Chapter 3: The Conversation

Incest Sex Story: Chapter 3: The Conversation - A young man comes home from his first year of college to find that his family's changed... a lot. As the summer progresses, he gets a strange summer job and faces some big fears with the support of his parents and siblings. Note: has quite a lot of partner-sharing (swinging).

The drive home was a blur. My hands gripped the steering wheel tight, my mind replaying everything that had just happened. I’d fucked my sister-in-law. Watched my brother fuck his teenage daughters. I’d done my first double penetration while multiple family members encouraged me.

And the weirdest part? It had been a hell of a lot of fun. Natural, even.

The house was dark and quiet when I got back. Mia and Lily stayed at David’s, the girls overjoyed to be back in their own beds, if they were ever going to make it to them. Everything had all happened so fast that I was positively grateful for the alone time.

I took a long shower, letting the hot water pound against my shoulders. My cock was sore, my legs were tired, but I felt more inspired than I had in months. Like I’d discovered something I didn’t know I’d been missing.

But as I lay in bed that night, staring at the ceiling, the questions started coming.

How long had this been going on? Mia had said just a few years for her parents, and Lily only a few months, but what did that mean exactly? And who else was involved?

I thought about my parents. How would I feel if I found out they were involved? Mom and Dad were in their fifties, still in decent shape. Not just decent, I thought with loving appreciation, my mom had always been drop dead fucking gorgeous. Dad was half-retired at this point. Mom was a school principal. The nest was about to be emptied. Were they fucking other people? Fucking others in the family?

Then there was my older sister, Jessica. Nine years younger than David, she was twenty-three, just married to some guy named Tom, and lived less than an hour away. Did she know about David’s whole lovenest? Was she like him?

And my younger sister, Emma. She was only fifteen, halfway through high school. Surely she wasn’t—

No. I couldn’t think about that. Not yet.


The next morning, I woke up late, groggy and disoriented. The house still felt too quiet. I made coffee and sat at the kitchen table, trying to figure out what I was supposed to do with all of this.

Around noon, I heard a car pull up outside. Footsteps on the porch, then a key in the lock. The door opened, and Marcus walked in carrying groceries and a deli lunch, with Mia right behind him.

“Morning, sleeping beauty,” Mia said cheerfully. She wore cutoff denim shorts and a tank top, her bra visible through the thin fabric today. Progress, I guess.

“We brought food,” Marcus added, setting the bags on the counter. He was in basketball shorts and a t-shirt, looking relaxed and comfortable. “Mia said you didn’t have any time to go shopping. What with all the fucking going on and all, so Mom made us go shopping for you. Figured you’d also probably have questions.”

“Questions,” I repeated. “Yeah. You could say that.”

Mia started unpacking groceries while Marcus dropped some deli foods on the counter. I didn’t realize how hungry I was, it looked delicious. They moved around the kitchen like they owned the place, totally at ease. I just watched, still trying to process.

“So,” Marcus said, cracking a beer even though it wasn’t even one o’clock, but he did grab a glass and split it between the three of us. “What do you want to know?”

“Everything,” I said. “How did this start? When? Why?”

Marcus and Mia exchanged a look. Then Marcus sat down across from me at the table while Mia leaned against the counter. He stuck a fork in some cucumber salad and held it up and started explaining.

“Okay,” Marcus said. “So it started about three years ago. Dad got that new job at this investment firm downtown. Blackwood Capital. You heard of it?”

I shook my head.

“Not surprised. They’re pretty secretive. Anyway, Dad got hired as a senior analyst or whatever. Good pay, great benefits. But the culture there is ... different.”

“Different how?”

He waved at himself and Mia, and by extension the rest of his family — Which I guess included me, now — as if to say “us having all this sex with each other is how different, dude”. Then he took a bite of the salad.

“They’re really progressive about sex,” Mia spoke up between her own bites. “Like, really progressive. The executives are all involved in this lifestyle where they swap partners, have group sex, all that stuff. They believe it builds trust and loyalty or something.”

“That sounds insane, but you know, I always kind of suspected that sort of thing ... with the rich executive set?” I said, chuckling.

Marcus shrugged. “Clearly it works for them. The company does really well, everyone makes bank, and they’re all happy. So when Dad joined, somehow they had sniffed out what he was open to ... and they introduced him to it. Slowly at first. Company parties where things got explicit.”

“And he was into it?”

“Dad? Ohyeah. Mom too. I guess they’ve had an open marriage over the years.” Marcus took a drink. “But here’s where it gets interesting. One of the executives — guy named Richard Chen — he’s really into the whole family dynamic. Like, his wife and kids are all involved.”

“Kids?” My stomach clenched.

