Sister Turned Mistress by: Mr. Ed "Look! The bottom line is you just can't come to our swimming hole with us, Susan," declared Bruce. "You have the nice swimming pool to get into, but our place is not for you." "That doesn't make any sense to me," she declared. "You guys can swim in the pool anytime you want, so I should be allowed to go swimming in a river you don't own. It's not your property, so how can you keep me away?" There seemed little choice but to explain why to Susan, and hope that would be enough to put an end to the argument. "You might as well tell her, Bruce," offered Gordon, with this supported by murmurs from the other guys. "Getting to the swimming hole is really hard, Susan. It means climbing, going through some rough bushes, and just doesn't seem to make any sense for a girl to go there, if you were able to get through," offered Bruce in his last effort to discourage her. "You know I can handle rough stuff like that, and I want to spend time with you guys!" countered Susan. "We don't wear anything when we are swimming, Susan!" declared Bruce finally. "We go in naked, and sometimes guys get excited. Girls just don't fit into the picture!" "So that's it!" she declared at last, as if a light bulb had come on in her head. "Now I understand!" Bruce finally felt he had won the argument, and the guys were collecting their towels and preparing to leave. There were about ten or eleven guys, apart from himself, that would be at the swimming hole at any one time, depending on who had other things to do that particular day. All of them were between nine and twelve years old, and represented the guys from the entire district in which they lived. Bruce happened to be one of the older at nearly thirteen years old, so he was looked to as one of their leaders. He didn't feel like he was a leader; just that the younger seemed willing to follow his example, and they usually were able to have fun. Heading out from his yard, they headed towards the river, and the climb necessary to get to their favourite place to swim, and where they could let a guy be a guy if he felt like it. More than one had gone off to masturbate in the surrounding bushes, usually with one or two other guys encouraging him on, and to witness how far his seed would shoot out. It had almost become an every time event for at least one guy to do it, although Bruce had not yet done that himself. He had witnessed a couple of the older guys doing it, and knew he would have to some time soon. The climb, as always, was not easy, and they knew that was good. No one else came near the almost perfect swimming hole at the river bend because it was hard to get to. They all got through, stripped naked, were in the water in short time and the horse play began. Half an hour later, Bruce became the one to masturbate today, with the other guys all kneading him into it. Going to the traditional place, he began to pump his penis, closing his eyes to think about Susan stripped naked. She was the best looking girl in the district, and the one he would think about when he did it himself alone in his bed. It was his best chance to use her as his 'object of desire' now, thereby bringing him to a climax easily. As he pumped, he was thinking about how he had witnessed her getting a spanking one day. Her mother had pulled her over her knee, dropped her shorts and panties, and gave it to her good. He had been there but had been forgotten in the heat of the moment, allowing him to see the bare ass of her then nine year old bum, and a little of her crotch down below. By imagining his moving to a better vantage point, he wondered about the details of her crotch, and came. The cheers for how far he shot his seed out were from all of the guys that had gathered around to watch. At least it was over, he had done it now, so would not have to do it again for some time. Now he could get back to the swimming, and forget the demonstration he had put on. Mind you, the feeling he got doing it in front of the other guys was better than when he was alone. It was kind of sexy having witnesses to his coming and not so bad now that it was done. All too soon the time was getting on, and they had to get back, most of them for supper. After drying off they got dressed again ready to begin the difficult return trip. Splitting up as they reached logical disbursement points, guys headed their own directions. Bruce said goodbye to the last friend at his gate, as the one other had to go further down the road. Susan was wearing a stupid big grin for some reason, but he ignored that, and went about hanging up his towel, and checking what was to eat this evening. Supper was done, it was dark and Bruce was just coming back from having a pee out behind the house. Susan came out the back door, saw him approaching and ran over to him. Without a moments hesitation she pushed her front against him, and kissed him nicer than any other girl had ever kissed