SIS CHANGED IT ALL SeXStoRY

Chapter 1 While I'm not the star of this story, it does start with me so I'd better tell you about myself. My name is Dean and I'll be starting my third year of college. No, I'm not a dean at the college, it's my name. I get at least three jokes a day about that. I have a year-round apartment here as I've doubled-up taking some summer courses to both get a double degree and try to finish early. We'll see. It was summer when all this began and my s****r had planned on visiting me before she went back to school. I had gotten a call from her which our mother took over almost as soon as she was on with me. "Yes, Dean, she wants to come visit you, we think it will be a good idea for her to really see how college is, how it works. And, Dad and I are taking a cruise. We just decided at the last minute, so it looks like Beth will be with you on Saturday, then for two weeks." Well, while I wasn't expecting a two-week visit from my little s****r, there's almost four years difference between us, I knew that my parents deserved a nice trip for themselves. "Well, be sure and do lots of fun things on the cruise and don't let anyone catch you two at it," I joshed. "Well, we might just do some wild things, maybe your mom will buy a new bikini when we're down there, I hear they've got some tiny ones. There's also a nude beach near where we're going for a day and, well...". "Do it, Mom, you'd look good," I told her and, yes, she would. My mother is still three years from fifty and she takes care of herself. She would get plenty of male attention on a nude beach and I told her so. "You mean my son wouldn't be ashamed if I strutted my stuff for all to see?" "The only thing your son wouldn't like is missing the chance to see you naked myself." "Oh, Dean, you're funny." "Maybe I mean it, Mom," and I left it there as she handed the call over to Beth. We ironed out her visit and all I needed to do was some cleaning and wash. But, what's new? My s****r arrived about one-thirty on Saturday at the airport and wanted to shower and freshen up when we got her suitcase in her room. My apartment is two bedrooms, each with its own bath. She came out about ten minutes later wrapped in a towel which showed more cleavage than I had remembered. "I thought I'd take you out to a little Italian place not far from here, f****y-owned, pretty good food, too," I told her, "But you'll need to wear more than that," I k**ded her. "Oh, I might get hit on if I went like this, huh?" "I'd even guarantee it, s*s, it's a sure thing." "So, you like?" she asked saucily as she turned back and forth. "What guy wouldn't?" "Okay but I'm asking you?" "You're my s****r, Beth, but, yeah, you've grown up pretty nicely, now go get dressed and we'll get a nice supper." She went off and in about twenty minutes was back. "I'm ready, how do I look?" She had on a halter and a denim mini-skirt that would give a hard-on to a corpse. "Wow, I can imagine what Mom would say if she saw you in that." She laughed as she turned around, bent over and flipped the back up showing me virtually all of her butt cheeks separated by a tiny thong. "Oh, she's seen it, Dean, she helped me pick it out." My s****r is about five-three and standing there, she looked super-sexy. This was new, she didn't used to dress so provocatively and her figure was equal to any girl I'd seen so far in college or even in Playboy, she was hot and she knew it. So, off we went to the little Italian place nearby where I was pretty sure we could have wine or beer with our food without any problem. We had finished the liter carafe of Chianti by the end of our meal and, while neither of us were d***k by any means, I think we each did feel nice. Then, back to my place where we had just walked back inside when my phone went off and it was my girlfriend, Amy. She had been visiting her parents at home and must have just gotten back. So, went in my room where I could talk and clicked on and talked with her. "Yeah, she's here. Are you coming over?" I asked. "Well, you better know that I'm horny as hell, Dean, and if I come over I'll want to fuck you. What about little s****r?" "Oh, come on, she's had sex-ed, she knows I have a girlfriend and, in today's world, that means we're fucking. So, come on over, we'll just excuse ourselves and go in my room. I'd never turn down sex with you, hon." She said she was on her way and I ended the call and went back out to the kitchen where I kept some daiquiris in the fridge and got two out and opened them. I handed one to my s****r and sat down to wait for Amy while we talked about growing up, high school, old friends and stuff. Then I heard Amy's key turn in my door and she came in. My s****r had not met her so I did introduce them and we all chatted for a few minutes but I could tell that Amy was here for a reason other than to meet my little s****r so I soon took her back to my bedroom and