I grew up in a fairly large family. I had two sisters one 8 years older and one 4 years younger. Later when my parents got divorced and then remarried I found myself with 4 step sisters. These were girls that I had grown up with, played hide and seek in the closet with 2 of them. One was 1 year older, the others were 1 year, 4years and 8 years younger. When my oldest sister got married, then divorced, then re-married, then re-divorced, she ended up with her family that I kind of looked after when she wanted a night out on the town. I was the good uncle and didn’t really think much of fucking anyone in my family except for 3 of my 4 step sisters. Now my older sister was hot! My God, she had a body and such a beautiful face. She also liked to party and perhaps that is why all the divorces so early in life. 

So there I was, looking after her three kids, 2 boys and my adorable little niece! That night she came home quite drunk or stoned, and I still don't know what really happened. I remember we were sitting at her kitchen table drinking coffee, I was trying to sober her up before I left for home, and my nephew came in and she started to talk with him asking about his day, what he did at school and trying her best not to slur her words! 

He was young at the time and should have been in bed, but he came down stairs to ask her about something that he had heard at school! He said, "Mom, what’s a cocksucker?" My sister kind of gasped, and said, where did you hear that word? He told her that a kid at school had called him that and he didn’t know what it meant… so what is a cocksucker? 

She looked at me as if to ask for help and I remember shrugging my shoulders as if to say, keep me out of this. She looked at her son, and said matter-of-factly, “a cocksucker is someone who puts a boy or man's penis in their mouth and sucks on it.” My nephew said something like, Euuuu gross and went back to bed, satisfied with the answer I guess! 

After he had gone, she was still quite wasted, not sure if it was booze or pot or pills, but she asked me what I thought of her answer. I told her it was quite to the point and, yes, that was answering exactly what he asked her. She said what did he ask me? I told her, you know… that question, the one that he just asked you! 

She started to laugh at me and said, you can’t even say it can you? I told her that I could but… didn’t want to! I was getting a little bit embarrassed right about them, and got up to leave. She said, sit down, stay with me for a while, she said she was sorry and wouldn’t embarrass me anymore. I sat back down and she said, alright, you know WHAT a cocksucker is, do you know WHO a cocksucker is? I didn’t understand what she had just said, so she repeated it to me again looking directly into my eyes! Do you know WHO a cocksucker is? Except for some of the girls at our school who had the reputation, I really didn’t know and was beginning to feel like a bit of a dork! 

She said, “I AM A COCKSUCKER! I SUCK COCKS” and then she said, “when you were really, really, young, I used to suck on your cock” What? She said, "When you were 3 or 4 years old, I used to suck on your cock, you must remember! You wanted to see my “muscles” that’s what you called my tits so I would take off my top, take off my bra, show you my tits, and suck your cock! Her words were slurred and she was telling me this as if she was saying that the weather sure is nice today isn’t it. 

I was 16 at the time, just got my first car, and had an erection listening to my big sister tell me all of this! My cock was just about on overload and it was beginning to hurt.

I told her she was full of shit and she said, I’ll bet I can prove it. Bull shit! Prove it, my fucking heart was racing, my breathing was getting shallow and I had a hard time not looking at her lips imagining them around my cock! But you can’t fuck your sister… right? It’s not natural, It’s perverted… it’s so nasty! She shouldn’t suck your cock should she? She couldn’t have done it when I was younger, I would have remembered that! That is something that you would never forget! Right? 

There she was, still slurring her words, and she began to touch my chest as she sat next to me. I told her to cut it out... she said what, don't you like me touching you? I had dreamed about and read about adventures like this and imagined scenarios like this from the time I was eight, but right now I was kind of freaking out. I didn't know what to do or what more to say, besides cut it out, stop touching me.

She took her hands away from my chest grabbed onto my hands and put them on her chest saying now we are even, do you remember touching my muscles? She took my right hand and put it under her skirt just looking at me straight in the eyes. I felt her panties and they were wet and she started to grind her cunt into my fingers. Her breathing was fast and I was still FREAKING OUT. My cock was rock hard at that time, didn't know how long I could keep from cumming. I really didn't want to cum in my pants in front of my sister, but there I was and there it was, fully orbed and fully alive! After a few moments of rubbing her cunt all over my hand, she then said, “Now you are one up on me and then put her hand on my cock as if this wasn't her brother but some guy she picked up in the bar!

I thought fuck this, if she wants to act like a slut, I will treat here like a slut! l said, “take it out”, she said no, “you take it out,” so I unzipped, pulled my cock out right in front of her face, grabbed her by the side of her head and put my cock right on her lips. She pulled back, looked at me right in the eyes and said, I want you to cum in my mouth." She opened her mouth and began to suck me off. I lasted less than a minute the first time, but what minute it was. I can still remember what she was wearing, how she smelled, and how she moaned as she began to suck me off! I still get hard thinking about that.

The next time I went over to her house to look after her kids, it was late and I was down in her rumpus room watching television. I heard her come in and she was talking with her girl friend and I know she was either drunk or stoned so I left the television on, undid my zipper took my cock out of my pants so it would be in plain view and pretended to be asleep. I was so scared but all I could remember was her sucking my cock the last time. She came downstairs and I heard her getting closer and closer and I am sure she could hear my heart beating it was so loud, but I didn’t move, my cock was rock hard then then I felt her fingers touching my cock, hand stoking it very gently and very slowly, and I couldn’t open my eyes to see what she was doing but I am absolutely sure she was looking right into my eyes. Then I felt her breath than a lick of my cock getting some of the teenage precum and then the warmth of her mouth around my cock, then I heard her say, “You aren’t asleep are you?” and I immediately came in her mouth and she swallowed my cum. Her friend was watching from the doorway and I was embarrassed (me embarrassed, it should have been my sister but her friend kept licking her lips every time I saw her until I put a stop to that. But that’s another story.

ps My sister and I kept seeing each other, fucking, sucking and she is the one who taught me how to eat pussy!
