The final bell rang through the school like a death knell.
Students poured out of the classrooms, laughing and chatting loudly as they headed home. I remained seated at my desk near the back, completely still. Through the window, the sun was sinking below the horizon, painting the sky in deep, blood-like shades of crimson. It looked unnatural today — too red, too heavy, as if the sky itself was infected by the same mark that now pulsed beneath my skin.
I waited until the hallways grew quiet. Until the last voices faded into the distance.
Only then did I stand up and leave the classroom.
My body felt heavy. Used. The mark on my neck throbbed with a slow, constant heat that refused to let me forget what I had done — what I had become.
I stopped at the bathroom first. The fluorescent lights buzzed overhead as I turned on the faucet and splashed cold water on my face. When I lifted my head and looked into the mirror, my stomach dropped.
The crimson mark had spread.
What started as a simple pattern on my neck now crawled upward like living veins. Intricate, ancient-looking branches spread across my left cheek and up to the corner of my left eye, forming a terrifyingly beautiful design — like a sacred tree from some forgotten civilization, twisting and blooming in dark red ink. Similar vein-like patterns had also spread down my right arm, visible beneath the rolled-up sleeve of my shirt.
I touched it with trembling fingers. It was warm. Almost hot.
Then I looked deeper into my own reflection.
It didn't feel like me anymore.
My eyes looked slightly darker. The pupils seemed too large, too still. For a split second, something behind my reflection shifted — a tall, thin silhouette with too many joints standing just over my shoulder. When I blinked, it was gone. But the unease remained.
I wasn't looking at Ren Amekawa anymore.
I was looking at something that was slowly becoming… other.
I quickly turned away from the mirror and left the bathroom, heart pounding. The crimson sunset bathed the empty school grounds in an eerie red glow as I made my way toward the back of the gym.
They were already waiting.
Erico, Aiko, and Mizuki stood together in the shadowed area behind the gym, each carrying a small bag. The moment they saw me approaching, their eyes locked onto me with naked, devouring hunger.
Erico's smile was wide — too wide. Her massive, swollen breasts strained violently against her uniform, dark wet patches clearly visible where her nipples continued to leak. Black veins pulsed visibly beneath the skin of her neck and cleavage.
Aiko stood slightly behind her, cheeks flushed, shifting uncomfortably. The crimson patterns on her neck had spread further, disappearing beneath her collar. She looked both ashamed and excited, her thighs pressed tightly together.
Mizuki stood calmly between them, silver-grey hair swaying gently in the evening breeze. Her expression was serene, but her eyes glowed with that faint crimson light behind her glasses. A single extra eye briefly flickered open on her forehead before sinking back under her skin.
All three of them stared at me like predators who had cornered their prey.
Erico took one step forward, her voice low and dripping with lust.
"There you are, Ren…" she purred, her voice carrying that unnatural double tone. "We've been waiting for you."
Aiko bit her lip, eyes drifting down to my crotch.
Mizuki simply smiled, adjusting her glasses with one finger.
"The Mirror is calling stronger tonight," she said softly. "We can all feel it. And you… you smell even more delicious than this morning."
The crimson mark across my face and arm burned hotter at their words, sending a shameful wave of arousal through my exhausted body.
The sun had almost disappeared now, leaving the sky blood-red.
And I knew, deep down, that tonight was going to be far worse than last night.
All three of them moved at once.
Erico grabbed my right arm with surprising strength, her fingers hot against my skin. Aiko took my left arm, pressing her smaller body against my side, while Mizuki placed a hand on my lower back, guiding me forward with calm but undeniable force. Being surrounded by the three of them felt suffocating. Their combined body heat, their scents — sweet, musky, and wrong — pressed in on me from every direction. My heart hammered wildly in my chest as pure terror mixed with the burning heat of the crimson mark.
This was my nightmare.
I, who had spent my entire life avoiding people, was now being dragged forward by three girls whose bodies were no longer fully human.
We entered the gym through the side door. The moment we stepped inside, Erico released my arm and pushed the heavy door shut with a loud, metallic clang that echoed through the vast empty space. The lock clicked into place.
The gym was dark. Only faint, blood-red sunlight filtered in through the high windows near the ceiling, casting long crimson streaks across the wooden floor. The air felt thick and heavy, still carrying the faint smell of sweat from earlier PE classes.
"Perfect…" Erico whispered, her voice echoing softly.
They didn't waste any time.
Erico stepped in front of me with a predatory grin, her swollen breasts jiggling heavily as she reached out and started unbuttoning my shirt with impatient fingers. "You won't be needing this anymore," she purred, her voice layered with that unnatural resonance. She ripped the last few buttons open and yanked the shirt off my shoulders, exposing my chest and the spreading crimson veins that now crawled across my left eye and right arm.
Aiko knelt down in front of me, her hands trembling slightly with a mix of shame and hunger. She unbuckled my belt and pulled my pants down along with my underwear in one shaky motion. My cock sprang free, already half-hard despite my fear, thanks to the constant burning of the mark. Cool air brushed against my naked body as Aiko stared at my exposed cock with glassy eyes.
"So… this is what fucked us senseless last night…" she whispered hoarsely.
Mizuki moved behind me, pressing her soft breasts against my back as she helped pull the rest of my clothes off completely. Her silver hair tickled my shoulder while her hand boldly stroked my ass.
Within seconds, I was completely naked.
