"Damn it!" Jen gasped as the bus veered around a corner, and out of sight. She swore and resigned to walk the rest of the way. The only comfort she had was in the warmth coming from her crotch. Jen didn't know why she felt so horny, but the feeling wasn't exactly unwelcome. Her clit felt especially sensitive today, and Jen was thoroughly enjoying the way it rubbed against her underwear.
Even though she was walking down the sidewalk, Jen couldn't help but press a finger against her jeans. Her clit throbbed and her panties became wet very quickly. Jen bit her lip and kept walking, one finger still pressed against her clit. Her face grew flushed and she panted as she walked. This feeling wasn't going to go away, not until Jen....
"Excuse me miss, are you alright?" A voice pulled Jen out of her trance. A car had pulled up alongside her. An attractive young woman, probably a couple of years older than Jen herself, looked worried, and Jen assumed it was because of her own appearance. Wiping some sweat from her brow she politely told the woman she was alright, just late to school. Which was close enough to the truth, so her clit didn't change.
"Are you sure you are feeling alright? Your face looks awfully flushed, and a moment ago you were breathing very heavily." the woman said.
"Thank you for your concern, but I'm alright." Jen said. She'd since removed her hand from the front of her pants. Her clit was begging her for more attention, but Jen had enough sense not to play with herself in front of this lady. This very attractive blonde, who was wearing a tight blouse that showed off her assets. Jen wondered if they were real or not. The woman's breasts were so round and full, Jen could just make out the outline of her nipples through the thin fabric of her shirt and bra.
"Would you like a ride? You said you were late for school?" the woman still wasn't convinced Jennifer was alright. The girl looked sick, like really sick.
"Really? That would be great!" Jen didn't think the woman was untrustworthy.
"No problem. We all have those moments. Why are you late, miss the bus?" the woman asked. For whatever reason, Jen didn't want to admit she'd missed the bus. Which was perfectly logical as all teenagers missed the bus on one occasion. And, more importantly, it was the truth. Still, out of habit, Jen lied.
"I, uh, just had a bad morning is all. I should have known better, but I asked my mom to wake me. As usual, she was sleeping on the job with one of her stupid hookups. It's my own fault really." Jen lied. While that earned her a ride, and the other woman's sympathy, it also caused another transformation.
Jen sat in the passenger's seat, and felt something tingle in her crotch. She couldn't know for certain, but her clit felt different, bigger? It was indeed bigger, pushing out two more inches. Her now six inch clit was starting to look more like a cock. The end was rounded and larger than the rest of Jen's clit. The beginnings of a hole were forming, and clear liquid was dribbling out. A slight tent in Jen's pants gave away her arousal.
"I never caught your name," Jen said, squirming in her seat as her clit was starting to get really uncomfortable.
"Sorry, the name's Liz. What about you?"
"Jennifer, Jen for short. Thank for the ride. I hope I'm not keeping you from something."
"Just the opposite. I'll do anything to avoid going home. See I work late nights, and my dad isn't always the nicest man at seven o'clock in the morning. Guess we both have crappy parents." Liz remarked, believing Jen's lie.
"I'm sorry to hear that. I guess I should be glad at least my mom never had the energy to be mean. If she's not exhausted from plowing some asshole she's drunk off her ass." Jen lies again.
And with that, Jen's clit morphs into a complete penis. Edging out another inch and a half, her clit thickens and pre cum flows freely from the tip. Her new cock is rock hard, and the strange, new sensation grabs Jen's attention. She almost screams when she sees the outline of what is obviously a cock in her pants. Thankfully Liz doesn't notice, but she does catch Jen's face paling.
"Jen, what's wrong?" Liz asked, slowing the car. She pulls over, just a few blocks from the local high school.
"Noth-nothing. Please, just keep driving." Jen stammered. She didn't want to believe it, she couldn't have grown... it was impossible. People don't just grow dicks!
"Jen, it's alright, I won't call the cops or your mom. If there's something wrong, tell me. I know what it's like, being a teenager and all. You meet guys, think they're the one, so you do all sorts of..." Liz assumed Jen was being bullied or abused, based on the girl's erratic behavior.
"It's not like that! Honest. You know what, I'll just walk the rest of the way. Thank you and..."
"Jen I can't let you go. Not until you tell me why you look like you've just seen a ghost. I'm only trying to help." Liz said.
"You want to help, let me go. I swear, I'm not in any sort of trouble. I'm just having a bad day!" Jen all but screamed. At that point Liz unlocked the doors and Jen ran out. But she tripped in her haste, and face planted on the ground. Liz jumped out and went to help Jen.
Turning Jen over to see if she'd hurt herself, Liz saw something she had never seen on a girl. Only on a man. The crotch of Jennifer's pants was tented at least three inches out. The blonde girl lying on the sidewalk with tears in her eyes had a cock.
