Introduction:

I was home on vacation when my younger sister introduced me to her girlfriend --- and herself.

I was home on vacation for a week, visiting part of my family, my mother and youngest sister.   I have a brother and another sister but they lived Seattle so it was just Becky, mom and me for a few days.   Mom had a date with some guy she was getting really serious about so my sister and I were alone at the house. We quickly got bored watching TV and neither of us had a date so we decided to go clubbing. She took the lead and we ended up at a favorite nightspot where we ordered beer and wings then sat back to watch the crowd and catch up.

I work in the Alaska oil fields, pretty damn far from any place that could be called metropolitan. There are a thousand times more caribou than people running around where I work and the ratio of men to women is about 100 to 1 and those women stay pretty busy after hours.  I hadn’t been laid in months and I was enjoying the view of feminine butts and tits in the dim lighting of the club.  

My own sister was looking good in a pair of painted on jeans and a cream colored peasant blouse.  She stands five-nine, weighs maybe 130. Her long legs formed into a tight round ass that rocked and rolled when she walked on 3 inch heels. A slender waist flowed up to her straight back which was covered by a mane of thick chestnut hair that cascaded in waves from her head.  The cotton blouse couldn’t hide the fact the she wasn’t wearing a bra, she didn’t need one. Her breasts formed soft smooth mounds under the material; the nipples caused noticeable tents at the peaks of her tits.   Her face is an artist’s dream, attractive but not overpowering.   An aristocratic nose and proud chin formed the boundaries for her full, blushed lips which needed no gloss to highlight them. Her eyes changed from hazel to green as the varying shades of light played with them. At 22 years old, Becky was a Playmate that Heff hadn’t discovered yet.  

As I watched the patrons dance, I noticed a lot of men staring at my sister.  She was already tall and those heels help to stand her taller than all the women and many of the guys in the club.   She drew a lot of attention and it seemed to me she accepted it as normal.   Nobody in the room knew she was my sister so I got more than one envious glance from the swinging dicks in the place.

As for me, working in the fields is very labor intensive so I am fit and trim myself.  I grew to 6’1” and move the scale needle to 210. it usually doesn’t take me long to make the acquaintance of attractive willing women. Once I get them naked, they are usually pleased with what they find behind my zipper and what I can do with it.  As Becky and I scanned the crowd I was looking for my next piece of ass. She was in the room, I could sense her, I could feel her vibes, I just hadn’t been able to tune in on her yet.

We had finished two beers and had just ordered another when Becky leaned over to me and shouted above the noise “You see her yet?”  

“See who?”

“You’re future girlfriend!   That’s why I brought you here so you could find a little female comfort tonight.”

“Christ Becky, let me worry about my love life, just because I haven’t been laid in months doesn’t’ mean I’m going criminal.”

She put her lips close enough to my ear that I could feel her breath “Tell me you wouldn’t want to fuck some of these girls. Look at that blonde, she looks pretty damn hot, I’ll bet your balls would sing praises to Eros if you could cum inside her.”

Her words shocked me a little but I had to admit the girl Becky was pointing to was one of the sexiest in the place. I put my mouth next to my sisters ear “Do you know her, can you set me up?”

Becky put her hand on my thigh and squeezed it “I’ll be right back.”

I watched my sister’s ass as she threaded her way through the dancers thinking that she was the hottest woman in the place, the blonde she had pointed out was a close second for that honor. The blonde girl saw Becky approaching and smiled hugely and threw her arms around her in greeting, it was obvious that they knew each other. The two talked for a couple of minutes then my sister pointed across the room to me. The blonde looked me straight in the eyes and smiled, nodded then said something into my sister’s ear. I stood as the two of them came back to my table.  

“Miles, this is Casey. Casey, Miles.” Casey put her hand out for me to take while looking directly at me with big blue eyes. She smiled “Hi Miles” then turned to Becky and said “this could be fun.”   She squeezed my fingers as she slid her hand slowly from mine then pulled out a chair to sit, the feel of her hand sliding from mine caused a major spill of hormones into my nuts. Becky sat with us and we ordered another round.  

For the rest of the evening I talked mostly to Casey. She was easy to talk to; we danced a couple of times and finished two more beers. Becky didn’t seem to mind that I was ignoring her, she was known in the club so spent a lot of time talking or dancing with others.  Casey and I flirted, cautiously at first but as the drinks flowed, more openly.  Becky seemed to enjoy watching the two of us hitting on each other, building up to a more intimate night. Sometime after the third round Casey whispered a couple of private comments into my ear that made me confident that this cutie and I were going to enjoy some bed bouncing after we left.  

