"What the fuck? Sarah!"
There it was. The spark. Jen was glad she had went around and told every student in class not to leave and not to use their phones. The same went for Mr. Love. No need to start a riot in the school. Best to contain the chaos here for now.
Sarah started, looking back at her friend Julia. Her mouth dropped. "Julia," she gasped. "You've got... green skin! And your boobs are huge!"
"What?" Julia screamed.
"Sarah, you've got a dick!"
"Oh my god."
"Rob, is that you? You've got tits! 4 tits!"
"Where the fuck did these arms come from?"
"Laura, you have horns!"
"What about you, you've got 3 eyes!"
"What do you mean, two dicks?"
All around Jen students were coming to realize the changes done to them. There were tears and shouts. Some students sat still, thinking that maybe their horniness was maybe a result of all this too. Karyn, especially, had gone so long being so horny that Jen thought she might jump the nearest girl to her. Jen thought she'd get the ball rolling in that direction.
"Sarah," Jen whispered. "Become twice as strong as Karyn without gaining muscle mass. Sarah, turn Karyn over and fuck her from behind. Karyn, let Sarah fuck you."
Sarah, who was in the middle of trying not to touch her dick while still trying to figure out if it was real, suddenly stood up. She walked over to Karyn, tripping on the way. Karyn, was facing away from her, so Sarah pushed her over Karyn's desk, and ripped off her skirt.
"Wha? Sarah?!" Karyn yelled.
Sarah didn't say a word, just aimed her dick into Karyn's sopping wep pussy and started going at it. Karyn nearly came right there on the first thrust, she had been so horny. She closed her eyes, bucking against Sarah's hips.
The curses and screams died down as everyone noticed what was going on right in the middle of the classroom. Jen noted several students masturbating already.
The talk of the room returned, but in a different tone.
"Can I touch em?"
"I like your new arms..."
"Do you think they'll both fit?"
The students who were masturbating suddenly found themselves with assistance. Carlos, who seemed to have no apparent changes, suddenly realized that he had an oral fixation that could only be cured with a dick and he found one in Katie, who was all too happy to pull down her pants to let him at it.
Not everyone got into it. Some were still freaked out. So like a camp counselor setting the lonely kid up with a partner, Jen gave little promptings here and there.
"James, you find Julia's skin and boobs to be a huge turn on. Julia, you are extremely turned on by James' new feminine figure."
"Rachel, you find Rob's face to be the sexiest thing you've ever seen."
"Alexis, grow a dick and fuck the first vagina you come upon."
That ought to do it, thought Jen, smiling at her work. It was then that she noticed Mr. Love cowering behind his desk. Jen smiled, waving two of her hands as she walked over to him.
"Get away from me!" he yelled. "You did this, didn't you? Away!"
"Charles, calm down," Jen said. The effect on him was immediate, but he still looked scared and wary.
"What's going on?"
"You were right. This is my doing. I changed everyone. I made them want to fuck each other."
"H-how?"
"I told them to. Just like I'm going to tell you to."
"N-no, you can't make me do anything."
"I think you can see that I can. Let's try something simple. Charles, take off your clothes."
Mr. Love stood up and removed his clothes, all the way down to his underwear. Mr. Love was an older teacher, late forties, had let himself go. His penis size wasn't too impressive either.
"Charles, become younger, until you are 17."
Wrinkles faded, hair grew back, fat wasted away.
"Ah much better. You were actually quite the stud back in the day," Jen smiled, then began to remove her own clothes. "Do you think I'm pretty?"
All around them were sounds of lust, moans and gasps and shudders, but Mr. Love's eyes were focused on Jen.
"What?"
"Do you think I'm pretty?"
"I...I guess."
"Would you like to fuck me?"
"I can't."
"Of course you can. You're below the age of consent, just like everyone else in here. Charles, grow your dick until it's 12 inches long and an inch and half wide."
Mr. Love gasped at his new erection, this phallic beast he never even dreamed of having.
All of Jen's clothes were off at this point. She leaned over Mr. Love's desk, presenting her waiting pussy, and whispered to herself, "Jen, your pussy can take any size dick."
She thought she'd have to give Mr. Love a little bit of extra incentive, but then she felt his young hands on her hips, and smiled.
