Bill's Wife and Sister-in-Law A continuation of Bill's story By: The Wicked Dr. X Hi again, Bill here. It's been a while since I wrote anything down about my life with Marla. She's seventeen now, a year older then when I married her. Yea, I know, a girl of sixteen marrying a man in his mid forties just isn't right on so many levels. I swear I didn't plan it that way. Hell, it was actually her idea. Worse than that, her parents thought it was such a great idea, they paid for the wedding, and gave us a ten thousand dollar wedding gift! You gotta love in-laws like that, don't you? The thing is, Marla has about killed me. I've lost thirty pounds in the last few months, because she won't let me out of bed. I have had the luxury of being retired at a very young age, having made my fortune in the tech industry before the bottom fell out of the damn thing, and it gave me time to do pretty much whatever I felt like doing whenever I felt like doing it. That`s why I was out in my yard one lovely afternoon when she first walked by, hit on me hard and fucked my brains out, called her little sister Crystal over, and pretty much sucked the life out of me. It hasn't stopped since then. Come to find out, both girls had been genetically altered before birth by their almost mad scientist parents to be essentially sex machines. Something about letting women feel their full sexual potential. Well, one thing led to another and we got married. It's bad enough trying to keep up with a seventeen-year-old who really enjoys sex, but one engineered for it is enough to kill an old man. Add a horney little sister whose parents went a bit overboard with on the engineering side of her sexuality, and the bottom line is that Crystal is a bigger slut than her sister Marla ever was. It got so bad there for a time that I actually went out and got a part-time job in the summer just to give my poor body time to recuperate from the abuse they were giving me. Now don't get me wrong, I'm not complaining. The sex is the best a man could ever ask for. Marla is willing to do just about anything of a sexual nature. She's not into S/M, but neither am I. I couldn't think of hurting such a beautiful thing as Marla, and I couldn't imagine anyone wanting to. Anything else was potential fair game. She loved to dress like a blatant street whore when we went to the mall, or some such place, and hang off of me, watching the looks we got as we passed by. I even got threatened once by some incensed soccer mom who thought I had hired this young trollop for the day. Marla took ten minutes telling her off in no uncertain terms that she needed to leave a man and his loving wife alone. The poor woman was reduced to actual tears when Marla got through with her, apologizing profusely as she backed away with her fat old husband and homely kids. Later, after she thought about it, Marla agreed that maybe looking like a whore wasn't always a great idea in public and promised to tone it down a bit. She did, but you really couldn't tell. There just wasn't any way to make her look like a proper married young girl, and frankly, I don't mind. I like her the way she is. Looking like a seventeen-year-old whore, which is what she admits to being, is just fine with me. I don't know what that makes me, but to be honest, I don't care about that either. You see, the thing is, I actually love her. Not because she's the hottest thing walking the planet, but because she and I seem to have this love thing down pat. We would do anything for each other, and as young and innocent as she is, she seems to understand what true love actually is. Her sister, however, only understands sex, and her need for it. That's why when the little bitch gets really horney and she can't find anyone else, she comes to see me. I think she feels safe with me, and I guess that's better than picking up some stranger for her satisfaction. Now don't get me wrong, again, I'm not complaining you understand. There are things that Crystal can and will do that not even Marla will consent to, and frankly they're so twisted I don't even want to write them down for fear that I'll be accused of something evil that was her idea but that I can't prove. I mean, I've seen her put things inside herself that you wouldn't think would fit inside a fourteen-year-old's vagina, and still beg to have her ass hole fucked at the same time. The kinkier she gets, the weirder the things she seems to dream up for next time. Once Crystal gets that look of fire in her eye, I know I'm in for a very wild time with her. Oh, and Marla? Why, she's usually there, taking notes, sometimes real notes, sometimes joining in on the fun, and sometimes just waiting for her little sister to get done so she can have a go at me, especially if she thinks I really liked Crystal's latest perversion. I hate to admit it, but I usually do like her perversions, as sick and twisted as they can be at times. I