we had a rousing fuck, she was even hornier than I'd suspected. It was just after midnight when she got up and dressed, ready to leave as we were kissing goodbye. I was just in my boxers, in case Beth came out which she did. She was in a cut off tee and a tiny pair of panties and we both said goodbye to Amy, then I told her I was going to bed. "You mean I had to listen to you two going at it like it was your last time ever and now I've just got to go have it out with the dildo I brought?" She stood there asking me this, the under curve of her breasts showing under her tee with just the lower edge of her pink nipples. "Yeah, well, I guess so," I told her as I felt myself hardening looking at her, barely covered standing there looking at me. "Do you know you're sticking out of your boxers?" I looked down and she was right. I tucked myself in and she told me, "I shouldn't have said anything, I guess, it was looking pretty good to me. Better than my dildo. What do you think about making your little s****r a happy girl with that," nodding toward my middle. "I've already listened to what you can do, now I'd like to find out for myself." Chapter 2 There really wasn't any way to misinterpret that, was there? My little s****r wanted us to fuck and my dick was telling me, yes. So, I pulled down my boxers and she immediately pulled off the tee and slid off her panties as we came together kissing and feeling each other. She had her hand around my cock as she whispered, "Mmm, you're still good and hard. Let's see how it tastes," and she dropped down on her knees taking me in her mouth and sucking me as I ran my fingers through her hair. Oh, she was good, really good. She sucked me for a minute or two, then rose up, took me by the cock and led me back to her room and flopped on the bed, spreading wide welcoming me. "Mmm, I've heard you, now I want to feel you, feel that nice cock of yours deep in me, come fuck me, I've been wanting this for so long." I got between her legs as she reached down took my cock and pulled me to her. I pushed right up inside her as she raised her legs to shake her butt around. As I began moving in and out of her, I asked her, "You know, don't you that this is i****t?" "Mmm, yeah, well, it may be but you sure are making my pussy feel good. And, what the hell, that's what families are for, right? Making everyone happy." "Are you on birth control, geez, I almost forgot?" "Oh, yeah, for a while now, good thing, too," she snickered. I had really forgotten to ask her, I was so used to having sex with Amy, she's on the pill, that I only remembered when I was feeling close to cumming. I could not imagine the problems involved with getting my little s****r pregnant but, thankfully, that wasn't a concern. She lifted her legs up onto my shoulders as she wiggled her butt back and forth as I fucked her tight little pussy. My s****r was certainly lots more grown-up than I remembered. She was a hot girl who obviously loved sex and was relaxed and sure in her sexuality. She loved to fuck and she seemed proud of it. "Boy, my little s****r seems all grown up these days." "Oh, I was hoping you'd notice, I've been wanting this for a long time, you know." "No, I guess I didn't know," I admitted. "Well, I have and now I've got your beautiful cock inside me just wanting to cum in me, just ready to fill my pussy with your b*****rly cum." "I'm close to doing just that, the way you keep moving like this, oh, yeah, I'm really close." It was just about another minute and I was bucking into her spurting my cum deep into my little s****r. I knew we would be doing this a lot. "Mmm, I love your cum in me, I've dreamed of this since I was about eleven or twelve." "That young? Wow, girl, if I'd only known." "Well, now you do and I'm here for two weeks. I know you'll have to save some for Amy but don't forget your baby s****r, okay? I can't wait to tell Mom I've finally got your cock in me." "You what? Tell Mom?" "Yeah, she's known I've wanted to fuck you for a while now, she even suggested that I come for these two weeks, she knew I could get you into bed, she knows me pretty well." I really didn't know if she was telling me the truth or not, I mean it kind of sounded preposterous that she had told Mom that she wanted sex with me. I really didn't think she was being totally straight with that and, with my dick inside her, well, I went on to other things. "I guess this will be our little secret and I'll just have to try to pace myself to be able to take care of my girlfriend, too. I can kind of tell her that I'm entertaining you while you're here, it's actually the truth, right?" "Well, yes, it is entertaining, I must say, mmm," and with that, she started bucking up at me, forcing me deeper as she cried out, "OH, OH, OH, UH, mmm, mmm, oh, Dean, oh, we're gonna do this a lot." I kept fucking her, it just felt so good, she was so tight and nice and I was loving