AN: From interactive "Harry Potter Transformations", chapter originally written by Mr.George
Ronda was panting heavily as she adjusted to her new sex. "What will this wand do... if I don't even chant an spell or incantation. To illustrate her point, she tapped herself on the tip of her delicate nose.
Ronda's luck wasn't for changing, as her clothes transformed first into the girls uniform. Her manicured and painted fingers fighting against the hem of her skirt as it rose relentlessly, Ronda turned a brighter crimson.
In desperation, she tapped herself on the nose another dozen times or so. But nothing removed or reduced her abundantly feminine body. As Harry wrestled with the idea and risk of just snatching the wand, Ron's hair started to cascade wildly from her head.
As if possessed, she purred to Harry, "Come On... This is fun."
Harry tried another tack, "Just think how your brothers will react to you now. They'll protect you and coddle you, stop you having any fun... any freedom. And do you think Ginny wants a big sister."
Ronda was still enjoying this rather too much, "A big sister." she purred back, pressing her breasts into a more visible cleavage. As Harry blushed, she put a calming hand on his shoulder.
