Jon had always liked his sister-in-law, Mia. She was funny, kind, and always brought life into the house whenever she visited. But when she showed up on their doorstep with a suitcase, red-eyed and muttering about “another stupid fight” with her boyfriend Derek, he knew things were about to get complicated.

His wife, Sarah, had immediately pulled Mia into a hug. “Stay as long as you need,” she said, shooting Jon a look for affirmation.

He was unsure, but happy to comply with Sarah’s wishes. For three days, he tiptoed around the extra tension in the house, listening to Mia vent over wine, pretending not to notice when she cried during rom-coms. But nothing could have prepared him for the incident.

It was Saturday morning, and Sarah had left early for yoga. Jon, half-asleep, shuffled to the bathroom, pushing the door open without thinking. The steam hit him first. Then the sound of the shower running. And then–

Mia screamed.

Jon’s brain short-circuited. He spun around so fast he nearly slipped. “Oh my God–Mia–I’m so sorry, I didn’t know you were in here!”

The shower curtain yanked shut. “Jon?”

He practically lunged for the door, slamming it behind him, heart pounding. This couldn’t be happening.

Ten agonizing minutes later, Mia emerged, wrapped in a towel, her face bright red. They stood in the hallway, avoiding eye contact.

“I, uh… Sarah usually showers first,” Jon blurted, as if that explained anything.

Mia crossed her arms. “She left. I thought you knew.”

“I didn’t. Sorry. You have similar bodies. Not that I saw anything!”

This was somewhat true, but the younger sister certainly spent more time at the gym, as evidenced by her big, round ass.

A beat of silence. Then, unexpectedly, Mia spoke. “This is so awkward.”

Jon exhaled, rubbing his face. “Understatement of the year.”

She shook her head, a reluctant smile tugging at her lips. “Look, you saw me naked – it’s only fair I see you right? Deal?”

“I was thinking–maybe we should just shower together and get it over with,” she said as she dropped her towel to the floor.

Jon was unsure; he knew girls talked, maybe Sarah had told her about his small penis. It was clear that she was unsatisfied in the bedroom, and the sisters were close.

“I’m not sure, I have a problem.”

“Do you mean your small dick? Sarah’s told me all about it.”

“Ok…yes, that. Thanks for the brutal honesty.”

“No…I mean, I have a confession to make. I love small dicks. They’re pretty, and I’m quite small and tight…down there,” pointing to her shaved mound.

“You do?”

“Yes, Sarah has always been a size-queen, but I’ve only been able to get off using very small dildos. I want to worship your small penis, Jon.”

Jon had a new problem now – he was getting hard.

“Ok, I’ll let you look at it, but this is a one-time thing,” said Jon, pulling down his shorts.

“Oh, Jon – what a perfect little guy! So cute. And…he seems pleased to see me.”

Jon had barely noticed, but he was fully erect.

“You’re very beautiful, and your ass is unearthly, Mia.”

Mia turned to show it off. “Thank you – I work hard at the gym. Would you like to lather it up in the shower?”

“Listen… Sarah and I we’ve been going through a tough patch. But I can’t cheat on her.”

“Oh, please – she’s sucked every horse cock in town. Have you not noticed how much badminton she’s been playing?” Mia said, giggling.

“I…I have my suspicions. But still… ”

Jon lay stiffly in bed that night, staring at the ceiling while Sarah scrolled through her phone beside him.

Sarah yawned, rolling onto her side. “You okay? You’re all tense.”

No. I’m a terrible person. We’re terrible people.

“How long do you think Mia will stay?” Jon lied.

Jon’s question hung in the air, heavy with everything he wasn’t saying. Sarah set her phone down with a quiet click.

“Hard to say,” she murmured, tracing the edge of her pillowcase. “Mia and Elliott are having…well, sexual problems.”

“How so?”

“Well, Elliott’s… er… he’s very well hung…and well she doesn’t like it…can’t handle it,” she snorted

“Bigger than me then?”

“Darling, everyone’s bigger than you,” giggling and turning over.

“Goodnight, sweetie!”

“Goodnight, Sarah.”

Chapter 2: Size Queen

The next day, Sarah was up early for work.