think I'm getting as bad as she is. I finally built her a fuck machine, like I once saw on the Internet. Worked pretty well too, for all of two weeks. The last time I saw her use it, the thing was smoking. Crystal was climaxing for about the hundredth time just as the machine was screaming to a metallic, super-heated stop. I got to the plug just before the motor caught fire. Her comment; "Beat ya!" wasn't really a surprise. Now any right thinking person would have to be wondering about the kind of parents who would raise two very lovely girls to be raging sex machines, I know I did. Would you mind if I re-told the story of my encounter with their parents? No? Okay, well, it goes something like this; After Marla and Crystal both had their way with me for several hours the first time we met, I expected to hear from their family lawyer at least, or the state prosecutor at the worst, and was about blown out of my chair one afternoon when I got a questionnaire in the mail about their daughter's skills as sex partners. I think I mentioned that before in the first story. Anyway, I go to their house and cautiously ask, "What the fuck is this?" They explained the genetic manipulations they had done with their own egg and sperm to turn the girls into what they became after they were born, invited me to dinner and turned them loose on me. I barely made it to dinner that evening, but the grin on my face and the satisfied looks on the faces of their daughters seemed to please them. In the three hours before dinner the two of them had fucked me into a pulp. Both of them had climaxed more times than any of us had bothered to count, and the sheets on Marla's bed were soaked in sweat and cum, theirs and mine. A half hour before dinner, Astrid, their mother calls up and says we should get cleaned up for the meal. The girls and I climb into this huge shower, and Marla sits on a built-in seat with me on my knees before her, my face buried between her beautiful, wide spread legs, both of her hands pulling my head closer to her sweet cunt. I run my tongue up and down the inside of her slit, flicking her clit with the tip of my tongue, lapping hungrily at the warm, sweet lubricating juices her body is producing in copious amounts. The lips of her vagina begin to quiver, as do her thighs and I know I'm hitting all the right places. She begins to stroke my head, thrusting her hips into my face, her fingers tightening their grip on my hair as she pulls me closer to her. Then the groaning begins again, and her hips start thrusting harder, more insistently. Crystal lies down between my legs and begins sucking me for all she's worth, a finger fucking in and out of my ass. Now to be honest, I don't know which was better, that succulent sixteen-year-old pussy that I have my tongue buried in, or the incredible mouth of that fourteen-year-old wrapped around my stiff-as-a-board cock. All I know is that Marla's squeals of ecstasy as she climaxes yet again, and the sound of Crystal's sucking while my cock slides into her throat is driving me fucking crazy. I just know there is no way I'm going to climax again, not after the many times I already have. I figure my dick is going to go soft and the girls are going to be disappointed that they couldn't get me off one last time before dinner. I was wrong. I feel that all-to-familiar swelling in my balls; feel the rush in my head as the climax begins to explode throughout my entire body. My cock begins to gush cum into Crystal's hungry little mouth while her hands knead my testicles, as if to wring out the last tasty drop. Marla has my head in both of her hands, and she's pulling at me like she's trying to get my whole head into her pussy. As demented as I am about this time, I wish that could happen. What a beautiful thing, I think, to be licking the entire inside of that sweet canal, making this beautiful little girl scream with pleasure as I suck the sugary juices from her body. That's when I notice that I'm still ejaculating into Crystal's mouth. I've felt her swallow twice, and I'm filling her mouth again with my cum and it's squirting out of her swollen cheeks. She swallows again and forces my cock into her throat so that I'm filling her belly with my thick goo. The way she continues to suck on my cock it's plain that she wants more. Nobody climaxes like that, it just isn't natural, and no woman, or girl, is going to swallow that much cum without puking it up. These girls will. I figure there must be some reason for this and at dinner I asked their parents about it. What the hell, it's not like I'm going to embarrass them by asking. It seems that both girls appear to secrete some enzyme through their vagina's, mouths and anus's that boost the sexual performances of their partners. The parents are looking into synthesizing that enzyme, as soon as they can identify it. Anyway, after what was a very good dinner, (Astrid is a