the virus of lower inhibition

[Guest Draynuy]

At the end of his third year, during his mission to save Sirius, Harry and his two best friends, the twins Ginny and Rose Weasley, are sprayed by the pollen of a unique plant that only grows for one night of full moon every two hundred years.

Unknown of the teens, the pollen of this plant acts like a virus that slowly lower the inhibitions, particularly the sexual inhibitions, of the magical beings infected, furthermore the victims produce themselves the pollen/virus who is transmitted by airborne way, oral way and sexually.

Some days later, the teens are going home, without knowing that the "illness" will quietly incubate in them, since their family and close relations will simply attribute their changes of comportement to the adolescence.

While that Rose and Ginny go back to the burrow where they will slowly and unconsciously infect their family and some friends, Harry returns toward the only member of his family that he love, his little cousin of nearly 12 years (born a 21 september), Dahlia. To his good surprise, and the bad one of the rest of his family, he learn that Dahlia is in fact a witch who will begin this first september. Dahlia being now as welcome as Harry himself, she stays really close of her cousin which results in a more quick infection than normal (Petunia is also infected but it will only become apparent after the summer), she also goes with him when he goes to the Weasley for the world cup.

After the summer everyone returns to Hogwarts, who, with the virus and the presence of three full school for the Triwizard tournament, will transform itself into a school of sex, magic and sexual sorcery. This year will mark the beginning of a change in the magical world.

Other detail:

Rose is a the perfect mix between Ron and Hermione who don't exist in this universe (or at least Ron doesn't).

To give a idea of the progression of the virus: when Fleur calls Harry a little boy, Harry goes immediately to kiss her, rubbing discreetly his erection to her thigh and asking, by murmuring into her ear if, now, she still thinks he is a "little" boy and that, if she has still some doubts, he will be glad to destroy them.

Gabrielle is Twelfe.

The first sex scene must be during the travel toward Hogwarts when Harry, Ginny, Rose and Dahlia fuck during all the duration of the journey. It happens only because Harry, Ginny and Rose were already attracted to each others and because Dahlia was attracted to Harry and after she goes simply with the flow.

Harry compose himself a Harme composed of Dahlia, Ginny, Rose, Katie, Daphné, Astoria, Tracey, Fleur, Gabrielle, Susan and Luna.

Optional but appreciated: the virus also acts as a mutagen that acts in function of the sexual interactions and transforms the victims into hybrid between Human and animal (both magic and common) (succubus and incubus are authorized). If you take this option Harry must transform into a half dragon (inspired from the half dragon form from breath of fire 4).
