Their New Mother: Part 1 Betty was cleaning her father's room when she knocked the picture off the side table. She was horrified. The picture was of her mother and Betty was afraid that she had ruined the only remaining memento of her. She knelt and gathered the broken glass and found that the frame had come apart at the corner. She carefully lifted out the photograph and the backing papers to set them aside while she cleared up the mess. After putting the broken shards in the dustbin Betty finished straightening the rooms simple furnishings and put the clean clothes away in the bureau. She enjoyed looking after her father and now that she was twelve years old Betty felt as if she were the woman of the house. But she was afraid that she was not to be for long. Father had left she and her twin brother Billy to look after the family store for a few days while he met with a woman with whom he had been corresponding. Her father had been alone from the time she and Billy had been born. Mother had died in childbirth. He had raised his children alone but now it seemed that he wanted someone else. Betty couldn't understand why. Betty fussed about the room and then worked up her courage to deal with the picture. Perhaps she could reassemble the frame without glass and no one would notice, or she might go down stairs to the store and see if she could find a replacement. She thought that she could tell father she had decided on a better frame if she found one. When she picked up the photograph Betty noticed that there were several sheets of backing, surely too many. Separating them she discovered that the other sheets were more photographs. After quickly looking through them Betty sat heavily on the edge of the bed. Her young mind was spinning and she felt very strange, almost light headed. Slowly she again separated the sepia photographs laying them out on the bed cover. It was difficult to focus on each one. She had never seen anything like the images shown there. A young woman was shown without any clothes on, her entire body exposed. Betty could clearly see the firm young breasts and even the woman's private thing. The beautiful woman sat posing for the portrait before a curtained background, her long hair hanging loose, her slim body proud and straight as she seemed to hold her naked breasts out. Her legs were wide giving a clear view of her bare privates. The most astounding aspect of the photograph was that standing beside the naked woman was a naked man. That man was Betty's father. He was clearly younger and stood tall with his arm resting on the back of the settee. Betty looked at her father's young naked body, her attention riveted on his groin. She had seen many horses as they stretched out their huge organ to pee. She had even seen horses mating and noted the hard member as it entered the mare. But this member belonged to her father and it too was long and hard. The young couple looked happily at her from the photograph as if it were the most normal thing in the world to be seen naked. Betty suddenly realized who the pretty woman was and picked up the treasured photograph of her mother and compared them. Yes, they were the same. Her mother's hair hanging down lose had made her look very different. Here was her loved mother and loving father, both smiling and happy and naked. As Betty looked through the remaining pictures she was confused about what was being shown. There were more pictures of each of her parents standing or alone seated on the settee in much the same pose. Each was shown sitting straight with legs open to show all of their naked bodies. One of the pictures of father showed him grasping his hard member in one hand as he cupped his testicles in the other, one leg over the low arm of the seat. Mother was shown in the same pose as she held a firm breast in one hand and seemed to have fingers inside her woman's part. The last photograph was to Betty the most surprising of all. Father was seated at the end of the settee and mother was beside him with her legs spread over him. Betty could clearly see that father had his hard member inside mother as she faced forward and he held one breast as he reached around her. However they were not alone. Another younger woman sat at the other side of mother. She was naked also, her legs open to show that Betty's mother was touching the woman's privates. The strange woman held mother's other breast. The two women were kissing as father looked on with a big smile on his handsome face. Betty didn't know what to think. Why had her parents been photographed in this manner? Who was the other woman? When had these pictures been made? Who had taken them? Not least of all, why did looking at these pictures of her naked parents make her feel this strange way? Betty felt warm all over her young body. She had a damp feeling in her drawers. Betty gathered the pictures up and placed one of father on top of the stack. She fell back on the bed and held the stack up over her and studied the photograph. She looked carefully at father's hard member and images of horses mating kept coming to her mind. She imagined that she could see father before her naked and holding his hard member for her. She wondered what it would feel like to touch it, to hold it the way father did in the picture. Betty looked at the picture of her naked mother touching herself. She looked closely at the woman's features and could see herself there. Would her own breasts ever fill out to look like her mother? She ran her hand over the low mounds on her own chest feeling the hard nipples pushing against her thin dress. Slowly as if