gourmet' cook, for what that's worth to you the reader) Marla decides that she would like to have an orgy. Her father, Hugh, thought that was a ripping good idea and began to slowly and lovingly peel the clothing off of Crystal. I could see that this was not the first time this had ever happened in this household. Then Astrid undressed Marla and then Hugh the same way before approaching me with the look in her eyes I saw in Crystal's just before my cock disappeared into her throat. I thought, what the hell, and grabbed the bottom of her short dress and flipped it over her head. I hardly need to mention that she was naked underneath that filmy white dress. As hot as she looked with the dress on, it was nothing compared to what she looked like with it off. Not an ounce of cellulite, and not a wrinkle anywhere. Her beautifully round and firm breasts turned up just a little at the tips of her pink nipples. She was an even match for either of her daughters. In as good a shape as I am, if I do say so, I had to admit to being the ugly duckling in this group. Even Hugh had the body of a twenty-year-old football player, plus being hung like a horse. Frankly, I was beginning to feel a little intimidated by this family, and the fun hadn't even started yet. Astrid cupped my face with her hands and leaned towards me, her soft lips caressed mine in a kiss meant for lovers of the most intimate kind, her tongue flicking at mine. I pulled her body close, running my hands up and down her waist, cupping her firm ass cheeks, up her back, and then encircling her. She writhed in my arms, moaning softly throughout the long kiss. Do I need to mention what was going on inside my pants? Didn't think so! Suddenly, I felt two hands around my waist from behind, fingers unbuckling my trousers, unzipping, exploring inside, and tugging the clothing down. It was very erotic not knowing who was having their way with me, but somehow I figured it was Marla. Astrid began pulling my shirt up and over my head just as I had done with her, and I felt one of the hands from behind me sneak between my legs and begin to stroke my hard cock very softly. She hardly touched the flesh at all, the grip was so light, so soft, but I could feel the effect as though her tongue were touching various spots. It was all I could do to prevent myself from exploding all over Astrid's tight belly. The hands began to grip my cock more firmly, and a head began to wedge itself between Astrid's waist and mine. I was right, it was Marla. I felt the tip of my cock being nibbled by those oh, so sweet lips, her tongue dancing around the head of it. A thrust of my hips drove it deep into her mouth and a groan of pleasure accompanied with a swirling of that talented tongue told me that she enjoyed it. Breaking the kiss for the second time, my head lolled back with ecstasy, and I could feel Astrid slide down my body, the tips of her magnificent breasts raking my chest. Joining her daughter on her knees, I could feel a second set of hands gripping my balls, kneading them gently, a second tongue licking at my cock, mouth sucking at the shaft. A squeal from across the room grabbed my attention briefly, and I looked over to see Crystal, her legs around her father's neck, her hands gripping his head and his tongue buried deep in her hairless cunt. Her groans, and whispers of "Please eat me, daddy" as her hips thrust at his face only added to the erotic tone of the situation. I can't begin to tell you how much I wanted to climax, but somehow I knew I wouldn't until they wanted me to. I kept thrusting my hips, shoving my throbbing pole into first one mouth and then the other, my hands on the back of both heads, my fingers tangled in masses of thick hair. Another shriek from Crystal and I saw her arms grip Hugh's head tightly, her tiny body bent over him, the long hair brushing his back, her hips grinding that precious mound into his mouth as she climaxed, shuddering violently. Gently he placed her feet onto the floor, holding her firmly while her body quivered in orgasm. She sank to her knees before him and he directed his huge member to her lips, and I watched in awe as the huge cock disappeared slowly into the tiny throat of his fourteen-year-old daughter. Her eyes rolled back into her head as he slowly fucked her mouth, Crystal's fingers raking his thighs, a thin stream of drool escaping her mouth, dripping down her chin. I had hardly noticed what was going on right in front of me. The mouths had stopped sucking me, and instead, Astrid was on her hands and knees, legs wide apart, her beautiful ass pointed at me. Marla lay across her mother, so that both of those sweet, glistening asses were there for my pleasure. Kneeling behind them, I slid my cock first into Astrid, amazed at how tightly her pussy gripped my cock especially after giving birth twice. I could feel her vaginal muscles grip me, pulling at the shaft like