him before. He was shocked by the event, but it felt nice to feel her against him, and to have kissed her like that. "This is nice, but why?" asked Bruce, still hugging her lightly. "Because I think you are the most handsome big brother any girl could ever have, and I love you!" she declared as she leaned forward and kissed him again. It was full on his mouth, and this time she made him open his mouth a little as they rubbed their lips together. He had no control over his penis getting hard, but she pushed herself against it, and would not pull away. "You are going to be upset with me, and I will give you a chance to get even, but I love you, and think you are the most handsome guy ever!" she told him. "What did you do, Susan?" he demanded. It had to be something bad, and he felt defensive. "Remember, you're going to get even, so don't get too uptight," she cautioned. "I followed you guys to the river, and saw what you did. You were fantastic!" Bruce started to say something, looked at her, pushed her away and left her standing there. All he wanted to do was go to his room and hide. His kid sister had watched him masturbate while he was naked! By mid morning, Susan was well aware of his anger. He had not said a single word to her, and had no intention of saying anything, no matter what she might say or do. As a matter of fact, he wanted to get out of the yard, and not even have to look upon her. Near the gate he was considering where he would go when she came up behind him. "You can do anything you want to me, Bruce," she said from behind him. "I'm so sorry I did it, and will do anything so you won't be so mad at me!" "If you will do anything, then why don't you leave me alone?" he responded, as he started through the gate. He hadn't decided where to go, but needed to go somewhere. "Please, Bruce?" she called as she dropped to her knees. "Bruce!" called his mother. "I don't know what Susan did to you, but talk to her. Tell her why you are so mad at her. Work it out!" "She's a sneaky cheater, Mom! I can't stand to even see her!" he declared. "And I can see she regrets it, Bruce," replied their mother. "I know, deep down, you still love her. Everyone makes mistakes, and needs to be forgiven! You've made a few mistakes yourself!" "I'm going over to Gordon's for a few minutes, and will think about it, Mom. All my chores are done, and will be back in time for lunch. Okay?" "Think hard about it, Bruce," she concluded. "Go on now!" Bruce jogged down the road, his anger seething, but his Mom's words were ringing in his head. She really wasn't all that bad as a sister, often doing nice things for him. It was just that what she did this time hurt his pride so severely, he didn't want to stop being angry. Realizing this made it a little bit easier to ease the anger, but only a little. Gordon had not even been home when he got there. He had gone into town for his mother, and he had nobody to talk to about it. Then again, if he told Gordon, then he would be angry for she must have seen him naked too! Maybe it was just as well, he decided as he sauntered back home. He was still a little way from the yard when Susan ran towards him. Even his private thinking time was to be robbed of him by his sister! He could see the dried streaks on her cheeks, for she had been crying. Well she deserved to be upset for he was, and with better reason. "Please, Bruce?" she begged as she came close enough to be heard. "I'm so sorry, and you can get even with me anyway you want!" "What you deserve is to be stripped naked and have your bare ass beaten in front of all the guys!" he declared. "Would you talk to me afterwards?" she asked. "Do you understand what I just said?" he demanded. "I'd want to die, but if that's what it would take for you to forgive me, then do it!" she declared. Bruce stopped and looked at her. "I don't get it," he said. "What's so important about me talking to you? You have all your girlfriends, so why don't you go talk to them?" "They're only friends, but I love you, and would do anything for you, Bruce. It hurts so bad when you won't talk to me!" "I don't know what I want to do to you, Susan!" he exclaimed. "For sure I've got to do something. What you did is the worst thing that could ever happen to a guy! Don't you ever say anything about what you saw to anybody...Mom included!" "Oh, no!" she exclaimed. "I'm sorry, Bruce! Mom made me tell her!" "Bruce!" called his Mom from the gate. "Come on home, Son!" "I think I want to kill you right now, Susan!" he declared as he headed towards his gate. He could hear her walking a little way behind, and her crying again. What would he say to his mother now? "Come on, Bruce," she called as they got closer. "We've got hot dogs to roast in the fire. You like them!" "You're still talking to me, Mom?" he asked. "Big mouth told you what she saw, and you still are talking to me?" "Making my big man his favourite lunch too," she pointed