Love Potion Gone Wrong

A/N: I do not own Harry Potter.

Love Potion Gone Wrong

Sitting in a dark room sat a being that was once a man, now he was more wraith than anything else, with his blood red eyes and slits for a nose he resembled more of a snake than the man he once was. Presently he was seated in an opulent chair decorated with gold and jewels, his mouth etched into a frown as he contemplated the existence of his greatest enemy, a 16 year old boy named Harry Potter when the doors to his chamber were opened and a strikingly beautiful woman with black hair and violet eyes entered, walking immediately to her master she knelt before him and kissed the hem of his robes.

“My Lord,” the woman intoned respectfully.

“Yes Bella,” the man replied to his servant Bellatrix Lestrange.

“I believe I found a way to take your revenge on Potter.”

“I’m sure you have my little viper, but I want to be alive when I kill his friends.” He chastised softly, his desire to kill Potter’s friends was brought on by the belief that the boy would only suffer more when they died and he couldn’t save them.

“I know my Lord that is why I believe this will be of great benefit to your plan.”

Curiosity piqued he motioned for her to continue.

“Master, in my studies of some of the Black family spell books I came across a potion that gives the user a great power.” She began to describe.

“Ah Bella, I think you may have forgotten what the word revenge means, I want to hurt Potter not make him more powerful.”

“Yes My Lord, but this power will only make the boy weaker. The potion gives the user the ability to control a woman’s body, but not her mind. In addition, the drinker becomes increasingly aroused and becomes almost completely irresistible to the women around him.”

“So the potion will make the boy become a sex fiend, this is not exactly a punishment.”

“No, its not. But this power gives him control over women only and over their bodies only. So while he may have the chance to have sex with as many women as he wants, they will still know what he is doing to them. This potion makes it so he cannot resist having sex regardless of whether the female wants it or not. This will drive his friends away and make him hated by all the women around him. He will lose his friends and allies being unable to stop himself, also his inability to control himself will make it so cannot train and become more powerful.” Bella finished, her eyes remaining averted from her lord.

The man, whom many had come to know and fear as Voldemort, sat back in his chair contemplating what had been proposed. He genuinely liked the idea, it was a plan worthy of his ancestor, the great and powerful Slytherin, it was cunning and ambitious, qualities Slytherin was known for and prized above all others.

Smiling, his yellow pointed teeth shown in the dim light of the room, he said “Yes Bella, I believe that this will be an adequate punishment. See to it, I want it ready before the week is out. We will launch an attack on the boy when he is in Diagon Alley, Severus tells me that he will be there on Saturday. We will use one of our hidden allies to force the potion on Potter before retreating.”

“I obey, my master.” Bellatrix responded before rising and headed for the door, eager to return to her lab and begin. This would earn great favor with her lord.

Entering her lab she began retrieving all the ingredients she would need for the potion. The last ingredient was one she would need to get, the blood of an innocent and pure girl. She had no time to go to one of the loyal pureblooded witches, but knew there was a muggle family in the dungeons who had a young daughter that would suffice. Picking up an empty vial she left to the dungeons.

It was a small matter to cut the girl with a dagger and fill the vial before leaving, she soon returned to her lab and prepared the potion. It’s color was perfect and now only needed to sit for a day before it would be ready.

The only problem was the small footnote that she neglected to read on the next page that said the blood of a muggle would cause the drinker to have the power over women’s mind as well as the lack of magic in the blood would be unable to block the ability to change a persons memories.

That Saturday Voldemort along with Bellatrix, the young muggle girl, who was under the Imperius curse, and several other minor Death Eaters were preparing for the attack on Potter. The plan was to portkey into the alley when Potter had been spotted and do whatever it took to stun him for a moment so that the young girl could force the potion down his throat. They would then leave as soon as reinforcements came making it look like they had been driven off. Potter would wake up being none the wiser about the changes that were being forced upon him.

A moment later word arrived that Potter would be leaving Gringotts in a few minutes, setting the destination Voldemort gathered his followers and vanished from his throne room appearing moments later in front of Gringotts with Potter standing right in front of them his retreat back into the bank cut off.

