****** A Question of Definition by groenkaart@yahoo.com ****** =============================================================================== A Question of Definition My stepsister Susan was born out of my stepfather's first marriage, I out of my mother's first marriage. Susan was two years older than I was, and we grew up closely. Her father, a widower then, and my other, a divorcee then, married when she was five years old. Our parents had a very modern outlook in bringing up their children, and we shared a bedroom when we were young. This inevitably meant that we would undress in front of each other, and we saw each other naked on a daily basis with the full sanction and encouragement of our parents - something we thought nothing of, and regarded as natural. In fact, until I was about 10 we regularly bathed together; when our parents were not looking, we would play with each other's genitals in the bath and inspect them to "see the difference." When drying ourselves, Susan often would take my little prick in her hand, feeling it. Usually it did not even stiffen at the touch of her hand, although I enjoyed her doing so. I would on my part marvel at her cute little slit. I particularly remember one day when we were alone together in our bedroom, and Susan took the initiative with "I'll let you see mine if you'll let me see yours" game. She inspected my prick thoroughly, rolling the foreskin right back, whilst I opened the lips of her little pussy with my hand to inspect it. When Susan entered puberty at the age of around 12, her breasts started growing in size, and fuzzy dark hair emerged around her pussy. It was then that our parents decided it was no longer proper for us to bath together. From then on we had to take our baths separately, and each one moved into an own bedroom. Like any brother and sister, we had our fights, but these were rare. Six years went by; I also entered puberty, and Susan grew into an attractive and sexy young woman with a beautiful body, shapely legs, and firm small breasts. I was 16 and Susan 18, she in her last year at high school, when it happened. Our parents went out of town on a business trip for a weekend, and Susan and I were to be on our own. She had just broken up with her boyfriend, and felt a bit down. Neither of us had any social commitments for the weekend. She took out a movie from the video shop, and we watched it together on the Friday evening. Only when some steamy sexy scenes flickered on the screen did we realize that it was an adult video with an age restriction of 21. It was with great anticipation that we continued watching. I felt a bit embarrassed at seeing sex performed on screen, being in the company of my step sister, but was relieved when Susan said after we watched for a long time in silence: "Gosh, it makes me feel horny." I admitted to experiencing the same arousal. "Have you slept with a girl?" she asked, unexpectedly. I told her that I was a virgin in that respect. "So am I, although I have petted. But I do relieve myself regularly," she said. "You mean you masturbate?" I asked. "Of course I do! Don't you?" she replied. I had to admit that I do so regularly as well. "I wish I could see you one day masturbating yourself," she said. "That is something I really would like to watch!" "Well, perhaps I can arrange for a demonstration just for your benefit!" I teased. But the thought made me even more horny, and the prospect of performing for Susan gave me a thrill. It was clear that Susan was also sexually aroused. "When I lose my virginity, it will have to be to the right man," she eventually said. "The time is right for it to happen; I hope it will be soon; I have waited long enough." "Pity you broke up with John, otherwise he could have done it for you," I suggested. "John was not the right man to do it for me," she retorted. "Just tell me if I could be of any service," I replied. Thinking back, it was meant as a joke and quite unintentional. "Don't be stupid. You are my brother," she said. "Stepbrother," I corrected her. After the movie finished we continued discussing sex and the possibility of watching each other masturbate. "I'll show you how I do it if you'll show me how you do it," I offered. She required little persuasion. "That's okay. Let's do it straight away whilst mum and dad are away. We have all the time and opportunity this weekend and nobody will bother us," she said, and suggested that we first take a bath before our demonstration, "just like we did in the old days, for old time's sake." I proposed that we rather take a shower. Perhaps the idea of showering together was meant as an occasion to build up our courage to perform for each other. Anyhow, I thought it a splendid idea as a curtain raiser to a demonstration of masturbation for each other. We went to the bathroom, and undressed. I first thought of helping her to remove her blouse and bra, but decided to let her do it herself, still feeling just a little uneasy and quite frankly not knowing what to do and what to expect. Me unbuttoning her blouse and taking of her bra would have been a bit too erotic for me: after all, we were supposed to merely shower together and then demonstrate masturbation for each other. We