Hermione Granger

Luna walks down the corridors thinking about her new target

she walks around the corridor and finds the person she is looking for Hermione Granger but she isn't alone.

Hermione is standing talking to the large breasted Hufflepuff Susan Bones.

Luna thinks about this and realizes she could use Susan for a test.

Luna peaks around he corner and fires the spell at Hermione

''Hermaphrodie'' Luna whispers

she sees's the spell hit Hermione and sees her look down at herself then tells Susan something and they both run down the corridor which Luna follows. she reaches them and finds them in the girls toilet on the second floor. Luna enters and hears Susan's voice.

''Hermione are you ok''

''No something happened to me and i don't know what''

''what happened''

Luna see's the stall door open revealing Hermione now with a 12 inch cock hanging between her legs with two large testicles the size of footballs

''Merlin'' Susan says now seeing what is between Hermione's legs

unknown to both of them the sent that Hermione's dick is giving off is slowly making Hermione look at Susan in a different way. Hermione now staring at Susan's breasts feels her new cock get an erection sticking up pulling her skirt up making her testicles more revealing.

Susan see's this and slowly backs up. Luna knowing what Susan is about to do locks the door and disperse it so that no one can enter from the other side as well. she then cast's a notice me not charm on herself and sits and watches.

Susan seeing Hermione walks over to her sprints off to the door but see's that it's gone. she turns around and see's Hermione right in-front of her face and slam's her into the wall and presses her lips Susan's and shoves her now much stronger tongue into her mouth and starts to group her chest. after a while Hermione get's fed up and let's go, Susan thinking it's finally over looks up at Hermione and see's that she is stroking her very erect cock staring down at her. Luna quietly casts a spell on Susan causing her uniform it shred it's self so that it can't be used again. Susan looks down at her now naked body at the same time Hermione does but unlike Hermione who doesn't care how it happened she try to cover herself to protect her dignity as much as possible. Hermione looks down at the now naked girl and pull's her up and pulls her to the sinks and places her at it see her ass is raised and facing her
