Prompt #21: Foxxay/Harry Potter AU. Cordelia Goode is the severe, serious potions professor, while Misty Day is the cheerful and flirtatious herbology teacher.

A/N - For non-potterhead readers: Gillyweed is a plant. The potions classroom is placed on the underground dungeons of the castle, where its also placed the Slytherin's common room.

The dudgeons weren't Cordelia's favorite place in the castle, but they were where the potions classroom and, as the teacher of the subject, she obviously had to go through them. The dark bricks of the walls were covered with a thin wet layer, product of being underground. She thanked God that the class was almost finished and she wouldn't have to stay there for at least another two hours. The last sand grain of the hourglass fell, indicating that the class was finished, and the Slytherin and Ravenclaw students started to march out of the classroom.

"Goodbye, professor Goode." the prefect of one of the houses murmured in a flirtatious way with a smile before leaving her alone. It wasn't a strange thing having students giving her smiles and making inappropriate comments when they thought she couldn't hear, after all she was one of the only two teachers who weren't in their eighties or dead. Cordelia quickly started to pick up her things and vanished the content of the cauldrons with a quick wand movement, not seeing at first the younger woman who stood by the door with a basket on her hands.

"Hello, professor Day." the potioneer said with normality when she noticed the gold-haired woman. She was wearing a brown robe with a black floral pattern, stained with dirt after being working on the greenhouse all day. "Come in, please."

"Good afternoon, professor Goode." the younger woman answered with a cheerful voice as she walked to the teacher. "Ugh, this classroom stinks, what the hell happened?"

"One of my students seems to have a particular proclivity for pyrotechnics." the woman replied with a smirk. "I mean, Wiggenweld Potion is not that hard to craft!"

"Well, not everyone is a master potioneer." the Herbology teacher responded, making Cordelia let out a giggle.

"And not everyone has excellent skills at Herbology, so I think it's a tie. What have you got there?"

"Oh, it's the gillyweed you asked for. Where shall I put it?" she asked, looking around her.

"Oh, um... do you mind to come with me to the storage room? I prefer to leave it there. After all, I won't need it until tomorrow and I don't want my students to steal it when I'm not looking."

"Oh, c'mon, let them have a little bit of fun."

"If by having fun you mean stealing my ingredients so they can go to the lake and swim on it, no, I won't let them. That's irresponsible, immature and characteristic of students with no common sense. Also, who knows what lives in there!" the potions teacher exclaimed as they made their way upstairs to the school's hall.

"Some grindylows, merpeople, a giant squid with its family and tons of frogs."

"How do you even know that?"

"I was an irresponsible and immature teenager once too. Also, skinny dipping in the lake at midnight is quite relaxing." she stated, winking to the woman as they passed a group of Slytherins who tried to enter their common room with an incorrect password. "The password is Bloody Baron." she informed them with a serious tone.

"Thank you, professor Goode." they chanted.

"Try not to forget it again." she replied as the students entered in the corridor. She started walking again, closely followed by the curl-haired woman.

"You should try it someday." Misty said.

"What?"

"Skinny dipping."

"I doubt it."

"Why are you always so serious?" the younger woman asked.

"Because it's my job. And yours too." Cordelia reprimanded her.

"That doesn't mean we cannot have fun, professor Goode." the herbologist said, winking to the woman.

"What you don't have is common sense. Flirting with me in the middle of the hall, where anyone could hear you?" she said in a whisper.

"Oh, you're so boring, professor Goode. It's impossible to have fun with you."

"I don't think you and I have the same concept of fun, professor Day."

"Do you have any classes now?" the teacher asked.

"No." the potioneer replied, unlocking her storage room and entering, closing the door after them. The small space was full of shelves and containers with herbs and ingredients of all kinds, and when Cordelia placed the gillyweed on its place and turned to get out of the room, she found herself trapped between the shelf and the other teacher. "Why do you ask?" she questioned, looking to the other woman's eyes with a confused gaze.

"Because I've really missed you." the taller woman whispered before cupping her face with her soft hands and leaning in to kiss the potioneer passionately. The woman's hands quickly ran to the other teacher's curly hair, pulling her closer as she deepened the kiss. After some seconds they pulled apart, the potions teacher letting out a soft giggle.

"I've missed you too."

"Then what do you think about going to the lake tonight?"

"I'm not going to skinny dip, Misty."

"I was gonna say to relax a little..."

"Oh."

"Is that a yes?"

"Maybe."
