Note: this chapter contains smut. Bellatrix is almost seventeen at this point in the story. Obviously, it's a teacher/student dynamic so there's a significant power imbalance. Please don't read if that isn't to your liking. This chapter is purposefully a little shorter than chapter 4 which features more plot development (and her seventeenth birthday party).
Bellatrix regarded Professor Riddle with a quizzical look, wondering which books he had brought her from his personal library. She heard him utter a quiet Muffliato spell, and he now appeared to be casting all manner of complex warding charms over the classroom.
"We wouldn't want just anyone listening in, Bellatrix."
"Of course. I understand that these books are not part of the approved curriculum, sir."
"Let's drop the formalities. I've seen what you desire in your mind."
Bellatrix gawked, horrified at the idea of the contents of her mind being completely exposed. Was he a Legilimens?
"Yes, I'm a Legilimens, although I don't just use this ability to read all of my teenage pupils' thoughts. Your mind, however, intrigues me—I could detect the Darkness that resides within you on the first day of class. There are few witches I've met in my life who I can say that about."
His praise sounded like honey in her ears, although Bellatrix wasn't sure she was comfortable with his invasion of her privacy. It was one thing to have fantasies and desires when they were private, and another thing entirely to bring them into the light of day. Did he know everything?
"Yes. Everything. You see, I am an egotistical man, Bellatrix, who appreciates being reminded that I am the most powerful wizard in the world. I won't deny that it gives me a great deal of satisfaction to know that I can inspire lustfulness in a very pretty young girl."
"I…know that it wouldn't be proper. My birthday is on the 21st of September. It's only a couple days. Even then, it would be against all kinds of rules, so…" she trailed off.
Bellatrix wondered why on earth her mind was trying to fight what her body so urgently wanted. Perhaps it had something to do with how she had been brought up to be an aristocratic lady. But despite her mother's lectures on how her position as a member of the House of Black necessitated remaining pure until her wedding night, Bellatrix wanted to forge her own path in this world. She wanted to devote her life to promoting the ideals of the man who was standing in front of her, whom she worshipped with all of her being.
"I have never had much use for rules. I take the things that I want."
Before she knew what was happening, he was kissing her on the mouth. She was shocked with how rough it felt, but also with how much her mouth responded by opening to give his tongue admittance. He intensified the kiss, and bit her bottom lip hard enough that it bled, lapping at the scarlet rivulet that soon trickled down her mouth to her chin. It hurt, but the rush of endorphins in her brain encouraged her to dig her fingers into his shoulders while reciprocating his kiss.
"Such a pretty girl. And such pure blood," he whispered softly.
He then stroked her cheek, slowly bringing his thumb to her temple and tucking a stray curl behind her ear. The way he unpredictably moved from aggressive biting to the softest touch caused her body to unravel. She felt a familiar tug from her lower abdomen down into her core, and sighed.
"Does it please you when I touch you like this, Bellatrix?" he asked.
"Yes, Professor Riddle. Very much." The power of his magic sent shockwaves through Bellatrix's body like a thousand volts of lightning.
"Privately, you will address me as my followers do, as my Lord."
"Yes, my Lord."
"Good girl. Now unbutton your top."
She did as she was told, peeling off her robes so that she could more easily access the buttons of her white poplin shirt. She had on a grey and black cotton bra with lace overlay, and was thankful that she had the forethought to wear matching undergarments today.
"Take off your bra. You can keep on the skirt so that I'm reminded of what a terrible, wicked little schoolgirl you are for distracting me."
"Yes, my Lord." She hesitantly stripped off the bra, revealing her small but perky breasts that fit with her petite frame.
"Good. Now get on your knees."
"P-Pardon? ... my Lord."
"Are you deaf, Bellatrix?"
"No, my Lord." She immediately dropped to her knees on the cold floor of the classroom.
"You're a smart girl. Now figure out what I want from you."
She yearned to please him, but knew that her inexperience would be obvious as she crawled on her knees over to where he was standing. Bellatrix was about 5 feet 3 inches, and her master was almost a full foot taller. Her face was now parallel with the bulge in his trousers. She gulped, somewhat disbelieving that this could be taking place outside of her mind. Her hands moved to unbuckle his belt, and she gasped when she took in the full view of his erection. Bellatrix had never seen a wizard's anatomy before, but was certain it had to be on the larger side, as it was almost as thick as her wrist.
She cautiously began licking the tip in short, quick strokes, and gradually tried to take more of him into her mouth. She eventually figured out how to wrap her lips around his length while creating the right amount of pressure as she moved her hand up and down.
"Good girl."