We were all in good spirits when Becky said “Are you two ready to leave?” I was past ready, I had a semi-blue in my pants; my balls were twitching in anticipation of the blonde treat. We eased our way out of the building and caught a cab. As we settled in, Casey and I in the back, Becky gave the driver the address and got into the front seat.  

It didn’t surprise me when we pulled up in front of an apartment building that I didn’t recognize so I figured that Casey lived there. What surprised me is when Becky got out with us and took the lead into the building.  As we went toward the elevator she took my arm, Casey was on the other so I had two beautiful young women hanging on to me. What the hell, if my sister wanted to keep partying for a while longer it was ok with me, eventually I would have the luscious Casey to myself then she and I could party privately.  

Casey had a nice cozy little condo and the first place the girls herded me to was a balcony off the bedroom.  We were high enough that I could see most of the town spread out in lights below me. The view was nice but it was the view of the King sized bed that I appreciated even more,I was ready to dump my sister and get on with seducing Casey.  

In the living room Becky and I sat while Casey made drinks. I was in an overstuffed chair and Becky put her butt on the arm of it right next to me. Casey carried the three glasses to us and sat on the other arm of the chair; I was caught between two divine asses in tight jeans.  The knowledge that one of those belonged to my sister was fast becoming irrelevant, if she wanted to be around when I hit on Casey, hey, what the fuck, she might learn something.  

Becky suggested music then got up to put in a disk. When she had her back turned I put a hand on the blonde’s thigh and rubbed it appreciatively. Casey stroked my hair and bent over and gave me a light peck on the lips. She kissed me softly then breathed into my ear “You’re going to have fun tonight.” The look she gave me as she sat back up forged my steel in three heartbeats. She looked at the growing bulge in my lap and blew it a silent kiss then ran the wet pink tip of her tongue slowly across her upper lip as her eyes twinkled.

The music had a strong hard beat, the kind that caused a body to flow and pulse. Becky stepped away from the stereo and began to gyrate with the music, she kicked off her shoes and began to dance. The bass drum kept the rhythm and Becky’s hips kept time with the drum, her eyes were closed as she swayed and twirled on those long tight legs. I was fascinated, watching my sister move her body. It was electric, shocking my senses as I stared at her.  

While I was riveted on Becky, Casey was still stroking my hair, watching her friend twist and turn on the floor. I looked up at her and asked “Can you dance like that too?”

Casey smiled down on me then stood. “Hey Beck, your brother wants a show. You up to it?”

Becky opened her eyes and fixed them on mine as she replied to Casey, her voice was low, husky when she said “I don’t know if he can handle it, he hasn’t had sex for a few months, he might fuck his fist before you can get him to bed.”

“He looks like he can get it up more than once” Casey answered “let’s have a little fun.”

Casey stepped to Becky and the two of them began to dance together.  The music was subtle, sensual and the two girls matched their moves to the tune. They weren’t dancing separately as two different people, they were moving as one, bending and molding their bodies around each other, not touching anywhere but close enough that I wouldn’t have been able to put a hand between them. Every move was fluid and deliberate; I was watching an exhibition of living art. I’ve been to a few good strip clubs where the women danced together and these two in front of me were bending and twisting, giving me that kind of upscale show.  My dark haired sister and her Swedish blonde friend were turning me on; every move, every bend was done for me, directed at me, to build my interest and lust.  

About the time my cock was crying for relief from the cramped space of my pants, Becky put her hands on Casey’s blouse and began to unbutton it slowly, one button for every other beat of the bass drum. I could only gawk as the blouse pulled further open when a button was loosened.  Casey had her eyes closed as if she were oblivious as to what my sister was doing.  

The blouse fell open; Casey had beautiful tits, they were full mounds of firm creamy flesh topped by pale rose areolas; her nipples were standing as erect as my cock. I locked onto her tits as they rocked and swayed with the movement of her body. Becky glanced at me then down to my lap, by this time I had a hand full of cock and was squeezing it, enjoying the feel of the pressure. I was way past embarrassment at what I was doing nor did I care that my sister watched.  

