With four students down, and five to go, Mr. Smith looked from young man to young man, pondering who to manipulate next. Timothy was in the back, groping himself, trying to catch the attention of the other guys in the class. Mr. Smith didn't want him interfering, necessarily. "Timothy, you did such a good job on your presentation, you're excused for the rest of the period. We all know you'd rather be in the hallway anyway, looking for guys to fuck in public. In fact, why don't you go find where Bubba and his two boys went? You love having sloppy seconds on that filthy janitor's hole."
"Fuck Mr. Smith, thanks! That sounds fuckin' hot," Timothy said, standing up from his desk and hurrying out of the room. He didn't have any clothes to put on, of course--Timothy always showed up to school wearing nothing more than one of his brightly colored jocks.
"There. Now, who will be presenting next..."
Jimmy, who had sucked Timothy off and then been fucked on his massive cock, was sneering at the jock as he left the classroom. It was clear that he hadn't quite learned a lesson from his earlier experience. "Something on your mind, Jimmy? You can share it with the class."
"Nothing really Mr. Smith, just thinking about how fucking crazy Timothy is, showing off his body, humiliating himself like that all the fucking time."
"Ah, but that's a bit of a misunderstanding of where Timothy's perversion comes from. It's not that he wants to feel humiliated, it's that he wants to perform, and he wants people to see and notice him. He doesn't care how people feel about what he's doing, whether they want to watch or not, the mere act of having a witness is what drives him. Why don't you come up here, Jimmy, and we can demonstrate the difference between that, and humiliation."
Jimmy rolled his eyes, but did as his teacher suggested, already fully naked as he had been before. As the head cheerleader, he was quite muscled and took great care in his appearance. He was regarded as quite the stud around school, and often was seen with an arm around a different boy he was fucking each week--often one of the other cheerleaders, or one of the football players.
"Now class," Mr. Smith said, "Humiliation is altogether different than exhibitionism. It does have a component of witnessing, yes, but rather than the simple act of being seen in a sexual act, the pervert with a humiliation fetish, like Jimmy here, is thrilled by being seen in an embarrassing position or appearance, thrilled by the risk of losing physical or social status."
Jimmy shuddered at the description, his cock getting a little erect at the prospect of what could happen to him up in front of the class.
"Now, Jimmy is used to showing off in public. He had no trouble sucking Timothy off just moments before. No--he would require something further to be...properly humiliated. Why don't we take some suggestions from the class, eh Jimmy? See what your peers think would properly humiliate you, as you so, deeply desire."
The other four students squirmed in their seats, not really eager to participate in the strange exercise. Eventually though, one of them, a slightly nerdy fellow by the name of Brian, spoke up. "I suppose, you could make him gain weight. Ruin his physique that he takes so much pride in."
"Oh, that would be good, wouldn't it Jimmy? Turn you into a fucking fat blimp?" Mr. Smith said, noting how hard Jimmy's cock had gotten at the suggestion.
"I...I mean, maybe, but not, like, forever, right?"
"Let's see how the pervert reacts as he grows to four hundred pounds of mostly fat over the next minute or so."
"Oh fuck," Jimmy said, his gut grumbling as it started to inflate. The rest of the class just gawked as Jimmy's muscular, toned physique was overwhelmed in a matter of seconds by pounds and pounds of fat. He'd begun at a trim 200 pounds. In thirty seconds, he passed 300, with a massive sagging gut, two heavy tits, and thickening thighs, and only continued to grow larger and larger, until he had a heavy apron hanging over his crotch, ham like arms, and three chins. "No...oh fuck..."
"Now, many perverts with a fetish for humiliating crave verbal abuse. I want each of your four to deliver a cutting insult to Jimmy, so we can observe his reaction. I'll demonstrate." Mr. Smith turned to Jimmy, and cleared his throat. "Look at you, you fucking lardass. We're going to have to change the mascot to a big fat hog at this point, and just let you run around naked on the field while everyone laughs at you during halftime."
Jimmy shuddered and moaned. There was the sound of something dripping below him, as his cock began to leak on the floor below, which only made him more horrified--and thrilled.
Mr. Smith turned to his students, indicating for them to go next.
Adam, another jock who had played around with Jimmy a few times before, said, "Fuck, I can't believe you're enjoying this. I'm going to tell everyone at school you fantasize about being a ugly fat pig."
Jimmy moaned and dribbled some more.
"Nicely done Adam. Not quite an insult, but the open threat of exposing his secret clearly hit the spot. How about you, Greg?"
Greg looked a little nervous, and stayed silent.