playing with her boobs. Afterward, we lay in bed, naked, playing with each other as I asked her more about if our Mother knew we were having sex. "You said, Mom knows you want sex with me, that she suggested you come for a visit and get me to fuck you. You were k**ding, right?" She laughed and said, "No, Mom and I talk about a lot of things. I told her that I've wanted to fuck you since I was in middle school. Little did I know, she's wanted to fuck you, too, but, well, we'll call them on the cruise this weekend, you can ask her yourself. They've got their iPad with them and we can Skype them on video." I told her fine, that we would but I was still seriously skeptical about all her talk about Mom knowing and Mom wanting to fuck me, too. Beth, as I remembered her, didn't have an overactive imagination but this really seemed far-fetched. We would see this weekend. They would be half-way through their cruise and it would be fun to see how they were doing. We slept together for the first time that night and I found that my little s****r had a sexual appetite more voracious than any girl I'd ever known. We screwed one more time before we went to sl**p then she woke me in the middle of the night for more. Then, waking up, she started me off with sucking me super-hard, then riding me until we both had huge orgasms. That started our day. So, as I was making my famous French toast, both of us still naked, I asked her, "Well, do you want to do some sightseeing today?" She was standing with me at the cooktop, holding my cock, rubbing the tip, as I flipped each slice. "No. let's just stay like this, okay? I've wanted you fucking me for so long that it's really all I want to do while I'm here. You feel so nice and hard," she said and gave me a squeeze. "s*s, having you naked all the time is keeping me hard, you've really turned into a hottie, you know that?" "Oh, I know that, Dean, I know that for sure. After we eat, we can have another fuck then a nice hot shower. I really know how you get cocks really clean. I practice at home a lot. You'll see." And that's exactly how we spent our day. Even though I usually don't lose my ability to maintain an erection, by that afternoon, Beth was sucking me hard each time for another go, she was just insatiable. I did get a call from Amy who wanted to come over later for a little fun and I told Beth. "Well, just don't be surprised if I don't come in and join you two. Think it would piss her off if I did?" There's a question I hadn't considered but it was surely something that had never come up before between the two of us. All I knew was that Amy was pretty willing to try new things in bed and I knew I probably wouldn't be able to control my horny little s****r's sexual impulses. "Does Amy like girls?" Beth asked. "Um, yeah, I know she had a pack of girls she ran with in her last year of high school and they were always in between each other's legs from what she's said. Why?" "Mmm, just wondered, that's all," and she pulled me back to her bedroom for more. Later, I went and got some Thai takeout and brought it back, then Amy came over and she and I disappeared into my bedroom. Beth and I, of course, had been dressed by that time, though my s****r was wearing, yet another skimpy little outfit. When I asked her about her clothes, she told me that's what she wears now. "Yeah, you're little s****r is not the same anymore, big b*****r. This is how I dress around the house, Mom even buys some of these outfits for me to wear. Even less, sometimes," and she gave me a big grin right when Amy came through the door. I hopped up and gave her a kiss, then we all sat around for a bit having some daiquiris that Beth had seemed to like, then, knowing why Amy was here, I took her back to my room and we quickly got undressed and into bed. Now, Amy was a real find, she simply loves sex and is ready just about any time, even three in the morning. I know, I've awakened her with my hard cock poking at her. And not only is she ready, she's eager, she loves to give it all she can, she's not one to lay there passively under you as you fuck away, no, she's meeting your every move. She hopped on my bed, spreading herself wide as I crawled up to tongue her. I licked and lapped a few minutes and she began pulling me up, telling me she was so horny, she wanted me to fuck her right then. I'm never one to turn down such a lovely request. So I got up and pushed into her as she dropped her feet on my shoulders and began fucking her nice and slow and deep the way she likes it. "Oh, yeah, mmm, mmm, oh, I love you fucking me like this, mmm, oh, so good," she groaned as I heard the door squeak a bit, then felt the bed move as Beth sat next to us, beautifully naked, and said, "Hi, guys, got room for another?" and bent over and began sucking one of Amy's boobs as she fondled the other. "Gee, Beth, we're getting to know each other pretty well, huh, just