My sister Jean and I are best friends. She is seven years older than me, but we are as close as sisters could get. When I was 14 I started to develop and got interested in boys. I asked Jean to teach me about boys. It excited her to teach me.

First she said a man is really only interested in a few things. She said they like big nipples, they like a girl who will suck their cock, and they like to be complimented. My breasts were starting to develop nicely, but she said I needed to make my nipples bigger. Several times a week she would come over to our house and we would spend time in my bedroom. She had me to remove my top, and for the next two months she pulled, tweaked and rolled my nipples until they were almost too sore to touch. But it worked. I could actually tell the difference. She said I had to masturbate a lot to figure out exactly what I liked. It turned out that she was the one with her fingers in my pussy most of the time. She also taught me how to kiss. Within a few more weeks she said I really needed to learn how to eat pussy as much as sucking cock.

She showed me how to shave my pussy like hers, and after a time or two of her licking me to orgasm she had me work on her. She said I was a natural. I quickly learned to love licking her pussy as well as having her lick mine. Finally she said it was time to learn how to suck cock. She gave me a large rubber cock and had me watch hooker porn. I couldn't quite deep throat it, but I felt I did pretty good.

When I turned 15 she said it was time to suck a real cock. Her boyfriend was a bouncer at a bar. He had large muscles, and she said he had a big cock. She arranged it, told our parents she was taking me to a movie that Friday night. We went over to his place. He seemed pretty excited too. As soon as we walked in she said to remove his pants. I struggled a little, but was able to pull his pants down, and when I pulled his shorts down his cock popped out. I eagerly put my mouth around it and did like the whores in the movies. It wasn't five minutes and he said he was gonna cum. Jean had prepared me by constantly telling me how much she loved the taste of his cumm. I looked forward to it and when he started cumming I started swallowing. Instantly I loved it. It almost made me cumm.

She told me to keep sucking and make him cumm again. While I sucked him she managed to pull my pants and panties off. She laid down on her back started to eat me. I came three times by the time he came again. That was the start.

I'm now 42 and retired. I have enough money to last two lifetimes, and it was all from sucking, fucking and licking anything that would pay me. I had several steady men, and even a few married women that I managed to make them cumm harder than their husbands ever could. I became suck a fucking slut I didn't care what they looked like, how smelly their cocks or cunts were, or even how big their cocks were. Jean was right. They all loved my big nipples, they loved the way I sucked or licked them to orgasm, and when I told a man that he had a perfect cock I always got an extra tip when I was done.

I still love to suck cock and swallow cumm, but now I only do it to someone I care about and don't worry a bit if they pay me or not. What a fucking life, eh?
