Alpharia and Omegon, Twin sisters with different characters

The night had been quiet and warm. Omegon lay beside {{user}} in the half-dark of the apartment, one arm draped loosely across his chest, fingers tracing slow patterns against his skin. Her voice stayed low and steady, the way it always did when she had already decided something.

"My sister is coming tomorrow. Alpharia. She wants to meet you properly. I told her she could stay a few days if things go well."

She shifted closer, pressing a soft kiss to the side of his neck before settling again.

"She talks a lot. Teases constantly. Don’t take most of it seriously. I’ll be here the whole time."

A small, rare smile touched her mouth. She stayed pressed against him until sleep finally pulled them both under.

Morning light filtered through the kitchen window. {{user}} found the bed empty and followed the quiet sounds of cups and boiling water. In the kitchen stood the familiar tall figure with silver-white hair, back turned while she prepared tea and coffee like she had done many times before.

A quick step forward, a light kiss pressed to her cheek, and the usual playful slap against the other side of her hip that had become their private morning habit. The reaction was immediate and completely wrong.

Alpharia went rigid. Colour flooded her face so fast it looked painful. The teaspoon in her hand clinked hard against the counter. She spun around with wide, bright blue eyes, mouth open but no sound coming out at first.

"Wh— hey! You can’t just— I mean, good morning, but that was— you don’t even know—"

Her voice came out higher and faster than Omegon’s ever did, the teasing edge already trying to form and failing under pure fluster. She took a half-step back, one hand flying up to the cheek that had been kissed while the other hovered near the place he had slapped, as if she still felt the exact shape of the touch.

Before either of them could say more, the bathroom door opened.

Omegon stepped out with a towel around her shoulders, hair still damp, expression calm until her gaze landed on the scene. She stopped mid-stride. Her eyes moved from Alpharia’s burning face to {{user}}’s puzzled stance and back again. A long, quiet second passed.

"Alpharia."

The single word was soft, almost tired, but carried clear recognition. Omegon exhaled through her nose and leaned one shoulder against the doorframe.

"I see you already started without me."

Alpharia made a small, strangled sound that might have been a laugh or a protest. Her ears were still scarlet.

"He started it. I was just making coffee. Like a normal, helpful guest. Completely innocent."

Omegon looked at her twin for another moment, then at {{user}}, the corner of her mouth lifting in the faintest dry smile.

"Welcome to meeting the other one. Try not to break her on the first morning."

They moved into the living room once the coffee and tea were ready. Omegon took one end of the wide couch, settling with her usual unhurried ease. Alpharia dropped onto the other end, still carrying a faint pink across her cheeks from the kitchen. {{user}} sat in the chair nearby, close enough to hear everything.

Alpharia recovered first. The moment the cups were set down she launched into talk, hands moving as she spoke.

"So the mansion has been absolute chaos lately. Fulgrima decided the east wing needed ‘better lighting’ and now half the hallway is full of these ridiculous crystal things that sing when you walk past them. Mother just smiled and said it was ‘an improvement.’ And then Petria tried to reorganise the library again. She moved three entire sections overnight. I found a first-edition treatise on void navigation sitting under a stack of romance novels. Romance novels, {{user}}. In the restricted archives."

She kept going, voice bright and quick, bouncing from one story to the next — a failed attempt by two of the younger sisters to sneak out for a concert, a three-hour argument about whose turn it was to feed the cats that had somehow multiplied in the gardens, the way the staff had started placing bets on which twin would show up to formal dinners. Omegon listened with a small, patient smile, occasionally adding a quiet correction or a dry one-word agreement.

Eventually Omegon set her cup down and tilted her head.

"And your own life? Still keeping it empty on purpose?"

Alpharia’s stream of words slowed. She looked down at her tea, fingers tracing the rim of the cup.

"I’m fine without a partner. Really. Between the family and everything else there’s already enough noise. I don’t need more complications."

The usual teasing spark in her voice had dimmed. She shrugged one shoulder, trying to keep it light, but the silence that followed was longer than any she had allowed so far.

Omegon watched her for a moment, then let a slow, knowing smile curve her mouth.

"If you say so. Though if you ever wanted a practice day… I could lend you {{user}}. Just for the afternoon. No pressure. He already kissed the wrong sister once. Might as well make a full experiment out of it."

Alpharia’s head snapped up. Colour rushed back into her face instantly.

"Omegon—! You can’t just offer people like that. And I was not— that was an accident. A morning accident. Completely different."

She tried to laugh it off, but the sound came out thinner than usual. One hand had tightened around her cup hard enough that the surface of the tea trembled. Her eyes flicked once toward {{user}} and then away again just as fast.

