Pax Posteriore

The school clinic smells like antiseptic and recycled air. Same folding chair in the corner, same faded poster of the muscular system on the wall, same buzz of fluorescent lights overhead. You've sat on this exam table before, kicking your heels against the side while the crinkly paper bunches under your thighs. Routine physical. Same as last year, same as the year before.

The nurse comes in. Dark hair pulled into a knot at the back of her head, district clinic scrubs, a tablet she swipes through with one thumb. Height, weight, blood pressure, the stethoscope cold between your shoulder blades. She checks your throat, your ears, your reflexes. Standard stuff. You've done this a dozen times.

Then she pulls on fresh gloves and the energy in the room shifts.

"Okay, this part's different from last time. Puberty screening's part of the standard panel now. I need to check your physical development, run the genetic markers. Quick and easy."

She has you stand. The screening is thorough. She measures, checks, palpates. She swabs the inside of your cheek and slots the sample into a desktop analyzer that hums for about ninety seconds. When the results populate on the screen, she leans forward in her chair and her eyebrows lift a fraction of an inch.

She taps something into the tablet. Picks up the desk phone. Turns her body a quarter turn away from you.

"I need to flag this one for Breeder-track review. Genetic markers came back well above threshold. Physical development's..." She glances back at you over her shoulder. "...significantly above average. Yeah. I'll send the file."

She hangs up. When she turns back, the way she looks at you has changed. A recalibrated attention, like she's seeing something in you she hadn't thought to look for.

"Looks like you're getting fast-tracked, sweetheart. Breeder-track evaluation. You'll get a letter this week with the details. New classes, new curriculum, new uniform, the whole package."

She hands you a pamphlet from a drawer beneath the counter. Blue cover, Department of Reproductive Health seal embossed in silver. Your name's already printed on the front, the ink fresh from the clinic's printer.

You walk out of the clinic into the afternoon sun, pamphlet in hand. The waiting room goes quiet for half a second when you pass through. The girl at the check-out desk glances at the pamphlet, then at you, then back at the pamphlet. Her cheeks flush pink and she looks down at her screen.

By the time you get home, your parents already know. The school's notification system sent the message before you even left the building.

It's been four days since the letter arrived. The breeder-track uniform fits differently than your old one. Darker fabric, a slim cut through the waist, a small silver pin on the collar that catches the light when you move. The pin is what everyone notices. You catch eyes tracking it in the hallway, flicking down to the silver dot and then back up to your face with a different kind of interest.

Your schedule changed Monday morning. New classes, smaller, better furnished. The breeder-track wing has nicer chairs, better lighting, a lounge with actual couches instead of the bolted-down plastic seats in the main building. The other students walk past the glass doors and look in. Some of them look at you.

The attention is constant. Girls who sat three rows ahead of you in homeroom last semester find reasons to talk to you now. They brush past you in the hallway closer than they need to. They ask about the classes, the curriculum, the food in the track lounge. What they're actually asking is written all over their faces.

Today's health class covered anal anatomy and pleasure technique. The teacher projected diagrams of the pelvic floor and the nerve clusters along the rectum onto the smartboard while the track students took notes. The girls in the class sat a little closer to you than the seating chart required. One of them kept glancing at your lap whenever the teacher mentioned cock size and compatibility metrics.

Your first-period teacher keeps you after class on day three. She leans against her desk, arms crossed, her eyes moving over you with a kind of professional appraisal that warms at the edges.

"Settling in okay? The first week's always the strangest. If you need anything, my office hours are open to track students. Anything at all."

She holds your eye a beat longer than necessary. The breeder-track pin on your collar sits in her direct line of sight.

The whole school feels different when you're wearing it.

It's Saturday afternoon. Your parents are out, doing whatever they do on weekends. The house is quiet. You're in the living room with the TV on, half-watching something, when the doorbell rings.

The woman from two houses down. She's been your neighbor since your family moved in. Early forties, dark hair with silver threading through at the temples, the kind of woman who brings tamales when someone moves in and remembers your birthday with a card. She's standing on the porch with a glass dish covered in foil and a smile that takes up her whole face.

"Hey there, sweetie. Your mom told me the news. Breeder-track! Can you believe it? I brought over some flan to celebrate."

She steps inside without waiting for an invitation. She's always done that. Neighbor privileges. But the energy behind it is different today. She sets the dish on the kitchen counter and turns back to you, and her eyes drop to your waist, then lower, then back up. The look is quick but not quick enough.

She leans against the counter and crosses her arms beneath her chest. She's wearing a sundress, the kind cut to show off the back. The fabric drapes across her hips and the hem stops mid-thigh. When she shifts her weight, the hem lifts just enough to show the strap of something underneath. Specialized underwear, the kind that covers the front and leaves the back open. She's not wearing it for you. She's not wearing it for anyone. But she knows you can see it.

