Author Note:

OfficerDonNZ: Yeah the mental imagery writing this was disturbing. I'm a visual writer and see the scene as i write. Lets suffice to say much mead was drunk after this...If you or someone else wants to have a go off this or any other idea have at it. My ego is not fragile enough to get bent about that. A lot of my ideas are the same basic story ideas floating around here just coming at them from a different angle.

N0wa5t3R: No problem. (a) I should have put them in separate chapters at the start but got lazy and didn't really expect the positive feedback. (b) yeah i am enjoying these little shorts as I can sit and think about how the story goes while I go mow or do some of my other work and then when i sit down at the computer its already pretty much written and all i have to do is type it up and make sure that its at least internally consistant, I've not misspelled things too horribly and that I've not taken a right turn into too dark. That's why I have my wife give a go over these before they get approved to go up on the web.

TIMEKEEPER: No problem. I'm having fun and enjoying this. So as long as the fun holds out the stories keep coming.

One of the big rules I've given myself for these though is that they stay mostly upbeat and fun. None of the changes would be so crippling or debilitative that she could not enjoy some form of normal lifestyle. None of the changes would be such that it woudl prevent her and Harry falling in love and having a family eventually. Also I've tried to keep them somewhat if not in a canon compliant way at least driving down the next lane over from canon as much as possible. That's not so much a rule as a guideline though.

=======
This one is Hermione gets a Libido enhancer developed but it works on everyone around her not her. Sort of like a Veela allure. It could have gone dark and very very nasty but I tried to keep it mostly funny glossing over some of the more dark points this kind of power would cause. This is not the time or place for that. anyhow if this idea isn't good I'm sure I'll come up with another one eventually. between my wife and some of you on here as wella s my own busted brain I'm getting a list going. lol.

September 1st 1994

Harry and Ron were chatting with Ginny when they saw Hermione come through the barrier onto 9 and ¾. She must have been running very late as the Weasley's had been early and still among the last to board the train.

She approached them carefully like she wasn't sure how they were going to behave. She came up and stopped a few feet away before edging closer.

"Hey Hermione. Are you feeling better?" Harry asked in concern knowing she had missed the World Cup because of some illness.

"Uh yeah. I'm fine Harry. How are you?"

"Good." Then he noticed Ron and Ginny were both staring at Hermione with goofy grins. Ginny occasionally licking her lips. "Although I have no idea what is going on with these two."

"I do I think. C'mon we better get a compartment." She said heading for the train with Ron and Ginny trailing her like hungry dogs. Ron was actually starting to drool a little bit.

When they entered the compartment Hermione opened the window and tried to stay as far from Ron and Ginny as possible. Putting Harry between herself and them.

"Guys what's going on." harry said feeling like he was facing some of Aunt Marge's dogs again.

"Have you ever noticed how beautiful Hermione is?" Ron hummed staring at her.

"Really she has grown up nice. Filled out those curves." Ginny growled hungrily.

"Yeah can I rub your breasts Hermione? I'd really like to." Ron was sighing at her holding his hands out.

Harry pushed Ron back "Hey have a bit of respect man. She's not a piece of meat to paw all over."
"Really dipshit brother. A woman likes to be treated well. I mean Hermione knows the best one to please a girl is another girl. Right Hermione. You'd let me please you right?" She said batting her eyelashes and unbuttoning the top two buttons of her shirt.

"Oh shit." Hermione sighed from behind Harry. He noticed out of the corner of his eyes she was wriggling out of her knickers which she threw at Ron's face. Harry was confused by that but actually became scared when Ginny growled and launched herself on Ron. "Gimmie those. Their mine."

"No she gave them to me."

Hermione grabbed Harry's arm and dragged him out of the compartment before the Weasleys could tear into him in the middle of their fight.

"Stupid hottest day of the year and dad's AC has to break. Mom's been bugging him for two years to get rid of that stupid junk heap and get a Range Rover. But no its a classic car he says. So no I get all sweaty and bothered. Oh geez."

She pushed Harry into an empty compartment at the very end of the train. "Sorry harry. I've got to tell you something. I hope you understand."
"Hermione I'll understand a lot I have something I wanted to tell you too."
She went over and opened the window and then sat across from him. "Okay Harry I'll let you go first if you want."
Harry started blushing then ran his hand through his hair, "I like you hermione and I'd like to be your boyfriend if you'll have me." He stammered out.

