Date: Fri, 5 Jan 2018 11:03:31 +0000 (UTC) From: Tony Williams Subject: My Slutty Sisters My Slutty Sisters By Tony Williams I'd just been released from the Youth Custody Centre, having served six month of a year long sentence for car theft. Shit, it was so good to get out! Mum picked me up and brought me home. I'd thought that I'd be regularly raped in there, but as it happened, it only occurred once. An older boy tried to fuck me while two others held me down, but I clenched my arse and he couldn't get it in and so he gave up. Lots of boys wanted to fondle my cock and wank and suck me off, and I was happy to accommodate the better looking younger ones. Don't tell anyone but I even sucked a few dicks myself. I kinda got to like it, but I missed the company of girls, especially my sisters. I was twelve years old. My old room was just the same, my stuff untouched as though it was waiting for me. Mum was downstairs watching daytime TV when my big sister came home from school. She's a year older than me. "Tony's up in his room, Nancy," I heard Mum say, then the sound of feet dashing up the stairs, and Nancy flung the door open. She stood there, a huge welcoming grin on her face. "You're back! It's SO good to see you!" I held my arms wide and she stepped into them. We hugged and then I stepped back and looked at her. "You've grown," I observed. "You're taller." She kicked the door shut behind her. "And I've got tits," she said proudly, smoothing the front of her dress over her chest. Sure enough, two little bumps nestled under the blue flowered cotton. "Wanna see?" She lifted the hem of her dress as high as it would go, bunching it under her chin. Her knickers were pale pink with white trim. I could see the hint of a camel toe and I could feel my cock getting stiff. She was right about her tits: two distinct swelling were topped by surprisingly big pink nipples. "Like `em?" "Awesome!" My God, she was growing up. The last time I saw her she was just a little girl with a flat chest, not sexy at all, unless you like little girls. "You can touch them if you like," she said. I reached out with both hands and placed my palms on them, gently rubbing her nipples, then I tweaked them with my fingers, gently pinching them. They became almost instantly hard, so I leaned in and kissed them, first left then right. I stood back, running my gaze up and down her body. Her hips had broadened. "Wanna see my cunt, too?" Oh, I love it when girls talk dirty. Without waiting for an answer, she trapped her dress under her chin and pulled her knickers down to mid thigh. Her cunt had changed too. Instead of just a vertical slit, she now had cute little lips and an arch over her tiny clit, and above it a faint trace of dark hair. I knew from all the porn I'd seen that it would change some more as she got older. "Go on, touch it. I don't mind." My hand pressed against her mound, then slid down, my middle finger pressing flat between her lips, then I curled it and it slid into her. Her smiled widened. "I like a finger fuck," she murmured. "So who finger fucks you? A boyfriend?" "I don't have a boyfriend, no. Girls at school. We finger each other. Don't you guys wank each other off when there are no girls available?" She'd hit the nail on the head. I gave her a guilty grin. She stepped back, and pushed me so that I sat on my bed, then she dropped to her knees, unfastened my pants and pulled them down. Her dress remained jammed up across her chest. "Ugh! Ugly boxers!" "They're what they issue in the nick. I'm gonna go back to my ordinary briefs." "Then let's get rid of these." I lifted my hips so she could drag them down to my ankles and kick them off. My cock sprang out, now fully hard and wet at the end. She took hold of it. "It's grown since I last saw it. I can give you a better wank than any boy," she said, stroking it slowly up and down. She was right, I'd never been so turned on in my life. "Now I'm gonna suck it," she declared, not giving me a chance to stop her. As if I would! She leaned in and puts her lips round the end of my cock. They were warmer and softer than any bloke in the nick and I knew I couldn't last very longer before I came. I'd never even kissed a girl before and for the last six months, I hadn't even seen one, and now a girl was sucking my cock, even if she was my sister, and it was out of this world. I held out for about half a minute and I could feel my orgasm building. I was right on the edge. That's when the bedroom door slammed open and in stepped my younger sister, Twiggy. "FUCK!" I