one happy f****y," my girlfriend said to my s****r who was sucking her nipple as her hand went down to rub my girlfriend's clit while I fucked her. She even dropped her fingers down to feel my cock sliding wetly in and out. That felt pretty sexy, I must say. I was just constantly amazed at my little s****r who has grown up into this hot sexy girl who just goes ahead and does something when she feels like doing it. Well, she's sure been fun to have visit and her time here with me has just started. I was just glad that my girlfriend is as open as she is and not the jealous type. At least so far. Then, Beth unlocked from her nipple and began kissing Amy, tonguing her mouth while she rubbed her clit. Amy was now moaning, her breathing heavy, as her hips began to buck and thrust against my strokes. I fucked her faster and harder as she groaned and trembled and shook under me. I knew it was a good one, a really strong orgasm, and soon she just lay there under me, a tremor running through her once in a while as my s****r and I continued to pleasure her. When Beth lifted off her mouth, Amy gasped, "Wow, I never expected the two of you to team up on me. That was fabulous. I've never had a guy and a gal doing me at the same time. Your b*****r never told me you liked girls, Beth." "Well, the truth is, I like everything, um, including my big b*****r. I hope you're not the jealous type," my s****r said as she reached over and took hold of my cock. "No, not me, not a jealous bone in my body. I'm for everyone having fun. In fact, I'd love to watch you two have sex. A b*****r and a s****r, that's something I've never seen before, it'd be cool." "Should we show her big b*****r?" Beth asked as she got up on her hands and knees. "Come, do me doggie-style, I just love it that way," and I got up and led my cock right up to her wet, plump lips and pushed inside. I just love fucking doggie-style and every girl I've ever been with loves it even more than I do. I think it must really feel good, maybe the angle my cock goes in or the depth I can push into, there's something they just love about it. For me, I love girl's butts and I love being behind them, rubbing their ass or the wet lips I'm fucking in between, it's my second favorite position. Cowgirl is number one in my book. So, I'm fucking my little s****r from behind as my girlfriend lays on her side next to us, her leg raised as she slowly fingers herself watching us. "You two are really sexy looking. b*****r fucking s****r, oh, it is so hot. How long have you been poking your little s****r, Dean?" she asked. "Just since she came to visit. Really, it never happened before this but I wish it had." "I'll bet he would have fucked me when I was ten if he'd had the guts to try," my s****r said back to me. "Well, all I care about is that I'm fucking you now and that I have a girlfriend who is so understanding." "The truth is, I rather like girls myself," Amy said as she moved her head up under my s****r so that her boobs were hanging down and she could suck and pet them while I fucked Beth from behind. Well, that gives you an idea of how the rest of the night went with the three of us. I even watched the two of them do each other for about an hour or so, seeing five orgasms between them. I'd never seen girls having sex together and I've got to say, it is one sexy, hot show to watch. I jacked-off while they were doing each other and got up over them when I was ready to cum and splattered them both; they just loved it, licking my cum off each other. Amy spent the night with my s****r and me all snug in my queen-sized bed and our sex began again in the early morning. Chapter 3 We three were now into all kinds of combinations, I especially loved my s****r up over me doing me reversed cowgirl as Amy crouched over my face while I ate her pretty pussy. But there were lots of fun things we kept coming up with so things never got dull. Finally, on Saturday, Beth and I had lunch and we were talking about our upcoming video call to our parents which they had scheduled at one o'clock. "So, you think Mom and Dad are having a good time on board their ship?" I asked her. "Oh, I can tell you that they sure will be. Mom had said she's going to look for a young guy to fuck and Dad's on the prowl, too." We hadn't talked much about our parents since she's come though there had been a few odd comments from her but I'd put those to an overactive imagination on my s****r's part. "You mean, like fucking around? Other people?" "Oh, yeah, you just don't know, Dean. The last year or so, well, things have been a lot different around the place, ever since I started with Dad." "Started with Dad? Like sex?" "Fucking Daddy, yes, oh, wait until you talk to them at one. They're going to tell you all about it. You just wait." "Now, come on, you can tell me more. You're really fucking Dad? Geez, and Mom knows?" "I'm fucking Mom, too, well, we're