Albus Dumbledore is no more! His machination gone! The former headmaster of Hogwarts had been replaced by a being originated from our world. It is time to teach those naïve b-witches how to truly serve the cause and defeat whatever his face. Pure Smut! Evil OC!

– Witch Trainer –

Professor Albus Dumbledore matched my gaze. I tilted my head to the right. He tilted his head to the left, mirroring me. I raised my right hand and rubbed my long grey beard. He did the same, only with his left and in the opposite direction.

"How bizarre," I said and averted my eyes from the mirror and scanned the room. The layout of the room was oddly familiar even though I had never set a foot in this place before. I stroke my beard once and sat down in my chair. I leaned back and eyed the door across the room. I pondered to what I should do next. The goal should still be the same – probably.

"Status," I thought. A blue screen obscured the centre of vision. A picture appeared in the top right corner while name and status of the person I currently inhabited appeared on the left. A brief history of the man appeared at the bottom. "Albus Percival Wulfric Brian Dumbledore – that's a mouthful – age 113. Well, this is definitely the universe of Harry Potter and I just became headmaster."

"Abilities," I thought and brought up my abilities window. I needed to know what abilities were still available to me as the rules of each universe were slightly difference. "Huh? First Person Shooter is still available?"

"Inventory," I immediately thought and brought up the inventory. A grin plastered across my face as a Desert Eagle manifested in my hand. My finger ran across the cold steel with glee. I pointed at the door across the room. "Bam! Boom! Let's see if wizards can dodge bullets. I'd always want to know that answer to that."

I put the gun back to my inventory and returned to my ability list. There was almost a dozen listed with a handful greyed out one. Those cannot be used in this universe, which was a bummer. The white ones were the abilities I acquired when winning each of his game. The green coloured ones were available only temporary. "Master Manipulator? Must be one of Albus' ability. Allowed me to manipulate the action of others – so it's basically the same as Voice of Persuasion? Well, that makes thing easier for me –"

There was a knock on the door. I turned towards it and stroked my beard. "Come in?"

"Professor Dumbledore. You wanted to see me?"

I arched my brow and eyed the young girl. "Ah yes, Miss Watson. Do come in."

"It's Granger, professor," Hermione said and approached the desk. She stopped in front of it, giving me a closer look. She was wearing the standard uniform of Hogwarts which included a knee-length black pleated skirt that overlapped her white socks. The top was a long sleeve white shirt covered with a cardigan and tie that displayed the scarlet and gold of the house of Gryffindor.

"Cute," I thought and eyed her chest. Under those boring attire, she was supressing some impressive large breasts if I recalled correctly. It had been a few worlds since I got murdered on Earth – the first one. "Let's start with her."

I cleared my throat and looked thoughtful for a moment. "Miss Granger," I began slowly. Hermione gave me – her professor – the upmost attention. "As you might have known. We are living in dark times. Even a powerful wizard like myself can only do so much."

Hermione took in the words. "What do you need me to do, professor?"

"Smart girl," I thought. "Too smart for her own good. Well, if she was a dumb bitch then there was no fun in breaking her."

"I need allies, strong allies that I can depend upon in time of perils," I said and gestured my hand at her with a smile. She was beaming with pride. She was thinking that I was referring to her. "You are the most gifted and talented witch I have ever seen. This task – I cannot do it myself, and that is why I needed your help."

"I will do whatever it takes to complete the task, professor," Hermione said with full confidence.

"I'm sure you will as I have seen numerous report of your unwavering dedication to your friends and to Hogwarts. With your help, the forces of evil shall not prevail here," I continued, stroking her ego. I allowed time for my words to sink into her psych. "I need you to collect essence – sperm – from the students."

Hermione took a moment to snap out of her smile. "E-excuse me!? W-what did you say professor?"

"I need you to collect some essence from the male students," I repeated the task and stroked my beard. "You see, I am developing a weapon against –

"You-know-who?" Hermione whispered.