a mouth sucking. I bent over Marla's body as she slid forward, licking and kissing at her back and the globes of her tight bottom, finally running my tongue up the line between them, lingering at the tiny puckered hole. "Oh, yes! Fuck me there, Bill! Fuck my ass hard. I love it so much!" It wasn't a request. It was a demand. "Get your cock nice and wet inside my mother and fuck me!" I grabbed her thighs pulling her towards me, stroked that tight, beautiful pussy a few more times and pulled out of Astrid who slid out from under her daughter, grasping my cock and directed it to the tiny puckered hole of Marla's incredible ass. Slowly I eased forward, the tip of my glistening cock entering the girl's anus with unexpected ease. Her hips shuddered, and she thrust back onto me engulfing my pole, wriggling her ass, driving it deep into her beautiful body while she cried out with pleasure. "Oh yes! Oh fuck yes!" she screamed, "Fuck me! Fuck me harder!" Her body shook, and I thought she was going to pull the carpet off of the floor she gripped it so hard. Our hips met with loud slaps of flesh on flesh, which I thought sounded rather embarrassing at the time, but not enough to make me stop. Like you really needed to be told that! Obviously engrossed in what I was doing, I hardly noticed that our hip slapping was the only sounds being made. It finally dawned on me, and I opened my eyes for the first time in several minutes to see that the other three were watching us intently. Well, sort of. Astrid and Crystal were. Hugh was otherwise engaged, with Crystal squatting on his monster cock, and Astrid grinding her pussy onto his face. Sweat rolled down both of their bodies as they pleasured themselves and Hugh. A smile of approval spread across Astrid's face when she saw me looking at them. She even nodded; apparently happy with the way I was pleasing her squealing and moaning daughter. Suddenly, Hugh thrust hard at Crystal, all but throwing her off of him. It seemed to be a signal they both knew well. The tiny girl pulled away and sat next to her parents while Hugh lifted his lovely wife off of his face and rose to his knees in front of her, grasping his glistening cock in one hand and her face in the other. In what could only be described as a lion's roar, Hugh began to climax, his cock erupting a stream of ejaculate into Astrid's open mouth. At first I thought he was urinating into her mouth the stream was so long and continuous, but no, that was definitely cum. Some splattered onto her beautiful face, which she actually seemed to enjoy as she rubbed it into her skin. I watched in fascination as the mother of the girl I was happily ass fucking swallowed a huge load of her husband's cum, licked her lips and actually seemed to be begging for more as his huge prick disappeared into her mouth. Her cheeks hollowed out, and her head bobbed as the man's giant pole drove deeper into his wife's amazing throat. He grasped the back of her head and forced her to his belly, his cock buried completely in her throat. His body began to shudder and shake, another orgasm wracking through him, and he held her head firmly to his abdomen until it was through. It was the most amazing sexual scene I had ever witnessed. Okay, so I haven't witnessed too many sexual encounters in my otherwise ordinary life, but that just wasn't to be believed. In fact, I had actually stopped thrusting my hips while I watched them. I stopped fucking a gorgeous sixteen-year-old's ass to watch her parents have sex, they were that good. Marla's ass began to wiggle hard which brought me back to reality. She clenched her muscles around my cock, pulling me forward like she wanted to pull my pole out by the roots, giggling. "I told you I learned it all from my mother," she said. "She's good isn't she?" "They both are," I replied, resuming my steady strokes into the young, juicy little ass before me. "Mmmmm, you're good too, Bill. Just don't stop anymore, okay? Not until I tell you to stop. I promise to make it worth your while." "I'll do the best I can," I promised her without very much confidence. Hell, all she had to do was say the word cum, and I would have by then. I put my arms around her hips and lifted her body off of the floor, stood, carried her to the kitchen, bent her over the counter and began to fuck her sweet ass as hard as my hips could thrust. I must have been pleasing the little vixen since she began to flail about, screaming for me to make her cum, now! And then she wasn't begging any more, just screaming, and shaking, her ass grinding hard into my hips, grasping at my hips with her fingers. Her long hair swatted my face like a horse's tail swatting flies, sweat rolling down her beautiful back, lubricating my cock as it rammed unmercifully into her tight little behind. There was no fucking way I was going to hold out until she told me to. Suddenly, Marla wasn't moving anymore, or