“See you later – remember it’s Badminton tonight, so I’ll be back late.”

Jon stood frozen in the kitchen, coffee mug halfway to his lips. Across the counter, Mia slowly lowered her toast. A glob of strawberry jam plopped onto her plate.

Neither spoke.

The grandfather clock in the hallway ticked loudly. One. Two. Three.

Mia cleared her throat. “So. We’ve got… what, eight hours?”

Jon’s grip on his mug tightened. “Seven and a half. If traffic’s bad.”

A beat. Then Mia smirked. “Plenty of time to…” She trailed off, letting the implication hang.

“I have a few errands to run.”

This was dangerous.

This was stupid.

This was inevitable.

And they had 7.5 hours left…

The detour to Mia’s ex’s apartment was supposed to be quick–just grab the last of her things, in and out. But as Jon pulled up to the curb, Mia’s sharp inhale cut through the car like a shard of glass.

Sarah’s Prius was parked in Derek’s driveway.

Jon killed the engine. The silence was deafening.

Mia’s fingers dug into her knees. “Maybe she’s… helping him pack my stuff?”

Neither believed it.

Jon’s phone buzzed. A text from Sarah: “Running late, don’t wait up!”

The timestamp was from twenty minutes ago.

Mia let out a wet laugh. “Guess we know why she’s been so chill about me staying with you.”

Jon’s grip on the steering wheel turned his knuckles white. He’d been drowning in guilt since yesterday over thoughts, while Sarah had been–

Mia’s hand suddenly gripped his arm. “I have a backdoor key.”

Jon blinked. “What?”

“That little brick by the AC unit,” she said, eyes glinting with something fierce. “Let’s go see the truth for ourselves.”

For a heartbeat, Jon hesitated. Then he killed the engine.

They moved like shadows through the side yard. Mia’s fingers found the loose brick with practiced ease, pulling out a tarnished key. The back door opened with barely a sound.

The scene in the living room froze them both:

Derek was sitting on the couch with Sarah on her knees between his legs.

Aghast, Jon watched as Sarah’s mouth worked up and down Derek’s impressive cock.

“Sarah!”

“Jon!!” Sarah was still gripping Derek’s cock, but made eye contact with Jon.

“Oh my God–”

Derek jumped up. “What the hell–”

Jon saw red. He took one step forward–

But Mia was faster.

She strode to the bookshelf, grabbed a framed photo of herself with Derek, and smashed it against the wall. Glass rained down as she plucked their picture from the wreckage.

“Here’s your closure,” she said, voice steady as steel. She pocketed the photo and turned to Sarah. “And you? You’re dead to me.”

Sarah reached out. “Mia, please–”

Mia dodged her touch as it burned. She looked at Jon, her eyes asking a silent question.

He answered by taking her hand. Together, they walked out, leaving the door wide open behind them.

Chapter 3: I Want To Cum On Your Little Dick

The front door clicked shut behind them, sealing them in the quiet of the house. Mia leaned back against the wall, her fingers still trembling from what they’d seen. Jon stood frozen in the entryway, the weight of everything unsaid pressing down on them both.

Mia exhaled shakily. “I should pack my things.”

Jon’s head snapped up. “What? No.”

“I can’t stay here, Jon. Not after–”

“You can,” he said, stepping closer. “This is your home too.”

The air between them crackled. Mia’s breath hitched as Jon reached out, his thumb brushing away a tear she hadn’t realized had fallen.

“You don’t have to leave,” he murmured.

“Jon…I need to be held.”

The kiss was soft at first–a question, a test. But when Jon’s arms wrapped around her, pulling her flush against him, it deepened into something desperate. Mia’s fingers tangled in his hair as his hands traced the curve of her waist, mapping her like he was memorizing her.

“Jon, I want you inside me.”

Jon, now emboldened by proof of Sarah’s infidelity, unzipped his trousers.

“It’s so cute!” Mia reached out and used a finger to rub Jon’s nub gently

Jon’s cock responded and reached its maximum three-inch length. “Oh fuck! Mia”

Mia dropped to her knees and started gently sucking the head of Jon’s microphallus.

“It’s beautiful, so small and suckable”.

Mia continued giving Jon the most intense and intimate blowjob of his life.

