Yes

The S-Bahn rocked gently as it pulled out of München Ost. Rain on the window, the city dissolving into impressionist smears -- concrete, copper facades, a flash of neon from a Späti still open despite the hour. Rammstein in his earbuds. "Mein Herz Brennt." My heart burns. His surname meant the same: Brenner, the burner. But nothing about Lukas Brenner was on fire.

Twenty-eight years old. Three hoodies in rotation. Twenty-two months since he'd last had sex. Not that he was counting.

He was counting.

The train passed Trudering, Gronsdorf, Vaterstetten. The apartment blocks thinned. Fields appeared between houses, dark in the early evening, barely visible through the rain. In summer you could see the Alps from here -- a jagged white line above the foothills like a border drawn in chalk. Tonight there was only fog and the smell of wet earth seeping through the ventilation.

He thought about what Linh had said. Writing data INTO users. Into the biometric layer. Into their bodies.

He thought about Viktor's eyes not matching his mouth.

He opened the Pleroma app and looked at the welcome gift notification.

PLEROMA: Welcome gift available. Choose one free transformation from the Tier 1 menu. This is our gift to you -- experience the future.

The train pulled into Grafing Bahnhof. He stepped out into the rain.

Grafing bei München. A small town in the Voralpenland -- the foothills before the Alps. Population twenty-two thousand. The kind of town where the baker knew your order and the butcher knew your name and the church bells rang at seven whether you liked it or not.

His apartment was five minutes from the station. Second floor of a pale yellow building, built in the seventies, unremarkable in every way except that the balcony faced south and on clear mornings you could see the Wendelstein. He'd moved here after Jana left. Two years ago. Sometimes it felt like two months. Sometimes like twenty.

The stairwell smelled like the Müllers' Schweinebraten -- caraway and roasting pork, drifting up from the first floor. A good smell. A normal smell. Herr Müller separated his recycling with military precision and once lectured a delivery driver about the Gelber Sack protocol for fifteen minutes. In Bavaria, order was not a preference. It was a religion.

Lukas's apartment was the opposite of order. Dirty coffee cup on the desk. Running shoes by the door, unused for weeks. IKEA furniture in the same oak-effect that said "I have given up." A Post-it on the fridge in his own handwriting: "Call Mama." Three days old.

He opened the fridge. Leberkäs from Metzgerei Brandner, two days old. Old Herr Brandner still made it by hand, wrapped it in wax paper, said "Pfiat di" instead of "Tschüss." A bottle of Augustiner Helles. Half a cucumber going soft.

He heated the Leberkäs. Forty-five seconds -- Brandner's rule, any longer and it goes rubbery. Sliced it onto Schwarzbrot. Added Senf. Opened the beer.

He sat at his desk and ate in the silence of his apartment. The pressurized silence of a room where only one person breathes. The Zugspitze poster Jana had bought at a Giesing flea market stared at him from the wall. He'd never taken it down because the wall behind it had a stain.

The app glowed.

He thought about Linh's warning. Something is writing data into users. Into their bodies.

He thought about Viktor's hand on his shoulder, too strong.

He thought about twenty-two months.

He tapped the skill tree.

SEX. CONTROL. BODY. OTHERS.

He tapped SEX.

Two options: Balls I. Cock I.

Cock I: "Your cock gets 20% bigger. 50% bigger when flaccid. Enhanced sensitivity. Reduced refractory period."

He read it twice. Took a drink of Augustiner. The beer was good. Honest, like everything in Grafing. Like the Leberkäs and the church bells and the fog in the valley.

PLEROMA: Confirm transformation? This action cannot be undone.

His thumb hovered.

Don't go through Viktor, Linh had said. Something is writing to their bodies.

He pressed Confirm.

Which brought him here. To his bathroom. To the fluorescent light. To the fact of his changed body.

The warmth had started in his belly -- low and spreading, like the first sip of Glühwein on a December night. It radiated downward through his pelvis, into his groin, and then it stopped being warmth and became something else. Movement. Something rearranging itself beneath the skin.

He'd gripped the edge of his desk. His jeans tightened. Not metaphorically -- the denim actually strained against his crotch, and he heard the seam creak, and he stood up so fast his chair rolled into the wall.

In the bathroom, he'd pulled down his jeans and watched.

It happened over maybe ninety seconds. His cock thickened first -- the shaft swelling, the skin stretching taut, flushed with blood that wasn't just arousal. This was structural. Tissue growing, expanding, the veins standing out in sharper relief. Then it lengthened. Not dramatically -- he wasn't watching himself become a monster -- but enough. Enough that the weight of it pulled differently when it hung. Enough that when it brushed the inside of his thigh, the sensation made him gasp.

The sensitivity was the worst part. Or the best part. He couldn't decide. Every nerve ending had been recalibrated. The cool air of the bathroom on his bare skin felt like a hand. The fabric of his boxers, when he'd pulled them back up, was almost unbearable against the head -- a friction that was half-pain, half-pleasure, relentless.

He was hard. Completely, achingly hard, without having thought a single sexual thought. His new cock stood against his belly, flushed and heavy, and it didn't feel like his. It felt like someone else's cock had been grafted onto his body. Same shape, same mole on the left side of the shaft, same slight leftward curve -- but MORE. Like a photograph that had been retouched to be slightly too vivid.

And underneath it all, beneath the physical changes, something else. A low hum in his pelvis. Not a sound -- a sensation. A vibration, like the idling of an engine he couldn't turn off. The nanobots, he realized. Whatever they were, they were still in him. Still working. Still writing.

His phone buzzed on the sink.

PLEROMA: Transformation complete. Cock I active. Enjoy your new reality.

Below the notification, the matching screen had activated. He hadn't opened it. Hadn't asked for it. But the app had surfaced it anyway: a grid of faces, filtered by proximity, sorted by a metric he'd coded himself but suddenly didn't trust.

And there, twelve meters away, blinking online:

MAREN HOFSTETTER. 34. 12 meters away.

A chat bubble appeared before he could close the screen.

MAREN: Hey neighbor :) I see you're on here too

Twelve meters. Across the hall. The woman who'd lent him eggs and returned Kaiserschmarrn. The divorcée with the Pilates body and the red Fiat 500 and the son who left glow-in-the-dark stars on the ceiling.

His new cock throbbed. The hum in his pelvis deepened. And the app -- he was sure of this, it wasn't a glitch, it wasn't a feature he'd built -- the app pulsed brighter when he looked at her profile photo. As if it were encouraging him.

As if it knew.
