My sister and I are one year apart. My mother was quite old when I was born, she was 41 and my father was 61 at the time. My mother taught Fabrics at the local college and my father was an Electrical Engineer. I spent a whole lot of time alone. I started masturbating at 14. Serious masturbating, like very night. No one said anything. All of a sudden a towel was under my sheet and the mattress. I would leave my wet and dirty underwear on the floor, my sister who is older by one year picked them up and washed them. She also washed the sheets every day. She never said anything. Her duties included the laundry at our house.

One Saturday morning I didn't get up on time because I was in bed masturbating. My sister came up to get me and she stood in the door until I was done. I hadn't heard her. She came over to me after I was done, helped me stand up and she pulled my wet underwear off. I was standing there naked with my still wet penis and she picked up my undershirt off the floor and she wiped my penis clean and sent me to get a shower. When I came out the bed was made and the sheets had been changed.

She started to come over to my room, she would get under me and let me masturbate on her while she held me between her legs. I would empty everything out on her stomach. She would clean me up, make sure that the sheets were dry, if not she would lay a small towel over the wet spot. She would make sure my penis was in my underpants and she would kiss me on the cheek and then go to her room and go to bed.

One of those nights, after I had done my thing on her stomach, she used her finger to lap up the cum and she ate it. We were fourteen and fifteen. She loved keeping my penis clean, loved having me cum all over her, she started to masturbate by having me rub her clit with my hand, or wear thin panties and have me masturbate by rubbing myself against her while she played with her clit. She would clean up all the cum with her finger, off her stomach, off of me, off my penis, she didn't want to waste any of it. I stopped having wet underwear or wet sheets and she started to have wet panties.

I was seventeen when she came over and used her hand to jack me off. By then she had become very adept at it, she could jack me off and would eat the cum. There was almost never an accident to clean up. But that day after she got me hard, she straddled me and rode down on my penis until it was deep inside of her. She rode up and down, holding on to my neck. She pulled herself up and would examine my penis, hold on with one arm, and use her other hand to rub my penis against her clit, then stuff it back inside and ride again. When I came, she hugged on tight and just let me come inside of her. She told me not to worry, now that she was eighteen she had been able to get on the pill down at the public heath clinic.

It was a good while before she laid out on her back and had me fuck her that way. She complained, she said that was her bad luck that she was the girl, the guys always got to fuck and the girls had to take it. But it was her bad luck, not mine, so she wanted me to fuck her, so I did. She still jacked me off, she liked to get a mouthful of cum.

My father died before either one of us got serious enough to contemplate marriage. On my wedding day, I got married before she did, she jacked me off so that I would last longer on my wedding night. She was in our apartment a whole lot, my wife complained that we were still tied together, why couldn't she have her life and let us have ours. My sister finally met a guy to marry when she was 30. It didn't stop her from spending most of her free time with us.

To this day she jacks me off, she says she doesn't like to jack off her husband, it doesn't feel right, and she won't eat his cum, only mine. She gets me to go off with her on some made up errand so that we can fuck. We fuck several times a month. She is pretty good at straddling me and stuffing herself with my penis and playing with her clit. She says that she only has missionary with her husband, she wants him to get on and get off. My wife still complains, why do I have to spend so much time with my sister? She and I have sex, but like my sister's husband, my wife is primarily missionary and my wife does not jack me off or blow me, which she is ok with, she thinks its gross.

Maybe our mother could explain why, maybe because she never raised us, my sister raised me even if she was really only one year older than me. And she raised me right.
