Switching Lanes

Summary:

"No," Sky answers the question. He's never had group sex that he consented to, which is what he assumes Rain means. "Why? Do you want one?"

"No, not me. I think P'Phayu does."

Phayu wants something from Rain. Sky finds he may have more in common with Phayu than he thought.

Work Text:

Rain has been weird all day. His and Sky's classes for the day are done with and they're still at the faculty, working on an assignment at the drafting tables. He's just looked over at Sky again and then away, like he's been doing since morning. It's obvious he wants to say something.

Sky won't ask though, won't give him the opening. Rain normally has no problem filling the silence with ceaseless babbling, needing someone to talk at not with more often than not, so if he's not speaking what's on his mind it has to be because Rain either knows what he'll say will upset Sky, or it's a sex thing. Maybe even both. Probably both.

When Rain glances at him again only to quickly look down at his work when Sky meets his eyes, Sky decides it's time to go home. It's not especially annoying or anything, but the constant feeling of being watched is distracting. He'll make more progress at home where he'll be able to concentrate.

"I'm going," he announces.

Rain immediately gets up. "Okay, I'll drive you home," he offers, smiling as he begins to pack up his things.

"No need," Sky casually tries to brush him off. Rain regularly drives him home, but right now his eagerness to leave is suspicious. Sky suspects that all it will take for Rain to finally spill is to get him in private.

"It's not a problem," Rain insists. "There's something I want to ask you about."

"Oh, really?" Sky folds his arms across his chest and narrows his eyes at him. "I hadn't been able to tell. All day."

Rain bites the inside of his lower lip and looks sheepish. "Come on, don't be mean. I want advice on something."

"That's what I'm afraid of."

Any time Rain wants advice it's always about new ways to seduce his boyfriend and Sky is tired. Everything he's learned about Rain and Phayu's sex life has been against his will.

"It's serious this time," Rain sulks.

He's full on pouting now, and Sky doesn't see anything in his eyes or expression that suggests Rain will want to talk about something silly, so he gives in.

"What did you want to talk about then?" Sky asks once they're in Rain's car.

"Er," Rain begins, then laughs nervously. He's been trying to figure out how to approach the subject delicately all day with no luck. He starts the car, because at least if he's driving Sky can't strangle him without provoking an accident that might get them both killed.

After they've made it out of the parking lot and onto the street, Rain decides he'll just have to take the plunge. "I don't know how to ask without making you mad," he prefaces before he gets the next part out all in a rush. "Have you ever had a threesome?"

Sky closes his eyes and breathes. He knew it would be a sex thing, but if it was going to be he supposes he expected worse. "That's what you were so afraid to ask me?"

"Well, yeah," Rain replies, a bit bemused at the mildness of the response. He was afraid Sky might blow up at him like the day he asked him about his ex. He doesn't want to trip over any more invisible landmines. "I didn't want to be insensitive."

Oh, right. If Rain had asked him this only a year and a half ago it might have triggered an avalanche of painful memories, but Sky's at a point where he can talk about his experiences now, at least with Rain who is privy to the details of his past abuse.

"No," Sky answers the question. He's never had group sex that he consented to, which is what he assumes Rain means. "Why? Do you want one?"

Good luck getting P'Phayu to agree to that, Sky thinks. Although, Rain wanting to have a threesome is just as surprising. He's equally jealous and possessive of Phayu as Phayu is of him.

"No, not me. I think P'Phayu does."

"Really? That's... unexpected. So is you considering it. You try to scratch anyone's eyes out for even looking twice at P'Phayu."

"Oh I know," Rain says combatively. Sky doesn't miss the tightening of his grip around the steering wheel. "But he said he just wants to watch."

"Eh?"

"I told you he likes to film us having sex sometimes, remember? But I guess he wants to see it in person too."

Sky swallows around the lump starting to form in his throat. He does remember Rain telling him that. Also remembers that the knowledge haunted him for days afterward, foolishly intrigued about what they could be doing on the footage.

"Wants to see... you?"

"Wants to see me get railed, yeah. I don't really get it."

Sky turns his head slightly to look at Rain out of the corner of his eye and immediately has to tear his eyes away. Because Sky does get it—gets why that could be appealing. He doesn't want to, but he does.

He's seen the marks that frequently adorn Rain's skin—purple, red, and fading yellow—visible sometimes around his wrists and forearms when he rolls up his sleeves; around his collarbones when he wears wide-necked shirts; and on his chest, belly, knees, and thighs when he comes over to go swimming. Sky pretends not to notice of course, but unwillingly his imagination provides him with images of Rain getting them and where else they might be found on his body.

"And how do you feel about that?" Sky asks. His mouth feels so dry.

"I don't know," Rain mutters softly, unease creeping into his voice. "I just wanted to know what it was like before I agreed to anything."

"I'm sorry I can't help you, but you know you don't have to do it if you're not sure about it. I'm sure P'Phayu wouldn't push you to do anything you don't want."

"He hasn't actually asked me to do it," Rain sighs. "He mentioned it's something he's curious about but doesn't bring it up because he's not sure he could really go through with letting anyone touch me."

"Then why are you entertaining the idea at all?"

"Because he spoils me," Rain says like it's obvious. "He does all the things that I want to try. He's never said no, so I want to be able to do something for him too."

Sky guesses he can understand that.

"But if we do it," Rain continues, "I wouldn't want it to be with a complete stranger, so we'd still need to find someone we're both comfortable around that we trust. But the only people we know like that are you and P'Pai."

Sky is almost dizzy with how suddenly and powerfully heat slams into his face. For a panicked moment he feels as if he's been seen through, but that's stupid. There's no way that Rain, always so conveniently oblivious, has figured him out.

"Absolutely not," he refuses too loudly.

"I was just saying. I wasn't suggesting anything!" Rain cries defensively. He turns to look at Sky, probably to check if he's angry, but Sky can't bear for Rain to look at him right now. His heart won't stop racing.

He physically turns Rain's head back around and chastises him. "Watch the road! And good, because the answer would be no!"




"Is there something on your mind, my Sky?"

