Cute. Nicely done!
I have to admit that I'm with dennisud on Hermione and Luna. Oh well. ;-)
I don't see anything wrong with Ginny, personally--she's only a year younger than Harry, for God's sake, and he's being careful with her.
I don't particularly think you've made whores of Katie, Angelina, and Alicia, either, FWIW.
Author's response
I'm trying to keep Harry's relationship with Hermione and Luna more in tune with Canon. I never planned on him having a sexual relationship with Hermione.
Harry's relationship with Ginny will become more complicated in future stories.
Katie, Angie and Alicia are normal, horny teenage witches, as far as I'm concerned. They certainly don't think of themselves as whores.
Thanks for the review and I hope you'll enjoy the next part when I get it posted.