having sex. We all do it all the time." "You're putting me on, s*s, come on." "Wait, you'll see, you can ask her. I'll have her tell you. It all comes out when we talk to them. They sent me here to fuck you and get you into the f****y fun, Dean. Mom can't wait to fuck you, just wait and see." "This is all pretty crazy but I do admit we've kind of got rather different parents. If this is all true, what's got into them?" "Well, Mom says she just turned super-horny in the last few years and, well, so has your little s****r if you haven't noticed. I was fucking boyfriends and girlfriends and they pretty much knew about it, then one day when Dad was home, well, I just decided I was horny and, well, I got naked and had my Daddy." "No shit, Dad. And how did it start with Mom?" "Dad told me Mom had been wanting a lesbian hook-up, so I asked him if bi- was good enough for her. It was and that started Mom and me." "And so you decided you'd come and seduce your older b*****r?" "No, Mom decided I would. You'll see, it's almost time to call them." I fired up my computer and got Skype open and, right at one o'clock, there was a call from our parents. As the screen opened, there they were sitting on a sofa in their stateroom...naked. "Hi, Mom and Dad. Well, it worked. He was easy, Mom, I was fucking him right after I got here. Now, we're doing it with his girlfriend, Amy, too. She's really hot. Just wait until you meet her, Mom, she likes it both ways, just like us." "Hello, Dean. How do you like your old mom?" my mother asked as she put her hands under her breasts. "Well, it all seems a bit different," I told her as she stood up and rubbed down on her pussy. "This is for you any time you want it. How about seeing what your cock looks like these days?" I looked at Beth and she was up and taking her clothes off. "Come on, Dean, get 'em off, let Mom see how nicely her son is hung," my s****r urged. All this was new to me, there was never any hint of anything remotely like this when I was living at home. "This is all kind of different but, well..." and I began taking my clothes off. As I pulled my briefs down, my s****r took hold of my cock and pulled me up toward the camera to say, "Look, see what you've got to look forward to, Mom?" I could see Dad now standing as well with his long cock standing out as Mom took it in her hand. "Oh, have you measured it? Is he bigger?" our mom asked. Now I was beginning to understand why Beth sucked me real hard the other day, then held a ruler from my desk down to gauge my cock. "Yeah, he's seven and a quarter." "I win, Bethie, just wait until you get home, you're mine for a week." Mom cried. "What's that?" I asked my s****r who was playing with my cock as we all watched each other across the internet. "Oh, we had a bet on who had the bigger cock, you or Dad. I lost, I picked Dad and he's seven inches even. So, now I'm Mom's little slave girl for a week when I get back." "Yes, and I'll be making you suck your Dad's cock the way he likes it, too." "Okay, Mom, you won, I'm sure I'll have my head between your legs a lot, too." "You bet. Now, Dean, just so you know what your Mom and Dad have been doing," and with that she turned sideways, bent over and Dad took hold of his cock and came up behind her and pushed inside. What a show. "Mmm, feels good. Maybe you can fuck your little s****r for us, Dean. Do her doggie and we'll see who gets their lady to cum first. And no faking it, either." This from my mother who never ever used to even mention sex around us k**s. But, never one to turn down a pretty, tight pussy, I got up behind Beth and pressed up into her and the race was on. My s****r was twisting her hips around as I fucked her in and out and as I looked at my computer screen, Mom was doing the same twisting and turning around on Dad's cock. It was really surreal to be fucking my s****r while we were watching our parents have sex somewhere out in the warm, sunny Caribbean. Then, Mom started fucking Dad while he held still. She was empaling herself on his cock over and over, back and forth as her breasts swayed back and forth rhythmically. "Mmm, look at them, Mom's fucking Dad, let's try that, okay?" Beth suggested and I stopped while she began rocking back and forth on my cock. I placed my hands down on her butt with my thumbs right on her pussy's wet, shiny lips and rubbed up and down as she fucked me. "Oh, rub me like that, oh, shit, that feels so good, Dean, mmm, we might just beat them, don't stop doing that," she moaned. Well, Beth and I did beat them, my s****r had a great orgasm and soon after gave me one as well. Then we both watched our parents doing it, still much to my amazement. "Okay, Mom, you're my slave for a week when I get home. Just wait, I'll have you eating my pussy and sucking Dad's cock until we just can't take any more." "Well, this is worth it, your Dad is really turned-on from watching you two and