“Hello boy, you have escaped me for the last time.” Voldemort greeted his enemy, before casting the first spell of the day.

Harry woke up several hours later, a bitter taste in his mouth as if he has swallowed another of Snape’s awful potions. In addition Harry noticed that he was back in his room and that he had the single hardest erection he’d ever had, it was more than just a bodily action from waking up, he was more aroused than ever before. Still not fully awake Harry reached down and grabbed his penis stroking it gently.

By the time he heard his aunt yelling at him to get up and make dinner Harry was too concerned with pleasuring himself that she had already opened the door and was staring at him as he continued to pump his dick.

“You disgusting little freak stop that this instant,” she screamed finally getting his attention.

Pulling his hand off his dick he was horrified at what was happening, he was about to pull up his pants when a foreign thought entered his mind. It was telling him all the nasty things that his worthless aunt could be doing for him, all the pleasures her body could bring him. For a moment this worried Harry as his aunt was not a beautiful woman and was definitely not someone he had fantasized about, but before he could help it he had said “Aunt, you bitch entirely too much. It’s time you put your mouth to work doing something much more worthwhile. Now get over here and suck my dick.”

He was not expecting her to actually do it and in fact could hardly believe that he had said that at all, but to his surprise and his aunt’s from what he could tell from her face she walked over to his bed crawled on top of him and promptly stuck his cock in her mouth, sucking for all she was worth. Harry’s head fell back as the moist warmth of her mouth engulfed his four inch penis. Because of the lack of food during key times in his life Harry was not as big as he was supposed to be, at best he would naturally grow to a height of 5’ 8”, and that lack showed itself especially in the size of his cock. However he was blissfully unaware as he was almost painfully shy when changing at school and in the locker rooms especially, it had become something of a joke among his fellow players. As such he didn’t know that he was somewhat small for his age.

Moments later when Petunia was about to run out of air she pulled her head away from his cock and yelled, “What are you doing boy!? I know this is some sort of freakishness, and I won’t have it. Stop it this instant!”

Surprising even himself Harry replied with “Shut up bitch and keep sucking my big dick.”

Sneering she said “Big? Ha! Dudley had a bigger dick than you when he was six, you’re just a puny little boy.”

Angry Harry grabbed her head and forced his dick back into her mouth all the while just wishing that his dick was bigger so that he could show her that he was no ‘puny little boy.’ He never even realized what was happening until he felt a tightening in his balls and he came filling her mouth with his cum, some of it spilling down the sides of her face and onto her dress as she couldn’t hold it all. When he pulled out his dick it was still hard, but the thing he noticed was that after four inches it continued to come out of her mouth.

Whereas before his mouth was open in pleasure now it was gaping open in shock, continuing to pull his cock out of his aunt’s mouth it finally came all the way out measuring a foot in length and two inches thick at the base. The head almost wouldn’t come out of her mouth it was so big.

His shock didn’t wear off until he noticed that his aunt was taking deep gasping breaths, her face still slightly blue from a lack of oxygen from when his dick had grown down her throat. Finally taking in her appearance he noticed the cum stuck to her face, her flushed cheeks and wide eyes making her look like a little slut, and that’s what the voice in his mind was telling him, that she was a slut, that she was his slut and he would have her any way he wanted.

And it was this voice that won in the end, with the sight of his cum dripping off her face Harry quickly became rock hard again. “Now Aunt you’re going to do as I say, and take off all your clothes so I can see just how bad a body you have before I fuck you.”

“No! I won’t. Stop please, Harry. I promise I won’t tell Vernon, just please don’t make me do that.” She plead, using his name hoping that that would calm him down.

It didn’t work. “So it’s Harry now is it? What happened to boy? No I think I am going to enjoy fucking you. Now take off your clothes.” He said the last part in a deep commanding voice.

Pleading with him to stop her body never-the-less complied with his demands and soon she was completely naked standing in front of him. “Hmm, you certainly have let yourself go Aunt. You used to have a nice body, if only you had been able to keep it fucking you might actually be enjoyable. Your breasts look like they used to be big and firm, I’ll bet Dudley loved to suck on those when he was a baby.”

