if its root cause is science based, this would be the proper category, however, know that if it turns into a "cum vamp" type story with more focus on the vamp and no "sciency" stuff instead, it would be better fit for the nonhuman category
that all being said, it was rather hot, but SHORT and RUSHED, other then that, if you take the time to develop your story more, detail the sexual scenes and even some inbetween (and yes, that sexual scene was god awful dismul compared to what I think you could have done with it), then you have the making of being both a great author AND a great story!
Very good, is there more? Well written and thought out, this could turn into a very interesting idea