Becky turned back to Casey and whispered something in her ear which caused her to open her eyes and look at me. When she did she put her hands on her stomach and moved them smoothly up over her breasts and pinched her nipples between two fingers.   Becky put her hands on Casey’s shoulders and turned her around so her back was to her; the music was still playing and the girls were still dancing.   My sister grabbed the collar of the blouse and pulled it down and off Casey then tossed it at me.  

Becky stepped back and let Casey dance alone, drawing my full attention. She was using tall potted bamboo plant as a pole, giving me a private pole dance. My glands were pouring gallons of hormones into my racing bloodstream; my balls were swelling with fluids by the minute. I could feel the front of my pants wet from the lubrication spurting from the head of my cock, I was ready to fuck anything right there and then.  

The object of my lust moved closer to the chair I was in and put her hands on each arm and leaned down, her face inches from mine. As her tits hung full and ripe in front of me she put one finger on my knee and dragged it up my thigh and across the inflated front of my pants.   She twisted the waist button open then felt for my zipper and gently pulled it down.   My cock sensed the freedom of the open zipper and lunged for the new space.   Casey looked at the bulging briefs then put a long acrylic nail on the nut sack hiding under my shorts and dragged it up the length of my shaft.   She smiled sweetly at the shudder she caused in my erection then stood back up and reached a hand out for my sister.  

Becky and Casey returned to the music. This time Casey was teasing my sister with her hands, touching her and caressing her body as they swayed and rocked.   Becky was turning in slow circles while Casey ran her hands over her head, neck, shoulders and back then Casey stopped my sister’s slow spin and began on the front of her.   I watched dumbfounded; cock in hand as her friend felt up my sister's tits.   She pinched the nipples though the cloth then reached down and grabbed the hem of the peasant blouse and pulled it up.   Becky stretched her arms over her head and let Casey take it off.   In seconds my sister’s blouse was flying through the air at me to join the other on the arm of the chair.  

The music had taken on a heavier beat, faster and deeper.   Casey bent over and began to whip her head in time with the music causing her long blonde hair to lash across my sister's breasts.   Becky arched backward which made her tits project further from her chest, her nipples were straining toward Casey and the long punishing hair.

I couldn’t catch my breath.   I felt dizzy and flushed; my hand was frozen on my prick.   I was watching my sister get flogged by the strands of blonde hair and the only thing I could think of was fucking her.   She wasn’t my sister any more, she was a hot fucking female and I was a hot fucking male.   My body was raging with desire for one of them, both of them; either of them.  

When Casey stood straight again Becky stepped to her and the two of them embraced, tits mashed together and began to dance again.   They were caressing each other’s back, massaging and rubbing their bare torsos.   After a minute of building my temperature to boil Casey eased back and reached for Becky’s jeans; Becky did the same to Casey.   By now I had been forgotten and the two were in the middle of a lesbian interlude.  

Fingers flew, zippers and buttons came undone and in seconds two pairs of hands were urging two pairs of pants over hips toward the floor.   My heart was stuttering in my chest as I watched the two beautiful playmates step out of their pants then clutch each other in a full body hug.   My sister was wearing a thong almost the same color of her hair and Casey had only high cut black lace panties which contrasted sensationally with the pale cream skin.  

The music kept up the beat and the girls kept up the dance.   Casey turned around with her back to Becky who coiled her arms around Casey.  They slid their bodies together for a few beats then Becky turned so the two were back to back.   On some silent cue each girl bent over at the waist, keeping their legs straight.   They were standing back to back, legs, thighs and butts pressed together while doubled over, heads, hair and breasts hanging toward the floor.  In that position they were flexing and shimmying, rubbing their asses against the other.  

By now I was openly masturbating, slow stroking my erection as I watched the incredible dance of the nymphs. Casey shot me a quick look and focused on my cock, she reached behind her and grazed Becky’s leg with her hand who turned her head to me too.   Slowly they stood then turned around again. I watched Becky put her mouth over her friends and just as the two kissed, the music reached a fast pulsing crescendo then faded to silence.   It was the perfect ending for what I had just witnessed.  

My cock was throbbing in my hand.   I wanted to pump it a few more times to finish the show but I released it and tried to sit straighter in the chair. I didn’t know what to say, I was feeling a little self-conscience about what we had all just done, what I had just seen the girls do. Those two beautiful bi-sexual bitches saw my discomfort and let me sit there for a few moments longer then Casey said to Becky “I think he liked the show but he didn’t get off.”

