her throat. On
Katie's end, she was getting the first blowjob of her life. Tiff, inexperienced but lucky, moved her tongue
around Katie's cock, pleasuring Katie a great deal. Katie got nervous about this, realizing that any kissing
beyond pecking would result in them finding out about her cock, but her thought was incomplete as the pleasure
from the blowjob soon made her ejaculate down tiff's throat.
After recovering, Katie realized that her bladder was going, so she excused herself to look for the lavatory.
Running down the hallway, the 4 exposed inches of cock slapped against her face as she tried to find a toilet.
Finding a men's room but not a women's room, she ran inside to find there were no toilet bowls in sight, only
urinals. She was about to run out again to find the women's restroom when she felt a different pressure
forming in her cock. Figuring out what it was, she aimed her cock into the nearest urinal and let go, the
urine falling all the way from her face to the smooth porcelain below. Idly, Katie wondered if she would ever
piss from her normal spot again. Having relieved herself, Katie started heading back to Tiff.
Meanwhile, back in the lab, Tiff was eyeing the shelves of vials. She recognized the acronyms to a few, but
she kept the AP vial in the back of her mind. Tiff wouldn't mind having a dick, even if it wasn't in her
crotch.
Tiff saw one she liked, so she took it down, uncapped it, and took a swig right as Katie returned.
"What on earth are you doing?" Katie demanded of tiff, and snatched the vial from Tiff's hand. On the label,
it read...