yelled, pushing Nancy off me and covering my throbbing cock with my hands. "Don't you ever knock?" Her eyes were huge as she stared at both of us, our clothing in disarray. "Oh, my God, Nance, you were sucking him off!" "DON'T TELL MUM!" Nancy cried, glaring at her sister. "I just wanted to welcome Tony home," Twiggy said, apologetically. Then a sly look crossed her face. "Oh, Nance, you naughty girl! Sucking your own brother off! Oh, this is precious!" "You better not tell anyone or I'll . . ." "You'll what?" I interjected. "I'll take your knickers down and spank your bum hard." "Ooooh, Tony's gonna take my knickers down," she said, grinning. "Did you pull Nancy's down?" "No, I pulled them down myself," Nancy answered, pulling them back up again, and letting her dress fall. "But I won't hesitate to pull yours down and thrash you if you tell." "Don't bother," Twiggy said, lifting her own dress and tugging at her white knickers, letting them fall to her ankles. "I don't mind if Tony looks at my muffin." That's her pet name for her cunt, charming and innocent. Mum nicknamed her "Twiggy" because not only is she as thin as a twig, but there was an ultra slender teenaged model of that name, many years ago, even before Mum's time, the first of the English skinny supermodels and Mum thinks she'll grow up to be just as famous. She's only eleven. Dream on, Mum. "He can look at me all over if he likes." She lifted her dress over her head and tossed it aside, standing with her feet parted and her arms spread wide, her pose crying out, "Look at me!" "Hey, you're growing up, too," I said, not because her body had changed since I went away, but to boost her self esteem, not that it seemed to need much boosting. "Am I sexy?" she asked. Nancy snorted. I eye her up and down. "Yes," I said. "In your own way, you're sexy. If you like little girls, that is." "Don't you like little girls then?" Until then I'd never thought about twiggy in that way, but now, as she deliberately displayed her naked body for my benefit, I could feel and unfamiliar urge stirring in my abdomen. It wasn't the sight of her naked body, it was the way she was deliberately showing it off, like an invitation. "Yes, Twiggy, but only in your case. You're very pretty and, well, being naked like that, I think . . . tell you what, give me a hug to welcome me home." I stood and she put her arms round me, pulling her body against mine. I have to confess that my cock had not entirely lost its stiffness and as she was almost a foot shorter than I, it pressed against her chest. She leaned back and looked down at it, then up into my eyes. "Can I suck it, too?" This was completely beyond the bounds of normal behavior, but the look on her face was like a puppy being offered a juicy treat, eagerly pleading, and I just couldn't say no. But Nancy could. "You're too young," she said, firmly. "And anyway, you'll just tell all your friends." "If you do tell," I say, "it'll be all over the school and the neighbourhood in hours and I'll go back to the nick, this time for years, probably until I'm eighteen." "I'll never, never, never tell," she said. "I don't want to lose you again." She'd never expressed her affection for me in that way before and my heart swelled. I looked at Nancy who now seemed like a mature woman by comparison. I lifted my eyebrows. "You fucking pervert," she said, but I could detect a hidden smile in her voice. "Sticking your cock in the mouths of little girls. You should be ashamed of yourself." "You're not so big!" Twiggy said. "Yeah," I agreed. "You're a fine one to talk. You're only thirteen." "Juliette was only thirteen. You know, Shakespeare? I bet she sucked Romeo's cock." "It was different back in those days. They married their kids off early." "Did they suck cocks though?" Twiggy asked. I had to laugh. "If they didn't then I'm glad we're in the twenty first century. I think they must have." "Then I'm gonna suck cocks when I'm thirteen, but meanwhile, I think I should practice." "Oh, my God!" Nancy whispered to herself. "She's actually gonna suck him!" Twiggy sat on the end of the bed and put her hands on my hips, pulling me towards her. Her tongue poked out and tentatively touched the end of my cock. It felt like an electric shock. She opened her mouth as wide as she could and put her lips round the head. I felt her tongue tickling it. More electricity. She could only get about half of its length in her mouth. Her hand gripped my shaft and slowly stroked it. I was so aroused by Nancy's earlier administrations and by our conversation that