Jeremy was slowly and steadily fucking me...over and over and over again. And it was an incredible fuck...like nothing I'd felt in years. Not since my wild and heady days of partying with my sister Robin. OH GOD...there he goes again with those moves. This is really going to be a lose-my-fucking-mind kind of orgasm. I'm shaking all over, my belly is just quivering, and Jeremy is so deep inside of me and moving so slowly that I can feel the tip of his massive cock nestling gently against my cervix. Like I said this is going to be an incredible fuck!! Why am I doing this? Why did I finally give in? Why am I betraying my husband Mark? OH FUCK!! That move he has feels so good!! The naked warm skin of his penis feels so incredible sliding against the wet slippery walls of my vagina. My mind is saying don't do it; it's not right. But...GOD DAMN...his penis feels so incredible sliding in and out of me. OH GOD, I'm cumming; and I can feel Jeremy's penis jump inside of me. He's going to cum too. I'm going to get pregnant. I know that as sure as I know that I've betrayed Mark. And this is what Robin has wanted all along. I know that now. Damn her!!! Years ago when Robin and I were first seniors in high school and later in college together we shared everything. We jogged together; and we both played field hockey and fast pitch softball together. We talked together all the time about school, and life, and especially about men. And most importantly we partied together...partied hard. Our mom, a simple woman, who loved to country dance and socialize with her friends, had two beautiful daughters whose libidos and hyperactive personalities often got them into trouble. Unlike our mom we were wild women. I was Robin's wingwoman and she was mine. Countless times we'd be dancing at a club or cutting loose at a college party. We'd drink a lot and many a time would end up in the bedroom or the back seat of a car or on the lawn in a nearby park, fucking like wild women. But we always did it in pairs. We covered each other from guy troubles. If some drunken fool who was handsome as all get out and studly to boot tried to take advantage or got a little too rough with one of us, I could always count on Robin to smack the shit out of whoever was hassling or hurting me; and I protected her the same way. In this way we could get as wild as we wanted to but still be safe. We were sisters watching out for each other. My sister Robin is blond, 5'6", busty as all get out with fine, big round breasts that just invite guys to squeeze them and kiss them and play with them. She is in great physical shape with an hourglass figure and a rounded booty that invites the guys' interest also. She has blue eyes, a cute face similar to Kim Basinger's, and a husky voice that just turns guys on. She graduated from Rowan University with a business management degree and immediately went into sales. She has several European pharmacy companies for whom she promotes their line of product through doctors but more importantly through conferences and trade shows where her flirtatious personality and bedroom manners have made many a good sale. It's not like she sleeps with guys to make a sale; she does so because she has a very active libido and likes to party hard. She likes sex and the sales she makes from guys she sleeps with have been a side benefit. Her clients love her success rate and no one has complained. She never married and never wants to; she's having too much fun with her friends and lovers scattered all over the country. I'm a 5'8" redhead with green eyes, cute round cheeks, an upturned nose, and a cute smile; my face looks look like Amy Adams. My figure is athletic like Robin's except that my breasts are not as large as hers albeit still more than a handful and more firm than hers; my boobs still stand right out and I don't require a bra. My figure is hourglass-shaped like Robin's with a little rounder booty than my sister and red not blond hair down there between my legs. We both keep our hair trimmed close; it makes us look shaved but without the itch of stubble. I like showing off all my junk down there without a mass of hair covering it all up; it makes for easy access. I too graduated with a business degree and I too pursued a sales career; and I too have been very successful. In my case I took my active sports life and used that to get into health spa/exercise equipment sales. I too have used my good looks and my flirty personality to make a good living. And yes I have bedded several customers, and, yes, this has netted me some great sales as well as a lot of laughs and fun. In our college days Robin and I had been very wild and there were several parties where either Robin or I or sometimes both of us spent a portion of the party stark naked, not knowing where our clothes were, and sometimes engaging in sex in public. We both loved the thrill back then. In our jobs this continued. Robin and I would party like crazy, usually find two guys, take them back to our hotel suite and fuck their brains out. With a little protection sex was great; and life was great. Much of this kind of grab-life-with-both-hands behavior carried on into our work. We tag teamed customers with our intelligence, our looks, our wit, our flirting, and sometimes our bodies. This life was what I wanted into my mid-twenties. Then I found myself wanting more. As I turned 26 I wanted a change. I was successful in my business and was having a great deal of fun in my personal life, but I wanted something different. I wanted an intimate personal relationship with a man who would be my spouse, my friend, and the father to my children. I could have kept on with multiple men but I wanted stability for the children I wanted. I wanted someone who would be there for me and support me and my children. I had seen several older saleswomen who looked lonely and tired as they got older, and I knew that having a solid family of my own would feel right for me for the future. Robin...she wanted things to stay the same. She saw no reason to tie herself down to a single man and had an extensive network of women friends upon whom she could rely. And she definitely never wanted children. She saw other saleswomen who were their own persons and who used men to satisfy their carnal needs but didn't need them emotionally. They all had their own extensive networks of women friends also. It was around this time that I met Mark. We dated for a few months and then got married. Initially while we were dating I still kept sleeping with other men; I still needed the variety. But quickly I settled down when I realized that Mark could have done the same but hadn't once he met me. Now, six years into our marriage we had two children, ages four and two, and a great marriage. Mark and I still went out clubbing, and I dance and flirt with other men. Mark knows that that is a part of me and encourages me, even to the point of suggesting I go clubbing in risqué outfits with no underwear on. He knows it's good for my ego and my sexy nature, and he knows I'm always coming back to him; he's my one and only. At the clubs I'll even flirt suggestively with attractive men on the dance floor, even allow them to touch me all over, but I always come back to my Mark. He finds it exciting to see me enticing other men as long as I come back to him. It spiced up our love life. It wasn't like the wild days of my younger years with Robin but it was good. We even invited Robin to join us frequently so she would feel included. Mark was attentive and caring, and he was a