took off our clothes and stood naked in front of each other, staring at one another for a few moments, just taking it all in. I looked her up and down; she did the same with me, observing the changes our bodies went through since the last time we saw each other naked. Susan was breathtakingly beautiful and sexy, with well-formed breasts and a bush of dark hair around her genitals. "You have a beautiful body," I complemented her. "You have nicely formed tits." "And you yourself have grown into a very handsome young man. I hadn't fully realized it until now" she said. A few further seconds of silence followed as each anticipated the next move from the other, not quite knowing what step to take next. By this time I had an enormous erection, and at the sight of my naked stepsister my penis grew even more in size. I had never paid much attention to her until now, but seeing her naked since she has grown into a young woman I suddenly realized that she was extremely beautiful, with shapely legs and an exquisite body. I saw her in an entirely new light. Susan broke the ice by commenting on the size of my prick. "Gosh it has grown! I can remember it being just a teeny weenie, soft little thing. And you have grown pubic hairs as well; last I can remember you were as bald as a baby down there!" she said. My penis was still filling with blood all the time, increasing in size by the second. One vein running across my prick stood out noticeably, pulsating with each heartbeat. "It is fascinating watching it grow! May I touch it again like I used to?" she asked. I allowed her to. She reached out her hand and touched my dick. "It's so hard and firm!" was her comment. She ran her fingers over the full length of my manhood, stroking it lightly. "The skin feels lovely smooth!" Susan said. We entered the shower. We both realized that this time it was very different having a bath together as to when we were both six years younger and just kids. As opposed to then, the fact that we were of opposite genders now meant something very different to each of us; we instantly became aware of our sexuality. Things have changed during these past six years. Standing naked under the running water with my stepsister made me as horny as hell. By this time we had no feeling of embarrassment or shyness being naked in each other's company. It was all very natural for both of us, almost like in the old times. "Are you embarrassed seeing me naked now that I've grown up?" I was curious to know. "Not in the least" she said. "I just love seeing your naked body. Your big prick really thrills me to bits. I didn't know it would eventually grow this big. I haven't really seen a man's penis so closely. A grown man's penis, I mean..." I took the soap and began washing her back, lathering her whole body, and pretending it to be accidental when in the process I fondled her breasts and pussy and anus, to which she did not object. In fact, I got the impression that she enjoyed being caressed everywhere. "Oh, it's nice!" she said. Her nipples grew firm and stood out erect. It was fantastic feeling her wet, smooth body in contact with mine. We both laughed playfully under the falling water, enjoying every second of our togetherness. Facing her, my erect penis momentarily touched the entrance to her vagina. I moved my pelvis forward, causing my penis head to push firmly against her body. "No Michael, that is out! No entering! We are not going to fuck" she said firmly. "After all, we are brother and sister, and it would mean incest. We are just having a shower together like we did years ago, and then I want you to show me how you masturbate yourself." I was disappointed, but left it at that; after all, she was my senior by two years, and had a rather dominating personality if she wanted to exert herself! How I would have loved to shove my prick into her pussy there and then! Then she soaped me, lightly washing my penis with both hands, doing it on the feel only and not looking down, but rather staring straight into my eyes. We both cherished the experience. She pulled me closer to her, and I pressed my body hard against her, my penis going between her legs. Standing like that, she put her arms around me and washed my back. I gave her a kiss; it was so erotic! She moved behind me, put her arms around me, and fondled my genitals from behind, stroking my penis and playing with my testicles whilst pretending to wash me, briefly interrupting it to scrub my back with a brush. She stood close, hugging me from behind, as she washed my chest. She turned me around again. "Can I take your prick in my mouth, just for once?" she suddenly asked, as a new urge came over her. "I always wanted to know what's it like sucking a man's cock, like that girl did in the video we watched." Susan knelt down in front of me and took hold of my erect penis. She slid back the foreskin right back, exposing my whole glans, and at first took only the head of my penis into her mouth, not sure what to do or expect. She fed it in a little more, and rolled her tongue over my glans, sucking softly. She pushed it in deeper, trying to swallow my whole dick. I could feel the head of my penis touching the back of her throat whilst her