The apartment across the hall glowed with a single lamp, its shade tilted just enough to cast long shadows over the bed. He stood in his own darkness, blinds cracked an inch, and watched as she entered the frame. She moved slowly, unbuttoning her blouse one pearl at a time, the fabric sliding from her shoulders to reveal the black lace of her bra. Her breasts rose and fell with each breath, nipples already tight against the thin material. She paused at the mirror, turning slightly, and he saw the curve of her waist, the flare of her hips, the way her skirt hugged the swell of her ass.
She reached behind her and unhooked the bra. It fell away, and her hands lifted to cup her breasts, thumbs brushing the peaks.
A soft sigh escaped her lips, audible through the thin walls if he pressed close enough. He felt his cock twitch, hardening against his jeans as she rolled her nipples between her fingers, pinching just hard enough to make her back arch. She stepped out of the skirt next, leaving only a pair of sheer panties that clung to the outline of her pussy. The fabric was already damp; he could see the darker patch where her arousal had soaked through.
She climbed onto the bed, knees spreading wide, and slid one hand down her stomach. Her fingers dipped beneath the waistband, rubbing slow circles over her clit. Her hips lifted, pushing against her own touch. The other hand returned to her breast, squeezing and tugging. He could hear the wet sound of her fingers working deeper, sliding in and out of her cunt with a steady rhythm. Her moans grew louder, thighs trembling as she fucked herself openly, unaware or uncaring of the eyes fixed on her from across the hall.
Night after night the scene repeated with small variations that pulled him closer to the glass. One evening she left the curtains fully open and wore nothing but stockings and heels. She stood facing the window, legs apart, and ran her hands over her body as if inviting inspection. Her fingers traced the lips of her pussy, spreading them so the lamplight caught the glistening pink inside. She bent forward, ass presented, and reached back to slide two fingers into herself from behind. Her breasts swung with the motion, nipples brushing the cool air. He stroked his cock in time with her thrusts, matching the pace until she came with a sharp cry, thighs shaking, juices coating her hand.
Another time she brought a toy into view. The vibrator hummed to life in her grip, and she dragged it over her clit before pushing the thick head inside. Her cunt stretched around it, lips gripping the shaft as she worked it deeper. She fucked herself with long, deliberate strokes, free hand pinching her nipples hard enough to leave red marks. Sweat glistened on her skin. Her mouth fell open in a silent moan that soon turned audible, a string of filthy encouragements to herself that floated through the night air. He came against the wall, thick ropes splattering the plaster while she shuddered through her own release, the toy still buried inside her.
The tension built across weeks. He began leaving his own light on, a small lamp near the window, so she could see the silhouette of him watching if she chose to look. She did. Her performances grew bolder. One afternoon she pressed her bare body to the glass, breasts flattened against it, and fingered herself while staring directly toward his darkened room. Her tongue licked her lips; her hips rolled in slow circles as she came, leaving a wet streak on the pane.
He finally crossed the hall one evening after she had finished. She opened the door wearing only an open robe. No words passed between them at first. She led him inside, positioned him in the chair facing her bed, and resumed her place on the mattress. This time she knew every movement was observed up close. She spread her legs wide, parted her folds, and let him watch her cunt clench around her fingers. He freed his cock and stroked it openly while she described exactly what she wanted him to see: the way her clit swelled, how wet she was, how badly she needed to be filled. When she came, she held her pussy open so he could watch the rhythmic pulses. He finished across her stomach, hot streaks landing on her skin as she smiled up at him through half-lidded eyes.
The arrangement continued without discussion. Each night she performed for the chair, sometimes using her mouth on a toy, sometimes riding it while facing him so he could see every inch disappear inside her. He watched, touched himself, and occasionally joined her on the bed when the ache became too much. The voyeurism never fully left; it simply changed distance. She would still press against the glass some evenings, knowing he stood behind her now, his hands on her hips while she came. The window remained their shared stage, the light always on, the blinds never fully closed.
