First Glance, First Sin

I never meant for it to start this way, but once I felt his eyes on me that first real night, there was no going back. I’m Elena, forty-two, three months out of a dead marriage, living alone in this third-floor walk-up with the alley so narrow I could almost stretch out and touch the building opposite. Marcus moved in across the way six weeks ago—twenty-four, dark hair always a little messy, shoulders that filled out his T-shirts like he still hit the gym every morning. I’d caught him looking before. Accidental stuff. Me walking past my bedroom window in a towel after a shower, him standing at his own window with a beer, gaze lingering a second too long before he turned away. I’d felt the little spark then, the old exhibitionist itch I’d buried under years of suburban politeness and a husband who never once looked at me like I was worth watching.

The third night of those “accidents,” I stopped pretending. I left the curtains wide open, lights on bright, and peeled off my blouse right there in the center of the frame. My fingers worked the buttons slow. I watched his window the whole time. He was there, of course he was, leaning against the sill like he’d been waiting. When the blouse dropped and I stood in just my black lace bra, our eyes locked. No smile, no wave—just that raw, mutual decision hanging in the air between us. Heat flooded straight between my legs. I unhooked the bra and let my tits spill free, heavier than they used to be but still full, nipples already tight from the cool air and the knowledge that this stranger—this hot young neighbor—was staring straight at them. He didn’t look away. He stayed. My pussy clenched so hard I had to press my thighs together.

I took my time with the rest. Skirt unzipped, slid down my hips, kicked aside. Panties next, thumbs hooking the sides, inching them down until I was completely bare under the harsh overhead light. I cupped my breasts, thumbs brushing the nipples, and held his gaze while I did it. The rush hit me like a drug. My cunt was already slick; I could feel it coating my inner thighs. Marcus’s hand dropped to the front of his jeans. He rubbed once, slow, open about it. We were choosing this. Escalating. I turned sideways so he could see the curve of my ass, ran a hand down my stomach and between my legs, just resting my fingers there, not quite rubbing yet. The wetness greeted me instantly. I brought those fingers up, shiny under the light, and let him see. Then I closed the curtains—not all the way, just enough to end the show for the night—and went to bed with my hand buried in my pussy, coming hard while I pictured his eyes.

The next evening I prepared. Shaved everything smooth, lotioned my skin until it glowed, chose nothing to wear underneath a thin silk robe that clung when I moved. I left the curtains open from the start, lights blazing, and waited until I saw his silhouette appear. The second he settled at his window I let the robe fall open. No teasing with clothes this time—I wanted him to see me decide. I shrugged it off my shoulders and stood naked, facing him fully. My heart hammered. I lifted my hands to my breasts and began to play, rolling the nipples between thumbs and fingers, pinching until the sting made me gasp. Marcus watched, then mirrored. He pulled his shirt off in one motion, revealing a lean, hard chest and the happy trail disappearing into his waistband. His hands went to his belt. I kept massaging my tits while he shoved his jeans and boxers down. His cock sprang free—thick, already hard, the head flushed dark. He wrapped a fist around it and stroked once, base to tip, eyes locked on mine.

I slid one hand down my belly and parted my pussy lips with two fingers, showing him how wet I already was. The cool air hit my clit and I shivered. Slowly I circled it, hips rocking just a little. Marcus matched the rhythm, fist gliding up and down his shaft in the same tempo. The alley between us felt like nothing. I could almost smell him. I pushed a finger inside myself, then two, fucking them in and out while my thumb kept working my clit. He stroked faster. Pre-cum beaded at his tip; I saw it catch the light. The tension coiled tighter and tighter in my gut. I pulled my shiny fingers free and beckoned him with one crooked finger—come closer, keep going, don’t you dare stop. He answered by stepping right up to the glass, pressing his naked body against it. His cock smeared a streak of wetness on the pane. One hand braced on the window frame, the other still pumping. We were both breathing hard, mouths slightly open, performing only for each other.

That was the moment I knew we were going all the way tonight. I planted my feet wider and really started to masturbate for him—frantic, shameless, the way I’d always fantasized about being watched. Fingers plunging deep, palm grinding against my clit, free hand squeezing my breast hard enough to leave marks. My juices ran down my wrist. Marcus’s fist flew over his cock, hips punching forward like he wished he could fuck the glass. Sweat sheened his chest. I could see the muscles in his forearm flex with every stroke. I locked eyes with him and mouthed the words I was too far away to shout: watch me come.

But first I wanted to give him everything. I turned around, presented my ass, and bent at the waist until my hands braced on the windowsill. Looking back over my shoulder I spread my cheeks with both hands, exposing my dripping pussy and the tight pucker of my asshole. Then I reached back and pushed two fingers into my cunt from behind, pumping hard, the wet sounds loud in my quiet apartment. I added a third. My thumb brushed my asshole on every stroke until I pressed it there too, just the tip, circling, teasing, finally sinking in to the first knuckle. The dual stretch made my knees weak. I fucked myself like that—pussy and ass both filled with my own fingers—while Marcus stared, open-mouthed, jerking his thick cock so fast the motion blurred.

He came first. I saw the exact second it hit him: body locking, head dropping back, fist strangling the base of his cock as thick white ropes shot out and splattered against his windowpane. Rope after rope, smearing the glass, dripping down in slow glossy trails. The sight detonated me. I shoved my fingers as deep as they would go and shattered, a loud broken cry tearing out of my throat. My pussy convulsed, squirting around my hand, thighs shaking so hard I almost collapsed. I kept fingering myself through it, riding every aftershock while his cum slid down the glass and his chest heaved. We stayed like that for long seconds, both of us ruined and on display, the only two people in the world who mattered.

Still panting, sweat cooling on my skin, I straightened up and turned to face him again. Our eyes met across the alley. I lifted the hand that had been buried in my cunt—fingers glistening, coated thick—and slowly dragged them to my mouth. I sucked them clean, tasting my own sharp sweetness, never breaking his gaze. A wicked smile curved my lips. I reached for the curtain cord, ready to close the show, already aching for tomorrow night and whatever filthy escalation we would invent next.

That was when I saw her.

Standing just behind Marcus’s shoulder in the dimmer light of his apartment, staring straight at me through the cum-streaked glass: Lena. My best friend. Twenty-eight, adventurous as hell, the one person who already knew every dirty secret I’d ever confessed over wine. Her eyes were wide with shock, but underneath it—unmistakable—was pure, hungry arousal. She didn’t look away. Neither did I.
