Mark slammed the Uber door. He picked up his trolley and swung his laptop bag on his shoulder as he climbed the porch steps. So good to be back home after two days. These were two good days. The IPO was getting closer, which meant he was finally nearing paydirt after leaving the firm he had started with Tim. Tim had been disappointed that Mark had left their firm to report to someone else, but Galaxy Technologies, as that cliche goes, made him an offer he couldn’t refuse.

Two days on the road. Two days of VC pitches, customer handshakes, and controller meetings that dragged on forever. Two days of bad coffee and pretending to care.

And then there was Sarah. Filming another one of her “wellness sessions” with those two guys and Iman—the woman who’d reached out to set it all up. When he got the notification, he locked himself in an office and saw the preview with a low, simmering regret that he wasn’t there to record it himself.

At least he’d stopped by Mary’s. That helped.

Stopping by the door, he said, “Hey Siri, open the door.” Smart lock. Sarah’s idea. The lock opened, and he stepped into his house.

He dropped his bags near the stairs, removed his dress shoes, and went over to the kitchen. Taco night again. He saw his family making tacos with the tortillas, fajitas, vegetables, and sauces. And fried chicken. Yes, they had weird food combinations for dinner.

“—like the mitochondria are the powerhouse, but they never tell you it could be an alien!” Mark heard Lily’s voice carry from the dining room, always excited to discuss new sciency stuff.

His family was already seated around the table, fajitas almost done.

He took a few steps toward the dining room when Lily launched herself at him. “Daddddd!” Lily screamed. The scent of her perfume—Hermes, Sarah’s Hermes—came with a whiff, and Mark had to force himself not to inhale too deeply.

Mark’s hands found her bare waist on instinct as she hugged him, and her short top had ridden up. “Easy there, tiger.” He forced a chuckle. He was trying not to notice how her breasts pressed against him. “Miss me that much? I was just gone for two days.”

“Obviously.” She kissed his cheek again—a little longer. “We saved you the crispiest chicken skin pieces.”

“Liar.” Mark smiled at her and gave her ponytail a playful pull. “You ate them all, didn’t you?”

Lily’s giggle followed him into the dining room, where Sarah sat at the head of the table, wearing a low-cut dress. She knew Mark loved seeing her cleavage when he returned from trips, but today she wore it for an extra audience.

Jason barely glanced up from his tacos and chicken. Cutting pieces by knife, eating by hand, sauces dripping down... “Hey, Dad.” A glob of sour cream clung to his stubble. The kid is gross.

Emma met his eyes properly, her gaze sharp even through half-empty wine glasses. She was the only one allowed to drink alcohol since she was 22, but Mark had shared a beer with Jason as well. “How was New York?” Her own bare foot traced slow circles on Jason’s calf under the table.

Mark dropped into his usual seat beside Sarah. “Productive.” He accepted the plate Lily pushed toward him, heaped with chicken and a taco she had made for him.

“How was the flight?” Sarah asked, her bare foot brushing his ankle beneath the table. A secret hello.

“Late as usual, but it allowed for more time at Mary’s,” replied Mark.

Jason’s fork dropped, making a clanging noise. Emma looked at Sarah, trying to find some meaning in that sentence.

Lily took some Coke from the fridge and plopped into her chair with exaggerated noise. “Is Aunt Mary still doing those weird ‘holistic’ cleanses and, ugh, detoxificants?” Her knee bumped Mark’s thigh as she reached for the sour cream.

“Yes—she tried feeding that to me. I refused,” Mark chuckled, watching Sarah’s fingers tighten around her wine stem. Interesting. He leaned closer, kissing her cheeks and taking that opportunity to whisper. “Saw your latest upload. That reverse one with the...”

Sarah elbowed him sharply as Mark let out an “Owww.”

Emma sighed like the world’s most put-upon daughter. “Jesus, Dad. Gross. Some of us are eating.”

But her bare toes were now tracing Jason’s thigh beneath the tablecloth, through his shorts.

Lily, always the performer, launched into a story about school. “I don’t even want to go tomorrow,” she sighed, pouting extra for Mark. “Two of my teachers are out, so it’s just subs. The only real class is AP Bio, and I already finished the project with Stella.”

Sarah arched a brow. “You’re not skipping school, Lily.”

