I was, naturally, quite shocked to see a real-life fairy. A state further enhanced by the fact she had misunderstood my wish. While I did want to be loved by lot of peoples, I wasn't speaking romantically. (Although I must admit that I hoped it would include me finding a girlfriend.)
Once the shock passed, I first thought it wouldn't change much in my future girlfriends beside their feelings for me, outside being a bit healthier for some of them. You see, I'm the kind of guy who think there is more than one form of beauty. Some women are cuter with small breasts, some, are better with big ones, and some need to be a little plump. In fact, as long as they aren't obese, skinny to the point you see their ribs or bodybuilded to the point of looking like a vaguely human-shaped mass of muscles (which is almost as unhealthy as the two previous cases), then it IS a girl I can love.
So, she can be any body-shape as long as it's not an exaggerated one, (which, again, is unhealthy) I don't care about the color of their skins and, as long as they're nice, they would be women I could love. So, it would only change them for the best, right?
Except that, thinking on it more, I realized I had a thing for succubi. How often did I fantasm about a succubus that, instead of searching to drain all life out of me, fell in love with me and searched (and found) a way to feed on me without endangering my life? And part of this fantasm had that succubus willing to share me with other succubi, as long as they could guaranty it wouldn't have an harmful effect on me. Not only that, but she would also turn anyone wanting to end my romance with her (or any member of my hypothetic harem) into one of them, making that opponent into one more succubus lover.
And each and every of those succubi would have breasts full of milk (yes, even the flat-chested ones) without changing the size of said breasts, nor ever leaking while no one was sucking on the breast containing it. A extremely nutritious milk that, if given to me could not only replace all my meals, as long as I drank it 3 times a day minimum, but also increase my stamina and vitality so I could always feed my forever expending harem.
Of course, said milk would also feed the daughter we would inevitably get. Daughter that, even if I am human, would be 100% succubi, like their mother.
So, all the future members of my inevitable harem will turn into succubi… Crap.