"Who?" I questioned before coughing. "Yes, yes, I know who, he-who-must-not-be-named."

I wished the entire wizarding world would pull their head out of their asses and called the damn guy for what he is. He didn't seem all that invincible from the movies. A bullet through his head should put him in his grave. If he gets up again, another bullet would do the task.

Like most wizards and witches in Hogwarts, Hermione Granger seemed to be terrified of the guy she had never met in person before. I let out a small sigh. "The male essence is the main ingredient and I, unfortunately, cannot request such a thing myself without disclosing my secret plans. As such, I must shamefully request this… degrading task… of you."

"I…" Hermione muttered. Carrying out such a task was the last thing she wanted to do.

I let out a heavier sigh. "If you are not up to the task, I'm sure there are outgoing witches willing to help me. Although, I cannot ensure their loyalty to such an important cause, unlike you, my dear. I must request that you forget everything I have said just now."

"I'll do it," Hermione said as I raised my brow. "You can count on me, professor."

"Marvellous," I said and looked about for a cup. I settled on the golden goblet on the table. I picked it up and handed to the girl. "Here, fills this goblet with the essence of a student and bring it back to me. I wish you the best of luck, Miss Granger."

I watched the young witch left the room with strong strides and golden cup in hands. I wondered if she would do it. It would be fun to see her try. I returned to checking my attributes. Since I took over a body instead of spawning one, I should gain all the abilities and powers of Albus Dumbledore.

Hermione came back an hour later. I thought she would take longer. Maybe she gave up?

"Welcome back, Miss Granger. I take it that you have accomplished the task?"

"Yes, professor," Hermione answered. "It was quite embarrassing, but I have accomplished the task you gave me. My friend Ron was weird out at first, but he said he too would want to do anything to help defeat you-know-who."

"Did he now?" I asked and eyed the pitiful amount inside the goblet. It must had gotten Ron some time to ejaculate that much. "How did you collect his essence?"

"Umm… he took the goblet and went to his room…" Hermione muttered and averted her eyes from mine.

I stroke my beard before clearing my throat. "I am disappointed in you, Miss Granger. How do you know that this is what I required? Did you see it come directly from the penis and into the cup?"

"No, professor," Hermione mumbled. "I did not."

"And I did say fill this goblet, did I know? Such a pathetic amount is completely worthless to me," I said, raising my voice, causing the girl to flinch. I appeared to be furious with her. "And did you not listen? You do not and should not tell a single soul of why you are collecting their essence. Can you imagine what would happen if a word got out? All the years I prepared would be gone for naught."

"I'm sorry, professor," Hermione uttered. She was on the verge of tears.

I immediately calmed myself and leaned back on the chair. An expression of disappointment filled my face. "It's alright, Miss Granger. I supposed this task is too difficult. I might have misjudged your talents. You should return back to your dormitory."

"No, professor. Please give me another chance," Hermione uttered with teary eyes.

I stroke my beard and smiled warmly. "Very well, but you must not forget a word I have said, Miss Granger. You must not tell a single soul of what and why you are doing this."

"Yes, professor," Hermione responded.

"For today failure, I will need to punish you," I said and continued to stroke my beard. "Perhaps a little spanking is in order."

Hermione widened her eyes. "Spanking is barbaric, professor!"

"Only through physical pain you will learn your mistakes," I said. "I am old fashion that way. Now, please come here and lean on my desk. It will be over in a few minutes."

Hermione hesitated for a moment. She reluctantly leaned over the table as I got up from my seat. I approached her from behind and slowly lifted her skirt up. She must have assumed that she would be spanked through their clothing. She assumed incorrectly.

With a stern expression, I examined her underwear before hooking one finger and pulled it down. At that point, she jerked upright and tried to get off the table. This was clearly cross the line. I used my left hand pressed her back onto the table. She might be a witch, but without her wands, she was just a weak girl. Her bare bum received a few playful slaps. It was nice – very nice.

