Second

Yui had to wonder if she would ever actually get used to the way vampires could just appear wherever they wanted whenever they wanted.

And what point even was there in having a lock on a door if it didn't make a difference? It certainly didn't stop Shu from materializing in the bathtub she had just filled for herself.

"Shu?!" she questioned apprehensively as soon as she realized he was there.

She had only just escaped from Ayato. Was she going to have to escape from this one now?

Then again, Shu didn't seem to have any interest in her. He didn't seem to have any interest in anything. Maybe he wasn't there for her blood…or anything else…

"Keep it down," he muttered. "You're too loud."

Yui approached him slowly, unsure of what to make of this. Why did he appear in the bathroom that Reiji told her would be exclusively for her use? And why did he get in the bath with his clothes still on? He hadn't even taken off his sweater.

"I'm just taking a bath," Shu said, perhaps in response to her questioning look.

"But you're still dressed," Yui said.

"So undress me," Shu replied tonelessly. "You wanted to see me naked anyway, right?"

"O-of course not!" Yui snapped. "Don't even suggest something like that! I came in here to take a bath!"

Shu actually looked at her and smirked a little. "Want to join me?"

"Why would I want to do that?!" Yui demanded.

"You're blushing," Shu told her.

Of course she was blushing. What girl wouldn't blush at a suggestion like that?

Shu sighed and sank a little further down the water. "I feel so tired," he murmured.

Yui's eyebrows pulled together and up a bit. "You're all brothers… Why are you all so different?"

"We have different mothers," Shu said.

"What?"

"Reiji and I had the same mother," Shu elaborated. "Ayato, Kanato, and Laito are from another mother."

"I didn't know," Yui mumbled. "Then…what about Subaru?"

"He has a different mother," Shu told her, and then sank all the way down into the tub.

"Shu?!" Yui panicked. Was there something wrong with him?

She grabbed his hand and pulled his head back up to prevent him from drowning.

Shu just looked at her hands. They were much smaller than his.

"Shu?" Yui questioned.

Shu curled his fingers around one of her hands, apparently lost in thought, and started squeezing. He squeezed tighter and tighter as the seconds ticked by.

"Shu?" Yui whimpered, trying to pull her hand out of his. "Shu? Shu! You're hurting me!"

Shu looked up at her, then, almost like he had forgotten she was there. His grip loosened slightly, but he didn't let her go.

Rather, after a second of deliberation, he tugged her right down into the tub and said, "Let me drink your blood."

Yui looked up at him, wide eyed.

"What?" he questioned. "Are you scared?"

Before Yui could find her voice, Shu reached out and clamped his hand around the nape of her neck and pulled her closer. He pulled her hair back so he could get a good look at her neck.

"So pale," he commented. "I bet your blood spurts right out of it like a geyser." He huffed humorously. "Did Ayato do that?"

Obviously, he was referring to the two hickies below her collarbone. Ayato had come to her for blood and possibly more, but had allowed her to escape to the bathroom after marking her up a bit. He was waiting for her to finish bathing before doing what he wanted to her, only because he didn't want to deal with the possibility of her fainting in the tub.

"He's such a possessive freak," Shu muttered.

Yui gulped dryly. It was with a strained voice that she said, "I thought…I thought you were different…why…?"

The look Shu gave her was almost stern.

"Make no mistake," he said, "I am a vampire."

A shiver went up Yui's spine. She could see his fangs when he talked.

He smirked a little again and said, "I'll show you a whole new world," as he leaned down to her neck.

He bit it.

It felt different from Ayato. Ayato's bites were quick and rough and playful. Shu's bite was slow and somehow less sharp.

He gulped down a mouthful and sighed in a pleased way. He lifted his head just enough to speak.

"Your blood is so hot," he murmured in her ear, making her tremble. "I could get burned."

Yui decided that vampires really did have hypnotic voices. Shu's vibrated all the way down to her core and sent tremors throughout her entire body. It almost made her forget that this wasn't okay.

"You're getting excited," Shu noted. "What a dirty girl, getting hot with fangs at your throat."

"No," Yui tried to deny, but her voice was trembling.

Shu huffed with amusement. "I understand now why you came to live with us. You have some fine, high-quality blood."

"Please," Yui said shakily, "let me go…"

Shu bit her again in response and drank longer this time. As he drank, he shifted one of his legs between hers and got a grip on her thigh with is free hand, effectively preventing her from trying to stand. He shifted, leaned back while making her lean with him, drinking continuously.

Yui was practically lying on top of him.

After a couple seconds, Shu lifted his head and let if fall back, exhaling, neck bent over the tub's rim. His grips on Yui's hair and thigh loosened slightly.

Yui stayed still, initially, aside from some involuntary tremors. She waited, but Shu didn't do or say anything until she tentatively tried to get off of him.

He retightened his grip at first. Yui gasped sharply at his tugging on her hair and whimpered at the feeling of his nails digging into her flesh. She figured he would drink more blood, especially after he lifted his head back up and looked at her neck contemplatively, like he was trying to decide which side he should bite.

Instead, he let his hand fall from her hair and said, "Take off your sweater."

It was a lethargic command. He almost sounded like he didn't care whether or not she did it.

"Did you hear me?" he questioned when, even after a few seconds, Yui did nothing but stare at him with wide, disbelieving eyes. "Take off your sweater."

"No," Yui refused.

She tried to get up, but Shu just clamped his other hand down on her other thigh and slid her a little further back on his leg, inciting her to hum throatily. She was horrified with herself as soon as she realized what kind of noise had passed her lips.