out as she put her arm around his shoulders. "Everything will be okay, Bruce, and I will always love you, no matter what you do!" "You're something else, Mom," he stated. "Thanks!" "What you did is part of your natural development, although in front of others is a bit surprising. From what I hear, I have to be proud of your size, but I'm always proud of my boy, turning into a man. Just take it a little easy on Susan. She's really sorry for what she saw!" "Excuse me, Mom," he said as he turned about and walked over to Susan. "I'm still pissed with you, Susan," he said, "but come on. I'm going to get even with you, but you're not so bad to have as a kid sister. Let's go have lunch!" Susan sank down to her knees again in front of him, and said, "I'm really sorry, Bruce, and thank you for talking to me again." "Get up and come on," he said, taking hold of her arm. They joined their mother, and headed for the promised lunch. During lunch, Susan remained glued to him like his shadow. The only exception was when he was about to get another hot dog, and she went for it first. She even knew what he liked to put on it, and did it for him, leaving her own to get cold while she took care of his. "Thanks for this," he said as she handed it to him. "I could have managed it, and yours is getting cold." "I don't care, Bruce," she said taking up hers and sitting back at his side. After she took a bite, she mumbled something he couldn't understand, but let it pass. Mom came over and sat opposite him when he was swallowing the last bite of lunch. "Have you decided what you want to do to Susan for revenge?" she asked. "What she deserves Mom, is to be stripped naked, and have her bare ass beaten in front of all the guys she was spying on. She knew we went swimming naked and deliberately spied on us. Don't worry, though that can't happen for it would mean the other guys would find out she spied on them, and I don't want her to be hurt by them." "I can understand your anger, for your pride has been hurt. If that is what would make you feel better, why don't you do that to her here at home where it is just the two of you?" "You'd let me strip and beat her?" he asked. "She certainly deserves something for she was deliberate about it. Yes, I'd allow you to do that!" "I don't like the idea of the beating, but would live with it, Bruce," said Susan, "just as long as you would talk to me afterwards. I'm really sorry, and I know I shouldn't have followed you like that." "Well, I've got to do something, so finish your lunch and let's get it over with. To be honest, I hate being so angry too! We usually have more fun together than any other time. You should watch though, Mom. I don't want to get carried away and hurt her too much." "Come on, Susan," said their mother. "If Bruce is going to let me be there, then I can at least hold your hand." Something had changed in how his mother was treating him, and Bruce could not identify what or why. All he knew was it was different, and rather nice in some way. He watched Susan's bum as she walked ahead of him to the house beside his mother, knowing he would be seeing it and beating her in a few minutes. Actually, even though he was still so angry, he felt a little sorry for her, knowing how it would hurt. Standing in the living room, Susan was whimpering as she undressed. Mom got out the belt that she had made them feel on some occasions, and handed it to Bruce. Then she went over to her naked daughter, led her towards the chesterfield, and got her to lay down on her belly. All during that time she held Susan's hand, taking hold with both of hers as she sat down on the floor beside her. Susan was still whimpering as he went over to stand beside the chesterfield. Bruce brought the belt down across her bare bum three times in quick succession, using up the anger he felt inside. As he was about to bring down the fourth, he looked at her red bum, and heard her crying so deeply. Lowering the belt, he threw it across the room, and knelt down beside Susan's shoulders, near where their Mom was. "Are you okay, Susan?" he asked. "I know you deserved it, but now I'm sorry I did it to you!" "Will you forgive me now, Bruce?" she asked when she turned her face to him. "Yea," he agreed. "I suppose we are even now. By the way, you sure are pretty now that you have breasts. I'm glad I got to see them and all of you!" "Oh, Bruce!" she exhaled as she got up. She came down to sit on his lap on the floor, and wrapped her arms around his neck before kissing his lips. "I love you, and even if you want to give me another, I'm glad I saw what you did. I'm so proud to be your kid sister!" "I love you too, Sis," he replied. "Is your bum okay now?" "Burns like pepper," she told him. "Don't make me feel guilty, because I'm not going to kiss it better," he stated emphatically. "To bad," she said. "It would help if you did!" "You'd better get dressed again soon," he said. "I