I had always been sexually attracted to my sister for as long as I could remember. How could I not be? She is a petite woman, about 5'3", 110 lb., dark brown hair a bit past her shoulders, hazel eyes, rather thin but extremely sexy lips, and a tight little body that stays firm from regular workouts. Her breasts are small but perfectly round and firm, and her ass is gaspingly tight. There is no question she is gorgeous, and I've been listening to my friends talk about wanting to bang my sister for many years now. What they don't know, and what no one knows, is that I've always wanted to also. Yes indeed, my older sister Jill has been the subject of my sexual fantasies ever since I first learned about the wonderful world of masturbation.
Jill is my only sister and about 4 years older than me. Being the only siblings and living in an area with no other kids around, her and I were always very close. We've always gotten along well and been the best of friends. At one point, her and I were going to school and working at the same places, and so we'd end up being with one another pretty much every minute from morning to night. Growing up in a small house, we even shared a bedroom with bunkbeds, and nightly I'd lie in the bunk below her dreaming about how badly I'd love to be sharing bunks with her instead.
I had always felt some guilt regarding these feelings I had for Jill. As a young teenager I felt like it was wrong for me to peek at my own sister sunbathing in the backyard while I stroked myself with fury. It had always thought it an underlying immoral thing, when I'd itch so badly to catch a moment of her naked and wet body when she got out of the shower. Originally I had thought it was a pubescent phase that I'd soon grow out of, but this desire for my sister continued and grew stronger as both her and I reached our mature, adult lives. Every day I'd put my guilt on hold for the few minutes it'd take me to think of Jill and explode with incestual orgasm. I would constantly set small mental goals for myself in hopes of ridding my mind of these 'wrong' incestual thoughts, but such were never met. I'd promise myself to stop thinking of her once she got married, or once she had a kid. But here I am now at 28 years old and my sister at 32, and I still yearn for her as bad as when I was 13.
So I learned to accept it, and even sometimes try on occasion to include it somehow in my more physical sex life. I would call phone-sex operators and get off on the thrill of finally telling someone about my feelings for my sister. Even the act of hearing myself say it out loud to someone that I wanted to fuck my sister, would supply me with a body trembling thrill. At one time, I even dispelled this fantasy of mine to an extremely open minded girlfriend, who would ask me questions about my sister as we fucked. I'd search out erotic stories and pictures on the Internet that somehow reminded me of myself and Jill. And many many times, I'd contemplate just telling Jill one day how I felt, with the small hope of her also wanting me. I dared not though out of the fear of how it might potential ruin our brother/sister relationship forever.
About 6 years ago I moved to another state, but only a 4 hour drive from Jill and her husband's place. With it being such a short drive, I'd visit her often, even if just for a weekend or a few days. I loved these trips more than I can convey, since usually I stayed in a guest room located directly next to my sister and her husband's bedroom. I'd masturbate vigorously hoping even to just hear some sounds of sex, as my sister was made love to by her husband. Such things never happened though, and at best I might catch a brief glimpse or two of her toweled body coming from the shower.
About a month ago I decided to pay my sister a visit, since I had a few days off from work. I figured I would come there on Thursday and make a long weekend out of enjoying the hot summer sun with her and her family. When discussing my plans with Jill, she told me that both her and her husband would be working the day I planned on arriving, but that it was OK for me to let myself into her house using the hidden spare key. I suggested that I come later on in the day, but she insisted that it'd be better if I traveled in the daylight and without having to deal with the rush hour traffic. I agreed and thanked her for being cool and letting me hang out at her place alone.
On the drive there, I began to think about the potential I might have to see Jill in some sort of sexual way or state of nakedness. Knowing that I'd be alone in her house for many hours, I dared to think that I might scavenge her underwear drawer or masturbate onto her pillow where she laid head at night. All the while, fighting these urges and telling myself how wrong it is for a man to think of his own sister in those kinds of ways.
After a few hours of driving, resisting my incestual thoughts, and attempting to ignore my raging erection, I reached my sister's house and pulled into the driveway. I found the hidden spare key where Jill had told me it was, and let myself in. Eager to masturbate, I set my bags down and plopped myself onto her living room couch.
Immediately I was feeling the rush of the situation. Although I knew that my sister and her husband wouldn't return home from work for many hours, there was still a thought in the back of my mind that knew there was at least some potential of getting caught. After all, I was masturbating right there out in the open, in my sister's house, and on my sister's couch. The blood filled my sex in full force, as I yearned for my sister to walk in and catch me with my cock in hand. I wondered what I'd say. I wondered what kind of look she'd have on her face when she caught her little brother, fully erect and stroking himself. If it happened, I wondered if I'd tell Jill that I was thinking of her while doing it.
As my momentum started to build, I thought I had heard a soft pant. Quickly I stopped stroking to see if I had really heard it or if my fantasies had just gotten the best of me. For a few seconds there was silence, and just when I had dismissed the sound as coming from inside my head, I heard it again. Immediately I zipped myself up, and investigated further.
My heart was racing at the thought that I hadn't been alone. My cock was throbbing thinking that it might actually have been my sister there, maybe even watching me. Here I was completely absorbed in the fantasy of getting caught, and now it seemed as if it might have been a reality. My heart skipped a beat hoping that it was.
I began to tiptoe my way around a bit, hoping to decipher exactly where the sounds were coming from. As I did, I heard another which was different than a breathe. It was more of a 'wet' breathe, if such an adjective will suffice, and it seemed to be coming from the end of the hall where both the guest-room and my sister's bedroom were located. I slowly and quietly made my way down toward the bedrooms, and heard the sound louder as I approached. Indeed it was a combination of breathing and slurping, and was definitely coming from my sister's bedroom.
I was ecstatic. The thrill of potentially being caught was nothing compared to what my imagination was dreaming up now. I positioned myself closer to the bedroom door, hoping that the sounds would weave me an amazingly detailed mental picture. My mind filled with thousands of thoughts a second of just exactly what might be happening behind that door. Had my sister forgotten I was going to visit her that day? Did her and her hubby stay home for some hot daytime sex while the kids were at summer school? Was Jill giving her husband a blowjob, or was she getting her pussy eaten? Would I be daring enough to stand there and masturbate to the sexual sounds of my sister fucking her husband?
Just then a moan filled my ear-space. There was no questioning it now, there was something definitely happening behind that door. Something involving breaths, slurps, and moans. The image filled my head of my sister mounted atop her husband, bucking and grinding away at his cock, as she made love. I was overwhelmed and unable at that point to even care about ramifications. I took out my penis, and began stroking it hard and hasty, while my ears and mind were filled with what I had always hoped for when making these visits.
Just then it hit me. How could I have been so stupid? Panting. Slurping. Groans. I mean c'mon, would my sister actually forget that her brother was coming to visit her, take off work, have her husband take off work, and then fuck him with reckless abandon? Hell no. My own fantasies had completely distorted my perception of reality, and right then I knew it. These sounds were not the wondrous vibrations of sex being made, but rather my sister's dog.
I had completely forgotten about the dog. I smirked to myself as I remembered how my sister's dog very often spends the daytime sleeping on my sister's bed. He was a big old oaf of an animal, and was probably in there licking himself, panting from the heat, and making noise. God I felt so foolish. There I was, throbbing erect cock in hand, dreaming of actually hearing my own sister fucking her husband, and in reality it was a frigging dog licking his own balls. I grabbed the doorknob, turned it, and burst into the bedroom.
