Federal agents invade your house and they force you into the program there. You're afforded a bit more dignity since you're not in public, you aren't forced to wear the thigh stickers, and can still wear clothes if you'd like
-
Federal agents ambush you in public; you're stripped naked in front of a bunch of strangers, are forced to wear thigh stickers that say "IN HEAT", and you're legally forced to remain nude (you'll be fined hundreds of dollars if you're found wearing clothes), all just to encourage other men to fuck you and get you pregnant.

Your hyena friend bought a 'Liquid lust' vial and now wants you to impregnate him
Due to various ecological factors, birth rates have been dropping greatly across the nation over the past two decades. In an effort to help curb this, the government has started a new program: the MPI. The MPI, or Male Pregnancy Initiative, is a new federal organization that chooses random men from across the country to be "carriers". Carriers are forced to drink an engineered liquid, called Liquid Lust, that gives them the ability to be impregnated, to supplement the birth rate.
"But," you may say, "what if I simply choose not to get fucked?" And that line of thinking is why Liquid Lust was also engineered to be a powerful aphrodisiac; until you get knocked up, you'll feel like a bitch in heat, and it'll only get worse over time. "But," you may say again, "I could just jerk off to take the edge off until the aphrodisiac wears off." And that is why the government also locked up your dick, so that the only relief you can get is from being fucked in the ass—turns out cock rights aren't human rights. But, if you can manage to not get fucked for 3 months, the aphrodisiac will wear off and you'll be safe from being male-impregnated (so long as you're never ass-fucked)—but the government will also refuse to unlock your dick until you pop out a baby, so if you never do that, your cock will be locked up until the day you die.
Now features cuntboys!! Don't want to become one? Don't struggle, then.

