Incest MFF threesome

Long time lurker, first time poster. I’ve never done this before so here is my first attempt. There may be a few typos, sorry wrote this all on my phone.

It was a beautiful 70° day in the mountains. The sky was crystal clear with a slight breeze, clean fresh air. “Hurry up John!” My sister yelled, echoing through the trees. We were on vacation at our family’s time share in Colorado.

“John, where the fuck are you!?” My sister yelled again louder as she got closer. Maggie, my girlfriend, and I snuck away for a minute for a quick make out session. My girlfriend was tounge deep in mouth when my sister stumbled on us. She laughed as I embarrassingly broke lips with my girlfriend. “What do you want Lindsey?” I asked her…”Mom and dad are going on a historical tour and they want us to go” I rolled my eyes “yeah yeah I know, I don’t want to go either. But the quicker we get this over with the quicker we can get back and you two glcan get back to making out” Maggie giggled a little and blushed…”Come on baby, it may be fun” as she playfully bit her lip. “Listen to your girlfriend, shit you may even learn something!” Lindsey mocked.

We made our way back to the cabin, as we approached mom and dad had finished unloading the Tahoe. “C’mon guys, we’re going to be late! Dad yelled” we picked up the pace and hoped in the car. I opened the door for Maggie and she quickly got in, shoving her ass in my face. Not going to lie it was nice as she was wearing short shorts. Maggie made her way tonthe back seat of the Tahoe and sat down as I made my way back there she blew me a kiss. I sat down as mom and Lindsey closed their doors after getting in, and off we went.

It was a quiet ride up to the historical site, beautiful tall evergreen trees with bright sun beams piercing through. While I was admiring more of the scenery Maggie gently took my hand and began slowly sucking on my finger. This of which got my immediate attention. She put her finger up to her mouth and gave the universal “shh” sign. Maggie continued sucking on a finger softly getting it all wet with her spit. My heart rate was elevated and felt nervous. She then takes my hand and puts it down her shorts and gently guides my finger over her womanhood.

My penis immediately springs up with a slight throbbing sensation. She stared at me as she ran my finger back and forth over her clit, while looking at me with a mischievous smile. After a minute of teasing me she removed my hand and cleaned up my finger, enjoying her own flavor. We met through a friend of ours at a graduation party they had, while their folks were in the Bahamas. We hit it off and turned out we had many similar interests …… she was the book smart type who always had good grades. I honestly didn’t think she liked me when we had classes together. I didn’t have many friends in school and fell into the outcast group but that didn’t bother me, my parents moved around a lot and never bothered trying to make many friends.

We arrived at the historical park and grabbed our tickets. Unfortunately we were late and had to wait for the next guided tour to start. Maggie and I walked around the indoor museum they had, looking at the artifacts. The museum only had a few people…a few couples and families. There was a moment when no one was around, so we took advantage of it and started making out. Maggie was walking me backwards, guiding me to the glass wall. I stopped and she kissed me a bit more and slowly pulled away. I felt her unzipping my pants. “What are you doing!?” I asked nervously “Relax baby, I want you to enjoy this” she said as she reached into my fly and grabbed my semi hard manhood. Maggie shoved her tounge back into my mouth as she pressed herslef up against me, forcing me back against the glass. As our tounges were flicking each other she gently grabs the base of my shaft and begins pumping her hand up and down on my penis. I’m fully erect almost immediately. I’m throbbing at this point.

I’m still worried we may be caught and as I open my eyes to look around, Maggie kneels down and licks the underside of my head. HOLY SHIT….I said to myslef. “Thats feels so good, I whispered to her. She smiled and then pursed her lips, all while slowly forcing the tip of my penis into her mouth. Maggie’s mouth was soooo warm it felt almost hot, it was an amazing feeling. She looked up at me as continued, stuffing the rest of my shaft in her warm and wet mouth. “Oh my -“…..I couldn’t even finish my sentence as she began taking my penis in and out of her mouth. It felt soooo good, I found my hands on the back of her head. Maggie unsheathed my rod from her mouth as a little bit of dribble landed on her shirt. “May I please take all of you? In the back of my throat?” She begged. “Yes” I said shakingly not knowing what that meant……

My girlfriend re-inserted my spit covered shaft into her mouth…slowly….very slowly…..enjoying each muscle….every ridge…and every vein that she encountered. This time it was tingling….sensational. She kept going slowly taking every inch, not even breaking eye contact she passed halfway…then three quarters as she swallowed gently forcing more of me….it began to get a little firmer but still soft and just like that I could feel my head all the way back in her throat. This was the single most amazing thing I’ve ever felt! I was speechless, breathing heavily enjoying the moist warm cavern of Maggie’s mouth.