once again I knew I was about to shoot my load. ""I'm gonna cum!" I cried, trying to warn Twiggy, but she kept her mouth on me. "Here it cums! Watch out!" My first pulse shot right into her mouth and she instantly pulled her head back, so the second shot landed on her forehead, the third on her cheek and the fourth on her nose, dripping off the end. "Don't stop, just milk it," I demanded and she squeezed the last drop from it. It hung by a thread, threatening to fall to the floor. No problem, I'd cum on that rug dozens of times before I went away and the stains weren't visible. Twiggy looked up at me, laughing. "Wow!" she said. "Did I do that? Awesome!" Then I saw her swallow. "Mmm, it doesn't taste bad at all." "Wipe your face," said Nancy. Twiggy looked round for something to wipe with and found my ugly prison boxers. I had a sudden idea. "Why don't you lick her face clean?" I suggested. "She said it doesn't taste bad, so you should get used to it, in case you wanna suck me off again." "I dare you!" said Twiggy. Nancy hesitated for a beat, then sat beside her sister, put her hands on her shoulders and licked her face, five, six long licks, swallowing after each one. Then she kissed Twiggy lightly on the lips and leaned away. "You're a bad, bad girl, Twiggy," she said. "You're both bad, bad girls," I say, "and later on this evening, I'm gonna take both your knickers down and spank your bare bums." They smiled. "Will you finger my cunt again?" Nancy asks. "He fingered your cunt?"Twiggy asks incredulously. "Wow!" "I did and yes, I will, if you're nice to me." "Will you finger mine, Tony?" Her big eyes looked up at me, pleading for affection. "Absolutely. You're growing up, too. But now I'm wiped out and you'll both have to wait until I recover. How about bed time? Now get dressed in case Mum comes in." They scrambled into their clothes and left, laughing and giggling. Holy fucking shit, I thought to myself. I'm only a couple of hours out of the knick and I've already committed a crime that can put me back inside. I've had sex with both my sisters, for Christ's sake! I must be a fucking pervert, but then they're both so fucking irresistible. I could see how Nancy was able to seduce me with her new tits and growing pussy complete with pubic hair, but Twiggy was still just a child, prepubescent, a year or more away from puberty and she should've been off limits. On the other hand, she'd come on to me. I hadn't forced her to do anything. Given that she was so willing, what harm could it do? I hadn't wanted to disappoint her. I decided to think of the whole episode as sex education. I found my old white briefs in my dresser draw, put them on and looked at myself in the mirror. That was better. I actually looked pretty hot. No wonder guys in the knick liked to suck me off. I was an eminently suckable hunk. __________________________________ Mum went to bed early, about nine o'clock. "It's not a school day tomorrow, but don't let them stay up too late," she told me, kissing me on the cheek. "It's good to have you home again, Tony." She toddled off, up the stairs. My sisters looked at me, eagerly. "Let's go to my room," I suggested. "Mum always knocks before she comes in which will give you time to hide under my bed or in the closet. We can do anything we like, guys." In my room, they look at me, expectantly. "I want you to undress each other," I announced. "Like lesbians?" said Nancy. "We're not lesbians." "There's nothing wrong with being gay. You can be a bit gay if you want. I just wanna watch you, that's all." "I don't mind," said Twiggy. "I'm not gonna grow up to be gay. I'm gonna be a cocksucker." She smirks. "Take my dress of, Nance." In a flash, it was gone. In her little white cotton knickers, she seemed to look even sexier than earlier in the day. "Did you suck cock in the nick?" Nancy asks. Good question. I might as well come clean. "Yes, I did, and no, no one made me do it. It was just that the guys I sucked were the really fucking sexy ones. Twinks, they're called. And yes, I liked it. I developed a tasted for cum." "You swallowed?" she asked. "Not at first, but after the first few times, yes." "How many boys?" Twiggy asked, her eyes bright with excitement. "Fifteen, twenty, more or less." "You mean total sucks or the number of guys?" Nancy asked. "Different guys, twenty of them." "Wow! I suppose it was because there were no girls available," said Twiggy. "You've got girls available now. You've got us." I was amazed at her promiscuity. "And I intend to take advantage of that fact. Come