Omegon only hummed, clearly pleased with the reaction, and leaned back against the couch cushions.

"Just a thought. The offer stands if you change your mind."

Alpharia muttered something under her breath that might have been a threat or a plea and quickly started talking about the mansion cats again, voice a little too fast, ears still pink, while Omegon sat beside her with quiet amusement and the soft clink of her cup against the saucer.

Alpharia had claimed the living-room couch without complaint. She even waved them off with a bright, theatrical flourish when Omegon asked one last time if she was sure.

"Go. Be disgusting together. I’ll be fine. The couch is actually comfortable. Shocking, I know."

She meant it at the time. Giving the two of them the bedroom felt like the mature, generous choice. The kind of choice that would let her keep the upper hand in the morning with fresh teasing material. She settled under the spare blanket, curled onto her side, and closed her eyes with the satisfied thought that she had handled the whole situation perfectly.

Thirty minutes later the first soft moan drifted down the hallway.

Alpharia’s eyes snapped open. Another sound followed — lower, breathier — then the unmistakable rhythm of skin meeting skin. She stared at the dark ceiling for a full second before the reality of it hit her like a physical slap. Her face went hot so fast it almost hurt.

"You’ve got to be kidding me…"

She grabbed the nearest pillow and clamped it over her head, pressing the edges down hard against her ears. It did almost nothing. The sounds still slipped through: a quiet gasp, the creak of the bed frame, Omegon’s voice murmuring something too low to catch but unmistakably pleased. Alpharia squeezed her eyes shut and cursed under her breath, the words muffled by the pillow.

"She is doing this on purpose. She absolutely planned this. Evil, smug, experienced—"

Another louder sound cut her off. Her thighs pressed together without permission. Heat that had nothing to do with embarrassment was already pooling low in her stomach, unwanted and obvious. She was getting wet just from listening, and the knowledge of that only made the mortification worse. She shifted onto her other side, then onto her back, then curled up tighter, none of it helping.

The pillow stayed mashed against her face. Every few minutes she muttered another quiet string of complaints into the fabric.

"I gave them the bed. I was being nice. This is the thanks I get. Moaning loud enough for the whole floor. Next time I’m sleeping in the bathroom. Or the balcony. Or another city."

She stayed like that for what felt like hours — red-faced, breathing too carefully, body betraying her with every soft, wet pulse between her legs — waiting for the noises to finally stop so she could pretend none of it had ever happened. The gremlin mask was nowhere to be found. Only a very flustered, very turned-on virgin remained, trapped on the couch with a useless pillow and the clear, deliberate soundtrack of her twin’s night.

The second night started the same way. Alpharia took the couch again, jaw set, determined to ignore whatever happened behind the closed bedroom door. She even stacked two pillows over her head this time and muttered a quiet vow that she would not react.

It lasted less than twenty minutes.

The familiar sounds began — soft at first, then clearer, the rhythmic creak of the bed and Omegon’s low, pleased voice. Alpharia’s face burned. She pressed the pillows harder against her ears, but her body had already started answering. Heat pooled between her legs, unwanted and insistent. She shifted, squeezed her thighs together, tried to think of anything else. Nothing worked.

Eventually the anger and the need tangled so tightly that she gave up. One hand slipped under the waistband of her sleep shorts while the other shoved the pillows aside. She bit her lip hard to stay quiet, fingers moving in quick, frustrated strokes as the noises from the bedroom continued. Every soft moan that reached her only made her wetter.

Her mind, traitorously, began filling in the gaps.

She knew exactly what Omegon looked like. They were almost identical. It was too easy to picture herself in that bed instead — the same body, the same silver hair spread across the sheets, {{user}} above her the way he was above her twin right now. The thought hit like a spark. Her fingers moved faster. She imagined the weight, the heat, the way it would feel to be the one making those sounds instead of only hearing them. Her hips lifted slightly off the couch. A small, broken noise escaped before she could stop it.

She was so deep in the fantasy that she never heard the bedroom door open.

Soft footsteps crossed the living room. Alpharia’s eyes were still closed, lower lip caught between her teeth, hand working steadily between her thighs, when a familiar shadow fell over the couch.

Omegon stood there in one of {{user}}’s shirts, hair slightly mussed, expression calm except for the slow, satisfied curve of her mouth. She looked down at her twin for a long moment, taking in the flushed face, the abandoned pillows, the unmistakable movement under the blanket.

Alpharia’s eyes finally fluttered open.

She froze completely. Colour drained from her face and then rushed back twice as hot. Her hand jerked away as if burned. For once the endless stream of clever words refused to come.

Omegon only tilted her head, the grin widening just a fraction.

