We had phone sex while his GF led a sales meeting on zoom next door. (Part 4) (Dirty Little Secret - Part 54) [F20s/M20s][Series][Cheating][FWB]

But I heard it. The soft shuffle. Sheets. Movement. A faint wet sound in the background.

Then her voice. Muffled. But right there.

She wasn’t muted.

And then... then I heard it:

“What are you doing?” she asked. Quiet. Curious. Caught off guard.

He barely hesitated.

“Watching porn.”

I froze. My fingers still deep, my whole body on edge.

Her voice went quiet.

And then?

Nothing. No footsteps. No protest. No door slam.

Just silence. And the sound of the bed creaking.

My heart leapt. I couldn’t breathe.

She joined him.

There was a pause. Then the soft creak of the bed. Shifting. Moving.

I didn’t dare speak. Didn’t dare breathe.

Then I heard it. The wet sound of a kiss. Slow. Deep. Her little gasp. The slide of skin.

I slid my fingers back in. Slowly. Quietly.

He wasn’t on the phone anymore. Not really.

She was.

The moan she let out when he kissed lower... barely stifled. Then the bedsprings creaked.

My whole body reacted. I bit down hard on the edge of the pillow, one hand between my legs, the other gripping the phone.

They didn’t talk.

Not a word.

And that was worse.

Because all I could do was listen... to the sound of his mouth between her legs, wet and filthy and familiar. The sounds I knew too well. The ones that used to be just mine.

Now she was writhing under him. And I was right there for it.

Her breathing was hitched. Gasping. Bedsprings rocking harder now. I could hear the wet, open sounds of his tongue working her. No shame. No silence.

My fingers moved faster.

She moaned again... longer this time. Shaky. She tried to quiet it, but failed.

My thighs were already trembling.

He grunted. That low sound he makes when he’s hard—when he’s about to fuck.

And then I knew.

He pushed into her.

I heard the shift of weight. The exhale. The messy, deep sound of his cock sliding inside her soaked pussy.

I whimpered.

They still didn’t speak. But their bodies did.

The rhythm built slowly at first. Soft, deep strokes. The bed started hitting the wall. Lightly.

Then harder. Faster.

She moaned into his mouth, trying not to make noise, trying so hard to be good, but I could hear it... every little muffled gasp, every slap of skin against skin.

And I was losing it.

My fingers were soaked. My hand was aching from how tight I was circling my clit. But I needed it. Needed to cum to the sound of them fucking while I lay on the other end, forgotten but still listening.

He grunted again. Deep. Rough. The way he sounds when he’s fucking her like he doesn’t care if she walks funny after.

I could hear it in her breath. She was close. I knew the sound. I knew it.

She came first.

Her body shook. Her moan cracked. She tried to bite it back, but it still escaped... half sob, half scream.

The bed frame slammed against the wall.

I gasped. I came too.

Hand over my mouth, hips bucking off the bed, legs shaking around my wrist, soaking my sheets, soaking myself... while they fucked just a room away, like I didn’t exist.

He didn’t stop. Kept fucking her through it.

The rhythm turned desperate. Sloppy.

He came with a deep growl. Thrust hard. Then again. Then again.

And then it was just the sound of them breathing. Both of them. Spent.

I stared at the ceiling, body trembling, pussy throbbing, still holding the phone on speaker. Still wet. Still alone.
