Katie turned away from Tiff, not wanting her friend to watch her masturbate. Because she just wanted to get this done with she didn't bother to wash her hands and was unaware that there was still some BE Cream on them. The instant she put her hands on her penis she forgot most other things too. Never before had she realized how good it felt to touch and play with it, no wonder guys seemed to think of sex so often.
Her hands slid smoothly up and down its length, but soon she realized that her hands had farther to travel with each stroke of her shaft. Looking down at it she saw the reason, it was at least twelve inches long, proportionately thick and getting larger. Veins pulsed along its increasing girth as it grew with each throb. Since she had taken the normalizing elixir she didn't find anything wrong with the growth that she was seeing, if anything it pleased her because it meant that she had more to work with. As it neared eighteen inches she realized that she was having a hard time fitting her hands all the way around it and she realized something else too, something very interesting, a few inches longer and she would be able to put it in her mouth.
Normally the idea of putting a penis in her mouth would have disgusted her, but this was her own penis, not that of some other person and it felt so good to stroke and rub it that she was sure putting her lips around its head would feel even better. Pulling it close to her chest, bending her neck and sticking out her tongue she was able to lick the very tip sending waves of pleasure down its length. She continued to lick at it until it grew enough that she felt the head brushing against her lips. Taking it into her mouth she held back a groan of pleasure. She was right, sucking on it felt even better than rubbing it.
It had finally stopped growing, but she didn't notice as she was too caught up in her approaching orgasm. Her pussy seemed to tighten up, which triggered a wave of pleasure rocketing up the length of her penis, ending with a blast of cum into her mouth. She swallowed every last drop, surprised at how much she likes the salty flavor. Finally she let her softening penis go and watched as it shrank down to about sixteen inches and over an inch in diameter, so long that it was visible below her skirt. It was a pity that she wouldn't be able to wear skirts or shorts anymore, but something like that was a small price to pay for the fun that came with having a penis. Wiping her hands on her skirt she turned around, "Alright Tiff, I'm done. Do you want to keep looking around in here?"
She took a step and felt her penis swing and bounce against her legs. If its movements had been frustrating before, they were even worse now that it was so much bigger. At least she had found a way to make her breasts larger and her penis was fun enough to have to help make up for what a problem it was.
