HP: Altair Black. Son of Asmodeus

Mother and daughter arrived at the former's office. It was spacious. There was a large desk, carefully organized with her student's assignments. On the walls, there were several doors leading to the professor's personal laboratories.

"Sit down", ordered the redhead. "Are you sure about what you're doing, Harley?" Both pairs of green eyes began a staring contest.

"Yes", she simply replied.

"Neither your father nor your brother will like your choice. Especially because you won't be the only woman in his life. Also, he is the weakest in his year". Lily's eyes were scrutinizing, searching for reactions in her daughter.

The dark-haired young woman grimaced in disgust at his words.

"He's the best at potions, and he would be in all the other subjects if he had more power", Harley didn't mean to say that he would probably increase his magical power the more he had sex.

"How would you know that?" Lily raised an eyebrow.

"You said it. You usually keep an eye on him. Even if he himself doesn't believe he is capable of standing out too much, you and I know he will once his magical power grows." Her voice was as hard as steel. She didn't want her master power to be questioned.

"You seem sure that his magical power will increase..."

"Of course, he—" she stopped abruptly. Looking at her mother's face, who was smiling at her slip.

"Are you going to be with him because he will become strong?" her mother's question irritated her.

"I would be with him even if he remained weak. I like him since he was weak"

Lily Potter nodded as she looked at her daughter's brave face. The girl was infatuated with Altair. It wasn't a bad thing. Not even unexpected when you know the boy's heritage.

"I won't interfere with your wishes, but it would be better if your relationship remained private, for now", she said in a calmer voice.

"He said the same thing." The girl wasn't happy about hiding it, but she understood. She would be harassed by her brother and Ron.

"A wise young man." Lily nodded. "Now... 'Why didn't he fucked you?'" she asked seriously.

Harley's face turned as red as a tomato as she looked at her mother's face. She looked away.

"He fucked my face if you wanted to know," she said without thinking. Her face turned even redder.

"Was he forcing you to do it?" Lily said seriously. Even if she had affection for the boy, she would not tolerate any harm to her daughter.

"N-no. I... wanted to do it. I liked that he was in control", she stammered in response. Even if it was embarrassing, she didn't want his mother to get the wrong idea about their relationship.

"Sigh! My daughter turned out like this", Lily's voice became distant and melancholic as she seemed to look beyond her daughter's eyes.

"Mama!"

"Okay, okay. If you like those things... if he ever forces you to do something you don't want, kick him in the balls and come see me, mommy will help." Lily's tone was jovial, but Harley knew she was serious. She simply nodded, not wanting to talk about it any further. "Now, follow me to my lab. I will teach you contraceptive potions and those for relaxing muscles. Your legs need the latter, girl... You look like a newborn fawn." She ignore the cry of indignation and enter the first of the three doors.

Harley entered behind her.

"Do you approve of my partner then?" she asked a bit shyly.

"Yes. I just wanted you to be aware of the consequences of your relationship. If you are willing to go through everything. So I will help you... I want you to be happy", 'like I couldn't be,' she finished in his mind.

"Polygamy doesn't bother you? I thought it might be because of Dad." Lily tensed up a bit, but she simply started arranging several cauldrons over the fire and filling them with water for potions.

"Your dad's infidelity was more of an excuse that I managed to use to escape that marriage", Lily searched for the ingredients in a cabinet as she spoke. "If I had divorced without a reason, they could have forbidden me from seeing you and Azalea and Charles. Even then, visits were barely possible", she felt a pair of arms wrap around her waist. She turned around to embrace her daughter in her arms.

"I wish I had lived with you forever. The happiest moments I have are from your visits. In all the others. It was just me and Azalea watching a show of dad and Charles. I never felt good there. Thank Merlin, my sister didn't turn out as idiotic as they did".

"Harley!" She scolded her weakly. Lily felt her trembling in her embrace. "I'm sorry for leaving you, I thought I could get custody... but..." mother and daughter hug each other.

"That doesn't matter now. I'm an adult and I can live with you, right?" she asked with teary eyes.

The redhead kept silence for a while.

"It's not safe... there are people chasing me", Lily replied with pain in her chest.

"I'll be there to save your ass!" Harley turned to the ingredients and began sorting them.

"You shouldn't use that kind of language with your mother, young lady!" her mother scolded playfully. "I don't had a place right now. I will be looking for one. I can't promess anything."

"You will find one and ultimately create the safest place in the world." Your "maybe" is always better than the "I am sure I will" from James."

"Don't say his name, we are having a good time." Then she handed her a mint gum. "Your breath stinks, by the way. Altair probably removed the fluids outside of you, but not the ones that remained inside."

A moan of horror filled the room before they both started to laugh.
