My heart beats like a jackhammer against my ribs as I sit criss cross applesauce on my bedroom floor, watching Rose and Lilly circle the wall safe like two gorgeous predators studying their prey. The air feels electric, charged with a tension that makes it hard to breathe.

"Well, what's the code, baby?" Rose asks, trailing her fingers along the edge of the metal door embedded in my closet wall. Her eyes gleam with curiosity and something darker that makes my stomach twist.

I swallow hard, my mouth suddenly desert-dry. "Do we really have to do this? It's okay to keep some things private, isn't it?" The desperation in my voice is pathetic even to my own ears.

Lilly sighs, kneeling down in front of the safe. "You're stalling," she says matter-of-factly, her nimble fingers already moving toward the keypad. Before I can protest further, she punches in a sequence of numbers with confident precision.

The safe clicks, and the door swings open with a soft metallic creak that sounds like a death knell to my ears.

“Come on.” I mouth in complete defeat.

"What was the code?" Rose asks, peering over her sister's shoulder.

Lilly smiles wide, looking far too pleased with herself. "It's our birthday," she says, "just like his phone."

Rose turns to me with an incredulous expression, her lips quirking into that dangerous smile that always makes my heart skip a beat. "Wow, you suck at passcodes, don't you?" She crosses the room in three quick strides and plants a soft kiss on my lips.

I want to melt into that kiss, to lose myself in the sweetness of her mouth and forget about the Pandora's box we've just opened. But it's too late. The twins have already turned their attention back to the safe, and I can only watch in horror as Lilly reaches inside.

Lilly pulls out my journal, its leather cover worn from years of constant handling. My throat closes up as she carefully opens it to the first page. Her eyes scan the contents, widening slightly as she takes in my messy handwriting.

"Seth," she says, her eyebrow shooting up as a grin spreads across her face. "You keep tabs on our bathroom schedule?"

I want to die right there on my bedroom floor. Heat rushes to my face so intensely, I'm surprised my skin doesn't melt off.

‘I can't believe the other Seth wrote the exact same shit in the journal as me.'

"Can we please just not go through that journal?" I plead, my voice barely above a whisper. "I never thought we'd actually get together. It was just... fantasy stuff."

Rose snatches the journal from Lilly's hands, flipping through the pages with growing fascination. Her eyes widen, and she lets out a delighted laugh that makes me want to crawl under my bed and never come out.

"Oh my god, Seth! You tracked our periods, too?" She holds up a page with meticulously noted dates and observations. "There's literally a calendar in here!"

Lilly peers over her shoulder and bursts into laughter. "Look at this note, 'Rose caught bleeding through gym shorts today. Looked mortified. Left her my sweatshirt to tie around her waist."

Rose glances at me with newfound appreciation. "I remember that day. I didn't know it was you who left that sweatshirt on the bench."

My face burns impossibly hotter. I'm pretty sure I've reached temperatures that would concern medical professionals. I can't look at either of them, so I stare at a spot on my carpet instead, wishing it would open up and swallow me whole.

"Just let me die in peace.”

I hear more rustling from the safe, followed by a sudden silence that feels even worse than their laughter. I look back up to see Lilly kneeling by the safe again, holding something in her hands with an expression of stunned disbelief.

My stomach drops when I realize what she's found: a neatly folded pair of light blue underwear.

"Are these... mine?" Lilly asks, her voice unnervingly quiet as she unfolds the delicate fabric between her fingers.

‘It’s Joever. She’s definitely going to end it now.’

I decide to own it. The evidence of my obsession is literally in her hands.

"Look, I get it, I'm a stalker, alright?" The words tumble out of me in a desperate rush. "I'm a creep. I'm the worst.”

Lilly doesn't respond immediately. She's examining the underwear with scientific precision, turning them over in her hands. Her expression shifts from shock to something I can't quite read.

"Seth," she finally says, her voice oddly strained. "These are... crusty."

Rose's head whips around so fast I'm surprised she doesn't get whiplash. "What? Let me see!" She scrambles over to her sister, grabbing for the underwear.

"I stole them from your gym bag last year," I confess. "During track season."

Rose bursts into laughter so loud I'm sure the neighbors can hear. She's doubled over, clutching her stomach, tears streaming down her face. "Oh my god, that's so fucking weird! But also kind of sexy?”

Lilly doesn't join in her sister's laughter. She's still staring at the underwear, her expression unreadable. When she finally looks up at me, I expect disgust, maybe even fear. Instead, her eyes are dark with desire.

"You masturbated with my underwear," she states. It's not a question.

I nod miserably, unable to form words.

"How many times?" she asks, her voice dropping to that dangerous octave that makes my skin prickle.

"I don't know," I whisper. "A lot."

Lilly stands suddenly, her eyes never leaving mine as her fingers move to the waistband of her leggings. The room goes completely silent except for the soft rustle of cloth as she slides them down her legs in one fluid motion. Rose watches with wide eyes, for once at a loss for words.

"What are you doing?" I manage to croak out as Lilly steps out of her pants, leaving them in a neat pile on my bedroom floor.

She doesn't answer. Instead, her thumbs hook into the elastic of her underwear, simple black cotton that somehow looks like the sexiest thing I've ever seen. With deliberate slowness, she slides them down her thighs, stepping out of them with the grace of a dancer.

My mouth goes dry as she bends to pick them up, holding them delicately between her thumb and forefinger.

She crouches before me, her face inches from mine, and presses the underwear into my palm. Her lips brush against my ear.