To both of their surprise her breasts suddenly started filling out returning to the state they were in her prime. Petunia gasped while Harry was trying to figure out what was happening, he thought that he might be a metamorphmagus but that only allowed you to change your own body not someone elses. Not knowing what else to do Harry decided to see if he could control it. His Aunt had a dull brown hair atop a pinched face a neck that was too long. Her breasts were now very nice but he wanted them bigger and he could see her ribs and hip bones sticking out from her skin she was so skinny.

Starting with the hair he tried to make it darker and fuller so that it would bounce when she walked, to his surprise it worked and her hair changed to suit his wants. Gaining confidence Harry concentrated on what he wanted the rest of her body to look like and began changing her so that she matched.

It wasn’t until her breasts grew from a firm b-cup to a large c and then to an even bigger d-cup. She almost fell over from the added weight to her chest. Looking down she began to take stock of her new body. She now had bigger breasts that didn’t sag at all, a tight flat stomach, it looked like she had gained 10 pounds over her entire body, making her look like one of the models in the magazines she always read. Dropping her hands to her pussy she found that it was bare, moving her hands to her ass she found that it had also changed, filling out and becoming rounded. All in all she decided that her body now looked like that of any model she would find gracing the cover of any magazine or movie. She loved it. And had it been any other man but her nephew who had given it to her she would have gladly fucked him until he couldn’t walk.

However she found she had no control over her actions and walked back over to her nephew who was now sitting up on the bed gazing at her in lust. Putting her hands on his chest she gently pushed him back so that he was laying down again his cock jutting straight into the air. Once more she climbed on top of him and placed his penis at the entrance to her pussy and slowly guided him in.

As he pushed farther into her she felt as if she was being split apart, she had never felt so full, not even from the dildos she used on herself after Vernon had gone to sleep from their lovemaking. He was only eight inches into her when he felt that he couldn’t go any farther. At that point he felt her begin to bounce on top of him taking him almost all the way out before dropping back on to him. She continued to do this, moaning involuntarily as she felt herself become more aroused than ever before all the time taking a little bit more into her pussy until she felt something move inside her and she suddenly dropped the last four inches and was now taking his cock in her completely.

“Merlin Aunt! You’re pussy feels so good around my cock. I’ll bet this is better than Vernon ever did.”

His comments made her furious, and while normally she would have stopped his control over her wouldn’t let her and so she took out her anger by bouncing on him faster.

“Oh…Oh…That feels so good Aunt. Yes faster, faster fuck me harder, take my cock up your slutty pussy.” His words only served to make her angrier causing her to bounce even faster until she felt herself cum, her pussy clamping down on his cock squeezing it until the point that it almost hurt.

It was at that point that he emptied his balls into her womb. “Ah aunt that was wonderful!” Harry praised.

Her face a mask of disgust she raised herself off him. She was disgusted at both herself and her nephew, but at least now her body looked better than it ever had, even better than her dead sister’s. As she turned to leave the room she felt the changes to her body begin to fade.

Spinning around in panic she yelled “Just what the hell do you think your doing boy, put me back the way I was.”

Smirking Harry replied, “I am.”

“No! Back to how I was when you were fucking me, it’s the least you could do for making me have sex with you.”

“Oh so you liked the changes, I thought you didn’t abide by any of my freakishness.” He taunted.

“I don’t but-” she was spluttering now trying to come up with a reason for wanting to keep her body.

“Well if you want to keep that body, I guess you can. However there is a price, to keep it you have to strip naked every day as soon as Vernon and Dudley leave the house and let me fuck you until I leave in a week. If you do when I leave I’ll leave the changes.”

She was outraged but desperately wanted to keep her new body. And as she thought about it, she had already fucked him once what was a few more times. He would only be here for a week and then she would never have to see him again and even though she would never admit it he was a good fuck, with a dick as big as his he made her feel more pleasure than she ever thought possible.

“Fine.” She agreed grudgingly.

Harry smiled, he hadn’t expected her to go for it but was pleased that she had. Waving his hand at her he collapsed onto the bed forcing the changes back onto her body. He was going to enjoy her greatly in the coming days.
