Mr. Smith turned away from the board and looked out at his class. He gave a sigh of disappointment. With only nine students, his senior sex Ed. class was one of his smallest. He was going to have a lot of fun changing these guys in the way he saw fit.
Mr. Smith addressed the class and said, "I'm glad to see you're all following the rules." He gestured at the underwear they were currently only wearing. "It's important that you listen to me this class. We are going to be having a very special lesson today. First and foremost, I read in your student files that each of you is already eighteen. That's important because this class will be a little more intense than our previous ones. We are going to dive deep into what it means to be a pervert and we are going to do so by class presentations. I hope you're all prepared to do your best."
Mr. Smith smiled at the class and sat his naked ass down casually on the front of the desk. With his right hand he began to slowly stroke his veiny cock. He felt a bit better about himself now that the class was age appropriate. The last straggling 17 year olds in class had arrived at the appropriate ages for his "material" as soon as he said the word.
He noticed one of the guys in the back, a pudgy nerdy kid not paying attention. It made his blood boil. He called on him.
"Kyle, I mean, Timothy, since you're busy not paying attention to class why don't you come to the front first."
"Whatever," the pipsqueak said, "Everybody knows this class is an easy A." Timothy walked from the back of the class to the front and stood with his arms in front of his baggy tightywhities.
"Now Timothy," Mr. Smith said in an admonishing tone, "Leave that kind of attitude for the debate team."
Timothy didn't say anything. He just stood there so Mr. Smith got up and said, "Timothy why don't you face the class." Timothy did and one guy in the class started to laugh at him.
"Look at that nerd!" Mr. Smith eyed the offending person. It was Jimmy, the head cheerleader and the prick who lead the cheerleading team in sexually teasing the mascot. Jimmy wasn't wearing underwear as he had been wearing the kilt of his uniform prior to class beginning.
"Now Jimmy, you know it's not polite to make fun of people. Why don't you come up here as well. To prove to Timothy here you're sorry, I want you to suck him off."
Jimmy practically pranced to the front of the class and plopped down on his knees in front of Timothy. "Ok nerd, just don't cum in my hair." He said.
Mr. Smith hated a bully but he had a class to teach. Jimmy started to work on Timothy's flaccid and tiny cock. Swirling it around in his mouth. Mr. Smith went back to teaching.
"Class, this is called exhibitionism. Some people really enjoy having sex in front of others like Timothy here."
Timothy went from having a mild blush to being more vocal. "Aw yeah. Suck it bitch. Show them how it's done." He moaned, his voice still squeaky.
"Now class, what characteristics do you think would make Timothy here a better exhibitionist?" Mr. Smith questioned the room.
"He should be better looking." One guy said with a laugh.
"You know what. I think this class could use more manners." Mr. Smith said with a frown still jerking his dick to the scene in front of him.
"Let's see, over the next few minutes, let's watch as Timothy turns into Jimmy's idea of a perfect exhibitionist."
Mr. Smith smiled. He was trashing these kids a good lesson about being nice to one another.
Timothy grunted as he felt himself grow a little taller. His pale skin darkened to a deep tan. He began to thrust his hips more as Jimmy continued to suck him.
Pretty soon, Jimmy coughed and gagged as the dick he was sucking ballooned to the back of his throat unexpectedly. Timothy pulled him off and picked him up. Easily pulling the now smaller man into a standing congress and pounding him for all he's worth. The slap slap slap of Timothy fucking Jimmy was overpowered by the sounds of Jimmy's moans.
Mr. Smith now at full mast said, "Let's hurry this up. Jimmy since you're learning how to be more respectful, why don't you finish first."
With that, Jimmy let out a howl and sprayed Timothy's torso with his spunk.
Timothy dropped Jimmy on the floor and before he could object, he painted his face with a massive blast of cum. After five or six shots, Mr. Smith said, "Alright Jimmy, back to your seat."
Timothy stood there panting, his body completely changed and his cock still semi hard.
Mr. Smith eyed the changes respectfully. "Obviously, for Jimmy, the ideal exhibitionist is a tan and hung stud who only cares about getting his rocks off." Timothy grinned as this became true.
Mr. Smith continued. "I think some tattoos would really help Tim here show off his looks. What if he had some imaginative tats?"
A dark tribal band creeped across Jimmy's left arm and a sleeve appeared on his right. He also gained two interlocked Mars symbols on his upper thigh.
"Also, a good exhibitionist wouldn't wear boring underwear like that." Mr. Smith said.
Instantly, the white briefs morphed into a highlighter green jock.
"Also, I figure a true exhibitionist that looks like you would probably be a bit of a himbo." Tim's eyes glazed over as he lost a bit of his IQ.
"A true exhibitionist might need to jerk off every time he's in a crowd. Luckily nobody will mind if Tim jerks off or has sex in public." Tim began to jerk it again.
Finally Mr. Smith said, "A himbo exhibitionist like time should be willing to fuck anybody who wants him to. Tim eyed the rest of the class but nobody offered to let him plow them so he kicked the green jock over to Mr. Smith and walked back to his desk. Tim sat down but put his legs over top of the desk and continued jerking so that anyone who wanted a good look would get one.
Mr. Smith picked up the discarded kick and gave it two good whiffs then wrapped the bright pouch around his crotch and continued jerking with it.
