Wednesday morning light slipped through the half-closed curtains in soft, slanted bands, painting pale stripes across the rumpled sheets. Emma lay curled on her side, one leg drawn up, the sheet tangled low around her waist. Her breathing was deep and even, auburn strands fanned across the pillow. The faint, unmistakable musk of last night’s encounter still clung to her skin—rich and earthy, mixed with the sharper trace of a man’s cologne that wasn’t Alex’s. A single bead of dried sweat glistened at the hollow of her throat.
Alex woke first, heart already hammering against his ribs. He lay motionless for a long moment, staring at the ceiling, the weight of the previous evening pressing down like a physical thing. The app had promised something decisive today. He eased out of bed without disturbing her, bare feet silent on the cool floorboards, and padded to the bathroom. There, door clicked shut behind him, he pulled out his phone with trembling fingers.
The LustLink dashboard had transformed overnight. Gone were the blurred thumbnails. In their place sat crisp, high-definition recordings—multiple angles, unpixelated, mercilessly clear. One still showed Emma’s face mid-moan, lips parted, eyes heavy-lidded with unmistakable bliss. Another captured the exact moment Marcus had driven deep, her back arching off the leather couch. Alex’s stomach clenched hard. His cock twitched involuntarily in his boxers, already half-hard from the mere sight.
He returned to the bedroom just as Emma stirred. She stretched lazily, the sheet slipping lower to reveal the smooth curve of her hip. A soft sigh escaped her as she rolled onto her back, then turned toward him. Her eyes fluttered open, catching him standing there, phone still glowing in his hand. A slow, knowing smile curved her lips.
“Morning, baby,” she murmured, voice husky with sleep and something far more awake. “Did you watch any of it yet?”
The question hung between them, casual on the surface but loaded with new power. She sat up, sheet pooling at her waist, full breasts shifting with the movement. A delicious soreness pulsed between her thighs—deep, satisfying, the kind that reminded her exactly how thoroughly she had been used. Confidence bloomed in her chest, warm and addictive. She felt different this morning. Desired. Claimed. And the feeling suited her.
They moved through breakfast in a charged quiet. Toast, coffee, the usual rituals. But the app had other plans. As they finished, both their phones vibrated in unison—sharp, insistent. The screens locked simultaneously, displaying the same stark command: “Shared viewing required. Open on main television now. Compliance mandatory.”
Emma’s smile sharpened. “Looks like it’s time.”
In the living room the big TV flickered to life before either of them touched a remote. The LustLink interface took over, sleek and merciless. The full, unblurred recording began to play.
Alex sank onto the couch, throat dry. The video opened exactly where the blurred stream had left off the night before, but now every detail was razor-sharp: the way Marcus’s thick cock stretched her open, the glossy sheen of her arousal coating him on every withdrawal, the faint red marks her nails had left across his back. Emma’s voice filled the room—clear, unrestrained—”He’s so much bigger than you, baby ... I can feel him in places you’ve never reached.” The words landed like a slap.
His internal world fractured. That’s my wife. My Emma. Moaning for another man while I sat here stroking myself like a pathetic spectator. Every thrust played out in merciless detail—the wet, rhythmic slap of skin, the way her breasts bounced heavily, the exact moment her face twisted in orgasm. Shame flooded him, hot and thick, yet his cock strained painfully against his boxers, leaking steadily now, a dark wet spot spreading across the front. He couldn’t look away. Couldn’t breathe properly.