breathing, or screaming, for almost a minute. She was beginning to scare me. Her tiny fists pounded the counter one time and she exhaled loudly, her whole body shuddering in orgasm like I had never seen before. Her anal muscles clenched at my cock, gripping me tightly and I could feel my prick being pulled deeper into the sweet abyss of Marla's body. "Cum now, Bill! Please cum inside my ass! Fill me with your sweet sperm! Do it now!" No woman should have to beg for a man to climax inside of her, or so I found myself thinking. I let myself go, my swollen cock spewing wave after wave of ejaculate into the tender bowels of the most beautiful young girl I could ever remember seeing. The storm of orgasm seemed to go on forever, my hips jerked, thrusting in and out of her beautiful ass, pouring what seemed like gallons of cum into her, the stars flashing inside my head, my knees trembling, and still it went on, the pleasure receptors in my brain over-stimulated by whatever enzyme it was that she secreted. Never had an orgasm lasted so long. Somewhere outside my self, I could hear me begging for it to last forever, could hear me demanding that Marla be mine for the rest of my life, swearing my un-ending love for this young woman. It was several minutes before the effects of the most violent and intense orgasm I had ever experienced would wear off. I felt like I had been reduced to a mere shell of a body. The rest of me having been ejaculated into the bowels of this amazing young girl who stood over me, naked and smiling, a thin stream of my cum oozing down one long leg into a tiny puddle at her dainty foot. "I told you I would make it worth your while to wait," she said softly, "It was worth it, wasn't it? Just think. I can make that happen every time we have sex, but you have to let me marry you." "That's all you want?" "Yup." "What will your parents say about that, do you think?" She nodded towards the living room, and I noticed the smiles on the three faces that had been watching our performance. "It seems to us that our Marla has indeed found the man she wants to spend her life with," said her father, "She has spoken of nothing else since you two met two weeks ago." "Spoken about what?" I asked. "Why, marrying you, Bill. She has actually been quite the eloquent orator on the subject, quite convincing. It seems that the final decision is yours. We are here to support our daughter, and will abide happily by your mutual decisions." I'm thinking that these people are totally insane, giving up a beautiful sixteen-year-old girl to a middle-aged man to be his wife, in actuality his sex slave. Then I remember what they've done to her that caused this situation in the first place. I looked into her eyes, those beautiful green pools of lust, and started the barganing process. It's what I do. "What are you bringing to the table here?" I asked Marla, "What can I expect from you if we merge? What do you expect from me?" I wasn't going to be easy on her now. I'm still a businessman at heart. If she wanted to play a mature adult game, she needed to play like an adult, and I wanted her to understand that. "Expect me to be as respectable a wife as you want me to be. Expect me to take care of you and the house just like any other woman you would be expected to marry. I expect enough money to run a decent home in a proper manner. I don't expect to loaned out to your friends or business acquaintances without my approval, and never at the spur of the moment. I expect you to treat me like a woman, unless of course you want to treat me like I'm sixteen. Don't expect me to spend money like a teen-ager with a credit card. I won't do that, but please don't forget that I will have needs. I expect to finish school, married or not, and I would like to go to college, and I expect you to support me in that. Oh, and one last bit of information, Mr. Bigshot," she leaned close to my ear for this one, "you can expect me to be the best little whore you could ever want. I will fuck you any time, anywhere, for any reason. I will do anything you ask or want at least once unless it means major bruises or cuts. I'm really not into major pain for the most part, but I will listen and consider whatever you desire. In short, I'll be the best fuck a man ever had. Do we have a deal, Bill?" I looked into her bright green eyes for a few moments, considering the options, and then took her hand in mine. "Marla and I would like to announce our engagement," I said in the general direction of her parents. They were happy for us. "Before you marry my daughter," said Astrid in a low voice, walking slowly towards me, her hips swaying provocatively, "I would like to know what all the fuss is about. Maybe you need to experience an older woman one last time before you get attached to a little girl for the rest of your days. You do have a nice big cock, and I like big cocks very much." I sneaked a peek at my