I wanna swim between your thighs

Summary:

Feng Xin was frozen in place. Mu Qing’s eyes were closed, his arm still around Feng Xin’s middle. Feng Xin’s chest was going to explode. “Mu—”

Mu Qing’s eyes flew open. “I said shut the fuck up, Feng Xin. Can’t you give a man a moment to himself before he breaks his eight hundred years old vows of celibacy?”

Feng Xin shut the fuck up.

Notes:

this is the prequel 'first-time fic' for something i wrote a few months ago, but it can be read alone. if you're confused about the demi mq tag here, that fic will make it more clear, but this one is from fx's pov so it won't be "visible" here (but i suspect any mu qing i ever write will always be demi, so there's that)

beta'd by my lovely friend whose comments on the margin of the google doc make everything better; all mistakes are mine and english keeps not being my first language

title from måneskin (for consistency with its sequel, and it's also nice that it fit)

(See the end of the work for more notes.)

Work Text:

Feng Xin paced back and forth in his training grounds. He’d give Mu Qing another incense stick’s time to arrive, and then he would set up arrays upon arrays to deny him access to his palace forever. 

Fuck him. Fuck him. 

This tentative friendship between them was too new and fragile to treat it as carelessly as Mu Qing did. Feng Xin knew that fighting was the easiest excuse they had to meet, just the two of them without Dianxia or without a mission to take care of.

Feng Xin cared too much about… this, whatever it was, and he wanted to see where it would lead them. If it was a solid friendship, then Feng Xin would welcome it with open arms. And if it was something else, then… But he didn’t let himself hope, not even the times when his traitorous heart told him that Mu Qing might feel the same. 

Mu Qing was still too much of a mystery and Feng Xin was aware that any misstep from his part had the potential to lead to a complete catastrophe. But apparently Mu Qing didn’t feel the same about that, because he was over a shichen late and he was silent in the communication array despite the many attempts Feng Xin had made to contact him.

One incense stick’s time had certainly passed, but maybe Feng Xin would give him one more. Or two. He didn’t want Dianxia to think he had given up on on his friendship with Mu Qing too soon, but damn it he was fucking pissed. Maybe he should just go look for him, since it was clear he wasn’t—

Mu Qing stormed into the training courtyard with murder in his eyes, and fuck him for looking so hot when he was in a mood. Which meant he was hot always and Feng Xin couldn’t catch a fucking break.

It only took him a beat to notice the blood on Mu Qing, and then he was in his space, touching him all over to look for wounds.

“Fuck! Where the fuck have you been?? Is this yours?? Mu Qing, are you hurt?”

Mu Qing pushed him away. “Get off me. I’m fine. Just fucking pissed.”

“What happened?”

Mu Qing rolled his eyes. “What else? A ghost. I don’t want to talk about it.”

“Why didn’t you tell me? I would’ve helped.”

“There was an array, a trap. It didn’t steal my spiritual power, but I couldn’t contact the communication array at all. Now stop talking and let’s fight.”

“Fight?? Are you in any condition to fight? I’m not fighting you when you’re already—”

A fist to his stomach shut him up.

“You’re a fucking asshole, do you know that?”

“You make sure to remind me every day.”

Two hours later they were bruised and down to their trousers, the rest of their clothes discarded along the fight. They were panting and sweaty and Feng Xin was sitting on top of Mu Qing with his hands around his throat, not squeezing, just feeling his blood pumping. He was about to ask him to yield and he didn’t know why it was taking him so long. There was something in Mu Qing’s eyes, something he couldn’t name, and with a small shift in his position he felt—

Mu Qing’s eyes widened, and then Feng Xin was being kicked and pushed off of him. He fell on the hard floor and watched Mu Qing storm off without a word. 

Feng Xin couldn’t let it happen. He hurried off the ground. 

“Mu Qing, wait! Mu Qing!”

He reached him as he was about to leave the courtyard and none too gently grabbed his arm and shoved him to the nearest wall. He had no plan. How could he have planned for something like this? He took in Mu Qing’s red face and angry expression and simply pressed his body to his.

Mu Qing’s sharp intake of breath told him he had felt exactly what Feng Xin wanted him to feel.

“You fucking shameless…” Mu Qing said, but it sounded weak. He was as tall and as strong as Feng Xin was. If he had truly wanted to get out of Feng Xin’s hold, he could have. 

“Mu Qing, hey… It’s okay. You don’t have to feel embarrassed.”

“Fuck you.”

Feng Xin couldn’t help raising an eyebrow. Any reply to that would have been too easy and wouldn’t have improved the situation.

Mu Qing punched his chest before letting out a loud, frustrated grunt and covering his face with his hands. “You’re the fucking worst. Stop looking at me.” He still made no move to leave.

“Hey,” Feng Xin tried. “This doesn’t have to be anything, you know that, right? Your… I respect your cultivation. I hope you know that.”

“Shut up.”

