About the time I was 16 or 17 years old I was increasingly becoming aware of the odd feelings of attraction or infatuation whatever you want to call it towards my then Auntie Diane. I suppose during these years all young males go through some sort of infatuated crush towards an older woman I just didn't expect it to be incestual. At this time I worked stacking shelves at a local supermarket, coincidentally Diane worked there as a checkout girl so regularly we would meet up after work and give each other a lift home. This was when I realised that my feelings were on the brink of becoming dangerous for the stability of my family as we were all very close, I couldn't say or do anything as it would destroy the already close relationship I shared with my aunt. Whenever Diane would drive me home I would sit there in the passenger seat, hopefully guarded by the darkness lovingly trying to catch a glimpse of her beautiful boobs and hope the for some strange reason she would pull over, turn off the headlights, turn to me and openly admit that she was feeling what I was feeling but alas this never happened, I just had to be content with brief glimpses of the top of her bra as she bent over to pick things up or to watch her ample arse swing as I would follow her in to her house. The relationship we shared was particularly close or so I thought, most weekends Auntie Diane and My uncle would invite me to stay over where we would often spend the evenings drinking, chatting and generally chilling out, this often gave me the chance to observe Diane at close quarters as she would never catch on that I was staring as the alcohol usually numbs sensor responses, so I stare to my hearts content wishing for the chance to unzip her top and tenderly massage and caress her ample cleavage. On one particular occasion My uncle had to leave for work around 10 PM to work a night shift, Both Diane and Myself had been drinking so we were both in a state of laughing and giggling. He said his good-byes and left us to our bottles of beer and the increasingly boring TV As the night progressed Auntie Diane was nodding of to sleep whilst the T.V blurted out mind numbing crap that nobody in their right mind could consciously enjoy, subsequently she fell asleep slumped out across the sofa, was this going to be my chance? As I held my breath with both anticipation and sheer dread I stared at Diane as she drifted off heavier and heavier into a deep slumber, by this time my penis was becoming increasingly hard, hard to the point that my jeans were becoming uncomfortable so I decided to undo my zip and realize the pressure, let him flop out to stop it hurting because of the constriction. Thoughts of fucking my auntie were racing around my head, do I don't I etc etc. I decided that for the sake of my sanity and that sanity of my fammily I would slink off to the bathroom penis in hand and wank myself stupid at least nobody gets hurt when the disgustingly erotic thoughts are only in your head, so I pumped away until torrents of hot white lava flowed and pumped all over the place wishing that at this point Diane was convulsing in an almighty orgasm and her cunt was over flowing with my love juices. I returned from the bathroom to find her still asleep, asleep to the point where low snores were emanating from her breathing, I still couldn't get the thoughts from my head, so once again the ponders, the questions and the almost instantaneous erection all reappeared. I stared and stared for what seemed like 5 hours, it was probably only 5 minutes but my sex drive got the better of me, I tip toed across the room holding my breath, not making a sound and knelt down in front of her whilst she lay sleeping, the butterflies in my stomach were becoming unbearable, I ever so slowly reached out my hand and gently laid it on her left breast. Through the materiel of her blouse I couldn't feel much except the shape and the size of them, What was I doing, I was fondling my Auntie Diane's breast, admittedly her clothed breast but her breast none the less. I needed more I carefully reached for the top button on her blouse; it opened much easier than anticipated revealing the nicely tanned upper portion to chest ant bottom of her neck. Boldness was now taking over, I casually leaned over and kissed the bottom of her neck sucking gently as I tongued this forbidden flesh Suddenly my heart sank into my jeans as Diane abruptly stirred letting out a little moan, did I do that or was she simply dreaming, I jumped backed and glued myself to my seat to see the reaction, to my sheer relief Auntie D had only stirred in her sleep and was by now well on her way back to the land of nod, I decided that I had gone a step too far and decided that I should right what I done wrong, I carefully went to button up the top her blouse, To satisfy just one more craving I took a glance down her top just before I was to button it up....definitely the wrong move. In the dark recess of Auntie Diagnose blouse I could clearly see that she wasn't wearing a bra, at last I had seen her beautiful tits in full, and what tits they were, especially for someone knocking on 35 and a daughter to show for it. They were more than a handful beautifully round and pert, more like 25-year-olds than my Auntie's own. This wasn't enough, my now granite like erection was doing all the thinking, I clumsily opened the rest of the blouse buttons and untucked it from her jeans, I had gone past the point of no return, I would never be able to dress her again without waking her up. There they were, in broad daylight, well light from the ceiling lights anyway. My auntie's tits were on full view. By this time all my senses had gone into overload, I was faced with a potentially awkward situation, but there in front of me were the loveliest pair of big tits I had ever seen I just couldn't help my self, I clumsily grabbed on to them a lapped and sucked with all my might. To my amazement, Aunt D's nipples grew and hardened so as I caressed her lily white, velvet soft tits I lapped, sucked and chewed on her increasingly stiffened nipples. All off a sudden a hand come crashing around the side of my head sending rings down my ear as Diane shot up out of the chair tits in hand screaming "what the fuck do you think you are doing", " your uncle will go fucking ape shit when hears what you have been doing" scared senseless I blurted out a sorry as she raced up the stairs heading for her bedroom. My mind was in turmoil, what should I do, I sat there for about an hour pondering what I