So, my english is horrible and that's one of the reasons I write this FF, to get better at it. So if you have any suggestions, let me know in the Reviews. Anyways, I hope you enjoy. Chapter 1

A shadowy figure made it’s way down to the Hufflepuff common rooms. The sounds of students filling the great hall could be heard even in this part of the castle. Right before the Hufflepuff basement, he figure turned to a painting and tickled the pear that was seen on it. The pear laughed and squirmed and turned into a green door-knob.
The figure entered the kitchens and swiftly made it’s way to the food, that stood there, ready to be summoned. The house elves took no notice of what was happening behind them.
After a short search, the figure found what it was looking for, the pumpkin-juice kegs. The figure longed into it’s robe to reveal a small vial, containing a translucent liquid. Carefully it dropped a few drops in every keg and quickly left the kitchen. The deed was done. Now all that was left was to spectate the results.

It was looking to be another, very weird school year for Harry Potter and his friends. First, the Hogwarts-Express got attacked by a dementor, and they where only saved by the new DADA-teacher, then Harry was left with a strange, tingling feeling in his belly after the feast. He asked Ron and Hermione and they also experienced the weird sensation. Everyone seemed to feel it, but since it wasn’t too unpleasant, no one seemed to care. But in Harrys experience, everything unusual was suspicious. The golden trio made it’s way up to the Gryffindor common rooms, where Ron and Harry parted ways with Hermione and made their way up to the boys-dorms. They quickly emptied their trunks that where dropped for them and undressed for bed. Noone noticed that they all forgot to wear their pajamas and no one cared to see each other naked, even if that would’ve been a no-go in the previous years. The same situation repeated itself in the rest of the castle.

A knock was heard in the divination classroom and a naked Sybill Trelawney, who was stretched out on a small mountain of pillows answered with a jawn.
Albus Dumbledore climbed out of the trapdoor that acted as the entrance to the classroom.
“I think it was a success, Albus.” Said the teacher, whilst offering a pillow for the headmaster.
After the old man had sat down, he started to laugh. “Yes, indeed. Only a weak compulsion and everyone drank the pumpkin-juice, even the teachers and those who usually dislike it.”
“Aaah, I can’t wait to see the results, I hope it’s as successful as last time.” She said with a dreamy voice.
“I’d bet on it. Our previous attempts had no negative consequences, thankfully.” Said the headmaster with a smirk.
Trelawney started to giggle “Yea, those poor guys had to keep the secret for seven whole years. Anyways, the formula of the potion was changed, as you told me in our last meeting, so has anything changed?”
Dumbledore shook his head. “Not really, the students should accustom easier to the change now, it was quite the turmoil last time.” His eyes drifted away while he remembered the first school day, exactly seven years go.
It was the second time Albus and Sybill had started their little ‘experiment’, as they liked to call it. Ever since Albus had found the ‘Potion of the romans’ or the ‘Potion of lowered inhibitions’, he had fantasized about a boarding school where no student had any inhibitions at all.
The potion got it’s name from the very unbridled lifestyle of the ancient romans. They didn’t care about nudity, open display of sexuality or sexual orientation. But that lifestyle died with the demise of the roman empire, luckily the potion replicated it fairly well.
Sybill Trelawney was like a god-sent gift. She was the only applicant for the position as divination-professor and they instantly got along. Over the first year they got closer and eventually engaged in a relationship. After a while, Albus had told her about his fantasy and she was enthusiastic, so they started developing a plan of letting that fantasy become reality. The potion was the foundation of the project, they only would have to make sure every student and teacher took a good amount of the potion. Then a charm was cast on the students that prevented them from telling their parents, as well as disable the potion at the end of the year. The students would have the option of either having the specific memories altered or take a magically binding vow to not tell anyone that did not participate in the experiment.
Of course, they knew that what they where doing was highly illegal and unethical, but they also thought that it would create a stronger bond between everyone. And it worked.
The first day of the second time they did their experiment, something went slightly wrong. The potion worked too quickly and that resulted into a chaos on the very first day, where the breakfast basically turned into an orgy, before the SexEd-lessons could be announced.
Albus and Sybill had agreed to teach each student in sexual education, so no unwanted pregnancies where possible. The lessons also included basic sexual etiquette, so the student knew that rape etc. where a no-go.
“Good memories.”
“Indeed.”
“Well, we’ll see tomorrow. It shouldn’t be too noticeable, the potion is only taking effect. Good night, Sybill.” With a last kiss, the headmaster descended down the trapdoor.
The professor sighed. Their sexual relationship had stopped once the headmaster had gotten severe erectile dysfunctions. Another good reason for the experiment. She was looking forward to it.

