Summary
Boothill huffs out a breath, hot against Argenti’s neck. When Argenti’s breath hitches, Boothill grins, noses up to kiss behind her ear. “What’sa matter, darlin’?” She murmurs, heat running through her. Her mechanics shift and whirr, fingers lightly tapping against Argenti’s solar plexus. “Can’t I just look?”

Summary
Argenti dreams of it, sometimes. The flash of cameras, the harsh lights, the soft scrape of ice under his blades. The weight of the medal around his neck. In his dreams he’s at the top of the podium. In his dreams, he lands that jump. In his dreams, he does media interviews, gives autographs, competes again and again and again, getting better and better, closer to the greats of their time.
When he wakes up, it takes him a moment to greet reality. He basks in the glow of success for a moment before the grief kicks in and the daily aches of his body catch up to him. His ankle and knee complain, but he ignores them, swinging his feet to the ground.

Summary
A dare. It had been a dare, and Argenti was nothing if not willing to prove that his dedication to The Beauty was above reproach. But, holding the fabric in his hands, hearing the hum of the Express around him and the slow, steady pulse of music in the party car, he wavers. There’s not much to the fabric; half of it feels like mesh, catching on the callouses and scars on his palms. Still—Boothill is here, equally shoved into one of the small guest rooms to change, he assumes, and Argenti can’t bring himself to let the ranger down.
Mesh tights. A leather bodysuit that will barely cover his chest, and doesn't even cover his ass. It feels vulnerable to even consider wearing them, but—he can’t give up now. He can’t.

Summary
Argenti has plenty of opportunity to look at him, properly look–the tension around his eyes are gone, the ever-present faint scrunch of his nose. He’s slack-jawed, hair pulled into a careful queue. He’s beautiful, is what he is, chapped lips and all.
Boothill’s metal body is splayed out. Hands bound above his head, crossed at the wrist. Flat on his back, neck supported by a thin pillow. Legs loose, parted around Argenti, everything on display. He’s not plugged in–had charged what he could during their downtime. The sleep is for his mind, but–he’ll be waking up soon, internal clock never variable. Argenti doesn’t feel guilty for starting early–his cowboy isn’t losing sleep.

Summary
He can still smell roses. His junior had visited, a knight in tow, and they all smell the same, really. The smell is burned into his nose and he takes another slow breath as he grabs the front of his slacks. Every inhale stokes the simmering fire hotter. It takes him far longer than he’d like to admit to work out what’s happening as he leans back there, massaging the front of his pants like it’ll help. The incandescent tug of his instincts to track that rose scent and take what he wants wars with the knowledge that who he wants is not at the other end. Sharp teeth draw blood, canines digging into his lower lip, and he sucks a breath in only for it to shudder through him. The curse surges with it, tugging at the edges of his sanity, and—he can’t go out like this.

Summary
“I was thinking,” she says, speaking over Phainon when she gets out a dangerous. “Would you be open to me joining you for one of your videos?”
Phainon stops. Just—stops. Her breath catches, her thoughts skid to a halt, and her eyes almost bulge out of her head. She tries to swallow, chokes on it, and Mydei snorts out a laugh at her expense.
“Is that so surprising to you?” Mydei’s eyes glint when Phainon glances over, and she quickly looks away.

Daisies on your Nightstand by spacebuck

Summary
“I heard you whimpering last night” isn’t exactly something you can say to someone over your morning coffee. Mydeimos knows that Phainon has nightmares—they’d talked about it before, before they’d moved in together, and she’d brought it up periodically since. Often as excuses to not go for their early morning run, but that’s neither here nor there. Still, it’s been a while since they’d plagued Phainon like this. Mydei is—she’s concerned.
She’s never crossed the threshold of Phainon’s room for this sort of thing but the thought had occurred to her to shake her best friend awake, to rescue her from whatever had plagued her. But, every time she’d approached the door, hesitated outside, the sound had settled to just the soft puff of breath. If the creaky floorboards of their shared apartment were enough to pull Phainon from whatever horrible things her mind was putting her through, Mydei resolves to never fix them.
That doesn’t solve the root of the problem, though.

