Ruhk sighed and tilted her head back, small breasts tilted up and her hand sliding into the thick black tangles of Corr's hair.  She didn't try to help her sister or direct her tongue deeper.  The illusion Corr was attempting to foster was not like Ruhk's magical ones; it was more an ingrained habit, a need fulfilled by the trickery Corr perpetrated upon Ruhk - no matter who was laying claim to that name at any given moment.  The sister most commonly called Corr kept her tongue concentrating on the soft, sweet little pearl of the Ruhk-sister's sex, making her believe firmly she was and always had been male.<br/><br/>Frighteningly Ruhk often actually believed that very thing, far more deeply than Corr might have preferred at times.<br/><br/>The soft, warm caress of her twin's hand in her hair stroked and petted, and she lay back, letting Corr see up the line of her body as her breasts heaved gently, her breaths quickening slowly, eager.  The gentle hand caressed her face, traced her lips as she kissed and worked upon her sister the spell that kept her from becoming too violent.<br/><br/>For as long as it lasted.<br/><br/>Her sister jerked, bolted up right, her eyes wide and almsot angry.  She pushed Corr away from her nether lips, and then half-leapt, half fell into the tub, pushing Corr back up against the wall hard enough to drive the air from her lungs.  A hand scrabbled, clawed at her arm, then ripped the dagger away from her hand.  Ruhk's other hand grabbed, Corr's hair and dragged her head back so she could receive a soft, hot kiss upon her neck, her sister pushing her sleek, wet body against hers....and then the near agonizing pain of the hilt of the knife being shoved, pushed into her body, untouched and unprepared save for the tiny lick she'd given the pommel of the knife herself.  Ruhk growled, rubbed her body, her breasts along Corr's, the hilt pushing deeper as Ruhk thrust her hips between Corr's legs.  A near constant litany of hissing words, near too quiet to make out: curses, hateful demands, love-words, urgent desires, promises, deadly and kind.