They're lying in their bed, bodies heavy with fatigue. Prapai has been murmuring a stream of sweet nothings into Sky's ear in the post-coital glow, but Sky has yet to get flustered and silence him in irritation as he usually does.

Something is on Sky's mind—the conversation with Rain about threesomes.

"He said he just wants to watch."

"Have you really never wanted to share me with anyone else?"

Pai is on Sky in an instant, turning him onto his back to get a look at his face. "No, never. I swear," he denies, almost desperately. It kind of startles Sky a little.

He smiles at Pai indulgently and squeezes his shoulders. "Relax, I'm not accusing you of anything. And even if you did, I know you wouldn't. I was just wondering."

Prapai's body sags in relief before he rolls back onto his side. "Really, I never have. What is this about?"

For a second, Sky considers walking back on opening this can of worms—

"The only people we know like that are you and P'Pai."

—but this has been rapidly eating away at his sanity for the better part of a week and he's starting to feel a bit out of his mind for it.

"The other day Rain told me that he and P'Phayu could be considering having a threesome."

Prapai doesn't know what he was expecting to hear, but it wasn't that.

"That's surprising," he says after a beat. "You'd think they'd be too jealous for that."

He's witnessed Rain's barely contained tantrums at the track when people are too forward with Phayu—because Rain knows that's the last place to create a scene—and he knows Phayu. Phayu didn't let him meet Rain until after they'd formally started their relationship, and even then wouldn't let him around the boy without Phayu being there too, at least not before Prapai was hooked on Sky.

"I thought so too," Sky mutters contemplatively.

"But wait, what does that have to do with anything?"

"It was P'Phayu's idea. The way Rain told me, it sounds like he isn't thinking of participating. He just wants to see Rain 'get railed.' His words," Sky adds when Pai raises a brow at the choice of wording. "It made me wonder if you ever wanted to see me with someone else but never told me because you thought I'd take it badly."

"Again, no, I've never wanted that."

Sky offers him a weak smile and gives him a small peck near his chin.

"That's not all that's bothering you though, is it?" Pai asks.

Sky is still holding tension around his mouth and his brows, which Prapai recognizes are signs that Sky is stressed.

Sky's smile drops and he starts to turn away from him, but Pai prevents his retreat and instead rolls him the other way so they're facing each other. He uses his thumbs to massage slow circles at the corners of his lips and above his nose where his brows are slightly together. "Come on, let's talk," he encourages.

Sky wants to curse how wonderful Prapai is. Even if keeping secrets hadn't only ever brought them problems in the past, how could he ever keep any from him now when Prapai is so gentle coaxing them out of him?

"P'Phayu hasn't asked Rain to do it yet. Rain said he only mentioned that it's something he fantasizes about but doesn't talk about because he's too jealous to actually do it."

"That sounds a lot more like the Phayu I know," Pai says, feeling vindicated.

"So Rain asked me if I've ever had a threesome because he wants to know what to expect before telling P'Phayu it's something he'll consider if he ever decides he wants them to go through with it."

"Oh, is that what's troubling you? Did he bring up bad memories?" He reaches out for Sky to cradle him to his body but Sky pulls away.

"I'm fine," Sky reassures, appreciating the concern. "He also said if they do it that he doesn't want it to be with a stranger or a creep so we're the only options they have at the moment."

Pai barks out a laugh. "Obviously neither of us is going to agree to that."

"I told him that, but he was just making a comment. He wasn't trying to proposition us."

"Right, so what's the problem then?" Prapai has picked up on the apprehension coloring Sky's voice.

"It's— I—"

"He likes to film us sometimes."

"I get curious sometimes," Sky groans and balls his fists in frustration.

"About what?" Pai tries to get him to continue. Threesomes? Surely not.

Sky doesn't know how to answer that, how to neatly summarize all of his inner turmoil. "Rain," he finally settles on. That's what it all comes down to in the end, isn't it?

Bewildered, that's how Prapai feels. It's not the answer he was expecting to hear, but then again, none of this conversation has been going as he'd expect.

"Honey, I'm not sure I'm following." He takes one of Sky's hands in his own and laces their fingers together, giving his knuckles a gentle squeeze. "Are you trying to tell me that you're attracted to Rain?"

"Sort of? I'm sorry." Sky wants to bury his face under the covers. He thought he might feel better if he talked about this. He does not.

"What is there to be sorry about?" Prapai chuckles. "Who's never been attracted to their friends? It's totally normal."

"That's not what bothers me about it," Sky huffs. Of course he knows it's normal, that it doesn't mean anything. This is hardly the first time he's ever found himself sexually attracted to a friend. Probably won't even be the last as he continues to make new ones.

"Then what is it?"

"That it makes me a huge hypocrite!" Sky cries. "How many times have I gotten jealous and given you a hard time when I thought you were checking someone out or being too flirty?"

"But I like that you do," Prapai says, pleased, and kisses his forehead, loving when Sky melts against him and makes a soft, happy noise.

"Believe me, if the situation were reversed and you were confessing to me right now that you're sexually attracted to P'Phayu I would not be this understanding," Sky grouses.

Sky's not naive enough to believe that Pai never experiences sexual attraction to other people anymore just because he's in a relationship with him, but that doesn't mean he has to know about it.

"I know that, and that's okay." Pai smiles and holds him close. He is attracted to Phayu though, he wants to confess, but this is obviously not the time for that.

Sky takes a deep breath and tries to push through the last of his reluctance. "That's not all of it."

"Not all of what?"

"That's bothering me. You might owe Rain more than you think for us getting together."

"How's that?" Prapai asks curiously. Rain is the reason Sky was at the track the night they met. He's also the one who gave him Sky's number (even if Prapai had to trick him into handing it over), and the one who called him to nurse Sky when he got sick shortly afterward. How could he possibly owe Rain any more?

"Remember how I told you about the day that P'Phayu came to the faculty and I found Rain in the bathroom and had to help him get rid of his boner?"

"Yes? Though now that story has an interesting layer of context," Prapai teases.

Sky slaps his shoulder. "I know. That's when it started."

"When what started?"