Summary
“Yer sure about this?”
Boothill’s hat is dipped low over his face, hiding his expression. Argenti can picture it from experience—brows drawn tight, hesitation pulling at the corners of his mouth.
“Of course,” Argenti says, softening his tone. If he announces Boothill’s uncertainty to the world, the other man might decide against indulging Argenti further. “Your grace and precision during battle is far beyond the level of dexterity required for something like this—though, it is known to take some time to grow accustomed to the sensation, so I will stay close and catch you should you fall.”
For a moment Boothill flusters, ears tinging purple, fans whirring loud, then he’s settling again and lifting his chin. “Fine,” he says, sharp. “Fine, but if both’a us fall that’s on you.”

Summary
He’s never been this short with another, even one on the wrong side of history, but Boothill’s hands have worked his pants open and it’s difficult to give the conversation his full attention. There’s a crackle over the line, then a firm, ‘Please hold’, so Argenti takes the opportunity to look down.
Boothill’s eyes glint up at him, scrunched up like he’s smiling. He licks his lips, and pulls Argenti’s half-chub free before sucking it into his mouth. His eyes flutter closed, bliss written in the lack of tension between his brows, and Argenti drops a hand under the console to cup the back of Boothill’s head. His hair is silky, sliding through the the metal and leather of Argenti’s gloves. He wishes he’d thought to take his gloves off before all of this had begun.

Summary
Argenti doesn’t know how it happened, but at this point he doesn’t want to break the kiss to ask. Boothill moans, shaky and soft, and Argenti pulls back to breathe—and the near-indentical face blinking at him grins back when he smiles. “Your Boothill is sweeter than mine,” she says—this alternate-universe him with her spit-slick lips. “Mine would have kicked up a fuss by this point.”

Summary
The One and Only was better equipped for this—a chair he can sit upright in, his cloths and oils easily at hand. But this isn’t there—this is a hotel room in a humid, coastal city of an uneasy world, and Argenti had been wearing his armour plate for far too long.
And now the low rumble of Boothill’s praise has sunk into his bones, leaving him shivering, helpless. His belly twists, and he knows he’s reacting physically as well. He knows his face is hot, knows that any other person would feel the aching throb of his cock against their thigh, but Boothill, tactile as he is, doesn’t activate that part of his brain unless he decides he needs to. And, surely, this isn’t one of those times.

Summary
Argenti sits, pats his thigh once his gloves are securely in place, and Boothill settles his cheek against the spot after shuffling a little closer. “Sweet boy,” Argenti says again, stroking his fingers over Boothill’s cheek, up into his hair. Then he tightens his grip and tugs, and Boothill’s shocked, heady moan is music to his ears. He tugs again, then maintains the tension, keeping Boothill’s hair taut against his scalp. Boothill grabs his calf, one hand wrapping around the breadth of it, and clings to him.

Summary
“I think,” Phainon says before Anaxa can bite back. “That he shouldn’t get a say if he’s acting like this.” It’s pointed, but it works – Anaxa sits back in his chair, thoughtful look on his face. It’s taken Phainon a while to get used to this. Anaxa’s sharp wit has been honed into a blade, and Phainon’s rebuttals have been soft until recently. Worried about breaking, ignoring the fact that it’s the point of these duels. He’s a quick learner, but kind-hearted. Not soft, never soft, but overwhelmingly good in a way that should make Mydei cringe. But, here they are – one year in.
A soft, agreeing sound escapes Mydei. “He can wait, then.” -

Summary
“Did’ja bring us all the way back ‘ere for a reason?” Boothill rumbles, sleepy eyes sharpening with every heartbeat. Argenti hadn’t even considered this – he’d taken his favourite booth out of habit, and yet, here they are. Hidden from all attendants.