she were afraid of what she would find, Betty lowered her hand to her stomach. Lower. She cupped the slight bump there and squeezed where it was throbbing. Her body seemed to explode from beneath her hand. She curled up in a convulsive spasm as waves of pleasure washed over her. Each wave brought flashes of heat and her breath brought her no air. Her head spun as light flashed about her. Presently she lay in an exhausted sleep. Betty awakened to a darkened room and the sound of her name. She was disoriented and at first didn't know where she was. Suddenly realization came over her and great embarrassment when she heard her brother's voice calling to her as he came up the stairs from the shop below. In her haste to gather the pictures she again dropped the frame to the floor this time breaking it completely. "Betty? Sis? Where are you? I've had to close up without you. What are you doing?" Billy called out as he came in the door. Hearing the crash of the frame in his father's room Billy went directly to the door. His twin sister was on the floor gathering papers and wooden pieces and seemed upset. "Betty didn't you hear me calling you? What's wrong? Where were you?" he asked as he looked about the room. "I had to close up without you and you know I don't know how to check the till. Not that it matters much, I don't think anyone was in all afternoon. What are you doing?" Betty finally gathered up the frame and the pictures and stood. She tried to keep the look on her face neutral and the things in her hands hidden. Her efforts only made her look more uncomfortable. "I was just putting the laundry away and straightening father's room. I'm sorry, I guess that I didn't notice the time." She mumbled. "That's alright Sis, I just didn't know what to do with the till." He said looking at his sister's strange expression. Something was amiss he could tell. "What's all this then?" pointing to the jumble in her hands. Betty knew that she could never hide anything from her twin. They were much too close. They had grown up being each other's best friend and companion. Father had moved them many times, always seeming to look for some better place. Searching for something or someplace. As a result the twins had made few friends and relied on one another. She again collapsed on the edge of the bed and with tears flowing began to tell Billy what she had done. "I didn't mean to break Mummy's picture, it just fell. And then I couldn't fix it and I found all these other pictures and I didn't know what to think and she was so pretty and I saw that she was naked and so was Daddy and I felt so strange and I looked and looked at them and I don't know what to do. Oh Billy, it's mother." She cried. "What pictures?" Billy asked, "Who was naked? What are you talking about?" Betty silently handed her brother the pictures as he sat beside her. She gathered a handful of her dress and wiped away the tears on her cheeks as she watched Billy begin to look through the photographs. With each new picture she flinched and looked at Billy's face afraid that he would be upset or angry with her for making this discovery. Billy kept looking at them and going from one to another. She could see that her brother's face was intent and he studied each picture. "Well, what do you think?" Betty asked quietly. "That's really our mother." He said. "She's beautiful. I've never seen naked tits before and hers are wonderful. And look at her cunt. You can see her cunt. She's showing it to us." Betty had never heard her brother talk this way. She had heard some of the words from overhearing others and the whispers of children pretending to be grown up. But on the other hand she didn't know if these were not just as proper for she knew no other names. She began to ask her brother about how he knew of such things. Making the best of a chance to show his sister how worldly he was Billy went through the pictures and explained to her about the various parts of their parent's anatomy. Of course most of what he knew was remotely learned and Betty had seen just as many animals mating as he had but some how having her brother tell her of these secrets was much more informative and exciting. When Billy explained about father's hard cock and what he was apparently doing for himself Betty questioned him. "Is that what you do?" she asked, "Can your... cock... get hard like that?" "Of course I can get hard. All men can." He said indignantly, but uncomfortable that perhaps his sister had already noticed how hard his cock was now. "But do you pull on it as father was doing. You said he was pulling on it. Frigging it. Do all men do that too, do you?" Betty asked with obvious interest. "Well sure they do, when they can't fuck. I've done it lots of times." He bragged. Betty looked intently at her brother and felt the same strange feelings that thinking about father had given her. The pictures of her naked parents had already started the dampness in her drawers and her brothers frank talk about sex had fairly made her feverish to the touch. She could see that Billy was having strange feelings as well, his face showed red and he seemed restless as he sat next to her on the bed. "Show me!" she blurted out. "Please, let me see!" Billy didn't know what to do. His own cock was just as hard as the one shown by his father in the pictures. It was exciting to see their parents naked but to stand before his sister and frig his own cock was another matter. Then he thought about seeing his mother's naked body, her bare breasts, her open cunt and an idea came to him. "Alright," he said, "I will. But you have to do it as