"Transform!" Ahh, I mean-!" Jen spat from her hurried pussy mouth.
Erika cut her off though, "Like, seriously Jen? All I asked was for both, and you can't even do that? How am I supposed to trust you to change me back if you can;t even talk straight?"
"No, Erika, please, I didn't mean to. I'll change you back on the next one, just change me back to normal now and I can help you!"
Erika's hips shook back and forth in a sassy way, "Nuh-uh Jen, I don't believe you. I think for payback, your transformation will be a nice big living cock."
Jennifer gasped in horror. "No! Erika! Anything but that! I know you're angry at me, but... please, not that!"
"Yes, that. You're going to be a living penis. No legs, just a penis. You'll be four foot long when you're flaccid, but when you get hard, you'll swell up to a nice big ten feet. Like, you won't have eyes or ears or an actual mouth, but you'll still be able to see and hear and speak from your pee hole. You will be able to move on your own like um ball walk and squirm or something, you will have control of yourself, and since you won't have a stomach, you won't need to eat or drink. You won't have to pee either, but you will be able to cum when you get off-- in fact, you'll be super-horny all the time, and you won't be able to satisfy the feeling unless you cum. Your cum won't be able to make me or anyone else pregnant, but it will immediately cause anyone who comes into contact with it to have a really powerful orgasm."
Erika found herself entranced by the sight-- she could not turn away. Jennifer began to grow; within seconds she was the height of Erika, rather than a half. Soon Jennifer's clitoris began to balloon outward, taking on an oblong and distinctly phallic shape. "Nooo!" screamed Jennifer. "Erika! Stop this--!" Jen's voice was cut off as her pussy lips fused together and began to inflate as well. Soon the hulking creature Jen had become was completely laughable in appearance-- a huge bulging penis and balls which were freakishly disproportionate to her rapidly dwindling legs. Before long, her oversized genitalia was way too heavy for her to remain upright, and she toppled back onto what was now her scrotum, which caused her shaft to droop down. At last, her eyes swelled shut, disappearing completely into her flesh. Jennifer Smith, one of the most popular girls in school, had now been reduced to nothing more than a living, giant disembodied penis.
Erika walked over to get a better look. She called softly. "Jen?" There was no response, so Erika once more asked, "Jen?" As she did so this time, she lightly poked the creature with her toe. The reaction was immediate. Jen's shaft throbbed to life, perking up.
"Erika?" asked the Jen-penis in a somewhat more androgynous voice. "Erika... I'm so horny!! Ugh... why the hell did you do this to me you stupid bitch!!"
"I don't know Jen I was curious...."
"Curious about what!!" Yelled the Jen-penis.
Pre-cum dripping and going everywhere.
"To see how much of a giant dick you really are!" Yelled Erika.
"You bitch!" Jen-penis yells as she dick slaps Erika.