"I liked it, telling him what to do. It turned me on," Sky admits. He left that part out when he first told Pai the story. "It made me realize I've always liked bossing him around and having him listen to me. Not just him. I'm on the student council, and even though it's exhausting, a part of why I do it is because of the influence I get to have over my classmates behind the scenes. I was still coming to terms with this when we met. It was only about three weeks later."

"So that night you were sexually frustrated and had just recently discovered how much you like being in charge. Wow," Prapai says, far too entertained and not even attempting to hide it, but Sky won't reproach him for it, as tempting as it is to. It's preferable over him being dismayed.

"Exactly. Who knows how that night might've gone otherwise—if you would've still found me unforgettable."

"I have faith you would've been," Prapai says, smirking, but still it makes Sky smile. "Is that what bothers you? That we might not be together if you hadn't liked helping Rain get off?"

"No. I started seeing Rain differently after that. And I've tried to keep myself from thinking about that day, about him, since he has a boyfriend now and I have you, but Rain never shuts up about his sex life and he and P'Phayu are always all over each other, so— so—" Sky hesitates. Throwing an arm over his face, he hides in the bend of his elbow and whines a confession. "I can't help but picture it."

"Picture… them together?"

"Yeah."

"Still, it's not anything you need to feel guilty about. I don't mind," Pai soothes, stroking up and down Sky's side. He gives him a moment, and then another, but Sky doesn't come out.

"Baby," he coos, taking Sky's arm and lowering it so he can look into his eyes. "Be honest with me. Are you tempted to offer yourself? Is that what you've been working up to admitting to me?"

Sky's expression shifts from pinched to regretful. He bites his lip and meets Prapai's eyes, gaze searching. For what, Prapai doesn't know.

"No," he answers eventually. "I'm positive I don't want to have sex with either of them. I just want to look. Instead of being tempted to offer myself, I imagine what would happen if I offered you."

"Me?" Prapai asks incredulously.

"I just told you I wouldn't be understanding if you were to tell me that you think about P'Phayu, but it'd be different if I gave you permission to. If I asked you to. If it was my own idea. I didn't understand it at first, but I do now—how P'Phayu might be so possessive of Rain but still be okay with sharing him."

Sky waits for Pai to say something, but he only blinks at Sky with wide eyes, gaping like a fish. "I know it's ridiculous," he grumbles.

Prapai struggles to come up with a response, still reeling from the turn this conversation just took. Sky would want to watch Rain get wrecked that badly that he'd consider having Prapai be the one to do it?

Suddenly, Pai's laughing in earnest, unable to stop. Somehow this startles Sky more than if he'd started shouting.

"You're not mad?" Sky asks anxiously.

"No, I'm not mad," Prapai says, once he's calmed down. "Why would I be mad? You know my past, Sky. You hate to be reminded of it. I also know yours. If anything, I guess I'm happy." He cups Sky's face and runs the side of his pinky finger along his jaw. "Happy that you've gotten to a place where you could ask for something like that."

Sky's face slowly breaks out into a wide grin. He beams, seemingly overwhelmed with adoration that Prapai is sure must mirror that on his own face. Then Sky is kissing him, sweet and chaste, and he comes to a decision.

"I'm not asking though," Sky clarifies, eyes still sparkling.

"Aren't you?" Pai can't resist teasing, but he's completely serious when he asks, "Do you want me to talk to Phayu?"

"I told you, Rain didn't actually ask us and P'Phayu might not even know he blabbed to me about it. If you just offer, he'll probably punch you. I would."

"Pfft, I can handle Phayu," Prapai assures.




To say that Sky never expected whatever you wanted to call this to actually happen is an understatement. Even with the discussions that followed afterward, it never fully sank in that they were really going to do this—all of them, together—until the four of them are in the guest bedroom of his and Pai's condo going over the rules one more time.

There aren't many. It was a unanimous agreement among the four that condoms are required. Per Sky's own request, nobody except for Prapai is allowed to touch him. Similarly, Phayu will touch no one but Rain. Rain requested not to be marked or tied down. Prapai set no boundaries for himself, but he or anyone else could set new rules for themselves at any time, no questions asked.

Sky watches as Phayu cups Rain's neck, stroking his fingers along Rain's hairline at the nape. His other hand has a firm hold of Rain's waist. Rain looks nervous and shy, glancing between Phayu, Sky and Prapai at the foot of the bed, and the room's surroundings. Phayu guides his face forward so their foreheads are touching, centering all of Rain's attention on him.

A thumb drags across Rain's cheek to the center of his chin and presses down, making his lip jut out. Rain seems to fall into a trance, his expression turning hopeful as Phayu swipes his thumb across his lip. Phayu, gentle and attentive, drops his gaze, darker now, to Rain's pretty mouth.

The moment he's kissed, Rain's hooded eyes fall closed and he lets out a soft sigh. It starts slow, the visible tension in Rain's stance gradually falling away as he presses closer, until he's wrapping his arms around Phayu's neck as he licks into Rain's mouth.

Sky can only sit there, enthralled. He's seen them kiss before, but not like this. They at least have the decency to not openly fool around in public, even if they don't take any precautions to not get caught.

It always felt wrong to watch. It still does, even with permission, even knowing he's going to be a witness to so much more than this, but Sky can't avert his gaze even as Phayu slides Rain's outer shirt off his shoulders.

Behind him, Sky feels Prapai skim his hands up his arms and under his sleeves to knead at his shoulders.

"Liking what you see?" he murmurs lowly into Sky's ear. Sky shivers and leans back, resting his weight against Pai's front. He knows it's not entirely a tease. Pai is also checking in with him to make sure he doesn't want to back out of this now that this is actually real.

"Yes," he replies honestly.

Prapai's hands make it underneath his T-shirt, long fingers fanning along his stomach, just as Phayu's hands slip beneath Rain's. Sky squirms, feeling arousal start to seep into his blood even with just this small bit of attention. He craves more, aware of just how tightly wound he is, has been increasingly as this day crept closer. He wants to be kissed too, but he also doesn't want to tear his eyes away.

When Rain's T-shirt comes off, Sky spots fresh bruises dotting his torso. Phayu indulges him and lets Rain take his off too, but as Rain tries to plaster his body to Phayu's again, Phayu stops him and guides him to the bed.