But Mark, ever the indulgent father, waved a hand. “She’s eighteen, babe. She knows what she’s doing.” Then smiled at Lily. Had she grown overnight?

Lily beamed, sticking her tongue out at Sarah, who rolled her eyes dramatically. Jason and Emma exchanged glances—how the fuck did Lily manage to pull that off? Emma thought, ‘Mom had never let me skip school. But then Mom was not fucking me then also’

Jason cleared his throat. “Unlike Lily, I don’t have the luxury of missing class. I’ve got a lab at eight.”

Emma nodded. “Me too. And I’ve got work. Depositions all morning.”

Sarah yawned and stretched, hands together, giving the effect that her breasts were almost coming out of her dress. “Elizabeth and I are doing brunch, then shopping for work.”

The reference to Elizabeth sent a ripple through the table. Elizabeth Callahan—Tim’s wife. The kids didn’t know the full extent of their parents’ relationship with the Callahans, but they knew enough.

Sarah’s phone buzzed with a series of texts from ‘The Corrupted Sinclairs’ group chat, a new group name for Mom and the siblings.

Emma: Liz—WTF?

Lily: Does she know?

Jason: Does she join?

Emma: You wish.

Lily: Is she straight?

Emma: And what stuff for work?

Sarah smirked as she put her phone away and then stood up abruptly.

“Emma, help with the dishes. Jason, your laundry’s still in the dryer. It doesn’t take 2 days to dry, you know...” She shot Mark a look. “And you need to shower. You smell like airport.”

Mark caught Lily’s wrist as she stood to go. “Since when do you wear your mom’s perfume?”

Lily leaned down until her lips brushed his ear. “Since I learned how much you like it.” Her pinky finger—innocent, delicate—traced the shell of his ear before she said, “G’night, Daddy, I mean Dad.”

Mark stared after her, then slowly got up to go, not knowing what to think.


Later, the kids were all gathered in front of their parents’ bedroom door, the siblings trying to listen to the sounds coming from inside and piece together what was going on. Emma had her cheek pressed against the door, trying to listen in. Jason, taller, had his ears above her head, and Emma could feel him breathing down her neck. Lily knelt beside them in her pajama shorts and tank top.

Then they heard Sarah’s moan—the same moan they had heard last night and this morning. The moan when Emma licked her, when Jason fucked her, and when Lily shared Jason’s cum with her. The moan that she made in her videos while being eaten. Clearly, Dad was having a feast.

“I saw that last scene,” he said, accompanied by a slurp. “You looked so fucking amazing taking those two cocks. And the way Iman sucked your pussy—fuck.”

Sarah’s breathy laugh and that moan. “I knew you’d watch. Iman was really talented. Fortunately, we connected through Feeld. And after Tim shut down the camera, we had more fun.”

The siblings looked at each other inquiringly. ‘Feeld?’. Emma resolved to look it up.

Mark’s voice dropped. “Tim told me. Did you enjoy it?”

Sarah: “Yes, but I missed you.”

Mark: “I missed you too. And the fun.”

Moan. Dad’s busy again—the kids heard only slurps and groans.

Then a big moan—evidently Mom is cumming, the siblings smiling at each other.

Some sounds of shifting, a popping sound

“Oh! Oh God—yes, suck me just like that.” Mark’s voice came through.

The gagging sounds that followed were obscenely familiar. Emma recognized them from how Mom sucked cock. Jason’s cock. Any cock.

The siblings exchanged smiling glances before slipping away. They were now aroused. But they didn’t want to risk it further by getting caught. If their plan worked, well, they wouldn’t have to be listening outside the bedroom.

They stopped in front of Lily’s room, which was across from Emma’s. Lily whispered. “Heading to bed. BIG day tomorrow.”

Then she looked at Jason’s erection bulging against his shorts and said, “Hoping it’s as big as Jay’s.”

Then she held a mock finger to Lily, “You better not wear him out.”

Emma replied coyly. “We’re doing nothing, Little One. Just going to sleep,” as she flashed her a V sign and air-kissed her to see Lily heading inside her room.


As soon as Lily disappeared into her room, Emma dragged Jason into hers, her fingers already working at his drawstrings.