good lover to me and a good friend to my sister. My life had a little excitement but it also had the joy of both his love and the love of my children. For the first couple of years Robin seemed to be cool with this. She would visit us frequently and go out partying with us. Mark did have to get used to Robin walking around our house nude and entertaining guys in our guest bedroom rather loudly. But this had the bonus for me of making him very horny and having him roughly fuck my brains out, which I really liked as a change of pace. Given the noise coming from my sister's bedroom we felt comfortable letting loose and verbalizing the sex we would have. We actually found it arousing to listen to Robin and her lovers having sex while we were doing it too. So things were good. Mark would make suggestive comments about Robin's body and would also horseplay with her. He would get into towel fights or wrestling matches when one or both of them was undressed; sometimes he even got a big erection in front of her when they would wrestle. This drew suggestive comments from Robin; I thought she liked the attention Mark was paying to her, and his playfulness was innocent. He was just trying to fit into the dynamic of sexual closeness that my sister and I had shared for years. It seemed to be working, at least at home. On the road, however, Robin was still trying to get me so drunk that I would cheat on Mark, but I always controlled myself. Sometimes it was awkward when Robin would bring a guy back to our room and have sex with him only few feet from my bed. I have to admit watching some muscular, well-hung guy pump my sister into orgasmic craziness caused me to masturbate quite a few times to alleviate the sexual tension. But most often, since we usually rented suites I would retreat from the bedroom, text Mark to make that emotional connection with him, and, if all else failed, go for a midnight swim in the hotel pool. I never told Mark this, but there were times when I was so aroused that I would swim in the nude or just topless; I just needed to do something sexy and burn all the pent-up energy also. But except for a couple of times when some men joined me in swimming in the buff I was usually alone. The cold water and the vigorous laps would usually tire me out and calm me down. And even when the guys joined me for a naked swim nothing risqué happened. Even taking it this far, however, frightened me; I didn't want to ruin the great thing I had with Mark. He was my anchor and my rock. He was trying to include Robin in our lives and I wanted him in my life forever. In the third year of our marriage when I became pregnant with our son I think Robin realized I wasn't going to be her wingwoman anymore. Her behavior changed in two ways: she tried to get Mark to cheat on me with her and she now tried harder to trick me into engaging in sex with a stranger. As I said when she visited, Robin almost always walked around our house nude and so did Mark and I occasionally. Several times Robin popped into the shower while he was in there and tried to engage him in something sexual. She would grab his penis or try to push herself against him trying to get something sexual started. This was not the playful horseplay; this was sex Robin was after. Mark let me know each time. On two occasions she slipped into the shower and grabbed his penis and began stroking it. On one occasion she waited until he was rinsing his hair and slipped in and pressed her butt against his penis sticking out while he rinsed. And on the final occasion Robin waited until Mark had shampoo in his eyes, stole into the shower, knelt down and engulfed his penis between her lips. When he realized that it was Robin he shoved her away and told her to get the hell out of the bathroom. After that Mark had to take a shower with the bathroom door locked. After that didn't work Robin took every opportunity when she was alone with Mark to threaten him that she would have me knocked up by a man with a big cock, not that puny thing hanging between his legs. In fact she said she'd get me so riled up she'd have me begging for a man to fuck me silly with that big cock. These nasty, mean statements and threats Mark never told me about; he didn't want to upset me too much during my pregnancy. The last straw was when Robin caught Mark sleeping after one of his racquetball matches. She tied him to the bed, cut his clothes off and started to suck on his penis hoping to get an erection going so she could mount him and show me that he had betrayed me. I came home and caught my sister, butt naked, yelling at Mark that he wasn't a man and couldn't get it up. She was so enraged at his failure to get it up and stick his penis up her pussy that she was slapping his exposed penis and testicles. This is the scene I came in on. I knocked my sister to the floor and demanded to know what the fuck she was doing. "What the hell are you doing to my husband, Robin? I need you to get the hell out of my house. What the fuck is wrong with you? We've had a good thing. Mark's never done anything to hurt you. And I've been there to protect you and be your partner on the road. So why are you doing this?!" Robin shouted, "It's not the same Sherry. Before, I could share the stories, the good times, the partying, fucking two guys or the same guy in the same bedroom, and doing just about everything together. Now you're not there. I'm alone. And he's taken you away from me," she pointed at my husband still tied down on the bed naked. "And with that damn baby in your belly you will just drift further away from me." I had never seen my sister act so crazy. But I couldn't have her trying to torture my husband. I wanted her to share in the joy of mine and Mark's lives with each other and our future children, but I couldn't endanger Mark. I could no longer trust Robin to be my wingwoman. We parted ways and for the next four years we were civil in our communications but it was no longer special and fun. Fast forward to this year. Unknown to me Robin had continued to text Mark that she would eventually have me begging for a big cock to fuck me. She would find a way to make me cheat on him and would be sure to send me pictures of all the sordid details. Because my pregnancies were tough and because of the stress of raising new babies, taking care of my husband, and continuing as a sales representative on my own without my sister Mark never shared her texts with me. When Robin and I began finally communicating with each other her texts, emails and phone calls were all pleasant and friendly. I mistakenly thought everything was OK. It wasn't great like it had been in the past, and we weren't working together, but at least Robin was civil to me. Not knowing about her schemes and needing to get back in the marketplace to make some serious cash that we needed for our family I raised the idea with Robin of starting our partnership back up. Or should I say Robin had strongly suggested it, and frankly Mark and I needed the extra money. Mark knew that a big part of me wanted to believe that everything could be as it had been with Robin so he never stopped any of my plans, and he never let me know how badly Robin wanted to spoil our relationship. I guess he trusted that I would be strong enough. So after my daughter's second birthday Robin and I teamed up together again. We hit a big trade show in Las Vegas at which we had made big money in the past. The show was five days long, a long time to be away from Mark and my kids, but he and I needed the money to support our