Rain feels his nerves return at near full force as Phayu sits him down at the head of the bed, hyper-aware of where he is again, but Phayu sits behind him and rubs his hands up and down the backs of his arms in comfort. The soothing gesture helps him settle a little.

But then Pai is crawling forward toward him after placing a small kiss on Sky's shoulder, slow and careful, as if approaching a prey animal. Rain feels frozen, knowing he must look like a deer caught in headlights by the way trepidation bubbles in his chest.

He's about to be kissed—he can tell by the way that Pai closes in and his gaze lowers to his mouth. Instinctively, Rain brings a hand up to cover Pai's lips to stop him. Pai's eyes widen in surprise and he stills.

"What's wrong?" Phayu asks, concerned. Strong arms wrap around him. "No kissing or did you change your mind? Do you not want to do this anymore?"

"No," Rain shakes his head. "I mean, no that's not it. I still want to. Just, back off P'Pai." He pushes back against Pai's face until he isn't crowding him anymore. Pai sits back and lets him have some space.

"What do you need, hmm?" Phayu noses behind Rain's ear, holding him close. "You want to be a good boy for Pai, don't you?" he asks, trying to arouse Rain's natural eagerness to please.

Rain looks away from Phayu to consider Prapai, who notices the way Rain's gaze turns appraising, lips pursing as he looks him up and down, humming. He can't help but feel just a teeny bit offended that Rain looks so unimpressed, even if he suspects it's an act—Rain's eyes are shining with mischief.

"No," Rain says decisively. He twists in Phayu's arms to look at him again and smiles cheekily. "Why should I?"

Phayu chuckles softly. "Rain," he says, trying to level him with the tone of his voice but it comes out too tender. Rain shivers anyway. It's the tone that's not quite a warning, more of a reminder that there's a time and place for misbehavior, but if Rain is going to summon the confidence to do this, he's not going to do it by playing the good boy.

After giving Phayu a quick peck, Rain leaves his embrace and stalks towards Prapai himself this time. Prapai straightens his legs out and spreads them in order to make room for Rain to kneel between them, but when he moves to take hold of his waist, his hands are swatted away.

"Aow," he makes a noise of offense, not knowing what he did wrong.

"Hands off," he's told sternly. "The only one who can touch me is P'Phayu."

Dumbfounded, Pai lowers his arms and lets them fall at his sides. Phayu doesn't look like he expected this development either. His face breaks into a crooked grin and his eyes gleam with amusement as he begins to shake his head.

Rain reaches for Prapai's shirt to undo the buttons, breathing steadily through his nose to calm his nerves. He can feel everyone's eyes on him and it's a lot of pressure, knowing that he and Prapai need to put on a good show. He can't help but look at Sky, wanting confirmation that this is really allowed.

"It's okay," Sky says, giving Rain's forearm a reassuring squeeze before he remembers that he's not allowed to touch. But to Sky's pleasure Rain doesn't reject him, just bites the inside of his cheek and nods, starting on the buttons.

"Hey, how come you let Sky touch you?" Pai protests.

"Be quiet, P'Pai," Rain scolds.

Pai turns to Sky with wide eyes and an expression that screams, Can you believe this? Sky can though; he totally can. He sucks in his bottom lip and laughs under his breath. He can only shrug in response.

He hadn't seen this turn coming, but he supposes he should have. It's no secret that the polite, well-behaved act is only for Phayu. Beyond the use of honorifics, Rain never shows Pai any proper respect. Irreverent ribbing and playful rebukes frequently spill out of Rain's mouth when they spend any amount of time together.

Once all the buttons are undone and the shirt is untucked from the waistband of Prapai's slacks, Sky helps slip it off his shoulders, where it falls to pool at his wrists. When he tries to pull his hands through the sleeves though, Sky stops him.

"So you're not tempted," he mutters impishly.

Prapai can't believe it. Sky's smile is bordering on wicked. Between him and Rain, he's being ganged up on.

Rain experimentally runs his hands across Pai's shoulders, from the crook of his neck to his deltoids. His skin is warm and smooth, and as Rain skims his fingers down his chest, he takes the time to study Pai's body, to examine what he's only ever observed in passing.

Pai is fit, just as much as Phayu is. But where Phayu is all sharp angles, there's a softness to Pai's curves that is equally as nice.

Once Rain has gotten down to his abs, he hopes to tease Pai further by running his hands slowly back up Pai's sides. When he explores the dips and arches of his ribs, Pai exhales and arches into his touch.

"He's sensitive on his sides," Sky explains. "But he's ticklish if you do it too lightly."

Rain is only human. How could he be expected not to do anything with that information?

Gleefully, he scrapes his fingernails very lightly around the subtle dip of Pai's waist and feels a sadistic thrill flash through him when the muscles beneath his fingertips jump and Pai lets out a grunt.

With great difficulty, Rain reins in his desire to keep tickling and refocuses his attention on Prapai's sides and what he can easily reach of his back until he has Prapai clenching his jaw and balling his hands into fists, the defiant look he's giving Rain communicating how much he'd love to pay him back for this treatment tenfold.

"Do you want to touch me, Phi?" Rain baits.

Prapai debates with himself whether to answer. Will he be rewarded if he replies honestly, or would it be better to stubbornly deny Rain a response and keep quiet like he was told to do?

The choice is decided for him when Sky rests his chin on Prapai's shoulder and sweetly says, "Answer the question, P'Pai."

"Yes," he grits out.

Rain cackles. "Wow, I just needed to calm down a little but I didn't know being mean could be so much fun. I can see why you like it now, P'Phayu."

Phayu laughs delightedly and comes up behind Rain, radiating something like pride. He wraps an arm around Rain's middle and showers kisses to the side of his face as Rain giggles and wriggles in his hold.

"This is very rude," Pai complains.

"Deal with it," Phayu dismisses him.

"Don't let his whining fool you. He likes being pushed around," Sky joins in the bullying. Prapai is helpless to do anything but shoot him a look of betrayal.