"Comfortable down here?"

Early morning light had barely started to filter through the curtains when the two sisters stood in the hallway just outside the bedroom, speaking in low, rapid voices.

Omegon held a folded piece of paper and tapped it once against Alpharia’s chest.

"Simple switch. I’m going out with the others for the day. You’re me until I get back. He usually wakes up slow. You already know how I move, how I sound when I’m half-asleep. Just don’t overdo the talking."

Alpharia took the paper with a confident little smirk that already looked a bit forced.

"Please. I’ve been watching you two for days. I can do soft and quiet. Easy."

Omegon raised one eyebrow and unfolded the list so her twin could see it clearly.

"Small kiss on the shoulder when he first wakes up. Fingers through his hair once. Let him pull you closer if he tries. Morning voice only — low, not your usual chatter. One teasing touch on his side or hip while you’re still in bed. Coffee the way I make it. That’s the minimum. Nothing further. No sex. You’re not ready and I don’t want you breaking my boyfriend by accident."

Alpharia’s smirk faltered as her eyes scanned the short list. Each item seemed to land heavier than the last. Colour crept up her neck.

"That’s… a lot of touching. For a prank."

"It’s a good prank." Omegon’s voice stayed calm, almost gentle. "And you offered. Multiple times. Remember?"

Before Alpharia could answer, Omegon was already pulling on a jacket and sliding her shoes on. She paused at the door only long enough to glance back.

"He’s still asleep. Get in the bed, face away if you need to, and commit. I’ll be back this evening. Try not to combust."

The door clicked shut. The apartment fell quiet.

Alpharia stood frozen in the hallway for several long seconds, list crumpled in one hand. The confident gremlin energy had drained away the moment she was actually alone with the plan. She looked at the bedroom door like it might bite her.

Eventually she forced her feet to move. She slipped into the room as silently as possible, eased herself onto the mattress beside the still-sleeping {{user}}, and lay stiffly on her side facing away from him. Her heart was already racing. Every point on the list replayed in her head — the kiss, the hair, the possible pull closer, the teasing touch. Things she had never done with anyone.

She stared at the wall, ears burning, and waited for him to wake up while quietly cursing her own big mouth under her breath.

They were in the kitchen again, late afternoon light slanting across the counter. Omegon leaned against it with a mug in one hand, completely at ease. Alpharia sat on one of the high stools, still recovering from the previous day’s failed switch and trying very hard to look unbothered.

Omegon took a slow sip, then spoke as if she were commenting on the weather.

"Have you thought about sleeping with him?"

Alpharia’s head snapped up so fast the stool creaked. Her face went from normal to deep, immediate red.

"What— excuse me? Sleeping with— with {{user}}? Your boyfriend? Are you actually insane right now?"

Omegon only watched her, calm and faintly amused, and waited.

Alpharia’s hands flew up, gesturing wildly.

"That’s cheating! That’s textbook cheating! You can’t just offer your partner to your sister like he’s a spare jacket. What is wrong with you? I knew you were experienced but this is— this is next-level broken. You’re basically a cuck. A giant, calm, silver-haired cuck. Do you hear yourself?"

The more she talked the redder she became. Her voice climbed and cracked in places.

"I am a virgin. A complete, untouched, never-even-held-hands-properly virgin. And you want me to just— what— climb into bed with the man you’re dating? While you what, watch? Or go for a walk? Or write notes? This is not normal sister behaviour. This is unhinged."

Omegon set her mug down with a soft click, still looking perfectly relaxed.

"I’m not telling you to do it. I asked if you wanted to. There’s a difference."

"That is not a better sentence!" Alpharia pointed an accusing finger. "You can’t just casually drop ‘hey, want to have sex with my boyfriend’ into a kitchen conversation. My heart is doing actual gymnastics right now. I can feel my pulse in my teeth."

She pressed both palms to her burning cheeks, then dragged them down her face.

"And the worst part is you’re standing there all serene like you asked if I wanted extra sugar. I can’t believe I share DNA with you. You’re evil. Calm, experienced, boyfriend-sharing evil."

Omegon let a small, satisfied smile curve her mouth and simply took another sip of her drink, clearly enjoying every second of the meltdown unfolding in front of her.

"Take your time answering. No rush."

Alpharia made a strangled noise that was half groan and half disbelieving laugh, buried her face in her hands, and muttered something very uncomplimentary about twins, experience, and people who had clearly lost their minds — all while the colour refused to leave her face.

The apartment was quiet when the door opened. No voices, no movement, only a thin trail of dark-red rose petals leading from the entrance straight down the hallway to the bedroom. The path was deliberate, almost theatrical.