nose touched my body. "I really feel in control of you when I have your dick in my mouth," Susan said taking my penis out of her mouth, and continued sucking for a little while longer. Then suddenly she stood up and said: "Good, that's enough for now. This is not what we are here for, and if we continue like this we will go too far." It stopped far too quickly for me, but she was determined not to continue. Her self-control was better than mine! I got the impression that she was just wanting to briefly sample each and every new sex technique she could think of; that it was a new adventure in which she wanted a little taste of everything on the menu. I decided that I was not going to be left behind and to fully seize the opportunity of practically experiencing some of the delights I have only read or heard about. "May I kiss your pussy?" I asked in return after she stood up. "Go ahead," she said. She stepped out of the shower and sat on the edge of the bath, opening her legs to allow me easier access. I knelt down and opened up her cunt with my fingers, exposing the folds of her young beaver. Her clitoris was bright red and stood out erect like a small appendage. I could smell her sex despite the fact that she had just emerged from under a stream of water; it smelled fresh and young. As a virgin her young slit was small and the lips of her labia were thin. "You really have the most beautiful pussy!" I said. I stuck out my tongue and kissed her pussy, tasting her juices, pushing my tongue deep into her love hole. My nose snuggled in her pussy hair. Far too soon, to my utter disappointment, she again decided that it was indeed enough for now. "Let's get back into the shower," she said. "You have experienced enough for now." I was again amazed at her self-discipline. We spent a good fifteen minutes in the shower, just fondling each other's bodies, alternating it with kisses in between. She French kissed me for a good two minutes in a close embrace. When Susan turned her back on me, I put my arms around her from behind and held her close, pushing my prick between her buttocks. She put her hand to the back, grabbing my penis again, preventing it to enter her from behind. "That's enough! Let's go to the bedroom and get on with our demonstration. I am dying to see you masturbate yourself," Susan said. We dried each other with towels. She could not take her eyes off my penis as she dried it for me, fondling my balls through the towel as she dried them. "You've really grown into a man," Susan said. "You have a lovely prick." "And you have a lovely pussy. I love you, Susan," I said, purposely not addressing her as "sis" as I often did. "I love you too," she replied, giving me a quick kiss on the mouth. After drying, we went to my bedroom, both completely naked. "Who will demonstrate first?" she asked. I volunteered to go first, sitting down on a chair and starting to slowly masturbate my penis. Susan sat on my bed, eagerly awaiting the solo performance, her eyes fixed on my prick. No sooner had I started when she said: "I wish I could do it for you," watching me intently as she leaned forward to have a good look. It was then that she suggested, in stead of giving a performance of self-masturbation to each other, that she would masturbate me, and I in turn would later masturbate her. It was very clear that she would not let things go beyond masturbation. "Okay, but then it is your turn to lie down first," I demanded. She did so on by bed, opening her legs, exposing her pussy to me. Her pussy hairs have grown from the fuzzy down I could remember from six years earlier into a dark patch. "I first want to have a good look at your beautiful pussy. My inspection in the shower was rather superficial," I said. I gently opened her outer vaginal lips with my fingers, inspecting her pussy, this time in closer detail. My face was near to her vagina and I could smell her juices. Gosh, how beautiful Susan's womanhood was! I gently massaged the outer lips of her vagina, moving my finger to her clitoris, making circular movements. Her clitoris stood out erect. I kissed her pussy, licked her labia, pushing my tongue into her little hole as deep as it could go. She squirmed in delight, savoring every moment of it. Susan's pussy was soaking wet and I liked tasting her. With my tongue I played around her erect clitoris, gently sucking it. I started masturbating her slowly with my finger. I pushed the middle finger of my left hand deep into her vagina, masturbating her with my right hand. "Yes, yes..." she urged me as she neared her climax. This went on for a few minutes, until she finally came, squirming in sheer ecstasy. "I'm cummiiiiiing...OH YES! OH YES! Don't stop, keep it up!" She went limp. "I will have to wait a few minutes to recuperate before I masturbate you," she said after it was all over. I gently fondled her breasts whilst she rested, waiting for my turn to be masturbated. We just lay there next to each other for good half an hour. Then at last she took my penis, which had gone slightly limp by now, into her hand, stroking it gently, again taking it into her mouth and sucking. It had the desired effect and it stiffened in seconds. I was lying flat on my back, she