I sat at my laptop Wednesday afternoon, staring at the Blackwood Capital website for the third time that day. The homepage was sleek and professional—all glass and steel architecture photos, diverse stock images of people in business casual, corporate speak about “innovative investment strategies” and “community-focused growth.”
But when I clicked through to the “About Us” section, I got vague descriptions of “comprehensive wealth management” and “strategic consulting partnerships.” No specifics. No details about what they actually did.
The “Careers” page was even more frustrating: Blackwood Capital values discretion and cultural alignment. We recruit exclusively through internal referrals. For employment inquiries, please contact your network representative.
No job postings. No application portal. Nothing.
I switched to Glassdoor, hoping for more information. Only nine reviews total, which seemed impossible for a company that supposedly employed a hundred or two people. And every review was weirdly similar:
“Incredible company culture. Very unique environment. Not for everyone but if you fit, it’s amazing. 5/5 stars.”
“Best workplace I’ve ever experienced. The openness and collaboration is unlike anywhere else. 5/5 stars.”
“Progressive policies and exceptional benefits. You need to be comfortable with the culture but if you are, you’ll thrive. 5/5 stars.”
One lukewarm review stood out: “Interesting place. Very social. Can feel exclusionary if you don’t participate in all the events. 3/5 stars.”
That was it. Nothing about actual job responsibilities, salary ranges, or career progression. Just cryptic praise for “culture” and “fit.”
I closed my laptop and leaned back in my chair. It had been in the back of my mind for a while now to get some sort of summer job in order to start Sophomore year with a bit of spending money. Given my limited timeframe, chasing up something at Blackwood was a rational step, even if I had my misgivings. It was either that or wear the paper hat at Burger Mart, so why not find out directly what it was all about? If I was going to be part of this world — really part of it — shouldn’t I understand where it all started? See the source?
But there was no way to apply. No information. Nothing.
I grabbed my phone and texted David:
Can I come by and ask you about Blackwood? Trying to figure out if I want to get a summer job there.
His reply came within seconds
Come over now if you want. Perfect timing actually.
Twenty minutes later I was pulling into David’s driveway. The house looked completely normal from the outside — well-maintained suburban home, nice lawn, basketball hoop over the garage. The kind of place where families had weekend barbecues and neighbors borrowed cups of sugar.
But I knew what happened inside now.
I knocked and heard footsteps approaching. Sofia opened the door, looking stunning in her usual workout clothes. Her dark hair was pulled back, and she had a gym bag over her shoulder.
“Ethan! Hi, honey.” She kissed my cheek. “David’s inside with the girls. I’m heading to the gym but I’ll be back for dinner. Please stay, it’ll give me an excuse to put in a bit of effort!”
“No problem. Thanks, Sofia.”
She gave me a knowing smile. “Have fun. David could probably use the help.”
She headed to her car, and I stepped inside, closing the door behind me. I could hear a television playing from the living room — but also some high-pitched whimpering.
When I walked into the living room, I stopped and just stared.
David was kneeling behind the couch, wearing an open shirt and boxer shorts. Lily was lying upside down on the couch in front of her father, her butt perched over the lip, her sundress bunched up around her waist. David’s face was buried between her thighs, clearly eating her pussy.
Mia sat in the armchair across from them, completely naked, her legs draped over the armrests. Her small breasts were flushed, her nipples hard. She had two fingers buried in her bare pussy, working them in and out slowly while dividing her attention watching an old sitcom and watching her dad eat out her sister.
“Oh fuck, Dad,” Lily moaned, her hands gripping his hair. “Right there, don’t stop.”
Mia caught my movement and her face split into a wide grin. “Oh thank God!” she cried. “Daddy is getting tired out.”
David lifted his head briefly, his face shiny with Lily’s juices. “You insult my stamina, my dear.” Then he looked at me, and he did have quite a relieved look on his face, but he nonetheless dutifully dove back in, his tongue working Lily’s clit as she squirmed and swore.
My cock immediately started hardening in my jeans. “I can come back later if —”
“Don’t you dare,” Mia said, her fingers still moving. “Get over here. Dad’s been at this for like half an hour and we need more.”
“More?” I asked, moving closer.
“More attention,” Lily gasped. “He’s amazing but there’s two of us and one of him. We’re greedy.”
David pulled back again, wiping his mouth. “What she means is, these two have been horny all afternoon and I’ve been doing my best to keep up. But I’m one man.” He grinned. “Want to help your brother out?”
I looked at Mia, who was now rubbing her mound in massaging circles while maintaining eye contact with me. “I think I can manage that.”