can't handle looking at such a pretty girl." "I can tell since I feel it," she said, glancing down to her lap. "Would you put up with another kiss like before?" "I just beat your bum and you're talking to me like I was your very best friend in the world!" he exclaimed. "You're weird!" "Well you are, and I don't care if that makes me weird." Leaning forward the kiss was opened mouthed, long and passionate, but very, very stimulating as his penis jumped against his pants, and her leg. "Get dressed before Mom needs to give me a beating, Susan," he said. "Why would I want to beat you, Son?" asked his mother. "Because of what I'm thinking about my sister," he admitted. "Please understand it really is very sexy to see her like this, now that she looks so sweet." "Stay where you are, Susan," instructed their mother. "I think I have something I should tell you both. The time has come it seems." "Now you have my attention, Mom," said Bruce. "This sounds serious!" "In one way it is," she agreed, "but in others, it's not. You see, you were too young to remember, but Susan is not your sister. She was brought to me when she was less than a year old, and her real mother is overseas. I've been bringing her up since she was a baby. You're still my baby, Susan. Don't worry about that, for you always will be!" "I've got two Mommies?" she asked, holding onto Bruce tighter than before. "I'll always be your 'Mommy' Susan," she replied. "You do have another though. She was my best friend when we were young, and decided to leave you with me when you were just a little baby. Ever since she went abroad, she's been sending me money and hearing about you. She will come back one day, and want to see her little daughter. I think she will be so pleased at how nice you turned out!" "Oh, shit! That means...Oh, Lord, I'm sorry Mommy, I didn't mean to swear like that!" "It's okay, Susan. What does it mean to you?" "That means Bruce is not my brother!" "You don't want to be my sister?" he asked. "Not when it means I can't have sex with you!" she declared. "What?" demanded Bruce. "Susan knows she is not related directly with you, Bruce," said their mother. "She knows she shouldn't make love to her brother, but you are not her brother!" "So you are going to let us have sex together?" he asked, not believing what he was hearing. "I knew it would happen one day. Susan loves you better than anyone else, Bruce, and I know you love her too. Yes, I'm going to let you two have sex together, do what is necessary to keep Susan from getting a baby too soon. I had you too early in my life, Son, but you may enjoy her as a woman. You are both ready to experience the joy of sex." Bruce and Susan stared at each other, each taking a turn glancing at their mother, and then looked back at each other. Both their minds were reeling from the new understanding they had, and trying to grasp the implications for their future. Reaching up, Bruce stroked Susan's face, and as his gaze went down to look at her nudity, she pulled back enough for him to see clearly. As his gaze returned to her face, she pulled back close to him, and rested her head on his forehead. "Wow!" she exclaimed. "Wow for true!" he responded. "You're not kidding are you, Mom?" he asked turning to her. "No, my beautiful baby boy! I'm not kidding!" "Do you have to call me that, Mom?" he asked with a smile. "I'm not thinking like a baby now!" "You're thinking like a man, and I'm as jealous as hell!" she replied. "I'm pretty certain that Susan is interested right now, you have the time necessary, and I'm here to be able to help Susan when she needs the help." "You feel like making love to me, Susan?" asked Bruce. "I'm ready to become a woman...your woman whenever you want me, Bruce," she replied. "Maybe I should kiss your ass better," he suggested as a joke. "I'd love if you did, Bruce," she responded seriously. "Any place you want to kiss!" "Care to give me that talk now, Mom?" he asked. "I know I want to do things with Susan, but don't know much about doing them." "Slap my hand for me, Bruce," instructed his mother as she held it palm up towards him. "What is this for?" he asked as he put his hand into hers. "For being too shy to have told you already," she said, holding his hand nicely. I'm not so experienced as a mother as I should be." "But I think you are the greatest, Mom!" he exclaimed. "Me too," supported Susan. "You'll always be my Mom to me, Mom!" "Okay then you know what the breasts are for, don't you Bruce. Wait, I shouldn't presume that. The breasts are grown so that a woman can feed a child after it is born. They change and get bigger while a woman is pregnant, called lactating, and when the baby is born, then she can get milk from them, just as both of you got milk from me." "You had me to your breasts, Mom?" asked Susan. "Yes," she confirmed. "I was already prepared since I was still feeding Bruce, so when you came along; you were all too