Nishiki/Kamui vanilla-ish

"I must say, I was rather surprised to hear that my new bride was a manakete." Nishiki said lightly. "Even more so when I actually saw you. Such lovely white hair."

"Please spare me your flattery." Kamui coldly replied. "I agreed to marry you in order to bury the conflict between Nohr and Hoshido once and for all. Nothing less, nothing more."

Nishiki laughed for a moment.

"And you're so honest! I knew that you were raised in Nohr, but you speak so bluntly that I have to laugh."

He stopped and stared at her for a moment.

"I'm not going to force you into anything right now, but we WILL be expected to produce an heir at some point."

Kamui's expression didn't change.

"Now then, shall we turn in?"

Kamui nodded and slowly climbed into the futon, with Nishiki not far behind her.

"Good night, my bride."

For a moment, Kamui just lay there, weighing her options. Finally, she pulled herself up and climbed on top of Nishiki.

"What is it?" He seemed surprised.
"Let's get it over with." She said in a low voice. "I may not get pregnant, though."

Nishiki stared at her for a moment before smiling that infuriating smile. He reached out to stroke her cheek before guiding her face down to give her a kiss.

"You need to understand that in my tribe, we mate for life." He said quietly. "If we do this, I won't be able to let you go."
"I was under the impression that marriage was for life." Kamui replied coolly. "Even if there's no love there."

They slowly began to pull each others' clothes off. Once they were out of the way, Kamui leaned down and licked Nishiki's chest.

"Come now, surely love can be learned, too?" Nishiki protested as he brought his fingers to Kamui's pussy and began to stroke it.
"That would require learning about your partner." Kamui let out a soft moan, but didn't let her expression change.

Nishiki responded by inserting his fingers into her. Kamui let out a gasp and glared at him.

"We can learn about each other this way, can we not?" Nishiki smirked at her. "For example, would you like it if I went... deeper?"

He pushed his fingers in further. Kamui gasped again and pushed her face closer to his.

"Your breath is rather hot." Nishiki kissed her again. "I think this is something to keep in mind."

Kamui scowled before turning her attention to Nishiki's neck. She began to breathe heavily on it, but didn't touch it. When Nishiki twitched, she smirked to herself before laying open-mouthed kisses all over it.

"And this seems to be something for you to keep in mind." Nishiki was trying to sound confident and in control, but Kamui could tell his voice was quivering. Not only that, but his cock was beginning to poke her in the thigh.

Nishiki let out a small whine when she pulled back, but it turned into a moan when she grabbed his cock.

"You aren't interested in a little more foreplay?"
"I did say I wanted to get it over with."
"You're no fun."

Nishiki pouted, but gave no further protest as she pushed him in, only gasping in pleasure.

"That's a nice reaction." Kamui smirked at him. "How's it feel?"
"You're squeezing around me." He panted. "I want to... go deeper."

He grabbed her shoulders and pulled her down into an embrace, pushing himself in further. Kamui let out a loud moan and pressed her lips against his.

"That's the first time you've kissed me, my dear bride." Nishiki smiled, and somehow, it didn't even seem sarcastic.

Kamui started to buck her hips up and down, sliding Nishiki's cock in and out in a rhythm of desire. At some point, they lost track of how many times they kissed.

It wasn't clear which of them came first, but by the time they were through, they were lying side by side, both satisfied.

"Well?" Nishiki panted as he tilted his head toward her. "How was it?"
"It wasn't bad." Kamui admitted. "If we have more nights like that, then perhaps being your wife won't be as bad as I thought."
"Just like last night?" Nishiki stared at her with a raised eyebrow.
"I wouldn't mind if we... spiced things up occasionally."
"I do hope your definition of "spicing things up" doesn't involve my beast form."
"If you ever even suggest that again, I am leaving this country forever and taking the children with me."

He wasn't what she imagined, but she had to admit that the arrangement wasn't as bad as she'd initially thought.