he's giving me a great fuck." "Is it like this at home now?" I asked my s****r. "Oh, just wait, Dean, none of us wear any clothes any more and we just start with whoever we feel like at the moment. You'll love it. Think you could fuck your mom? I know she wants your cock, she talks about it all the time." "Well, Mom still looks pretty good, it's just something I've never thought much about but, yeah, sure, look at her, I'd do her in a minute." "I heard that, Dean, it'll take you a lot longer than a minute to get this pussy to cum, right, Dad?" "Oh, your Mom is good, Dean, she'll fuck your pants off, just wait," he said over the internet as we saw him shove into our mother cumming as she bucked on him getting off herself. It was something I never thought in my whole life that I would ever witness. But, well, it was sure sexy. I was about to do my s****r again, it had me that worked-up. "We want to watch you suck your b*****r, Beth. You two can do that for us, right?" Mom asked. "I'd love it," my s****r told them as I added, "Yeah. I would too," and Beth got down in front of me as we turned sideways so they would get a good view. My s****r's lips slid over my dick and she began to suck me. I've had a number of girls suck me off, the first was Barb Nelson, in the when we were seniors. She was really cute but she had quite a reputation for sucking off any boy who asked and I was one of them that asked. Not only was she skilled at what she offered, she also loved to do it in public places. What a girl. But my s****r, Beth, was even better as I was finding out once again as she sucked me for Mom and Dad's entertainment. "Oh, look at her, hon, I'll bet you miss your little girl sucking your cock, huh?" Mom asked Dad. "Well, you can suck it, you know I love it when you do," he told her. "Wait until they're through, I'm so hot watching them," she said as she stroked Dad with one hand and fingered herself with the other. As good as my s****r is sucking me, it didn't take too long before I was groaning and shooting her pretty, little mouth full as our parents applauded us from their cruise ship cabin. We ended the call and were sitting on the sofa, naked, playing with each other when my cell rang, it was Amy, "Hey, I've got just the idea for that horny little s****r of yours." I asked her what it was and she said, "She's such a horny girl, why don't we throw her a party. You know, a special party, one she's bound to like." There's something about Amy that will help you understand her idea...she loves to be fucked. And not just be me, by more than me. I've had six guys and myself doing her one whole weekend, the weekend she still talks about. I got up and went into my bathroom to talk with her about it. "Well, I could see who's around. Um, I know Jake is, and Lou, Cedric, um, don't know about Alex or Chris. Maybe Phil. Geez, I wonder if she's done a gang bang before. Maybe I should find out." "What, and ruin the surprise? Remember, I'd be there too, just to even things out," she giggled. "What about next Saturday, she's going home on Sunday, we'll sent her home with a pussy full of cum," I suggested. She agreed and I told her I'd see who could come and she started laughing at my use of the word, 'come.' So, I emailed my friends, attaching a pic file of my s****r, one of the many I had taken with her naked since she's been here, this one with her legs wide, exposing her charms to entice my friends to come and partake of my little s****r, and heard back from all but Lou and I remembered he was in Europe for three weeks with a study group so, poor devil, he'll miss fucking my s****r. Maybe another time. I suppose I should also tell you a bit more about Amy. One of the first things she told me the first time we had sex was that she loved sex with multiple guys and wanted to know what I thought of that. I told her that as long as I was one of the guys and that she didn't sneak around my back, I was fine with it. After all, I only had one dick and it couldn't keep fucking non-stop. She told me right then that I seemed just like the right kind of guy for her. So, since we've been together, all my guy friends have fucked her, lots more than once, and I've had most of her girlfriends, including a girl who waited on us in a restaurant once who Amy talked into coming over after she got off work so her boyfriend could fuck her. She told me on the way home how she'd offered me to this girl we'd never seen before that evening and that she'd be at my place about ten-thirty. She still visits from time to time. So, I have a rather amazing girlfriend and she plans on getting fucked just as much as this is for Beth. Of course, I went and told Beth that I was having a party for her to meet my guy friends and she wanted to know about each one. I told her they were all guys I'd met in college and what each one was majoring in. Jake was a tall, lanky guy who was a premed