I stood there frozen for a moment, wondering where they’d disappeared to. Almost wondering if they had ever really been here. My heart pounded so hard I could feel it in my throat. Theye were definitely here. My mom and I had definitely seen each other. This was it. This was actually happening.
I started walking toward where they had been, weaving through naked bodies and ongoing sex scenes. A woman moaned nearby as a man bent her over a table. Two guys were double-penetrating someone in the hot tub. But no sign of Mom, Dad, or Linda.
“Ethan?”
I turned toward the familiar-sounding voice. A woman stood there—late twenties, wearing a short cocktail dress and a red mask. She had long brown hair, an athletic build, and curves in all the right places. I recognized enough of her for my brain to explode a bit.
“It’s me, you idiot,” she said with a laugh, pulling her mask up slightly.
Jessica. My older sister.
“Jess?” I stared at her. “What are you doing here?”
“What do you think, you dumbshit?” She laugher, gesturing around at the orgy. “Same thing as everyone else.”
Behind her, a tall guy appeared—broad-shouldered, dark hair, wearing slacks and a button-down with a mask. Tom, her husband. I’d only met him a couple times since they’d gotten married last year.
“Hey, Ethan,” Tom said easily, like we weren’t at a sex party. “Good to see you again.”
“Yeah, uh, you too.” I was still processing. Jessica knew about this? Jessica was part of this?
“We’re late,” Jessica explained. “Tom had to work. But we didn’t want to miss it entirely.” She looked me up and down, taking in my naked body and half-hard cock without any embarrassment. “Looks like you’ve been having fun.”
“I ... yeah. I guess.”
“You guess?” She laughed and stepped closer, her hand going to my chest. Her touch was casual but intimate. “Come on, little brother. You can’t tell me you’re not enjoying yourself.”
“It’s a lot to process,” I admitted.
“It is at first,” Tom agreed. He’d stripped off his shirt, revealing a fit torso. “But once you stop overthinking it, it’s amazing.”
Jessica’s hand slid down my stomach, getting dangerously close to my cock. “How long have you known? About all this?”
“Like a week,” I said. “Maybe a little more. Mia and Lily kind of ... introduced me.”
“Oh, those two are trouble,” Jessica said with a grin. Her fingers brushed against my cock, making it twitch. “Good trouble though. They know how to show someone a good time.”
“Jess,” I said, my voice strained.
“What?” She wrapped her hand around my shaft, stroking slowly. “We’re family. We’re supposed to be close.”
This was surreal. My older sister — who used to babysit me, who helped me with homework, who I’d looked up to growing up — was stroking my cock at an orgy.
“I’ve been part of this for about two years,” Jessica continued, her hand moving steadily. “Tom got recruited to the firm, and we got introduced to the lifestyle. It changed everything.”
“Changed it how?” I asked, trying to focus on the conversation despite what her hand was doing.
“Made us closer,” Tom said. He’d moved behind Jessica, his hands going to her hips. “Removed all the jealousy and possessiveness. We can enjoy other people and still love each other completely.”
“Plus the sex is incredible,” Jessica added. She released my cock and pulled her dress over her head in one smooth motion.
She was wearing nothing underneath. Her body was amazing—toned from regular gym sessions, with full C-cup breasts topped with pink nipples, a flat stomach, and curvy hips. Her pussy was neatly trimmed, just a small strip of hair above her slit.
“Damn, Jess,” I breathed.
“What? You’ve never thought about your sister naked?” She posed playfully, hands on her hips. “Because I’ve definitely thought about you. Especially since I heard you were home for summer.”
My cock was fully hard again now, and she noticed with a satisfied smile.
Tom had stripped down too. His body was solid—not as cut as Marcus but strong and capable. His cock was thick and long, maybe seven inches, already hard from watching his wife.
“Keisha!” Tom called out suddenly.
I turned to see Keisha nearby—she’d been talking with some other guests but perked up at her name. She was still naked and gorgeous, her body glistening with sweat and cum from earlier activities.
“Hey Tom,” she said, moving over to us. “Good to see you.”
“You too.” Tom pulled her into a kiss immediately, his hands groping her ass. “Want to play?”
“Always,” Keisha said with a grin.
Tom looked at me and Jessica. “You two catch up. I’m going to borrow Keisha for a bit.”