Applying a firm hand to the back of her head, he started to force himself deeper into Bellatrix's mouth. Her first instinct was to recoil and try to get a breath of air, but her desire to please him triumphed over the mildly uncomfortable sensation, and she took him deeper.
"Fuck. Bellatrix," he groaned, "Such an obedient little slut."
His words made her tremble ecstatically. She knew other witches would find that word, slut, to be degrading, but coming from her Lord, she would wear it like a badge of honour.
After praising her efforts, he patted her head affectionately, knowing that what he was about to do would not be affectionate at all. He violently pulled out and rammed himself as hard as he could down her throat and repeated the motion several more times in quick succession. Her mind was blank; she simply couldn't think of anything as he thrusted into her mouth like it was between her legs. After a few moments of being used in this way, he found his release and she swallowed the streams of liquid shot down her throat.
"You did well, Bella. Would you like a reward?"
"I will accept any reward that you think fit to bestow upon me, my Lord."
"On one condition— that you recognize that your pleasure will always be secondary to my own. You understand me?"
"Yes, my Lord."
"Good." He shoved her roughly onto his desk so that she was sitting up and facing him, and used his knee to force her legs open. He then slipped a hand under her skirt, pulling her panties to the side. She moaned in delight and squirmed upon his hand.
"Oh. My Lord," she gasped, as he expertly began to stroke her clit with his thumb. He tentatively inserted a finger in her while keeping the pressure on her most sensitive area.
"Are you sure you're a virgin, Bellatrix?" She had seemed just a little bit too wet and excited, but he had detected no falsehoods in her mind.
"Yes, my Lord. All girls from families like mine are supposed to be virgins until our wedding night."
"But you fuck yourself with your fingers, like what I'm doing now?"
She was struggling to keep up with the conversation as waves of pleasure cascaded through her brain, voiding all logical thought. He slipped two more fingers inside her and she shuddered.
"Sometimes, my Lord. Mostly I imagine you…taking me. Making me yours."
"There's plenty of time for that to happen yet. All in due course, Bellatrix."
Her pleasure was reaching its apex and she could feel her muscles begin contracting around his fingers.
"Oh!"
Bellatrix came harder than she had ever experienced. He pulled his fingers out and motioned toward Bellatrix's mouth, urging her to taste herself. She obeyed, and licked her come from his hand while he gripped her chin firmly with his hand that wore the black stone ring.
She dressed in silence. He had been fully clothed, but flicked his wand so that her clothing returned to being unwrinkled, and even her makeup and hair were now tidied. She'd have to ask him how he did that eventually. Usually it took Bellatrix four or five separate spells to tame her wild, curly hair. A cooling, tingling sensation went over her spine, and her body again smelled like jasmine and vanilla, her signature scent. How did he know something like that, unless he was as obsessed with her as she was with him?
He was the first to speak.
"Your father actually sent me an owl today. Cygnus confirmed the transfer of 10,000 galleons to my account, you know, as a donation to the cause. I wonder if he would have sent the money if he knew what we've just done? What do you think, Bella? Would daddy be proud of his little girl right now?"
She felt nauseous and almost recoiled from him, but she realized then that his voice was incredibly sexy even when he was trying to humiliate her.
"I don't really get along with my father, my Lord. I confess to not caring much what he thinks of anything I do."
"Ah. We are quite alike. In fact, I murdered my own father when I was your age."
Bellatrix could hardly believe what he just said. She of course knew that Lord Voldemort was not a nice man. That was part of her attraction to him. He had tortured and killed countless people, mostly Muggles, and she knew that these days he had a gang of followers who carried out attacks on his behalf.
Cygnus Black was not involved in this bit of business—he handled Tom's financial interests—and so Bellatrix hadn't a clue how much she could believe of stories she occasionally read in the Prophet about some Muggle family slain in their home with signs of Dark magic being involved. Bellatrix knew a good portion of these cases could likely be traced back to an order that came from Lord Voldemort himself; nevertheless, something about the intimacy of his admission startled her. She knew that she must contain her emotional reaction, lest she appear weak.
"I'm sure you had your reasons, my Lord."
His lips curled in that delightful way to which she had become accustomed.
"Indeed. I did. Perhaps someday I will tell you about it, if you remain loyal to me."
"I will always be loyal to you." The words came from her lips instinctually.
"You will not say a word of this to anyone. Not even to your sister. If you continue to please me, I will see to it that you have a place in my movement after graduation."
"Thank you, my Lord."
"I have work to get done, now. Run along and take these."
He handed her three books: Magick Most Evile; A Curse for Every Occasion (Expanded 50th Anniversary Edition) by Silvanus Sangfroid, and Harnessing Darkness by Endymion Rundle.
"I'm counting on you to impress me with this plan of yours on Halloween."
"I won't let you down, my Lord."