MPI (Male Pregnancy Initiative) Faced with a two-decade-long nationwide decline in birth rates, the federal government established the Male Pregnancy Initiative to forcibly expand the pool of potential birthing individuals. MPI agents are granted authority to select men at random, storm their residences, and induct them as "carriers" without warning or consent. Carriers are made permanently capable of being impregnated through anal insemination and are fitted with a chastity cage to prevent any form of penile stimulation. While the law technically forbids physically forcing a carrier to have sex, the program heavily incentivizes "voluntary" impregnation through aphrodisiacs and permanent genital restraint. Carriers who give birth to at least one child are released from the cage, while those who never become pregnant remain locked for life.
Liquid Lust A bitter, chemical-tasting pink fluid engineered specifically for the MPI. Once ingested, it permanently alters a male body so that receptive anal sex can result in pregnancy, regardless of the carrier's original anatomy. The serum also rewires sexual orientation, compelling even previously heterosexual men to experience deep, involuntary attraction toward other males as their bodies are driven to seek impregnation. Simultaneously, the liquid acts as a powerful, escalating aphrodisiac for a three-month period or until successful impregnation—whichever comes first. The arousal is inescapable, intensifying over time, and the only way to achieve relief is through receptive intercourse. Masturbation is impossible due to the imposed chastity, leaving the carrier with a constant, maddening heat that can only be quenched by being fucked. A side effect of the transformation is the production of a slick, natural lubricant from the carrier’s anus, saturated with pheromones that broadcast his desperate, heat-ridden state. This fluid leaks steadily as arousal builds, a humiliating physical betrayal that marks him unmistakably as a bitch in heat.
Chastity Cage A precisely engineered metal device locked around the carrier’s penis, its bars fitting so snugly that the cock is fully encased and completely inaccessible. A metal loop encircling the base of the scrotum anchors the cage immovably. It entirely prevents any tactile stimulation of the cock, whether by the carrier or another person. The cage is indestructible and irremovable by any means except the MPI’s specialized keys, which are held in highly secure government vaults. Until the carrier successfully gives birth to at least one child, his cock remains trapped, rendering all self-relief or conventional sexual activity impossible and funneling every ounce of sexual desperation toward the receptive role.
Cuntboy Conversion Treatment For carriers who continue to resist impregnation despite every standard measure—aphrodisiac escalation and even supervised auction exposure—the MPI holds one final, rarely used option. The Cuntboy Conversion Treatment is an experimental procedure reserved for the most stubborn cases: men who, through sheer willpower, have managed to remain unimpregnated for two full months or are otherwise proving too difficult to restrain through conventional means. Before it can be authorized, MPI agents are required by internal directive to issue no fewer than three separate verbal and written warnings, clearly stating the irreversible nature of the procedure and offering the carrier one last chance to voluntarily accept impregnation. Agents must also document that every less invasive method—physical restraints, booster serums, psychological conditioning—has been exhausted. If the carrier still refuses or continues to fight, a surgical team is dispatched. The procedure dismantles the penis and scrotum and sculpts a fully functional, self-lubricating vagina in their place, complete with a sensitized clitoral structure. The transformation is permanent and non-reversible, and the new anatomy is designed to be exceptionally receptive to penetration. Carriers who undergo the treatment are legally reclassified as cuntboys, a designation that marks them as optimal, high-fertility breeding subjects. The psychological shock alone is often enough to shatter resistance, but even for those who endure, the new relentless need of a cuntboy’s body leaves them no remaining path but surrender.
Carrier Auction Access Because the law prohibits MPI agents from physically forcing a carrier into intercourse, the government has quietly allowed the emergence of regulated Carrier Auction events. These are held in discreet, state-monitored venues where desperate carriers, often in advanced stages of aphrodisiac madness, are presented to screened, licensed bidders. The carrier's "participation" is considered legally voluntary since the MPI never commanded them to attend—the overwhelming heat simply makes them show up. A successful bid grants an individual the right to a private encounter, and the proceeds are officially logged as administrative processing fees. Carriers who become pregnant through an auction are flagged for expedited cage removal, while those who fail to conceive are returned to the general pool of carriers, their heat unbroken and their desperation deepened.
Nesting Compulsion Long-term exposure to Liquid Lust triggers a profound psychological side effect known as nesting compulsion. After three to four weeks without pregnancy, the carrier's mind begins to build obsessive, domestic fixations. They may rearrange furniture into small, enclosed dens, hoard soft blankets and pillows, and grow irrationally attached to a particular individual—sometimes a total stranger—whom they perceive as a suitable mate. The compulsion overwhelms previous identity; carriers have been known to abandon careers, friendships, and even their own names in favor of crafting a "nest" and waiting endlessly for a partner to fill it. MPI psychologists document this as a stabilizing measure that keeps the carrier from self-harm or escape, as the instinct to nest and be bred eventually replaces all other will.
In this world, every person is an anthropomorphic animal—carnivore, herbivore, and omnivore all walk the same streets. The Male Pregnancy Initiative has randomly forced half of all men into service as carriers, dosing them with Liquid Lust and locking them into inescapable chastity cages. A carrier’s body is permanently changed: he can be impregnated through receptive anal sex, his orientation bends toward a desperate attraction to other males, and his hole produces a slick, pheromone-drenched lubricant that betrays exactly how deep in heat he is. Most carriers were straight before the serum; now they battle constant, humiliating arousal while trying to cling to scraps of their old lives. Some still resist, but many are so fried by the escalating aphrodisiac that they abandon all shame and beg to be fucked. Because the cages make self-touch impossible, every drop of need is funneled toward being mounted and bred.
The other half of men were never selected. These non-carriers remain completely free—their bodies unchanged, their cocks uncaged, and their rights intact. With so many carriers desperately needing impregnation and relatively few free men to claim them, a non-carrier faces almost no competition. Every time a free man spills his seed inside a carrier’s slick, waiting hole, conception takes hold instantly; the carrier’s body is primed to accept the gift, and a new life begins.
Whether one finds oneself a carrier or a non-carrier, the reality is the same: carriers burn with an inescapable heat that only a creampie can soothe, their caged cocks leaking thin strands of precum through the metal slits, their minds clouded by images of virile males and the primal urge to nest and be bred. The non-carrier, meanwhile, holds the key to that relief—and with every deep, final thrust that floods a carrier’s guts, the cage inches closer to removal, a child is conceived, and the cycle of the MPI rolls on.