"You don't have to feel bad about it, Greg, the stupid fucking blimp will enjoy it. He can't help that he's a perverted freak who gets off on this fucked up shit. Go on Jimmy, encourage him."
Jimmy was panting a bit now. "Yeah Greg, fuck, tell me what you really fucking think of me, tell me how fucking disgusting I am."
"God, what the fuck is wrong with you?" Greg said, "You're fucking--I don't want to be involved in your weird fucking shit, just fucking leave me alone."
Jimmy moaned, and again, dribbles could be heard on the floor.
"Nicely done Greg. Social isolation and ostracization is often a fear held by men like Jimmy. The more people push him away, the more they enjoy it."
"I fucking meant it! This us fucked."
"Excellent Greg, truly. Next, Jonathan."
"You should probably just go roll around in mud and start squealing. You're a fucking hog, and everyone at school should know it. You should get even bigger, shovel all kinds of slop into your fat face."
"Another excellent example. The humiliation pervert craves encouragement. They are always looking for new ways to debase themselves, and though it might seem counterintuitive, they love positive reinforcement directed at their degradation. Finally, Brian."
Brian straightened up in his seat, a clear bulge in the front of his underwear under the desk. "You've made quite a mess on the floor their, you fucking pig. Get down there and clean it up with your tongue like the ugly, gross fucking pig you clearly want to be so badly. I'll take a video to send to your dad later."
Jimmy gave a little snort, and then did as he was told, dropping to all fours and licking his precum off the floor where he had dribbled it. Brian had his phone out, recording as promised. Mr. Smith beamed, "You four are naturals at humiliation. Demanding further degrading acts serves to reinforce his position, and the blackmail is a great touch. Now, do you think the pig has had enough?" Mr. Smith said, planting one foot on the back of Jimmy's head, and shoving him into the floor. "Trick question--of course he hasn't. Perverts like him become addicted to the thrill of humiliation, and are always looking for new ways to degrade themselves. Any further suggestions, class? I'm sure he'd love to hear them."
"You should lock the pervert's cock up," Greg said, "Make sure he can't actually have the satisfaction he wants."
"Yes, chastity is very popular with perverts like Jimmy. Stand up, you gross fucking pig, and show everyone your caged cock. I heard you had it permanently riveted shut--and haven't cum properly in over a year. You must be in a sexual haze all day long."
Jimmy stood up, precum smeared on his face, and hefted up his apron, showing off the very small cage around his cock. "Here's my worthless fucking pig cock," he said. "It's not worthy of cumming, or even pleasure."
"Tattoos and other body modifications would be good," Brian said, "The more visible the better."
"Sounds like you have a few in mind, Brian."
"Pig--no, the word 'Hog' across his forehead. And since his cock is worthless, why should he even have nuts at all? Why not castrate the fucking hog properly?"
"Oh? You are proud of all those filthy, horny tattoos aren't you, Jimmy?" Mr. Smith said, the class watching as all manner of humiliating pictures and words appeared all over his body. "But castration? Would you really go that far?"
Jimmy's eyes were wide, not quite sure how to answer.
"Forever making your status as something less than every real man you encounter, no longer capable of sexual satisfaction at all, fucking ruined. Is that what you want? You want me to take your fucking balls, you fucking bitch hog?"
"F-Fuck, I..."
"Beg me. Beg me to castrate you."
Jimmy dropped to his knees before his teacher. "Please Sir, please take my nuts. I don't deserve them, I don't want them. I want to be a nutless hog, ruined forever, and I want...I want everyone to know, everyone to know I'm nothing more than a disgusting castrated hog, eager for any man to use and abuse as he sees fit."
"So be it. You're nutless, if that's what you fucking want so badly."
Jimmy reached under his massive apron, found his caged cock, and...nothing else. No nuts at all, not even a scrotum, and he shuddered, desperately wanting to cum, but knowing he'd never have the satisfaction again.
Mr. Smith turned to Brian, who was groping himself in his seat. "You're clearly enjoying this, Brian. I think you have quite a strong desire to humiliate men, isn't that right? Why don't you come up here too."
"Now, turnabout is only fair play. You've had a big hand in taking Jimmy down from his handsome, muscular cheerleader life and reducing him to a nutless pig slave craving abuse. Every slave needs a Master, though. I think Jimmy should get to decide what kind of Master he'd like to have. So Jimmy, what kind of abusive freak would you like to see Brian here turn into?"
Jimmy looked up from where he was on his knees, eyes full of lust. "I want Brian to become..."