kneeling next to me. She took my erect penis in her right hand and began a rhythmic movement up and down, clasping the shaft towards the tip. Her movements would open up the head of my penis on the down stroke, and then again completely cover it with my foreskin on the up stroke. Up and down her hand went. "Hold it harder," I said. She clasped her whole hand around the shaft of my prick. After a while I asked her to stop momentarily, thus extending the process. She did so, saying that she wanted to have a detailed look at my dick and testicles. She bent over and inspected it minutely, with her face no more than a few inches from my genitals, pushing back the foreskin, opening up the little slit at the front of my penis. "Is that where your jism comes out?" she asked. I begged her to continue masturbating me. This time she used rapid up and down movements. My glans grew cherry red, being filled with blood, and I had a hard- on like I have never had before. I could feel the build-up in my testicles. Finally I also came with an intense orgasm. Wave after wave of sheer ecstasy rolled over my whole body. I started ejaculating and my semen landed on her breasts and my stomach in a series of strong squirts. It was a climax like I have never had before. "Gosh, that was quite a load," she said, "I wonder what it tastes like?" "Well, try it," I suggested. She dipped her finger into my cum, putting it in her mouth. "It tastes musky. I rather like it. It tastes of you," she said, licking the remaining drops of semen from the head of my penis. She kissed me deeply, transferring a taste of my cum from her mouth to mine; it was silky smooth. We lay next to each other for quite a while. Then we cleaned up and decided to sleep together in my bed, again in the nude. I turned my back to Susan, and she molded her body around mine. We were both exhausted and reminisced about our mutual masturbation experience. Both agreed that it was the best and most satisfying thing that ever happened to either of us, which we would like to do again. "Do you think it is really incest if we fuck?" Susan asked unexpectedly after I had put out the light. It was clear that the problem was bothering her and that she was exploring the possibility of going a bit further in our physical relationship. "After all, we are not biologically brother and sister, and are not blood related." "I honestly don't know. It is just that we grew up as brother as sister," I answered. We discussed the situation. Of course, if it had not been for the fact that my mother married her father, there would have been no legal impediment to us marrying each other. We decided that although there may be moral and ethical implications, us fucking would only amount to incest technically. All the time Susan fondled my now limp penis. "I wish I could have a penis like this inside my pussy one day, but then it will have to be stiff!" she said. "Only if you hadn't been my step brother I would ask you to do it right now. I would dearly love someone just like you to take away my virginity." "I am in no condition to fuck you right now and will have to recuperate first" I said. We left the topic of incest at that and both soon drifted to sleep. It must have been about six o'clock the next morning when I awoke. It was just starting to get light outside. By this time I had a massive erection again. Susan was still lying behind my back, and I turned around facing her. My movements awoke her, and she quickly realized the state of my dick, feeling it with both hands. "You've got a massive erection again!" she said. "You know, I was dreaming - dreaming that you were fucking me. It was all so beautiful, doing it with you, my step brother." She was all wet down at her pussy. "Don't bring up the brother thing every time," I said somewhat upset. I honestly felt that she was bringing it up as an excuse to prevent us from taking the next step. It stood between us as an unnecessary barrier. I did not want to be reminded of the fact every time that we were stepbrother and sister. "Do you want to put your prick in my pussy and fuck me?" Susan asked after a while. "If I must give you an honest answer, yes I do! But what about incest? We have not resolved that issue as yet," I said. I did not want to do anything with which she may not be at ease with. "Well, its all a question of definition. For example, would you say that I am a virgin?" she asked. "Of course you are! You have not had intercourse with a man before," I replied. "Well, that is the point. My hymen has been pierced a while back by myself, using my fingers, when I masturbated. So if you define a virgin as one having an intact hymen, I am not a virgin. On the other hand, if you define it as a female who has not been penetrated by a man's penis, I am a virgin. Its the same with incest; its a question of definition" Susan said. "You mean if incest is defined as sex between near blood relatives, we will not be committing incest if we make love to each other. But what about incest being defined as sex between members of the same family? After all, we are members of the same family" I said. "Dad and mum are members of the same family, and they are not guilty of incest when they