major and, as such, hit the books most of the time. But, he was slender and good-looking and I told Beth that I thought she'd like him with his wavy blond hair and crooked smile. Cedric I told her was black, medium-height and is on the intramural swim team. He's very muscular and very good-looking. I probably shouldn't say what her comment was but it had to do with his Speedo. Well, I've seen what's inside his Speedo, after all, I've watched it go inside my girlfriend and, well, I'll save that to tell you about when we get to the party. Alex was a finance major whose father owned a medium-sized manufacturing business and his older b*****r was the chief engineer there already. He was also about six feet tall, dark brown hair and a real ladies-man. She liked that. Phil, another finance major, had a mop of flaming red hair and a reputation the preceded him about what he was hiding in his pants. Beth told me she was eager to find that out if she could. No, I didn't tell her that she would have first hand knowledge of that soon after he arrived. I know that Amy loves to be fucked by him because he's the largest of my friends but I'll tell you more about that when the time comes. Then Chris, he was a chemistry major with the sharpest sense of humor I'd ever known. He always seemed to be surrounded by friends, many of them, young women who I suspected were there for more than his humor. I know Amy loves it when he fucks her because the guy can just go and go and go. It's like he almost never cums. I saw him screw Amy for nearly five hours straight once. He's got all kinds of girlfriends. And, of course, I told her that Amy would be there as well. "Wow, two girls and, what, six guys? Oh, just the right ratio, I like that." "Now, nobody said anything about sex, s*s. This is a party so you can meet some of my friends." "Okay but, well, who knows what might happen, right?" I told her that was true and we went on to other things as I knelt down between her legs. Chapter 4 Amy came over about four on Friday to help Beth and me get things ready for the party. Amy was already dressed, of course, and her outfit was especially skimpy. As soon as she let herself in, Beth took note with, "Wow, girl, you look so hot." Amy was dressed in a top from one of her bikinis and wore a short, pleated skirt. She did look hot, especially when she turned and flipped the skirt up showing us both her pretty little bare butt, a pink pair of vertical wet lips peeking back. "Shit, girl, you've got your fucking clothes on," my s****r cried, "I better rethink my outfit. What kind of party is this, big b*****r?" "Just some guys, that's all," I answered as I put out bowls of nuts and some cheese spread and crackers. So, we chatted about this and that getting everything ready, then Beth went off to her room to rethink her wardrobe. "Wait until she sees how we have a party, she'll love it, can the guys stay overnight, I hope?" Amy asked me while Beth was back in her room. "Oh, they know it goes until Sunday morning. Then, we'll take her to the airport and get her on the plane home a very happy girl." Then, right after six, the door opened and in walked Jake and Alex bringing wine and beer and I introduced them to my little s****r who they kissed quite long and hard. Then they took the stuff into the kitchen as I let in Phil and Cedric, shortly followed by Chris. As these last three were kissing my s****r, the first two came back out into the living room, each one naked, each cock swaying as they walked in. Beth let out a screech, "OMIGOD, LOOK, LOOK," and started laughing as they stood there. Now the other three came in, now naked as well, cocks all happily erect. Standing behind her, I had also pulled my shirt off and dropped my shorts as I went up behind her pressing against her as my arms encircled her, my hands cupping her boobs as Alex walked up to her, took her hand and put it right on his cock. "This is why we're all here, Beth. Let's get you out of these clothes" and between him and me, she was immediately as naked as we were. Right then, Amy walked in, also now naked, as the guys surrounded them both, hands everywhere. "Omigod, this is the party I've dreamed of, look at all these hard cocks," my s****r exclaimed as she was feeling each one. "I'd love to be the first guy, Beth," Phil said, as he lifted his huge cock up for her to hold. It had to be over ten inches, her eyes were wide as she admired his offering. "Mmm, yeah, oh, that may take a bit of work getting it in but let's try. Maybe get me over the back of the sofa here," and she took him by the cock and went to the back of the sofa, leaned over, spread open and he got up behind her. I handed him a tube of lubricant and he put a dab on the end of his cock and rubbed it up and down, spreading it on her pussy lips. "Just not my ass, okay, my pussy," Beth said as Chris got up on the sofa standing on the cushions, offering