"The Demons' Harem"
Contains: Prison dynamics, bullying, chastity, electric shocks, characters having their manly pride destroyed and being trained to become submissive sluts

A group of people somehow wound up as pets for a group of demonic friends. Maybe they were abducted, maybe they were tried and sentenced to this. They're men of all shapes and sizes, and some boys too. Some are chubby, some are muscular, some are scrawny, some are inbetween. Their demonic wardens wield power on another magnitude, so rebelling and escaping is impossible. They're punished for misbehaving, but the demons aren't omniscient and they tend to bully each other when they aren't being watched. The younger pets are left alone if they don't start trouble, by both the demons and the other prisoners. It's pity. The demons have warned them that if they are exceptionally bad, they will be forced to wear a chastity cage that can shock their genitals on command for pain or pleasure, and they will be actively trained for obedience.

One of the pets, a Pervert who is kinda into this kinda thing, is curious about this chastity cage. He finds an opportunity where he isn't being watched. Maybe it's the middle of the night, maybe everyone else is just distracted. He sneaks around and finds the chastity cage, and with his judgement clouded by lust, Pervert tries on the cage. Pervert panics when he realizes that the thing has been locked and he can't take it off. The demons eventually find him struggling with the cage, and decide that his punishment for being naughty will be to wear the cage forever, since he "likes it so much". The other pets are also aware of what transpired, and now Pervert has dropped to the bottom of their social ladder. He is regularly bullied by the other pets. They sometimes assault him and attack his balls since he "likes having his balls hurt". The demons are also taking him aside and subjecting him to subby training. It's completely degrading, being gang-raped and punished for daring to fight back, but compared to what the other pets do to him, it's a much much better treatment. At least they're gentle with him, and give him lots of affection throughout. The demons don't hold petty grudges and reward him generously for behaving, even though he was putting up such an ugly fight only recently. They're also really good at anally fucking him. Having gotten used to his penis being compressed, he doesn't feel the need to have it removed in order to satisfy his libido. Just leave everything to his demonic masters. They'll take care of him.

One day, the demons have all the pets stand in a line, and Pervert is brought up front to stand with them. Nobody is sure what's going on. Then the announcement is made: Pervert gets to choose somebody to join him in chastity. All the pets instantly turn pale with fear and Pervert himself takes an entire moment to fully comprehend the situation. Pervert surveys the lineup of potential victims, the ones that have tormented him so much that he desired the company of the demons more than anything else. He sees his worst Bully, the one who regularly kicked him in the balls and said such awful things to him. They make eye contact and Bully realizes that he is completely fucked. Pervert names Bully as the one who will join him. Bully tries to run, the demons grab him and restrain him. Bully screams bloody murder as a demon approaches him with Bully's very own chastity cage. Pervert watches this all go down and has this empty look in his eyes and a disturbing smile on his face. Not only are his curses for Bully being realized, but he feels so much relief now that Bully can't hurt him anymore. 

The deed is done, Bully's penis is locked up in metal for everyone to see. Bully is crying, and in a fit of rage, lunges at Pervert. A quick and decisive shock to the balls sends him to the floor instead. The other pets that used to laugh at Pervert for being the demons' bitch aren't laughing anymore. They see what happened to Bully and they feel nothing but fear, despair, and just a little bit of guilt for what they did to Pervert. Bully now joins Pervert in his training sessions. Bully isn't as quick to fold as Pervert was, but they're making progress. Bully now freely submits on command and doesn't attack Pervert anymore, but they haven't gotten him to accept that he feels pleasure from submitting... not yet, at least.

Life continues for some time. Bully has become something vaguely resembling a tsundere. The demons regularly force Bully and Pervert to hug and kiss and cuddle with each other. They don't have a choice because the demons literally have them by the balls. Bully swallows his pride and Pervert swallows his grudges. One day, the demons line everyone up again, and have Pervert stand in front of them with the demons again. "It's not happening again, is it?" is what's going on in everyone's minds. Sure enough, Pervert is asked to select someone who will join him and Bully in the chastity club. Pervert takes a moment to painfully recall the days when everybody wouldn't stop hurting him, and makes his selection. More running, more screaming, etc, etc. Now everyone is aware of the pattern that has been created, but they don't want to acknowledge it. One by one, Pervert will be given the privalege to condemn one of them to having their manhood locked up and weaponized against them, followed by a life of having their precious manly masculinity slowly ripped off of them, just like Pervert and Bully. They desperately try to appease Pervert, some of them threaten him instead, but Pervert is completely apathetic to their pleas. Aside from the children and the few that seemed to pity him during the dark days, Pervert just wants to see them suffer. Weeks go by, one by one everyone joins the chastity club.

Eventually, only a few people remain uncaged. The familar lineup happens again, but Pervert doesn't really wish to see them suffer, and acknowledges that it would be really petty to condemn the people that haven't done anything to hurt him. Even if they did nothing to save him from the likes of Bully, they probably didn't have the courage. Pervert names nobody as the next victim. To his shock and the utter despair of those remaining, the demons announce to him out loud that if he doesn't make a selection, then the demons themselves will make the choice. This begins a new age of pity for those on death row. The veteran chastity'd lads pity those that haven't adjusted to life as one of them, so they regularly help them out. The ones that were recently caged get rimjobs and prostate massages, and the ones that have yet to be caged get pity sex. Both of these groups are also given lots of TLC and reassurence that having your penis locked up isn't as bad as it sounds. There's no more bullying and flaunting of masculinity. It's just so petty, and everyone knows that now. Bully has long shed his aggressive and defensive attitude and he and Pervert have become best friends.

Now the final question is: Was this harem of chastity males the demons' original design, or was it just a chain reaction caused by Pervert's lust for being in chastity himself?