I pulled my shirt off and kicked off my shoes. Mia beckoned me, and I immediately walked around the couch towards her, and she displayed her naked body to me with confidence and delight. I pressed against her and kissed her deeply, she responded by pushing her tongue into my mouth.
“Mmm, you taste good,” she murmured, unbuckling my belt. “Let’s get you naked.”
Within seconds she had my jeans and boxers around my ankles. My cock sprang free, already fully hard from seeing what I’d walked in on.
“Damn,” Mia said appreciatively, wrapping her hand around my shaft. “Always so ready.”
She pulled me over by my cock to the couch where Lily was still upside down and spread out, David still working between her legs. Mia climbed onto the couch and straddled Lily’s face, lowering her pussy to her sister’s mouth.
“Eat me while Dad eats you,” Mia instructed.
Lily laughed and sputtered against her thighs, muttering something about how her blood was already rushing to her head, but her sister clearly didn’t care. Like father duty, like sister duty. They’re a generous family.
She put her tongue immediately to work on Mia’s pussy, and Mia moaned. I stood there, my cock in my hand, watching this incredibly hot scene — my brother eating out one daughter while she was eating out the other.
“Closer than that,” Mia said to me, beckoning.
I moved closer, and she grabbed the back of my neck and started kissing me. Lily must have spied my approach despite having a sexy teenage badonk straddling her face, so she reached over to grasp my cock without preamble. Her fingers wrapped around me and caressed a bit, and then she reached up to her mouth and lubed them up with her saliva and Mia’s grool before wrapping them back around and stroking. I groaned and put my hand on Mia’s breast, and she reached down and joined Lily on my shaft, pussywet fingers sliding and twisting me. It felt decadent and heavenly.
Within five minutes of walking into my brother’s house, and here we were: David eating Lily, Lily eating Mia, both of them masturbating my cock. All of us connected in this chain of pleasure.
“So,” David said, pulling back from Lily’s pussy, replacing his tongue with massaging (and probing) fingers. Another gasping squeal from Lily, muffled by Mia’s thighs. “ ... You wanted to talk about Blackwood?”
I almost laughed at the absurdity. “Yeah. I can’t find any information about a possible summer job. The website is useless.”
“That’s intentional,” David said. He curled the two fingers in Lily’s pussy, making her moan into Mia’s cunt. “Everything’s referral only. They don’t want random people applying.”
Mia pulled me up to sit at the top of the couch next to Lily’s left knee. She shivered a bit as her sister nudged at a particularly sensitive spot, and then dropped her mouth around my cock and started throating me. I saw her almond eyes flutter up at me from under her lids in that sexy way she knew would get to me. My cock throbbed in her mouth. Jesus.
“Why not?” I gasped out.
“Control,” David explained, still fingering Lily. “They only want people who already understand the culture. Or who can be brought into it properly through someone they trust.”
“So how do I get a job?” I asked, groaning as Mia pulled off of me and began slathering along the sides, cradling my balls. I was slightly relieved, I had been worried that if Lily managed to dig into her older sister at just the right spot, I would have felt some teeth.
“I recommend you to HR and drop a note to Patricia Chen,” David said. “Her people will probably want to interview you first. Make sure you’re committed. Then you start.”
Lily’s back arched as David’s fingers worked her g-spot. “Oh fuck, oh fuck, I’m close!”
“Not yet,” David said, pulling his fingers out. “Let’s switch things up.”
He stood up and finally pulled his boxers and shirt all the way off. His cock was thick and hard and clearly ready, no matter what possible work it had been put to already. Mia climbed off Lily’s face and positioned herself on her hands and knees.
“Yayyy, Daddy got hard again,” Mia cooed, looking back at him. “I need your cock, Dad. It was my turn, remember?” She waved her little booty at us.
David moved behind her and pushed into her pussy in one smooth thrust. He gave her ass a little spank, too, followed by a squeezing grip. Mia cried out in pleasure, her back arching.
“Ethan, take Lily,” David instructed, like we were discussing a work project. “She’s so wet she’s dripping.”
I looked at Lily, who was indeed glistening between her thighs. She’d managed to turn herself around, and spread her legs wider in invitation, patting that fuzzy little mound of hers. Unlike Mia’s efforts of a slutty look, Lily chose to offer me a more babyfaced pout that absolutely screamed “fuck my little girl pussy uncle Ethan” like a page straight out of some dirty japanese manga.
Well, that’s an irresistible temptation if there ever was one, so I positioned myself between the thighs that she was pulling back against her as tightly as possible in order to gape herself before me. When I pushed into her tight pussy, we both groaned.