When I returned to my seat, I could see her tearing up again. Damn, she was cute. I could feel myself getting hard. "That wasn't so bad, right, Miss Granger? A little pain goes a long way."

Hermione shook her head and tried to clear her tears.

"I will let you on a little secret, Miss Granger," I said warmly as I looked at her. "I believe you are the child of prophecy, a maiden who shall vanquish the darkness." My hand picked up the goblet and extended to her. "However, no single person can extinguish such evil, as such you will need to take in the essence of others. They will imbue you with the strength you need."

Hermione was in utter shock. "You can't be serious, professor!?"

"Quite serious, my dear. If you wish to get rid of you-know-who, you must set your dignity aside and do what is right. Drink the essence you collected and show me your conviction," I said with a serious face.

Hermione took the cup in her hand. It was too much for her to take in while swirling the cum in the goblet. She was obviously weighing her options. Before long, she took the goblet to her mouth and took one big gulp. She quickly made a face of disgust afterwards and tried to not barf.

"How do you feel, Miss Granger?" I asked.

"I… I don't feel any difference," Hermione said. She took out her wand and had a test. The spark that came off at the tip gave me a bit of amusement. "I think it's a bit brighter."

"Really?" I thought. "That's is great. I always knew you were the one."

Hermione was filled with confidence once more. It was so easy stroking her ego, and thanked to the passive abilities I have, she was easily taken for a ride. I watched her smile as I stroke my robe under the table.

"Holy shit, Albus is packing," I thought as I made out the size of my dick. He was huge, sporting at least 6 inches and this was not fully erect. I wondered how big I could get. Well, there was only one way to find out. Luckily, there was a fap material nearby.

"I supposed I should do my part as well, Miss Granger," I said and got off my desk. "Please get on your knees and hold up the cup"

Hermione looked puzzled for a moment and dropped to her knees. She held up the golden goblet as I opened my robe and let out my dick. "W-what are you doing, professor!?"

"I'm helping you achieving your destiny, Miss Granger," I said as I began to stroke the snake while looking down at the shocked teenager. It wasn't difficult getting hard once I thought about coating her face with my spunks. "Do not take your eyes from me. This is the only want to ensure that it is truly male essence you are collecting."

My dick continued to grow as I watched Hermione stared at me. I let out a heavy groaned as my dick soon reached critical mass. "Hold it still!"

Hermione didn't look away as I spewed thick discharge. Ropes after ropes of semen filled the goblet to the point to of overflowing.

"It's too much, professor!"

"Hold still, damn it," I grunted as sprayed some onto her hands, coating her fingers in slimy layers. I let out a deep exhaled as the last couple of spurts filled up the cup. "There you go, Miss Granger. I hoped this will give you the power you need."

Hermione placed down the cup and looked at her glazed hands.

"Please don't waste any, Miss Granger," I said and pointed at her fingers.

Being as bright as she was, Hermione understood the unspoken request. She reluctantly slurped up her cum coated in her hands. She looked just like a cat cleaning her paws.

"Well done, Miss Granger. I knew you could do it," I gave her some more words of encouragement. I smiled as she picked up the goblets with both hands. With a couple pause of hesitation, she brought it to her lips and took in a mouthful. Her throat constricted as she tried her best not to throw up. She arched her head backwards and swallowed the load in her mouth. She panted soon afterwards and looked up at me.

I responded with a smile and a nod while stroking my grey beard. I watched her downing the entire cup with great effort and even let out a small burp at the end.

"There is no doubt in my mind now, Miss Granger. You truly are the chosen one," I said and helped her onto her feet. I gave her a tight hug soon after.

"Professor, your… your thing is…" Hermione uttered as my hard cock poked her chest, staining her uniform.

"Ah yes," I replied and covered myself. I feel like I could go again but ejaculating into a cup was no fun. No, I wanted to dump straight into her stomach from the top and the bottom. Unfortunately, I shouldn't push her too hard. If she refuted too strongly, she would break out of my control.