"Yeah, P'Pai?" Rain lights up, the beginning of a challenge creeping into his tone. He slides his hands up Prapai's knees, curving them around his inner thighs and digs in his thumbs dangerously close to his groin. Prapai's breath stutters and he lifts his hips reflexively, but Rain purposely avoids his dick. "How about you be a good boy then and maybe I'll let you touch me."

Prapai sucks in a breath. "Brat."

Rain sticks his tongue out at him. He can't argue with that. He is being a brat, and enjoying every second of it.

Now that Rain is armed with the knowledge that he likes a bit of manhandling, Prapai is grabbed by the scruff of his neck and jerked forward, eyelids growing heavy as Rain nips at his jaw. A moan gets strangled in his throat when Rain presses the flat of his tongue to the hinge of it. He can feel Rain's self-satisfied smirk against his skin just before he's sucking on his earlobe.

He's suddenly too warm, a demand building under his skin for more contact, to be closer, and instead of cooling his skin, the wet trail of Rain's tongue as he starts down the side of his neck only makes him burn hotter. Then Rain is pushing against his chest, guiding him backward into Sky's waiting arms.

Sky is mesmerized watching Rain work. With Pai slack against his front, Rain is so close that Sky can see every flash of teeth and tongue as he mouths at Pai's throat. Pai starts trembling in his arms once Rain finds the sensitive spot above his collarbones and Sky is so keyed up that every shake and shudder against him feels as though it vibrates through his own body.

He doesn't realize he'd been holding his breath until electricity races up his spine when Rain's fingers brush against his own on Pai's abdomen where he's been tracing his fingers along his abs. It's stupid how hard he is when he's not even the one being touched.

"Feeling good?"

Sky swallows, taking him a second to realize the question wasn't for him.

"Yes," Pai groans agitatedly when Rain gives his nipple a sharp tug.

Rain's hand glides up to cradle the back of his head and he leans in slowly, his breath tickling Prapai's cheek. It's clear he's about to be kissed by the way Rain's lips part, his head tilts, and his eyes start to close. Prapai surges forward, eager to meet him halfway, but their lips just barely brush before Rain's grip on his hair tightens and his head is tipped back.

Rain snickers happily at the whimper he's able to wrest out of him. "You like your hair pulled too?"

Pai gives his best effort at a reproachful glare, hoping that the desperation and want that he feels doesn't reflect in his expression. Rain's eyes soften around the edges in pity so he knows he wasn't successful, but it doesn't matter when his chin is cupped and he's finally being kissed.

Rain's lips part wetly, tongue teasing at the seam of his mouth to coax it open. A breathless, contented sound escapes Pai as he does.

Phayu scoots closer to Rain, kissing the jut of his shoulder blade and then the knobs of his spine. Rain now is such a stark contrast from mere moments ago. Rain when he's embarrassed and timid is lovely, too adorable to resist, but confidence always looks downright sexy on him. From what he's observed, he's not the only one who knows that now.

He's been conscious of the way that Sky has been watching Rain; like he's in awe, captivated. As if Rain is defying all his expectations. His expressive eyes betray the desire steadily blooming within him.

Naturally, Phayu knows what Sky's motivation is for taking part in this. When Prapai approached him to offer to work out an arrangement, he'd demanded to know what Sky would be getting out of it. Caught by surprise, he'd bristled at learning of Sky's budding sexual interest in Rain, but despite what the couple may think, Phayu is not a jealous man by nature.

Phayu is possessive, unquestionably—he likes to take good care of his things and doesn't share unless he can trust that the other party will treat his belongings with the same level of care and respect as he does—but jealous he is not. He has no reason to be. He's self-assured in his looks, his career, and all he's accomplished. He doesn't need to compare himself to others. This security extends to his relationship.

Beyond doubt, Rain is his. Phayu has his heart and loyalty as surely as Rain has his. Their bond is too strong to be easily threatened. He trusts Rain wholeheartedly, and he trusts Sky is just the same. He is wholly devoted to Pai. Even if Sky lusts for Rain, this will remain true.

Rain pulls back to catch his breath, but Pai, with his limited range of movement in his arms, follows him clumsily and captures his lips again. He spies Sky helping him extricate Pai's arms out of his shirt's cuffs, and to his delight Pai is good and keeps his hands to himself, only rolling his shoulders to relieve the stiffness in his limbs.

He gently pushes Pai off of him and fills his lungs with air as he reaches down to unbutton Pai's trousers. He purposely fumbles with the buttons, grazing his knuckles against Pai's erection, suppressing a smile when he tenses and hisses under his breath.

Rain would tease him about how desperate he is, but the state he's in isn't much better. He's only keeping it together because Pai not being able to touch him and letting him take control keeps his head clear.

Once he's eased Pai's zipper down, he tugs the pants down his hips, but he can only get so far with Pai sitting. "Keep the boxers on for now," he instructs, letting Pai take care of the rest.

He starts on his own pants and smiles when Phayu moves his hands aside to work them down his legs himself. "You've been perfect, darling boy," Phayu murmurs praise into his temple. Rain preens, unable to resist pulling Phayu into a sloppy kiss, sorely missing the feel of his mouth on him. The best part is that Phayu doesn't even chide him for not asking first.

When Rain returns to Prapai, he's guided onto his back as Rain makes himself comfortable again between his spread legs. Feeling Rain's fingertips traveling up his inner thighs, he perches himself onto his elbows to get a better view.

Rain dips his fingers underneath the leg openings of his boxers and caresses the skin there, creeping up and inching nearer to the join of his legs. Prapai plants his feet on the bed and draws his thighs up slightly, spreading them to encourage Rain to finally touch him where it matters. No such luck, of course. He grits his teeth in frustration when Rain's fingers slip back out.

Those fingers slide under the waistband at his waist, nails grazing along the sensitive skin of the hollow of his hip and again so close to his cock. Then Rain's pulling the waistband back and snapping it against belly, all while peering into his eyes.

"I can't touch you and you won't even touch me," he gripes.

"I am touching you, though," Rain says, rising onto his knees and leaning forward to hover over him. "What is it you want?"

He sighs exasperatedly. Rain knows that he's not shy to be direct about what he wants, which can only mean that Rain wants him to beg for it. "Touch my dick, please," he requests crudely, exaggerating the 'please' for effect, but his exasperation is poorly suppressed because Rain rolls his eyes at him.