well. We'll both take off our clothes. It's only fair that I get to see you if you get to see me." At first Betty was shocked at Billy's suggestion but then quickly she became intrigued. She shyly nodded her head but continued to sit on the bed. Billy got up and began to remove his shirt but stopped when his sister hadn't moved. "Come on, you too," he smiled, "it's alright. We'll do it together." Slowly Betty stood by the bed and began to unfasten the top of her simple dress. Both twins watched the other as their clothing loosened. Billy's shirt was tossed on the bed and he unbuckled his belt and began to unbutton his pants as he watched with wide eyes when his sister's dress slowly fell to her feet. Betty stepped out of her dress and reaching for the hem of her chemise began to pull it up. She stopped when she arrived at the bottom of her drawers embarrassed to go on but also struck by her brother's display. He had removed his pants and Betty could see his under drawers tented out in front of him. Billy looked at his sister's slim legs and then noticed that she was just looking at him. He laughed and motioned for her to continue. He stood in only his drawers and watched as his clearly embarrassed twelve year old sister raised her chemise over her head and tossed it on the bed with his shirt. Betty reddened as her brother looked at her small naked breasts. Her pink nipples were hard and stood out from the pale ring around them. Still being young and small they did not hang down but stood out firm and round like little apples. Billy was sure that this was the most exciting day of his life. Even as close as they lived he had never seen his sister naked before this. She was beautiful he thought, just as beautiful as the picture of their naked mother. Neither of the twins knew what to do with their hands as they stood before the other half naked. Billy seemed to be more aware his sister's discomfort and in an effort to reassure her he smiled and putting his fingers in the top of his pants pushed them down. His hard cock sprang free and actually snapped back to slap his stomach. This broke the tension for Betty and she laughed a girlish giggle. She stared at her brother's cock as it stood out. It was long and hard and seemed to glow red with a purple head much like a mushroom. It looked so shiny and smooth and wet at the end. Billy had almost no hair around his cock and his balls, as he had named them, were tight against his cock. "Sis?" Billy said interrupting his sister's study. He placed his hand around his cock and stroked it as he said, "It's your turn." Betty looked into her brother's eyes and could see that he was pleased. She took a deep breath and quickly untied her drawers and pushed them down. Not even stepping out of them she stood straight and still afraid to move for fear that she would lose her nerve and run to hide. Billy looked at his twin sister's naked slim body. Her little breasts rose and fell as she breathed hard making the tiny pink nipples even prettier. Her waist was thin and flat and her hips still boyishly narrow. The center of his attention was Betty's pussy. There was the tiniest bit of light almost invisible hair at the top but he could clearly see the pink puffy fold of her womanhood. He had the most surprising thought as he looked at the pink fold, that it looked very like Betty's lips and deserved to be kissed. "Sis, you're beautiful. You're just as beautiful mother in the pictures." He said in a hushed voice. Betty burst into tears and rushed to her brother and threw her arms around him kissing his cheeks in kisses wet with tears. It took only moments for both to become aware of the warm naked body pressing against them. Billy felt his sister's hard nipples like fingertips pushing into his chest. Betty was suddenly aware of the hot hardness of her brother's cock being mashed between them. The youngsters quickly stepped back almost over come with the need to continue the embrace. Betty laughed nervously and crossed her arms under her tiny tits causing them to fill out. She looked at her brother with complete love, not sure what to do next but knowing that she wanted more. At this moment she had never felt so good. She was sure this is what love was, complete openness and sharing. The very good feeling, yes the wonderful feeling of freedom in nakedness and the excitement of newly aroused parts of her body. There was a warm glow building in the pit of her stomach, which she realized was actually coming from between her legs. It felt warm and wet and wonderful. She felt the edge of the bed behind her legs and sat down crossing her legs to keep in the wet feeling. Billy had kept looking at her and she realized that he was holding his cock. "You promised to show me how you frig your cock." She laughed at her sudden fluency in using the words Billy had explained to her. Billy proudly came to his naked sister and stood before her as she sat on their father's bed. He looked down into her adoring eyes and began to pull his cock in long strokes. It was already dripping from the end and his hand was wet as it slid up and down. He looked at his sister's tiny tits and the bare side of her body thinking that she was completely naked in front of him. Betty leaned forward and watched as her naked brother stroked his cock for her. She could see the clear drops forming at the little hole in the end and was fascinated by the movement of Billy's hand and his hard cock. She watched him work his member. Her hand kept up the rhythm sliding back and forth on her leg. Betty looked up into Billy's eyes and reaching her hand for his cock