Growing up in a large family made me close to several of my brothers but not very close to my sister. In fact we didn’t get along very well at all. As an adult I found her opinionated and argumentative. In short I didn’t care to be around her that much. In spite of this my wife and I ended up living in the same neighborhood as my sister Kathy. She and my wife worked as flight attendants for the same airline and were usually gone 3 or 4 days a week. After my sister took this job I began to hear rumors about her. There were stories coming from different people that she apparently used the time away from home to have some extramarital sex. At first I discounted the tales as just talk but they persisted and even got wilder as time went on. My wife had even seen her pick up guys, both black and white, in bars while on overnights and take them to her room. I even heard stories about her giving head to guys on the airplane. My sister had become quite the little slut.
This went on for a couple of years and my sister became pregnant with her first child. The pregnancy went well and all seemed to be going ok for she and her husband. Several months after the birth I went to see her and the child. During the visit she sat on the sofa in just a robe and breast fed her child. At one point the child let go of her nipple and it was suddenly exposed to my view. Now my sister is a very attractive woman with blonde hair and blue eyes and even before the pregnancy she had very large breasts and a well rounded firm ass. Quite a looker and now with her breast feeding her breasts were simply huge. I had seen many a tit before but never had I seen a nipple like this one. It must have been 3 inches across at the base and sticking straight out at least a half inch with milk squirting out of it. It was something to see and I caught myself staring at it.
Kathy noticed my interest and said, “what’s the matter, you never seen a nipple before?”
I responded, ”never one like that”.
She laughed and said. “ I wish my husband would look at me like that again.” I asked her if they were having problems and she said, “never mind, it’s nothing for you to worry about.”
I was curious and managed to bring the subject up again several months later, shortly after she had returned to work. I was at her house helping her move a piece of furniture and asked how are things going now since the baby. She got us both a glass of wine and confided to me that she and Steve had not had sex since the pregnancy. She went on to say this was causing a problem and she was having to get sex elsewhere. I didn’t let on that I knew about her promiscuosness and tried to be a good listener for her. She said she had tried different approaches to get Steve interested again, including role playing, dressing up as a prostitute and so forth but nothing seemed to work. My mind raced at the thought of her dressed up in heels and stockings and looking and acting like a whore. I felt my cock begin to rise in my pants. I asked what types of things she had worn for him, suggesting maybe they were not hot enough to interest him.
With that she jumped up and said “wait here and I’ll show you.” The time seemed to stand still but after a while she reappeared with an outfit on that was unbelievable. A black lace teddy that didn’t cover up much of her tits except for the nipples, black garter belt, sheer tan stockings and black high heels. “So what do you think, should this have excited him?”
I blurted out “you look like a whore.”
She said “well yeah, that’s kinda the idea.”
I then told her that I had known for some time about her fooling around while on the road and that I was surprised by her behavior. I think this shocked and hurt her because she took a seat beside me on the couch and began to cry. I felt sorry for her. Between the tears she said she only started doing it because she wasn’t getting any sexual gratification at home but that later she continued with it because she enjoyed it so much.
She seemed ashamed and embarrassed. I put my arm around her to comfort her and told her “it’s all right, everybody loves to fuck, we just don’t get to do it like you do.” She looked up at me with those beautiful blue eyes full of tears and kissed me full on the lips. I was taken back for just a moment but instinctively returned the kiss in similar fashion. Soon we were locked in a loving embrace kissing each other like two teenagers on a first date. This went on for a few minutes and I soon found myself lying on my back on the couch with her on top of me kissing me like I’ve never been kissed before. I realized the situation was bizarre. I was making out with my sister, she was kissing me with the same lips she had used to go down on and satisfy all those guys on her trips. It was strangely erotic and I began to enjoy it.
My hands found their way down her torso sliding over the top of her garter belt and to the stockings on her legs. They were silky and warm and felt so sexy. I took the opportunity to run my hands over them for a few minutes while we kissed and slowly let them rise to her hips and up the straps of her garter belt to her ass cheeks. They were nice and firm and round and for the first time I was able to touch them, not just look at them from a distance through clothing. She was now beginning to thrust her hips against me in a rhythm.
She raised up and supported herself on her hands for a moment and asked “are you ok with this, if not we’ll stop and never speak of it again?”
I said “ I never really planned on this happening but must admit I’m really enjoying it so far and you are quite a beautiful woman.”
She got a huge smile on her face and lowered her face to mine again. It seemed very loving and not wrong at all. By now my cock was swollen to it’s full 7 inches and I’m sure she could feel the outline of it through my jeans. She seemed to center her thrusts against the bulge in my jeans. It felt good and I wanted it to continue.
After a few more minutes of this she again raised up and said’ “I know you like looking at my tits, I’ve seen you checking them out several times but I didn’t want to embarrass you. Would you like to see them?”
“Of course I would, “ I said
“Good, I’m very proud of them and love to show them to men who appreciate them,” and with that she pulled her teddy down freeing her breasts and giving me a full look at them with their swolen nipples. I brought my hands up to them and gently and lovingly began touching and squeezing them while she just sat there on my crotch with a smile. She still had milk from the breast feeding and soon the tips of her nipples were getting wet with breast milk.
I asked “ are you still breast feeding?”