should do, say or to a degree not say. I plumped for going upstairs and knocking her door, in the hope she would see it as a careless accident caused by the racing hormones of an 18-year-old. Carefully I knocked and asked Diane If she was O.K, "yes" she mumbled, "go away". I knocked again, "can I talk to you, PLEASE" I emphasized, "about what, haven't you done enough" Diane muttered. I told her that I was awfully sorry and I just wanted to explain what happened and why. "I will be down soon" she ordered, "wait down stairs". I waited for what seemed and eternity, then there she stood, eyes still bloodshot form crying, just wailing "why", "what for". I set about telling her about my infatuation and how it was screwing up my head I thought honesty was my only savior at this point, Diane listened to what I was saying to the point where my embarrassment took hold and I bleated like a child, sobbing "sorry" and "please forgive me". That seemed to do the trick, Diane leant over and gave me a reassuring hug saying she understood why I did It and that she knew she had nice tits but what I had done was wrong, incestuous she said. " If had opened up and told me we could have talked through it, I though we could talk to each other" she said. I apologized once again and said I was going to bed, I tossed and turned for hours contemplating what had happened, part of me regretted it, the other, most probable the part that controls the groin was in a state of euphoria, every time I pictured Diane's tits I got a raging hard on, so much so that I decided the only way to release it was to wank myself off to relieve the tension. For 10-15 minutes I pumped and stroked until to amazement there stood Diane in the open door. " I thought you had just got that out of your system. " shit " I shouted, " no worries" auntie D said as she came over and sat on the bed. Just as quickly she threw back the duvet and stood back in amazement, "seen as though you have seen me I think its only fair I see you", "excuse me" I blurted, Diane replied with "I thought about what you said and I think the best way is to hit it head on, I we have sex then you will get it out of your system and we can get back to being Aunt and Nephew", " what do you think" she muttered. " I guess so" I said to cover up my sheer amazement at the prospect of actually fucking Diane here and now. With that comment Diane leaned over, looked up to me and as quick as a flash took the whole of my shaft into her hot mouth, she gently sucked and lapped as my pre cum gushed out. "Not bad" she mumbled whilst still blowing me senseless, just then I pulled away as the first feeling of an orgasm were about to hit, "no I m in control" Diane ordered as she took, me back in her mouth. I couldn't hold on, the flood gates opened and I gushed what seemed like gallons of hot cum right down the throat of my Auntie Diane, It trickled out the corners of her mouth as she swallowed all she could without choking, "hmm tasty" she said as she gave me a wry grin. Just the Diane asked " would you like to undress your auntie" without a hesitation I ripped open her blouse, buttons flying everywhere, and out flopped her luscious love mounds, she the casually dropped her jeans the her pants and stood there in front of me butt naked apart from a pair of stiletto high heeled shoes. "Right, nephew" she ordered "get naked and take it away, fuck your auntie till she comes" she said. I never expected her to utter words like that, but with that order I was naked and erect in the time it takes to blink Diane lay on the side of the bed and opened her legs showing off the one area I never thought I would see I just stared into her cunt as if I was hypnotized by it. I carefully rolled over and straddled her letting my cock rest on her sweating belly, I leaned down and caressed her tits taking in every inch of supple baby soft flesh as I licked and fondled. I grabbed her legs and pushed the back towards the bed head and made a forceful dive towards her cunt, my rock hard penis sliding down a well lubed tube much to the delight of Aunt D, she let out a scream, I shockingly asked her If I had hurt her, yes she replied but it was "nice pain" don't stop she panted, I viciously reamed away at her dripping cunt until Diane exploded into a body rippling orgasm, screaming her head off, withdrew just to watch the unbelievable expression on the face of the totally nude, 35 year old woman whom I had just used and abuse so to speak. On that note I rolled her over lifted up her chubby ass and parted her lips with my hands I bent down taking in the musky aroma of my auntie's pussy, licking and sucking all I could triggering to my surprise yet another blood curdling scream of orgasm. Whilst Diane was lying there with her arse in the air I caught a glimpse of her puckered ass hole, thoughts were raging through my head about fucking a woman up her arse, this was my chance I cautiously took the head of my rock hard knob and gently pressed on her arse hole, to my amazement, she pushed back causing the temporary swallowing of my purple head in to the first inch ors of Auty D's ass I withdrew to see what the reaction was. Diane immediately said, come on the fuck your auntie's arse till it wont take anymore fuck, I pushed at her hole and the head went in, she let out a little scream of pain saying " i have never been ass fucked before, ram the fucker in don't mind my screams, I did just that forced it in as deep as it would go, Diane was screaming in agony as I had just pushed 7 inches of rock hard cock right to the bottom off her arse tube in one go, god it was tight. I waited a second for the muscles to relax, I took a glimpse of my Aunt, tears were rolling down hear cheek, I asked her what was wrong she said "I have never felt pain like that, It was intense but the sort of pain I like","get my ass fucked, fill my bum with your cum," on that not I started pumping her tight ass, she was now moaning and panting like never before, I suddenly felt a cum coming on so I warned her, grabbed her arse cheeks and pumped a gallon of cum into her ass. I rolled off my aunt as soon as I had gone limp, she stood up above me with cum dripping from her bright red, sore arse as she calmed down and stopped panting. I couldn't go on anymore's I was all fucked out, so Diane and I had a passionate kiss and she left the room, calling back in to whisper "thank you". From that day on we never spoke about our night of discovery and we never had sex again, I guess she was right I did get it out of my system.