family and our future plans. For the first three days everything was great. During the days we moved around the crowds selling our respective stuff to the largely male customers; it was great to be back in the swing of things with Robin. And each night we went out for dinner and dancing like we had before to entertain potential customers or just have fun. We'd share dinner with our dates, have a few glasses of wine, and then head out to some nightspot that Robin usually was the one to select. Loud music, the crush of moving bodies, liberal amounts of sweet tasting alcoholic drinks that went to my head, and provocative touches from my dates or someone else on the dance floor all raised my libido. But I persevered and frustrated Robin, my date and sometimes myself when we got to the end of our evening out. I would tell my dates thanks for the good time but I'll be sleeping alone tonight. Robin would still bring her date into her bed and would still be only feet from my bed when she had sex with these men. This time I had ear plugs and turned over to face away from them and got good nights of sleep each night. Each morning she, her bed partner and I would get ready for the new day. By the third day I got used to walking around in the nude with these guys; there wasn't much privacy in our suite and Robin insisted on showering with her lovers. I didn't think anything of it, except for the stray comment about my looks or my figure. I would just laugh and try to be pleasant and dress as quickly as I could. Each morning Robin seemed to be cool with the fact that I had shut down the expectations of my date. And so it went the next day and the next day. Still we had great times during the day and fun times at night. Those earplugs that Mark had given me helped me to get to sleep while Robin was sexing it up with her male friends each night. I got restful sleep once I turned my back to what she and her friends were engaged in. And I felt I was covering for my sister by letting her know I was still nearby in case she needed to be defended or protected. Each of the previous days I had called Mark to let him know how things had been going with Robin. I told him she was trying to tempt me but I had been persevering well. I hadn't however told him about the lovers that Robin had been entertaining each night only a few feet from my own bed; I didn't want him to worry about Robin and her antics. But then this was no different than before. She was still my sister and in my mind we were again best buddies. I felt that Robin wouldn't let anything happen to me. She could take care of her needs as long as her guys didn't involve me. The fourth day of the conference started out much like the other days. But that evening Robin told me we were going to get together with some of the other women at the conference and visit a strip club with male dancers that was rumored to be quite the place. It was rumored that the dancers were all very handsome and well-hung, were great dancers and entertainers, and would get very up close and personal upon request. I for one was looking forward to not having to fend off men who wanted to feel me up and to just spending a fun night out with the girls. I called Mark before we left and informed him what we were planning that evening as I had every evening. He wasn't concerned as I and my female friends had gone to strip clubs before; he knew it was just for the fun. That's all it would be for me. The club turned out to be a total turn-on as several of the female customers got invited on to the stage where they were enticed with both whipped cream and the sheer incredible size of the male dancer's cocks to suck on them. The dancers all ended up nude and once they were nude they would circulate among the women. They would grind against the women in the audience, drape their cocks over those same women's shoulders and in their faces, and would entice them to suck on their incredibly long and thick penises. A lot of the ladies at our table did take a taste of one or more of the dancers, and one of the women, Alice, a married mom, actually disappeared with one of the dancers into a separate room draped with thick red velvet curtains. Robin yelled into my ear over the noise that in that room the customers could get the full treatment, and then she winked. I later discovered that the full treatment meant having intercourse or receiving cunnilingus from one or more of the dancers depending upon how much you tipped them. I have to admit that the sheer fun of the moment as all of my tablemates engaged in wild actions and then finding out that Alice, a married woman, was actually being fucked by one of these hunks, got me all hot and bothered. It was at the wrong moment when I turned around and my face bumped into the biggest chocolate brown penis I had ever seen or encountered. Robin introduced the very handsome black man as Jeremy. Jeremy leaned over to talk to me. He was completely nude. His body was slender but very muscular. His hips and thighs were very tempting to touch as was the sizable penis that was growing out of his flat muscular groin. His pubic hair he had trimmed short not shaved on his belly, but his testicles and penis were silky smooth. This highlighted the size and shape of his cock and testicles. Robin Gets Her Revenge "So this is the prettier sister that Robin has told me about. My goodness but you're beautiful," his penis bobbed a little as it got a little stiffer. I wondered if that was me that was causing Jeremy to get aroused. He put his arm on my chair and on my shoulders as we talked. He smelled really good also; he had on enticing cologne that I really liked; it was the same as what Mark wore. He was so close to me that I couldn't help noticing how handsome he was and in what excellent shape he was. I was surprised to find out that he was in fact a sales representative for one of the companies at our show and made the same circuit of trade shows and conferences that Robin and I visited. He did this stripper activity because it gave him a kick to dance naked in front of hundreds of screaming women. He did this in several big cities like Las Vegas via arrangement with the different clubs; in each club he had auditioned by entering an amateur dance competition and winning each one. He had met Robin that way last year and they had soon become friends. They would often have dinner together. And yes he had slept with Robin. At this point in the conversation Robin, listening in on our conversation, interjected, "Oh my god, Sherry, he is fucking fantastic in the sack. I about lost my mind the night we slept together. He's so big and so skilled!!" Jeremy responded with embarrassment, "Robin, you're embarrassing me. I'm just another guy who is unattached. I like it that way." During this exchange I glanced down and was in awe at how big and stiff Jeremy's cock had become. My goodness!! I started getting warm and then found myself getting wet between the legs. Seeing Alice return to our table looking absolutely rosy and happy I blurted out a question, "Jeremy, do you visit the room with the red drapes with some of the ladies at your shows?" Smiling and placing his free hand high up on my thigh in a place that made me conscious how close his fingers were to where I wanted him to touch me, he asked suggestively, "Why? You interested?" I almost jumped at the offer and then I stopped myself. Jeremy continued, "I rarely do that, but you are as beautiful and delicious as Robin has said you were." I turned and smiled my appreciation to Robin