He led Keisha to a nearby lounge chair, and she immediately dropped to her knees in front of him. Her hands wrapped around his thick cock, and she started licking up the shaft while looking up at him.
“She’s so good at that,” Jessica said appreciatively, watching. “Tom loves her mouth.”
We stood there watching as Keisha took Tom’s cock into her mouth, sinking down until her lips met the base. Tom groaned and put his hand on her head, guiding her as she bobbed on his shaft.
“So,” Jessica said, her hand finding my cock again, “how are you handling all this? Really?”
“I mean I’m having a blast,” I said. “But it’s intense. I don’t feel like I’ve really been processing any of it. Amazing but also kind of overwhelming.”
“That sounds about right.” She stroked me slowly while we watched Tom and Keisha. “It took me a month or two to really adjust. But once you do, you’ll never want to go back to normal life.”
Keisha had moved to licking Tom’s balls now while stroking his shaft. Her technique was practiced and skilled. Tom’s eyes were closed, his head tilted back in pleasure.
“Get up here,” Tom said to Keisha.
She stood, and he turned her around, bending her over the lounge chair. Her ass was perfect—round and firm — and when Tom spread her cheeks, we could see her pussy was already wet and ready.
Tom pushed into her in one smooth thrust, and Keisha moaned loudly. He started fucking her immediately with deep, hard strokes, his hips slapping against her ass.
“Fuck yes,” Keisha gasped. “Your cock feels so good.”
Jessica’s hand was still on my cock, stroking faster now as we watched her husband fuck Keisha. “You like watching?” she asked me.
“Yeah,” I admitted.
“Me too.” Jessica pressed against my side, her naked body warm against mine. “I love watching Tom with other women. Gets me so wet.”
I could believe it. Her free hand was pulling my hand between her own legs, and for the first time I was feeling my sister’s pussy, the soft curls of her pubic hair, the furrowed valley beneath, the moist wetness of her entrance.
Tom was really pounding Keisha now, his thick cock slamming into her pussy. Keisha’s breasts swung beneath her with each thrust, and her moans were getting louder and more desperate.
“That’s it, babe,” Jessica called out to Tom. “Fuck her hard. Make her scream.”
Tom grabbed Keisha’s hips harder and increased his pace. The wet slapping sounds mixed with Keisha’s cries of pleasure.
“I’m gonna cum,” Keisha gasped. “Oh fuck, I’m gonna cum!”
Her body went rigid, then started shaking as her orgasm hit. Tom kept fucking her through it, prolonging it, until she was a trembling mess.
Tom pulled out, his cock still hard and glistening with Keisha’s juices. He stroked himself a few times, and looked at us with a big grin of accomplishment, before surveying the rest of the crowd, as if looking for someone to conquer next.
“Fuck,” I groaned, watching. Jessica’s hand on my cock was doing the impossible — my cock had gotten fully erect once more.
“I’m sure you want to fuck,” Jessica said, releasing me. “But let’s save it, little bro.”
“Save it for what?”
She grinned. “For later. For when you really need it.”
Keisha wasn’t letting Tom go so easily, he’d grabbed his cock and pulled it into her mouth, savoring the taste of her own pussy juice on his shaft. Tom groaned at the sensation.
“Come on,” Jessica said, taking my hand. “Let’s walk around. I want to see who else is here.”
She led me through the party, both of us naked, passing by countless scenes of sex and pleasure. We stopped to watch a woman taking two cocks—one in her pussy, one in her mouth. We saw a group of five people all pleasuring each other in a tangle of limbs. We watched as someone got fucked in the pool while people cheered.
“Have you been with Mom yet?” Jessica asked casually as we walked.
The question caught me off guard. “No. I ... uh. I’ve seen her getting fucked, I think. She saw me.”
“Oh?” Jessica’s grin was all delighted mischief.
“I think she was almost beckoning me over? But then I lost track of her in the crowd.”
Jessica stopped and looked at me seriously. “Do you want to? Be with her?”
“I ... yeah. I think so. But it’s complicated.”
“It’s not as complicated as you think,” Jessica said. “She’s beautiful, she’s sexual, and she clearly wants you. What’s the problem?”
“She’s my mom.”
“So? I’m your sister.” Jessica pressed against me, her breasts against my chest, her hand wrapping around my cock again. “Does this feel wrong?”