My sister moved to where I sat and put a hand on my shoulder, “What do you think Casey, what’s it going to take for him to get his rocks?” I was looking at my sister’s pussy outlined by the dark red thong. I could smell scented oils mixed with the musk of her sex and my cock pulsed another dose of lube from the head.   Casey reached for my hand and urged me to stand, she put her hands on each side of my face and kissed me softly then said “Take off your pants, you’re coming with me.”  She was standing close enough that her nipples pressed into my shirt, burning my skin where they touched.   I reached around her and put my hands on her firm round ass and pulled her against my body.   I felt a pair of hands on my waist band pulling it open then pushing my pants to my ankles.   Becky was helping me get undressed.   She bent over to pull them off my feet and when she stood, she ran a hand up and between my legs and put two fingers on Casey’s cunt lips.   Casey moaned softly and crushed her hips against me and Becky’s finger. When she took her hand away Becky trailed her finger tips across my balls then up the crack of my ass. At that moment it became a certainty in my mind I was going to fuck my sister, I was going to fuck her until she passed out from too many orgasms.

Casey pulled me to her king sized bed then pushed me down across it.   I was lying on my back, my hard-on straining to split open from the pent up pressure.   Casey crawled over my lap, pulled her panties to one side and centered her pussy directly over me.   Becky, who had followed us into the room put a hand under Casey and gripped my erection.   I damn near cum in her hand as she smiled down on me and stroked me three or four times. Then she held my hard-on in place while her friend lowered herself.

Casey was steaming hot and wet with her own juices.   She settled on my cock and began to roll her hips, sliding her cunt on my swollen shaft.  She put her hands on my shoulders and bent over to offer me a taste of her nipples. I sucked one into my mouth and caressed it with my tongue, Casey gasped lightly and rocked harder on me.  

Becky got on to the bed and rolled to her side to watch her brother fuck her friend.   She put a hand on my chest and started making circles around my nipple with a finger tip. I couldn’t last, 8 months of celibacy and these two women were too much for my stamina.   My balls erupted and as I convulsed boiling cum sprayed deep into the hot blonde’s body.   Casey felt me filling her womb and fell down on me and finished our torrid fling with a deep tonguing kiss.  

I was recuperating, flat on my back with my dick chilling in the air.   It was still partially pumped but resting along my thigh. Casey had left to clean up but Becky was lying beside me, still only in her thong. “Well, did she take care of your problem?”

I avoided her question with one of my own “Does it bother you that we are lying naked together on a bed?”

“It might if you weren’t so fucking good looking.  I don’t like slugs or wimps in my bed” she poked my prick with a finger “and from what I just saw, you sure aren’t sluggish or wimpy.”  

“It isn’t your bed.”

“And it won’t be; we both just had some fun with Casey but don’t get the idea that you and I are going to do something like this any bed, yours or mine.”   I saw a hint of teasing amusement pulling at the corners of her mouth as she cautioned me against incest.

I sat up “Then you better get away from me because right now I don’t see you as my sister, I see you as a damn fine piece of ass.”

As Becky and I were getting off the bed Casey came back.   She stood next to me with a rueful little grin and said “I have to get ready; my boyfriend will be here in half an hour.”

“You’re kicking us out?” I wondered aloud.

She was facing me, her hands on my chest. Casey slid one hand down over my stomach and found my cock which she gripped and stroked, “Yeah, but I’d like to see you again only next time without the deadweight hanging around.”   She was referring to Becky.  

Becky laughed lightly “You lezzie bitch, you seemed to like the deadweight tonight.”

Casey turned to my sister and kissed her lightly while pressing a hand on a breast.   “You can come back anytime too but now you guys have to leave. When Marcel gets here I’m going to rape him. It won’t be pretty.”

It was the first time in my life I’d been tossed out of a bedroom while my dick was still wet with cum.

I watched Becky get her clothes back on.   She was unbelievably sexy as she stepped into her jeans and pulled them over her butt.   The blouse went on next but the thin material didn’t hide the erect nipples or how her breasts bobbed and shook as she walked.   She had warned me off but I couldn’t get the vision of her dancing nearly nude out of my mind. I could still feel the lightness of her fingers on my cock.  

Casey kissed me goodbye and made me promise to visit her again, a promise I was sure to keep damn soon. If she wasn’t concerned that she had a boyfriend, then I sure as hell wasn’t either. We called a cab and when it came this time Becky got into the back seat with me.