Shu smirked. "Already warmed up, huh? Good. Take off your sweater." He let go of her thighs, which throbbed where his fingers had been. "And your shorts."

Yui couldn't decide what to do. The idea of following his orders and letting him do the same things to her that Ayato had done was terrifying, but so was the idea of not doing what he told her to. She was scared either way.

"What's wrong?" Shu asked apathetically. "It's not like you're a virgin."

Yui folded her arms to her chest and looked down.

No, she wasn't a virgin anymore. Did they all know? Had Ayato told them about it?

She glanced up at Shu. There was nothing judgmental or mocking in his expression, but she did see signs of irritation and impatience. He wasn't as intimidating as his brothers, but something told Yui that making him angry would be a bad mistake to make.

It was with trembling hands that she gripped the bottom of her sweater and pulled it over her head. She dropped it over the side of the tub. To get her shorts off, Shu did let her slide off his leg and retreat to the other side of the tub. After she discarded them onto the bathroom floor, she stayed where she was, curled in a ball. She could feel Shu's eyes boring into her, burning every inch of her exposed skin.

"Now the rest of it," he said.

Yui hated how his voice and words made her clench longingly. She did as she was told without looking at him and kept herself as curled up as she could. If she looked at him, into the eyes she could feel on her skin, she wasn't sure what she might do.

"Come here," Shu instructed.

Yui did it, albeit slowly. When she was basically in the same position she had been before, Shu huffed in that amused way.

"You must be really eager for it," he said. "Look at you, straddling me all on your own."

Yui's face flushed. "I'm not—"

Shu interrupted her by grabbing her hair and bringing her neck right to his mouth. He sank his fangs into the first set of holes he made earlier. Yui wasn't sure if it hurt less or more. A part of her mind was distracted by the fact that her knees were on either side of his hips and they were there of their own accord. He had said, "Come here," but he never told her to straddle him.

After a long, slow sip, he pulled his fangs out and licked the wounds. Yui shivered.

Shu let Yui straighten back up a bit and said, "Take my belt off."

Yui looked at him with disbelief and horror.

"Now," Shu said.

Yui hesitated. What would he to do her if she refused?

Trembling more than ever, Yui clumsily unbuckled his belt and tugged it out of the loops. She dropped it next to her sweater.

"Unbutton my pants."

Yui had almost been expecting that. She wasn't sure if Shu was just being lazy or if he was getting off on watching her do things she wasn't comfortable with. Whatever his motivation, she still didn't want to find out what he would do if she refused, so she unbuttoned his pants and unzipped them. She tried not to be aware of how obviously hard he was—tried, and failed. She was very aware of it and her knees pressed a little into either side of Shu's hips of their own accord.

Shu hummed mockingly. "You really are a dirty girl. All I told you to do was unbutton them."

Yui lifted her hands up, almost as if in surrender. She decided she didn't care what he did to her after all. It couldn't be as bad as this humiliating charade.

Perhaps Shu could see he had pushed her as far as she would go. He slid one hand under her and brushed his fingers along her labia.

"Were you touching yourself before you came in here?" Shu asked. "I wouldn't be surprised. You're already so wet."

Yui clenched her jaw. She would rather bite her tongue off than admit that she got aroused when Ayato put those hickies on her.

Shu chuckled quietly as he pulled her a bit up and forward so he could fiddle with his pants and underwear, getting them out of his way.

"Lean back," he said, still smirking. "Yes, there…now sink down…mm, like that."

It didn't hurt much, especially not compared to her experience with Ayato. Maybe it was because that had been her first time. Maybe it was because Shu wasn't forcing himself on her—rather, he was having her do most of the moving.

"Lift yourself up, then slide back down," he instructed.

Yui did as he told her, and he didn't complain about her pace. He seemed fine with her initially slow, uneven movements, and he seemed fine with it when she started to go faster. Once she got used to it, the pain went away entirely. She could sink all the way down, take all of Shu's manhood into herself, but she still didn't feel pain from it.

She could feel that pressure building again, too.

She went faster. The faster she moved, the faster it built up. She found that if she angled her hips a certain way, it created a friction that made her toes curl, and she went faster. She didn't slow down, even when the water started sloshing so much that some of it splashed over the side, or even when Shu tensed up and clutched the rim of the tub with both hands.

A low growl came from between his clenched teeth. Yui was leaning into him enough that her ear was very close to his lips, so she felt the reverberations very clearly.

The pressure maxed out and broke, sending a soft scream out from the back of her throat.

Shu quickly wrapped his arms around her to keep her in place and rapidly thrusted up into her while simultaneously pushing her down and pulling her back up. He let out a breathy growl with each thrust, sending Yui's mind into a frenzy of pleasure.

It wasn't long before he stopped, but Yui still felt like jelly. She was dizzy, breathless jelly with throbbing loins and she was fully leaning into the vampire who put her in this state. Her head had ended up tucked underneath his, so she could feel each of his quick, shallow breaths.

They stayed like that for a while. Long enough for the temperature of the water to get noticeably lower.

It was Shu who moved first. He leaned forward and folded his legs under himself so he could lean over Yui, who didn't make a sound, even when she felt the friction of him slipping out of her.

Very quietly and huskily and right into her ear, Shu murmured, "Think twice before you reach out to me again. Never forget."

And with that, he disappeared.

Now that she was alone, the full understanding of what she had just done—and enjoyed doing—sank into her.

She would never be able to look her father in the eye again.