Hermioen rocked back in surprise before shaking her head. "Oh Harry what brought this on."
"The World Cup. After seeing the Death Eaters attack the people there and hurt people I thought about you and I realized I have feelings for you. I tried to write a letter but I chickened out."
Her expression changed from sadness to a slight bit of hope, "So this isn't something that just came up in the last couple of minutes?"

"No I've been thinking about this all summer. I even tried talking to Ginny about it knowing how she feels about me. She is okay with things. She kinda realizes that her crush on me was more the boy who lived and not really me."
"And you're not having a physical reaction to me right now?"
"Uh no more than usual.

"You don't have an erection? Want to get on your knees and sexually pleasure me?"

Harry blushed, "Uh well I have a sorta stiffie. But that happens around you a lot. Especially last year. And uh I guess. Uh. WHY are you asking me this?"

Hermione laughed then moved to sit beside Harry. "I'm going to do something rather odd but I want you to be honest with me when I ask you a question afterwards alright?"

"Alright."

She pulled the curtains on the doors then sat down again after locking the door. She reached under her skirt for a moment then taking her fingers waved them under Harry's nose. "What do you smell harry and how do you feel?"

Sniffing her fingers while looking at her oddly he shrugged, "Uh they smell a bit sweaty, kinda musky. Not in a bad way. Kinda like uh. I dunno how to describe it."

"And how do you feel?"

"Okay. I feel okay I guess."

"And no desire to jump me? Tear my clothes of for anything?"

Harry frowned at her. "Uh no. I would rather have you as a willing partner for that. I don't like the whole forcing someone thing."
"And you don't have an erection?"

"Well yeah I do now because you keep talking about it. What is going on Hermione and why did Ron and Ginny react like a pair of wild dogs when you threw your knickers at him."
She took a deep breath. "Well thank you Harry. It seems you're immune to this. So that's good. At least there'll be one person I can trust."
"Okay. Start at the beginning please. And use small words I can understand."

"I was sitting talking to mom one night and she was discussing how she wished there was some magical way to get their sex life back the way it used to be. I was a menopausal surprise so that's why I am an only child."

"Oh okay. Your mom and dad don't get it on as much right."

"No they don't. Between working all day and taking care of the house they usually just go to bed. Well there is such a thing as a libido potion. It causes the drinker to become highly aroused."
"Okay sort of like a love potion?"

"No its all about sex with this one. Well I needed to soften the Ginseng paste and I didn't want to wait so I used the microwave oven. That was a rather bad idea."

"Right yeah. Why?"

Sighign she gave him a be patient look. "Because instead of making me aroused when I drank it to test if it worked it seemed to do nothing. I cleaned up and was getting ready to try again when the postman rang. I went to get the post and he started hitting on me. I managed to get the door shut and get rid of him but that was disturbing. A few minutes later the pizza I had ordered showed up. The delivery girl ripped her shirt open and wanted to go down on me."

Harry chuckled. A bit, "Well you seemed to get really popular."

"It's not funny Harry. I had to throw a vase of water on her to get rid of her."

"Sorry yeah I wasn't thinking I guess. But I mean it wears off don't it?"

"No it didn't. By the time mom and dad got home I tried again. This time the ginseng paste had gotten soft normally so the potion was alright. Except I had been working over a hot cauldron all afternoon and was a bit sweaty. Mom and dad both wanted to have sex with me. I managed to convince them to do each other but it was close. Apparently when I put the ginseng paste in the microwave it changed its magical properties enough that when I made the potion it merged with my glands and now I'm stuck giving off pheromones permanently that arouse anyone. Except you."

"Phero what?"

"Pheromones. Sort of like what a dog in heat gives off. You can't consciously smell them but they act on your body to cause a reaction. If I had waved my fingers with that on them under the nose of anyone else, even my own dad they would be so aroused and ready to go that I'd be in serious danger."

"Oh shit. I'm sorry Hermione. Is there anything that can be done?"

"Well if I get hot and sweaty it makes it worse. They gave me a neutralizer body spray I have to use but it wears off after a few hours, and if I get hot and sweaty that weakens it. And if I get aroused myself it makes it a lot worse. Thankfully it won't pass into my breast milk when I get old enough to have babies."

Harry looked at her in confusion.

"They made me lactate to see. Breast's are just large glands."

"Yeah but very nice ones." Harry said trying to make a joke.

"Somehow you're immune. Which I guess is a good thing. Having you as a boyfriend I'll at least know you want me for me." She said ignoring his joke though blushing a little bit.

"Yeah. So uh. Do you wanna go off to the toilet and freshen up?"

