Katrina is mine, the rest are not.

The children gathered around the platform. Professor Lupin stood in the throng waiting for their guest to arrive. Severus Snape strode in, arms crossed over his chest and moved to the back of the room where he leaned against the hall. The children were chattering in anticipation of this evening's lesson, one that he himself had been eager for. A slight breeze permeated the room and a few of the sconce flames were extinguished. Several of the children looked over their shoulders and a girls hair whipped as a breeze passed her. He heard a whisper of a voice, "beware little children," he suppressed a grin as a girl shrieked, slapping at her arm and whirling around. Soon all of the children were in motion, "fear me if you will," several more children exclaimed in fright as they swatted at the wispy tendrils of fog that spiraled through them.

Snape himself was touched by what felt like a soft kiss on his cheek, he remained impasse as he heard her voice in his ear, "little one. . ."

A moment later that voice spoke from the darkness at the far side of the room. "Had I wanted you all dead, you would be," she said as she emerged from the shadows. Dressed as she had been the previous night, her appearance was, more or less, that of any other person.

Suddenly she pounced forward, bounding like a cat on all fours for several paces and just as she reached the students, sprang up. The students under her shrieked and grabbed their heads as if to protect themselves, a reaction he would have been pleased to have caused himself, Severus thought.

The woman landed soundlessly and stood, motionless except for her head which she turned to look at each student in turn.

"I am Katrina," she spoke with a powerful, confident voice, "I am Vampire." As the students started to mutter she yelled, "silence! You will not speak unless spoken to!

"I trust you all know what a vampire is? Good, some of what you have heard is true and some is not. If you wish to defend yourselves you must learn such. I will need a volunteer. You," she pointed to Draco Malfoy, "come," she motioned him on the platform with her hand. "You will stand there and you will try to kill me."

Draco looked over to where his head of house stood, saying nothing only raising his eyebrows at the boy.

"The great wizard has permitted you to use all spells at your disposal."

At the boy's confused look, Remus Lupin cleared his throat, "Draco, what she means is, Dumbledore says it's ok, use anything but the unforgivable curses."

She nodded at him and then turned back to the boy, "begin!"

As Draco smiled and began hurling curses at the vampire, she simply stood still letting them hit her full force, none seemed to have any effect on her. Finally she held up the palm of her hand, "enough! You may get down. As you can see these spells have been useless," she turned her head sharply looking at the other students. Several of them opted to try and curse her to no effect. The last was Hermione Granger who after several useless spells started to turn away, only to turn quickly and shoot fire out of the end of her wand.

Katrina leapt straight up where she hung at the ceiling for a moment before falling down, landing on all fours like a cat. "Good. While fire may not kill a vampire, none are immune to it and that is where we must begin. Alas there is 'no' spell that would kill me. Any other suggestions?"

"Holy water?"

"No, I was once a creature of god, water will not harm me."

"Garlic?"

"Useless."

"Sunlight?"

"It is true that the sun kills vampires, but you must lure one into the sun, and that would be difficult."

Silence filled the room, "is there none who has any other suggestions. Come, think."

A voice finally drawled out from the back of the room, "I could cut off your head?"

Katrina suddenly vanished only to reappear next to the potions master. She stood emotionless, chin held high, looking him in the face, "and how would you incapacitate me enough to do that, little one?"

"Perhaps a silver stake through the heart?" he replied.

Pulling a silver stake from her belt, she held it up to the light, "yes, a silver stake," turning she tossed it into the crowd, where the children passed it around as they examined it.

"Silver or wood will not kill a vampire, after it is removed he will come back to life, no you must decapitate it, or remove the heart." Jumping back onto the platform she pulled out her sword and held it up, "one of these works efficiently."

"Questions?" She said, pausing.

Harry Potter raised his hand and she nodded at him, "Hogwarts is protected by wards, how is it that you can come in here and does that mean other vampires can get in as well?"

"How can you stop the air from going where it wants to child. I am an ancient one with powers only a few other vampire have attained, but even the most stupid of beings can occasionally be resourceful enough to be of danger. How was it the great evil one was able to enter? Any other questions?"

"Is that a wand on you belt? Are you a witch?"

Katrina pulled out a white wand, attached to one end by a piece of leather was a small leathery looking object. "Yes and yes."

The children eyed the wand for a few moments, "is it made of ivory?" one asked.

"It is made from a bone from my fathers leg."

After a few groans from the students a red haired boy asked, "what's that thing on the end?"

"That is a debt repaid by Van Gogh, his ear," after a few more exasperations there were no more questions.

She continued for quite a time, carefully explaining they methods of capture, restraining and killing vampires. They discussed the habits and downfalls of the creatures, "a vampire also possesses healing powers," she said and pulled out her saber, "another volunteer?" When none stepped forth she inquired again, "is there none amongst you brave enough to help with this demonstration?" After a lengthy pause, just as she began to put her sword away, the potions master stepped onto the platform. She looked at him deeply and then back to the students, "at least there is one man among you!" she hissed.

Gently she took his hand and turned it palm up, she looked him in the face, which remained impassive as she drew the sword over his hand, drawing blood. A few of the children groaned as she held his hand, dripping blood for all to see, before she brought it to her lips. As she slowly licked the wound with her tongue her eyes remained fixed on the man before her, his face as emotionless as hers. Her tongue slithered in and out of the wound punctuated by the gasps of the on lookers. Once again she held his palm to the students, now completely healed. With a nod to Severus, he departed once again to the back of the room.

Continuing her lecture until satisfied, she dismissed the class.

Severus remained after the others had left and she went to him silently. Gazing into each others eyes, she asked, "I wish to have your 'company' again tonight if that is acceptable?"

The dark man raised his eyebrows ans inclined his head. They exited through a back door and went to his rooms in the dungeon. Sparsely furnished with no embellishments, she noted, much like her own home.

"Have no fear that we will be connected with my taking of your blood, as well, if you should taste my blood it will have no effect."

"Do you think I might be compelled to bleed you dry?" He inquired dryly.

"No, but pain and pleasure go hand in hand little one. Do not worry that you will hurt me, I assure you I will enjoy it all."

He felt himself harden at the thought and they moved together, viciously attacking, ripping off each other's clothes. Katrina arched her back as he bit deeply into her shoulder, roughly massaging her breast. She grabbed his hair and pulled his head up crushing his mouth under hers as he was forced back to the wall. Snape pushed her back and slapped her hard across the face, stunning her for a moment before she grinned at him, her sharp incisors flashed and then retracted. He moved forward grabbing her and pushing her back to the table where he spread her legs and thrust into her deeply. Clawing at his back, matching thrust for violet thrust they savaged each other until spent.

Severus took her by the hand and over to the bed where they lay for some minutes. Katrina lay on her side stroking his arm, "beautiful little one." Leaning over she traced a scar on his arm with her tongue, licking, suckling until the skin was healed. She touched a scar on his side and turned him gently to look at his back, inhaling sharply at the mass of scars cris crossing back and forth over his pale flesh.

She asked no explanation of him but spoke softly, "I could come back to you Ssseveruss, a little each night and you would be healed in . . . a few months perhaps . . .

He reached over and grabbed her hair, forcing her down on the bed and covering her lips with his, pausing for a moment to reply, "I would find that 'acceptable."

Redlady thanks for reading as always.

Lum, I too like the stories where all that lovely sexual tension builds up as they grow to appreciate each other etc. Thanks for reading my other story which you know is along those lines and I'm really enjoying writing that one. My intent with this one is different, I want the characters to be rough, raw and primal, starting a relationship that evolves from a mutual carnal need. Thanks for the review and I look forward to reading your stories.
