The new Calculus professor was like some darkly attractive character from a story. She was extremely tall; at least six feet. The woman stood straight, radiating strength, mystery, and danger.

Her hair was as dark as the night, kept in a low ponytail that looked almost princely.

Her eyes were dark and stormy, filled with an inner struggle that young girls were drawn to for some reason. It seemed that most teenage females were attracted to dangerous, risky looking people. Most cannot resist the danger that kind of inner turmoil creates. The woman's eyes were amber, seeming to glow with a strange yellow light, bordered by thick black lashes. They were sharp like razorblades.

She wore a men's style suit, which added even more appeal to her since she wore it so well. She had little curve so it suited her body type. The new professor also had a charming smile and teeth the color of snow that clashed yummily with her dark skin.

"My name is Valentine Hunter," she wrote her name on the chalkboard with neat, fluent writing. Her voice was deep, yet seductive like liquid gold, just like her eyes. The husky tone sent a chill up every girl in the room's spine, blushes scattered across the room. A slight accent in her words made it obvious she was not from Japan. "I'm your new Calculus teacher since, tragically, your previous one passed away." Gasps of shock filled the room.

No one had liked the old teacher, but that didn't mean they wanted him to die. "I am terribly sorry to any of you if it was a serious loss. However, in this world, things come and go. I truly hope you will enjoy having me as your professor, if you have any questions don't hesitate to ask. Or even any personal problems."

"She's so nice…and pretty."

"I'm glad Professor. Rokujo died if we get a hottie like this!"

"Damn she looks kinda intense."

"She's so beautiful!"

"I'm going to do my very best!"

The words fell on her ears, and a smile touched the professor's lips. Who would have thought joining the faculty of Kuoh Academy where her target, Rias Gremory, could be found would be so easy?

She was surprised by how many beautiful girls there were in this class… and such lovely breasts on their youthful bodies as well.

And thankfully, Valentine didn't even have to dispose of the old teacher who had actually been killed before she joined. A truck had hit him head on, a drunk driver, who died as well. She was lucky; she had come at just the right time. Valentine had easily created a fake version of all the information she needed, a birth certificate and a background, etcetera. She was good at things like that and she had some powerful connections whether it in the remaining groups of organized crime, or even the government.

"Any questions," Her sharp electric eyes scanned the class, the girls were going wild along with a couple boys who were into "dominant chic's" if she heard them correctly. She had always thought the idea of a man touching her body disgusting, so she was pleased to see she only had a few male admirers.

Less troublesome male heartbreaks and crushes. Her eyes fell on a single girl, who was completely silent, golden eyes narrow as she gazed at Valentine. Valentine felt her knees go weak as the scent of the stoic looking girl filled her nose, making her mouth water. No! She couldn't lose control...but the girl smelled so delicious. And she was so beautiful too, despite having such tiny breasts.

While Valentine preferred larger ones, she could make do with ones of smaller size.

Jaracara were not known to many, "native" to Brazil. To put it simply, they were breast milk vampires but they could also drink blood. Though it was much less appealing. They were powerful creatures. History knew them as monsters that preyed upon women's breasts while they were sleeping.

One ability that they had was charm-tongue: they could seduce using words. History depicted them as reptilian, which was only slightly true. Their eyes became reptilian along with their tongue when they fed, and they had the ability to speak to snakes.

Another thing they were capable of was changing the size of their prey's breasts; size changed the flavor of the milk. It was always sweet, but smaller meant sweeter. Valentine didn't like sweets very much.

However, she could make an exception for that strange white-haired girl who smelled delicious.

Valentine didn't get out much, she was raised on Earth in Brazil, and she had never encountered another supernatural being other than her family and a few other Jaracara's, also a couple low level demon's on Earth.

What was this girl? She knew they could not be human.

The girl was cute and petite with hair the color of snow, and ice-cold golden eyes that made Valentine want to melt into the floor.

She wore the uniform of Kuoh Academy well; it suited her cute, fragile appearance. However, Valentine in no way thought this girl was weak. Those electric golden eyes showed just how strong she was, full of an independence unmatched by even most adults. Her skin was pale, and seemed unnaturally soft; Valentine longed to have it against her own. What was this strange feeling..? She could watch the girl for eternity and still not tire of it.

No one had questions, and as she nodded shortly, the white-haired girls gaze slid away from hers. She felt a twinge of disappointment, but focused on teaching.

"P…professor!"

Valentines hands lightly squeezed the girls breasts; The schoolgirl was pretty, and had decent-sized breasts. Nothing a little magic couldn't fix.

"What's…happening?" The girl squealed. The Jaracara said nothing and just teased her breast a little more with her fingers.

