How about Hux and Kylo, reluctant bath? Like they're on a planet trying to get them to join the FO. Hux walks in to Kylo's room because he wants to have a meeting about their strategy, only to find Kylo lounging in an enormous bathtub. After some argument, Kylo demands Hux give him a hand to get out of the tub. Instead Hux finds himself being pulled in to the bath fully clothed.
Things seemed off to an excellent start, judging by the accommodations. This particular planet had never been much trouble for the First Order, and it seemed to Hux as though they would be happy to come willingly, in exchange for protection from rebel activities. The hotel rooms (no one knew of their relationship but them, they’d made sure of that, so of course they were given separate rooms) Ren and Hux had been given were spacious and elegant, stocked with wines and sweets, and with sweeping views of the glittering city below–so large that it seemed to stretch the horizon, the nine moons hanging neatly-spaced in the sky above.
Hux had long ago gotten used to extended voyages through space and the lag hardly affected him anymore–he was ready to meet with the officials nearly from the moment the droid had put his bags away, but he supposed he’d need to give Ren a little while to make himself properly intimidating. He allowed a good half hour to go by before sending a message on his data pad encouraging him to meet him so they could gather the officials to discuss strategy, and then another ten minutes before he went over and let himself into the room Ren had been given. When it came to the designing of superweapons and moving through the ranks of the military, Hux had a pretty decent degree of patience, but when it came to the smaller things, he had no capacity to wait.
At first he didn’t think Ren was even in his room–the bed was empty, the desk chair empty, the window seat that allowed him to look out at the sky empty. But then he heard the sloshing of water, and with a flash of irritation, Hux realized Ren was in the bathtub. Had he not told Ren they were going to call a meeting shortly after awhile? It was like Ren had a mute button on that idiot helmet, tuning Hux out entirely.
The bathtub was huge–it would have to be, for Ren to lie comfortably–and more ornate than anything Hux had ever seen. It stood on four gold feet and was filled with scented water, as well as Ren’s bulk. He looked to be in no hurry as he sank lower, letting his hair float down around his cheeks.
“Ren, did you not hear me when I said we’d be beginning negotiations immediately?”
Ren lowered himself even further, his earlobes just barely grazing the surface of the water. “General,” he nearly purred, which just made Hux madder. “You don’t want me to show up to a meeting covered in the dirt of travel, do you?”
“You wear your robes and your mask, no one has to know you’re unwashed under there.”
“I will know,” Ren argued. “It will affect the negotiations if I feel irritable and filthy, won’t it? And that is not–” His eyes flashed with mischief. “A meeting you wish to attend, General.”
Hux sighed. “Well, you look perfectly clean to me now. Get going.”
Ren tossed his head, making his hair undulate in slow motion. “I’ve sunk too far. You’ll have to pull me out.”
“Are you fucking kidding me?”
Ren lifted his arm. “Walk away and I’m not getting out, General.”
Hux felt himself go hot with anger. Just another one of Ren’s power games that he’d have to play if he wanted things to go smoothly on this trip. Very well, then, whatever–He stalked over, rolled back one sleeve, and took Ren’s hand in his. Pulled with all his strength, but Ren was pulling too, making no attempt to lift himself–
“Ren!” he barely had time to say before losing his balance entirely and landing, headfirst, soaking his fine dress uniform, having to practically swim to right himself. He spat out a mouthful of soapy water, wincing. “You absolute brute!” he screamed, trying in vain to put his hair back in order. “Look at me!”
“If you’re in, you might as well enjoy it,” Ren suggested, contorting his face into an expression he imagined was innocent.
“No, I was waiting for you to be finished with your little idle pastime first–”
“So no one is waiting for us,” Ren interjected.
Dripping, Hux began peeling off his clothes in defeat. “You’re paying for those to be laundered, you animal.”
“And you are going to send a message to the officials thanking them for their generosity and telling them you expect to see them for a meeting first thing tomorrow morning,” Ren answered, helping Hux speed the process along. The soaking wet clothes landed on the marble floor with a plop.
“Fine,” Hux growled. “I suppose that might be more convenient for them, anyway.”
Loathe as he was to admit it, the water was so pleasantly warm and the soaps were soothing as long as they weren’t in the mouth. Perhaps Ren had a point. He’d need to be clean and presentable for tomorrow’s meeting. And he could even lie to himself and pretend that fucking in the bath might sate them both awhile, for the duration of this trip. He settled back, fully undressed now, wondering how Ren might try and improve his mood.