he understood her request. He released his hold and his sister grasped his cock and began to stroke it for him. She had barely begun when he felt the rush of fire in his groin and with a gasp he erupted. Her brother's cock felt hard and hot in Betty's hand as she grasped it. It was wet and slick from the clear oil dripping from the head and her hand freely slid up and down it's length. She was just about to ask her brother if she was doing it correctly when Billy let out a gasp. Suddenly her face was covered in wetness. Warm fluid ran down over her nose and lips. Releasing her brother's spurting cock she screamed out to him and covered her face turning it away. Billy couldn't stop cumming. When his sister let go of his cock he instinctively grabbed it and kept pumping it to release the wonderful flow of his orgasm. He had never cum so hard in his young life. He fell exhausted beside his naked sister on the bed, unaware that she was crying. Betty picked up her brother's discarded shirt and used it to wipe her face thinking that he had somehow pissed on her. But the smell of the shirt as she wiped her face didn't seem like it. She put down the shirt and with a finger hesitantly wiped away a bit at the corner of her mouth. She could see that it was white and creamy and the smell was not unpleasant. She carefully licked at the wet spot on her lip and discovered that the flavor was sweet and pleasant as well. She turned to chastise her brother for wetting her face and saw him collapsed beside her on the bed. Betty looked down at her naked brother and knew that she could never love another as much as she loved him. She looked down his hard young body so smooth and firm. His cock had lost its hardness and was much smaller, looking soft and different. There was still a drop of white cream clinging to the end. She looked to see if Billy was watching and his eyes were closed. Hesitantly she put her finger out and gathered up the drop and again looking at her brother's face she gently wiped the wetness on his lips. She then lay beside him and studied his face and often found her attention going to his flaccid cock. Presently Billy roused and licked his lips, which caused his sister to giggle. He opened his eyes to find Betty looking intently at him. She slowly leaned forward and put her lips on his kissing him. "I love you." She whispered "I love you," He replied, "and thank you. I've never cum so hard. No one else ever touched my cock before. It was wonderful!" "You got my face all messy. I was afraid you had peed on me." Betty said in mock sternness. "I'm sorry Sis, I couldn't help it. It felt so good when you touched me. Would you do it again?" Betty lifted up on one elbow and looked down at her naked brother. She reached out and grasped his cock, holding it as she had done before. It just fit in her hand lying across the palm, but she gave a gasp as it began to move and swell in her hand. It grew bigger and harder as she watched. She was delighted and laughed and again kissed Billy's lips. She began to frig him once more slowly pulling on the hard length. Billy looked down at his sister's hand on his cock and sighed. He put his hand over Betty's little tit and squeezed. She gave a start but then leaned into his hand and kept stroking his cock. Over the next minutes the twelve year old twins began to accept the touch of the other on their naked bodies. Billycaressed his sister's breasts and played with the hard pink nipples. They often kissed. Betty stopped stroking her brother's cock to lift his balls in her hand and feel them roll in their sack but soon went back to pulling his wet dripping cock. The effect of so much attention soon had its natural result. Billy gasped out to his sister that he was about to cum again and she kept up her rhythm but leaned back out of the line of fire. She was rewarded with a good view of the charges of white strings as they shot out of her brother's cock to land on his chest and stomach. His hips bounced as he forced his cock into her hand and he pulled her to him, his mouth seeking hers. The kiss and the throbbing cock in her hand sent her own body into another convulsive orgasm. When the twin brother and sister awoke it was dark and they cuddled their naked bodies together as they lay in father's bed. Being a typical young boy Billy announced that he was hungry and Betty replied that she would find them something to eat. When his sister began to dress in the dim light from the street lamp Billy stopped her. He went to the window and pulled down the curtains and then lit the bedside lamp. "I'm going to shut all of the curtains," He announced "let's stay naked. I want to see you walk around the house with out any clothes on, I like to look at you this way." The two youngsters closed the curtains and lit the lamps. Betty prepared food for them and they found themselves moving about in what was an ordinary place. Yet it felt completely different, being naked. Billy watched his sister as she walked about, her bottom cheeks bunching as she moved, getting peeks at her tiny puss, her firm little tits barely moving. Betty looked often at her naked brother his hard again cock bouncing as he walked. They touched as they moved around, brushing an arm or holding hands briefly. When Betty stopped in the middle of the room and put her hand around Billy's hard cock, he put his hand on her puss. She gasped at his touch and embraced him, her hard nipples pushing into his chest. Billy felt the tremor run through his sister as he cupped her wetness in his hand. Some how they found themselves back in father's bed, the room