She closed her eyes and centred herself on the feel of his fingers beneath her chin. He spread his palm flat across her neck and left it there and she could feel her pulse battering beneath his hold. She recited the spell in her mind over and over, listening intently for the faint sound of a second heart. Draco’s steady breathing helped her keep time and then there, in the centre of her chest, another beat thumped away beside her own human heart. His hand left her neck when she felt her very existence ripple in and out. She was half part of this world, half part of another. An instinct she didn't know she possessed took her over, It flowed through her body like hot lava igniting every nerve and muscle. Her legs stretched out and her back arched forward until her hands hit the grassy earth. In their place was a pair of huge paws, sharp claws glinted from the mass of fur, digging into the dirt, sharp as knives. Huge teeth grew through her gums, elongating until two sharp fangs stretched from her top gums and two smaller fangs appeared from the bottom. It was all very strange to have one's body stretched over new bone formations, to stand with her hands on the ground. Her back legs took a tentative step forwards. The ground was soft and welcoming on the pads of her paws and Draco’s telltale scent of Apples and sugar assaulted her even more than usual when she breathed in through new nostrils. Without warning her new instincts took over, she wanted him, she could smell how incredible he was and she wanted him closer, as close as possible. He was hers.
