Amu noticed that Sebastian had been keeping his distance lately, which was fine by her. He even left her homework or self-study practices to do alone - avoiding any proximity. She was sceptical, obviously and cautiously avoided being by herself longer than necessary, but she had to admit she was curious about what caused this change. Amu spoke with Kurosu about this, but Kurosu advised not to ponder, thank the good fortune. However, Amu had to admit that she felt a particular way about everything.

Since Sebastian avoided her like the plague, she was back at Ciel's side. She would attend to him during his meals and occasionally bring him his tea while he was in his study. It made butterflies fly rampant in her stomach, and for some reason, it made her ache and heat up everywhere. Ciel always smiled at her, which made her heart pound, but sometimes her mind would drift back to the times they kissed, which caused a certain kind of fire to fill up in her body, making it hard to breathe.

Right now, she was feeling all of that.

Ciel had kissed her cheek after she brought him his lunch. It was sweet, and Ciel even moved his hand to touch hers but was interrupted by a phone call. He dismissed her monotonously, and Amu hurried away, embarrassed but not unhappy. Once alone, she remembered his lips against her skin and the look in his eye when he tried to gauge her reaction. Amu shivered until she felt that heat take over her senses again. Amu cursed softly and moved her hand to her throat - her insides burning almost.

Amu turns the corner and bumps into Sebastian, who looks stunned at first until he sees the redness in her face and her legs trembling. "What a lewd look you got there."

Amu scowled at him, but the way Sebastian smirked at her with his eyelids lowered made her stomach churn. She had to get to her room.

"Just continue avoiding me already..." Amu tries to walk away, but Sebastian grabs her arm, intending to stop her, but Amu's instincts are too quick.

The pinkette spirals her body so that she locks his neck with her left leg, her right hand gripping his onyx locks as she sits on his shoulders. Sebastian stumbled, surprised by the sudden weight causing Amu's side to hit against the wall painfully. She used her leg to exert more pressure on his throat, and he cursed at his luck.

Tanaka trained her fucking well.

Sebastian turns his head irritably and uses his teeth to tear off a piece of the fabric of her sock before sinking his fangs deeply into the smooth skin of Amu's leg, causing her to lose focus. Amu gasps loudly, the sound of Sebastian drinking her blood filling her ears. Shoulders shaking, she whimpers - the hold on his throat loosening as he sinks his fangs even deeper.

Sebastian smirks against her skin and kisses it tenderly when he has his fill before a dark look crosses his face, and he manoeuvres her body to fall onto the floor. With the reflexes of a cat, Amu manages to bend her body so that she drops to her knees, and Sebastian smirks at this, taking her bubblegum pink hair in his gloved hand.

"Now, this is the perfect position."

Amu frowned at him, confused, until she saw his hand reaching for the zipper of his trousers. Amu shrieked and tried to move away, but Sebastian held her hair firmly. The butler growls, moving his other hand to restrain her, but pushes himself backwards. Sebastian falls on his behind painfully and opens his eyes, seeing Amu with a knife in her hand and half of her pink hair on the floor. Amu's eyes flashed dangerously pink, and Sebastian smirked back at her, his eyes glowing to match hers.

"You are a formidable bitch aren't you?"

Amu glares at him hatefully, "If you touch me again, I will tell Ciel."

Sebastian scoffs in disbelief, "Doubtful."

"What? You think I'm lying?"

Sebastian stands up, brushing the dust off his clothes, "I think you know if you tell the young Master about me, he will find out about our trysts together."

Amu falters, "Y-you forced me!"

"Yet if you hated the way I have been touching you, you would have told him about this a long time ago."

Amu felt tears prickling in her eyes, "No, no! I did not like any of that!"

"Lying to yourself is not doing any favours. Your body has been hurting lately. I have been away for a week, and no one else has touched you in the ways I have, hence why you feel that magma-like heat in you."

Amu's eyes drifted back to its honey-colour, and she blinked at him, "H-how?"

"You are shifting to succubi. Your physiology is changing. Your pheromones nearly drive me insane, so I've avoided you as much as possible."

Amu's lips twitched, unsure of what he was saying until she remembered that the other men in the house had been acting weird lately around her. Snake doesn't stop to converse with her anymore because his snakes tend to appear out of his clothes and try to slither towards her whenever in proximity. Snake would stammer an apology and run off without explaining. Finn would blush heavily and bring her a flower of some sort every day at breakfast, while Bard would ruffle her hair and slap her back playfully at every opportunity. Tanaka has been the exact grandfather-like figure, but she noticed his vulnerability showing more as of late. He has recently opened up more to her, telling her tales of his upbringing.

Completely lost in her thoughts, she did not notice Sebastian had moved to where she was and lifted her onto her feet. Startled, she looked up, but Sebastian had pressed her face to his, kissing her fervently. Amu's tongue feels hot against his, his mouth dominating her easily. She feels her body press against the wall and Sebastian lifting her body to straddle him. She breaks away from him, breathing hard, and Sebastian smirks at her flushed expression.

"I would appreciate it if you would return my advances like you did the first night."

Amu's mouth twitched as if he said something foul and changed the subject. "Why do you like this position so much?"

"Why? You're adorable like this, of course." The pinkette blushes prettily at the compliment, and Sebastian's eyes softened. "Such a sweet expression on your face. What I would give to ravage you and make you moan for me."

