Mr. Smith looked at the first student he had changed. An exhibitionist himbo was an ok start but it wasn't nearly perverted enough. He had work to do to teach these kids. He had to think. This wasn't going to be good unless he put the work into it.
Then it hit him like a lightning bolt. One of the best ways to teach is to teach what you know. He spoke up. "Another form of perversion is incest. It's an important topic to discuss in this class."
Another boy in class rudely spoke up, "Are you going to bring Blake in here so we can watch you fuck him."
Mr. Smith shifted his eyes from the jerking hunk in the back row to the student in the middle who had called him out on his perverse actions with his son. "William, my family business is none of yours." He scolded politely.
"Tell that to Blake. All he does is run around school and convince guys to fuck him but then goes on and on how nobody can give it to him like daddy." William complained.
Mr. Smith's erection bobbed and swelled with a bit of pride and a bit of shame at having his sexual life being made so public. Instead of changing the subject though he decided to double down on the lesson.
"William since you're so intent on talking about incest, why don't you come to the front."
William got up and came forward facing his class.
"Ok." said Mr. Smith. "Let's begin your lesson on incest. First and foremost, your name is William but everybody calls you Bubba." William shifted uncomfortably in his boxer-briefs as his name changed.
"You're in this classroom but I don't think you're a student. How could you be? You're 35." Mr. Smith continued.
Bubba aged up to 35 he looked good. He had aged well and his boyish charm had changed to manly ruggedness and his chilled jaw and striking eyes made him a sight to see. But Mr. Smith wasn't done.
"You must be here to clean up the cum. You are the school's janitor."
At Mr. Smith's words, Bubba was no longer clad in just his underwear. He was wearing the janitor's uniform he always wore to work. In his right hand was the mop he used to clean up cum all over school.
"It's a weird day when I actually get to one of these puddles before Benson does." Bubba said to Mr. Smith. He swiped his mop around and dropped it back in his bucket. "We'll, I better get going." Bubba moved to take a step to the door but Mr. Smith stopped him. "Why don't you stay for a bit. I'm working on student presentations and you'll be interested in the outcome of this one. Relax. Unzip your coveralls like you normally do. Get some air on that furry skin of yours."
Bubba did as he was told and unzipped his coveralls displaying a toned but now furry physique.
Mr. Smith acknowledged the change in comportment and said, "Did you get that jockstrap out of the lost and found. That's pretty gross." Even to the altered Mr. Smith that statement sounded kind of hypocritical but still, Bubba's briefs changed to an off-white and sweat stained secondhand jock.
Bubba shrugged and said, "Perks of the job."
"Well there certainly are few perks to this job. You currently live in a single wide behind the field house. You can't be making much money but you were desperate when you took this job. You see back when you were sixteen, before you realized you were into men you had a one night stand with a girl from across town and knocked her up. Nine months later you got a basket on your door with twin baby boys and a note that said your four inch dick wasn't worth the trouble of a shotgun wedding. You went to the principle at the time and explained your situation and that your parents were kicking you out and he let you drop out of school and get this job. All that stress and responsibility. No wonder you let yourself go. I guess judging from your choice of underwear, your hygiene is lacking too."
Bubba's head was spinning. Everything Mr. Smith was saying was true. He lived a sad life in a smelly trailer. His work sucked. He was poor and had a tiny dick. But, all his sacrifices were for his family. The two boys he'd raised for the last 18 years.
Mr. Smith turned his attention from the fat smelly janitor to the rest of the class. Out of the seven boys left. He called two at random.
"Daniel and Nathan. Come forward." Mr. Smith didn't even waste time looking them over. He decided for a total rewrite.
"Daniel and Nathan. Your names are now Travis and Trip. You two are the identical twin sons of Bubba here. You two are a couple of burnout studs worried about working out, smoking pot, and busting a nut. You're both as hairy as your dad here but blonde. You strut around in the single wide trailer in dirty jockstraps with your constantly leaking, monster-can-sized cocks dribbling pre all over the place. You like to fool around together but you always end up arguing over who's going to top or bottom. Your problem was solved last year when you caught your pervy dad watching you jerk each other off in your room. Now, you argue over who gets the top and bottom of your dad."
Mr. Smith watched as the two guys went from two completely different young men to two crazily similar young men intent on railing their dad every chance they could.
Bubba, you love bottoming for your sons and even look for excuses to break them out of class to pound you in the janitor's closet. You've all been working up to the day when you can get DP'd by them. I think today is the day. Boys do you want a hall pass?
Travis or Trip, it didn't matter one bit to Mr. Smith or Bubba for that matter reached out for a hall pass while the other twin lifted up his own armpit and got a good whiff of his own stank before reaching down and adjusting his leaking cock.
Bubba looked embarrassed but eager to leave with his boys and get them into the janitors closet. The boys had been really eager to get this going so neither had to fight for the hairy hole each time.
Quickly, the trio left the room seeking the comfort of the tiny janitor's closet to do their work.
Mr. Smith looked at the five students left needing to be changed.