Thankfully though, Rain presses the length of his hand to the front of his boxers, rubbing him through the fabric. Prapai bites down on his lip, exhaling shakily as his eyes flutter and his hips rock into the pressure of Rain's palm.

Rain's fingers spread over him, exploring the shape of him. His touch isn't teasing, more curious than anything. Prapai wonders why he delays in removing this final barrier so he can take a proper assessment until he notices Rain's focus is on the wet patch in his boxers. Now that his dick is finally getting some attention, he's leaking eagerly and Rain is spreading it, the royal blue of his boxers darkening to a deep navy.

It's a little embarrassing to realize that he probably could come from just this if he made the effort to, from Rain squeezing and palming at him through his underwear while he entertains in making a sticky mess of them.

"Come on," he whines.

"That's not how you ask for it, P'Pai," Rain chides, but he sounds pleased.

Phayu laughs quietly at his side but Rain's attention remains on Prapai, probably waiting for a rejoinder. Prapai intuits that these are words Rain is accustomed to hearing and is thrilled to have the opportunity to throw at someone else.

"Please," he acquiesces. "Touch me properly."

Seemingly satisfied, Rain peels Pai's boxers down his hips and off his legs, eyes only widening a fraction as the entirety of Pai's cock is unveiled. Pai is thick and long, which mustn't come as much of a surprise after groping him through the cotton of his boxers, but Sky knows from experience that it's different seeing it up close, slick and flushed dark as it stands up from his body.

Rain gets his hand around it and jerks him messily, and it's all slightly different than the way Sky does it of course. Most notably the strength of his grip and the frequency with which he rubs his fingers over the head. Despite these differences Pai hisses and spills over his fingers as Rain skillfully wrings sensation out of him.

Now Sky wonders how good Rain would be at giving head. Despite himself he hopes that he'll get to see it. Can he ask Rain to suck Pai off? Is that allowed? But even if it is, would it be weird to ask when he's been such a passive observer up until now?

"You know, I never said you couldn't touch yourself, just that you couldn't touch me. You could've taken care of this yourself if you were that desperate. You're lucky I'm so much nicer than Sky is," Rain says casually.

Sky narrows his eyes. Rain's clearly talking to Pai but he's only looking at Sky. And what he says is true... Rain really hadn't forbidden Pai from touching himself. Sky's sure he'd just assumed he couldn't because Sky never lets him when he's feeling cruel.

"Right? Aren't I?" Rain asks, quirking his eyebrows, and Sky knows then that he was right that Rain is fishing for more information about his and Prapai's sex life.

"Rain," Sky warns. "Stop."

Rain shrugs, his smile not wavering. "At least I know how big it is now."

"If you really wanted to know you could've just asked me," Pai laughs.

"It's more fun to embarrass Sky. And besides, I didn't trust you not to lie."

"Hey..." Prapai begins to retort but it dies in his throat as Rain descends down his body to settle on his stomach between Prapai's thighs. Starting an argument now to defend his honesty would be poorly-timed when Rain is softly sucking at the hard curve of his cock, massaging the underside with his tongue while slowly bringing more and more of Prapai's length into his mouth.

Rain almost chuckles at the low appreciative groan that he's able to wrest out of Prapai as he winds his hand around the base tightly, but he feels Phayu petting the backs of his thighs. He spreads them as best as he can and hums when Phayu's hands curve and drag up his inner thighs.

It's then that he feels it again. Sky is raking his eyes over him, transfixed, the weight of his gaze almost a physical touch. Rain shudders, then moans around his mouthful when Phayu's fingers dig into the bruises high up on the lower curve of his ass, the ones he can always feel when he sits down. Sky inhales, pupils blowing wider, but then their eyes meet and Sky looks away determinedly. He doesn't know what to make of it.

"Does Sky tie you up often P'Pai? The shirt wasn't my idea."

Pai doesn't answer right away, too dazed to process right away what he's being asked. "No," he says slowly, trying not to trip over his words. "He prefers—"

"P'Pai!" Sky cuts him off sharply.

Sky has an inkling of what Pai was going to say. Tying up Pai is a rare occurrence. Sky prefers to leave his limbs free because it's much more fun to see Pai wrestle with his self-control than against any restraints.

Rain laughs deviously at him before taking Pai back into his mouth. Sky doesn't know how he feels about Rain teasing him so boldly and at ease, only that he can't handle it right now, especially not with Rain looking him dead in the eyes as he jerks his boyfriend's cock against his tongue.

It's usually the other way around, Sky composed and Rain overwrought. He'd wanted to see the pliant, deferential side of Rain that he's seen glimpses of and that remind him so much of Pai sometimes, but he hadn't counted on Pai's nature actually being more submissive than Rain's. Because Pai is enjoying himself, greatly. His ardor hasn't flagged since Rain challenged him not to touch. All his huffy grumbling has been for show.

A sexually assertive, confident Rain… There are so many feelings about that to examine but it'll have to be later, otherwise Sky will drown in a flurry of horny confusion.

Rain pulls off and sits up. "Tell you what, P'Pai. Because I'm so much nicer than Sky, I'll let you touch me now."

Rain lets out an undignified yelp of surprise as he falls onto his back when Prapai abruptly sits up and pounces. Prapai wonders if he looks half as feral as he feels. It wasn't until Sky that he had the chance to learn how much of his own pleasure and satisfaction is derived from his ability to please his partner, so when the opportunity to is denied to him it's always a little maddening.

He reaches down for Rain's briefs and tugs on the waistband tentatively. Rain nods and together they shimmy them down his legs. Now that he's fully nude Rain shows the first signs of apprehension since Prapai first tried to take over the reins, but Prapai's not going to give him the chance to take back control so soon. He was good. He's earned this.

He props himself over Rain and carefully aligns their bodies. Rain's hands grip his arms, breath hitching and eyelashes fluttering as their dicks brush together. Lowering his weight onto Rain, he straddles his thighs and grinds down, the sticky slipperiness leaking from the both of them easing the slide.