one, Twiggy, do your thing." She lifted Nancy's dress off, exposing those delicious little titties. In her knickers, she looked just as sexy as her sister. "Take my knickers off, Nance," said Twiggy and I was treated to the delightful sight of my big sister pulling my little sister's knickers down, and then they reversed roles and then they were both naked, letting me stare at them. "He likes my cunt," said Nancy. "Look how he's staring at it!" "And mine. He's staring at my muffin, too." "Call it your `cunt'. You're a big girl now." "You both have sexy cunts," I assure them. "You should get undressed," said Twiggy, "so we can look at your cock." I quickly stripped off and stood, allowing them to gaze at my rapidly stiffening cock. "You've seen it before. You've even sucked it," I pointed out. "But we still like to look at it," said Twiggy. "It's awesome!" It was time to move along. "Can I touch your muffin, Twiggy?" "Why her, why not me?" asked Nancy. "Because I fingered you earlier and now it's her turn." I sat on the bed and Twiggy stepped up to me, her hands on her hips, her pelvis thrust forward. I spun her round, pulled her down on to my lap with her back to my chest, put one hand on her chest, fingering her nipple and put the other hand between her legs, probing with my finger. It went into her with no resistance at all. "Your cherry's broken," I observed. "I did it with Mum's vibrator," "She has a vibrator?" "She hides it in her dresser drawer. I borrowed it. Several times, actually." Wow, I thought, my little sister's more mature than I imagined. "How does this feel?" "Better than the vibrator. It's nice. I do it to myself in bed at night." "Yeah," said Nancy, "I can hear you." "Good girl. All girls should masturbate. All boys do." "Do me, too," said Nancy, stepping close enough for me to reach out and slide my hand between her legs. She was already wet. There I was, each of my middle fingers up the cunts of my dirty-minded sisters. My cock was like an iron bar. "This feels better than when I do it to myself," said Nancy. "Yeah, it does," added Twiggy. "I'm surprised you guys don't do it to each other. If I had a brother, I'm quite sure I'd suck his cock and let him suck mine." They giggled. "Yeah, I'd let him cum in my mouth and if he was really sexy, I'd let him fuck me up the bum. How would you girls like to watch me and another guy sucking each other's cocks and fucking each other? Would that be a turn on or what? It would turn me on, having you watch us." "That would hurt," said Twiggy. "No it wouldn't, because we'd stretch our arses with a dildo or a vibrator or something beforehand, even a small cucumber, then his cock wouldn't hurt." "Would it hurt if you stuck your cock up my muffin?" asked Twiggy. I could hardly believe my ears. Here was my little eleven year old sister apparently asking me to fuck her. "No," said Nancy, "because when a girl gets turned on, her cunt relaxes get bigger and anyway, it's designed to stretch. But you're way too young to fuck." "Why? I think if Tony wants to fuck me, he should be allowed to. It's not like I'd tell anyone." "If he's gonna fuck anyone, Twiggy, he's gonna fuck me." Holy shit, both my sisters were begging for it. I felt like the luckiest guy in the world. "Hold on, you fucking sex maniacs," I said. "Let's not run before we can walk." I removed my fingers from their wet cunts and sucked on them. "You both taste delicious," I told them. "Before we get into fucking, I wanna see you guys in some lesbian action." "Why?" asked Nancy. "It just that I've always wanted to see two girls having sex. In the nick, one of the screws would let us surf porn on his laptop, `cos he wanted to get his hand inside our underpants, and we'd always look at girl-on-girl porn, then at night I'd wank off to the memory of what I'd seen on the screen. Now I wanna see it for real. Come on, girls, if I'm gonna be nice to you and fuck you, you have to do your part. Lie down on the bed. No, Twiggy, the other way round, your feet up at the top. Now, you can inspect each other's muffins, cunts, whatever you wanna call them, and stick your fingers in them and then use your tongues. That's what grown-up lesbians do." I was treated to the exquisite sight of my sisters fingering and licking each other's cunts. Despite all the giggling, they seemed to like it. "Push your tongue in me," Nancy said. "Yeah like that. Is that as far as it'll go? Your tongue's too small. I need something bigger up there." "Like a cock," Twiggy suggested. "A nice big six inch cock like