"It is getting late, Miss Granger," I said. "While you failed at your task, at least you have grown a bit today. Off you go, and don't forget your underwear. Please come and see me tomorrow morning."

Hermione embarrassingly picked her panty off the ground and headed towards the door while trying to cover her bare bottom. She gave me a bow before leaving the room. I only give out a chuckle and rested on my chair. What should I have her do tomorrow?

– Witch Trainer –

Hermione walked into my office the next morning as I had requested. Her face was full of conviction, and her body was full of vigour. It appeared that what'd happened yesterday was no longer on her mind. All the better, I supposed. I thought she might not show up, but I guessed her ego was bigger than her brain.

"Miss Granger, you seemed to be a good mood today," I greeted.

"Good morning, professor," Hermione said. She heaved her chest slightly. "I will not fail you."

"I know you won't," I said with a smile and gestured her towards the desk. "I have thought quite a bit about yesterday and found the goblet to be a hindrance. Why don't you just harvest the essence directly from the source?"

"Pardon, professor?"

"I mean use your mouth, my dear," I pointed out. "Everything is going to end up in your mouth in the end anyway? Besides, that way, you won't spill any."

"But professor!"

I raised my hands. "I know, I know. This will be the first time you did such a thing, but I am here. I will help you practice harvesting essence. Please come over this side so we might begin."

Hermione followed my request, reluctantly. I pushed the chair away from the table to give her some room. I opened my robe and revealed my growing erection. She looked at it and swallowed before kneeling between my legs.

"You looked very pretty, Miss Granger," I commented as I stroke my dick. I liked to play with her tits sometime soon, but one step at a time.

"Thank you, professor," she responded and looked at my penis. It was sporting almost 9 inches. The old man must be well-endowed when he was younger.

"Hold my cock and aim it at your mouth," I requested. She timidly followed the request and held the end of my shaft with both hands. The softness of her finger caused it to jerk happily. "Now, stroke your hands up and down, not too fast and not too slow either."

Hermione followed the request, slowly, all while watching the end of my cock.

"Stroke it all the way to base, Miss Granger," I said. She did as her fingers came in contacts with my balls, "and give it a squeeze every now and then. That's right, that's right. Just like that, oh yes! You are very talented, Miss Granger."

The encouragement seemed to bring life to her hands. She continued to jack me off until I felt a surge in my balls. I only let out a groan as a warning before the first spurt slashed against her face, coating her features with spunk.

"Miss Granger!" I called out as the second blast masked her uniform, drenching it in stickiness. "You are wasting my essence!"

"But professor!" Hermione called out before I grabbed the back of her head and pulled it towards my shaft. She let out a yelp before her mouth was plugged shut. Her eyes widened as the third spurt blasted straight into her throat, choking her. She slapped my thighs and demanding me to stop.

"Now, now, Miss Granger, a little discomfort and you're giving up already?" I asked and plunged my shaft deeper into her throat, filling her stomach with milky breakfast. I could feel her swallowing rapidly, trying to breath. Her eyes rolled upwards as her consciousness waned. She soon passed out from the cum overflow.

I sighed and pulled my massive erection from her tight throat as it continued to erupt ropes after ropes of cum into her mouth. I gripped my dick and aimed at her face, coating it in white along with her uniform.

"Passed out already," I muttered and emptied my balls onto the unconscious girl. She was drenched heat to toe in spunk. "Fuck, I sure came a lot. Good things the school is filled with fuckable bitches."

I took out my wand and levitated Hermione to my bedroom. It would take a while for her to wake up again. Once she did, I returned to my desk and called up a few clean-up spells. They came naturally to me thanked to countless years of practice. Magic sure was handy.

I practiced a few more spells until there a knock on my door. A blond-haired girl with pale silvery eyes opened and entered the room. She looked around the room with bewilderment. Was it the first time she been here?

"You asked to see me, professor?"

"Ah, Miss Lovegood," I greeted with a smile. "Yes, yes. Please close the door. I have the most urgent task to ask of you. It concerns the fate of the entire wizarding world."
