My strange little food fetish

Years ago, there was a guy I really fancied, but who wasn't interested in me. I used to fantasise about him going down on me, and how it'd feel.

One time, we did a charity hike together and I offered to provide food. The morning of the hike, I got really turned on about spending time with him and I used a cucumber to bring myself off. Then I had a wicked thought and used the cucumber in the sandwiches I made for us. When he ate them, I got so incredibly turned on that he was eating my juices. I never got chance to make food for him again and I don't see him any more.

However, the fetish remained. Nothing turns me on as much, and I almost need that wicked feeling it gives me. For the past two years, whenever I've cooked for my father and brother, I've previously had many of the vegetables inside me when I orgasm. I have no real sexual feelings towards my family, but the thought of them having my juices in their mouth makes me so horny. One time my brother said the food was delicious and I felt a shiver of pleasure between my lady bits and my stomach.

I'm not doing them any harm and they don't know I'm doing it. It's just for me. But am I wrong in doing this? Also, should I tell them what I've been doing? Do you think they'd let me carry on doing it? What would you do if your sister or daughter admitted to something like this? I'm just trying to judge what is the best thing to do now.