ready to suck on them. Some of my best memories are from feeding you two. Now, when a mother is not feeding a baby, the breasts are still a very sensitive organ, and touching them, especially at the nipples will arouse any woman. To have them held, caressed, or kissed is a wonderful experience for any sensual woman." "You mean like this?" asked Bruce as he placed his hand on Susan's breast. "Oh, yes, like that," confirmed Susan as she put her head back. "Play with it for me, Bruce! It feels so good!" "I've wanted to do this since I first saw that they were growing on your chest, Susan," he told her. "They could have been yours any time you wanted them Bruce," she declared, "even when I didn't know it was alright to let you." "I've seen that you have already discovered how sensitive your lips are, and are doing fine in learning about that. You might want to use your tongues sometime to make it even better. More important, though is the girl's crotch and what is there, and how it works. Are you going to let me teach Bruce using you, Susan?" "For sure, Mom," she declared. "Oh, I'm going to like this part." "Sit up on the chesterfield, darling," instructed their mother. "Something tells me you won't be the only one to like this part, Susan," declared Bruce. "Look at you, so sexy!" "This entire area is known as the groin, or crotch, and anyplace down here is sensitive to the touch, some places more than others. These two folds of skin, here and here, are the vulva lips. They have a more proper name, but that's what I call them. Now, when you spread them apart, you can see this fold of skin coming down the middle. It's the clitoris, sometimes called the clit. As you can see, it is very sensitive to touch, and Susan would really enjoy having it played with. Down here at the bottom is where her urine comes out. I think you can see her little hole up there, can't you?" "I can see everything down there, Mom," he said. "Actually I feel like I'm seeing something I shouldn't see." "It's okay, Bruce," exclaimed Susan. "I don't mind you seeing me down there or anywhere! Having you look, and when Mommy touches me, makes it feel wonderful!" "Down here you see her anus, which I'm sure you call her asshole," said Mom. "It is possible to insert your penis in there to have sex, but it is much tighter, and unless she is very excited, it would be very tight to go in. Some girls like it up there, but not all." "Moving back to the most important place to any man is her vaginal opening. This is where your penis will go in. Now see inside here? This piece of skin, right here, is call the hymen, or the cherry. To have sex in a girl means it must be broken, and will hurt the girl when it breaks. When it is broken, the opening goes much deeper, and way up inside is her cervix and inside there is her womb. It's in the womb where a baby grows for about nine months, and them is born through this same opening." "Is that on opening under the hymen?" asked Bruce. "Yes, and that is how a girl on her menstrual period can insert a tampon. You've seen the ones I use, and asked me about them one day, Bruce." "In the little cardboard tubes?" he asked. "That's the one," she confirmed. "No wonder you wouldn't let me play with it, Mom," he said. "I'm sorry!" "You were curious, and thought it was a toy," she replied. "That's nothing to be sorry about." "But if that could go in a girl before sex, then a finger could also fit up in there," he observed. "Yes, it can, and that's what Susan, and every other virgin girl does to herself, just like when you pumped your penis to make you excited." "Girls feel the same thing a guy does?" he asked. "It's a little different, but she sure does," confirmed their mother. "My legs are getting really tired, Mom," reported Susan. "May I put them down for a few minutes?" "You should be able to hold them up longer than that, Susan," she advised. "Yes darling, set them down for a little." "Why do I need to hold them up longer, Mommy?" asked Susan when she was sitting up. "You want your man to be inside you as long as possible, so you need to hold them up to get him in the deepest he can go and the longest he can stay." "Any chance I could feel what it's like to put a finger up inside?" asked Bruce. "Oh, would you, Bruce?" asked Susan. "Susan is willing, so go ahead, Son," suggested his mother. As Bruce went back up onto his knees, Susan lay back once again; her legs raised high in the air. Bruce looked, leaned over and placed a kiss on her vulva lips, to the surprise of both Susan and their mother. Then he brought his finger up to the opening. Using his other hand, he spread the opening somewhat, saw where he was thinking of, and pushed his finger down under her cherry, going on in as deep as he could get. Susan was moaning, but somehow Bruce knew it was not from pain, but pleasure. "Okay, Susan, thanks. I'm going to pull it out now," he told her. "Please, Bruce, not yet!" she