“Yes you fucking bastard,” Lily gasped. “Fuck me so goddamn fucking hard. Ram it into me, please.” Jesus. The mouth on this fifteen-year-old. I wondered if David’s whole family watched a lot of porn together.
Regardless, there we were — me fucking Lily while David was fucking Mia, both of us on the same couch, the girls moaning beneath us.
“What kind of work would I be doing?” I asked, thrusting into Lily steadily.
David laughed at the question while pounding Mia, who was grunting and clutching at the couch. The loud SLAP SLAP SLAP of his doggystyling mingled into the conversation. “Probably general office work at first. Filing, data entry, assisting with projects. Most of what goes on there under the whealing and dealing is standard business paperworky stuff.”
“Then what makes it different?” I asked.
“Well, it’s fucking Blackwood,” Mia gasped from in front of her father. “You’ll probably see people fucking everywhere. In offices, conference rooms, break rooms. It’s just normal.”
Wait, was she just making a joke about it? Or dead serious? I couldn’t tell. “Woah. For real?”
“How normal?” Lily asked, similarly confused, but also very clearly annoyed at my paused fucking while I was trying to sort out if Mia actually knew anything or was having me on. She reached around me and pulled me into her by my ass, “Lock in, Ethan. Come on.” I shook it off and started sliding out and back in, taking a slower pace.
“Like, you might be in a meeting discussing quarterly reports and two people start fucking on the table,” David explained. “And everyone just continues the meeting.”
I thrust harder into Lily, watching my cock slide in and out of her young pussy. “That doesn’t seem distracting?”
“You get used to it,” He continued. “And honestly, it reduces stress. People are happier. Productivity is actually higher because everyone genuinely wants to be there.”
“What about harassment?” I asked. “Like, how do you prevent that?”
“Consent is very closely guarded and a crucial fixture of the culture,” David said. He pulled out of Mia and gestured for us to switch. “Come on, swap.”
I pulled out of Lily reluctantly and moved to Mia. David moved to Lily. We pushed into our new partners simultaneously, and both girls moaned.
“Consent is the foundation,” David continued once he was buried in Lily. “You can proposition anyone, but no means no. Always. Richard’s very strict about that.”
“Has anyone gotten fired for crossing lines?” Mia asked, rocking back against my cock.
“Oh yeah, that’s happened a bunch,” David said. “It ended up pushing the company to be less discrete about their values in the face of any fallout.”
I fucked Mia harder, my hands gripping her small waist. “What about the pay?”
“Very good,” David said. “Richard pays well above market rate. He knows he’s asking for something unconventional, so he compensates accordingly.”
“How much are we talking?” I asked.
David named a figure that made my eyes widen. That was way more than I’d expected for hourly Summer work.
“Holy shit,” I said.
“Yeah,” David agreed. “The money is definitely a perk. Plus benefits, networking opportunities, all of that.”
“What’s the downside?” Lily asked breathlessly.
Mia started orgasming beneath me, letting out little panting shrieks, I felt her pussy flush with wetness as she clutched her legs, shaking and shivering. I tried to maintain my pace through it all
“Once you’re in, you’re in,” David said seriously, still fucking Lily. “It’s hard to leave. Not impossible, but your professional reputation becomes tied to Blackwood. That can complicate things if you ever want to work somewhere normal.”
I thought about that while slowing a bit with Mia. She was still having a few aftershivers. My own cock was throbbing, getting close.
“Are you going to cum?” Mia asked, sensing it.
“Getting close,” I admitted.
“Pull out,” she said. “I want to see it.”
I pulled out and Mia immediately turned around, kneeling on the couch. Lily joined her, both girls side by side, mouths open, waiting.
“Fuck,” I groaned, stroking myself. “That’s so hot.”
David blinked a bit at having Lily move off of him so fast but soon moved beside me, both of us jerking our cocks over his girls. They playfully shoved back and forth to get more in front of us, and stuck their tongues out, eyes blinking up. They knew what they were doing.
“You should work there,” David said casually while stroking himself. “I think you’d be good at it.”
“Yeah?” I gasped, my orgasm building.
“Yeah. You fit the culture. You’re smart, personable, and clearly committed to the funtime shenanigans.”
That pushed me over the edge. I came hard, shooting ropes of cum onto Mia’s face and Lily’s breasts. Beside me, David groaned and came too, covering Lily’s face and Mia’s chest.
When we finished, both girls were dripping with our cum. They immediately started kissing each other, sharing it, their tongues visible as they licked it off each other’s faces and bodies.
