So I know that Kanato had a scene before this one, but...I'm sorry to say I couldn't really come up with anything for it that felt believable to me, so I skipped to this one. If I think of something later, I'll come back to it. Also, to my readers who have mentioned threesomes—I played with that idea, but I couldn't come up with anything I liked for it. I just can't really imagine Ayato being okay with sharing Yui's attention, and especially not in that capacity.

Sixth

The idea of Ayato and Laito both doing whatever they wanted to her at the same time was absolutely terrifying. She didn't think Ayato would agree to it, either, yet he still said, "Do what you want," to Laito.

So there Yui was, underground and being held against rusty iron bars by Ayato, wondering how she was going to get herself out of this. It had been long enough for her to figure out that they weren't going to push her to the point of killing her. Maybe if she came up with a good enough argument, they would let her off. Ayato, at least, seemed aware that Yui wasn't feeling like herself. He stopped drinking when her heart throbbed painfully, like he could taste it.

As she tried to think, Laito stepped closer.

"Okay," he said, "let's have fun with this."

"No," Yui tried to protest.

"Don't bother," Laito advised with a pleasant smile as he knelt down. "You can't get away from me. Give up."

Like Yui needed to be reminded. She knew she couldn't get away.

"Fun fact," Laito went on, lifting the skirt of her nightgown to expose her thigh. "Once a butterfly is caught in a spider's web, thrashing about only entangles it more." He hitched her thigh over his shoulder. "So hold still while I give you some loving, okay?"

He bit her. As usual, he was cruelly passionate.

He unlatched after a quick gulp and said, "I love you, Bitch-chan," before biting in again.

It wasn't the first time Laito had given her those hollow words.

They seemed to strangely agitate Ayato. He tugged the sleeve of Yui's nightgown down enough to expose her shoulder before biting into her again. He was squeezing her wrists so tight against those bars that her hands were starting to feel numb.

And then he stopped.

"Damn," he grumbled, "I'm bored with this. Forget it."

He pushed away from Yui, letting her arms fall limply to her sides, and just walked away.

Laito raised his head from Yui's thigh for a moment to watch him. Yui wasn't sure what to call the look on his face. It wasn't concern or confusion, which was what Yui might have felt if she wasn't so relieved and lightheaded. She had heard of threesomes, but she had no idea how they were supposed to work. The thought of them taking turns with her and watching when it wasn't their turn was just awkward and embarrassing and downright unpleasant.

"Disappointed?" Laito asked.

Yui fixed Laito, who was still kneeling at her feet, with a questioning look.

"You were hoping you'd get to play with both of us at the same time, weren't you?" Laito clarified.

"I was not!" Yui denied with more force than she felt capable of.

"No need to be embarrassed, Bitch-chan," Laito said, standing. He hitched one of his legs up between hers and slid his arms through the gaps in the bars so his elbows could rest at either side of her head on the horizontal supports. "We all know what a little slut you are."

Yui gave Laito a tired look. She'd grown used to those remarks. They didn't bother her anymore.

"I'm not feeling well, Laito," she told him.

Laito hummed with amusement, and then kissed her aggressively. Yui made noises of protest and tried to push him away, but as usual, nothing she did made any difference. He didn't stop until he wanted to, and then he leaned down to bite into her neck, inciting a throaty scream that echoed around them in the dark tunnel.

"Mm," Laito hummed, lifting his head again. "You know, Bitch-chan, I was having a dream earlier. When I woke up I just felt the urge to come down here." He licked her neck. "Who knew you'd be waiting for me?" He pressed closer to her. "How exactly did you get down here?"

"I…I don't know," Yui admitted, too distracted by Laito's body to think of anything else.

When he was so fully close to her, caging her in like that, she almost wanted to lean in to him. That was absolutely unacceptable.

"Laito, I'm really not feeling well," she persisted. "Please get away from me."

"Oh, don't worry," Laito replied.

He took a step back, much to Yui's surprise. He took off his hat and lightly placed it on Yui's head, but it was too big. It slipped nearly halfway down her face, covering her eyes.

"What are you—"

Yui had raised her hands to lift the hat back off her head, but cut off with a surprised shriek at the feeling of something tight around her wrist. She quickly—shockingly quickly—found her wrists above her head and bound together to one of the iron bars by a long strip of cloth.

"I'll make you feel much better," Laito promised, practically singing.