Suddenly we heard voices, and she qietly removed my shaft from the back of her throat and wiped the mess from her lips. All the while I tried stuffing myself back into my jeans witch was very difficult to do with a massive erection. The voices got closer and I soon realized it was my parents. I don’t think they saw anything…whew that was close. “You two ready?” My mother asked with my father and sister in tow. “Yes ma’am” Maggie said gleefully…..as she wrapped mer arm around my bicep. “Let’s go sweetheart” she said.

The tour was pretty fun, it was very quickly becoming the best trip ever…ever….of all time. We made our way back outside and linked up with other people who were in the same tour group. Maggie was getting some looks from aome of the other guys and men in the group….I even caught Lindesy checking her out. I mean she was hot as fuck and looked WAAAY out of my league. My sister was always kind enough to point that out. The skin tight workout shorts she was wearing didn’t help….they captured the perfect curvature of her figure and toned abdomen. Her physique was borderline textbook. Her loose tee-shirt was covering her exceptionally perky breasts, they were so nice….even more so now that she had her nipples pierced. I Remember when she showed them too me. Maggie really came out of her shell since we graduated. Fuck I wasn’t complaining.

The tour went on for about an hour and a half and was pretty interesting, I always enjoyed history and and anything to do with the outdoors, paired with this beautiful goddess who chose me….and it was one of the best days of my life. Maggie flashed me, jiggling her perky pointed breasts at me as we were finishing the tour. We all packed back up in the Tahoe and headed back to the cabin.

When we arrived back at the cabin, it was about an hour and half until dinner. “I’m going to go shower” Maggie said. “Me too chimed in Lindsey”. They made their way back to their rooms and my dad came over from the kitchen. “You guys will be on your own for dinner tonight. Your mother and I have dinner reservations, and afterwards are meeting up with the Cunninghams afterwords for drinks and dancing” the Cunninghams have been family friends since before I was born. “No worries dad, we will be just fine”. “Great! Your mother and I will be leaving in an hour. If you need anything, text us!”….Yes sir” I replied.

I made my way back to my room, it was the farthest part of the house, which was fine by me…less foot traffic and quiet. I passed by Maggie’s room and she was still in the shower. So I texted her that I was going to lay down for a nap and that my parent’s will be leaving for the evening. I passed by my sister’s room and her door was partly closed. I knocked and she came to open it, dressed in a bath towel. I stared at her for a moment, after I looked down at her feet and super short towel of choice. Her legs were still kinda gleaming from the lotion she was still rubbing on them. “What!?” She asked as I snapped out of it…”Mom and dad are going out for a few hours for dinner and they are meeting up with the Cunninghams afterwards” I replied. “So we are on our own for dinner”. “That’s fine Lindesy replied, I bought some groceries earlier so I got steaks and what-not”. “Okay cool, you want me to cook them on the grill then?” I asked…”works for me” she said just as her lotion bottle slipped out of her hands. She reached forward quickly trying to grab it…her towl popped off…and now my sister was completely naked standing there in front of me. Her large breasts just staring at me, toned stomach and hairless body. I was grossed out at the sight of my sister naked….or was I? My hormonal ass didn’t know what the fuck was going on…do I look? Do look away? “WELL????” Lindsey asked impatiently. I Noticed she hadn’t bothered to cover herself up. “Are you going to pick it up for me!?”…”oh s-sorry” I quickly bent over and picked it up, handing it to my sister. “Thanks little brother” Lindsey replied as she slowly closed the door.

I stood there for a moment, baffled by what the fuck I just witnessed….I knew I was supposed to be grossed out at my the sight of my naked sister…..but….I wasn’t…..NO! THAT’S WRONG I said to myself. Yuck gross! I said to no-one. I tried to clear my mind….happy thoughts…and immediately the thoughts about what Maggie did to me earlier in the museum, came back to me and immediately forgot about my sister.