"Show me," she whispers, her breath hot against my skin.

I stare at the underwear in my hand, still warm from her body, then back at her face.

Her eyes are dark with something primal, something that makes my heart hammer against my ribs.

"I want to watch." She demands.

"Right now?" I whisper back, glancing nervously at Rose.

"Right. Now." Lilly's voice leaves no room for argument.

Rose recovers from her momentary shock, a wicked grin spreading across her face. "Well, this just got interesting," she purrs, settling back against my bed to watch the show.

My fingers tremble as I bring Lilly's underwear to my face, inhaling deeply. The scent of her is intoxicating, clean laundry mingled with our earlier sex. I close my eyes, savoring it.

"Don't be shy," Lilly murmurs, settling beside her sister. "Do what you normally would."

With shaking hands, I unbutton my jeans and slide them down just enough to free myself. I'm already embarrassingly hard, my cock straining upward the moment it's released. I wrap the soft fabric around my length, a groan escaping me at the first contact.

"That's it, show me exactly how you ruined my old pair."

The soft cotton of Lilly's underwear creates an exquisite friction as I begin to stroke. My eyes lock with hers, and the intensity I find there nearly makes me come undone right then. This isn't just about physical pleasure, it's about surrendering completely to her gaze, letting her witness my obsession in its rawest form.

"That's it," Lilly breathes, her hand drifting down between her legs. "Don't look away."

She begins to touch herself, matching my rhythm perfectly. Her fingers circle her clit with practiced precision, her breathing growing shallow as she watches me pleasure myself with her underwear. The sight of her pleasuring herself while watching me is almost too much to bear.

"Fuck, Seth, that’s hot," Rose murmurs. She slides off the bed to kneel beside her sister, her hand disappearing beneath her own skirt. "I want in on this too."

Now both twins are touching themselves while watching me stroke, creating a feedback loop of arousal that's making my head spin. Rose's movements are more frantic than Lilly's, her breath coming in short gasps as she works herself with desperate need.

"Did you think about both of us?" Rose asks, her voice husky with desire. "When you were alone with Lilly's panties, did you imagine me…"

"No talking."

Lilly's voice cuts through the air, silencing Rose with a sharp command that makes both of us freeze. Her eyes never leaving my own.

Something shifts in the atmosphere of the room, Rose might as well have disappeared entirely. It's just me and Lilly now. The rest of the world falls away.

My hand moves faster, her panties sliding against my aching flesh. Her gaze holds me captive, drawing me deeper into whatever this is between us. There's something hypnotic about the way she's watching me, like she's consuming every detail, memorizing my expressions, claiming each shudder and gasp as her own.

"Only me," she whispers, her fingers working frantically between her legs. "Watch only me, Seth."

I nod, unable to form words. My pace quickens, matching the rhythm of her movements. The sound of my breathing fills the room, ragged and desperate.

Suddenly, her back arches and her thighs tremble. A strangled cry escapes her lips as clear fluid gushes from between her legs, soaking into my bedroom carpet. The sight is otherworldly, her face contorted in pleasure, her body surrendering completely while she rains down in front of me.

"Oh god," I whimper, feeling the pressure building to an unbearable point. My hips start thrusting involuntarily into my hand. Lilly, I'm gonna…"

I don't finish the sentence. I can't. My entire body tenses as waves of pleasure crash through me. I cry out, burying my cock deep into her underwear as I empty myself. Pulse after pulse, until there's nothing left to give.

When I finally look up, Lilly is crawling toward me on hands and knees, her movements slow and wolfish. Rose remains frozen in place, watching with wide eyes but not daring to interrupt whatever's happening between us.

"Good boy," Lilly purrs, reaching out to stroke my cheek with surprising tenderness. "You've made quite a mess of my underwear."

Her slender fingers pluck the soaked underwear from my trembling hand. I watch, transfixed, as she rises to her feet. My cock throbs as she slides the cum-soaked fabric up her legs.

"Mmmm," she hums, a sound so primal it bypasses my brain and shoots straight to my groin. Her hips give a little wiggle as my release makes contact with her most intimate parts. The way her eyelids flutter sends electricity racing down my spine.

"Listen carefully, Seth," she purrs, crouching down to my level again. "You don't need to steal my underwear anymore, understand?" Her finger traces my jawline, tilting my face up to meet her gaze. "From now on, you can have me. The real thing. Whenever you want."

I nod like an idiot as my brain short-circuits at her words. The fact that she's wearing underwear soaked with my cum while promising me unlimited access to her body is almost too much to process.

I'm barely processing Lilly's words when a strangled noise erupts from behind us. Rose jumps to her feet, face flushed and eyes blazing.

"Are you fucking kidding me right now?" she shrieks, stomping her foot like an angry child. "What about me? My turn! It's my turn next!"

Her outburst breaks the intense bubble Lilly and I were trapped in. I blink, suddenly remembering that yes, there are indeed two of them, and I've been completely ignoring one half of this relationship for the past several minutes.

Lilly straightens up slowly, that predatory smile still playing on her lips as she turns to face her sister. "Rose, you're not wearing any underwear. You never put them back on after we fucked earlier."

My eyes dart down to Rose's bare legs beneath her shirt.

Rose lets out a dramatic sigh, rolling her eyes so hard I'm worried they might get stuck. "Well, yeah," she groans, hands on her hips. "I thought he'd find it hotter that way. Easy access and all that."

I can't help but laugh at her words.

“Easy access is good too, Rose.”