brightly lit. Betty laid on the bed with her legs spread as wide as they would go while her brother knelt between them and examined her open pussy. He touched it gently and opened the lips to see the pink wet folds. He looked carefully at the tiny opening hidden there and put the tip of his finger in. Billy slowly worked more of his finger in and opened his sister's pussy. Soon his wet finger was sliding in and out. Betty could not believe that her brother's finger could go so far into her and Billy kept pushing more and harder. His hand felt wet and wonderful on her pussy and when he had pushed in as far as he could it caused her to shudder and tingle all over. His naked sister was bucking against his hand as he fucked her pussy and he cold feel the tremors go through her slim body. Sensing that Betty was about to cum just as he had Billy leaned over her and kissed her lips hard. This caused her to lunge against his hand as she gasped into his open mouth and he could feel warm wetness cover his hand. Betty continued to force her pussy onto his fingers causing them to mash a newly dicovered spot of intense pleasure above his thrusting fingers. Then the world went black as she fell through flashing lights. As Betty roused awake she could still feel her brother's naked body on hers. He was kissing her cheek and he moved against her. She could feel his finger inside her and it seemed so much bigger but so much better. She pushed her hips to meet his and accepted the hot sliding movement inside her and turned her face to his to find his lips. The two panted in unison with their movement and as their open mouths met they found the other's tongue. Kissing and panting and licking tongues built a huge wave of emotion in both the brother and sister. Betty raised her head and looked down at her brother's hand at her puss and saw that it was not his hand. Billy was fucking her with his hard cock. He pumped in and out and her hips lifted to meet his of their own will. She looked up at his face over her and the wave broke over them drowning them both in floods of cream and clear nectar and love. That night was spent in short naps. One or the other of the twin brother and sister would wake and begin to fondle the other. Soon both were awake and Betty would pull her brother's hard cock into her excited puss and they would again fuck until they passed out from exhaustion. The next morning they awoke late and realizing that the store was not open Billy grabbed his clothes and ran down stairs. Betty gathered her own clothing but having tasted the joy of being naked about the house decided not to dress. She bathed and made father's bed where they had spent the night. She felt as if she were floating as she moved about doing household things. Betty began to get an understanding for the joyful satisfaction that she saw in the faces of her naked parents. Happy nakedness she thought. When the light chores were done she fixed a simple breakfast and ate her share. She then reluctantly chose a clean dress and started to dress. It felt suddenly confining to put on clothing so she decided to change the way she had always dressed. The slim young girl put on only her simple blue dress. She left off her chemise and her knickers and felt very naughty to be naked under her dress. Setting out things for her brother Betty then went down to the store. Billy was sitting behind the counter with a wistful look on his face. Betty told him that she had fixed some breakfast for him and put out clean clothes. Billy came to his sister and put his arms around her but Betty quickly pushed him away, afraid that some one might see them. Billy assured her that there hadn't been a single customer in. She allowed him then to embrace her returning his kiss with her own tongue. They parted slowly as the passion of the night before again started to surface. Betty reminded her brother that his meal was getting cold and that if he wanted he could bathe and rest, as she would take care of the shop. Billy started up the stairs and turned to look back at his loving sister. Betty smiled and told him that she would close early if there was no business and they could rest together. Billy laughed saying that he doubted if they would get much rest that way. With a gleeful twinkle in her eye Betty replied that she hoped not and with a daring she did not know that she possessed slowly raised the hem of her dress until her brother could see that she wore no drawers. Billy stood on the stairs and looked on as his sister showed him her naked body holding her dress at her shoulders. He had never seen anything so daring or so wonderfully exciting. He looked out the store windows and saw that no one had seen. With a laugh he then opened his trousers and stepped out of them. Betty gasped as her brother undressed on the stairs. She looked quickly to see if they could be seen and turned back in time to see Billy grasp his hard cock and stroke it as slowly went up the stairs. The young girl could not keep her thoughts from her naked brother as he went up the stairs. She tried to tend to the little chores around the shop, straightening this and adjusting that. No one came in and there seemed to be little traffic on the street. She found a simple frame with which to repair the picture. This only made her visualize the photograph of her happy naked parents smiling as they fucked with another woman joining them. Betty thought of her mother touching the other woman as they kissed. She had already had thoughts of holding her father's hard cock, what would it be like to put her hand on her mother's cunt. Would her mother