I made my way to my room. I closed the door behind me, changed into my athletic shorts and hoped on my bed. The deep throating my girlfriend gave me earlier popped into my mind as I started drifting off. I couldn’t get it out of my head. The dream was so detailed….I started to feel my shorts lift up as I was getting an erection. As I left consciousness my dream of Maggie resumed, fuck it felt soooo good….really good….too good….real….I opened my eye a crack to see a head bobbing up and down, hearing a slight slurping sound….HOLY SHIT IT WAS MY SISTER. I froze….I didn’t know what to do. I just laid there and hoped she would just leave. I pretended to roll over in an attempt to get her to stop, but she gently placed her hand on my pelvis to keep me on my back. Lindsey began to speed up…..sucking harder…..my heart started speeding up a bit, I couldn’t last much longer. I hate to say it…but it felt fucking amazing, I thinking I was beginning to enjoy this. A few more pumps and Lindsey made one more thrust with her mouth and forced my entire penis into her mouth and deep into the back of her throat, holding it there for what seemed like forever…..until finally she released me from her warm salivating mouth. I think she finally gave up. I just barely opened my eyes to see Lindesy wipe the spit from her lips and leave my room quietly.

What. The. Fuck. Just. Happened!?

I waited a few minutes for my erection to go away and got up to close my bedroom door. It was almost time to start dinner, so I jumped into the shower and put on some fresh clothes. I headed back to the kitchen and found Maggie there washing the salad and vegetables. She was looking beautiful, hair all up in a bun wearing a strapless sundress. “Hey baby” she smiled “How was your nap?” I took a second to think about my response….do I tell her? What would she think? She would be grossed out. “It was fine. Had a crazy dream about what you did in the museum” She blushed and blew me a kiss. I go to the fridge and grab a soda out. Lindsey walked in as I turned back around. I almost froze. Staring at her in a tube top and pleated skirt “How’d you sleep?” my sister asked…still kinda frozen I fumbled for words. “Good, good, It was good” I replied nervously. It appeared she had a smirk on her face for a second…..what was that about? I wondered….

I grabbed the steaks off the counter, and practically ran outside as quick as I could without seeming suspicious. With the grill now fired up I began cooking the steaks. I sat down on the outdoor furniture and inhaled the fresh mountain air. Before long, Lindsey came out and brought me an empty place with tongs to flip the steaks. “You left these inside” she said placing them on next to the grill. I looked at her back, wondering if she was messing with me. Lindsey ends up dropping the tongs on the deck. She quickly bends over, revealing the fact that she has on NO underwear. Her butt was perfectly round and looked super soft. She was bald, save for a small little tuft of pubic hair just above the top of her slit. It caught me off guard and I ending up getting caught staring. She stood up and looked over her shoulder at me “Oops, sorry about that” I was starting to get hard!!! Wtf!? Seriously!? I was embarrassed and didn’t reply. My sister went back into the kitchen and washed the tongs. I got up to check on the steaks and as I turned around to ask Lindesy if she had the tongs, there she is standing there flashing me. Her big, soft, supple tits were in full view. My god they looked amazing! As I looked at them I noticed her nipples were pierced. That seemed to excite me some more. I was desperately trying to keep my erection at bay….and was losing. My penis started becoming more and more erect. “Lindesy you need to stop! This inappropriate and wrong!” I exclaimed “oh come on” she replied in a pouty tone “don’t you want to know what I taste like” as she lift up the front of her skirt, flashing me with her genitals”

I swallowed hard, my stomach was in knots. My penis seemed to know what it wanted though. Melissa walked towards me, her breasts just hanging out, jiggling slighty as she closed the distance. “C’mon…feel them….you’ll like them…. I promise!” She grinned. My sister was within inches of me, looking up into my eyes. Slowly I reached up, and I ever so gently ran my fingers under her tits, feeling the warmth increasing I groped them. Wow they were soft, and felt amazing. “Whatcha guys doing?” Maggie asked out of no where. Oh shit, this isn’t going to end well. Lindsey brought her tube top up slowly, covering her chest back up. “Nothing. Just comparing our height” Lindsey replied. Lindsey was a whopping four feet nine inches tall. I easily had a foot or more on her. “Are the steaks done? I’m starving” maggie said almost whining….”yeah sweetie, was just pulling them off” I grabbed the tongs from my sister, grabbed all the steaks and headed inside.

