AN: From interactive "Fanfiction Gender Change", chapter originally written by Mr.George
Luna's wandering took her to the Grand Hall. She was a little startled to see how full the room was. A quick glance at her watch told her it was dinner time.
She went over the spell in her mind. It would transform Harry into Romilda Vane, the changes would need to be slow to avoid causing Harry any pain or discomfort. However, he ... well, everybody (else) ... would be oblivious to the transformation until it was complete and Harry was alone. It was meant to be a learning experience, and not a punishment.
A smirk crossed her face, as she thought of Romilda, she was blossoming into womanhood. Luna wondered how Harry would take the attention, he was used to being stared at. But the cause of the staring would be very different.
Seating herself at the Ravenclaw table, the girls on either side, slid just a little further away. She was used to this, but it was still hard to take. As a large dish appeared before her, piled high with her favourite foods. Luna drew her wand beneath the table. Looking around, she spotted Harry, and favoured him with a smile. The spell would give the target the appropriate clothes, Romilda was known for her racy taste, and almost persuaded Luna to choose another to be the template. She certainly didn't expect Harry to be flashing her underwear, so decide to go ahead.
Harry was too busy talking to Ron and Hermione to notice. Casting the spell beneath her breath, she gave the swish and flick. A brief flash of light lit up her blouse, and she watched as at the same moment, Harry shifted uncomfortably in his seat.
The spell started slowly, accelerating as the changes occurred. Although Harry wasn't able to see the difference, his comfy boxers had just become a silken thong. A silken thong that split his cheeks uncomfortably.
An airy smile came to Luna, it was always rewarding when a spell was well cast. Tucking her wand away, she directed her attention to the food in front of her.