“I need you inside me now,” she demanded, shoving him onto the bed. She shoved her t-shirt over her head and quickly removed her shorts. No panties. Jason laughed as he saw that.

Emma grinned. “Why waste extra clothes when we have to take them off? Besides, I like to have my girls breathe when I sleep.”

Jason removed his shorts to show his stiff cock. “Same, but boys.” He naturally jerked his cock and looked sheepishly at Emma.

Emma threw herself at him, burying her head in his neck and kissing him all over, and then pulling him to plant her lips on his. Jason had his hands on her breasts, squeezing them, a little rougher than he expected.

Emma almost ordered, “Enough talk. Need to fuck. Now!” She lay down, pulling him over her as his cock went in and he arched his back to put it to the hilt. It was as if Emma’s breath was being taken out as she felt Jason filling her up.

Jason looked at her intently with his cock in her pussy, but instead of moving, he asked, “You want Dad’s cock too, don’t you?”

Emma clenched around him, slowing her breath. “Fuck yes,” she admitted, rolling her hips, trying to urge him. But she could feel his insecurity.

‘Fuck, I hate being an elder sister when all I want to do is get fucked by my brother and his big cock,’ she thought to herself.

But to Jason, she smiled.

“But this cock?” She murmured, tightening her pussy around his cock slowly and deliberately, drawing a deep groan from his chest. “This one is mine. It’s special. We’re special.” Her voice was soft but certain.

That worked. Jason grinned and started moving. Oh, it was exquisite. Hard and fast, he banged into her. Not lovemaking. Just fucking. He wanted to be her hero, and in that moment, he was. It made Emma cum as she whimpered into his mouth. They switched positions, and he fucked her doggy style, with her face pressed in the pillow, and she played with her clit to cum again. Then she made him lie down and climbed on him. Fucking him this time. His hands clamped on her breasts, feeling her nipples in his palm, as Emma bounced on his cock. When she climaxed again, he came with her as she collapsed on him, shouting, “Jasssooooooon.”

Jason was ecstatic.

As she lay panting on him, Jason lifted her head to gaze at her eyes, his expression unreadable. “You really want Dad?”

Emma had to crush the jealousy coiling in Jason’s chest before it could spread—yet she also owed her brother the truth. She traced his lips, then, with all her will, she said simply, “Yes.”

“But I’ll never get tired of this cock.” She kissed him softly, tongue inside his mouth, idly biting his lower lip. “I love you.”

Jason’s face didn’t change. Emma feared that she’d blown in.

Then she saw him smile—slow, wicked, and purposeful. His cock was still inside her and was already showing signs of life.

Emma laughed, rolling her hips to encourage him to get harder.

“That’s why I’ll never change it for anything,” she murmured, riding him again. “It’s made to pleasure me again and again.”


Next Morning:

The Jura coffee machine was gurgling its last drops into Mark’s “World’s Okayest Dad” mug. Sarah had stirred his coffee when she had heard Mark coming down. She was popping a couple of pieces of bread in the toaster when Mark shuffled into the kitchen. Sarah was dressed in a low-cut blouse and a skirt that hugged her ass.

“Good morning, all,” taking a deep breath to smell the coffee.

“You’re late today.” Sarah winked at him.

“Jet lag,” Mark said sheepishly. “Oh, you look fine this morning,” leaning in for a kiss.

Jason and Emma groaned.

Then Mark looked around; he asked, “Where’s Lily? She’ll be late for school.” Mark asked, accepting the steaming mug Sarah handed him.

Sarah arched a brow. “Still in bed, courtesy of your little ‘She’s eighteen, babe. She knows what she’s doing’ speech last night.” She looked at Mark with mock indignation. “That girl could convince you to let her skydive without a parachute if she batted those eyelashes enough.”

Mark chuckled into his coffee. “She’s a good kid. And she’s on top of her studies.” He was clearly ogling her breasts now.

Emma rolled her eyes but smiled at Mark. “Of course, you let her skip. Meanwhile, in freshman year, you made me go to school with a 102 fever because ‘Sinclairs don’t take sick days.’”

Mark laughed, “You turned out ok. And I did not send you to school with a fever.”

Jason was laughing, snorting his Raisin Bran.

“Finish up, little brother. Need to leave in five, or you’ll be late for your 8 AM.”