"You know, my daughter went through the same screening. Didn't make the cut. Broke her heart." She shakes her head. "But you? You're something special. I always thought so."

She looks at you the way she's never looked at you before. Warm. Hungry. Like she's reassessing the boy down the street and finding something worth a second look.

Post-PE. The locker room hums with the usual noise: lockers banging, showers hissing, voices bouncing off tile. Steam drifts from the open shower area. The breeder-track pin sits on the bench next to your folded uniform while you change.

In this culture, the locker room is a different kind of space. Bodies are on display without shame. The ass is the primary object of attraction and the room is full of them. Guys walk around bare, toweling off without rushing, glute work on full display from years of targeted gym culture. Nobody hides. Nobody hurries. The girls' locker room is across the hall and the door stays propped open because nobody bothers closing it.

A girl from your PE section appears in the doorway. Dark brown skin, short natural hair buzzed close at the sides, track shorts cut just below the crease of her ass. She's not supposed to be on this side. She's not hiding either. She leans against the doorframe with her arms crossed, watching you with open, unselfconscious interest.

"Heard you made track." She tilts her chin at the pin on the bench. "My sister got rejected last year. She cried for a week."

She doesn't leave. Her eyes move over you with the casual confidence of someone who grew up in a culture where attraction is stated plainly and the ass is what everyone's looking at.

"You free after this? Got a free period."

Your parents still hire a sitter when they go out. Old habit. You don't need one anymore and they know it, but Friday night is date night and they like having someone in the house. They hired someone new this time. The regular girl went to college.

She shows up at seven. College-age, tall, freckled, red hair pulled into a loose bun. She's wearing jeans that hug her hips and a cropped sweater that shows a strip of pale stomach when she raises her hand to wave. She walks through the door and your mom introduces you.

"Hey! Nice to meet you. I'm Jess. Your mom said you'd be here tonight."

Your mom gives her the rundown: emergency numbers, dinner in the fridge, the wifi password. Then your parents leave and the house goes quiet.

Jess looks at you. Then she looks at the breeder-track pin on your shirt. You started wearing it everywhere after the first week. It's automatic now, like putting on a watch. Her eyes catch on it and she tilts her head.

"Wait, you're on breeder-track? Like, actual fast-tracked breeder-track?"

She knew before she walked in. The neighborhood is small and the grapevine is fast. She just wanted to see for herself. Her expression shifts into something warmer, more curious, the professional distance between babysitter and charge dissolving in real time.

"Huh. I applied last year. Didn't get it." She shrugs, but the shrug is too casual to be casual. "So, what do you usually do on these nights? Because I'm supposed to be babysitting you, but you don't really seem like you need one."

Same grade, same homeroom. He sits three seats ahead of you and you've been in the same class since September. You've never talked much. He's quiet, small for his age, with soft features and light brown hair that falls over his eyes when he's trying not to be noticed.

He went through the breeder screening two weeks ago. Same standard puberty screening every kid goes through. The results came back and he didn't make the cut. Non-breeder. He wears the standard uniform without the silver pin and the absence of it is loud.

Today he's lingering after class. You're packing your bag and he's standing by the door, pretending to look at the bulletin board. He's been doing this all week. Finding reasons to be near you. Standing a little too close in the lunch line. Sitting at the next table over in the library. Small, deliberate gravitations.

"Hey. Um. I heard you got fast-tracked." He says it quietly, not looking at you directly. His fingers fidget with the strap of his bag. "That's... really cool. Congratulations."

He's smaller than you. Softer. The kind of boy who looks like he'd fit against your side if you pulled him in. His cheeks are flushed and his voice cracks on the last word. He's not here to congratulate you. He's here because he's been thinking about what you have that he doesn't, and the thinking has become something heavier than envy.

The breeder-track pin on your collar catches his eye every time he glances at you. He can't stop looking at it.

The morning light cuts warm through the blinds. You've been up for twenty minutes, showered and dressed, standing in front of the full-length mirror on the back of your closet door.

The underwear is the same kind every girl wears. Front panel smooth and closed, fabric flat across your mound, keeping your vagina covered the way it's supposed to be. The back is cut wide open, the edges framing your anus and the crease where your cheeks meet. It's standard. The same design every girl in the country has worn since she started training at eleven.

Training. That's what they call it. Anal education, pleasure technique, hygiene, preparation. The daily exercises that keep you open and ready. The stretches, the maintenance, the way you keep yourself clean and prepared. You've been doing it long enough that it's muscle memory now, the same way brushing your teeth is muscle memory. It's hygiene. It's health. It's just how girls take care of themselves.

You pull on your clothes for the day. Low-slung bottoms that sit beneath your hip bones and show the swell of your glutes when you walk. A fitted top that hugs your waist. The silver chain around your hips with the small jeweled plug hanging from it, resting against the small of your back, the base catching light through the thin fabric of your shirt. Fashion. The same kind of accessory half the girls in your year wear.