Feng Xin sighed. “Okay.” He started to let go. 

“I said,” Mu Qing’s strong arm pulled him back to himself. “ Shut up, not leave. You’re so fucking…”

Feng Xin was frozen in place. Mu Qing’s eyes were closed, his arm still around Feng Xin’s middle. Feng Xin’s chest was going to explode. “Mu—”

Mu Qing’s eyes flew open. “I said shut the fuck up, Feng Xin. Can’t you give a man a moment to himself before he breaks his eight hundred years old vows of celibacy?”

Feng Xin shut the fuck up.

Whatever was going through Mu Qing’s head, at some point he rested his forehead against Feng Xin’s shoulder, breathing heavily. Feng Xin lay his hand on the back of his head, half expecting Mu Qing to start yelling at him again. Instead, he felt Mu Qing relax against him, so he added an arm around his shoulder, too. He was briefly reminded of finding stray cats and testing their boundaries, knowing that a bite or a scratch could come at any time. 

But instead of biting or scratching him, Mu Qing turned his head so that his mouth was on Feng Xin’s neck. It wasn’t a kiss, not yet, but Feng Xin felt the contact in his whole body. 

Then Mu Qing’s arm that was still holding him went lower, his hand squeezing Feng Xin’s ass and pulling him closer. Feng Xin tightened his hold on Mu Qing’s hair and pulled so he could look him in the eye.

“Fuck, you’re so…” Horny. The realization hit Feng Xin with the might of a heavenly calamity.  Mu Qing was horny and willing to change the course of his cultivation forever. Willing to do this with Feng Xin of all people.

Mu Qing didn't give him the chance to voice any of this. He attacked his mouth in such a Mu Qing way that it would've made Feng Xin laugh if he hadn't been occupied trying to keep pace with him, guiding him into something more like kissing than fighting. He felt the moment Mu Qing settled into the rhythm, and then Feng Xin melted into it. 

Mu Qing had always been a quick learner.

Now that this was truly happening, Feng Xin realized how hard he truly was. He could already feel his precum dampening his trousers and he couldn't help but press his hips even further into Mu Qing's to seek friction.

Mu Qing moaned into his mouth, pulling away from the kiss to look down between them. Feng Xin watched him trace the outline of his cock with soft fingers, then palming him fully without warning. 

“A- ah, fuck,” he moaned, and quickly pulled down his trousers. He felt Mu Qing tense, saw his eyes widen. Then, a split instant later, Mu Qing sank to his knees.

It was only because of the shock of seeing something he never thought he'd see that he didn't come on the spot when Mu Qing licked from base to tip, keeping his eyes closed and only opening when he reached the head and took it fully into his mouth. Then Feng Xin almost came, and he quickly pulled away because no way was he going to embarrass himself like that.

“Hold on hold on hold on, Mu Qing, fuck! You're so fucking eager, calm down for a second!”

Mu Qing didn't even pretend not to be staring at his cock. “Like you haven't noticed I've been obsessed with your cock for centuries.”

“Wh— that dumb Ju Yang bullshit? Seriously?” Feng Xin laughed, almost hysterical. He normally only felt annoyed at any reminder of Ju Yang, especially if it came from Mu Qing, but the admission, paired with what they were already doing, only made him feel strangely flattered. 

He hooked a finger below Mu Qing’s chin. “Come here if you’re so obsessed with it.”

Mu Qing came willingly without protesting and Feng Xin kissed him slowly and thoroughly. He infused a small amount of spiritual energy into the kiss. 

Mu Qing pulled back briefly. “Why?”

“You’ll need it.” Feng Xin said against his lips. They both begrudgingly knew enough details about Dianxia and Crimson Rain’s relationship to know how this worked. “Have you already lost some?”

Mu Qing shook his head. “I think I need to…finish. First.”

“Don’t bite my dick off, and this is not me doubting you, but I need to ask if you’re sure about this.” He would have asked any partner, but he wanted to be extra careful about it with Mu Qing. “I want you to enjoy it,” he added, realizing that it was true.

“Yes.” Mu Qing punctuated the answer with a kiss. “I want it. Now haven’t I waited long enough?”

Feng Xin smirked. “Turn around,” he said. 

Mu Qing turned around and Feng Xin moved his hair over one shoulder so he could kiss his neck. He cared about his life enough not to leave marks on him unless Mu Qing asked. He’d have to ask another time, but he had other plans now.

Slowly sinking to his knees, he kissed the planes of Mu Qing’s back as he went, relishing the muscle he had so often felt during their fights. He liked this so much better.

When he was on his knees he removed Mu Qing’s troursers. Here he allowed himself a small bite of Mu Qing’s tight ass, and if the noise Mu Qing tried and failed to suppress was any indication, he didn’t mind it in the least.

Then he spread his cheeks and Mu Qing moaned, moaned before Feng Xin even did anything more than that.

“You good?” He teased.

“F- Fuck you.”

“With pleasure.”