The girls had set the table and poured some wine. Our folks weren’t home so who cared. I put the steaks on the table and the girls quickly picked the ones they wanted, and immediately started digging in. After a delicious dinner and a full bottle of wine we headed downstairs to the game room and decided to watch a movie. Nightmare On Elm Street! My pick. We were definitely watching that classic slasher flick. As I sat down on the couch, Maggie turned the lights down low, then quickly ran over and plopped down right next to me. Lindesy sat down next to me on the other side. Both of them were right practically sitting on top of me. I could feel the warmth from each of their bodies. I started the movie and leaned back finding a comfortable position.

I put my arms around Maggie and before long Mlher hand was on my chest, which she gently ran up and down under my shirt. It felt great. I exhaled and let out a deep sigh as her hands kept wandering. Maggie slowly ran her hand down under my shorts and softly teased my base of penis. Enjoying her wandering I didn’t stop her…despite my sister resting her head on my right shoulder. Maggie began groping my shaft and tugging on it, causing it to get harder. By now my sister had to see that I was full mast. I didn’t care anymore. Maggie and I started making out, quietly at first but eventually started groaning a bit louder as she began stroking my fully erect shaft. I looked over casually to see what my sister was doing and she had one hand up her skirt, the other on her boob. She was moving her hand in a small circular motion….was she masturbating? I didn’t care as at this point Maggie had stood up and removed her sundress in front of me. She was standing there in just her thong, as her very perky pear shaped tits were just out in all their glory. My sister definitely noticed and reached up cupping Maggies left breast. “Oh wow” Lindsey whispered…”Are those real? They’re so firm and perky” Maggie looked at her with a sinful smile “Oh yes, grew them myself” she said as she nelt down and removed my shorts. My penis was out in the open, again full mast and rock hard. Maggie began licking the head and quickly inserted it into her mouth. ” wow little brother, she’s a keeper!” Lindsey said. “Oh yes!” I moaned as Maggie took me all the way into the back of her throat.

Lindsey slowly got up off the couch and removed her tube top, her perfectly round full breasts let loose. She slipped off her skirt and sat back down on the section part of the couch just beyond where Maggie was kneeling down, and positioned herself so I could see her. Lindsey sat on the very edge and leaned back, opening her legs to me, I could see her labia and lips opening like a flower. It was fucking hard. I don’t know how, but my shaft had become harder and started throbbing. Maggie picked up her pace…..Lindesy started rubbing her lips teasing me, she licked her fingers and started playing with herself as she watched Maggie sucking me off. “Does this turn you on little brother?” asked Lindsey….I nodded yes in response. I was in ecstasy as I was getting my dick sucked. Maggie finally came up for air, spit and precum was dripping from her mouth to my penis. Lindesy stopped rubbing her clit, came over and licked the spittle off my girlfriend’s mouth. Damn this was so fucking hot. I didn’t care anymore. Thisnwas going to happen.

After cleaning up my girlfriend, Lindesy take her place, getting down on her knees and puts my manhood in her mouth. Holy fuck was it warm…it was practically hot. Fuck it felt so good. “See, I told you he would like it” Maggie said playfully to my sisters. “Mmmmm uh huh” Lindsey muffled with her mouth stuffed full of my manhood. Lindesy starting picking up the pace, sucking harder on my penis. I was close to cumming. I put my hands on my sister’s head guiding her almost. I could feel a release was imminent. Lindesy kept up her pace, fondling my balls gently. “Oh fuck, I’m going to cum” I whispered to her. “Where do you want to cum baby?” My girlfriend asked “on her nice tits? On her beautiful face? Or do you want to unload in the back of her throat?” Maggie asked. Lindsey quickly removed my girth from her mouth and quickly said “Mouth!” and immediately shoved me back, deep into her throat “well, you heard her baby” Maggie said and withing seconds “fuuuuuuck I’m cumming” and balsted my hot, thick cum deep into the back of my sister’s throat. Lindesy gulped down every spurt of cum that she could. My sister drained me dry. Maggie began making out with me as Lindesy cleaned my shaft of every bit of cum she could find.

