Harry's head tingled pleasantly, like delict little fingers tickling and massaging his scalp before shooting outwards, waves of long dark red and black wavy hair cascading over his shoulders like a waterfall. The luscious forest of thick, silky hair continued to grow till it reached the back of his caves. Full dark red and black tresses now framed Harry's face. A pleasurable warmth arose suddenly in intensity from Harry's privates, rising from the core of his inner being outward before quickly reversing. Then continuing inwards, the warmth spread and expanded, as it went, Harry now Rose felt her ass expand. It grew larger, softer, firmer, heart shaped and round to perfection. She cupped it, one cheek in each hand and gave them a squeeze. Very firm but with just enough cushion that Rose could sit on a hard stone floor and still be just as comfortable sitting on a feather pillow. Despite being new to her gender she was proud of how full and pert her sumptuous new ass was.
The teasing, tingling sensation rose, circling around her belly button and stomach. Pain flared across Rose's face, as an invisible corset pulled tight. Her waist shrinking ten whole inches. Her stomach became taught and firm with well defined muscle that would be clearly seen without clothes on. Her hips popped out wards making her now hourglass curves even more obvious and rich.
Meanwhile the warm magic flowed down into Rose's legs. The magic shaped, sculpted and lengthened her legs till they were long and curvaceous. The magic gave her legs gave her just the right amount of muscle to make sure they powerful and well built, but still soft and creamy enough to make silk feel like sandpaper. The magic also gave her cute, dainty feet with perfectly trimmed and polished toe-nails.
The tickling warmth then turned northward. Her hands were soon as soft as the rest of her body and grew slimmer with longer more delicate looking fingers topped with magnificent nails, each painted in a perfect glossy coat of crimson. Rose's arms were just as slim, soft and strong as her legs.
Rose lifted her hands to her chest as the warmth spread into that spot. She didn't have long to wait, as the tickling built behind each nipple. Each nipple swelling as she watched, the areola spreading wider and wider. The nipple rose, swelling and pushing far beyond what Rose had ever imagined possible. It was erect, and felt like it was thrusting forward an inch and a half and was as thick around as her thumb.
As if in envy, she felt the magic spreading wider, and deeper. Soon the proud nip was atop a surge mound of abundant flesh. She wasn't used to estimating a girl's size, especially from this angle. But the weight growing in her outstretched palms suggested she was quite exceptional. As the spell continued, so did her expansion. A jolt of fear shot through her veins, as she hit E-cup then blew past it! The girls were beyond what Harry had ever wanted. Even Rose was a little nervous about being so busty. At last the growth slowed down till it stopped at an outstanding H-cup.t The breasts were very round, almost no sag, firm, and stuck=out from her body in just the right way to achieve maximum attractiveness.
Finally satisfied, the magic raced upwards. She felt her face twist and shift. Cracks coming, as bones broke and adjusted. Looking at her body, she was oddly calm. With such an incredible body, she knew her face would be equally spectacular.
Looking in a mirror, she saw a radiant, regal young woman with creamy white skin, full, plump velvety, soft pouting lips. A tiny mouth, that even without doing anything seemed happy and royal in quality and only needed a smile or laugh to be complete. Her cheek bones were high and perfect. Her eyes, still like her mother were like emeralds, hinting at a feline nature She had sophisticated high-arched brows. She had a cute nose that combined with her glasses gave her a look that was adorable but spoke of a high intellect and inner strength.
As she posed in front of the mirror, she watched as the Hogwarts uniform rippled into existence. The blouse just a size too tight, gapped as it fought to cover her chest. Beneath the blouse, a rather sturdy bra was weaving itself out of fresh air and the finest satin. She felt the soft cups cradle and support them. A mini-skirt was also appearing from nowhere, the simple cotton pleated item almost disappointing in it's plainness. Until Harriet saw just how short it was. It barely reached below the curve of her ass. Even the slightest breeze, or bending over would flash her arse. If the school hadn't been all-girl, the boys would be walking around with permanent erections.
She flattened the skirt, giving a daring half-twirl as she watched it lift. A soft, feminine, girly gasp burst from her lips. The final part of her uniform was forming. She felt the slenderest thread of a thong slip between her cheeks. It dug deep, feeling like soft piano-wire, as the front joined the back.
A deep sense of self-worth and pride in her apparent power and appearance made her take a deep breath, and hold it proudly. In the mirror, she never looked more perfect. In fact! She looked like with a little training she could take down the Dark Lord right then! If there was ever an embodiment of a powerful Noble Lady of magic she was now it!