They pushed me down forcefully. My knees hit the wooden floor, and I sat there, fully exposed in the middle of the crimson-lit gym. My cock hung heavy between my spread legs, twitching under their hungry gazes. The spreading mark on my face and arm throbbed visibly in the red light, as if showing off.
Erico stood over me, looking down with pure lust. Her massive, vein-marked breasts strained against her half-open blouse, dark wet spots growing larger as her nipples leaked.
"Look at him…" Erico breathed, licking her lips with a tongue that was clearly longer than it should be. "Our shy little virgin, now sitting naked and hard for us. The mark suits you so well, Ren."
Aiko knelt beside me, her hand hesitantly reaching out to touch my thigh. "You're… really beautiful like this," she murmured, voice shaking. Her own crimson patterns were visible on her neck and disappearing into her cleavage.
Mizuki circled around slowly, her eyes glowing faintly behind her glasses as she took in every inch of my naked body.
"The Mirror's vessel," she said softly, almost reverently. "So much purity still left… even after everything we took from you."
I sat there completely exposed, heart racing, skin prickling under their intense stares. The crimson sunlight painted my naked body in shades of blood red. My cock continued to harden further under their gaze, betraying me completely as the mark burned hotter across my face and arm.
Erico smiled wickedly, slowly unbuttoning the rest of her own blouse, letting her grotesquely swollen, leaking breasts spill out completely.
"Now then…" she whispered, voice dripping with dark hunger, "shall we begin tonight's feeding?"
The three girls stood over my naked body like predators circling wounded prey. The crimson sunlight bleeding through the high windows painted their skin in shades of blood and shadow.
Erico was the first to move.
With a wicked, distorted smile, she slowly peeled off the rest of her uniform. Her blouse fell open completely, and she shrugged it off, letting her grotesquely swollen breasts bounce free. They were significantly larger than yesterday — heavy, vein-riddled, and constantly leaking thick streams of pearly white fluid from her darkened, puffy nipples. The liquid dripped down the curves of her tits and onto the wooden floor with soft, wet sounds.
She hooked her thumbs into her skirt and panties and pushed them down in one motion, stepping out of them. Her pussy was visibly swollen, lips puffy and glistening, with dark veins pulsing around her entrance.
As she stood fully naked, the horror became undeniable.
Two extra eyes slowly opened on her forehead, pitch black and unblinking. Another pair flickered open on her left shoulder, staring directly at me. Her smile stretched too wide, revealing rows of sharper teeth.
"Mmm… you like what you see, Ren?" Erico purred, her voice layered with multiple tones. She cupped her leaking breasts and squeezed them, causing thick white fluid to spray out in small arcs. "My body is changing so much for you… All this milk is for you to drink later."
Aiko stepped forward next, trembling with a mix of shame and uncontrollable lust.
She stripped hurriedly, almost desperately. First her blouse, then her skirt. Her bra came off, revealing her modest breasts now completely covered in spreading crimson vein patterns. Her nipples had mutated horribly — they had grown longer, thicker, and were writhing slowly like tiny tentacles, leaking sticky white fluid that dripped down her stomach.
She pulled her panties down last. As the fabric left her skin, a thick, continuous stream of white sticky fluid oozed from her pussy, running down her thighs in heavy strands. The crimson marks had spread across her chest and lower belly like parasitic roots.
"I… I can't stop leaking…" Aiko whispered shamefully, voice cracking. "Ever since you came inside me last night… it won't stop. My nipples keep moving on their own…"
She looked terrified by her own body, yet her eyes were glazed with the same dark hunger as the others.
Finally, Mizuki removed her clothes with eerie calmness.
She folded her uniform neatly and placed it aside before taking off her bra and panties. Her body was pale and deceptively elegant — until you looked closer. The sides of her puffy pussy lips had small, fleshy tentacles writhing slowly, slick with her juices. As she spread her legs slightly, a thicker, longer tentacle slowly emerged from deep inside her cunt, glistening and flexing in the crimson light. It curled lazily in the air like a living creature tasting the atmosphere.
Mizuki adjusted her glasses with one finger, completely unbothered by the nightmare growing between her legs.
"The Mirror rewards those who serve well," she said softly, her voice calm yet terrifying. "My body is becoming a better vessel… These feelers are very sensitive. They want to taste you, Ren."
All three of them now stood completely naked in front of me.
Erico with her extra eyes and leaking, mutated breasts.
Aiko with her tentacle-like nipples and constantly drooling pussy.
Mizuki with tentacles sprouting from her cunt, writhing slowly as if reaching for me.
The crimson sunlight made their mutated bodies look even more grotesque and surreal. Their marks glowed faintly, pulsing in sync with the one burning across my face and arm.
Erico stepped closer, her extra eyes on her forehead and shoulder all staring at my hard cock.
"Look at our shy boy…" she whispered with dark delight. "Sitting naked on the floor, cock twitching while three monsters stare at him. Are you scared, Ren?"
Aiko knelt down beside me, her tentacle-nipples twitching as sticky fluid continued dripping from her pussy onto the floor.
"I'm scared too…" she admitted in a small voice, "but I need you inside me again…"
Mizuki approached last, the thick tentacle emerging from her pussy curling toward my thigh, gently brushing against my skin — wet, warm, and hungry.
"The feeding begins," she whispered.
The gym felt smaller. The crimson light grew deeper.
And I realized I was completely trapped — naked, marked, and surrounded by three girls whose bodies were no longer human.