Amu turns her face away, embarrassed, "Let me go..."

Sebastian tilts his head, "Why? You're feeling better now, don't you?"

The girl blinks and turns back to him - realising he was right. That painful heat in her belly and throat had gone now. The cloudiness in her head and trembling of her thighs from earlier had stopped, too. Why?

"Amelia. Listen to me. If you keep restraining yourself from indulging in your desires, that heat will overtake your senses, and you may do something drastic to relieve yourself."

Amu shivers at his tone, "Drastic?"

"You may rape someone, forcefully take him to satisfy yourself."

Sebastian smirks amusedly at her pale parlour. "For your sake - let me fuck you."

It was the dark of the night, and the full moon was out. Grell was in his reaper form - crossing out his list. Suddenly, he felt a weight on the roof he was sitting on, so he turned his head, expecting Spears or Knox, but was surprised to see his favourite pinkette there. Amy stands upright so he can see her face, but Grell drops his pencil, recognising her. Amber had cut her silky hair into a gorgeous bob with curtain bangs showcasing her angelic-like facial features. An adorable tiny witch hat stood out on her head. Grell didn't think her eyes could be any more captivating than before. Although part of him was slightly disturbed by how much more she looked like his dead sister with just a change of hairstyle.

He gulps, trying to swallow his nervousness, "Why are you here, little Amy?"

Grell's eyes travelled downward, and his eyes widened even more at her outfit. The pinkette was in a purple corset top and a long, subtle cross-print-black skirt open in the front. The colourful corset top has bright red and purple colours, a peasant halter style, and a padded bodice. Amy's arms were in long, extravagant-looking lace gloves. "A-Amy..."

"Grell, I need help." That pleading tone put aside his anxiety, and he listened patiently to the girl's grievances.

It was much later in the night when Spears had his first introduction with Amelia; for once, he was bashful around a female. He knew logically she was a succubus, but her innocent face enamoured him. Grell took the girl to seek his advice since Spears had previously dealt with the succubi clan, but this girl had the most maiden-like visage that struck him off-guard.

Spears coughed into a fist, trying to regain his composure. "I heard before that succubi drink blood to satiate the hunger."

Amu twitched; she remembered now how much more relaxed Sebastian seemed after he drank her blood. "Human blood?"

Spears shrugged, "From what I understand, those demons drink blood from their partner to prolong the climax.."

Amu groans, covering her face with her hands. "So drinking blood is only to content them to draw out the sex momentarily? But isn't biting someone intimate?!"

Grell couldn't help himself; he grinned. "Well, that is true. I must say biting your partner is sexy."

Spears rolled his eyes, "From what I know, human blood is usually the most filling for them. That's why most succubi have human lovers they own personally, meaning those humans cannot be contracted with other demons, so they can only bond to one demon. It's disrespectful, according to their laws, to share. The disrespected demon has a right to kill if someone trampled over their property."

Amu bit her lip, which meant she couldn't drink from Ciel, and she knew how terrifying Sebastian could be in a killing spree. Amu shivers at the memories. Grell notices this and rubs her back soothingly.

"Spears, what if I give her my blood? Would that work?"

Spears was so startled that it showed on his face, "Are you daft?! Grimreaper blood is poison, you idiot!"

"She's a cambion! It wouldn't be deadly to her!"

"You can't know that for sure!"

Amu stands between them, trying to calm Spears and assuring Grell she doesn't need his blood and does not want to kill herself on lethal blood potentially.

"Would you know what happens to a succubi if they abstain from sex?"

Spears sighed, adjusting his spectacles, "They can't."

"Can't what?"

"Abstain. Once puberty sets in, sex is what gives them energy. Food becomes tasteless. Nothing else gives them sustenance."

Amu could feel a headache coming on. "How long after puberty do they start having sex?"

"Not long after. From what the clam members have boasted - the older clan members teach the young the pleasures of flesh thoroughly and intimately. Afterwards, once confident - they seek out their kindred human to make as their lover."

Amu groans; it wasn't a headache. It was a fucking migraine.

Spears is slightly reddish in the face when he leaves later but wishes Amu good luck with her situation. Grell meanwhile pouted irritably, complaining Spears didn't help much. Amu silently agreed, but it was partially fruitless. She would need to come up with a plan.

Later that night, Amu discussed the recent developments with her guardian character. At the end of it, Kurosu was so appalled she would have kicked her bearer in the face if she could. "Are you mad? You want to try drinking human blood?!"

"I-"

"Sebastian already said that your physiology is changing! What if it changes even more when you start acting like a succubi?!"

"I HAVE NO CHOICE! I WAS IN PAIN FOR A WEEK UNTIL SEBASTIAN SHOWED UP TODAY!"

Kurosu staggered back, surprised that Amu raised her voice.

"Amu...you could just tell Ciel how you feel. You don't have to bear with this-"

"Ciel is engaged. Lizzy is such a nice, sweet person. I cannot wreck someone's life like that."

Kurosu's eyes softened, "Amu-chan..."

"I made up my mind. I need to control this hunger, or I will end up dying from this pain or hurting somebody else."

Kurosu pitied her bearer. She knew Amu was in pain but didn't realise how tormenting it must have been to push her to this. "All right, who do you want to drink from first?"

Kurosu's breath hitched as a steely look came over her bearer. "Cheslock."
