Threesome with My Baby Sister Britney, and Her Young Neighbor Natalie

A dream encounter with my baby sister and her sweet young neighbor.

"Hey, Brit, you and Natalie sure have gotten big!"
I heard a loud scoff and Britney shouting. "THAT WAS FUCKING RUDE !! I'm not big, except for my tits !! And Natalie is fine as fuck !! How dare you, Mike !!"
I chuckled softly. "No, Hon. I'm not talking about physical appearance. I mean your stories on SexStories69. You two are the hottest things since sliced bread. Everybody loves you and wants to be in one of your stories. And Natalie... hot damn! What any man or woman would give to have a piece of that!"
Britney flashed a smirk. "Sexist pig !! It's all about fucking, isn't it ??"
I shot her a grin and pointed at my phone. "I mean, it's in the title of the website, Babe. Your stories are all about them. Every story on this site is manuscript porn. Don't be calling me out for the things you help contribute to. I'm just saying. Besides, as I was saying, you two pretty much own this site."
I saw a flash in her eyes, a sparkle as though she felt proud of her accomplishments. And why not? She worked really hard to turn out amazing stories, not only for others' reading pleasure, but for her own gratification. A queen of a sex story site in her own right, along with her gorgeous neighbor Natalie.
She padded over to me in her tight little cut white jean shorts and crop-top shirt tied in a knot between her breasts as her ponytail swung behind her, and leaned down over my shoulder, looking at my phone. I turned and glanced at her, catching a glimpse of her swollen breasts aching to spill out, and smelling her wonderful perfume that filled my senses. I quickly diverted my eyes back to my phone.
She exhaled a sexy little moan. "When you got it, you got it !!" She glanced at me and our eyes met, and for a split second I thought about kissing her. But it had been years of not having any luck in that area with her, how would she have responded?
She pulled back and went into the kitchen. I watched her perfect ass sway as it disappeared behind the counter, and I could feel my arousal growing. God, was she fucking sexy!
Without looking at me, I hear her call back over her shoulder. "I can feel your eyes on me, Mike !!" And she giggled, never skipping a beat as she began making herself some breakfast.
I laughed and hopped back on my phone, pretending to do whatever as I continued watching her do her thing. "I'm not paying any attention to you. I'm just looking up more stories to read." But she knew that was a lie, I'm sure.

A few hours later I had been alone in my room, masturbating to a story Natalie had written about her, her little sister, and helping her fuck a dog for the first time. I came hard as I imagined the entire scenario, with Natalie beneath her sister, lapping at her pussy as the dog came inside her. Fantastic story, you should go read it if you haven't.
I cleaned myself and headed for the bathroom. That's when I heard the shower running. I knocked on the door and peered in. "How long you gonna be, Brit?"
"Mike, get out !!"
"I gotta pee. How long are you going to be?" I could see a bit of her silhouette through the shower curtain, though I couldn't make out any detail. But I could imagine.
"Go outside. Give Natalie a good show, or something. I'm..." a small whimper escaped her lips, followed by an almost secretive moan. I only guessed that she must be using the shower head to make herself cum, and immediately got aroused again.
"Fine," I said, and left to head outside to relieve myself. I went out the back door and stuck my cock out of my boxers and took a piss, looking toward Natalie's house, wondering if she was in her room watching out her window. Of course I couldn't tell, but I had hoped.
When I was finished I tucked myself back inside my boxers and went back to the bathroom to listen in. Sure enough my senses were assaulted by the heavy, breathy moans and muffled screams as Britney was having an orgasm. I pulled my cock out as I listened in and began to jerk myself again. For the first time I was in the middle of it with my own sister, however minimal.
It wasn't long before I was matching her moans with my own movements, and I could feel my balls tightening. Come on, Brit, cum with big brother, I thought silently. A few minutes later I heard her scream "OH FUCK, YES !!" and I shot my load at the same time, a long, thick rope that sailed through the air and onto the bathroom floor.
I was about to go in and clean it up, but what if she caught me in there? What would she say? I hesitated and thought, maybe she won't notice. After all, it's off to the side, the door was only cracked a little bit. It wasn't fully open. I decided to quietly shut the door and return to my room.
A few minutes later I heard another shout. "WHAT THE FUCK ?? MIKE !!" Oh shit, I guess I should have risked cleaning it up. A few seconds later she burst into my room, wrapped in nothing but a towel. Her slender legs immediately caught my attention.
"You shouted?" I asked.
"WHEN YOU'RE DONE JERKING OFF TO YOUR SISTER IN THE FUCKING SHOWER, CLEAN UP YOUR DAMN MESS !! THAT'S GROSS !!" She was so sexy when she was angry.