make love to each other" Susan retorted. Her logic impressed me. "So the definition of biological kinship is the deciding one," I said. She lifted herself on her elbows and looked at me intently. "Exactly! We already know that we are not blood related. If you want to fuck me, I myself have no moral or ethical objections and I will let you do so, because in my definition it is certainly not incest," she said. "I want you to be the man to take my virginity, or someone just like you. In fact, I want to make love to you. Please let's do it!" "But what if I make you pregnant? I do not have a condom," I said. "I am in my safe period, about four days before my next menstruation period will begin" she reassured me. "I would dearly love to make love to you as the first woman with whom I do it," I said. "In a sense I will also be losing my male virginity to you then, and I would not like to lose it to anyone else." "Enter me Michael. Put your dick inside my pussy. I want to feel your whole cock inside of me. Make love to me, make a woman out of me," she said, this time calling me on my name and not referring to me as her little brother. She looked deep into my eyes. "I want someone very close, very dear to me, to be the first to enter me. I have decided that you are to be that man." Neither of us said a word again, since we both knew that we have emotionally crossed that thin line that previously served as a barrier between the two of us. Suddenly there were no longer any taboos. Nothing stood in our way any more. We were going to make love, and this was the opportune moment to do it. We continued foreplay for a little while, preparing ourselves. After a few minutes we were both fully aroused and ready for it. I maneuvered into position between her legs, which she spread wide. All the time we looked into each other's eyes intently. Susan helped me by taking my penis, pushing back my foreskin to fully expose the head. It was dripping with my own pre-cum. She guided it to the lips of her wet pussy. I proceeded to gently nudge the head of my dick into her moistness, lubricating my cock with her wetness, rolling it around in the mouth of her vagina. With the head of my cock planted at the entrance to her vagina, I gently moved my hips forward to enter her. At first I did it ever so slowly, and after meeting resistance pulled back a little bit. Susan kept her hand on my cock, guiding it back into her love hole. Although her hymen was not intact, she was not completely pierced as yet and her vagina could not readily accommodate the thickness of my penis. Again I pressed forward with my dick, and each time I managed to go a little deeper. Susan's cunt was very wet with her juices, and as my dick got wet from it I could slip into her a little easier and deeper every time. At last the head of my cock had penetrated her tight opening, but the rest of my shaft still had to follow. "I can feel you Michael. Your dick is beginning to enter my pussy. Please continue to fill me with your cock. I want to feel you all the way inside of me. Come in completely," she said. "Your pussy is so tight and I don't want to hurt you. But it feels so-o-o- o good," I said. "I do not think that your hymen has been pierced completely yet." It was a emotional experience knowing that I was going where no one had gone before, exploring "virgin territory." It was the fist time a penis had entered her vagina, and it was mine doing so. I nudged forward; then suddenly the remaining part of her hymen yielded, and I slipped inside; Susan had been completely pierced! We have both lost our virginity simultaneously. My dick felt good inside her warm and wet and very tight pussy. I just wanted to lie there and enjoy how it felt, but still had about four inches more to bury, so I pushed in very slowly, withdrawing a little each time and then penetrating a bit more on the next gentle forward stroke. Our movements were as if in slow motion. I told her to relax, and found that my cock could slip a little deeper into her cunt when she did. Little by little I was finding that I would have to pull back further on each backstroke because I was now almost completely inside her. Susan felt it too, and her breathing became stronger. I was fondling and licking her firm breasts, making little love-bites on her hard erect nipples, kissing her on her mouth and in her neck, concentrating hard on my dick which was now almost fully into her womanhood. "Oh Michael, your cock is filling my cunt. It's so big. It feels so good. It's so warm and hard," Susan said. On my final thrust I slipped all the way inside. I could feel the tip of my penis touch her cervix, or entrance to her uterus at the bottom end of her vaginal canal. We were a perfect fit. I lay still for a while, cherishing the moment. We have done it! I felt Susan's warm cunt tightly wrapped around my penis, holding it ever so firmly in a warm embrace. I was into her completely, our pubic bones pressing against each other hard, my testicles touching her body. A few minutes went by with me just wanting to enjoy this moment of having penetrated my stepsister for the first time. We felt incredibly near to each other both physically and emotionally. I embraced