rapidly inflating member, and noticed with some curiosity that it had increased in size by a very noticeable amount. I think I even pointed at the darn thing in wonder. "Oh yes, that's another side effect of sex with the girls," said Astrid, smiling, "your cock gets bigger. It seems to be temporary, only lasting a week or so, but increasing in size every time you have sex." She pointed at Hugh's monster and I noticed that indeed it was larger now than when he had whipped the damn thing out two hours ago. Sex with Crystal had done it. "The thing is, that they seem to be able to regulate the enzyme consciously, so if Marla wants a bigger toy to play with, guess what's going to happen? To answer your nagging question, no it doesn't happen the other way; you're not going to end up with a one-inch penis if she gets pissed off with you." "That's nice to know." "So, what would you like from me?" I looked over to Hugh who nodded his consent to my unasked question. "Variety is the spice of life," I quoted, turning her around and bending that fantastic ass over the table where her daughter had just been. She still wore the black textured nylons and high heels she had on when she answered the door earlier that afternoon. I spread her legs apart reaching around her hip with one hand to just touch the outer lips of her vagina, my cock between her legs, brushing the bottom of her cunt gently. She began to move her hips trying to get my cock inside her. I wasn't going to let that happen just yet. I sawed back and forth, my pole rubbing between the lips of her vagina, teasing her, coating my cock with a layer of her lubricant while my fingers traced a circle around her clitoris, flicking at the firm bud. Her hips were grinding hard, up and down, back and forth, Astrid's breath coming in quick gasps as I touched her clit gently. I began to whisper into her ear, telling her what I was going to do to her, what I wanted her to do. She nodded enthusiastically with each demand, groaning her assent. Her pussy was as wet with her lubricating juices as I wanted it, so, spreading her cunt lips apart with my fingers, I slid the tip of my cock into her, reveling in the feel of her soft channel. Hearing her moan with satisfaction, I slid my cock deep into her belly, lifting her onto her toes with the force of my erection alone, grinding my hips into her ass while my fingers worked at the nub of her clit. She was amazingly tight for having given birth to two children and her vaginal muscles were strong, pulling at my cock, drawing me tightly into her. She squealed with delight, a hand covering mine, rubbing at her clit harder. I could feel her climax suddenly, her body trembling with every wave of orgasm that shot through her. She hooked her ankles behind my legs and began riding me; driving herself onto my cock with so much force I was sure she was going to break something. I slid my forefinger inside her cunt and squeezed her clit between it and my thumb, rolling the little knob. That about drove her crazy. She climaxed so hard that she actually began to cry. I pulled out of her and turned her to face me again, then shoved her shoulders, pushing her to her knees. Dutifully, she opened her pretty mouth wide, grasped my slippery pole in her hands, directing the throbbing pole between her lips. I watched her eyes roll back into her head as my cock disappeared into her throat, and was amazed when she grasped my ass cheeks and began to force me to throat fuck her. Her head bobbed up and down, her tongue licking at my balls as I thrust hard into her mouth. All the while one hand was between her legs, buried deep inside her pussy, fist-fucking herself. Jerking my cock out of her much too willing mouth, I pulled her to her feet again and lifted her onto the sturdy kitchen table, laid her down on it, strolled to where her head lay, tilted it toward me and stuffed my cock back into her mouth. It was then that I noticed that my cock was still gaining in size. It had gotten longer and slightly larger in girth. It barely fit into Astrid's mouth, and there was no way it was going to fit into her throat, so I took short strokes, jamming it into her, letting her suck at it, lick the head and as much of the shaft as she could. Suddenly, she pushed me away, my cock springing out of her mouth. "You're going to have to fuck my pussy if you want to climax, Bill," she said. "I know I said you could ass fuck me, but there's just no way that thing is going to fit inside me. No way in hell." I had to agree, and went to the other side of the table, pulled her hips to the edge and prepared to slide my pole into her. "Marla!" she called, "Get the yardstick and measure this beautiful cock, I can't believe how big he's gotten! What have you done to this nice man?" I had been so intent on Astrid that I hadn't noticed what the others were doing and I looked up in time to see my intended's juicy cunt