and I felt warm inside at the thought that maybe we could stay close buddies like we had before Mark. "If you want I can give you a private, all-night experience. I would absolutely love to do that for you." As if his thoughts took physical form Jeremy's penis stiffened harder and the tip of his penis was now unsheathed from his foreskin. It was very hard to resist, but then I thought of my kids and Mark and I stood up and excused myself. I quickly headed to the Ladies Room and splashed my face and neck with cold water. When I looked in the mirror my skin was a bright red. God, but I wanted to fuck that man!!! I had to get control of myself...for Mark...and for the kids. Thank goodness; the tense moment had been broken by me standing up and by splashing copious amounts of cold water on my face and my neck.. When I returned to the table I noticed that Jeremy had moved on to other tables. My goodness but his firm, round, ebony-skinned butt was a delicious sight!! I was grateful he had moved away. When I sat back down at the table Robin looked a little miffed. "Sherry, Jeremy was putting his heart out there for you. Why did you leave? It would have been one fantastic night and Mark wouldn't have to know. Look at Alice...happily married because her husband George doesn't know that she occasionally gets off on the road. It's made their marriage better. She's full of life and energy, and George thinks his wife is a tiger in the sack because she's missed him. It works out for everyone." Robin didn't understand. It would be a lie that I would have to live with. "Sorry, Robin, I just couldn't. Sorry I disappointed you and upset Jeremy. He seems like a nice man." We left shortly thereafter as all of us women had to be back at the trade show looking perky and making those sales we all needed for our income bright and early the next morning. The next day, the fifth day, was pretty much the same as the day before. Robin and I tag teamed multiple guys and made big sales. Robin suggested that we should really put on the dog and let two guys who were loaded take us out to dinner and dancing at one of the poshest places in town. A nice lobster and steak dinner and some refined dancing I could handle so I agreed. As usual I called Mark but got no answer so left a long voice mail for him and the kids. I missed them and would be glad to be back home the next day. I would have a whole week off and then on to Atlanta for one of our biggest conferences. That would be yet another five days away from the family. But at this point I was looking forward to big sales despite feeling exhausted from the non-stop day and night activity. It had been a long time since I had seen so much action. I needed something to help me get through this trip, the time at home and the trip the next week in Atlanta. Telling Robin about how exhausted I felt Robin suggested I take one of the medications she was beginning to market to various doctors on a trial basis. It hadn't been approved by the FDA but she felt it would. She told me it was formulated especially for women and would raise my energy levels without any side effects. It came from a German pharmaceutical firm. The pills were pink and heart-shaped in order to be appealing to women. She had samples that could be handed out with warnings that it hadn't been approved, but she had several studies that said it was safe. As I said I trusted Robin's opinion especially on pharmaceuticals. That morning I took the first tablet and by that evening as we got ready for our double date I did feel slightly more energetic. It was while preparing to change that Robin suggested I wear my sexy blue clubbing dress and forego any underwear. The blue dress was a slinky, wraparound dress that without a bra, panties and hose left almost nothing to the imagination. But I surprised myself by responding, "Sure. Why not?" I found myself wanting to dress a little sexier than the nights before. Dinner was fabulous and the club we went to was right down the street from the restaurant and was restricted to certain members of the public. As Dan and Brett's dates Robin and I got in. Dan and Brett owned several medical distribution wholesalers and were raking in the dough. We dined on champagne and continued on champagne at the club. Feeling the champagne go to my head and having memories of Jeremy's body and manner from the night before fill my mind sexually, I was feeling a little out of control. Although I was feeling much hornier this troubled me. I didn't want anything to happen, but I did. So I insisted with Robin that neither guy was coming back to the hotel room tonight. I lied to her and said that I wanted to be rested for our flights back tomorrow. But a part of me was feeling so randy that I feared what might happen. So when that point in the evening arrived when our dates, having forked out a ton of money on us were hoping to spend the night with us at either their rooms or ours Robin talked to them and we all headed back separately to our respective rooms. I was pleasantly surprised that Robin had persuaded the guys to stay away. She was protecting me. Back in our room I stripped naked, brushed my teeth and gargled and slipped between the sheets. Thank goodness I wouldn't have to wear those earplugs for at least one night. Later that night I dreamed and it was an erotic dream. Jeremy, Brett and my husband kept changing places. They each were caressing my skin and placing soft kisses on my shoulders and neck. As my dream progressed I felt Mark separate my thighs and he began to enter me from behind. With a start I realized this wasn't a dream; it was fucking real!! I fully awoke and found Brett's nude body flush against my back and his stiff penis starting to enter me. I screamed, jumped off the bed and slapped him silly. I was pissed!!! "I just thought you wanted it like your sister. You were pretty friendly last night, you weren't wearing any underwear and you were sending out all kinds of sexual signals; Robin said we should come back to the room later so that you could rest a little before the fun would start, and you were sleeping here all naked and uncovered. Sorry, Sherry, but what was I to think." He paused, clearly upset at my reaction, but I also noticed that he was checking me out standing there butt naked. He still had a major erection. He continued, "And Robin said you would like to have some 'quality time away from your old man'." After grabbing up a blanket to wrap around myself I glared at Robin who was standing there with Dan, both of them naked and looking disheveled like they had just been messing around. "Sherry, I'm sorry sis. I think that Brett misunderstood and I'm sorry I lied to you about inviting the guys to come back to our room. I was planning to have them both to myself, little sis. But you were totally naked over there and uncovered and we all noticed that your hips were grinding something or someone and you were moaning suggestively so I thought Brett might be able to assist you with what you were dreaming about." It all sounded pretty fishy but I gave Brett, Dan and my sister the benefit of the doubt. Dan, Brett and Robin slipped back into her bed and I went out on the couch in our suite to sleep safely in case Brett got any more ideas about me. The next day we headed home. At home my husband took care of everything for me; he washed my clothes, drew a warm bubble bath, and made a scrumptious dinner. The medication which Robin had given me had perked me up considerably. That first night back after we put the kids to bed I made