“Adult kids,” Mia clarified quickly. “His daughters are like twenty-two and twenty-four. But yeah, they all ... participate together. And Richard subtly let Dad know that the people who go furthest in the company are the ones who embrace the lifestyle fully. And who like to share their family.”

“So Mom and Dad decided to bring us in,” Marcus finished. “When Mia and I turned seventeen, they sat us down and explained everything. Asked if I wanted to go to parties and fuck some of the wives and daughters.”

“And you said yes?” I asked.

“I mean I am a horny, desperate kid,” Marcus admitted. “I’d sneaked a peek at my mom when I could. But then I went to one of the parties — just to see what it was about — and...” He grinned. “It was hot. Really hot. All these successful, attractive people, just enjoying themselves. No judgement, no drama. Just fucking and having fun.”

“So you told them you were down.”

“Yeah. I went home, thought about Mia here ... and even Lily. I mean ... you’ve been fucking them, so you know ... how crazy would I have to have been to pass that up?” He kind of blushed and waved me off, even though I wasn’t going to say a thing. “I know, I know ... Clearly I’m a big fucking pervert, from a family of perverts, duh. But ... I swear, the family vibe has improved like a thousand fucking percent. Not just at the parties, but at home too. It made everything more ... open. Honest.”

Mia moved to sit on the table beside us. “So when they sat us down, they asked me too. By that point, I’d already guessed that they’d been enjoying some strange. I’d overhear things. I was curious.” She smiled. “With their help, Marcus and I shared our first time. It was actually really sweet.”

Marcus laughed and blushed a little. “Awww, sis... “ The twins could be pretty cute together, I couldn’t help but imagine it.

“And Lily?” I asked.

“She literally begged to join when she turned fifteen,” Mia said. “She’d been listening to us for months, getting more and more frustrated. Finally, Mom and Dad decided it was okay. She’s mature for her age.”

“I mean yeah, I guess she’s a mature fifteen.”

“Almost sixteen,” Mia corrected. “Her birthday’s in a month and a half. But yeah, she’s young. Everyone is careful with her, makes sure she’s comfortable and safe. It’s not like she’s being forced or anything.”

I rubbed my face. This was a lot to take in.

“So this investment firm,” I said. “They just ... encourage incest?”

“Not just incest,” Marcus said. “But yeah, that’s part of it. They believe sharing between families makes the loyalty stronger. Maybe like the eskimos? And honestly, once you get past the taboo part, it kind of makes sense. You’re already appreciative and reliant on these people. Why not be free and easy with your loved ones with them too?”

“And other people at the firm do this?”

“Most of them,” Mia said. “Not everyone—some people keep it to just swinging with non-family. But a lot of them have brought in their kids, siblings, whatever. It’s more common than you’d think.”

“Speaking of which,” Marcus said, “The party this weekend. Big company thing at Richard Chen’s mansion. Everyone wears masks for privacy, but it’s basically a giant excuse to hook up. Dad can get you on the list. He and Mom think you should come.”

“To some hedonistic, eyes-wide-shut, rich person orgy.”

“Just to a fun, fun-and-games party ... seriously, Ethan!” Mia laughed, not disagreeing but trying to put me at ease. “Where there happens to be sex. But also food, drinks, fucking around, and, well, literal fucking around. It’s all pretty chill, but I’ve only been to a couple.”

“I didn’t say I didn’t WANT to go to a hedonist rich person orgy,” I smiled, chuckling.

“Well then lock it in,” Marcus said. “It’s totally up to you. But it could be fun. And you’d get to see the whole thing — understand where this all came from.”

Mia had been quiet for a moment, but now she slid off the table and moved behind my chair. Her hands went to my shoulders, massaging gently.

“What if I told you...” she said, “That I, personally, would really love for you to come. And to come meet some of the other folks.”

Her hands moved down my chest, and I felt her press against my back. Marcus watched with an amused expression.

“Mia,” I started.

“Shh,” she whispered. “Just relax.”

Her hands slid lower, over my stomach, then to the waistband of my shorts. She unbuttoned them slowly, and I didn’t stop her. Marcus was still sitting across from us, completely unbothered.

“You getting hard, uncle Ethan?” Mia asked, her hand slipping into my shorts.

I was. Of course I was.

She pulled my cock out, stroking it slowly. “You’re such a convinceable hunk,” she murmured. “And I love how nice and thick you are.”

Marcus stood up and moved closer. He pulled off his shirt, revealing his toned torso, then pushed down his basketball shorts. His cock was already half-hard, growing fuller as he watched Mia stroke me.