The student was on her desk and had her legs spread willingly, eyes wide with need. "I feel so…so hot! I feel like I'm melting, more Professor, give me more!" She was almost ready to feast upon; the Jaracara would keep it to a single feeding for now.

She didn't think she was that lucky. Valentine teased the light pink bud of the girl's nipple with her tongue. Valentine clasped her hand over the girl's mouth as she screamed with pleasure. The "professor" felt her tongue extend and split, tugging even more.

"More …Professor, I want to be hotter!"

Valentine willingly obeyed, climbing above the teenager and readying herself for the oncoming flow of milk. When it came, she relaxed, suckling as if she were a babe.

Her cheeks were red with pleasure, human milk tasted so delicious. This was bliss, and apparently, the girl under her agreed because she was writhing with pleasure.

Despite how wonderful the idea sounded, and how much more satisfying it made a feeding, The professor didn't want the girl's soul. So she wouldn't kill her. Valentine didn't like to kill in the first place.

She lazily closed her eyes to the sound of the girl's ragged breathing, like a lullaby to her ears. The trickle from the breasts she was drinking from slowly died off.

Valentine pulled away and latched onto the other nipple, careful not to harm with her teeth. She had never encountered milk delicious enough to make her go crazy. She imagined the white-haired girl from earlier that day would.

She was growing drowsy like she usually did when she feeding but was already satisfied. Her eyes flickering shut. Her breath slowed, becoming even. While her prey's did the opposite.

The pretty student came just as the last trickles of milk dripped down Valentine's throat, she writhed beneath her professor who yawned and slipped away.

When her orgasm died away, Valentine lazily placed a hand on the girl's forehead, whose pupils dilated and glowed.

"You came for help on your homework, " Valentine whispered, her voice a low hiss. "Absolutely nothing involving magic happened. We had sex, but you won't tell anyone who would snitch on us. It's our little secret. I told you to tell your friends that they could come for any…help… they want. You'll have an A in my class if you let me suck your tits again. You'll do as I say…won't you?"

She didn't need the answer, she knew it already. Still, Valentine waited for the response.

"Of course Professor Hunter, I love you; I'd do absolutely anything for you." It wasn't the truth, but the schoolgirl thought it was. She would until Valentine released her from her enchantment.

"Lovely, my first pet. The first of many. Now, sleep." Without a word of protest the girl's eyes slid shit, and she fell into a deep sleep. Valentine eyed her handiwork, lightly stroking the breasts of the girl. They had been rather delicious... She was buttoning up the schoolgirl's uniform top when she heard someone walk into the classroom.

"Release the girl." Valentine felt her breath leave her; she fell away from the girl, knees going weak.

Such a lovely scent. Such a lovely voice.

Why…why is my heart pounding so hard? I can't breathe, I need…I need…so hungry. Blue eyes, like the ocean met her dark gaze . I can't resist her, she is so beautiful.

Before she could stop herself, Valentine crawled towards the unknown girl...no those were the breasts of a woman. A thought hit her. When had she fallen to her knees?

She looked up at the student. Her hair was red. Not an ordinary red, it could only be described as crimson. Like fresh, delicious blood...Darker than even the soft skin of a strawberry and her voice was just as succulent.

Valentines eyes slid up her curvaceous, womanly body, and her heart seemed to stop as her eyes met the beauty's chest. They were huge. The redhead's nipples were clearly erect through her clothing, or perhaps she wasn't wearing a bra...

The Jaracara needed to feed off her, her hands slid up the girl's form.

The student's eyes were freezing cold, but she didn't stop Valentine from unbuttoning her uniform top. As Valentines expected, her nipples were just so erect they poked through the cloth of her uniform. Her chest was clad in a dark violet bra made of lace. As the Jaracara's mouth neared a single breast, the girl grabbed her by the throat.

Valentine snarled, desperate for a taste of those breasts. The girl's cerulean eyes were dark with amusement.

"Absolutely pathetic, the first Jaracara seen in centuries and she's a weakling. Your kind is as ignorant and rash as always."

"Please…"

"You turn from your goal for something as vile as breast milk, for…." She lifted a single breast in one hand, squeezing softly, "these."

The Jaracara went wild as the redhead's breast bounced when it fell, her mouth wide and fangs fully exposed as she strained against the mysterious girls hand. "Pathetic. You can't even hear me, can you? So needy. I cannot deny I want you as well. I just have ten times more self control," The beautiful girl sneered. She shoved the Jaracara away, who panted. Her yellow eyes were slits dark with lust.

"I am Rias of the Gremory family. I will punish you for the sins you committed and for attempting to steal property of the Gremory family. For trying to steal the Grimoire of Honorius, I will end your life."