love to Mark like I hadn't in a long time, not since Robin and her lovers had aroused us to our own loud lovemaking. It was a good thing the kids were sound sleepers. Both Mark and I were repeatedly moaning and groaning as we made love throughout the night. Mark even asked me, "Wow, you should go away more often. What's gotten into you? You're fantastic, baby." "Nothing's gotten into me," I lied. I couldn't tell him about Brett's penis being inside of me just the night before. I figured it would only trouble Mark and, after all, I had thrown Brett out of my bed and he had been nice after that as had Dan and my sister Robin. I was still believing in my sister...naively it turned out. The next several days were wonderful as I spent as much time as possible with Mark and the children. Each day I took the pink pill as Robin had suggested; I liked what it was doing for my energy levels and liked the bedtime side effects with Mark. During the days I spent time with the family and prepared for the trade show in Atlanta. It was a big one which covered all dealers in the South, especially Florida and Texas, big states for exercise and sports medicine equipment. But too soon I was getting on a plane and flying off to Atlanta to partner with Robin and to spend five days of intensive sales and entertaining of our potential customers. Our hotel room was a suite as always. This was a good thing as far as I was concerned. It would give me a place to retreat if my sister entertained her gentlemen callers with too much noise and action. Although the renewed energy I felt was also raising my libido to levels I hadn't experienced since my college days, I didn't want any more encounters like what had happened on the last day in Vegas. The first three days of the trade show went smoothly...kind of. During the days Robin and I worked our magic with customers and lined up multiple orders for what we had to sell; it was great for business. However I was finding it hard to concentrate due to feeling almost constantly horny. In fact on the second day I excused myself at lunch time, went back to our room and masturbated to relieve the tension that was building up inside of me. As I fantasized I started out with Mark in my thoughts but then began to think of Brett who had actually had his penis up inside of me and then lastly Jeremy with that beautiful brown cock of his standing out hard from his taut almost hairless belly. It was with thoughts of him pushing that gorgeous cock up inside of me that I orgasmed. I shook and shook and shook with a very intense orgasm. I had clenched so tightly during my orgasmic spasms that my butt cheeks ached slightly. My pussy...it was thoroughly soaked with the cream pouring out of my vagina. I had to grab a towel and dab up the fluid pouring out of me. Wow, what a great orgasm! This totally relieved the tension for the rest of the day, but by evening I was feeling very horny again. That evening I asked Robin, "Are you sure these pills I've been taking are all right?" "Do you have more energy than before?" I responded, "Yes...but." "But what?" "Well, I'm finding myself getting very horny. Almost all the time." "Girl, you've been so long with that one man that you've forgotten what increased energy does to women like you and me. More energy...more libido. It's natural, sis. If you want you can stop the pills, but with the sales you've been racking up you might want to wait until Friday when you head back home." I thought about it for a moment and surmised that I could hold out for the four remaining days. I'd just be doing a lot of masturbating. Little did I know that Robin was lying and I would suffer greater and greater need for sexual release in the ensuing days and that she would have more tricks up her sleeve from her little case of pharmaceuticals. On the second evening we headed out for dinner and dancing like we had in Las Vegas. On the first evening I had begged off, wanting to study up for some potential clients the next day. My date was very attractive. While dancing I found myself leaning into him and allowing his body and his hands to press against mine. The thrill in my belly was fantastic. I was damp most of the night from arousal. And while dancing I found myself pressing my body hard against his. I enjoyed the feel of his stiffening penis as he pressed against my belly and between my legs. Robin like before had selected our dates. Michael was a tall, muscular Mediterranean man with jet black hair, dark eyes, the hint of a five o'clock shadow on his face, and olive colored skin. Robin's date, also a Michael, was completely different. He was a redhead, an actual Irishman, with whom Robin had done repeated business. They both liked to party and Michael had suggested Italian Michael as my date. When the time came to head back to our room, Robin suggested that the guys come by later after I had fallen asleep. She made a big deal about me being married and being true to my husband. But Robin said she would love to have both men share her bed if they were not afraid of a threesome. I was a little suspicious based on what had happened in Vegas, but I let it go. I would be bundled up in PJ's tonight. Before he left, however, Italian Michael said to me, "Sweet dreams, luscious Sherry. Sorry it can't be you tonight. Damn, but you're beautiful." His complement went right to my head and to my humming pelvis. I really wanted to invite him into my bed badly, but I resisted. Robin and I headed back to our room and I was soon undressed, into a pajama top and pajama bottoms, no panties, and was soon asleep. In a half daze I felt someone snuggle against my back. I didn't resist. I found myself enjoying the warmth and manly scent as a strong arm wrapped around my shoulder. I soon dozed off again. It was the next morning when I woke up saw the same arm draped across my chest and felt warm breath on my neck that I realized I had slept with Michael. The thick dark hair on his arm told me that. But as I woke up from my sleep I quickly realized that my top was gone. His arm was against my bare breasts and his left hand was cupping my right breast, almost cradling it; my nipple was quite erect and aroused. And then I realized that my bottoms too were gone; I could feel Michael's penis nestled against my bared backside. Unlike the week before and maybe because Michael hadn't tried to have sex with me I calmly slid out from under his arm to go to the bathroom and to prepare for a new day's activity. As I stood at the side of the bed I lifted the sheet so I could gaze at his penis. Oh my, it was beautiful to see. It was about five inches long, about an inch and a half across and was tipped with a sizable circumcised mushroom cap. His belly and his testicles were covered with thick dark hair. He had awakened while I was studying his groin and startled me a little when he said, "Do you like, Sherry? How about if we share the shower?" He said this quietly because the Irish Michael and my sister Robin were entangled on my sister's bed and still sleeping; or so I thought. Italian Michael stood up and his cock was even more enticing as it hung partially erect. Gosh, but I wanted to run into his strong arms, smell his scent, run kisses down his hairy torso and encircle that magnificent penis with my lips until I felt his semen jet down my throat. Instead I put my hand on Michael's shoulder and said, "Michael I really appreciate that you simply slept with me last night, although I don't know if you or I removed my PJ's. That's embarrassing and I apologize. It