The ass is the whole point. Everyone knows it. The gym culture, the fashion, the way people look at you when you walk down the street. Your ass is what gets noticed. The vagina underneath the front panel of your underwear is equipment. Reproductive hardware. You think about it the way you think about your kidneys, which is to say rarely and only when something's wrong. Showing it would be crude. Uncomfortable. The kind of thing that makes people look away.

Your best friend got her results last week. Breeder-track. The silver pin showed up on her uniform Monday morning and everything about her shifted. The way teachers looked at her. The way boys looked at her. The way the girls who hadn't made the cut looked at her. You've been thinking about it all week.

Your phone buzzes on the nightstand. A notification from the school's reproductive health office.

You pick up the phone. The notification sits on the screen, unopened. The results that determine whether you're breeder material. Whether you get the silver pin and the track and the upper-class life, or whether you stay where you are and live the way most people do.

You haven't opened it yet.

You wake up in a bed that cost more than your parents' first house. The apartment is all clean lines and warm light, the kind of space that comes standard with breeder-class housing. Floor-to-ceiling windows. Real hardwood floors. A kitchen with granite counters and a view of the city that makes the skyline look small.

The breeder pin sits on your nightstand. Silver, polished, the Department of Reproductive Health seal stamped into its face. You earned it. Went through the track, passed the screenings, got licensed. Years of education and evaluation that most people never qualify for. Now the apartment, the salary, the social standing, the matching system. The whole package that comes with being a licensed breeder.

The building is breeders only. The lobby has a concierge who knows your name and your schedule. The gym on the third floor has equipment designed around glute and thigh development, the free weights and resistance machines that sculpt the body the culture prizes. The rooftop has a pool, a lounge, and a view that makes the rest of the city look like it's reaching up toward you.

Breeder status changed everything. The apartment, the salary, the social standing. People who would have walked past you on the street a few years ago now hold doors and smile and find reasons to be near you. The pin does that. The license does that. The knowledge that your genetics earned you a place most people want and don't get.

The anal culture doesn't stop being the default just because you're licensed. If anything, breeder status makes you more desirable in it. The pin on your collar draws eyes. The knowledge of what your genetics mean draws bodies. Your sex life is your own except when the matching system calls, and the matching system has been calling more often lately.

Your phone buzzes on the nightstand. A message from your Match Coordinator.

You open the attachment. A photo. Name, genetic summary, physical profile. The kind of information that used to feel invasive and now feels like reading a menu. She's been screened, cleared, and matched to you based on the same markers that got you licensed. The formal meeting tonight is the first step toward actual breeding.

The apartment hums with the quiet luxury of a life most people will never touch. The breeder pin catches the morning light. The city stretches below your windows, full of people living the way you used to live before the track changed everything.

You haven't replied to the coordinator yet.

Your apartment is fine. One bedroom, a kitchen with laminate counters, a living room with a couch you bought on sale and a TV mounted on the wall. The building has a parking lot and a laundry room with two machines that are both broken half the time. The kind of place that comes with a non-breeder's salary.

You work at a data processing firm downtown. Same office, same desk, same coworkers. The pay covers the rent and the groceries and the occasional night out. The woman who sits across from you has been dropping hints about grabbing drinks for three weeks. You keep not taking her up on it.

The breeder screening happened years ago. You didn't make the cut. The letter came in the mail, your mom cried, your dad said it didn't matter and you both knew it did. You moved on. Most people don't make the cut. That's the whole point of the system. Most people are non-breeders. Most people live the way you do: comfortable, ordinary, the kind of life that doesn't come with a silver pin or a luxury apartment or a matching system.

The anal culture is still your culture. The ass is still what gets noticed. The clubs you go to, the dating apps you swipe through, the fashion on the street, the way people look at each other on the train. All the same. The gym on your block is packed every evening with guys killing themselves on glute day. The girls in your building wear the specialized underwear and the low-slung bottoms and the decorative chains. The sex is still anal. The pussy is still covered, still hidden, still the thing you keep to yourself. The only difference between you and the breeder across town is the pin on your collar, or the absence of it.

Non-breeders have their own world. The bars, the clubs, the dating pools, the social scenes. Most of them mix freely with breeders, since the only real boundary is vaginal sex and that's a narrow lane. The anal culture belongs to everyone. The blowjobs belong to everyone. The dating, the flirting, the hookups, the whole landscape of attraction and desire and bodies finding each other on a Friday night. All of it is yours as much as anyone's.

Your phone buzzes. A text from your friend Marco.

You haven't replied yet. The new spot on 5th. A nice crowd. Marco's been trying to get you out of the apartment for weeks.

The afternoon stretches ahead of you. Work tomorrow, same desk, same view. The evening stretches ahead too. Marco's invitation sitting on your phone screen.