Rain kisses him then, the angle a little awkward, sucking on his tongue and trailing his hands up his arms to rake his nails across his back. When those hands sweep down over his ass and squeeze into the meat of it, Prapai is helpless to do more than arch into the touch and groan brokenly into Rain's mouth.

Rain is trembling, pushing his hips up insistently, chasing more of that friction that's got his belly going taut. Prapai can only be grateful that he isn't the only one who's overexcited anymore.

"Wait," Rain pants, pushing at Prapai's shoulders. "Lube," he says to no one in particular.

Phayu provides, taking it from off the nightstand. Rain takes it but only presses the bottle against Pai's chest. "Prep me" is all he says before he's reaching for Phayu, pulling him down into a kiss.

Pai sits up, a bit bewildered. He can only guess that Rain began to feel too overwhelmed, hence the abrupt way he put space between the two of them.

"Rain?" he calls, needing to make sure Rain is really okay to continue forward.

"Go ahead," Rain says, a touch impatiently.

Sky comes up behind Pai, resting his cheek against his shoulder and winding his arms around his waist, squeezing. He can understand Rain's need to connect to Phayu because he too feels like he can gain some composure now that he can seek comfort in the warmth of Pai's skin and the steady up and down of his breathing.

It isn't enough though. Sky's whole body throbs with the need to do something, anything. Anything other than just sit here and choke on his own arousal. He slides a hand up to Pai's chest, the other dipping below to grasp his dick, stroking him as Pai sinks the first finger into Rain.

"Sky," Pai moans his name, tipping his head back. His free hand finds Sky's knee. "Everything okay?"

"Everything's great," Sky replies, and he means it.

"I love you," Pai then murmurs, and Sky shouldn't find it sweet, especially since he's getting ready to fuck his best friend, but the declaration and look of slavish devotion on his gorgeous face warm Sky's heart all the same. "Are you sure you still only want to watch?"

Sky hesitates to answer. He's absolutely sure he doesn't just want to watch, but he's equally sure that he's not nearly mentally prepared enough for more.

He has no idea how Phayu hasn't been touching himself the whole time, calm and collected from the beginning. But then again, Sky hasn't been either, he supposes, but it's not from a lack of wanting to. Mostly he's just been too paralyzed to, caught in a constant state of upheaval and adrift in a sea of pent up frustration.

Not Phayu though. He's only been watching with a stern expression, eyes fierce, jaw slightly clenched. Sky would wonder if he was angry if not for the occasional laugh when he's pleased with Rain and how obviously he was straining against his jeans, past tense because Rain is taking care of that now.

Rain has peeled his jeans open and is working his hand on him while Phayu sucks at the bruises marking Rain's chest and thumbs at his nipples. Rain keens, then starts squirming when Pai introduces a second finger. He looks... happy, kind of dazed, and Sky can't decide which of the other three he'd rather be right now.

"Yeah, I'm sure," he replies eventually.

"How many fingers do you want, Rain?" Prapai asks once Rain is taking both fingers easily.

"Give him three," Phayu answers for him.

Rain likes the burn so Phayu usually only gives him two, but Prapai is bigger than Rain is used to taking, and he's not as relaxed as he normally would be if it were only the two of them.

Rain tenses and bites at his lips once he's being speared by Prapai's cock so Phayu takes his hand and kisses his knuckles. "You're doing so, so well," he encourages, getting a watery smile in return. He doesn't do more though. As much as he'd like to distract Rain into relaxing, he needs to ensure that Rain doesn't ignore any serious pain signals.

Phayu kisses Rain's sweaty forehead and cards his fingers through his hair to soothe him when Prapai eases forward, pausing whenever Rain tightens around him so much that he can't manage to push forward any further. Once he's in most of the way, he changes tactics and starts rocking his hips, dragging his cock back and forth inside him until Rain starts to sigh at the stimulation and opens up around the intrusion.

"More," Rain grunts.

"More what?" Prapai asks breathlessly.

Rain bites down on his lower lip, and Phayu doesn't know if he's having trouble forming his request or if he's too embarrassed to voice it. He suspects it's the latter.

"Tell Pai what you need," Phayu tells him in the patient tone he uses to get Rain to put his desires into words.

Instead, Rain just wraps his legs around Pai's back, digging his heels in and rolling his hips up into Pai's thrusts.

Phayu chuckles, and because he's feeling especially soft for him today, he says, "He wants you to fuck him harder but he's too shy to say."

"P'Phayu!" Rain complains.

"What? You'll thank me."

On his next thrust, Prapai shoves all the way in sharply, bringing Rain's legs up further, and grinds deeply, no doubt trying to find the angle that will reduce Rain to an incoherent, babbling mess. Rain cries when he finds it, breaking eye contact with Phayu and tossing his head to the side as they fall into a frenetic rhythm.

Phayu leaves Rain's side for a moment, needing to sit up and take in the picture Rain paints. He's exquisite—flushed all over, baring his neck, practically glowing in his pleasure—and Phayu is overcome with how thick the air becomes with his want.

"P'Phayu," Rain breathes. "I want to be on top. Is that okay?"

"Of course it is. You can have whatever you want, Rain," Phayu says fondly. All he ever wanted out of this is to see Rain enjoy himself to the fullest, in whatever ways he chooses to do that.

Rain maneuvers Prapai onto his back again with surprisingly no pushback. He sinks back down on his dick after applying more lube and bites back a whine. It's not more than he can handle, but it's still a lot.

"God, Sky. You really take this every day?"

"Not every day," Pai says.

"P'Pai, don't," Sky cautions.

"Sometimes it's me taking it."

"Am I going to need to gag you?" Sky demands, mortified.

"Please? It's been so long since the last time. I miss it."

"P'Pai!" More heat floods Sky's cheeks. This has to be belated revenge for earlier. Pai doesn't even actually like being gagged all that much.

Rain giggles excitedly at their bickering, and Sky just knows he will pry further, but luckily it looks like that'll come later.

Rain rests his hands on Prapai's abdomen and gets to work. If he leans forward he can get some friction on his dick when he rolls down just so, so he does that while Pai helpfully grips his hips firmly and thrusts up from below. They find his prostate again and Rain's strength almost leaves his limbs. He drives his hips harder, hoping that his thighs won't give out too quickly, already starting to burn from the exertion.