was very nice, however, to wake up next to you all warm and cozy and not have you trying to force yourself on me. But despite what Robin might have told you, I have every intention of keeping faithful to my husband, Mark." And with that I headed into the bathroom to shower and prepare for the day. I was soon joined in the bathroom by Robin and her bedmate Irish Michael, who not being as nice as Italian Michael, tried to climb into the shower with me and spent some time ogling me while I showered. But then he and Robin entertained each other after I left the shower. Italian Michael had already left. I dressed and did my makeup and hair for the day. The third day was marvelous for sales. I had lunch with Italian Michael and he brought me some new customers. I appreciated his kindness, but my thoughts became mixed up with pictures of his dark, taut manly body stretched out against the white sheets of my bed and what his body had felt like spooned against mine. It was almost too distracting. Several times I had to force myself to bring my attention back to my customers surrounding the lunch table. That evening fortunately Robin said we were going out with the girls, almost the same crew of friends with whom we had partied back in Vegas. Well at least there wouldn't be any men trying to get me in the sack. Again we visited an incredible strip joint which had nude male dancers who would go as far as you wanted, as long as you were willing to do whatever in front of everybody else. They also had a private dance room like the club in Vegas. Again the entertainment was bawdy with several women being invited or even dragged up on stage to suck some dancer's penis in front of her girlfriends and the whole audience. This time, however, I became totally aroused and began to entertain thoughts of visiting the private dance room to suck off one of these incredibly handsome and hung dancers. Again Alice, the married mom, was in our crew and again she pulled out a condom and dragged a red-haired dancer into the private room. She came out disheveled but with the biggest grin on her face. "Ohmigod, that boy is incredible, he kept me humming through three separate orgasms and he never came. He about wore that condom out." The girls all laughed uproariously and so did I. Something had definitely changed over the last two weeks. I was entertaining serious thoughts of inviting a man who could make me cum three times too. Robin Gets Her Revenge Instead I still surprised myself as the girls at the table led by my sister Robin got one of the dancers to drag me on the stage, sit me down and enticed me to suck his cock. He ran a line of whipped cream down his partially erect cock and used a towel to hide what he was trying to get me to do. I could clearly hear my tablemates screaming out, "Suck it!! Suck it!! Suck it!!" So under peer pressure and also because I was so aroused at this dancer's cock bobbing a mere inch from my lips I opened my mouth and engulfed the head of his penis. I slid my lips down as far as they would go and when my mouth was three quarters of the way down, the dancer held me head in place almost choking me and let the towel fall so all my girlfriends could see me sucking this guy's cock. At that point I figured what the fuck. I slid my mouth off, turned and yelled for Robin to join me on the stage and the both of us thoroughly licked and sucked whipped cream off this guy's cock. Quite embarrassed and almost cumming in my panties I headed back to my table to wild cheers from my tablemates. As I sat down I thought, "I'm screwed. If Mark finds out about me sucking a stranger's penis and sleeping naked with Michael last night my marriage to him is done." That thought chilled my ardor and I remained quiet for the rest of the evening. Robin and the other women were loud and boisterous all around me but I just shrank back into my chair debating whether to come clean with my husband. I didn't want Alice's life of lies. That night despite these feelings of guilt I woke up in the middle of the night horny as all get out and needing to relieve myself immediately. Hearing Robin snoring slightly I pulled back my covers and began to run my right hand up and down my belly and over my breasts. I tugged at each nipple until they were both stiff. I had thoughts of Jeremy, Michael, the dancer at the strip joint and Mark dancing in my head as my fingers danced across my body. My hand trailed down my belly until I felt the stiff nub of my clitoris. I stroked my finger up and down the length of it until I felt my labia part. I then ran my finger in circular motions around the orifice of my vagina. I slide my index finger deep inside the wet warmth of my pussy until I felt the fingertip reach my g-spot. Now with my other hand I kept up a steady rhythm up and down and side to side on my stiffening clitoris. I soon had its 9,000 nerve endings screaming for release. I arched my hips up so I could push my fingers deeper into my liquid pussy and push my little finger up my anus. My back was now arched off the bed and I felt that surge of vibrating pleasure that told me I would definitely have a nice orgasm. Again as earlier, intense thoughts of taking Jeremy's penis all the way inside me pushed me over the edge. I began moaning and at first was concerned about waking Robin up, but then the pleasure was too good and I ignored any precautions of being quiet. Within seconds that incredible rush of pleasure-filled spasms contracted my anus around my little finger, contracted and opened my vagina around my other probing fingers, vibrated my clitoris, and sent waves of shudders through my belly and my butt. I cried out weakly as the pleasure grew to be too much for me to contain. The whole bed shook as my shoulders and feet shook violently and in turn shook my bed. And then I squirted. A thin powerful stream of liquid came squirting out of me past the foot of the bed. "Wow, that's fucking amazing. I have to get this." The click, click, click of the camera on Robin's phone let me know she was capturing all of my masturbating orgasm. The stream jetting out of me, my fingers still locked between my legs, my back and bottom arching off the bed, and the look of helpless ecstasy on my face as I half turned towards her and finished my several-minute-long orgasm. I was helpless to stop until the orgasm stopped. Once I finished I said, "Robin, don't do that!!" But she already had photographed me in this helpless, naked state, and what I didn't know then was she already had photographed Michael and me in bed, Michael standing there within inches of me with his semi-erect penis nearly touching my nude body, and me on the stage when I had that unnamed dancer's penis in my mouth sucking away on it. If she wanted to out me to Mark, I was fucked already. But I knew none of this. So I figured even if she had photos of me masturbating and cumming that would only prove I was a healthy, modern woman taking care of her needs and missing her husband. Like I said I had no idea at this point how far my sister wanted to go in ruining my relationship with Mark and that she had already photographed me in compromising situations. Satiated I scowled at Robin, pulled the blankets over my nude body, and drifted off to sleep. The next day while she was in the shower I pulled her memory card from the phone and replaced it with a blank one. I didn't want these photos getting shared out by my wild sister who would post almost anything on the Internet. Again what I didn't know was that she had already stored the shots