“Jesus Christ,” I breathed, watching them.
“They’re insatiable,” David said affectionately. “Always have been.”
The girls finished cleaning each other and curled up on the couch together, satisfied for the moment. David and I pulled our clothes back on and moved to the kitchen.
“I’ll call the HR rep tomorrow,” David said, grabbing beers from the fridge. “That’s Patricia, Richard’s wife, she’s an excellent people-reader. She’ll probably want to meet you for coffee or something. Just be honest about what you’re looking for.”
“What should I say I’m looking for?”
“Experience in the business world. Networking. And be upfront about understanding the culture. She’ll appreciate the honesty.”
We heard footsteps and turned to see Mia and Lily coming into the kitchen, trying not to drip too much as they went for the stack of dishtowels.
“Are you staying for dinner?” Lily asked me, wiping herself down. “Mom texted, she gave up on making a whole dinner and is grabbing take-out on her way home.”
“Sure,” I said. “That sounds good.”
We got drinks and sat around the kitchen table talking about normal stuff — college, summer plans, what everyone was watching on TV. It was surreal how quickly we could shift from fucking to just hanging out like a regular family.
Sofia came home with some Mediterranean Dinner, and Marcus arrived shortly after with Keisha. We all ate together, laughing and joking, completely normal except for the fact that half an hour ago David and I had been fucking his daughters.
After dinner, as people were cleaning up, I pulled my nephew aside.
“Marcus,” I said, “Can I ask you a favor?”
“Sure, what’s up?”
“It’s Emma. She’s still figuring out her feelings about all this. She knows everything but she’s not sure if she wants to participate. I was thinking maybe you and Lily could come by tomorrow and talk to her? Give her the boy-girl perspective from people closer to her age?”
Marcus nodded thoughtfully. “Yeah, I can do that. Lily’s a good choice too. She’s only a smidge older than her, smart as hell about this, she’s kind of the best of us at being open about the experiences.”
“Thanks, man. I think it would help her to hear from you guys.”
“No problem. We’ll come by tomorrow afternoon.”
I got home around nine to find the living room lights on. Mom, Dad, and Emma were on the couch watching some action movie. But as I walked in, I realized Mom and Dad were definitely fucking.
Mom was spooning with Dad on the couch, her back to his chest, a blanket across both of them but Mom’s leg was up and she was writhing. The way the blanket was moving, the flush on Mom’s face, the slight rocking motion — they were absolutely having sex.
Emma lay chest-down on the couch extension, completely absorbed in the movie, scooping popcorn from a bowl in front of her. She didn’t seem bothered at all.
“Hey honey,” Mom said, slightly breathless. “How was David’s?”
“Good. Instructive.” I leaned down and kissed her cheek, then kissed Dad’s hair, then Emma’s. “What are we watching?”
“Some explosion movie,” Emma said, still focused on the screen. “It’s pretty good.”
From this angle I could see Mom’s face more clearly—the glazed look in her eyes, the way she bit her lip occasionally. Dad’s hands were under the blanket, clearly on her hips, guiding her movements.
They weren’t being terribly subtle about it, but it was definitely happening. And Emma either didn’t notice or didn’t care. And Emma. Stretched out on her stomach, little butt bursting out of her pajama shorts. A hint from the dark gap between.
I plopped down next to her and gave out a tired sigh, my back up against the couch where my Dad’s cock was right at this moment sliding in and out of my mother’s delicious-sounding pussy. There was a slight swaying to it. I had a lot on my mind and ran my hand over my face. As my fingers passed, I was once against staring at my little sister’s ass, and everything I could see between.
We watched the rest of the movie together. At some point Mom tensed and her breathing hitched — clearly cumming — but she didn’t make a sound. Just gripped the blanket tighter and rode it out.
When the movie ended, Emma stood and stretched. “I’m going to bed. G’night, everyone.”
“Night, sweetie,” Mom and Dad said in unison.
Emma headed upstairs, and once her door closed, Mom let out a long breath and climbed off Dad’s lap. The blanket fell away, revealing Dad’s softening cock, wet and glistening.
“Well can’t say I kept track of what was happening in the movie,” Mom said, laughing. “Trying to not cause too much of a ruckus.”
“You did great,” Dad said, cleaning himself up. “Very subtle.”
“Yeah, extreeeeemely subtle,” I said as sarcastically as I could.
“Emma knows what’s going on,” Mom said. “She’s just choosing not to engage. Which is healthy, actually. She’s setting her own boundaries.”
“Marcus and Lily are coming by tomorrow to talk to her,” I said. “I thought hearing from people her age might help.”