“Take me to bed and fuck me, Jon!”

This was special. Jon carefully removed Mia’s clothes and led her by the hand to the bedroom.

He gently nuzzled her perky tits and kissed her nipples. Mia responded with gentle sighs.

“Please, Jon.”

Mia was spread on the bed, her little wet hole ready.

Jon gently maneuvered his little dick into Mia’s wetness.

Slowly, he thrust in and out, keeping a steady rhythm.

“Oh fuck, your cute little guy is perfect! You’re hitting my clit perfectly.”

“Fuck Jon – I can’t hold back. Please, can I cum on your small dick?”

“Cum for me, Mia.”

“Fuuuuucccckkkk!!!!!” The most powerful orgasm of her life washed through Mia.

“Can I cum inside you, Mia?”

“Yes, fill me up, Jon.”

Mia pulled Jon close as he came, warm jets of cum filled her Pussy.

As they lay on the bed in post-coital bliss, Mia turned to Jon.

“Thanks for making me cum – no man has ever done that before.”

“No woman has ever made me feel as wanted.”

Chapter 4: New Sensations

The key turned in the lock at 2:17 AM.

Mia stiffened in Jon’s arms, her fingers digging into his bare shoulder. They’d fallen asleep tangled together on the couch, the glow of some forgotten movie still flickering across their skin.

Footsteps in the hallway.

Sarah’s voice, sharp with false cheer: “You guys still up–”

The words died as she rounded the corner.

Jon sat up slowly, pulling the blanket higher over Mia’s bare legs. The silence stretched, thick with everything that needed to be said.

Sarah’s purse hit the floor with a thud. “Are you kidding me?”

Mia stood, the blanket pooling around her waist. “We saw you at Derek’s.”

Sarah’s face went pale, then flushed. “So you fucked my husband? That’s your grand revenge?”

Jon stood, positioning himself slightly in front of Mia. “Ex-husband. And we didn’t plan this.”

“Bullshit.” Sarah’s laugh was jagged. “All those looks. All those touches.” She advanced on Mia. “You’ve wanted him since the day you met him.”

Mia didn’t deny it. “And you? When did you start wanting Derek? Before or after you arranged our breakup?”

Sarah’s mouth opened, then closed. The truth hung between them, ugly and undeniable.

Jon picked up Sarah’s suitcase from where it sat by the door–still packed from her supposed “business trip.” He set it at her feet.

“You should go.”

Sarah stared at them–at Mia’s tousled hair, at Jon’s protective stance, at the love bites peeking above the blanket. Something in her face crumpled.

“You’ll regret this,” she whispered.

Mia reached for Jon’s hand. “No,” she said softly. “We really won’t.”

The door slammed on Sarah’s exit. The framed photo on the wall rattled.

Jon exhaled shakily. “Well. That happened.”

Mia turned to him, her eyes bright with tears and something like hope. “Now what?”

Jon kissed her, slow and sweet. “Now we live.”

Outside, a car engine roared to life.

Neither of them looked away from each other long enough to watch it leave.

“Jon, I love you – let’s go back to bed.”

Holding hands, they fell on the bed.

Mia’s amazing ass was in the air as she buried her face in the pillow.

“Take me this way.”

“Fuck Mia – your ass is perfect.”

“Would you like to do something very special?”

“What?”

“Take my anal virginity.”

“I’d love to, Mia.”

Jon knelt and started gently tonguing Mia’s asshole.

Mia responded by backing into Jon’s face, enjoying the new sensations.

“That feels amazing, Jon!”

Jon didn’t want to stop exploring Mia’s asshole, but the thought of taking her anal virginity was overwhelming.

“Are you ready, Mia?”

“Yes! Yes – take my ass!”

Jon steadied himself and slowly pushed the head of his tiny dick into Mia’s ass.

“Is this ok?”

Mia turned around to make eye contact with Jon.

“It’s perfect. Having your small cock in my ass is wonderful.”

Jon slowly thrusted in and out; Mia gave Jon little sighs of encouragement.

“Mia, I want to fill your ass with cum – is that ok?”

“Fill me, Jon. Pump me full of your seed.”

As Jon came, he reached over and kissed Mia.

The End.
