The attraction of blood for vampires was something that Kiara understood a little better than most non-vampires would be able to. She did not need the blood to keep herself alive, just their lifeforce, but it was something taken all the same. And she did need the blood. Without the blood she would likely still be living in Ireland and her sister would be - "Oh," Kiara's voice was actually a little disappointed when Nikita pulled herself away. The pain had really been nothing compared to the adrenaline rush it caused and she already missed the feel of it. New things, Kiara reveled in new things where she found them and Nikita had just given her a most marvelous one. Her mouth quirked up in a smirk when Nikita rose and she would have wiped her blood off the vampire's lips if not for the feeling of fingers in her hair. Kiara had been playing this game for centuries but it always held that extra bit of thrill when she went into it without the intention to kill the other person either because they were a man and that was what she did or because they were a woman and she wanted their blood. When it was sheerly for pleasure? She would not say that she liked it more because the killing really was her favorite part, but mmmm yet again it was new to taste her blood on someone else's lips.
Unlike Nikita, Kiara had never not thought about the possibility of this; she was a siren and she knew very well how people's natures ran. Pleasure was something they all wanted and if she gave them her blood, well, then they wanted it more. She was like every other siren she had met, to put it simply she loved being wanted and she was halfway certain that they fed on that as much as they did the men they had to kill. A groan slipped out of her mouth when she felt Nikita's fangs again and she wrapped her legs around her waist, not caring about the chill that emanated out from under her dress. She broke the kiss and brought one finger up to trace Nikita's jawline, that same smirk on her face as she tightened her legs to draw the vampire in tighter against her. Her skirt was going to be a mess by the time the night was over. Something in Kiara's eyes shifted and whatever look she had been wearing changed into something that she would have recognized in the mirror or the face of any of her fellows; lust tinged by a predatory hunger that just triggered whenever she was in this situation. She knew she was not going to kill Nikita, but her instincts were so attached to the thought... "I don't have sex on desks, Nikita... Nikita... let me call you 'Niki' tonight," her voice was a purr as she leaned forward. She did not hear the sound of a doorknob turning or catch the sight of one pushing open, she was a little too focused on pushing Nikita forward. The vampire may have been stronger than her, but she was full of siren's blood and Kiara knew how malleable they could be. Which was why she was able to hook her leg around her ankles and shove her onto the ground. Flipping her hair back she gave the prone vampire a grin that promised the world, kicking her skirt off so it stopped getting in the way, before she sank down to straddle the Russian.
That was when she noticed there was someone she did not recognize standing just inside the door. Kiara grinned at whoever it was and leaned down, claiming Nikita's earlobe and sucking hard enough to bruise for anyone lacking the healing speed of a vampire before she let it go to whisper, "Which one o' your grunts thinks they can watch? They afraid I'm going to kill you?" The siren laughed, glanced back up again and winked at the, ah it was a woman. "Don't worry, lass, I won't hurt her in any way she won't love. Will I, Niki?" Her voice had returned to the low purr with the last question and this time it was her who kissed Nikita instead of the other way around.