“Did you enjoy yourself little brother?” Lindsey asking in a coy manner. “Oh yeah!” I replied. “Good!” Maggie said as she stood up. Maggie leaned over and started making out with my sister. I don’t know why, but that was fucking hot. Lindesy still on her knees broke free of my girlfriend’s mouth and turned her around. With her head at perfect height to Maggie’s ass, she spread her legs slightly and started licking her slit from behind. Maggie looked like she was already super wet, and made her way up to her asshole. Lindesy made sure to get it just as wet. A few mintues later my sister stood up and turned Maggie’s back to me and made her sit down towards my shaft. Lindesy grabbed my rod and guided into Maggie’s asshole. Holy fuck did my girlfriend have a tight ass. I moaned as Maggie slid down my rock hard cock with her asshole. She whimpered a bittle in ecstasy as she could feel every vein and muscle on my thick penis in her super tight anal cavity. She was moaning so loud that Lindsey started making out with her. My sister then started rubbing Maggie’s clit, hoping to stimulate her some more. It was helping as now she was completely sitting on my cock, all the way down to the base of my shaft. All nine inches of me was inside Maggie’s ass. Maggie could barely move as she was experiencing things she never had before. She was practically trembling. My sister kept aking out with her and rubbing her clit. I could feel her asshole tightening on me, and holy shit did that feel amazing. My sister kept rubbing Maggie’s clit and before long she had her and the verge of a monstrous orgasm. Maggie dug her fingernails into my legs as she was nearing a feeling she’d never quite experienced before. Maggie started whimpering “FUCK FUCK FUCK FUCK FUCK” she yelled. Maggie was convulsing from the orgasm and squirted a stream of ejaculate that shot out about five feet. She screamed in pure ecstasy. Seconds later she fell back on me…. my sister knelt down between her legs and licked up the mess she made on herself. “Wow you taste amazing” Lindsey commented, as she stood up and kissed my girlfriend on her on the lips. Maggie was breathing heavily as she rolled to the side of me, gently pulling herself from my rod that was embedded in her ass.

Once I was free and clear, Lindsey stepped up on the couch. She was now standing over top of me. She knelt down and proudly presented her slit inches from my mouth. I could feel the warmth radiating from her genitals, as she gently lowered herself onto my mouth. I never thought in a million years that my sister would be grinding her pussy on my mouth. Holy shit did Lindsey tatse good! My cock twinged as I enjoyed sucking on her labia. I began to thrust my tounge in and out of her hole, causing her to moan. It was literally like I was eating summer fresh honeydew melon. I casually ran my tounge down to her asshole, causing her to take deep breaths. Lindsey then forced her clit into my mouth, and I tenderly began sucking on it. All the while I slid my middle finger knuckle deep into her tender slit. I quickly began stimulating her gspot…..she was as good as done. After a few minutes of fingering and Lindsey’s thighs started shaking and tensing up around my face as she came to climax. My sister couldn’t hold it back any more and creamed all over my mouth. I lapped up her creamy nectar. She slid back down towards my waist licking herself off my face and mouth.

At this point I was so fucking horny. I needed to fuck something. Maggie, the good girl she is, was on her back with her leg spread open…..she gave me the look that she wanted to be bred. I towered over her, my rock hard cock mere inches away from her soft tender womanhood. “Wet it please” I asked her. Maggie opened her mouth and I stuffed my meat into her mouth for a good minute or two while she slobbered all over me. “Perfect” I said as I removed myself from her mouth. “Please stick in my pussy baby” pleaded Maggie “please I want to feel you-” and before she could finish her sentence I slid my entire nine inch rod deep into her all at once. Maggie let out a deep gasp. “Fuck it’s so tight” I moaned. Maggie was beyond tight. I reached down and begun rubbing her clit, in an attempt to make it a wee bit more pleasurable. “fuck me, baby…fuck me hard…pound my pussy” so I obliged. I removed my entire rod from her and immediately slammed it back in….Maggie screamed. I pulled out and thrust into her again, she screamed again. At this point my sister recovered a bit and came over to watch me fuck Maggie. l removed myself yet again from Maggie’s super tight slit. Lindsey spit on Maggie’s pussy getting it lubed up again, and guided my thick cock back into her. Lindesy started kissing and licking Maggie’s clit as I sped up my thrusting. “That’s it little brother, fuck your girlfriend. Yes….just like that” as she watched me drilling her. Between her moaning and ecstatic sreaming, Maggie would belt out “harder”. I sped up my thrusting, my sister now rubbing Maggie’s perky tits, twisting them occasionally. Her eyes bagan to roll back as I slammed my rod into her slit unrelentlessly…. harder and faster. Maggie couldn’t control herself any more and climaxed, tightening so hard around my shaft, I thought I was going to get stuck. Well that was enough for me and a few minutes later I came. In the final deep plunge I erupted… hot cum deep poured into her vaginal cavity….I kept pumping and puming more cum into her. After a few more pumps I pulled out of Maggie and some of my cum dribbled out her pussy….Lindsey helped herself to the creampie that unfolded before her. After my sister finsished with that she then proceeded to suck Maggie’s juices and my cum off my shaft.