The breakfast in the next day started just as usual. Harry was still struggling to keep his eyes open, Ron was still eating in a shocking speed and Hermione still reviewed the topics of their first lessons. Yet something felt off. Maybe it was the unusually high amount of kissing couples or the noise that was present around them. Normally, breakfast was fairly quiet, only interrupted by the post-owls.
Harry noticed that Ginny was approaching and turned to greet her, but he was dumbstruck when he saw what she was wearing. Or what she wasn’t. Ginny wore a black miniskirt and a red tanktop. You could clearly tell that she wasn’t wearing a bra so Harry could clearly see her young b-cub breast with her nipple poking out. Weirdly enough though, Harry had no intentions of pointing that out and wasn’t afraid of looking. He wasn’t the only one either, most of the boys around him and even Ron where staring at her and she seemed to greatly enjoy it.
Then, Harry looked around the hall and noticed that the same thing occurred on the other tables. A blonde girl with dreamy eyes on the Ravenclaw table seemed to have forgotten her clothes completely, only wearing her school robe, that revealed more than it hid. Some girls only wore their bras and nothing over it. A lot of boys actually sat there with boxers on instead of pants. How didn’t he notice this? He was one of the first in the hall… everything seemed… normal. And maybe it was normal. Harry decided to ignore it, but that proved to be difficult, since he had a raging boner in his pants. Oh well.
The rest of the day developed even weirder. Couples could be seen on the floors, openly fondling each other, even having their hands in each others robes, moaning loudly. The professors didn’t seem to take notice at all. Snape even showed up to his potions class in a dressing gown, a cup of coffee in his hand. He also seemed a lot more relaxed that he usually was, much to the delight of Harry, who wasn’t yelled at once.
During lunch, the next, unusual thing occurred. The headmaster stood and with a cough, the hall went silent.
“I have a special announcement to make. Some of you might have noticed that you have two open lessons in your class schedule. This is by no means a free period.” Collective moans echo through the hall until the headmaster raised a hand, which silenced the hall again. “No free period, but each class will have separate ‘Sexual Education’-classes with Professor Trelawney. First year on Monday, Second year on Tuesday, all the way to Seventh year on Sunday.” Shocked yells, specially from the seventh years. “The staff has deemed this step to be necessary. Especially Purebloods have very limited education in this subject, so we will counteract it this way. Now after that, enjoy the rest of your lunch.” With that he sat down and the hall erupted into whispering.
“What is that about? I know everything about sex!” claimed Ron, who seemed slightly insulted, since he was a pureblood.
“Are you sure? Aren’t you still a virgin?” answered Harry.
“Sure, but there are other ways of… finding out.” Ron said.
“Such as? I don’t think they sell those kinds of books to kids like us.” Asked Harry confused. He personally knew only the basics, having read about it in his old muggle-schoolbooks.
“Let’s just say that the burrow is very badly soundproofed.”
“Oh.”
“Yea.”
“So we’re having SexEd on Wednesday?” asked Hermione, who had been ignoring their conversation.
“I think so, right after lunch, like the first year now.” Answered Harry, looking at his magically updated class schedule.
“But Professor Trelawney? Will she predict our future sex-life?” asked Hermione and giggled.
“Probably.”

The ‘highlight’ of the day happened in the evening. The trio was in the library, working on the first homework they’d gotten, when a half-naked Oliver Wood and an equally naked Angelina Johnson stumbled from a dark rack bay into the light, where Oliver laid Angelina on one of the tables that where placed around the learning students. Being only a few meters, they could clearly see everything that was going on.
Oliver took one of Angelinas already naked breast into his hand, vigorously fondling it, and took her other nipple in his mouth. Angelina pushed her body onto Oliver’s caressing mount and moaned loudly.
Oliver, encouraged by her reaction, moved his lips lover, pulling her knickers down and licking over her already dripping wet slit, which caused her to scream even louder.
Harry, Ron and Hermione couldn’t help but watch the scene right next to them. The couple seemed to take no notice of them and if they did, they didn’t care. Harry and Ron felt the bulge in their pants swell, regretting that they even put them on. Even Hermione started to get a little wet.
When Oliver finally pulled his boxers down to reveal a thick and long penis, Hermione couldn’t help but shove a hand down her skirt.
At the same time, Harry and Ron both seemed to lose the rest of their inhibitions and both unbuckled their pants and pulled out their dicks. They where nowhere near as big as Olivers, but for their age, they where fairly well equipped.
They started stroking their completely erect cocks when Oliver entered Angelina in one hard thrust, which caused the girl to scream in pain and pleasure. With a wild, animalistic force, Oliver pulled his big member out and shoved it in even harder, increasing his speed steadily. He reached down to her crotch and started rubbing her clit, causing her so squirm in pleasure. Oliver was grunting while he slapped against her ass, while he again increasing his speed.
The three watching teenagers where now openly masturbating, completely forgetting that they where in a public library.
Angelinas screams got louder and with a last “Oliver!!” she contracted on the table, screaming in pure bliss. Oliver pulled out his throbbing dick and released some big streams of semen onto Angelinas breasts, belly and crotch. In this moment, the trio also came, with the two boys also ejaculation mostly in their hands, but some of it flew onto a heavy breathing Hermione, who did not seem to mind in the slightest. She scooped up the semen with her hand and took a testing lick.
“Wow you guys taste good!” she said with a suggestive smile, that almost caused the boys to get hard again.
Oliver oulled up his boxers while Angelina fetched her robe from behind one of the shelves, wrapping it around her naked and sweaty body. They exited the library with a last smile to the trio.
“So what is happening right now. It seems like no one has any inhibitions anymore.” Harry noted.
“I guess you are right… although I barely notice any changes. I’m just not ashamed anymore.” Answered Hermione. “Look, you guys even still have your dicks out, that would’ve never happened last year.”
“Maybe it has something to do with the new SexEd class?” suggested Ron.
“You are right, it can’t be a coincidence.” Hermione agreed.
“We’ll just have to wait until Wednesday.”
“I guess.”
