The wife, Katie, of a polyamorous couple invites her girlfriend, Erika, over. They head to the bedroom and begin making out and pleasuring each other. The husband, Terence, overhears from outside the bedroom. He's very aroused and masturbates to the sound of them for just a little bit, deciding to stop to give them privacy. The two women take a break to have something to eat and Terence confesses to what he did. They say that if he wants to come in next time he can. After eating they return to the bedroom and all three climb under the blankets. The two women get back to making love while Terence lays in the dark, listening to them kissing, moaning, and fingering each other. Katie asks if he'd like to join. He tells her she should keep fucking her girlfriend. After a while Erika pauses for a moment between kisses and admits she would like to see him fuck Katie. She gets on all fours and he fucks her. Erikais mesmerized, fingering herself while she watches her girlfriend take his cock.

Chapter 1: Listening in

The house was quiet, a deep Sunday quiet. Terence sat on the couch, a book open but unread on his lap.His gaze was fixed on the hallway that led to the bedroom. The door was closed.But he knew they were in there.

Katie had kissed his forehead an hour ago, her purple hair tickling his skin.“Erika’s coming over. We’re just gonna… hang out.” Her eyes had sparkled with a secret.“The door might be open. Or it might not. Just… live your day, okay?”

He’d nodded, a lump in his throat.“Okay.”

Now, he listened. The soft thrum of the space heater from their room.A muffled laugh, Katie’s, bright and clear even through the wall. Then silence.A deliberate, charged silence.He stood up.The book slid to the floor. He didn’t pick it up.His bare feet were silent on the polished floorboards. The hallway seemed longer, the door at the end a focal point.It was open.Just a crack. A sliver of golden light from the floor lamp spilled onto the runner rug.

He stopped a few feet away.His heart was a drum in his ears.He could hear his own breath. This was invited.This was allowed.The thought did nothing to calm the electric jitter in his nerves.

A sound.A soft, wet sound of a kiss breaking. Then Erika’s voice, low and intimate.“Your lips taste like that wine. The one from last night.”

Katie’s answer, a whisper he had to strain to catch. “You’re stealing all the flavor.”

“Mmm. Let me get it back for you.”

Then a shift, the creak of the bedframe.A sigh.Katie’s sigh.Long and happy and unabashed.

Terence leaned his shoulder against the cool wall.He closed his eyes. The image was there immediately, painted by sound: Katie on the lavender sheets, her shirt off maybe, the warm light on her skin. Erika above her, that curtain of brown hair falling around them as they kissed.Another sound. A sharp, pleased gasp from Katie. “God, your hands are cold.”

Erika’s laugh, a puff of air.“Sorry. Warm them up for me.”

The quiet that followed was different.Thick.Full of movement he couldn’t see.Rustling fabric. The soft, rhythmic whisper of skin on skin.A bitten-off moan, stifled in a pillow.

Terence’s jeans felt tight.He was hard, achingly so. His palm pressed flat against the wall, anchoring himself.This was the line. He could stay here, just here, and it would be enough.It would be so much. He could drink in the sounds, let the heat pool in his gut, imagine the rest.

He could drink in the sounds, let the heat pool in his gut, imagine the rest. The quiet gasp became a sustained, shuddering moan from Katie, followed by Erika’s low, approving hum and the slick, rhythmic sound of their fingers working within each other, a secret cadence beneath their ragged breath and the wet, open-mouthed kisses that sounded like starvation and feast all at once.

Terence’s own hand moved, unbidden, to press against the hard line of his cock through his jeans, the pressure a blunt, frustrating echo of what he heard; he fumbled with the button of his jeans, finally freeing himself, his fist closing around his heated skin in time with the escalating pace from the room, his own breath becoming a ragged counterpart to theirs, each of Erika’s sharp, bitten-off curses—“Fuck, Katie, right there”—spiking through him like a current until the world narrowed to the wall against his shoulder.