Tony's? That's what I want." She rolled away from Nancy and looked across to where I was sitting at the end of the bed, wanking my cock. "Licking a girl is fun, but right now I need a man's cock up me. Fuck me, Tony!" she commanded. "No, fuck me first!" Nancy insisted. "I'm older. I've been waiting longer. I want that magnificent cock up my cunt right now." I feel like a king. "Okay, Nancy first and then you, Twiggy. You're not too young, not as long as you really want it." "I do, I do!" "I'm gonna lie on my back, Nancy and I want you to straddle my hips and rub your pussy up and down my cock. Okay, yeah, like that. How does it feel?" "Oooh, better than your finger. But I want it inside me." "Okay. Lift up. Twiggy, take hold of my cock and guide it into her cunt. Oh yeah!" It slid right into her sopping wet cunt with no resistance, almost all the way in. She gasped, her face bright with excitement and she bobbed up and down, gripping me with her cunt muscles. I reached up my hands and caressed her micro tits and pinched her nipples, making her gasp again. Having been sucked off earlier, I was able to fuck her for several minutes without cumming and she came first, letting out a huge sigh and falling on my chest. "Are you alright?" Twiggy asked her, anxiously. "She's fine. She just came, that's all. Let her rest for a while." Twiggy's face disappeared behind her sister and then I felt her little hand caressing my balls. The gesture was strangely intimate. Oh, I thought, you little nympho, I'm gonna fuck your brains out in a minute. I'm gonna drive you crazy with lust. My inner paedo had fully awakened and I felt a wave of excitement run through me at the thought of fucking such a young girl. I rolled Nancy off me. My cock was pointing at the ceiling, wet with pussy juice. "Suck it clean, Twiggy, there's a good girl. Ooh, I'm getting another blow job, third one today. How do you like the taste of your sister's cunt on my cock?" She lifted her head. "Delicious, just like when I suck my fingers in bed at night." "Your turn to get fucked, you little slut. Come and sit on my cock." Twiggy's face was alight with excitement and she climbed on top of me and pressed her cunt against my cock, rubbing up and down, getting it wet with her own juice. "Okay, now, you know what to do, my sweet," I said. She lifted her body as I gripped my shaft and placed the tip at the gates of heaven. "Here we go," she cried, slowly lowering her weight. She was as wet as her sister had been and though her little cunt felt tighter, I penetrated her with no difficulty. About four inches slid into her when she stopped. "Oh, my God! I'm in heaven! I've been waiting for so long to be fucked but I never thought it would be this good. It's unbelievable. It's filling me right up!" I began gentle thrusts, taking care not to push too hard. I didn't want to hurt anything inside. Her face and flat chest were flushed and her breathing quickened. "Jesus!" said Nancy, "She really likes it. I thought it was all talk, but she's having the time of her life!" "Fuck me! Oh, fuck me harder!" Twiggy called, her eyes squeezed shut. She bobbed her little body up and down faster and faster and her obvious arousal was turning me on more than the physical sensation of her cunt gripping my cock. I was getting carried away. "I love you, Twiggy!" I called. I'd never said that before. "And I love you," she replied. "I love your magnificent cock. This is awesome! I want you to fuck me every day from now on." "What about me?" Nancy asked. "Do I get fucked, too?" Then little Twiggy, my eleven year old nymphomaniac, came, twitching and writhing as her orgasm swept through her. Then she collapsed on my chest, crying with happiness. _____________________________________ The following afternoon after lunch, with the girls at school, I was sitting in my room, thinking about the events of the previous night. Mum knocked on the door and came in. She was wearing a short, translucent slip and I could see she had no knickers on. "What's up, Mum?" "Did you enjoy yourself last night?" she asked. "I don't know what you mean," I said, my anxiety rising. "Yes you do, you fucking randy bastard. I was listening at the door the whole time." "What? You heard everything?" "You fucked them both, didn't you?" There was no point in denying it. "They were begging me." "I know. I'm not surprised about Nancy, but little Twiggy amazed me. She's a little fucking slut, though I do kinda like sluts. I'm a slut myself." "Why didn't you stop us?" I asked. "And spoil your fun? You deserved