have touched her as well? She suddenly had a vivid picture of herself in her mother's place. Father was fucking her as she put her fingers into mother's cunt. Betty gasped in surprise at the sound of the door. She had somehow sat on the stool behind the counter and had her hand under her dress pushing two fingers into her wet pussy. She quickly jumped up as Miss Primm the schoolteacher came in. They exchanged friendly greetings and Betty served the woman putting her purchase in a wrap of thin paper for her to put in her handbag. Miss Primm wished Betty a good day with an odd look but left without further comment. Betty watched her teacher walk away with her hand over her mouth to stifle the giggles she couldn't stop. What would Miss Primm have thought if she had found her with her fingers in her pussy? What would have happened if Billy had still been on the stairs naked? Flights of fantasy played out in Betty's young mind. She would wait upon Miss Primm naked and her brother Billy would raise the woman's dress and show her cunt and then her naked brother would fuck the teacher as Betty touched her breasts, and they would all share tongues in kisses. Suddenly it was not Miss Primm but mother with Billy and she was naked as Billy fucked her and Betty kissed her breasts. It was surely late enough to close the store for lunch so Betty locked the door and put the sign in the window and went up stairs. She found Billy freshly bathed asleep on father's bed. He was still naked. Betty looked down at her brother as he slept quietly his smooth young body sprawled over the bed covers. His cock was soft but no less lovely to her. She lifted off her dress and carefully sat beside him. Her thoughts were still of the visions she had conjured of them all together. Some emotion made her lean down and lightly kiss Billy's lips and his cheek. He barely stirred. She gently took his soft cock lifting it up and kissed its smooth head. Remembering the taste of his cream on her lips the first time she had frigged him, Betty slowly put out her tongue and licked the smoothness around the little hole. Billy moaned as she did it again and she felt his cock begin to grow. She held his cock as it once again became hard and hot in her hand. Slowly, she frigged it, stroking its length. A small bead of clear oil formed at the opening and Betty licked it away. Relishing the taste the sister kept squeezing a drop out and licking it away. With a sudden jerk Billy came awake just in time to see his naked sister licking his cock. Betty was embarrassed at being caught licking her brother's cock. She quickly scrambled up over him and covered his mouth with hers. She laughed to herself that she was again giving her brother a taste of himself as she pushed her tongue into his mouth. Billy's cock seemed to have a mind of its own and had found its way to his sister's pussy as she spread over him. He reached between them and guided it into her. Betty began to bounce and ride on her brother's cock enjoying the control she had over her own pleasure. Her aroused thoughts made her quickly give down her nectar to coat her brother's cock. Billy then rolled over onto his sister began to fuck for himself until he filled her running puss with his own cream. After the twin brother and sister had rested and dozed for a time, Billy looked lovingly at his sister and kissed her awake. He told her how surprised he was to see her kissing his cock and how very good it felt. Betty laughed and replied that it had been her pleasure. She confessed to his question that she had tasted his cum when he wet her face and that she had stolen tastes as he slept. Betty could not keep to herself that she had purposefully put his own fluid on his lips and put her tongue in his mouth with the taste of his cock. They laughed and shared childish teases Billy tickling and pinching his naked sister until she made him stop. She told him that she another funny thing to tell him about. She then related her daydream about Miss Primm. She tried to describe in detail how they would be naked in the store and how they would strip the teacher of her clothes and how she would put Billy's hard cock in the woman's cunt. She laughed as she told Billy of imagining playing with the woman's breasts as they fucked her. As Betty told of her plan she stroked Billy's hard dripping cock. The exciting fantasy seemed to make her brother's cock even harder and her hand was soon soaked with his clear oil. When Betty fantasized having Miss Primm lick Billy's cock as she had done, Billy begged to see her lick him again. Betty looked into her brother's eyes as she turned her body around and slowly held his hard member up as she licked the flowing juices from it. She giggled as Billy moaned and shivered and tried to pump his cock up to her lips. Billy watched his naked sister squeeze drops from his cock and then lick them away. Then she pulled more up his shaft and carefully gathered it on her tongue and brought it to his mouth. They exchanged tongues and sucked the juices away in a long kiss. When Betty returned to her former position with her mouth over his cock, her young smooth pussy was beside Billy's face. His first thought upon seeing his sister's little cunt that first time was how it was so kissable. Billy opened Betty's legs wide and kissed her puss. She gasped and shuddered all over. Holding her brother's cock tightly she looked down as he put his finger into her wet folds. He brought his wet finger to his waiting tongue and gently tasted. Billy laughed then and put his finger completely in his mouth as his sister watched wide eyed. In