- Okay… Just a little bit more of this and… Voila! – Said a raven-haired man happily.

He was placing some materials in a hot cauldron, and the liquid that was green at first little by little started to change, the liquid got as many colors as the rainbow, until it finally stopped, of course, it wasn't that simple, the thing let out a strange sound but it didn't last for too long and when it finally stopped, he looked at the liquid once again and he smirked triumphantly, the thing looked just like water.

But suddenly, the room that he was using to experiment was opened, and a bunch of girls walked straight into the room, they were dressed in just their panties and small blouses, the older man couldn't help but blush at the sight, the girls were too careless, but they didn't care about covering their bodies right now, their wands were raised and they looked eager to battle whoever dared to attack their master.

- What happened here master, are you okay? – Asked the eldest one in the group, Victoire, she was using a white thong and a blue blouse.

- It's all okay girls, don't worry but put some clothes on please! – Harry told them desperately while he looked at anywhere but them.

The girls suddenly conjured a spell and then, they were clothed once again.

- What happened here, daddy? – Asked a young redhead, as she walked towards where the older man was, he was composing himself little by little.

The other girls didn't waste time and quickly joined him too, they were worried by what the older man just did, they were sleeping peacefully, it was past midnight and he was still working.

- Don't worry, this was a normal reaction for the potion I was brewing Lils, don't worry, I'm fine – Harry said calmly.

- Is this the thing you've been working on for months? – Asked Rose, another redhead.

- Yes, as you know I need to hurry in getting this thing ready… The government is funding this project, they want quick results – Harry said before he sighed.

- What is it about master? – Dominique asked, worried about the current state of her teacher.

Harry wiped some sweat from his forehead while he thought about what to say to his students and daughter, he has been waiting for it for a long time, but it seems like he was ready to tell them about his current project.

- Well, I'm working on a better version of truth potion – Harry answered calmly and the rest gasped.

That is not an easy potion to make, it requires tons of rare materials and there was also another essential factor on the brewing of this potion, the time, but it seems like Harry has made some upgrades.

- Why is this different from the one in the original recipe? – Asked Victoire with a soft smile on her face as she stared directly at Harry's eyes.

The older man smiled, he liked to teach stuff and he liked to talk about himself, so this was the perfect chance to do both of these things.

- I'm glad you asked Tori – Harry said cheerfully before he gave them his back to open the curtains, he was feeling the temperature rising little by little.

Spring had just started so, the temperature was slowly rising after the winter, outside, there was a clear sky but it seems like it was close to dawn.

- As you know, to brew the typical truth potion you need to collect some rare materials and you also need some special and controlled conditions to do it – Harry said and his students nodded – One of those things it was the time… I managed to replace a key material that it's not as strong as the previous one but it's easier to get – Harry confessed and everyone gasped – But that's not all, it takes less time to brew and thanks to the replacement of that material, it's easier to brew more truth potions – They clapped at him and Harry couldn't help but blush – But haven't finished yet, there's another perk to this… To get the full effect of the previous potion you need just one drop, that's all! – Harry said enthusiastically and the girls couldn't help but celebrate with him.

Well, all girls excepting Dominique, she was quite obsessed with potions, this sounded too good to be true for the younger veela and she was starting to think that this was amazing, but she knew that there was something hidden behind it, Harry was surprised to see Dominique so serious.

- Hey Domi… What do you think about it? You're the potions expert after all – Harry said calmly.

Dominique remained in silence for a while, she was trying to think in the best way to formulate one question that was invading her head right now, she caressed her chin before she looked directly at Harry's eyes.

- Well, I must admit that all this work you've done is unbelievable master but… - She started – There must be something negative about it, right? Because it just sounds too good to be true – Dominique said calmly and Harry stared directly at her eyes for a while.

The older man closed his eyes and sighed, the other girls were a little angry at Dominique, they thought that she had offended their master who told them enthusiastically about his work, but he surprised them once he opened his eyes, he smiled at the younger veela.

- I'm glad you asked that Domi… You have a great future, as an investigator you always need to ask whatever new thing you and most of all, you need to do it when something sounds too good to be true because if that's how it sounds then it's probably fake! – Harry said before he smirked at them.

Dominique blushed, hearing her master say something so nice to her made her feel so warm, she never heard her father saying something like that to her in the past, so, hearing Harry talking about her like that made her feel proud and the rest of the girls in the room were a little jealous of the praise that Dominique received.

- Yes, just like Dominique said, this sounds too good to be true and that's because it is, but don't worry, the downside of this it's not that bad as you might think – Harry said calmly – In the past, the truth potion had an incredible effect of almost half an hour per one hundred milliliters – Harry confessed and they nodded – As I said before, with just one drop you have the same effects for less than a minute and a half, but that's all the effect that you need to get a confession from a criminal – Harry said calmly – And before you ask, no, you can't use more than one drop to increase the effects, I proved with myself and the only thing that adding more drops does is that it increases the effect for a couple of seconds but it's not worth using it like that, it's better if it's used little by little – Harry confessed and the women nodded.

The girls started to discuss with each other about what they had just heard, they were still astonished about the information they got, all four of them were thinking about what to do if they got a drop, especially Victoire, she was already planning what to do with just one drop of this potion.

- Don't worry well, I'll give you a class soon about this new variety and I'll even teach you how to make it, you just need to wait some weeks, this needs to get approved by the ministry first – Harry said before he placed the pot lid, he was ready to save the ingredients.

- Well, look at the hour… Girls, you should get back to bed, your day is going to start soon! – Harry said and the girls nodded, except for one, Victoire.

