Lavender sighed. She walked steadily alongside Ron, arm-in-arm, gazing around at the courtyard. She'd been going out with him for a good while now and, well, she was a bit disappointed. Ronald seemed to have more interest in Harry than in her, and that concerned her. She had no problem with Harry, really.. but lately, she was beginning to wonder about Ron.


She'd tried a few times to pull Ron into a broom closet, to do more than just snog. But upon discovering what they were doing, Ron would freeze up, blush and hurry off, saying he had a mountain of homework to catch up on.


What if he's really only into boys? Lavender had asked herself this many times. But, she thought it wrong. He also seemed taken with Hermione Granger when he wasn't locking lips with herself. So, what could she do? Only one thing. She had a large, brown package sitting beneath some spare robes in her trunk in the dormitory, and had been contemplating using it. It seemed as though she'd have to.


"---vender?"


She shook her head, looking to her right.


"Lavender? Hello? I have to go, 'kay? Quidditch practice and all." Ron let go of her arm and placed a kiss on her cheek, "See you in the common room?"


"Oh, yeah. Quidditch.." She said, coming out of her thought. "Sure, Wonny. See you tonight." She gave him a vague smile and headed off, towards the Gryffindor common room. After a few minutes' trekking, she reached the Fat Lady, and said blandly, still in thought, "Abstinence.." She hadn't even the time to realize the irony in the password before the portrait swung open and she'd climbed through.


Quietly scaling the stairs to the top, she entered the girls' dormitory, shuffling over to her bed. Lavender sat down and, rummaging through her trunk, removed a hefty brown package from beneath some robes. Tearing the packaging neatly open, it was revealed to be a book titled The Change, by Androgiana Walhart.


She waited until the weekend had approached before taking action. The book said that to complete the ritual, it had to be done in the nude, surrounded by warmth, and a smell that reminded the caster of sex. The conditions needed to cast the spell were nowhere to be found in Hogwarts but, remembering the D.A. the year before, she was struck with an idea.


Saturday arrived, and Lavender Brown could be found nowhere within the castle. She'd told her friends she needed some time alone for personal reasons. Even the Marauder's map couldn't have seen her. She'd taken up in the Room of Requirement, having recalled the steps to get in.


The room was fairly magnificent, really. It was a warm, circular room, with purple curtains hanging about the walls. Amid the floor was a large amount of tissue paper (Lavender wasn't sure what it was for. Maybe it reduces some to crying..), a set of Hogwarts attire for a Gryffindor female, though the panties with it seemed larger than her normal size. The room was sort of hazy, with the heavy scent of Cinnamon and the smell of her bed's curtains.


Lavender sat in the middle of the room, naked. She'd taken off her clothes for fear of grafting them into her skin. The book had warned her such things could happen. The book itself lie open, on the page that described how to cast the spell, and what the caster should be doing.



"The caster of this spell should be sure minded. She who is not daren't attempt for fear of mutilating themselves. To cast the spell correctly, the following conditions must be met:
The caster must be in a closed environment, with little, and preferably no distractions.
The atmosphere should be warm and comfortable.
The caster should have an image of what they want their new parts to look like clearly set in their mind. It is best, for those under the legal age, to imagine a phallus of no more than seven inches, the tone of their own skin, with or without a foreskin. Also, testes should be taken into account.
The change will cause very, very odd feelings within the caster's body. This is, of course, due to the fact that you are not just changing your appearance, but your body's physical form. The spell changes the feminine parts within, and without the body. The uterus and all associated parts will sort of dissolve, and could be painful. Then, the skin will start to form, as will new muscle, blood cells, nerves, etcetera. For most, the experience is orgasmic, but for some, could be dreadfully painful. Good luck, my dearies. And enjoy your new parts.
Also, it is most unwise for any women carrying child to try this spell. It can, and will liquefy the child."



That was only one of many different spells of its kind. There were many variations for males and females alike, with different amounts of transfiguring to be done. Most of the pages, though, were devoted to the theory of sexually changing spells, and so forth. It had many moving illustrations, as well. Lavender had used the book on more than one night leading up to the Saturday, but not in casting spells.


Taking her wand into hand, Lavender lowered it to her nether lips, having been advised by one passage that some fluid from the sex can enhance the spell. Her wand slid past her lips, the mahogany gliding in smoothly. She gasped, her legs instinctively clapping together at the knees.


Lavender withdrew the wand from her muff and held it up. The juice she had gathered was glimmering in the dull light of the room, and dripping down to her knuckles. She then arranged herself in the middle of the room, on her back, staring at the seemingly endless ceiling, holding her wand steady in the air.


Her breasts were separated by gravity, each to one side, her large, pink nipples soft in the warm air.


With a sigh and a reassuring look at herself, she waved her wand in an intricate fashion, ending the wave with the tip of her wand pointed at her groin and said in an unusually heated voice, "Virtuseo!"


Lavender groaned, her body arching high off the soft floor. Her smooth, pale skin rose all over in chill bumps, even the warm air unable to stop her nipples from hardening. She writhed for a moment in agonizing pain as her sexual organs melted away, but the groans in the air were shattered by a thunderous moan.


The change took place within all of about half a minute. She gained just what she wanted: A six and a half inch long, 1 1/4 inch thick, pale cock, the head half-covered by a soft foreskin, as well as a hefty set of matching testicles.


The intense sensation brought her involuntarily to her first climax, sending a thick spray of seed up into the air, landing heavily onto her well rounded breasts and her stomach. She lay there for quite some time, breathing hard. Her cock had since gone limp, and was laying heavily upon her thigh, leaking remnants of her lust.


The smell of her semen was intoxicating, making the already hot air even more warm and fragrant, to boot. After a while, Lavender decided she'd better clean up. She looked first to the tissues, considering doing it the old fashioned way. Then to her wand, considering Scourgify. In the end though, she scooped up the thick liquid with her thumb and sucked her digit clean with a soft noise of like.


About the time she'd finished, she felt odd again and, looking down, discovered she'd become erect again.


"An issue of Playwitch would be great about now.." She said, fondling her new appendage. As she turned her head to survey the room, she noticed, atop the pile of fresh clothing that had come with the room, just what she wanted. Grabbing the magazine, she flipped through the pages, finding on a blazing white page about near the center, a moving image of Brazilian man, draped in Quidditch robes, having a very heated sex session with whom appeared to be a team cheerleader.


That image was more than enough, and she'd gotten off four more times to it alone before she realized her cock was starting to hurt from the constant exercise. So, standing, she headed over to the fresh clothes and started to pull them on. Once dressed, she discovered why the panties had been a bit bigger in the front: To make room for her new bits. Also, they seemed to shape on her butt better.


The Gryffindor.. girl, boy, whatever she was.. grabbed her wand and stowed it in her robes, as well as both The Change and Playwitch and headed back to the common room with a devilish grin on her face. It was late; much later than she'd thought, and Ron would be there..


On to Part Two!
