This is an old story of a fantasy I have kept to myself for some time and I hope it's as exciting to read as it is for me to daydream about feel free to leave your thoughts in the comments…
I'm not far from what you’d call your average guy. I'm 27 years old with a slim build that I sustain by going to the gym three times a week. I work a brutal desk job and as I get older I find it's getting harder and harder to sit all day and still look fit.
My girlfriend was the best and always took care of me. She was a plump 5'2 with delightful swollen round ass and perfect proportioned breasts to match. My favorite thing was to wrap my arms around her perfect curvy waist and squeeze her softness all over. She was a doll.
I worked my ass off, and god was I looking forward to this weekend. I was accompanying my girlfriend up to her family cabin. I’d get to spend time with her and get some much needed “R & R”. Her mother and her sister were tagging along for the trip. After all it was her mom’s cabin, and her sister was a single mom that also needed a rest from her two kids. One thing we all had in common was that we just needed to escape!
My girlfriend’s sis was further proof that the genes in this family were good! They shared the same upturned Irish nose and perfect round face. You could tell that “ass” ran strong in the bloodline. Her sister had blue eyes unlike my lady's hazel though. Her breasts were petite and as you traced down her curves the outline bowed out for her perfect wide child bearing hips. Her thighs were thick and strong and traveling down it was all supported by strong thick ankles.
These ladies weren't fat mind you. They were thick strong and solid. My girlfriend could make me hard for days, and although it was wrong I couldn't help but fixate on the thought of rattling her sister’s sturdy frame either. I was surrounded by beautiful women. This get away was going to be perfect.
The trip up was quick the lake house was only 2 hours away, and when we got up our first instinct was to unpack and wind down. It was a cool fall evening and after we unpacked we got straight to relaxing. Her mother had retired early for the night. It was just the three of us. My lady sat down next to me on the floor and her sister on the couch.
She was the dress-down attire of yoga pants and a comfy hoody. Her curvaceous thighs swelled under her own weight as she sat with her legs crossed under her. Her cute milky feet peeked out from under her exposing her thick ankles. I tried not to stare but I soaked up her image with frequent glances over.
My cock swelled with thoughts of how, much like her sister, she was firm and juicy. In one instance I thought she had spotted my gawking but I looked away. I’m sure she didn’t give it a second thought, but I had to be more careful. I had to get my mind out of the fucking gutter.
The three of us laughed and conversed in the den with some wine, and before we knew it night fell and we were quite tipsy. The more I drank the more I thought sensual thoughts. While I had full intention to fuck my woman senseless that night I still glanced over to her older sister. My mind still fantasized about those wide hips damp with desire, and as the night went on I caught her staring as well.
I was heightened and the more loose we got I became more aware of her interactions with me. She became more comfortable. We all ended up on the couch and every opportunity she got I noticed she would press firmly into me or touch my arm and back in communication. My cock ached and her small touches made my sensitive state throb as if to say "kiss me already".
We knocked off two and a half bottles and when I offered to grab another my lady groaned and protested. She had gotten way too drunk and rested her head on the couch arm. "Why don’t we take you to bed, you don’t look so good" her sister suggested in a mothering tone. Off they went to whisk her to bed.
I was really tipsy, but I wasn't ready to call it a night, and worst of all I wasn't getting lucky after all. I pushed my hips up to adjust the hard on in my pants. It pushed against the fabric and felt good as it slid into a less obvious position. 15 minutes passed and the thumping of bare footsteps came back towards the den. It was my girlfriend’s sister. "She'll be ok. She just needs to sleep it off" she said as she rolled her eyes.
She made her way to the couch and dived into the cushions ass-first. She was closely wedged between me and the couch arm, and put her hand on my shoulder again. "I'm not ready to go to bed.” I was relieved because I wasn’t either “wanna drink more?" Her breath wafted over me I breathed in deep and agreed. I was horny as hell and I just needed to get drunk, jerk it, and go to bed at this point.
"I’ll get it" she popped up excited again and ran off. In an instant she had returned with another new bottle of wine eagerly pouring. This was the glass that sent us over the edge. From there on we were slurring giggling and getting along like jolly best friends.
It got awfully touchy from there. We were on the couch together supporting each other’s drunken jello postures and as we conversed and laughed. Our glasses were in one hand while the friendly touch employed the other.