- Master, do you want me to help you save all the stuff and clean this mess? – Asked the veela with a slight smirk on her face.

The other girls looked at the older girl with murderous eyes, but Victoire didn't care about them at the moment, Harry smiled and accepted her proposal.

- You should get back to your room girls… Don't worry… I'll help master – Victoire said to her cousins and sister before slamming the door to leave them outside.

The girls were too angry right now to say anything, and they had some reasons to feel like that, the truth is that all four of them were crushing on Harry, even his own daughter was feeling like that, but Victoire was convinced that she was one that should be with Harry and each one had their own reasons to believe that they were the chosen ones to take that post, after all, the older man is attractive and successful, he's probably the most desired bachelor in the whole wizarding world and these girls aren't stupid, they know too well about Harry and his sex abilities, they heard some rumors about it, so, it was tempting for them to take the older man with them.

Still, the girls decided to get back to their rooms, they expected that Victoire wouldn't try anything weird, they all made a strange pact, they could show their charms to Harry, but if they try something beyond that, something bad might happen to the one who breaks that rule, or at least that's what they're expecting after they signed a magical contract to avoid that one of them would break a rule.

Victoire smiled triumphantly, she decided to help Harry to get the materials where they belonged, and she also helped him to clean his workplace, but she wasn't wasting any time, Victoire was taking advantage of any chance she had to show off her amazing figure at the older man.

She managed to show off her rear and long legs when Harry decided to look back at her, the younger woman was happy to do it, she was convinced that she was going to be one that was going to win Harry's heart over her cousins and sister, she didn't hate them, she just didn't saw them as great rivals.

- That's all for now Tori, don't worry… I'm going to use this place later so, it doesn't have to shine – Harry told the younger woman and they were about to get out of the room.

And while Harry made her face his back, she saw a chance to get something that she wanted, she did it at an incredible speed using her wand.

- Tori, are you coming? – Asked the older man startling the younger woman and she nodded furiously.

She ran as fast as she could towards her master who smiled at her, they walked together and Tori felt in heaven for doing it, she didn't mind if she could do this for the rest of their lives, as husband and wife of course.

Harry and Victoire said their goodbyes and they went straight to their rooms to rest until it was finally time to start their day, but once Victoire opened the door, she was surprised to find out her cousins and sister already waiting for her.

- Hey… What are you doing here? Not that I mind though – Victoire said calmly before she decided to get rid of her clothes to get on her underwear once again.

- Don't try to lie to us Victoire… We know that you did something with him! – Complained Lily.

- I don't know what you're talking about dear cousin – Tori tried to fake innocence.

The girls didn't believe in her words, but they didn't have proof to say that Victoire did something with Harry, they decided to get out and get back to their rooms but not before threatening the veela who just sighed at the behavior of her relatives.

The rest of the occupants managed to rest until breakfast, but today there was a surprise, it wasn't Harry who was making breakfast, it was Victoire.

- Oh, Master… Girls, please sit, I'll serve you breakfast – Victoire said before she placed a plate full of pancakes.

Harry smiled and quickly did as he was being told, the girls were a little skeptical about this, but still, they joined the bed.

- Please enjoy it Harry – Victoire said before she placed a glass full of orange juice.

It didn't take too long for the older veela to join the table to eat with the rest, Harry smiled, he liked being treated like this, a long time has happened since the last time a woman has ever done something like this for him, Harry decided to take a sip of the drink, he felt that it was different but he liked the taste until his expression suddenly changed.

- Okay… This is enough… I can't do this anymore – Victoire said before she walked towards where Harry was.

She decided to sit on his lap surprising everyone, she was so honest with her movements.

- W-What are you doing Victoire? Stop her dad! – Lily complained.

- Don't worry Lils, I like when she does this – Harry confessed surprising everyone.

- Oh, you flatter me, master… Do you like me that much to sleep with me? – Asked Tori with a slight smirk on her face.

The older man nodded furiously, he was acting too weird this morning, Rose started to think, this morning was too weird for her, the fact that Victoire was making breakfast was the first indication that something wrong was going on and then, Rose's eyes widened, she started at the orange juice that the older veela handed at Harry and then she stared directly at Victoire.

- What did you put on his juice? – Asked Rose surprising everyone, except Harry who seemed to be in a calm state right now.

- I don't know what you're talking about… - Victoire tried to fake her innocence.

- Bullshit… You put some truth potion that you got when you helped him to clean! – Rose said and the rest of the girls looked at Victoire with their eyes as wide as they could.

- So… Dad's being honest right now, uh? – Asked Lily seriously.

Victoire was starting to get worried, her plan has been discovered.

- Dad… Do you find me attractive? – Asked Lily while blushing.

- Forget about it, Lily… He's your father, you prefer me, right? – Rose asked with a sweet smile on her face.

- Forget it you two… Harry likes them blonde… - Dominque looked at Rose and Lily – And young! – Dominique added with a slight smirk as she looked at her older sister.

And then, a fight started in the kitchen, all the girls were discussing who was the best for Harry, the older man just smiled and chuckled at them.

- Don't worry girls… I like you all the same – He confessed – You're all attractive, I fantasize about you every night… Especially you, Lily, you remind me of the two most attractive women I've ever been in love with… My mother and your mother! – Harry confessed surprising the girls.

And just after he said this, the effect of the potion disappeared, he looked at the girls with guilty while they just smirked at him, the older man couldn't help but gulp, he wasn't ready for what was about to happen, that night Harry had more sex than he can recall.