Sky couldn't have imagined that this would be worse than when Rain was on his back. Rain willingly helpless and wantonly submitting to the attentions of another is certainly something, but he's glorious in motion.

His back is shiny with perspiration, arching when he pushes his ass out with every drop into Prapai's lap, erection bobbing with the movement. His pretty face is twisted in pleasure that looks so much like discomfort, eyes half closed as he rides the waves of sensation that must be washing over him. His mouth is agape, gulping air and panting out shaky moans. Sky wants to feel them against his teeth so bad he aches with it.

A tingling rush courses through his body when he finally permits himself to kiss Rain. He gasps against Sky's lips, but he's quick to reciprocate, mouth hot and firm against his. It's no wonder why Phayu's so obsessed with Rain's mouth, his lips feel as full and soft as they look. It's clumsy, since Rain is still bouncing, but Sky keeps kissing him, beginning to feel a familiar pleasant buzzy numbness in his lips. He drinks in Rain's mewls as their tongues stroke wetly against each other until Sky inevitably needs to pull back for breath.

He isn't prepared for the dreamy look on Rain's face or the breathy, needy way he calls his name. Neither is he ready for the darkness of Phayu's eyes as they roam over Sky's face and down to his hands that are tightly winding into the comforter, clenching so tight his knuckles are white.

He almost feels like he's going to faint when Phayu reaches across to him and circles a hand around his wrist. Slowly, he brings it up to just under the base of Rain's throat and presses Sky's palm against it before letting him go. Sky feels a nervous, incredulous laugh-sob threatening to erupt from deep in his chest at the realization that this is an invitation to touch Rain.

Logically, Sky knows he's had permission all this time, but the active encouragement is the final push he's needed to curve his fingers around Rain's neck to feel the rumbling of his moans and the jackrabbiting of his pulse. He slides his hand down and cups his hand over one of Rain's pectorals, squeezing around it and marveling when his nipple tightens under his palm. He rolls it between his fingers, making Rain whimper, and Sky is dying to know if they're as sensitive as his own.

His hand continues its descent, following the trail of marks that lead down to Rain's knees. The muscles of his stomach ripple underneath his fingertips as he skirts around Rain's dick.

"Sky, please," he pleads, high and desperate. "I'm so close."

Sky gets impossibly harder at the supplication. Rain could easily get himself off, or even ask Pai or Phayu to do it, but it's Sky he's begging so sweetly. He takes Rain in hand and strokes, tightening his grip at the tip like he remembers Rain likes, and it's only moments before Rain freezes and comes with a full body shudder.

Prapai cries out at the sudden almost painful clench of Rain's body around him as he releases. Even if he wanted to, he's almost powerless to stop his own orgasm, the rhythmic contractions of Rain's walls practically tearing it out of him after the sight of Sky bringing him off drove him to the edge.

Sky reaches for a pillow and removes the pillowcase to wipe his hands on it. They were going to wash it afterwards anyway. He also cleans off Pai's stomach when Rain gathers the strength to get off his lap.

Pai sits up and removes the condom, tossing it in the trash. He kisses Sky lazily then, expression a bit sleepy. "Let me take care of you," he murmurs, hand cupping him through his shorts and squeezing sympathetically.

Sky's been hard for so long that it isn't helping to take any of the edge off at all. Pai rolls onto his stomach and sinks down, reaching for his waistband, and Sky is about to protest because they're not alone, but falls silent at the sight of Phayu positioning Rain onto his hands and knees at the edge of the bed. Phayu immediately pushes into Rain like a man starved, and the overstimulation overwhelms Rain, dropping him to his elbows. His head lolls, eyes unfocused, but Sky clocks the moment Rain sees Prapai freeing his dick from its confines. His mouth drops open and his eyes widen a little.

Pai's mouth is warm, wet, and enthusiastic despite the fatigue that Sky is sure is settling into his bones, and Sky knows that between the ministrations of that talented tongue and Rain's greedy eyes following every move, this won't take long. Rain whimpers as Phayu's hips pick up speed and his thrusts go erratic, and Sky comes seconds before Phayu does, convulsing as he feels every one of his nerves rending. He impulsively pulls Prapai's head back with a fist in his hair to spill over his tongue and does not allow himself to examine why.

All four of them collapse to the bed in a tangle, panting and dazed. Sky feels the tendrils of an awkward tension creeping in as they're catching their breaths when Rain throws his head back and guffaws, dissolving it instantly. His laughter is infectious, and soon they're all giggling tiredly, until the exhaustion wins out at last and they drift to sleep.




A few days later, Sky and Prapai are getting ready for bed when Sky hears the chime of a notification on his cellphone. Prapai passes him his phone as they get settled against the pillows. He pulls him into his arms and looks over his shoulder as Sky swipes the screen open. It's a text message from Phayu and Sky makes a small sound of alarm at first that something might be wrong with Rain, because Phayu rarely texts Sky. The message itself only reads, "Rain chose this one for you," but there's a link to an encrypted file sharing service.

Hesitantly, Sky taps the link and downloads the file. He sees that it's a video file and he feels his heart beat faster. Biting his lip, he opens the file and it begins to play. The sound of Rain's moans fill their quiet bedroom and Prapai's arms tighten around him at the same time Sky drops his phone, his hands flying to his cheeks. He quickly snatches the device back up and scrambles to close the video.

Prapai chuckles against his shoulder and presses a kiss against it. "I guess Rain and Phayu decided you should get to have a memento."

Sky huffs. Now that he knows what it is and can think about it without the sounds of Rain's pleasure echoing around in his head, he can see this for the gift it's clearly meant to be. He looks back at the message Phayu included with the file and runs his thumb across the text. Rain chose this for him. Rain selected a video of him and Phayu with Sky in mind, wanting him to have this. Phayu had been the one who sent it to him, giving him explicit permission to see this, to keep it.

To enjoy it.

Prapai is already running a hand up his chest. "So, wanna watch?"

Sky opens the file again and hits play.