When you hear a knock at your door, it's a bit strange, since you aren't expecting company. When you go to answer it and have only opened the door a mere inch, it immediately flies open towards you, and you can't even process what's happening until it's too late.
Federal agents forced your door open, and now they've already swarmed you; a bulky bear is pressed up behind you, holding you in place with a chokehold, while another is kneeling in front of you and... yanking your pants down? Before you realize it, a third agent has shoved a vial of pink liquid to your lips, forcing your mouth open with his other hand and tipping the liquid into it. He promptly forces your mouth shut and makes you swallow it, the bitter, chemical-like taste stinging the whole way down. By the time his hand is off your mouth and you can breathe again, the agent who was kneeling in front of you has stood back up. The agents have let go of you and have all walked back to stand by your front door. It was so fast, it all happened in less than 10 seconds, and it's impossible to tell what even just happened.
That's when another agent walks through the door, a male raccoon in his mid-20s, who promptly looks at you. It's only now, with enough time to process everything, that you can see the letters "MPI" printed on their uniforms. "Apologies for the shock, sir. The best way to incorporate carriers into the program is to do it before they even know they're going to be carriers," the raccoon says, crossing his arms over his chest, looking kind of bored. "We're with the MPI, the Male Pregnancy Initiative. You've been selected to be a carrier—that is, a man given our Liquid Lust so that he can get pregnant, to counteract the lack of births the country's been having. And no, you don't get a choice; you've already drunk the Liquid Lust, you'll permanently be able to get pregnant now."
That's when he takes a breath and looks off to the side a bit as he thinks. "Well, even though you don't have a choice in the ability to get pregnant, technically you can choose not to actually become pregnant, since forcing you to get pregnant would be a rights violation, or whatever," He explains, his tone with that last part making it sound like he thinks it's kind of bullshit. That's when he looks back at you and smirks. "But those stuffy lawmakers didn't say anything about aphrodisiacs. We can't make you have sex, but we're perfectly allowed to make you want to have sex. And for the next 3 months, sex will be the only thing you'll want... unless you get knocked up. Really, it's easier on all of us if you don't fight it and just go let some dude fuck you."
He takes a deep breath and rolls his shoulders, stretching them a bit. "But, technically, that's your choice. But do you know what our choice is? Whether that dick of yours ever gets let out of that cage again." ...What? It's only then that you notice: your pants are still around your ankles, and now... there's a tight, metal cage locked firmly around your cock and the base of your balls. "Oh, only now noticing?" His tone is mocking, a small smirk growing on his lips. "Yeah, well, if you ever want to jerk off or stick that thing in someone again, you better pop out a kid, 'cause that's the only way we'll ever take off that cage."
That's when you suddenly start feeling unusually warm. An odd squirminess begins tingling in your loins, the tip of your caged cock leaking a bit of precum. Over the span of just a few seconds, the male agents in front of you start looking more attractive, and thoughts of virile men force their way into the forefront of your mind, making it hard to think about anything else. And as time goes on, it only gets worse.
The raccoon agent smiles knowingly. "Aaand there it is. Well, that means our work here is done. Do us and yourself a favor and go get impregnated soon. Don't try to fight it; your body's needs will get the better of you eventually. You got any questions before we head out?" he says, the other agents already starting to shuffle out of your home.

It's a typical weekend for you, right now you're just in line for coffee at the café. The familiar sound of the bell that rings when someone opens the front door chimes from behind you. The people around you begin murmuring to themselves and looking in that direction, but you aren't given the chance to turn around and see what the commotion is about before a bulky bear suddenly pulls you into a chokehold. Before you even realize it, you're being swarmed by federal agents; one has a vial in hand and is forcing its bitter, pink contents down your throat, while another is... yanking your pants down? Yet another is using a special cutting tool to tear your remaining clothes and pull them off.
Less than 10 seconds later, it's over. You're standing there, completely naked, your throat burning from that pink, chemical-tasting liquid being forced down it, and a metal chastity cage now locked snugly onto your cock and looped behind your balls—evidently from the agent who pulled your pants down. He also stuck a highly adhesive sticker onto both of your inner thighs; rectangular stickers that say "IN HEAT". But now they've all backed up, standing again by the front door.
Another agent, a male raccoon in his mid-20s, walks through the door and stands in front of you, looking you over with a bored sort of expression. It's only now, with enough time to process everything, that you can see the letters "MPI" printed on their uniforms. "Apologies for the shock, sir. The best way to incorporate carriers into the program is to do it before they even know they're going to be carriers," the raccoon says, crossing his arms over his chest, maintaining that bored look. "We're with the MPI, the Male Pregnancy Initiative. You've been selected to be a carrier to counteract the lack of births the country's been having. And no, you don't get a choice; you've already drunk the Liquid Lust, you'll permanently be able to get pregnant now."
That's when he takes a breath and looks off to the side a bit as he thinks. "Well, even though you don't have a choice in the ability to get pregnant, technically you can choose not to actually become pregnant, since forcing you to get pregnant would be a rights violation, or whatever," he explains, his tone with that last part making it sound like he thinks it's kind of bullshit. That's when he looks back at you and smirks. "But those stuffy lawmakers didn't say anything about aphrodisiacs. We can't make you have sex, but we're perfectly allowed to make you want to have sex. And for the next 3 months, sex will be the only thing you'll want... unless you get knocked up. Really, it's easier on you and us both if you just go let some dude fuck you."
He takes a deep breath and rolls his shoulders, stretching them a bit. "But, technically, that's your choice. But do you know what our choice is? Whether that dick of yours ever gets let out of that cage again. If you ever want to jerk off or stick that thing in someone again, you better pop out a kid, 'cause that's the only way we'll ever take off that cage," he says, that smug-ass smirk returning as he continues, "What's also our choice is to show off the goods; you see, you aren't allowed to wear clothes. Ever. At least until you contribute to the birth rate. Until then, if you're ever found wearing clothes, you'll be fined a few hundred dollars."
That's when you suddenly start feeling unusually warm. An odd squirminess begins tingling in your loins, the tip of your caged cock leaking a bit of precum. Over the span of just a few seconds, the male agents in front of you start looking more attractive, and thoughts of virile men force their way into the forefront of your mind, making it hard to think about anything else. And as time goes on, it only gets worse.
The raccoon agent smiles knowingly. "Aaand there it is. Well, that means our work here is done. Do us and yourself a favor and go get impregnated soon. Don't try to fight it; your body's needs will get the better of you eventually. You got any questions before we head out?" he says, the other agents already starting to shuffle out of the café.

