Chapter 3

The apartment door clicked shut behind them, and the silence rushed in like water filling a vacuum. For a long moment I just stood there in the entryway, empty glass still in my hand, staring at the wood grain of the door as if it might open again and undo everything that had just happened. The air still carried the faint trace of Kristen’s sunscreen and Brad’s cologne, mixed with the lingering musk of our morning sex. My legs felt heavy, like they belonged to someone else.

I needed to get out. Needed fresh air, noise, anything to stop the loop in my head: her smile when she saw him, the way she tugged down her shorts to show him the lace thong, the casual way she kissed my cheek like I was a child being sent off to play. I set the glass on the side table, grabbed my keys and wallet, slipped on shoes without tying the laces, and reached for the doorknob.

Then I stopped.

What was I going to do outside? Walk around the block? Sit in a café and pretend to read? The thought made my stomach turn. Everyone would see me—the pale, tired husband whose wife was jogging with the kid from downstairs. They’d know. Or maybe they wouldn’t. But I would know. And worse, I’d know she was out there with him, laughing, sweating, letting him touch her ponytail while she filmed it for the world to see.

I let my hand drop from the knob.

Instead I turned, walked to the couch, and sank into it like my body had been waiting for permission to collapse. The cushions still held the faint warmth from where Brad had sat earlier, like he had claimed the spot and left his shape behind. I pulled out my phone, thumb hovering over the screen, telling myself I was just checking the time or the weather or anything normal. Anything that wasn’t her.

Instagram opened automatically. Muscle memory. Her profile was already at the top of my search history.

She had posted a story two minutes ago.

I tapped it before I could talk myself out of it.

The video was ten seconds long, filmed in selfie mode while she ran. Kristen held the phone out in front of her, arm extended, face flushed and smiling wide, ponytail bouncing with each stride. The park trail blurred behind her in greens and browns. She was breathing hard but laughing, the sound bright and breathless through the tiny speaker. “Okay, okay, Brad’s trying to keep up!” she said to the camera, voice playful. “Say hi, slowpoke!”

The camera panned slightly to the side as she angled the phone. Brad appeared in frame, running just behind her, grin wide, tank top already dark with sweat. He waved once, then reached forward and gave her ponytail a quick, playful tug—gentle but firm enough to make her squeal and swat at him without breaking stride. “Gotta keep you motivated, Kristit,” he called, voice low and teasing.

Kristen laughed harder, turning the camera back on herself for the last few seconds. But just before the video ended, she tilted the phone down a fraction—enough to catch Brad’s eyes dropping unmistakably to her ass in those black shorts. He didn’t even try to hide it. His gaze lingered, hungry, while she was still giggling and catching her breath. She caught him in the act, glanced back over her shoulder, and busted him with a teasing “Eyes up here, perv!” before the clip looped.

Ten seconds of her running, laughing, Brad’s hand in her hair, his eyes on her ass, her calling him out like it was the funniest thing in the world. I watched it again. And again.

Each loop felt shorter, sharper. The way her head jerked back playfully when he pulled. The way she didn’t pull away. The way she looked straight into the camera—into me—while he touched her, while he stared at her body like it was already his. The way she giggled when she caught him looking, not mad, not embarrassed, just amused. Like it was normal. Like it was fun.

My thumb hovered over the screen. I could swipe it away. Close the app. Turn off the phone. Pretend I hadn’t seen it. I didn’t.

I played it one more time, volume low, ear close to the speaker so I could hear her laugh clearly, hear the exact tone when she said his name, hear the playful scold when she busted him staring. The sound went straight through me, twisting the heat in my gut into something darker, something that made my soft cock stir traitorously against the sweatpants. Because he was winning.

Not just her body. Not just her nights. He was winning her laughter, her glances, her casual teasing. He was turning my wife into someone who giggled when a kid half her age stared at her ass like he owned it. He was turning my home into a place where he could walk in, sit on my couch, pour himself water from my fridge, and thank me for being a good sport about it.

And I was letting him.

I set the phone down on the cushion beside me, screen still glowing with her frozen smile and Brad’s hand frozen in her ponytail.

The apartment was quiet except for the faint hum of the fridge and the occasional car passing outside. I didn’t move. I just sat there, staring at the frozen frame, letting the loop play in my head even after the screen went dark. Waiting.

Not for them to come back, but for whatever came next. For the next photo she’d send me from the trail. For the next time she’d giggle at something he said. For the next time I’d open the door for him and smile while he walked in like he owned the place.

Kristen’s message arrived with a soft buzz that cut through the apartment’s silence like a knife. I was still on the couch, legs numb from sitting too long in the same position, phone resting face-up on my thigh where I had left it after the story video looped itself into my brain. The screen lit up with her name and the notification badge: one new message from her private chat.

I picked up the phone with hands that felt disconnected from the rest of me. Opened it before the rational part of my mind could intervene.

The photo loaded in high resolution, taken in portrait mode against the green backdrop of the park trail. Kristen stood in a patch of dappled sunlight, one arm extended to hold the phone for the selfie, the other casually lifting the hem of her neon-pink sports bra just enough to expose the smooth, sweat-slick underside of her breasts. The fabric was pulled up high, nipples barely covered by the edge of the material, the sheen of perspiration catching the light and making her skin look oiled and golden. Sweat had darkened the edges of the bra and trickled in thin rivulets down her cleavage, pooling at the waistband of her black shorts. Her cheeks were flushed from the run, lips parted in a breathless smile, eyes bright and playful as they looked straight into the lens.

The caption sat beneath it in her usual cheerful font: “Brad says I look hot when I’m sweaty.”

Nothing more, just his words on her typing. His judgment. His approval. I stared at the photo. Twenty minutes passed. I know because I kept glancing at the clock in the top corner of the screen, then back down to her face, then back to the time, as if checking would make the image less real or make the minutes stop stretching. Twenty minutes of the same frozen moment burning into my retinas: my wife, half-exposed in the middle of a public park, sweat-glistening and smiling, telling me—explicitly telling me—that Brad thought she looked hot like this. That she agreed enough to lift her bra for the photo. That she wanted me to see it, to know it came from him.

My thumb hovered over the screen, trembling slightly. I could zoom in. I could study the way the sweat traced paths down her sternum, the way the bra fabric clung to the curve of her breast, the way her eyes looked straight into the lens like she knew exactly what this would do to me. I didn’t zoom. I didn’t need to. The photo was already too sharp, too intimate, too much. Every detail was etched in perfect clarity: the slight upward tilt of her chin, the way her ponytail still looked a little mussed from where Brad had tugged it in the earlier video, the flush on her neck that might have come from running or from his eyes on her or from both.

My cock stirred again in the sweatpants. Not full hardness. Just that low, aching twitch that reminded me how quickly I’d finished inside her this morning while she silenced me with her hand over my mouth. How she’d played with my softening dick afterward like it was a toy. How she’d decided to stay horny all day because it would be “fun.”