begged. "Keep it in there just a little longer. I'm going to come any moment." Bruce somehow knew, so he pulled it back almost out, and then pressed it back up inside. Susan immediately began moaning and pounding the chesterfield with her little fists. Her opening became even more open, and he knew she was feeling the equivalent of when he came and shot out his semen. The only difference was she was getting wetter in her vagina, instead of squirting all over the place like he would. "You gave Susan a climax, Bruce," offered their mother. "Just like she witnessed in me," he said. Leaning down, he kissed both of the cheeks of her bum, for he had beaten it for watching him come, but she didn't deserve it. "Why did you kiss her butt?" asked Mom. "To make it feel better since I beat her a few minutes ago!" he replied. "Susan is a very lucky girl to have a young man like you, Son," commented Mom. "I'm the lucky one, sitting here with a finger up in her cunt," he declared. "Is it alright to call it that, Mom?" "When you are sharing intimate moments like this, then you sometimes use those terms," she told him. Just not outside of those times, though." "As soon as Susan is ready, I'm going to need to go and masturbate, Mom. Doing this, it's just so damn sexy, I have to!" "Susan might want to help you, Bruce," suggested Mom. "May I, please, Bruce? You could come in my mouth, ass or cunt if you wanted," offered Susan. "Are you going to let me, Mom?" asked Bruce. "If you will do it right here, I'd be grateful," she replied. "I'd love to see you love your sister, and have your first sex in her." As she was speaking, she started to undo his shirt. Bruce pulled out of Susan, stood up and started undoing his pants as his Mom removed his shirt. Moments later, he was naked, had guided Susan to turn length ways on the chesterfield, and was climbing over her. Mom took hold of his penis, changed where it was pointing a little, and as he kissed the lips of Susan, he pressed down inside her a little, feeling the barrier. "I guess this is going to be the hurt time, Susan," he warned her. "It can't be worse than the beating, Bruce," she said. "Do it!" With a sustained push, he was suddenly free, and deep inside her, resting his belly against hers. "That did hurt a little," she reported, her head turned away. "You're a woman now, Susan," reported their mother. "Want me to come out?" asked Bruce. "No!" exclaimed Susan. "Please, no!" "I was going to kiss it better for you," he said. "Do that later," she suggested. "Just fuck me now, please Bruce. I want to feel you inside me, just like it is right now." Bruce began to pull out slowly, returning inside just a little faster than he pulled back. He heard her moan and cry out with the satisfaction she felt. Feeling at liberty, he did the next pull and push a little faster, getting the same moan of satisfaction. Slowly he built up his speed, until he could go no faster. "It's so good, Mommy!" exclaimed Susan. "I know, baby," she replied. "You're so lucky to have a young man like Bruce! I'm jealous!" "I'm going to come!" she exclaimed. "Let it go, Susan! I'm coming too!" exclaimed Bruce. Suddenly, all his muscle control was gone, and his weight was down on Susan. Try as he might, he could not get back up, and quit trying when she wrapped him tight with her arms. Nothing before, including in his imagination, matched up with what he felt at that moment. Some two to three minutes later, his effort to keep it inside his girl were abandoned, and it slipped out, soft and limp. He had spent the time from finishing his climax until then telling Susan how wonderful she and the act were, and how he wanted to share many such times with her again. Now the two sat up, close to each other, and shared a couple of kisses. "Come on, Susan," instructed their mother. "It's time to fix you up so you will be able to do this again as often as the mood takes you." "May I come with you, Mom?" asked Bruce. "I don't want Susan to leave me right now." "Yes, Bruce," she replied. "Come and see what a girl has to go through for her man." Bruce got to witness the douche that Susan got, and then the insertion of an I U D into her so she would not get pregnant. He had a hard time understanding how it might work, and ended up leaving it as something to accept, rather then something to understand. From that night forward, they shared the same bed, and a lot of sex. There was never any hesitation to perform the act where the mood took them, and Mom was a frequent witness to the event. After they had made love on the living room floor in front of her, Bruce came to realize the extent of his mother's frustration at watching and not having her own man. Sometime a little later, he made love to his mother, finally relieving her frustrations. After that, it became three way sex, with either or both the ladies receiving his penis inside one of their three orifices very regularly.