keeping with their new experiments, Billy returned his finger to Betty's nectar wet pussy and gathered as much as he could and held his finger down to her. Betty looked at her brother's finger and at his laughing eyes. She worked her courage up and as she opened her mouth to lick Billy pushed his finger into her mouth. She was tricked but the taste was sweet and pleasant so she sucked his finger like a baby. Billy laughed and removed his well sucked finger putting it back in the well of his sister's essence. Betty was now inspired. She spread her legs to their widest and moved her flowing puss to her brother's face. Then as if by example she opened her mouth and slowly lowered it down over her brother's cock. She nursed it as if it were a mother cow's tit. She sucked hard long strokes drawing streams of fluid into her mouth. Swallowing, she would suck again. Betty felt her brother's lips on her cunt but no sooner had his tongue began to push in than her mouth was full of Billy's erupting charge of hot cream. Billy gasped into his sister's pussy as he felt the incredible suction on his cock. Her mouth felt even hotter and wetter than her cunt, the tightness squeezing everything in him out through his cock. She was draining him. Betty sucked and swallowed but her mouth would fill again and again. Billy's sweet cream was a drug that sent her own body into racking passionate convulsions, waves of pleasure washed over her hot and cold together. When the two young lovers awoke it was dark. Betty lay with her head on her brother's leg. Her own leg was thrown over Billy's chest. She looked at her brother's limp cock and rolled her tongue around in her mouth still tasting his cream. With a sudden start Betty realized the time. The entire afternoon had gone by and they had not opened the shop. She carefully lifted herself off Billy without waking him. Starting to look for a dress she realized that she needn't bother. It was dark. No one would see her. Quietly the naked young girl went down stairs to the shop. It felt strange and exciting to be in the place where everyone in town had been. She crept to the front door and removed the lunch sign and substituted the closed sign. Just as she was turning away a couple walked by. She hid at the side of the door afraid to move or to run to the back. The couple talked quietly as they passed and didn't even look at the store. The thought came to Betty's newly aroused since of sexuality that the couple might be going home to fuck. She could see in her minds eye the man's hard cock plunging in and out of the woman's cunt. Tremors came over her slim young body as she imagined the woman taking the cock in her mouth and filling it with cream. Her own fingers found their way to her wet pussy as she felt the man's tongue on her. It felt as if she were about to cum when the stairway door opened and Billy called down for her. Billy stepped down the stairs and called his sister's name quietly. Then he heard a low moan and saw Betty leaning against the front door. She was still naked and seemed to be playing with her puss. He went down to her careful to keep an eye out the windows for anyone looking in. Betty rushed into his arms and covered his mouth with hers as she crushed her body against him. He could feel her tremble as he held her. She calmed then and told him of the couple walking past who could have seen her naked if they had only looked. They laughed in relief but soon were challenging each other to bolder displays. How long would each stand before the big store window naked? Would Billy frig his cock in front? Betty knelt before her brother and put his hard dripping cock in her mouth in full view of anyone passing by the store window. Then Betty had an idea. She reminded Billy of the naughty things they had told about Miss Primm and she told him of the things she had imagined about the couple being in the store naked and fucking and especially about the man's tongue in her pussy. Betty jumped up to sit on the counter top and leaned back opening her slim legs wide. She begged he brother to tongue her pussy. Would he suck her as she had sucked him? Billy fell in with the game and covered his sister's bare pussy with his mouth. He licked open the warm lips and delved inside. He felt the hard little knot there and teased it with his tongue. Betty felt her brother's tongue pushing into the opening of her pussy and he began to fuck her with it. He would fuck and then suck the juices flowing from her and lick as much away from her pink lips as he could. Then start again. It took only moments for Betty to start trembling and her hips would raise to meet her brother's tongue. She was burning all over and her little nipples were so hard that they hurt. She fell back on the counter and took a tiny tit in each hand and tried to squeeze the tingle away but it only made it worse. Again her mind turned to the ordinariness of the store and doing very unordinary things in it. She imagined father naked there holding his cock as he put his tongue in her little pussy. Suddenly she felt her entire body convulse and it seemed to melt and run out of her burning pussy into her brother's sucking mouth. Billy sucked until his sister quit moving, having swallowed mouthfuls of sweetness. He kissed her wet pussy and thighs up her stomach to her open lax mouth. When she failed to respond to his tongue in her mouth he was afraid he had killed her. But he could see that she still breathed. He looked out the windows and saw that they had no audience and gathered his limp sister in his arms and carried her up the stairs. Later that