Ohmigod!! What Jeremy was doing felt so good; how could that be so wrong? 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.