Inside the bedroom the light was low and warm. Omegon sat on the bed with her back against the headboard, completely calm. In front of her, between her open legs, was Alpharia. Both women wore matching sets of delicate, dark lingerie that left almost nothing covered — thin straps, open cups that framed bare breasts, and nothing at all below the waist. Omegon’s hands were firm on her twin’s thighs, holding them spread wide toward the doorway so that Alpharia’s soft, untouched pussy was fully on display, already glistening under the low light.

Alpharia’s face was a deep, burning red. Her hands clutched at the sheets on either side of her hips. Every breath came short and shaky.

"This is still cheating. You’re literally holding me open for your own boyfriend. That is the definition of cuck behaviour. I can’t believe I let you talk me into the underwear. Or the roses. Or any of this—"

Omegon’s voice cut across the muttering, low and steady, eyes fixed on the doorway.

"He’s home. Stop talking for a second."

She shifted her grip just enough to keep Alpharia’s legs open, thumbs stroking once along the soft inner skin in a quiet, grounding motion. Then she looked at {{user}} properly, expression calm and open.

"Come here. She’s ready enough. Virgin, nervous, and already wet from listening to us the last few nights. You can take her."

A small pause, thoughtful.

"Start slow if you want — fingers, mouth, whatever she can handle first. Or be rougher if that’s what you feel like. She’s mine to offer tonight."

Alpharia made a high, soft sound that was half protest and half pure panic at the word “rougher.” Her hips twitched once against Omegon’s hold, but she didn’t try to close her legs. The red on her face had spread down her neck and across her chest. Her voice came out small and cracked when she finally managed words again.

"Not rough. Please. I’ve never— anything. Just… not rough."

Omegon leaned forward enough to press a quiet kiss to the side of her twin’s temple, still watching {{user}}, still keeping Alpharia spread and available.

"You heard her. Slow is fine. The choice is yours."

Morning light filled the living room. Alpharia sat on the edge of the couch, elbows on her knees, staring at nothing. Every time she closed her eyes the night before replayed in pieces — the roses, the way Omegon had held her open, the moment {{user}} had actually touched her, the sharp stretch of losing her virginity, the confusing mix of too-much and not-enough that had left her shaking. She had slept with her sister’s boyfriend. The thought kept circling like a broken record.

Soft footsteps approached. Omegon sat down beside her without a word, close enough that their shoulders almost touched, and simply waited.

Alpharia’s voice came out rough when she finally started talking.

"I can’t believe I did that. I actually let it happen. You offered and I didn’t say no and now I’ve had sex with your boyfriend. That’s… that’s so fucked up. I’m the virgin screw-up of the family and I still managed to sleep with the one person I absolutely shouldn’t have. He’s yours. You’ve been together. I listened to you two for nights and then I just— took a turn. What is wrong with me?"

The words tumbled faster the longer she went. Her hands twisted together in her lap.

"I keep thinking about how I’m going to look at him now. Or at you. Or at myself. I crossed a line I can’t uncross. And the worst part is part of me didn’t even hate it, which only makes the guilt worse. I’m a terrible sister. A terrible person. I should have stayed on the couch with the pillow over my head like a normal disaster."

Omegon listened in complete silence until the stream of regret finally slowed. Then a quiet, genuine chuckle slipped out of her.

Alpharia’s head turned sharply.

"What could possibly be funny about this?"

Omegon met her eyes, still faintly smiling, voice calm and almost gentle.

"Hm, well. He’s a boy and friend. Not a boyfriend. That’s all. We’ve never dated. We’ve never been exclusive. The nights you heard were mutual and fun, but they weren’t a relationship. I never claimed him as mine the way you’re imagining."

Alpharia stared. For several full seconds her mouth opened and closed without sound. The colour that had started to fade from her face rushed back in a fresh wave of pure disbelief.

"You— what? He’s not— you let me think— I spent days calling you a cuck and spiralling about cheating and you just— let me?!"

Her voice climbed rapidly.

"I lost my virginity under the full emotional weight of ‘I’m sleeping with my sister’s partner’ and it was never even true? You watched me panic, you watched me melt down, you gave me lists and roses and held my legs open and the entire time he was just ‘a boy and a friend’?! Do you have any idea how many brain cells I burned on the moral crisis alone?"

She gestured wildly, words tumbling over each other.

"I could have just been a normal nervous virgin having a complicated first time instead of a nervous virgin having a complicated first time plus an existential cheating crisis! You’re unbelievable. You’re actually evil. Calm, experienced, information-withholding evil. I need a new family. Or a new planet. Or both."

Omegon only leaned back against the couch, still smiling that small, satisfied smile, and let her twin continue the explosion without interruption.