to have a nice time after all those months in the nick and the girls have to learn about sex sooner or later. I'm gonna put Nancy on the pill from now on, Twiggy too, when she gets her period. To be honest, I was standing outside your door with my hand down my knickers, cumming over and over, listening as you "molested" your sisters. Now molest me, Tony. I need you to fuck me." She sat on the end of the bed and fell back, lifting her slip up above her tits. Hearing her tell me about masturbating had got my cock more than half hard and looking at her lying vulnerable like that was a unique thrill. If she wanted to be fucked, then why shouldn't I oblige her. I ripped my clothes off and stood in front of her, my now perfectly stiff cock pointing at her face. "Suck it first," I demanded. "Oh, I love a nice big cock in my mouth and yours is perfect. You don't have to be sucked off by boys any more. Your Mum will be happy to do it." And my sisters too, I thought. She took my cock in her mouth and it was obvious she was an expert. As she sucked away, I thought that, as wonderful as this was, there was no way I was going to stop sucking guys cocks, stop letting them suck mine and fuck me up the bum. There's something special about sucking the cock of a good looking boy, taking him up to heaven and swallowing his cum. "Okay, Mum, time to get fucked. Lie back." Her feet were still on the floor as I knelt between her knees, dragging her down the bed until her bum was right on the edge. Her shaved cunt was already dripping so she didn't need any foreplay. I thrust my cock all the way inside her with a single lunge. She let out a huge sigh of happiness. There I was, literally a motherfucking motherfucker! A sister fucker too! I didn't give a fuck. It was all too marvelous to think about social taboos and all that shit. "Fuck me, Son! Fuck my hungry cunt! Slam that monster cock deep inside me! Oh, shit, I'm in heaven! I'm cumming, I'm cumming!" So was I. It was nice to be home. ___________________________________ After I'd recovered, I lay on my back on the bed, watching as Mum pulled her knickers back on. Spent as I was, she still looked really fucking sexy. She was still in her twenties and her tits hadn't sagged. "I must be some kinda pervert," I told her. "How many guys fuck their mums?" "Not every boy has a mum who's as sexy as I am, a mum who's fucking randy all the time. Since your dad left, all I have is my vibrator and my fingers and I used them all the time, but there's nothing like a stiff dick to make a woman happy." "Yeah, but I fuck my sisters as well. How normal is that?" "It's probably more common than most people think. No one wants to talk about it." "I'm a paedophile, an incestuous paedophile. If they talk, I'm gonna go back inside." "I'll make sure they don't talk." "I just couldn't help myself when I got home. They were both all over me, demanding to suck my cock and be fucked." "I know, I heard. I don't blame you, after all they're both so sexy." "Even Twiggy? She's still a kid really." "Yeah, but she has that special kind of sexy innocence, as though butter wouldn't melt in her mouth, then she suddenly becomes a raging little nympho." "Like -- you knew this? Did you ever . . .?" I'm too embarrassed to ask. "Yeah, with Nancy. She likes to suck on my tits and she lets me finger her." "Holy shit. Mum! She never mentioned it." "I told her to keep it a secret. Twiggy is all over me, too, always demanding that I kiss her little cunt like I did when she was a toddler." I laugh. "Kissed her pee pee?" "She loved it. I kissed Nancy's too when she was little and I sucked your tiny cock. It used to get hard and you'd laugh and gurgle with happiness. I'm just as incestuous as you are." "Jesus, what a thought! My mum eating little girls pussies! God, but I'd love to watch that." She thought for a few seconds, then said, "Why not? Tell you what, Tony, before the girls get home, why don't you hide in my closet and watch through the louvred doors. With the afternoon sun coming in the window and the darkness in the closet, they'll never see you. I'll tell them you're out and see if I can't persuade them to have some naughty fun. Wotcha think?" _________________________________ So there I was, naked in her closet, peering through the slats in the door when my sisters came home. They ran upstairs calling my name. Mum, lying naked on her bed, called, "He's not home, girls. He went out. He'll be back in time for dinner. Come in here, I want to talk to you." They came into the room and sat on the bed. "I