"Let me go!" Yui pleaded. "I don't like this!"

"Oh?" Laito questioned.

Yui couldn't see. Laito's hat was still on her head and blocking her eyes completely. She could only feel him slide the tip of his finger from her knee to the band of her underwear. He slipped the finger in and felt around her already slick womanhood, sliding up and down her clitoris, making her loins clench. She pressed her thighs together, but it didn't hinder his movements in the slightest.

"Your body tells me something different, Bitch-chan," he murmured, lips right next to her ear.

Yui didn't respond. She kept her jaw clamped shut. Laito knew exactly where and how to touch her to get her very hot very fast.

"Just relax," Laito commanded softly, caressing her mind with his voice. "Don't hold back. Your god isn't real. No one's going to save you. You might as well let yourself enjoy it."

A tear escaped Yui's eye and ran down her cheek. She didn't know what it was about Laito, but he somehow managed to get under her skin way more than any of his brothers.

Laito chuckled and licked it before it reached her chin. "Almost as good as your blood."

Yui swallowed dryly. "Laito," she panted meekly, "stop it…"

"Still so stubborn," Laito mused. "I love that about you, Bitch-chan."

He hitched one of her legs up and hooked his elbow under her knee and slid into her easily. She gasped at the surprising amount of friction. Was it because they were both standing?

"Hey, Bitch-chan," Laito said, "brace yourself."

Yui stiffened. He'd never given her an order like that before. "What?" she questioned.

Laito lifted her other leg as well. It put a lot of strain on Yui's arms, but not enough to distract her when Laito started thrusting. He moved quickly and roughly enough to make his hat fall off her head and she could finally see again. He was looking at her in an almost drunken way, flushed and grinning.

The angle he had her at made it easier for him to pump straight in and out and repeatedly hit a spot that made her scream internally. She came fast, strained whimpers escaping her lips as she gasped and panted.

"You really don't know how to hold back, do you?" Laito noted, slowing his pace just enough for him to speak clearly. "It's much better, you know, when you take your time."

"Laito," Yui panted, "please…I can't…take anymore…"

Laito chuckled. "Sure you can." He pulled out of her, dropped her legs, and quickly turned her around so he could slam back into her hard from behind, making her cry out. "All you have to do is enjoy the ride."

Yui wasn't sure how she was supposed to "enjoy" such a rough pounding. He dug his nails into her hips and kept them angled in a way that made her feel his deep thrusts all the way up her spine. It hurt and no amount of crying helped. She almost felt like she was going to be split in half.

She was amazed when she realized her body was adjusting enough for it to feel as good as it felt painful. Another orgasm started building, but it was slower than usual. The greater the pressure got, the more she felt like her hips were going break.

Laito came before her. She only knew because when he did, he dug himself as deeply into her as he could and she felt him twitching. Before she could even start to catch her breath, he bit into her with a pleasured moan, instantly maxing the pressure out. She came hard. Spasms ricocheted throughout her tense, sore body.

If he tried dragging this out as long as he usually did, Yui was sure she would pass out cold.

Laito lifted his head and took a step back. As soon as he separated himself from her, Yui's legs gave out on her. She hung limply by her screaming wrists, unable to do anything else.

Laito sighed adoringly. "I could just spend all day with you like this," he said.

Yui didn't even have the energy to turn her head and give him a look of horror. And her heart was starting to throb in that painful way again.

Laito fixed his pants and put his hat back on, and then untied Yui's wrists. She would have fallen right to the stone floor, but Laito caught her and picked her up, making her groan. She was definitely going to be sore for a while.

"But maybe some other time," Laito recanted, still looking amused. "Bitch-chan looks like she's going to faint, and that's no fun for anyone but Kanato."

Yui let her head lull against Laito's shoulder and pressed her hand against her sternum.

"My chest," she whispered.

"Hmm?"

"Why have I been getting these pains in my chest?"

Laito stopped walking for a moment and lifted Yui a bit higher so he could press his ear against her sternum. Yui could just barely make out the change in his expression. It was subtle, but he looked displeased, like the sound of her heartbeat was painful for him to hear.

He started walking again, holding her tighter than before, but if he had an explanation for her pains, he didn't offer it to her. He remained silent. The only sounds around them were rushing water and Laito's footsteps, and Yui didn't have the energy to press for answers.

She was unconscious before they even made it out of the tunnel.