“No,” I admitted. “But—”
She kissed me before I could finish. Her lips were soft and insistent, her tongue pushing into my mouth. I kissed back automatically, tasting her, feeling her naked body against mine.
When she pulled back, we were both breathing hard.
“See?” she said. “Not wrong. Just different. Just ... family.”
Before I could respond, someone grabbed my arm. I turned to find Mia, naked and flushed from recent activity.
“There you are,” she said. “I need you. Now.”
“I’m kind of—”
“No, seriously.” She pulled me away from Jessica. “Dad wants to try something and we need another guy.”
I looked back at Jessica apologetically. She just laughed and waved me off. “Go. We’ll catch up later.”
Mia dragged me across the patio to where David and Sofia were with another couple I didn’t recognize. The woman was maybe thirty, Asian, with an incredible body—big breasts, tiny waist, curvy hips. The man was similar age, white, fit and tall.
“Ethan, perfect,” my brother said. “We want to try a train. You game?”
“Oh man,” I said, thinking about all the sex I’d already hard. But I looked down at my soldier. Still standing tall, thanks to Jessica.
“All the women lined up,” Sofia giggled at me. She was already positioning herself on her hands and knees, waving that amazing ass at me. “You guys just move down the line, fucking each of us in turn.”
The Asian woman got on her hands and knees beside Sofia. Then Mia joined them. Three women, asses up, pussies on display and ready.
“Holy shit,” I muttered.
David and the other man were already positioning themselves. David pushed into Sofia’s pussy while the stranger entered the Asian woman. That left Mia for me.
I knelt behind my niece and pushed into her tight, familiar pussy. She moaned and pushed back against me.
“That’s it,” David said. “Now we rotate. Fuck them for a bit, then move to the next one.”
I fucked Mia with steady strokes, watching my cock disappear into her young pussy. After maybe twenty thrusts, David called out “Switch!”
We all moved to our right. Now I was behind Sofia, my sister-in-law. Her pussy was stretched from David’s cock, wet and ready. I pushed inside easily, and she moaned.
“Fuck yes, Ethan,” she gasped. “Give me that young cock.”
I fucked her hard, gripping her amazing ass, watching it jiggle with each thrust. Then we switched again, and I was behind the Asian woman whose name I didn’t even know.
Her pussy was nicely tight, gripping my cock in a warm embrace. “Oh god,” she moaned. “Always nice to meet a new fella.”
We continued rotating, each of us fucking all three women multiple times. The rhythm was intoxicating—never quite getting used to one pussy before moving to the next. Each woman felt different, sounded different, and moved different.
“I’m getting close,” David announced after we’d been at it for maybe ten minutes.
“Me too,” the other man said.
“Pull out and cum on them,” David instructed. “Cover all three.”
We fucked a few more strokes, then all pulled out and positioned ourselves over the three women. They turned around, giggling like porn stars, and crouched in front of us, tongues out and eyelashes fluttering.
I stroked myself hard and fast, outrageously turned on by the sight of such indulgent fucksluts. I came all over Mia’s face, thick ropes of cum coating her skin while she giggled and flinched. Beside me, David was covering Sofia, and the stranger was cumming on his wife.
When we finished, all three women were dripping with cum. They immediately started licking it off each other, sharing it in messy kisses and giggles.
I collapsed onto a lounge chair, completely spent. My cock was exhausted, my legs were shaking, and I was pretty sure I had nothing left to give. That was it, I was done.
Tom appeared beside me, also looking satisfied. “Hell of a party,” he said.
“Yeah,” I agreed. “But I think I’m heading home, before I’m sucked completely dry.”
“Aw, headed home already, bud? ... David!” Jessica also appeared, having caught up to us after some of her own socializing. “I see you’ve been playing trains with our little brother.” She pretended to pull a hornwire. “Choo-choooooo! Tom will be sad he missed out.”
Tom was next to me, looking at his niece and his sister-in-law and the other woman, still giggling and playing with the results of the bukkake, his own cock in his hand, still hard and strong.
“Aw man...” he moped. “I bet that was fun.”
Jessica leaned down and kissed my cheek. “You should come over for dinner next week. We’ll invite some of our friends. Low-key, no pressure.”
“Your friends are part of this too?” I asked.