my s****r his cock to suck which she eagerly took in. I watched Phil begin pressing forward, working himself inside, pushing, retreating a bit, pushing more, each time getting a bit more up into my s****r as she sucked and sucked my friend, Chris. Amy took Jake by the cock and led him around behind the sofa and took up the same position as my s****r had while she had Cedric stand on the sofa so she could suck his cock. Soon Jake was fucking my girlfriend as Alex and I slowly stroked our cocks knowing we would have our turns sooner rather than later. Cedric was mouth-fucking Amy, something that she really likes if you don't overdo it and choke her shoving it in too deep. But Cedric was a gentleman, one of her favorite friends of mine. She loves his cock and, no, while he is black and there's this perception that all black men are huge, Cedric's cock is about six inches, just over according to Amy who has measured all my friends, it's the thickness she loves. She calls him 'fireplug' and the other thing she loves about him is that he can fuck her more times than any guy she's ever known. And, she loved sucking him because he can't choke her with it, then after, he can go and go and go. He's gotten her off five times once before he finally cummed. So I was pretty sure she'd want him next. My s****r made short work of Chris who quickly unloaded in Beth's mouth and she soon asked for Alex to step up on the sofa for his turn, she was obviously loving every minute of it and we'd just begun. Then Beth began squirming round as Phil fucked his big cock back and forth, now, shiny and glazed with her juices. She was moaning, then jerked her head back, letting Alex's cock fall from her mouth as she cried out, "OMIGOD, I'M CUMMING, OHH, OHH, UUNH, UUNH, uh, uh, mmm, mmm, oh, more, fuck me more, yes, oh, shit, I'm cumming again," and she trembled and shook and whimpered as Phil kept going. She took Alex back in her mouth, now moaning and sucking and moaning and sucking until Phil finally shot his load. He pulled out of her, making a slurping-pop sound as I moved up behind my s****r and easily shoved in on all the cum and juices inside my s****r and began fucking her fast and hard. She was wiggling her butt around, I knew she was liking this when she began moaning again. Just about then, Alex cums in my s****r's mouth as I fuck her from behind, going faster and faster. "Oh, Dean, omigod, cum, make me cum, oh, yes, fast, mmm, mmm," and she gripped the back of the sofa as I felt the spasms of her pussy around my cock. I kept fucking her until I blew my load. As I pull out, she's got cum running down both inner thighs. And we've just started. Cedric moved up to take my place as his stubby chocolate cock, already having deposited some cum in my girlfriend's mouth, now pressed into my s****r as he gripped her hips and began fucking away. Amy was now sucking Phil's huge dick, mostly working on the crown, I know her gag reflex and she can't even take me all the way in, so she was sucking Phil shallow but I knew how good she was so he looked pretty happy as Chris fucks her from behind. Well, I could go on and on, these two girls were fucked so many times that weekend we all lost count. Amy and I took Beth to the airport Sunday afternoon and helped her to the concourse. We were all walking a bit slowly, just so you know how much sex we had all had, Amy and I didn't fuck until the next Wednesday. On Friday night, I got a Skype call from home and there they all were, Mom, Dad and s*s, she and my parents all naked and enjoying each other as Mom asked me what on earth had I done to their daughter. "Oh, come on, Mom, we just had a little party for her. Did she tell you about it?" "Well, what she remembers. There was a good-looking black guy, really nice, she really liked him, and a red-headed guy that I want to meet, really big cock, she tells me. And some other guys. Poor Dad was so horny for his little girl and she would only jack him off. Well, until last night." "Yeah, Daddy wanted his little girl, Dean, seems like I'm in demand, huh?" my s****r said. "Well, she was sure a hit with all my buddies," I told them. "So we heard from Bethie. She was sure sore, she had the reddest pussy, we both had to kiss it and make it all better," our Mom said. "Now if I come visit, will you throw your Mom a nice party like that? See, I'm all wet just dreaming about all those hard cocks," my mother said, spreading open for the camera. "So I see, Mom, you come, I'll set it up," I told her. That I did about four months later, the guys loved fucking her and she seemed insatiable. They all insisted that I do her first which was our first. There have been times since and I've taken Amy home, too, to visit my parents. Yes, Dad fucked her more than once. Things had really changed in my f****y after my s****r started it all about a year ago. Yes, my s****r changed everything. Did she ever.