on her laptop. On the fourth day, even with masturbating in the middle of the night, I woke up sexually alive and full of energy. Despite the almost constant arousal I took another pink pill. I loved what the pills were giving me. They not only heightened my libido but also my performance and my senses. For me sex seemed to be linked to my energy levels. I greeted every moment of this fourth day of the trade show as if I was experiencing it for the first time. My elation and energy was obvious to my potential customers, and I had another record day along with Robin who benefitted from the energy I was bringing and how I turned the customers on to her product line as well as mine. For our fourth evening's entertainment the Michaels, Irish Michael and Italian Michael approached Robin and me and wanted to take us out to dinner. It was to be just dinner, no dancing, and it was to thank us for the lovely time we had had together. We had a great dinner of lobster and steak and then we parted. I thought Robin and I were heading back to our room for an early night, but Robin informed me that Jeremy was here and would be performing at the very strip joint we had been at the night before. Despite my reservations about going to a place to see a man whom I found incredibly attractive in not only his looks but his equipment I joined Robin. We met up with several of our female cohorts and had a great time. During the night I left our table to relieve myself in the bathroom, not masturbating, but rather peeing from drinking so much. When I returned a new drink was at my seat even though I had not finished the former one. Robin leaned over, "Sorry, sis, I accidentally polished off your other drink. This is different but I hope you like it." I took a sip and it tasted very good. So I drank the rest over the next hour. Jeremy's set was shortly after I finished the drink and yet another was placed in front of me after Robin explained to the waiter, nearly nude mind you, what she wanted for me. As Jeremy disrobed on stage all of us women who knew him as our fellow sales representative cheered him on. He called up Alice and it was erotic as all get out to watch Alice work on Jeremy's huge penis. That she could get her mouth around so much of his penis and that she knew how to deep throat a man so her throat and mouth were like a woman's vagina had Jeremy pushing Alice away before he bathed her throat in cum. When she pulled her mouth off of his penis it was all shiny with her saliva. My goodness but it looked magnificent standing straight out from his taut belly, all shiny and erect. After his set he took Alice back into the private dance room and she looked positively radiant when she returned with a butt naked Jeremy still sporting a huge erection right behind her. We all pressed her as to whether he had fucked her with that big cock. After relentless pressure she admitted that. "No, he didn't fuck me unfortunately; he said he's saving that for someone else here in the club." We all looked around but Robin nudged me hard and the picture popped into my head of how magnificent his erect, dark brown penis had looked when he was so near to me back in Vegas. Damn, but I wanted him to fuck me. I felt immediately guilty at the thought of betraying Mark, but the erotic feelings still persisted. Alice continued, "You know, girls, his tongue is almost as long as his dick; that man just made my pussy scream with pleasure. He had his tongue in places I didn't know a man could reach like that. I don't think I'll ever see him the same way at the trade shows. When he's talking to me I'll always remember what his tongue did to me." Several of us, including me, became quiet; we were all visualizing what Jeremy's tongue could do for us and to us. I think it was shortly thereafter that many of us departed...probably to masturbate to images of Jeremy and the other dancers and how they turned us women on. Robin and I went back to our room. Robin said she was going to stay up a little while, but I stripped naked, washed up and slid in between the cool sheets of my hotel room bed. Normally I slept in a t-shirt and panties, or PJ's lately, but I had felt the need to be naked and wasn't expecting company. Despite feelings of sexual need I drifted off to sleep as Robin puttered around our room. Her activity somehow comforted me and I quickly fell asleep. I dreamed weird dreams. I had invited other men into Mark's and my bed. While I knelt between Mark and some of my husband's friends, my hands were stroking their magnificently hard, erect cocks. Soon jets of semen spurted out from the heads of their penises and I caught each arcing spurt in my mouth. Soon the amount of cum filled my mouth and slippery white cum began to drain down my chin and spatter my large rounded breasts. Drips of cum caught on my turgid nipples and encircled each nipple with a driblet of cum which made my nipples shiny. I felt fingers moving between my legs. My husband and the other men were demanding I swallow what felt like quarts of jism. Mark handed me a glass full of cum. I drank the salty, sticky fluid down. I used my fingers to scoop out some of the cum and ran its creamy substance over my own clit and pussy lips. Now I felt a pair of hands grabbing my butt firmly and kisses were raining down my back and then the sharp thrust of an incredibly hot penis as it pushed up my butt. Fingers played with me between my legs. I moaned and cried out with incredible pleasure. I was spent. All my men including my husband were spent. We were now on a sunny beach. Jeremy and Italian Michael were there. My husband was there too but he was in a beach chair watching me slowly stroke both Jeremy's and Michael's huge cocks. My hands traveled long distances from the hairy base of their cocks to the engorged tips of Michael's circumcised and Jeremy's uncircumcised penises. My right hand grew warm as I now focused on Mark's penis. He was now where Michael had been. I stroked it up and down and up and down. With all the prior scenes in my dream I had heard no noise except my own sighs and moans. Now I heard Mark groaning as my stroking had its affect. His cock got very hard and very hot. It felt amazingly hard; I wanted it up inside of me. Now he leaned into me and his fingers began to play with my own clit and pussy lips. His fingers probed up inside of me. I was very wet. Damn, but what he was doing felt so fucking good!! Mark's fingers flew fast between my legs and I quickened my pace on his penis. I leaned my face down and sucked the delicious tip of his penis into my mouth. Stroking and sucking him rapidly and more rapidly. We both came. Jets of his delicious cum shot into my mouth. My hips bucked and quivered from an intense orgasm. And I came out of my dream with a start to find my mouth indeed full of real cum and my body still quivering and bucking as fingers played with my pussy so exquisitely. I swallowed the cum to get a breath. I looked up to see Mark wonderfully nude and covered in a fine sheen of perspiration. The muscles of his chest moved so well as his fingers found their mark between my opened thighs. He was gazing at me with passion as his dark eyes devoured my naked body. His long black hair hung around his face and framed his handsome visage so perfectly. A second orgasm crashed into my clitoris with Mark's or was it Michael's incessant fingering playing my inch long clitoris like a soft silky guitar string. It was Mark but he looked like Italian Michael...dark, swarthy, beautiful long hair, triangular, well-muscled