Three days with Mia and Lily had scrambled my brain. We’d fucked in every room of the house — sometimes twice. My cock was sore, my balls were drained, and my sense of right and wrong had taken a serious beating. But the girls kept insisting everything would make sense once I met the rest of the family.

Which is how I ended up in my car Saturday afternoon, driving to my brother David’s place in the suburbs, my stomach doing flips.

“Just be cool,” Mia said from the passenger seat. She wore actual clothes today — jean shorts and a crop top — though I knew she wasn’t wearing a bra. Lily sat in the back in a sundress, her legs crossed in a way that let me see her crotch in the rearview mirror whenever I glanced back. Cheeky.

“I’m cool,” I lied.

“You look like you’re gonna puke,” Lily observed.

“I’m not gonna puke.”

“Just remember,” Mia said, “Mom and Dad know about us. They’re happy about it.”

“That’s not reassuring.”

She laughed and put her hand on my thigh. “It’ll be fine. You’ll see.”

David’s house was nice — not fancy, but solid. He’d done well for himself since he’d gotten the new job at the firm. His wife Sofia answered the door, and I tried not to stare.

I’d seen Sofia at family gatherings before, but I’d never really looked at her with the thought of having sex with her in mind. She was late thirties, Latina, with dark hair pulled back in a ponytail that kept a few sassy curls framing her brow. She wore tight jeans that hugged her curves and a loose jersey that showed off toned arms. Her breasts were medium-sized, nice but not huge. But her ass — God, her ass was fucking incredible. Tight but round, the kind that made any pair of tight pants look like they’d been invented specifically for her.

“Ethan!” She pulled me into a hug that pressed me against her chest, then held me by my forearms and looked at me. “It’s so good to see you, manito. Come in, come in.”

“Thanks, Sofia.” I tried to keep my eyes on her face.

“Your brother’s in the kitchen. Marcus and Keisha are around somewhere.” She leaned in conspiratorially, and I caught just a light whiff of perfume — had she fancied up for me? “The girls told me you’ve been having fun this week.”

My face burned. “I ... uh...”

She laughed and patted my chest. “Relax. Get used to that kind of teasing.”

The house smelled like someone was grilling. I followed Sofia through to the kitchen where David was pulling beers from the fridge. My oldest brother was in his mid thirties - my mother’s teen pregnancy - solid build from years of physical work, just starting to show some gray in his dark hair.

“Little bro!” He handed me a beer and pulled me into a one-armed hug. “How’s college treating you?”

“Good. Pretty good.” I took a long drink.

“Bet it is,” he said with a knowing grin. “Mia and Lily been taking care of you?”

I choked on my beer. David laughed and rubbed my shoulder affectionately.

“I’m just teasin’ you, buddy. I know, I know ... I love you, man. You know that what’s mine is yours...” He glanced at Sofia, who’d pressed up against the counter beside him. His other hand wrapped around her and he squeezed. “Uhh not that any of these ladies are anyone’s. Right, babe?”

“We’re just so happy that you’re sharing this love with us,” Sofia agreed, her eyes big and emotional, leaning into him.

Before I could process that, footsteps came down the stairs. A young guy appeared — Mia’s twin Marcus, my nephew. He was seventeen like her, tall and athletic with his dad’s build and his mom’s coloring. Mixed heritage that gave him this striking look. He wore basketball shorts and a sleeveless T that showed off defined arms.

“Hey, Uncle Ethan,” he said with a grin. “Didn’t know you were coming by.”

“It was an invitation I couldn’t ignore,” I managed. He was grinning and searching my face, amused at my discomfort.

“Cool, cool.” Marcus grabbed a soda from the fridge. “Keisha’s here too. She’s getting dressed.”

As if on cue, a girl came down the stairs. Keisha was eighteen, Black, with natural hair pulled up in a puff. She was gorgeous—athletic build, long legs, curves in all the right places. She wore a sundress similar to Lily’s, and I couldn’t help noticing how it hugged her body.

“Oh hey,” she said when she saw me. “You must be Ethan. I’ve heard a lot about you.”

“All good things, I hope,” I said automatically.

She smiled, and there was something knowing in it. “From the girls. They’ve, uh, been eager for you to get back in town.”

Mia and Lily had disappeared somewhere, leaving me at the mercy of the rest of the family. And once I finally got over all the teasing, the conversation flowed easily enough — college, work, summer plans — but there was an undercurrent I couldn’t quite name. The way Sofia kept touching David. How Marcus’s hand would rest on Keisha’s thigh. The looks they all exchanged.