"I better before we get to the school. You want to guard the door for me. I'll have to get undressed a bit to ready get the sweat off."

"Yeah can I stop and check on Ron and Ginny first. To make sure they're ok."

"I suppose Harry but I'm going to stay in the corridor. They seemed rather receptive to my scent."

=====xxxxx====

Harry opened the door to the compartment on a scene that would be scarred on his brain for the rest of his life. Entangled in post-coital bliss was a stark naked Ron and Ginny. His mouth slightly open and drooling, his arms around her as she laid atop him. Fortunately they seemed to be too far gone to notice him so he carefully closed the door.

Hermione was looking at him as he shook his head, "They're uh. They're uh resting."

She just raised her eyebrow and went to the loo. Harry stood outside and waved people on saying it was occupied.

======xxxxx=====

Ron and Ginny tried to act like nothing at all had happened on the train ride. Harry stayed close to Hermione to fend off anyone who reacted too strongly to her. Fortunately the breeze from the carriages seemed to keep her cool enough she didn't sweat.

The feast at the great hall was another story though. That many bodies closely packed with hot foods and candles made her worry. Rightfully so because by the end of it she had to slap Neville's hand from her thigh as he smiled at her. Ginny who ahd been sitting across from her had run her foot up Hermione's leg.

Hermione almost ran from the hall followed closely by Harry and a few others before Harry turned and pushed them back.

"Mione are you okay?"
"Yes Harry I just need to freshen up the stupid neutralizer has worn off."
"Perhaps I can be of assistance." The dark deep tones of Professor Snape came from behind them

"Sir?" Hermione asked in fear.

"I am aware of your condition and used a general scent neutralizer of my own creation."

"Oh good."

======xxxxxx=====

Sitting in the Professor's office she held Harry's hand as she clarified what Saint Mungo's had done for her. What she had done to create this. How harry was immune. Snape checked him over and said that he might be able to, with Harry's help, develop a far more powerful neutralizer for her to use.

It took a few days which were nerve racking for Hermione as she would get a following from some of the more susceptible members of the school. She noticed that some reacted stronger than others, but Harry was the only one that was completely immune. The Weasleys were all highly susceptible to her with Ron and Ginny being the most. She could get them to do whatever she wanted just by rubbing her fingers under her arm and then waving them under Ron's nose. She used that to make him do his homework which Harry called cruel.

Soon the Snape developed neutralizer was finished and she was relieved to see that it seemed to last longer and everyone returned to their normal behaviors for the most part. Ron whimpering and following her around to get more of her scent. Madam Pomfrey and Snape declared that due to repeated exposure he was now addicted to her and would have to go through detox to break it.

The tri-wizard tournament came to the school. Fleur the half Veela could still smell Hermione even with the neutralizer because that was partly how Veela attracted people, as well as a magical alluring aura. She gave her some tips and help on how to deal with the attraction the scent caused which Hermione took to heart. They also spent some time together learning a few other secrets of the feminine arts.

Harry made it through the first task rather well. Getting his egg and only being slightly singed. Hermione had been in the crowd and was so worried and scared about him she worked up a fear sweat over whelming even Snape's neutralizer that caused several people sitting near her including Ginny to lose themselves. Having no other choice Hermione shoved her at Ron as she ran back to the castle.

After getting cleaned up and reapplying the neutralizer Hermione congratulated Harry. They

managed to avoid overwhelming the party. Neville and Lavender had become an item after the party in the crowd as she called it. Ginny and Ron again tried to pretend nothing had happened at all between them. Hermione tried not to laugh or react when Ginny and her spoke later, especially when Ginny told her that the stomach troubles she had been having over the last couple of months seemed to be getting over it but that she had begun to put on weight. Hermione tried to ask if she had been sexually active and Ginny denied it with a strange blushing expression.

The Yule Ball was an enjoyable night for Harry and Hermione. Neville and Lavender looked lovely as did Krum and his date Parvati. Ron and Ginny came to the ball together as the fact that she was pregnant by him had been revealed by a howler from home. Apparently she had gone to Madam Pomfrey to find out why she was gaining weight and feeling strange only to discover she was pregnant and a Familia Paternis spell later discovered that Ron was the father. Ginny decided that rather than be shamed by it she was just going to live it and embrace it. Ron though was not as enthusiastic but he did accept responsibility. Hermione felt bad and told them about her changes and what happened.

Ginny forgave her and accepted that the situation was complicated. Ron blew up and blamed Hermione until Ginny dragged him off. Several days later he apologized without explanation although Ginny was standing a few feet behind him when he did so.