figure, dark-haired groin with a large smooth cock and heavy smooth testicles hanging between his hairy thighs. I was confused but too aroused to stop. I did not question that I was not in a dream but was actually in a bed with Mark (or was it Michael?) and we were pleasuring each other. I ran kisses up his chest to his face. I reached down and pressed his hand into my red-haired genitals as if to say "Please don't stop doing what you are doing so well." The pleasure was so intimate and so exciting. I wanted more. Behind me I heard my sister moaning loudly. I looked over my shoulder to see her face up, her hips doubled back and the other Michael fucking her so furiously that Robin was thrashing back and forth on the bed as if she were trying to escape the incredible pleasure Irish Michael was giving her at the moment. I leaned up and kissed Michael on the mouth. Ohmigod, it was Michael!!! And this was no dream. Still I let Michael's finger play inside of me faster and faster in a way Mark never had. Rapidly he worked my open pussy up and down and I felt his fingers rapidly moving inside my vagina in a way that was driving me mad. I came...violently. I screamed out my pleasure and shook madly with my hips bucking and pressing hard into those wonderful probing fingers on Michael's large hands. Once again, like the night before, I ejaculated a hard stream of fluid that splashed all over Michael's wrist and hand and wet the bed we were on. When that stream pulsed out of me it intensified and extended my orgasm. I kept quivering uncontrollably. Michael wrapped his dark arms around me and held me close. He rained kisses over my head, my face and my ears. I finally sought out his lips and our tongues entwined around each other. We kissed each other passionately but tenderly. Realizing I had betrayed my husband, even if I had been unaware of what I had been doing until it was too late; I began sobbing and then crying. "Oh god...oh god," something I had just been uttering a few moments earlier but in a far different context. "I can't believe I have betrayed him. He loves me. I want to die. OH, god, Michael, but your arms feel so good. Oh Mark, please hold me." His strong arms encircled me while I cried and his kisses touched my head. I heard him say, "Robin, this ain't right." I didn't know what he meant. He was my husband, Michael, no Mark, and he was holding me in his arms after making me cum so well. I drifted off to sleep. The next morning I awoke and had the vague sensation that I had had intense erotic dreams, even my mouth tasted funny. But all these memories were vague. Robin woke me up with a big grin on her face, "Remember last night. You were incredible." "What are you talking about, Robin? I've been in my bed all night, what do you mean? " She didn't answer, but looked disappointed. I told her then about my vivid erotic dream with Mark, Michael and Jeremy. Mark and Michael were all mixed up in my head. I told her my mouth tasted funny and it also was very dry. I got up and got ready, feeling quite wonderful. This seemed to disappoint Robin which was curious to me. She reminded me to take the last heart-shaped pill. We had only one more day to go and then back home to my family. I popped the tablet and about an hour later felt a surge of energy but also felt my libido rise. Every man looked good to me this day. I flirted practically with every customer we talked to. Every man looked delicious and I found it difficult to make sales because all I could think about was what he looked like naked. I even began to wonder about some of the women we spoke to. Robin remarked to me that she was finding me quite funny, but she said I should keep it up. My flirting was making us oodles of money even from our female customers. At the end of the day Robin was ready to party and frankly so was I. We had had a remarkable day and week in sales and I had been so horny all day that I needed to blow off steam. I had not had the opportunity to return to our room and masturbate in order to relieve myself. I suggested we go back to the strip joint. Robin got several of our girlfriends together and we headed out to the strip club. This time I hadn't called or texted Mark. I don't know why; I just didn't. It was while we were getting ready to head out that Robin handed me a glass of cold but cloudy water and told me to drink it. She also handed me another pink tablet. An hour later at the club I was so aroused that my pussy was gushing. It was all I could do to keep from fingering my own self. I wanted my husband bad and I headed to the rest room and called him, but only got his voice mail. "I miss you Mark and wish you were here. Can't wait until tomorrow when I can see you and the kids." I know I must have sounded pathetic and lonely, but it was the fire raging in my crotch more than anything that made me want to see and hold Mark so badly. When I returned to the table it wasn't long before I felt a little confused. The dancers began to look like Mark. This warmed me up to their performances. What was Mark doing here stripping for all these screaming, raucous women? My goodness but he looked good with his cock, bigger than I remembered it, all exposed and hard. Women were touching him and I found this arousing. My husband was up on stage and he was the entertainment for all these women. When I told Robin this she laughed and said, "If Mark is up on stage, why aren't you up there too, Sis?" A man passed by our table and I took his hand and he led me up to the stage. My girlfriends and Robin were cheering me on. He danced around me on stage. Was it Mark? He was slender, had brown hair and blue eyes like Mark, smiled like Mark, and when he ripped off his g-string his cock looked like Mark's with a natural patch of brown, curly pubic hair covering his groin and his testicles. When he offered his cock to my lips I tasted the tip at first with my tongue, then I licked his hot penis with my tongue. His cock tasted salty, but his skin was smooth and silky. I liked running my tongue up and down his cock. Here was Mark on the stage and we were having so much fun in front of my girlfriends and the other women in this club. Mark pushed the tip of his cock past my lips and I slid my mouth over him. A little of his salty cum leaked out onto my tongue and I swallowed it. He caressed my face, my head and my neck with his strong hands. I grabbed the shaft of his cock; gosh, but he seemed bigger than usual. Maybe it was dancing in front of all these women that had made him larger than usual. I stroked his cock up and down, feeling the soft silky skin of his penis slide up and down in my hand. I slid my lips down as far as I could and my nose was in the thick curls of his dark pubic hair. His manly scent was very pleasant to smell. I took my mouth off of his penis and kissed the hair and skin on his groin and his hips. I tilted my head up and told Mark, "Please cum in my mouth baby. I want you." I returned my lips to sucking and licking his penis. Mark began thrusting his hips back and forth in and out of my mouth. I watched as the muscles of his belly tightened and relaxed. With my hands I grabbed his muscled butt cheeks and guided him in and out of my mouth. I felt his butt tighten, heard Mark groan and then jet after jet of hot, salty, sticky semen coated the back of my throat and filled my mouth with delicious cum. I leaned up after he had finished spurting and swallowing the creamy load in my mouth I stood up and kissed Mark right there on the stage. "Thanks, baby, I needed that."