"I would have if you hadn't found it," I grinned stupidly. "The truth is, I just didn't want you to catch me in there. I was hoping you wouldn't find it, and I would have cleaned it up after you were out."
She was still fuming, and her being naked with only a towel in my room as I was lying naked in my bed was turning me on again. Her eyes went wide as she saw the reaction she was having on me and she huffed.
"Oh, like you've never done anything with family before. Mom and dad, huh?"
"That's none of your concern !!!" I could see her eyes darting between my face and my cock, the slight hesitation in her eyes, the shift in her stance. Subtle, but I could sense the seed of desire beginning to grow.
"Just... clean it up next time !!" She turned and left, leaving me alone in my room again. Well, damn. I wish that had turned out differently. I got up and went to the bathroom to clean up my mess and take a shower.

As soon as I finished lathering up my hair and body, I heard the door open. She wasn't being sneaky about it. I grinned.
"Coming to get a second look?" I asked. She laughed. "As if, big brother !! Just checking to see if you did what you said !!" I opened the shower curtain and peered out at her...
And Natalie!
My face turned red. "Hi, Nat. What are you doing here?"
A smirk crossed her beautiful face. "I had to come see for myself. Britney told me all about it."
I felt like a schoolboy with a crush. "Well, sorry to burst your bubble, Hon, but I already cleaned it all up." I shot Britney a glance.
They both giggled. "Oh, not that, big brother !!" she said as they came into the bathroom.
Natalie licked her lips and looked in the general direction of where my cock might be behind the curtain. "I just want to see what it looks like, that's all." Her gorgeous eyes sparkled and I saw her tongue dart out and lick her lips quickly.
I suddenly felt very self conscious. Ever wonder what an animal in a zoo feels like? Yeah, me either. Until now!
"Come on, Mike !!" Britney said with a mischievous grin.
"Yeah, big guy, show me," Natalie chimed in. My heart started racing. I'd always had a major crush on her, and I couldn't believe this was happening. Was I being set up?
I swallowed and took a deep breath. "Show me your tits." I was talking to Natalie, but to my surprise they glanced at each other and both lifted their tops, revealing both sets of perfect, beautiful breasts! Instantly I got hard and pulled the curtain aside.
They were very different in build, and though Natalie was younger and legally untouchable, she was fucking hot as hell. I saw her eyes go wide and she began to squeeze her young breasts, pinching and tugging on her nipples.
"Mmmmm... you were right. That is delicious!"
Britney let out a sweet laugh that made my cock twitch with excitement. "I told you that you would like it !!"
I was both somewhat embarrassed, and fully turned on. The girls turned to each other with grins on their face and Britney pulled Natalie's head toward hers, kissing her, slipping her tongue into her mouth. Oh fuck, this was amazing! And it wasn't even my birthday. I slowly began to stroke myself.
After a moment of this they broke the kiss and looked at me. Britney slowly began removing her shirt, and Natalie followed suit. They both stood before me completely topless, Britney in her tight white cutoff jean shorts, Natalie in her oh so gracious black yoga pants with the word PINK written on the ass in white lettering.
Without taking her eyes off of me, Natalie said. "I kinda wanna join him right now, Brit."
Britney moved behind Natalie and began slipping her yoga pants off of her, slowly rolling them down her beautiful slender legs. My eyes widened at the sight of Natalie's bare little pussy coming into view. She wasn't wearing anything beneath her yoga pants. My cock stiffened even more.
Gingerly stepping out of her pants, Natalie turned and faced Britney and gave her another kiss before lowering herself to her knees and working her out of her tight white shorts. I heard Natalie moan as Britney's bare cunt came into view, and she couldn't resist giving it a nice long lick.
Britney closed her eyes and let her head fall back with a whispered moan. "Oh God !! Fuck yes, Natalie !!! Fuck, Baby !!" She grabbed Natalie's head and pushed her sweet pussy into Natalie's face while I watched open-mouthed, still stroking.
I didn't care that Natalie wasn't in the shower with me at that moment, this was the fucking hottest thing that's ever happened in front of me by far!
It's said that a girl knows a girl's body better than anyone, especially her own. I've never had any complaints, but it sure was amazing watching Natalie bring my sweet sister to orgasm as quick as she did. Britney pulled Natalie's face hard against her beautiful bare pussy and screamed "OH MY FUCKING GOD !!! NATALIE, BABE !!! FUCK YES !!!" as she let her juices splash all over her. Natalie hungrily lapped up everything Britney had to offer.