evening as the twins cuddled on their father's bed, Billy asked "Sis, you know those pictures you found, don't you think mother was beautiful? I think she was. I really liked seeing her naked. I wish I could fuck her." "Billy! What a thing to say about mummy!" Betty cried."She's our Mum and we love her." "Oh, I know, but I keep thinking about it. Besides, you're my sister and I have fucked you and I love you too." He replied as he played with one hard pink nipple. "You do?" she asked, "I love you. I guess I think about Father like that too. I wonder what it would be like to touch his cock. I wonder if he would let me... I would let him fuck me if he wanted and Mother could touch me like that other woman in the pictures." "Sis, do you think there are more pictures here?" Billy asked suddenly. Betty was hesitant to look as she still felt a little guilty for having found the first, but at her brother's suggestion that they may find out more about their mother she gave in. In a few minutes Betty found a packet of letters beneath clothing in the bottom of father's chest of drawers. Billy sat beside his sister on the bed as she untied the ribbon holding the letters together. They soon discovered that the letters were not from their mother but the woman with whom their father had been corresponding. Betty lost all guilt now as she opened the envelopes to find out about this person who had stollen her father. The woman's name was Victoria and she lived in a village not too far away. She had even visited father in the store, evidently when the twins were at school for neither could remember having met her. They had only begun to read the first of the letters when a small photograph fell from between the pages. Billy quickly retrieved it from the floor and gasping showed it to his sister. The woman in the picture was naked just mother had been. Billy was the first to note that she was even sitting in the same seat as their mother in the first photographs. When they compared it was indeed clear that this was a picture from the same sitting. Now Billy was inspired to quickly open all of the letters. The brother and sister soon had several pictures. These were not from the same sitting but were seemingly from more recent years. The same woman, older, was in all of the photgraphs and she was also pictured with others. To Billy's delight and Betty's consternation the woman was always naked. They were shown Victoria as she lay on a settee naked with her legs open to show her woman's bare cunt. When she was pictured with others all were naked as well. This one had Victoria seated on a man's lap with her legs to either side facing the camera. They could clearly see the man's hard cock buried in her open cunt as he reached around her to hold her full breasts. In the next the couple were joined by two very young naked children. Each child had a breast to suck and the woman had a hand to each of the children's crotch. The pictures were spread out on the bed. The twins studied them carefully and were aroused by the scenes shown. The woman Victoria was shown being fucked, fondling a naked little boy and girl and being touched in return, and two complicated combinations which involved her being fucked by the same man as she apparently sucked a woman's cunt as the woman played with the same two children's little cock and pussy. Then Victoria was being sucked by the woman as she lay back and had the little boy's cock in her mouth. The man sat on the floor in front of them while the little girl held his cock in her mouth. Betty went through the letters and discovered that the others in the pictures were Victoria's brother and his wife and children. Betty couldn't understand her mixed up feelings. She hated this woman for taking her father away but this same woman must love her brother the same way that Betty loved Billy. She could not deny the way that looking at these pictures of her mother and father naked and making love made her feel. At the same time it was a different feeling that she got from the pictures of Victoria naked with the other naked people, every one touching and loving each other. She could see in the smiling faces that this family loved each other and loved loving each other, even the young children. Would her father be there now, with this woman? Were they naked and were they with the other family? Was her faher being sucked by that little girl instead of her? Betty turned to her brother with tears in her eyes and a tremendous weight of emotion caused her to push him back and fall on him. She smothered him with kisses, licking her tears from his face and down to his hard cock. She sucked his dripping cock into her mouth with such stength that his full balls must have tightened up then quickly mounted over him and stuffed her little puss with her brother's hot cock. Billy hardly knew what to think with this sudden attack but willingly gave his tongue as his naked sister sucked it from his mouth. That night was much like the first night they had made love. Betty would wake and suck Billy hard and they would fuck until they passed out. Betty would awake to find Billy's mouth emptying her pussy and then he would fill it again with tongue and hard cock. The bright light of midmorning was shining around the pulled curtains when the bedroom door opened. Betty roused from sleep and lifted her head from Billy's bare chest. Her hand held his flaccid cock and balls. She looked up at the noise barely able to open her eyes. The bedroom door stood open and Father and a strange woman were standing there looking down at his naked children on his bed. Part 2
