The One I Belong To

I'll cut the story short: I'm a woman, raised by a single mom who always taught me to keep an open mind, experience new things but always on my terms. I think she meant well and didn't expect me to orient that way of thinking and doing things towards my precociousness. I was very well developed from a very young age, and that caught the attention of men. I lost my virginity at 12 to a guy in high school.
Suffice to say that, by 15, I was actually rather experienced, and if I liked a guy I went to get him, regardless of anything. Not even if we were related.
I noticed how my older cousind looked at me, and I didn't blame him. I didn't blame myself either. He was the strong macho type that I've always liked: tall muscular, very secure and aggressive in how he conducted himself. So the moment I had a chance, I seduced him. Wasn't difficult, since he wanted it. Not long after, he gave me the first body-shattering orgasm of my life. The first of many. That experience, at 15, can get anyone hooked (let's not go into details, but he was... older).
We've been lovers since. We're in an open (and obviously secret for most) relationship, so he dates and fucks as much as he likes, and I do as well. But he's the best of my lovers by far, and I'm hooked to him. I fall into the cliché of liking long, thick cocks and very dominating men in bed. He's the one: I'm very imposing to most men, but he throws me around in bed like a bull fucking a bitch. I'm 33 now, so he's now a very mature man and he hasn't lost an ounce of his appeal. My body belongs to him.