Just after the taxi made the first turn from Casey’s place I felt Becky’s hand cover the front of my pants. She stretched her fingers down and stroked my balls through the material, I looked at her then spread my legs apart to give her more room to play.  Her eyes flashed sparks under a passing street light then she leaned to me and put her lips on mine,  The kiss was full, warm and promising.  Her tongue flirted with mine briefly then she pulled back.   She pressed harder on my cock and was rewarded as it began to fill her hand.   Becky laid her head on my shoulder and whispered into my ear “What I said in the bedroom was for her ears, not yours, Casey doesn’t need to know I’m banging my brother right now.”  

“Are you banging your brother?” I wanted to know.

“Not yet, but I will be in a few minutes.”   Her fingers found my zipper and pulled it down and once again my lust filled muscle was enjoying the warm night air.  My sister stroked my erection a few times then checked the back of the drivers head.   He was intent on the traffic so Becky went down on me.   I was getting head in the back of a cab by my sister and it was incredible.   She worked on me with soft lips and a flexible tongue turning me on harder than I had been with Casey. While she was fucking me with her mouth her hand was busy with my nuts.   She rolled my skin sack in her hand while giving me deep throat.   I didn’t want her to stop but we were getting close to the house, I pulled her gently off my dick. She sat up and kissed me again, with more fever and need then breathed onto my neck “I am a damn fine piece of ass.”

I tossed the driver a couple of twenties as we scrambled out of the cab, hurrying to the door, there were no lights on which meant that our mother was gone, most likely for the night.   As soon as the door clicked shut, Becky and I attacked each other.   I was pulling her clothes off while she focused on mine.   In 30 seconds we were naked, our bodies bonded by heat and arms.   I pulled her to the sofa where she stretched out, one leg over the back of it, one on the floor.   I got between her thighs and rammed my cock into her so far and hard she grunted and moved up the cushions.   Her entire body was in flames, burning me everywhere we touched and rubbed, I was being consumed by her desire, her need for me.   “Oh god yes, make love to me Miles!   I want this, I need this.   Fill me up, oh please FUCK ME!”  

She was out of control, her body thrashing and heaving under me, every time I rammed my cock into her she moaned and gripped my ass.   She put her legs around my waist, locked her ankles and humped her hips even more.   “I knew this would be good. I knew I would like you” she panted in my ear.

I lifted off her slightly and kissed her.   Becky looked into my eyes and panted “I’ve been dreaming about this ever since I grew tits.   I love you like I shouldn’t love a brother but I won't fight the feeling anymore.”   I pulled out of her slowly, reached under her ass with both hands and pulled her back onto my full, long erection.   I was riding a fast roller coaster.   Every twist, every turn she made sent thrills of excitement shooting through me.    I held on as we dipped and rolled, plunging into her when she rose to her heights, pulling out when her body dropped away in a breathless plunge.   She shuddered at the feel of my shaft vibrating against her clit.   I put my mouth next to her ear and wheezed, “I love you too Becky” then let my balls give in to the sensation of her tight cunt.  

Becky felt the first surge of cum spew into her and arched her back, pressing her pelvis hard against me. Her body was giving me permission to deposit my load of life forces.   My beautiful sister felt me cuming which set her own orgasm free.   She exploded with delicately wrenching contractions while the muscles of her pussy squeezed tight, milking every drop of sperm from my balls.  

Our mother stayed with her friend for the weekend and I stayed between my sisters legs.   After that Becky and I made some lame excuse to go visit our brother and sister in Seattle.   Needless to say we didn’t get far, we got a motel room near a beach on the ocean and got better acquainted as lovers.   She shaved my pubic hair then I returned the favor for her.   The act of screwing her naked pussy with a naked cock made our sex even better.   I brought her to climax with my mouth, she sucked my well dry.   We fucked so hard and often she was bowlegged when we left. The last night we were in the motel, she passed out into sweet oblivion after her 6th orgasm.

I went back to Alaska but only for a few weeks.   I moved back home and took a place a few miles from where we grew up, Becky moved in with me and we now live as lovers.   Mom figured out what we were doing and has accepted that her youngest daughter and second son live as incestuous roommates.

Even though Becky and I live as a couple we have no illusions of marriage, children or monogamy, she has no problem letting me date and bed Casey. Every once in a while the two women will put on another performance for me and when they do, we turn the evening into a ménage à trois, or even a quartet. It turned out Marcel is Casey's cousin and he has become a good friend of mine, it's fairly often that the four of us enjoy many long hours together.