He started circling Mu Qing’s hole with the tip of his finger, not pressing down but just gently caressing him and relishing the way Mu Qing moved and squirmed, trying to fuck himself on Feng Xin’s finger. Feng Xin didn’t want to, not without oil, not when Mu Qing was too horny and desperate to know what was good for him. So he replaced his finger with his tongue, spreading Mu Qing's cheeks further to probe at his hole. 

Mu Qing, Feng Xin realized, wasn’t quiet. He wasn’t quiet when he teased Feng Xin and fought with him or when he cursed the way his believers had built one of his statues, but the times Feng Xin had allowed himself to imagine what he would be like while being touched, while being pleasured, he hadn't let his imagination go as far as imagining what sounds he would make. Even if he had tried to, he would've thought Mu Qing quiet, or trying his best to resist the sounds that instead came out of his mouth now.

“You're doing so well, taking my tongue so beautifully.” Feng Xin said. He looked up and saw Mu Qing sweaty and panting. His eyes were closed and he was bracing himself against the wall. “I bet you'd be so tight on my fingers. Would you ever relax enough to take my cock, Mu Qing?”

“Y- yes,” Mu Qing said, and Feng Xin was torn between the laugh that threatened to escape from his chest and the twitch of his cock at the seriousness with which Mu Qing had taken his dirty talk.

He allowed himself a couple of strokes of his dick, planting a loud kiss on Mu Qing's hole before rising to his feet again.

“Really?" He asked.

Mu Qing turned around just enough to kiss him sideways and Feng Xin was once again taken aback by the directness of this unhinged Mu Qing, who didn't even mind kissing him despite where his mouth had just been. 

“You want my cock, Mu Qing?” He pressed. He slid it in the crease of Mu Qing's ass, eliciting a loud moan again.

“Fucking do something,” Mu Qing said.

Feng Xin was too far gone to keep teasing him. He pumped his cock to spread precum on it. Then he reached around to take Mu Qing's dick in his hand, finding it already wet and leaking.

“Open your thighs for me,” he whispered against Mu Qing's ear. 

“A- ah, Feng Xin, what are… Oh,” Mu Qing whimpered.

Feng Xin's cock slid between Mu Qing's thighs as if it belonged there. He would have preferred to have some oil, but this was good too. Neither of them was going to last long enough for their skins to chafe, not with the way Mu Qing was panting and moaning and the way his sounds went straight to Feng Xin's cock.

He kept kissing Mu Qing's neck as he pumped his cock and fucked his thighs, whispering loving nonsense against his skin. Soon he found himself holding Mu Qing tighter and increasing his pace. 

“Fuck, Mu Qing, I'm close,” he moaned.

“Feng Xin, ah— Feng Xin, I'm going to—”

He felt Mu Qing spill in his hand, cum spreading to the rest of Mu Qing's dick as Feng Xin kept jerking him through his orgasm. 

Feng Xin followed him over the edge while calling his name.

He kept holding Mu Qing as if he might disappear if he let go, but Mu Qing let himself be held and kissed like he was equally scared to be left alone after what they just did. 

As if Feng Xin ever would.

Mu Qing turned into his arms so they were chest to chest again, kissing languidly against the wall where they had just fucked. 

Feng Xin found Mu Qing's pulse and felt for his spiritual energy, finding it indeed diminished.

“How do you feel?” He asked softly.

Mu Qing sighed. “Weaker. It's fine.”

Feng Xin kisses his cheek. “It's not fine. I know you don't like feeling weak. Let me help you?”

Mu Qing hesitated. Feng Xin wondered if he was considering whether he'd hate being helped by Feng Xin more than he hated not being at the top of his strength, but then he nodded and closed his eyes, leaning in towards Feng Xin's mouth.

Feng Xin drew back a bit, a smile on his lips. Mu Qing opened one eye, frowning and clearly annoyed. “What?”

“Nothing,” he laughed, and he pressed his mouth to him before he could say any of the things he was thinking. I never imagined you'd be so open once you let go. I like how eager you are. I like you.

He gave Mu Qing enough spiritual energy that they were equal once again. He kept kissing him long after, their kisses getting more heated and their bodies seeking friction against each other until they were both again fully hard and panting into each other’s mouths.

Feng Xin gasped when he felt Mu Qing’s hand around his cock. He wrapped his hand around his to stop him. “Do you really want to keep fucking against this wall?”

Mu Qing looked around as if considering the location, then gave a pointed look at their arousals. “Seems perfectly fine to me,” he deadpanned. “For a room in Nan Yang Palace,” he added.

Feng Xin wanted to roll his eyes. “I also have a perfectly fine, comfortable bed.”

Mu Qing’s expression was carefully blank for a moment. “I’ll be the judge of that,” he said.

Later, entirely fucked out and wrapped around each other on Feng Xin’s bed, Feng Xin entirely deserved the elbow he took to his ribs after asking Mu Qing whether or not his bed was comfortable.
