They all had different ways of biting her. Separate habits, almost.

Ayato was playful in a childish sort of way. He took big bites, like a kid tasting ice cream on a summer's day. He didn't stop for anything, and wouldn't stop, until he had his fill. No matter how many times she tried to push him away, he'd just hold her down tighter, telling her to stop fighting. He had no shame in moaning, fully enjoying his meal every time. And, like a child, he liked to vainly claim his territory, leaving her skin littered with love bites. "You belong to Yours Truly." He'd affirm. When he was done he'd fall on his back, rubbing his stomach and sighing, telling her how delicious she was. If he wasn't sucking the life out of her, she might have laughed.

Laito hurt. And he did it on purpose. He said it was so that she knew it was him. He would pierce her skin harshly, the sharp pain shooting up from the bite and into her head, making her wince. If she didn't gasp, he'd bite harder, until she reacted in a way that was to his liking. He was also one of the only brothers to bite her thighs. It was a shameful rush; one she'd never admit. But from his devilish smirk, she knew that he knew. When he bit her thighs, she would notice him blush, the pervert that he was, feigning embarrassment, only to make her more embarrassed. He even had the gall to lick her skin beforehand. "You like it, don't you Little Bitch?"

Kanato was forcefully sweet. He would kiss her beforehand every time, calling her a pain. But he seemed to understand the idea of a 'give and take' relationship. Although Yui didn't exactly care for his kisses. They were forced, and held nothing behind them. To him, it was just an annoying road block between him and his next meal. He liked to suck hard, which was different from biting hard, if that made sense at all. It allowed more blood to collect into his mouth, and it sort of numbed the sensation of the bite. "So sweet, ne, Teddy?" He never seemed to acknowledge the fact that she was even there. She was just food that happened to move.

Reiji also made her blood rush. In a different sort of way from Laito. He wasn't as rough, but he could be, so she let him drink her whenever he wanted, and she did so without protest. Reiji was scary when he was mad. He was one of the only brothers who genuinely frightened her. It didn't quite hurt, when he bit her, but it did hold a sharp sting, almost like a needle. What she found curious was that he almost never drank enough to where she could tell he was fully satisfied. He took what he needed, and nothing more. "Get out. I have work to do." He tossed her aside easily. Like Kanata, to Reiji, Yui was just a convenient source of nourishment.

Shu was bold and silent. Rough and uncaring, his bites made her long for more. She assumed it was because he was probably the most handsome brother, but at the same time one of the most impassive. He was always in his own world, lost in his music. If she happened to walk by he'd grab her by the arm, not saying a word, and sink his teeth into anywhere he found convenient. But it was never without running his fingers over the skin he sought to break. It made her shiver, the way his cold hands touched her skin, almost as though he were numbing it before striking it with pain. "So noisy." He'd leave without saying much else, readjusting his headphones.

Subaru…she couldn't think of him without smiling. He was the brother who bit her the least, waiting until he was absolutely famished. He was the only brother who held her while doing so. They all pinned her down of course, but Subaru would wrap one arm around her waist and with the other he'd push her hair out of the way, so that he could bite her neck. It was strangely romantic, and it made her heart thump in erratic patterns. His bite was essentially painless. She was grateful for it. Though she didn't think he'd ever admit it, he took her feelings into account. Like Reiji, he didn't take more than he needed, but sometimes, she felt his lips linger on her skin, and she found herself hoping he'd kiss her. He never did though, and he always pulled away quickly. "How annoying." He'd spit out. It tugged at her heart, when he said that.

In that sense, she preferred Subaru. He was kind, in his own way. And when he said those words, she couldn't help but feel that they weren't exactly directed towards her. It felt almost as though he were talking to himself; fighting something. Perhaps that's why he left his lips on her neck for so long, not doing anything.

She collapsed into bed, particularly exhausted after returning from school, and wrapped the covers tightly around herself. It was a futile exercise; she knew something as simple as bedsheets wouldn't stop the vampires she had gotten used to living with. But she did it anyway, falling into a drowsy sleep, wondering which one would wake her up first.

A/N: Which one is your favorite? I can't decide! Just a short sort of drabble, I do plan to make lemons for some of the brothers later on. Let me know what you think :D