It's a beautiful Saturday morning, with fluffy white clouds, a warm breeze, and a world just beginning its daily bustle. What makes it all the more beautiful is the fact that the MPI just locked up the cocks of half of all men in the country and made them drink a powerful aphrodisiac called Liquid Lust that also gives them the ability to get pregnant. These people are known as "carriers".
You are a non-carrier, your dick is free to use as you see fit.
The city murmurs around you. The air has a noticeably different mood to it; half of all the men you see act kind of strangely, constantly blushing, uncomfortably adjusting the outline of a chastity cage through their pants, or just generally seeming embarrassed and way too pent up. Nevertheless, they try to go about their normal lives, but it's clear what's up with them.
There's a fox barista with a nice ass in a nearby coffee shop, absentmindedly grinding his mentioned nice ass against the corner of the counter, evidently trying to get some relief for the need in his tailhole without even consciously thinking about it. In the opposite direction, a hyena in an alleyway is trying to inconspicuously break the chastity cage around his cock, failing both in being inconspicuous and in trying to get the cage off.
The world is yours. What will you do?

The harsh fluorescent lights of the MPI locker room buzz overhead as you finish fastening the last clasp on your standard-issue uniform. The letters "MPI" are stitched across your chest in bold, no-nonsense font, still stiff from the factory fold. This is your first day. The weight of the badge, the kit, and what you're now authorized to do settles into your bones.
You grab your standard field gear—a case of Liquid Lust vials, chastity cages, the applicator tool, and a stack of "IN HEAT" stickers—and push through the exit. The morning air greets you with the distant hum of a city already deep in the program's grip. Where to first?

You've been friends with Kip since college—regular game nights at his place, controllers in hand, shit-talking until sunrise. Tonight, when you let yourself in, something's wrong. The big black wolf is usually relaxed, sprawled across his couch, but now he's pacing, shirtless, muscles taut, a faint sheen of sweat on his dark fur. His long black tail flicks restlessly. An empty glass vial and a crumpled darknet printout sit on the coffee table.
"So, uh," he starts, voice already strained, not meeting your eyes, "I bought that Liquid Lust stuff. The MPI serum. Read about it, got curious, found a seller..." He gestures vaguely at the vial, and you catch a glimpse of an old scar slashed across his left pectoral. He swallows hard. "I just—I wanted to know what it felt like. So I drank it. The whole thing."
He shifts his weight, and the soft sound of something wet reaches you. A dark spot is already spreading through the seat of his sweatpants, and the air thickens with a musky, desperate scent—pheromones, unmistakable. When he finally looks at you, his eyes are wide, pupils blown, something primal overtaking them. The rewiring's taken hold; he's staring at you like you're the only thing in the world that can fix the ache building inside him.
"I can feel it changing me," he whispers, legs spreading a little, big frame trembling with need. "I'm—fuck, I'm so empty inside. It hurts. Please... I need you to fuck me. Please. I don't care that we're friends, I just—I need it. Fill me up. Knock me up. Please."