I was so fucking close, I had to stop. I didn't want to waste another drop, since I knew Natalie would be hopping in the shower with me. She stood up and kissed my sister hard and deep, allowing Britney to taste herself on her lips.
I groaned a little loud and they turned and looked at me. The two most beautiful picturesque girls I've ever laid eyes on looking at me with naughty little grins as they walked toward the shower.
I offered a hand to Natalie to help her in with me and she took it gingerly, stepping in beside me. She wrapped her arms around my waist and pulled herself tightly up against me, my cock pressing into her young slender body as I offered my hand to Britney and helped her inside as well.
It was a pretty tight fit with three people in the shower at the same time, but we made it work. Britney closed the curtain and then grabbed me by my hair and turned my face to her, looking deep into my eyes.
"Is this what you've always wanted, big brother ??" she asked me as she leaned in to kiss me. I slipped an arm around her waist and moaned into her mouth as our tongues met in a seductive dance of hunger.
Natalie reached down and wrapped her fingers around the base of my cock and slowly began to pump back and forth, which elicited an even hungrier moan into Britney's inviting mouth.
"Let me have a turn, Brit," Natalie said as she grabbed the back of my head and pulled my face to her. I grinned and our lips met in a hungry display of wanton desire. I shoved my tongue deep into her mouth as my heart beat rapidly in my chest.
Britney somehow managed to wigflw herself down on the floor of the shower between mine and Natalie's legs. "My turn, Nat !!" she exclaimed as she buried her face in her tender young pussy. Natalie whimpered into my mouth and increased pumping her fist around my cock.
I began to kiss my way down her neck and chest toward her perky little tits, my hands pressing firmly against them. My mouth seeking out her pert little nipples, hard as rocks, and I sucked one into my mouth, biting and teasing, flicking my tongue back and forth. I heard her gasp as she sucked in a lungful of air.
"Oh good God, you two!" she whispered. I pressed on Britney's head, pushing her harder into Natalie's sweet, soft pussy. She gasped more as Britney's tongue slipped inside her as far as it could go, and Britney slipped her hands up to grab Natalie's perfect little ass.
After a moment, I suddenly felt Britney turn and take my engorged cock inside her mouth. Her tongue danced wildly around my shaft and she began to play with my balls as I hungrily lavished attention on Natalie's nipples.
I desperately wanted to give my sister a taste of my cum, but I wanted to share it between both girls. I held back and slipped my hand down Natalie's body, between her thighs as I teased and flicked her clit before slipping two fingers inside her. She moaned as she slipped her arms around me, grasping at my back, digging her nails into my flesh.
I wasn't going to last much longer with all this attention. I pulled out of Britney's mouth and turned Natalie around. She immediately placed her hands on the shower wall and spread her legs as she looked back at me with an intensity in her eyes. No words were needed.
Britney grabbed my cock as I took hold of Natalie's hips, and she guided me home, stroking me as much as she could before I pressed fully into Natalie's waiting depths. I groaned.
"Oh, fuck, Natalie!" I thrust in and out of her hard, my balls slapping her clit as I pounded into her. She moaned loud as Britney got beneath us again and used her tongue on Natalie's hard clit and my cock as it plunged in and out of her tight young pussy.
She clenched her hands into fists and pressed her forehead against the shower wall, moaning and breathing hard. I could feel her walls tightening around me, and my cock beginning to throb inside her. I smacked her ass and pulled on her hair as my body stiffened and I drove my cock balls deep into her.
Natalie shuddered hard as we hit climax together. She screamed and squeezed her legs around Britney's head and I moaned loudly as a long jet of steaming hot cum shot into her, painting her inside white. I leaned forward, resting my hands on the wall, intertwining our fingers together. I buried my face in her hair and neck, breathing hard as Britney kept using her tongue, lapping up everything we had.
My cock slipped out of Natalie's pussy and Britney took it immediately into her mouth, not wasting a drop as she tasted the mixture of our juices. A few drops fell on her face as it dripped out of Natalie's pussy, and she soon began lapping up that too.
When she was finished she stood up and turned the shower off. She opened the curtain and stepped out, grabbing a towel and drying herself off. She grabbed a towel for Natalie and myself and handed them over.
"Come on, you two !! Get dried off !! It's your turn to please me !!" I looked at her and took the towel, drying myself off. I'd never experienced such a thing in my life, let alone seen her naked. Every moment my eyes lingered on her, the more beautiful she became.
Natalie and I finished drying ourselves, and I took her in my arm and pulled her against me, capturing her lips with mine. After a moment, I pulled back and looked into her eyes.