being well eaten by her father, and her little sister lowering her tiny pussy over the man's huge pole, rising and falling driving it deep into her thin, four foot, eight inch body until she finally had taken it all and sat, squirming and grinding on his hips, her head thrown back in obvious ecstasy. Ever the dutiful daughter, Marla scrambled off of her father's head and went to find the measuring device her mother asked for. "I'm so thankful that the children love their father the way they do," said Astrid smiling sweetly. "I'm a little concerned that you keep getting bigger, Bill. We've not seen this before. Usually Hugh gets to the size he is during intercourse with the girls and stops growing. If you get much bigger it will make sex difficult for Marla especially. I think Crystal would be happy with it, but Marla is another story." I was thrilled that Astrid had such concern for her children's well being. To her credit, she did seem to know them and their limitations. That's about the time Marla returned with a measuring tape, the kind used by tailors. She began taking measurements as though she were in a clinic. "Sixteen inches in length and nine in circumference," she said proudly. "I want some of that!" she exclaimed with a hungry look on her cherubic face. "I hope you don't have any circulation problems, Bill, otherwise you're going to pass out from lack of blood to your other organs if that thing gets any bigger." "I hope not," I replied grinning back at her, "But if I do I'll count on you to give me mouth to cock resuscitation." "It's a deal," she said taking my now gigantic prick in both hands and aimed it between her mother's widespread legs, feeding it into the woman's vagina as though it were something she did every day. Who knows? Maybe she did. Before the head of it disappeared into her cunt, Astrid began to cry out, I thought in pain. I pulled back quickly, not wanting to actually hurt my future mother-in-law with my new weapon of mass destruction. "Please!" she begged, "Don't tease me! Shove it in! It feels so good to have such a big cock inside of me. Push it in all the way!" Now, you know me. I never turn down a woman's request to just shove it all the way in, so that's what I did. Astrid squirmed like a bass on a hook as I drove myself into her. She clutched at my cock, pulling it into her while Marla rubbed the nub of her mother's clitoris with her fingers, adding her saliva to the shaft of my pole. Marla's fingers clutched my ball sack, kneading my testis, gently pulling them and me closer to her mother's quivering cunt until all sixteen inches of throbbing cock had disappeared into Astrid's demanding body. I stood still, feeling the woman squirm, skewered on my sensitive pole. She was so soft inside, so fantastically smooth and warm. I could feel her vaginal muscles grip and release my cock, milking my rod, drawing me into her, and inviting me to follow. I had felt that before, in both of her daughters. What talented fuckers they all were. I don't know how to put it any better than that. Once a man fucks the Hilliard women it becomes hard to move on to anyone else. At least that's the way I figured anyway. I know I wasn't about to give up the chance to do any of them any time I had the chance, that's for sure. Meanwhile, my hips are ramming in and out of Astrid like a Formula 1 race engine's pistons and she's screaming like a woman possessed. Hugh and Crystal have stopped their incestuous coupling and are watching us like we were in a cage and being watched by curious anthropologists. That used to bother me somewhat, but now, I just don't care. I got a dong to be proud of and a hot woman to fuck. A little thing like being watched isn't about to slow me down, so I keep on hammering at her, not even caring whether I ever climax. It just feels so fucking good... Astrid has climaxed so many times she's lost count. I know because she told me. Me, and half of a city block, she screamed it out so loudly. I look over at Crystal and Hugh. They're applauding, for crying out loud, fucking applauding! Crystal is still impaled on her father's erection, happily bouncing up and down on him, clapping like the little kid she was. I have to admit I never expected applause for my sexual prowess, but under the circumstances I figured what the hell, and gave them the thumbs up sign while I continued to ram that big pole into Astrid's happy pussy while she squirmed and screamed. Marla, on the other hand, wasn't quite so happy watching me rip her mother's cunt to shreds. "You'd better save some of that for me," she demanded. "Hop up onto the table and you can share," I replied. She did, hiking her legs up to her chest, and pulling her sweet slit open wide with her fingers. I watched her finger her clit. What an erotic sight that was, seeing that beautiful little sixteen-year-old with her pussy spread wide open, waiting and wanting my cock