“Don’t be shy,” Mia said to Marcus, waving him closer. “Couple of gladiators like you two aren’t too cool to knock helmets every now and then, right?”

He moved to stand beside my chair. Mia’s other hand wrapped around his cock, and now she was stroking both of us simultaneously. Her small hands moved in tandem, and both Marcus and I groaned.

“This is crazy,” I muttered.

“Stop thinking,” Mia said. She moved around to kneel in front of us, looking up with those dark eyes. “Just feel.”

She leaned forward and licked the head of my cock, then turned and did the same to Marcus. Back and forth, teasing us both, her tongue swirling around our sensitive heads.

“Fuck,” Marcus breathed. “That feels good.”

Mia took my cock into her mouth, sucking hard while her hand kept stroking Marcus. Then she switched, taking Marcus’s cock deep while jerking me. She alternated between us, moaning like she loved every second of it.

“So where was I?” Marcus said, his voice strained. “Oh yeah. The ... oh fuck ... parties. They happen like, once every month or so. Big events. Maybe only half the people who show up are from the firm.”

Mia pulled off his cock with a wet pop. “And it’s not just fucking,” she added, stroking us both. “There’s amazing food, fun drinks. And you never know ... might meet a new cute somebody or make a good job connection?”

She took my cock back into her mouth, going deeper this time. I felt the head hit the back of her throat, and she swallowed around me. My hands gripped the chair arms.

“It’s so hilarious how you’re still trying to convince me,” I smiled, “while you’ve got my cock in your mouth.”

“The masks are cool,” Marcus continued, like his twin sister wasn’t currently deepthroating me and giving him a handjob. “Helps you feel safe about it, like you might worry about meeting someone who would recognize you. And in a way, they help you feel more free to do what you want, and who you want. You can be as wild as you want to be. Do whatever you want.”

Mia pulled off and licked up Marcus’s shaft. “Plus the mansion is gorgeous. Pool, hot tubs, tons of rooms. Very fancy.”

“How are you both just ... talking about this?” I gasped.

“Practice,” they said in unison, then laughed.

Mia stood up and pulled off her tank top and bra. Her small breasts bounced free, nipples already hard. She shimmied out of her shorts and panties, showing off her bare pussy. Then she sat on the table, spreading her legs.

“Keep selling him on it,” she said to Marcus, her fingers going to her pussy. “I think it’s just making him hornier, and that’s making me horny.”

Marcus moved closer to her, his hand joining hers between her legs. His fingers slid into her pussy while she rubbed her clit. She moaned and leaned back on one hand.

“The first party Dad took us to was intense,” Marcus said, fingering his sister. “Must’ve been like sixty people there. Some from the company, some from their families. Everyone, you know, REALLY enjoying themselves.”

“Everywhere you looked, people were fucking,” Mia added breathlessly. “In the pool, on the lawn, in bedrooms. It was like something out of a movie.”

I stood up and moved closer, my cock throbbing. Mia reached out and grabbed it, pulling me to her. She guided my cock to her entrance, and I pushed inside between Marcus’s fingers into her tight pussy with a groan.

“Yes,” she gasped. “Fuck me while Marcus plays with my clit.”

I started thrusting while Marcus’s fingers worked her clit. She was so wet, he was smearing it out from between us, and then he reached up and stuck his wet fingers in Mia’s mouth. Then Marcus leaned down and sucked her nipple while fingering her mouth, and Mia moaned loudly.

“The best part,” Marcus said against her breast, “is that no one judges. You can try anything. Be with anyone. It’s total freedom.”

“And everyone’s so nice,” Mia panted, her mouth now free of Marcus’s sex-wet fingers. “So ... Fuck! ... welcoming. They want you to feel good.”

That’s when we heard the front door open.

I froze mid-thrust, my cock buried in Mia. Marcus pulled back from her breast. We all looked toward the living room as footsteps approached.

“Hello?” a female voice called out. “Anyone home? I saw cars —”

My aunt Linda appeared in the kitchen doorway and stopped dead. Her eyes went wide, her mouth falling open as she took in the scene: me with my cock inside Mia, Marcus naked beside us groping her face, all of us frozen.

“What the FUCK is going on here?” Linda shouted.

Linda was my uncle’s wife — my dad’s sister-in-law. She was in her early forties, Korean-American, with long black hair and a fit body from her jogging obsession. She wore workout clothes that hugged her curves.

“Aunt Linda,” I started, pulling out of Mia quickly, wetness splattering against our naked thighs. “This isn’t —”

“Isn’t what? Isn’t you fucking your teenage niece in your parent’s fucking kitchen?” Her face was in a massive grimace. “I came to drop off some mail and I find THIS?”

“Mom, relax,” another voice said.