have a confession to make," she began. "When Tony came home and you were in his room, I was listening at the door. I heard everything." I saw the horror on their faces. "Oh, don't be alarmed, you're not in any kind of trouble. I'm glad you got to suck his cock and let him fuck you. You were gonna lose your cherries anyway so it might as well have been Tony as anyone else. At least he loves you." "You're not mad at us?" Nancy asked, incredulous. "No, sweetheart. I'm very happy for you." "Oh, thank you, Mum," she said, climbing up the bed and lying beside her. Mum put and arm round her and I saw Nancy's hand sqeezing Mum's tit and playing with her nipple. Twiggy didn't look surprised. "I thought you weren't ready for sex, Twiggy, but clearly I was wrong. Did you enjoy it?" "I LOVED it," she gushed. "It was just as good as everyone said it'd be." "Come up here and gimme a hug, Sweetheart." Twiggy crawled up the bed and lay on Mum's other side. "Sometimes, Mummy gets lonely and randy and I play with my pussy with my fingers." "Yeah, we know everyone masturbates," said Nancy. "I told Tony I'd been listening. He was surprised, but when I told him I'd had my hand down my panties fingering myself, he got all excited and, well, long story short, he fucked me." "Oh, my God!" the girls chorused. "That's fucking amazing!" said Twiggy. "Are you jealous, girls?" There was a pause. "I'm not," said Nancy. "I'm still gonna let him fuck me anytime he wants." "Me, too," said Twiggy. "I want you to know that I still love you and I'm not jealous either. Do you remember when you were toddlers and I used to kiss your little pee pees?" "No," they answer in unison. "I suppose you were too young to remember. Well I did and you both loved it. Would you be surprised if I said I wanted to kiss them again, and teach you everything about gay sex?" Another pause as they tried to digest it. "But I'm not gay," Twiggy protested. "But you licked Nancy's cunt the other day. You don't have to be gay to like eating pussy. Lots of girls are bisexual. They like boys and girls." "Then I wanna be that, then. Bisexual. Yes, I liked liking your cunt, Nance, but letting Tony fuck me was better." "I think you should both get naked," Mum said. "I just love watching you undress. Ooh look, two lovely strippers, taking everything off, just for me. I'm getting excited." Once they were naked, they lay down beside Mum again. "You can lick my cunt, Mum," said Nancy. "Here, I'm gonna change ends and . . . no, better still, can I sit on your face? That way I can lean forward and play with your cunt." "Oh, perfect, my love." Nancy straddled Mum and lowered her body on to her face. "What am I supposed to do?" wailed Twiggy. "Finger myself?" "Do my tits," Mum suggested, "you know, like Nancy does, and then you can have your turn getting licked." "And licking you? I've decided that licking cunts is okay, not as good as a real fuck, but still pretty awesome." Nancy leaned in and I saw her tongue go to work on Mum's cunt. Twiggy watched the action while playing with Mum's tits. I couldn't help myself. My cock was so rigid, I just had to take hold of it and stroke it. The sight of my two sisters tangled up with Mum's arms and legs, the slurping sound of tongues, the sighs of contentment and the groans of ecstasy were too much for me and I came like a nine mil handgun, splattering the slats of the door with huge streaks of jism. I slid down to the floor, utterly spent and leaned back against the wall. What an amazing sight it had been, my darling sisters and my Mum in a lesbian orgy. I tried to remain quiet, but given the noises coming from the bed, there was little danger they'd here me. For about fifteen minutes I waited but they showed no signs of stopping their shameless sucking, licking, kissing and fingering. I grew bored. Fuck it, I thought, I'm outa here. I kicked the door open and stepped into the room. I heard the girls gasp with horror. "It's okay, guys, don't mind me. Carry on." "Tony!" the girls cried. "Did you know he was in there?" asked Nancy. Mum nodded. "You let him spy on us, you fucking traitor!" "I think it's kinda cool," says Twiggy, smirking. "Along with everything else, Tony's a peeping Tom. You can spy on me any time you like, Tony, as long as you fuck me afterwards." My cock is starting to get hard again. "No time like the present, my darling little sister. Lie on your back and spread your legs as wide as they'll go. Oh, what a lovely sight. Are you ready?" "Yes! Yes! Fuck me, Tony." Mum sighed. "I just love my kids!" The end.