When she talked to me I focused deeply on her eyes (half of the reason was the room was starting to spin) and when her eyes met mine she stumbled on her words. She wasn't wearing a fragrance but her scent was so feminine and lulled me into a comfort zone. I kept close to stay immersed in her natural fragrance. I was still in sexual need, but this was simply bonding and I thought nothing of it until a short while later.
It wasn’t like it hadn’t crossed my mind at all. Her sister was completely “fuckable”. I was much too noble in my own head to even think I’d act on this fantastical need. However, I’d soon be put to the test, and with the ass her sister sported, my resolve might just break.
She started complaining about her home life when the alcohol really soaked in. It was hard being a 29 year old single parent. It was obvious she didn't get to talk to many people about her problems so I listened on as she let it out in a slur. I was interested but the wine made it hard to stay focused.
She was now laying with her thick legs draped over me. Her feet brushed my hand and in my boredom I half-heartedly blinked at the perverted thought of cumming all over them. My dick swelled again. Under her thick calf it grew. She stumbled over her words again but continued to speak never breaking eye contact. It was more than obvious that she noticed though. Her leg shifted as if to stroke it several times then ceased. I rested my hand on her thigh in an un-said response and rubbed up and down.
It was a bad thing to even entertain but I could see now that she too was in lust. Her story fell into the background of the sound of my boiling blood. She cleared her throat interrupting our moment and claimed the necessity for a bathroom visit. She perked up and shot off to the bathroom. Thank god.
My heart was swollen with excitement and so was my dick! I tried my best during her absence to quell any further lewdness. When she returned though so did the sexual high of her presence. She walked back to the room slowly. She was still unsteady from the wine and her scrumptious feet slapped the floor as she swung her fat luscious ass left and right. She stopped at the couch, but didn’t sit down.
She was a bold outspoken Irish girl, and what she said next shattered the sudden tension and brought back the swell. "We both need something" she said and I knew just what she meant. "I catch you looking at me strangely all the time, and now I get it. The truth is I really get it." she bit her lip. I couldn’t say this was coming from nowhere. I tried to make a last effort to save us and interject, but she spoke first "I can go into my room and masturbate like a motherfucker or …" The room was silent except for our heavy breathing. I mocked her knowingly “or…” she turned her back to me and lowered her perfect plump round ass in my lap. Her ass cheeks hugged my cock and she gently rocked back and forth cradling it and dry humping it in between her buns. She gasped "Let’s just use each other for tonight. "
I didn't protest. As she stood up her scent trailed upward. But, it was different this time. Deeper. The animal in me could smell all of her needs soaking through her tight pants. I put my hands on her ass and found the tight waste-band of her yoga pants.
I pulled down and her ass spilled out as I liberated it from the taught fabric. Her panties were the fancy kind from one of them lingerie stores at the mall. Her skin swelled out of a few tears that meant she wore them way too often. I was charmed by the milfy aura this gave her, and tore them down too, releasing the full swell of her bare ass.
She smelled raw and sexy and i kissed her ass gently as I cupped the cheek. This was happening. I turned her around to see she had no bush. The girl didn't let herself go. I stood up and lowered her onto the couch and got on my knees. Her figure was beautiful and the way her thick thighs connected to her thick ankles and then her feet drove me wild.
"I want to 'help' you first" and with that I spread her large legs and got my first look at her soft pink center. She was so pale and it was suck a marvelous mauve. I lowered my head eagerly and spread her damp lips and took the first taste of my sister-in-law. It was so wrong but it got my dick so hard.
She tasted rich with a deep aroma that rounded the saltiness of her sweet pussy. Her lips were thick and deep and a lot of my foreplay involved the manipulation of my tongue so not to suffocate in her snatch. She laid still with her eyes shut tight and her mouth held open. She rocked with waves of pleasure and squeaked at every peak of stimulation. When I found her flesh buried clit, She mouthed unheard words, and when it became too much I could hear her whisper profanity .
After spending some time passionately sucking on every little ridge of my sister-in-law it became too much for me too. My cock was now rock hard and pressed firmly against my pants. I grabbed it through my shorts and squeezed before setting it free.
She looked down at it, Beautiful sex-starved and dazed. Her lips were amazing, but I thought about what this was and refrained from kissing her. I needed her hips. They called to me. "are you ready" I asked and she nodded. Her pussy was practically a river of glistening clear and white love butter. I almost laughed at how stupid the question was. She was ready. Her pussy screamed "Ready", and now I was ready.