"God, you feel so amazing! I've had my eyes on you for a long time." She grinned and gave me a wink, her hands planting firmly against my chest
She leaned in and whispered in a seductive tone. "You're not so bad yourself!" She turned and stepped out of the tub, joining Britney. I stared at the two of them for a moment, drinking in their beauty, marveling at how I got so lucky for this to happen.
I stepped out and joined them. I looked at Britney with a wicked grin. "Lead the way, baby sister!" I gave her a wink, and she flashed that sweet little sexy smile of hers as she led us out into the living room. I took Natalie's hand in mine and grinned as she looked at me and we followed along.
Britney sat on the soft plush sectional sofa and leaned back, spreading her legs, beckoning us both over with the crook of a finger. "Get on your knees and lick me !!" Natalie and I complied, burying our faces between Britt's sexy thighs. Natalie went high, lavishing attention on my sister's hard clit while I licked her slit, parting her lips and dipping my tongue inside her.
Britney moaned loud with the double onslaught on her senses as Natalie and I worked her sweet pussy with our mouths. She tasted divine, my little sister did, and I desperately wanted more. Perhaps soon I could 69 with her!
Natalie was having a wonderful go at her, too. The moans she was giving against Britney's clit, and her furious actions would attest to that. I reached over and slipped two fingers inside Natalie, and she immediately pressed her pelvis against my hand. God, I loved these girls!
After several minutes I stood up and Britney shot me a look that could have killed. "What the fuck, Mike ??"
"I have an idea, Babe, don't worry." I took Natalie's hand and helped situate her above Britney, straddling her face. Britney reached up and grabbed Natalie's hips, pulling her down, burying her face in her little neighbor's sweet cunt.
She gasped a sweet, sexy sound as Britney's tongue made contact. My cock twitched. I stood and watched for a moment, drinking in the beautiful sight in front of me. The two hottest girls I've ever had the privilege of knowing, and for the moment, they were all mine.
I spread Britney's legs and stepped up to her, guiding my throbbing cock into her wet entrance, slipping inside of her with ease. Fuck, she was wet! I heard her moan as I entered her, sending vibrations through Natalie's tight pussy. Natalie shuddered with pleasure and I began pumping into my own sister, my hands gripping her hips.
Natalie looked at me with desire burning in her eyes, though for me or because of the pleasure Britney was causing her, I had no idea. And I didn't care. I leaned in and beckoned her closer.
Still riding Britney's face, she leaned in toward me and our lips met, my tongue slipping into her inviting mouth, moving in a sensual dance with hers. She grabbed my shoulders to steady herself as she rocked against Britney's mouth, moaning heavily into the kiss.
I increased my tempo and we all moaned in unison. Natalie pulled back from the kiss, arching her back as her head tipped back, her face toward the ceiling.
"God yes, Brit! Fucking lick my pussy! Oh shit!" She reached over and took my head, pulling me to her breasts. Immediately I obliged and kissed and licked and sucked, nibbling on her hardened nipples, first one and then the other.
I began to throb like crazy, my balls tightening, and Britney's pussy clenching and unclenching around my cock. "God, baby sister! I'm gonna cum so fucking hard!"
As if by magic, I shot my load, then Britney a couple seconds later, followed immediately by Natalie. I flooded my sweet sister's womb with my seed as she lathered my cock with her sweet nectar, and Natalie squirted all over Britney's face. Britney lapped up every ounce she could manage, which was a lot.
Natalie and I collapsed on and next to Britney, the three of us breathing hard, sweating. I kissed Britney and tasted what was available of Natalie's sweet juices on my sister's lips. Natalie grabbed Britney's face and turned it toward her, kissing her and tasting herself on her.
We lay there for several long minutes, basking in the afterglow as I held onto both girls, wishing I never had to let go. After awhile, Natalie was the first to stir.
"I should get back home," she said as she stood up and headed to the bathroom to grab her clothes. Without cleaning up she dressed and gave Britney a sexy kiss, then winked at us. "This was fun! Let's do it again sometime."
Britney and I smiled at her. "Yes, let's, Nat !!" she said. We watched as she turned and left.
Britney turned and looked at me, putting a soft hand to my cheek, smiling. "Well, big brother... was it everything you dreamed of ??"
I smiled back at her, turning my head slightly to kiss the palm of her hand. "And then some," I said, my eyes sparkling with lustful desire for my sweet little baby sister.
She pushed herself up off the couch and stood up. "Good !! Now that it's out of your system, that's all you get !!" She turned and winked at me, a knowing commentary that said it was indeed not out of my system, nor would it be the last. I watched her head to the bathroom. As she disappeared around the corner, I quickly got to my feet and followed her. Time to clean us both up!