When dinner was ready, we ate outside on the deck. The food was good — David had grilled chicken and corn, and I was starting to relax a bit. Maybe this was all in my head. Maybe it was just a super rare, private thing. Maybe the girls had been exaggerating.

Then Sofia leaned across the table to grab the salad, and her jersey gaped open. I could see straight down to her breasts — she wasn’t wearing a bra either. She caught me looking and smiled but didn’t adjust her shirt.

“So Ethan,” she said, settling back in her seat, “the girls tell me you’re home for the whole summer.”

“Yeah, that’s the plan.”

“Good. We should all hang out more.” Her foot touched mine under the table. “Get to know each other better.”

I glanced at David, but he was just eating, unbothered.

“That’d be nice,” I said carefully.

Mia appeared at my elbow with more beer. “You doing okay?” she whispered.

“I don’t know what I’m doing,” I whispered back.

She squeezed my shoulder. “Just roll with it.”

The rest of the table heard everything, their grins positively feral.

After dinner, everyone migrated inside to the living room. David put on some music. Not too loud, just background noise. Marcus and Keisha took the loveseat, sitting close. My brother David sprawled on one end of the couch. Mia and Lily sat on the floor by the coffee table. I took the armchair, trying to look casual.

“Anyone want drinks?” Sofia asked, still bustling about a bit. “I’m making margaritas.”

“Hell yes,” Lily said.

“You’re fifteen,” I said automatically.

Everyone laughed. “Oh, Ethan,” Sofia said, patting my head as she passed. “You’re so cute.”

She made a pitcher of margaritas, and soon everyone had a glass. The alcohol helped me relax a bit more. The conversation got looser, funnier. Marcus told a story about something dumb that happened at school. Keisha had everyone laughing with her impression of her boss at the ice cream shop where she worked.

I noticed Marcus’s hand had moved higher on Keisha’s thigh. She didn’t seem bothered—in fact, she shifted to give him better access. But what really shook me was seeing David’s hand under his wife’s tank top, clearly cupping her breast. Sofia just leaned into him, sipping her drink.

“This is nice,” Sofia said contentedly. “All of us together. Having you around more.”

“Yeah,” Mia agreed. She was sitting between Marcus’s legs now, leaning back against the couple. When had that happened? “Housesitting’s been fun, but it’s good to be home.”

Lily had pulled herself up on the other side of David. David like her Dad (my brother) David. She perched on the couch armrest, her knees pressed against his other side. His free hand — the one not on Sofia — now rested on Lily’s thigh, fingers tracing patterns on her skin.

My cock stirred in my shorts. Was something starting to happen? My heart started to beat and I could feel my throat tighten. This was actually happening.

“You know what we should do?” Keisha said suddenly. She stood up, swaying slightly — the margarita hitting her. “We should play a game.”

“What kind of game?” Marcus asked, grinning up at her.

“Truth or dare? Strip poker?” She laughed. “I don’t know. Something fun.”

“Or,” Mia said, “we could just ... not play games.”

The room went quiet. Everyone looked at Mia, then at me.

“What do you mean?” I asked, though her intentions were clear, I just had to hear it.

“I mean,” Mia said, standing up, “we could stop pretending this is just a boring family evening. We could actually do what we all want to do.”

My heart hammered. “Which is?”

Sofia laughed softly. “Oh, honey. You know what.”

And then she stood up and pulled that loose team jersey in one smooth motion. Mia and Lilly’s mom, my sister-in-law, right in front of us. Her breasts were perfect: medium-sized with dark nipples, sitting high and firm despite her age. She wore no bra, and now she was topless in the living room like it was the most natural thing in the world.

“Anyone else hot?” she asked, smirking.

My brother pulled his shirt off. Marcus did too, revealing his athletic torso. Keisha bit her lip, watching.

“Come on,” Mia encouraged. She pulled off her crop top, baring her small breasts. “Everyone join in.”

Lily stood and unzipped her dress, letting it pool at her feet. She was completely naked underneath, her young body on full display.

I sat frozen in the armchair, my cock now fully hard and tenting my pants.

“Your turn, Keisha,” Sofia said with a smile.

Keisha looked nervous but excited. She moved to the center of the room, and Marcus used the remote to turn up the music slightly. Then she started to dance.

It wasn’t professional or anything, but it was sexy as hell. She swayed her hips, running her hands over her body. Slowly, she reached down and grabbed the hem of her sundress, pulling it up inch by inch. She revealed her thighs first—smooth and toned. Then higher, showing she wore lacy black panties. Higher still, and the dress came off over her head.