inside her, stimulating her sensitive little bud of a clitoris. I waited until Astrid finished climaxing one more time and roughly pulled out of her, moved a step over and pointed the slippery beast at the entrance to her darling daughter's quivering snatch. Marla's sweet hole was literally dripping in anticipation, drops of her lubrication pooling beneath her. Easing forward, I guided the tip of my cock between the soft lips of her vagina. Relentlessly pushing forward, I could hear the sharp intake of her breath as my massive dong split her apart. She squirmed violently, splaying her beautiful legs apart, forcing herself to take me as though it were a matter of pride. I could see her beginning to sweat, the assault on her body was more than she expected, and worse, it seemed that as I bored into her my cock began to grow again! A smile began to spread across her pretty face. That wasn't pain I had seen in her eyes before, it was her straining to release the growth hormone! "That's better, that's what I call a big cock!" she exclaimed as her hips began to wiggle toward me. "Fuck me! Fuck me hard!" As curious as I was as to how big my prick had gotten, I wasn't about to pull it out of her. I felt it bottom out deep inside her belly and she squealed with delight when it did. There was still a couple of inches that wouldn't fit inside her which kind of irritated me a bit, I like feeling my balls slap against her ass, but what the fuck. I pulled out of her until only the head of my cock remained imbedded in her, sneaking a peek at my own dick as it slid from her hungry pussy, it was fucking huge, and there was a grin on Marla's face as she demanded that I ram it back into her. I'm thinking this can't actually be happening. The size of that thing must be killing her; it had to be eighteen inches long! Then it occurred to me that it was her doing that made it that big, so, I rammed it back into her just like she wanted. She screamed, I pulled out and rammed it back into her, and she screamed again, and again, every time I jammed that monster into her tiny body and she still wanted more. Faster and harder I jammed myself into her firm pussy until finally I could take no more. I started groaning, knowing that I was going to cum hard, and soon. Marla squirmed away from me on an outstroke and spun around on the table, her head over the edge, tilted down, mouth wide open. I poked the tip in between her lips and gave out with a grunt as my balls emptied into her delicious mouth, the cum splattering into her throat. She swallowed over and over, great streams of thick ejaculate dripped from the edges of her lips onto the floor. Astrid wiggled off of the table and knelt below her daughter, catching the dripping cum as it fell from her face, licking the girl's cheeks, and still it came, draining me once again. I was convinced that I would never leave this house alive. I would be reduced to an insignificant pile of dust to be disposed of with the filled vacuum cleaner bag. No one would ever know, and I didn't much care. I only cared about the insane orgasm I was having, and watching Marla's mouth fill with my cum, watching her swallow it into her belly while she stroked my cock as though coaxing out even more ejaculate to drink. It seemed like an hour before I stopped cuming although it surely wasn't. Marla released her death grip on my cock and let me sink to the floor next to her mother who immediately wrapped her mouth around my pole and sucked the last few drops of cum from it. "Hugh, we are going to have to enter this information into the journal. The girls are learning far too quickly how to regulate that hormone and I'm afraid that one of them is going to harm herself if she gets too anxious to climax." Hugh was far too busy to answer intelligently, Crystal's happy little cunt was grinding onto his hips, sucking the sperm from her father's big cock while he roared his own version of orgasm. It was two hours before either of us could stand without wobbling. It was three in the morning when I finally staggered home with Marla on my arm. She showed me some mercy by letting me sleep undisturbed until noon. When I woke up she was slipping clothing into a drawer. Sensing that I was awake she turned to face me dressed in that same almost there mini-skirt and white opaque belly shirt that you could see through with no problem. The same outfit she wore when we first met. I love seeing her tits through that shirt. "I didn't think you'd mind if I move in with you," she said in a very sexy little girl voice. "If it's a problem, please say so and I'll move it back home. If you let me stay I promise to make you a very happy man." I didn't have a problem with it. We were married three weeks later, just in time for school to start. I bought her a Corvette for a wedding present, with "Thompson 2" on the plates. She liked that. I just wish her sister would stay home more.