The second task found Hermione at the bottom of the lake. The exposure to the water caused the neutralizer to wash off and her normal scent to start filtering through the water. Fortunately as cold as the water was she was not making very much of it.

She was down there long enough though that a small cloud of it was formed around the stage with the hostages. Concentrated into a soup that the Merfolk guarding them had begun to inhale through their gills. Directly taking it into their bloodstream. Horrifically though instead of driving them mad with lust it killed them. Their biology so radically different that human mating pheromones were fatal to them.

By the time Harry arrived there were a dozen or more Merfolk all dead floating slowly to the top of the lake. He couldn't see anything that killed them but he did see Hermione hanging off a post in the middle of a stage. So he grabbed her and moved off dragging her through the water leaving a scent trail.

Krum had changed his head into that of a shark which made his sense of smell a thousand times sharper. He swam straight into the cloud which overwhelmed his senses causing a mad lust rage to form inside him. He ignored the unconscious hostages as they were not the source. He followed the trail.

Harry had just handed Hermione off at the surface and was waiting for the Gillyweed to wear off when Krum attacked. Krum had smelled Hermione on Potter and in his confusion attacked Harry. Harry managed to drive him off and subdue Krum with his virtue intact, but it was a close call.

Harry got out of the water thinking that was another event that would leave him with nightmares. Hermione was wracked with guilt and offered to tell everyone but the nurse said that would not do any good. She was not intentionally doing this to people. Not to mention if the ministry found out she would be classified as a dangerous semi-human like a Veela or a Siren. It would limit Hermione's freedom and ability to function in the wizarding world.

Cedric showed up with the other hostages in a great bit of confusion and arousal as his bubble-head charm had extracted the oxygen from the water but a degree of her scent as well. He and Cho began to congratulate and celebrate on the beach in front of everyone. Parvati confused and Gabrielle underage so safe from plot induced bunnies.

Hermione kept quiet. Ginny had continued to gestate and Lavender was discovered to be pregnant too. Neville did the right thing and promised to marry her. In May Ginny gave birth to a boy which they named Arthur Raymond. Ron was excited that he was healthy and normal looking and no longer a reluctant father, even if it was with his sister. The pure-bloods in the school looked at them with a bit more respect oddly enough.

The third task came and Voldemort returned. Cedric was dead and the school mourned. The summer went well as Harry and Hermione retreated to an island resort causing Harry to not be in Little Whinging when the Dementors came and killed the Dursleys.

Returning to school harry discovered that Cedric had left Cho something to remember him by. Hermione made sure to keep enough of her neutralizer brewed that she would not even have the slightest effect on anyone during the school year.

During the Horcrux hunt she ran out though and Ron had to leave or he would do something wrong. Harry and her were captured by snatchers but she had not bathed or worn her neutralizer for weeks. Her and Harry had been wearing the same clothes for that entire time. So she was reeking of her scent and caused them to become instantly enamored of her. She used this to infiltrate the Malfoy manor where her and harry rescued the prisoners and convinced Bellatrix to retrieve the Horcrux when she fell under Hermione's scent power. Hermione was uncomfortable with seducing so many but harry convinced her it was okay given the war.

They led her prisoner's of lust to the Order of the Phoenix which dealt with them. Although they kept Luna with them as she had a slight resistance to Hermione's scent and wanted to be her girlfriend of her own free will.

At the final battle to help pacify the forces of darkness Harry had Hermione use her scent as a weapon against them. Leading the Death Eaters into traps, blind corridors and off of bridges. Given how much running and sweating she was doing it was not that difficult to get strips of cloth to tie to the various areas.

The battle was still ferocious though even with the tricks Harry was pulling. Some of their friends accidentally got caught in it as Remus, Nymphadora and Professor Sprout had taken time out of the combat for some recreational morale boosting invigoration.

Harry got hit by an AK from an enraged Voldemort. His lack of a nose lending him an immunity to scent based powers. Neville killing the snake though distracted and weakened him enough for a resurrected Harry to plunge his wand in Voldemort's face and yell Bombarda Maxima.

Voldemort's head exploded and the victors tiredly celebrated. Harry and Hermione retiring to a small out of the way village deep in the mountains of Wales. Hermione researched and eventually discovered a neutralizer potion that she only had to drink once a month. This allowed her to return to the wizarding world and help society advance. She eventually became headmaster of Hogwarts and made sure the next generation of muggle-borns understood that magic and muggle ways did not always work well together. Harry by her side always was a proud husband, father and lover, all of his own free will.