Her body was incredible. Athletic and curvy, with full C-cup breasts held in a matching black bra, a toned stomach, and those gorgeous legs. She reached back and unclasped her bra, letting it fall. Her breasts bounced free—dark nipples, full and heavy.

“Yeah, baby,” Marcus breathed, a huge grin on his face.

Keisha hooked her thumbs in her panties and turned around, bending over as she slid them down. Her ass was perfect—round and firm. When she straightened and turned back around, she was completely naked. Her pussy was lightly trimmed, revealing lips puffy and already glistening.

“Better?” she asked with a grin.

Marcus stood up and pulled down his shorts and boxers in one motion. His cock sprang free—thick and hard, a good seven inches. He didn’t seem embarrassed at all.

“Much better,” he said, pulling Keisha against him. They kissed, deep and hungry, his hands roaming across her ass, gripping and pulling.

David stood too, stripping naked. His cock was similar to Marcus’s—thick and hard. Sofia immediately reached up and wrapped her hand around it, stroking slowly.

“Ethaaaan,” Sofia teased, looking at me with dark eyes. “You’re overdressed.”

“I...” I glanced at Mia and Lily. They were both naked now too, watching eagerly.

“Come on,” Sofia said, releasing her husband. She walked over to me, those incredible hips swaying. She straddled my lap in the armchair, her naked body pressing against me. “Let me help you.”

Her hands went to my shirt, pulling it up. I raised my arms automatically, and she tossed it aside. Then her hands went to my pants, unbuttoning them.

“Oh jeez, Sofia...” I started. I couldn’t help but look over at David.

“Shh.” She lifted us up enough to pull my pants and briefs down. My cock sprang free, and she made an appreciative sound. “Very nice.”

She wrapped her hand around my shaft, stroking. Behind her, I could see Marcus pulling Keisha back onto the loveseat. He’d sat down, and she was straddling him, grinding her pussy against his cock. They were kissing frantically, hands everywhere.

David was bending Lily over the arm of the couch she was on. He was leaning over her from behind, his hands running across her skin, and he was kissing her neck. Mia knelt beside them, watching.

“Jesus, you guys ... this is crazy,” I muttered.

“This is our family,” Sofia corrected. She reached between us and rubbed my cock through her pussylips, getting herself positioned. “Now stop thinking and let’s just fuck, young man.”

She sank down on me in one smooth motion.

I groaned. Her pussy was tight and hot, gripping my shaft perfectly. She was so wet I slid in easily, and when she bottomed out, I was completely buried in my brother’s wife.

“Oh fuck,” Sofia moaned. “Now that’s a lovely young cock.”

She started riding me, lifting up and dropping down, taking me deep each time. Her breasts bounced in my face, and I couldn’t help it — I leaned forward and sucked a nipple into my mouth.

“Yes,” she gasped. “Just like that.”

Across the room, Marcus had flipped Keisha around on the loveseat, spreading her onto her back as he ground himself on top of her. I watched him rub his cock up and down her beautiful brown pussy as he groaned in anticipation.

“Stop teasing me and fuck me already,” she hissed at him, and I watched him slide his thick shaft one more time through her furrow before he sunk it deep into her. They both moaned loudly.

“That’s it, baby,” Marcus encouraged. “Take all of it.”

Keisha’s gorgeous breasts began circling wildly as he started to ram into her again and again. Marcus grabbed them, squeezing and pinching her nipples. She threw her head back and moaned.

On the couch, David had pushed into his youngest daughter. She was bent over the arm, and he was fucking her from behind with steady strokes. Lily’s young face was flushed, her mouth open in pleasure.

“Harder, daddy,” she gasped. “Oh f-fuck ... Please, harder.”

He grabbed her hips and really started pounding into her. The sound of skin slapping skin filled the room, mixing with everyone’s moans. I couldn’t believe what I was watching, my brother David doing his own daughter doggy-style not six feet from where his wife was riding me.

Mia had moved to kneel beside her brother and Keisha. She reached between them and played with Keisha’s clit while Marcus fucked her. “You look so hot taking his cock,” Mia encouraged. “Does it feel good?”

“So good,” Keisha moaned. “S-so fucking good. Yes, rub me right there, Mia. Oh-h FUCK!”

Sofia was slamming down on me harder now, her pussy clenching around my shaft. “You like watching them?” she asked breathlessly. “Like seeing your family getting fucked?”

“Yes,” I admitted, unable to lie.

“Me too.” Sofia ground down on me, taking me deep. “It’s so hot. All of us together like this.”