I wasn’t just going to cheat on my girlfriend. I was going to totally fuck her sister! It all made my head spin and turned me on at the same time. I wanted to make my sister-in-law cum. I was going to fill her snatch tonight with all I had.
She lowered her legs and I guided her on her knees and bent her over the sofa. I wanted to hit it doggy style and I wanted to hit it hard. She parted her legs slightly, and giggled in abashment. I can’t say there was much room left in me for embarrassment, especially after listening to her squeal for 20 minutes as she desperately fucked my face. I positioned myself confidently rubbing the head of my prick on her pink, and slid in.
It was nice and tight as I entered and a tight band of muscle scanned my entire length. Her meaty lips were amazing and as I made my first motion her juices coated me and collected at the openings bottom. She quietly let out a deep moan causing me to throb inside her with excitement. As if her voice commanded me to cum. I motioned in and out again making sure the machine that was our parts were oiled well.
Her pussy was good. So fucking good, And as I started a rhythm I got to know her parts well. I motioned in and out feeling for the sweet spots that would send her over the edge. I wanted to hear her deep vulgar moan cry out for my filthy cock again. I pressed into her and I could feel the slick inside of what would be the top of her love cavern. I pushed in feeling the resistance of that wall as I fucked her like an animal. I pushed in again and again wearing her inner surfaces out, and observing her reactions. She was now panting and grabbing on to the sofa pillows for dear life. Every time I fucked her she let out a deep guttural "oh".
She would swing her head back with pleasure-filled and half shut eyes and I could see her face shimmer with sweat. Her upper lip a collection of dewdrops and her forehead wet as if she'd had a hard day’s work. As our eyes met we couldn’t help but exchange a warm smile.
I took the opportunity to watch her eyes grow wide as my rhythm exploded and I worked her pussy harder. She shoved her face into the pillows as her cries became wild and spontaneous. By now I could hear the sloppiness or sex juice and sweat between our legs. This was complimented by the uncontrollable deep crying into the pillows. I could hear it, I could smell it, and when I looked down oh I could see it.
She now had a wonderful reserve of creamy frothy pussy juice collecting. She looked back again and caught my admiration of it and said stuttering and out of breath "I get reeeeally wet" before turning back around to continue receiving my bone.
I fucked her hard and steadily inching her towards climax. I needed to make her cum. My dick massaged the swollen muscles of her insides and as she got there she seemed to cry in relief as if I was giving her breath. I knew something big was coming. Her legs trembled sending waves up her big ass and she dug her nails into the sofa fabric for dear life. She lowered her head and exhaled sweet nothings interrupted by the frantic whispers of "fuckfuckfuck" or "yesyesyes".
I fucked my perfect sister-in-law until the rhythm was disturbed by the abrupt jerking of her hips. Good god she was cumming! It was a calm, subtle, chaos and I kept fucking as she jerked and convulsed. She made animal noises as my cock stuffed her contracting pussy now I too was now at my edge. I heard again the now musical whispers "fuckfuckfuck" and then a groan. I was surprised by a gentle warmth coating my balls. Her overworked pussy overflowed with a small finale' of love juice and it ran down both our legs. I was now covered in this girl’s pussy and I couldn’t hold out another minute.
She was so sweaty and beaten by my cock she looked like a filthy little angel. I could tell she was exhausted but she pushed her over stimulated body gently into mine. She looked back again breathing short breaths disturbed by the shockwaves of pleasure and nodded in encouragement. I stuttered "Where do you want it?" but before I could even finish she interjected “in! in! IN!”
I couldn’t give it a second thought. She steadied her now shaking frame and arced her back positioning her pussy to take everything I had. So I gave it to her good. Pump after pump of my cum deep inside her deep pink abyss and as I came I grabbed her shoulder and her chunky rib. I wanted it in her as deep as possible. I was blinded by the need to become a part of her. I held us there still as my dick emptied its final blast.
We must have stood there wedged together for about five minutes trembling in pleasure and dripping our passions onto the wood floor of the cabin. When we both stood up it wasn’t awkward at all, like I thought it would be. We smiled at each other ear to ear. "did we put each other to good use?" she nodded in a fucked haze with stray sex hair about and raised her pants to contain the wonderful batter I mixed in her pussy.
That night we cleaned up and sat back down on the couch for some TV and more chats. For each of us the sex was fucking perfect and in a way we fell in love with the bond we made. We both loved her sister very much, and because of that it made it easier to cope with the sinful nature of that night. We had a night that was never repeated but always remembered.