“Mmmmm…my turn” Lindsey said grinning at me. Next thing I knew, my sister was standing over top of me on the couch. “You ready little brother?” And in one quick motion she squated down, guiding my thick rod into her womanhood. She tenderly rubbed the tip of my penis up and down over her clit. She gasped as I made contact with her sweet spot. I reached and gently caresed her big soft tits….Lindsey giggled as I pinched her nippes. My sister’s breasts felt amazing, I couldn’t believe how good this felt. Maggie got up and walked over to my sister and started making out with her. Maggie gently encouraged my sister to squat further down on my rock hard penis. “This is what a pussy should feel like little brother” Lindesy said breaking away from kissing my girlfriend. Fuck it felt amazing, it was unbelievably warm….incredibly soft inviting ….almost hungry. Maggie got behind my sister and she started playing with her tits. My sister slowly began to start grinding forward and back wards on my shaft. With each passing thrust Lindsey’s breathing and moaning got louder. I could feel my sister’s juices coating my rod, squeezing me…..”Oh little brother, your cock feels so good. Do you like fucking your sister?” Lindsey said as she looked down at me, her eyes full of excitement and lust. I nodded “yes, It feels amazing” as she continued to grind on me. In between Maggie groping my sister, I would lean forward and gently suck on my sister’s nipples, tenderly nibbling on them. That got her really excited and she continued to ride me harder and faster. “Lindsey I’m going to cum soon” I moaned while she leaned forward, bracing herself on my pecs. “Oh go a head sweetie, you can cum inside me. My pussy is just for you little brother.”

I sat forward, holding on to my sister…my cock deeply planted inside her. While standing up, Lindsey wrapped her legs around me, refusing to let go….I turn her around, and lay her on her back on the sofa. With one swift motion, I pull my sister’s legs apart and spread them wide, pushing them back towards her head. She looks up at me with a begging look on her face. I begin pounding her, violently thrusting my bulging rod deep into her slit. Lindsey clawed at my chest and back as she was feeling the sensation of being pounded by her brother. Maggie took the opportunity to straddle her face, teasing her with her sweet pussy. Lindsey immediately grabbed her ass and began tounging my girlfriend’s pussy. Maggie was definitely enjoying herself. “Cum in me little brother, CUM IN ME! MY PUSSY IS ALL YOURS!!!! I want your cum!” Lindsey begged as I sped up faster. With a few more pumps, I gave my sister what she was asking for. “Oh god sis, I’m cumming…..fuck your pussy is tight” I said while my warm sweet cum erupts into my sister’s pussy. I couldn’t stop cumming, she was so tight and her moaning just made it more pleasurable. “It feels so good little brother, don’t stop” ……”mmmm I can feel you throbbing inside me” my sister said while smiling at me.

Maggie got up from grinding herself on my sister’s face and proceeded to suck some of my cum out of her. After a few seconds, my sister pulls Maggie up to her and begins to lick some of my cum off her lips. They both giggled and smiled as they kissed each other. “She’s a keeper little brother” said Lindsey as she winked at me. “And don’t forget little brother, this is yours…anytime anywhere” Lindsey said as she pointed to her groin. “Wow, that’s a helluva sister, she must really care about you”.

Part 2 is being worked on
