One evening, while they were eating, Finn told Rachel that his little brother Peter was coming to visit. Rachel, who had never met Peter, was thrilled. Finn explained that she shouldn't be surprised by his brother. He was quite the free spirit and very tactile. Rachel replied that if he was Finn's brother, he must be very kind and that there was no problem. The next evening, Rachel opened the front door of their apartment. Peter was on the other side. Rachel was surprised by Peter's physique. He was Finn's little brother, yet he was much more muscular. He didn't kiss her but gave Rachel a peck on the cheek, placing a hand on her shoulder. Finn, who was in the living room, went over to his brother, and they hugged. Peter complimented Finn on having such a pretty girlfriend. He leaned close to his brother's ear and asked him if she was good in bed. He steps aside, laughing, and tells his brother he hasn't changed. When Rachel walks past him, Peter scans her from head to toe. He thinks he'll soon be sleeping with her. The three sit down at the table, and the conversation is particularly pleasant. That same evening, while Rachel is in bed with Finn, she tells him that her little brother is charming. Finn replies that Peter is primarily a seducer. And that he has something that some women can't resist. Curious, Rachel asks him what it is. Finn finally tells her that he has a penis that is much larger than average. Rachel pretends not to care, but she feels quite aroused as she thinks about Peter's penis. All characters are over the age of 18.

Chapter 4: The Reckoning

The door clicked shut, the sound final and absurdly loud in the silent room. Rachel turned the lock, her fingers trembling. She stood there, her back pressed against the solid wood, as if it could shield her from what she’d just seen, from what she now was. The scent of Finn’s cologne on the blue bedspread was a gentle, mocking reminder of a simpler loyalty.

From the other side of the wall, a low murmur began.

She couldn’t see them now. The solid drywall was a barrier. But it was thin, cheap apartment drywall, and it transmitted sound with cruel clarity. She heard the girl’s voice, thin and breathless. “I can’t… Peter, I’m so sensitive. It’s too much.”

“It’s never too much,” came Peter’s reply, his voice a lazy, confident rumble. “You take it so well. I’m gonna flood that pretty pussy again. You’re gonna come for me one more time.”

A sharp, keening cry pierced the wall, followed by a series of shuddering gasps. Rachel closed her eyes, but the sound painted the picture in vivid, shameful detail: the girl convulsing beneath him, overwhelmed. It had been hours, she’d said. And yet, it wasn’t over.

Silence stretched for a minute, filled only with Rachel’s own ragged breathing. Then the rustle of sheets, a shift in weight.

“Clean it up,” Peter said, his tone casual, almost conversational.

There was a wet, slick sound, soft and intimate. Rachel’s mind supplied the image instantly: Peter lying back on the mussed sheets, the girl between his legs, her head bobbing. A hot wave of something forbidden swept through Rachel’s abdomen. She had never done that for Finn. The thought was a betrayal, a secret flare of curiosity in the dark.

Her hand moved of its own accord, sliding under her skirt. The fabric of her panties was damp. She pressed her palm against herself, a jolt of electric shame and desire shooting through her. She was listening. And she was getting wet.

“Good girl,” Peter’s voice filtered through, thick with approval. “Now, ride it. I want to watch you impale yourself. Take it all.”

A soft whimper, then the rhythmic creak of bed springs. A slow, deliberate cadence at first, then building. The girl’s moans were punctuated by deep, guttural exhales. “That’s it,” Peter murmured, a coach, a director. “Fuck yourself on me. Take every inch. You love how deep it goes, don’t you?”

Rachel’s fingers slipped beneath the waistband of her panties. She was slick, swollen. Her own touch was frantic, a poor imitation of the violence and command next door. She bit her lip hard, the pain a sharp counterpoint to the pleasure coiling tight in her gut. She moved closer to the wall, her ear almost touching the cool paint, as if proximity could pull her into the scene. With her free hand braced against the wall, she slid two fingers inside herself, her hips jerking in a feeble mirror of the rhythm she heard. The sounds from the other room—the slapping skin, the broken pleas, Peter’s filthy, praising commentary—wound her tighter and tighter until she broke, a silent, shuddering orgasm crashing through her. She stifled a cry against her own arm.

For a few blessed seconds, there was only the sound of her own pounding heart. Then the girl’s voice, small and uncertain. “Peter… I’ve never… not that way.”

His reply was immediate, devoid of hesitation. “There’s a first time for everything. Relax.”

A sharp, pained gasp was cut off, replaced by a low, continuous moan that bloomed into something else—shock, then a dizzying, surrendered pleasure.

He was in her ass.

The realization struck Rachel like a physical blow. She and Finn had never… it was a line they’d never discussed, a frontier in their tame, loving sex life. This was a violation, an invasion. It should have repulsed her.

Instead, a fresh, desperate heat flooded her. Her fingers, still wet from her own climax, found her clit again, circling with a frantic urgency. She was listening to a girl being taken in a way she herself had never experienced, by a man who was not her boyfriend, and it was the most arousing thing she had ever heard.

“Oh god… oh god, Peter…” the girl’s voice was a slurred chant of ecstasy.

“Told you you’d like it,” he grunted, his voice straining now with effort. “So tight. Taking it like a champ. My brother’s girl is going to love this.”

The words, meant for her, did it. They pushed her over the edge again. A second, more violent orgasm ripped through her, buckling her knees. She slid down the wall, a wet, trembling heap on the floor, the geometric pattern of Finn’s bedspread blurring before her eyes. She was panting, spent, overwhelmed by a pleasure so intense it felt like annihilation.

In the next room, the sounds gradually ceased. The bed creaked once more. Muffled movements. A soft, post-coital murmur she couldn’t decipher.

Then, silence.

Rachel lay on the floor for a long time, the cool hardwood against her cheek. The frantic energy drained away, leaving a hollow, aching shame. She had just masturbated to the sound of her boyfriend’s brother fucking another woman. She had come twice, vividly imagining herself in that woman’s place.

About twenty minutes later, she heard the distinct sounds of someone dressing. The quiet click of the guest room door opening. Footsteps in the hall, then the soft swish of the apartment’s front door closing.

They were gone.

The silence they left behind was absolute, and it echoed in the empty places inside her.