her and gave her a long kiss, and she put her tongue into my mouth and French kissed me. We lay completely still, me on top of her, firmly coupled. "Why did you stop?" she asked after a while. "Because I just want to feel you completely," I said. "I want this to last forever..." "Carry on, let's finish it," she said. I began to pump slowly inside Susan's cunt, making short thrusts now that I was fully inside her. She closed her eyes and said: "Yes, Michael, yes, yes, yes. I love your big cock inside my pussy. Don't stop fucking me. Carry on, it is so lovely." It was becoming easier to slide my dick in and out of her vagina now that her juices, mixed with my own pre-cum, became more abundant. As we continued, Susan was nearing a super climax, feeling my hot rod ramming her equally hot pussy. "Oh Michael, I am starting to cum with your dick inside me. Faster! Faster!" With that she came. She squirmed and grunted and screamed out loud, thumping her pelvis against mine. "Yes, yes, yes!" she shouted. I likewise felt the buildup in my balls and held back my orgasm as long as I could, thrusting deep into her with our pelvic areas pushing tight against each other, until my cock literally exploded inside Susan's vagina. I pumped furiously as I felt my sperm squirting against the walls of her vagina. Her cunt was now very wet with the mixture of her cream and my ejaculate. We stopped movement after what seemed a very, very long time. We were both exhausted. I laid still on her, trying to catch my breath, with my penis still inside her pussy, not wanting to withdraw it. We rolled over on our sides, still firmly locked. After about fifteen minutes my cock subsided and went limp, and it slowly slid out of her. "Thank you, Susan. That was the loveliest experience of my life," I said, kissing her deeply. "I feel elated. I never thought the first time would be like this and that sex could be as good as this," she said. "I always heard that the first time is painful, but you did it so gently that even this very first time I made love it was just marvelous." We fell asleep again cradling each other in our arms, and the sun was high when we finally awoke a few hours later. We got up and showered together. I felt a deep feeling of attachment to my stepsister, having shared one of life's most intimate experiences with her. I would not have liked to lose my virginity to anyone else and under any other circumstances. Under the shower we kissed intimately. My hard prick again landed unintentionally on the entrance to her pussy, just like the evening before. This time she took it in her hand, and directed it into her vagina, and I entered her. I easily slid my penis into her pussy, which was well lubricated from my own cum and her own cream. We stood still like this under the running shower for a long time, - just keeping my penis inside of her, holding her very tight against my body, kissing her. Then we fucked each other under the shower till both came. We fucked twice again later that same weekend before our parents came back on the Sunday evening, and both were a little bit sore afterwards. The third time she wanted to be on top, lowering herself onto my erect pole at her own tempo. She completed the act beautifully whilst I fondled her breasts. "And how did you two get along this weekend?" my mum inquired after she arrived home. "Were you fighting with each other again?" "No mum, Michael and I had a lovely weekend, and one which we will never forget" Susan answered. "I think our fighting days are over. We have grown up." Susan and I made love again a number of times after that weekend, whenever the occasion presented itself. A few times she would slip into my room late at night when our parents were asleep. As their bedroom was at the other end of the house, far removed from our bedrooms, we could fuck each other without fear of being caught. Only these times she could not raise her voice and shout when she experienced her orgasm, like she did that first weekend. I always appreciated these occasions, realizing that she wanted and needed me. We made sure to use condoms during her unsafe periods so that she would not fall pregnant, although it never felt the same as when I did it with my naked penis that first time. When she was certain that she was in her safe period, we made love without a condom. "I like to have your cum inside of me," she said these times. After the end of that year she went to college, and our regular intimate meetings came to a temporary end. A few times during each of her college holidays we again made love, before she found a boyfriend and I a girlfriend, and we stopped fucking each other totally. There is a bond between the two of us that extends beyond family-ship, and now that we each have our own families, we cherish a shared secret whenever we meet at family gatherings. During such times the two of us would make certain of sharing a few moments on our own, and I would say, "Remember?" Susan would always answer: "Shall I ever forget!" and kiss me. She is a special woman. Comments to: groenkaart@yahoo.com This story is part of White_Shadow's_Nasty_Stories. You may also want to visit: * Sexy_Top_100_Stories * Erotic_Top_100_Story_Sites