Summary
Argenti’s breath shudders out on a whine, and Boothill laughs - laughs on a puff of breath. “Ah - I can’t get the angle I like,” Boothill drawls, and when Argenti swallows it’s dry enough that it clicks. “It’d be easier if you were here.”
Argenti wants that - craves that, even. The throb of his cock matches the rapid flit of his heart and his pants are far too tight. He can’t bring himself to move the phone, though. The hologram it’s projecting of his beloved is sitting right on his belly, right where he can get the best view. “You’re so cruel, my Prince,” Argenti says, and Boothill laughs–laughs–a crackly, gravelly thing. “Where are you now?”

Summary
Boothill turns Argenti around and presses her against the hallway mirror. The plush curve of Argenti’s ass rubs up against Boothill’s belly, and Boothill nudges her ankles further apart until Argenti’s skirt starts to roll up her thighs. “You’ve been so, so sweet for me,” Boothill says, and Argenti grabs her hand and tries to drag it down her belly.
When Boothill resists, Argenti whines, and the sound is so, so beautiful that Boothill wants to make her do it again. “Are you wet for me? I know you are,” Boothill continues, dragging her lips over Argenti’s throat. “I want you to watch. Yer gonna see exactly how wet you are, and what yer reward is.”

Summary
His teeth ache. It’s getting closer, but the Trailblazers are still excitedly talking to his cowboy, and the diviner – Qingque her name was – tugs at Argenti’s wrist to get him to lean down. “Does he know?” She whispers in his ear. Before he can pull away, she grabs at the collar of his shirt, just above where the armour stops. Sniffs, pulls a face. “I’m surprised you’re out here. Take him home.”
“I’m not-we’re not-” Argenti stutters, caught off-guard for what feels like the first time in the better part of a decade. He shakes his head slightly, and it dislodges her grip. “It’s not like that.”
“You’re in rut, stinking up the place, and you’re with him."

Summary
Argenti goes very, very still. In his armour it’s hard to even see the rise and fall of his chest. Only the slightest sway of one curl gives it away, shifting against his breastplate. Then his head cocks to one side. It’d be cute if the look in his narrowed eyes wasn’t so… dark. “On your knees.” It’s a command, not a suggestion. His hand starts to move again, pulling at the straps of his vambrace. The armour piece slides free, gets set on the portable rack Argenti’s set up.
Before he can start on the other one, Boothill says, “Make me.” He expects hesitation. He doesn’t get it. Argenti is in front of him a moment later, bare hand clasping the back of Boothill’s neck. It’s right where metal meets flesh, that sensitive, scarred line weakens Boothill at the knees. Argenti knows this – applies pressure and Boothill caves with almost no resistance. His knees hit the ground with a thud that aches bones he no longer has, the shockwave of impact radiating through his sensors.

Summary
“You’re touching me,” he says, and the smile gets wider.
Argenti blinks once, twice. “Am I?” That big hand on his back draws him closer still, tugs until their bellies are touching with each shift in the current, each drag of the net. Another tentacle slides up, tracing over the line of Boothill’s fins and he doesn’t stop Argenti. This, he thinks, this is what he’d been craving. Contact, warm physical affection, something he’s only heard about.
“Most people don’t get a chance to,” Boothill continues, digging the tips of his claws into Argenti’s skin. Pinpricks, probably, but he knows he’s made his point when Argenti’s mouth falls open, when the gills on his throat flutter and shake.

Summary
Argenti signs off his first meeting with a click of his mouse, and a sigh once the audio has cut completely. He clicks his tongue once, types his thoughts down before they slip his mind, then stands. A light stretch has his shoulders clicking. A quiet rattle catches his attention.
When he glances to the couch, dark, pleading eyes meet his. “Oh,” he says softly, a thrill running through him. “Did you want something?”
Boothill nods, wiggles his hips. It’s about all he can do with how he’s bound, and it rubs his probably-hard cock against the arm of the sofa. His mouth drops open, eyes closing. He’s so pretty when he’s bound, when he’s desperate. Argenti checks his watch – he’s got a bit of time.
“Mmh. Remember, this is for me, not for you.” The sound Boothill makes is encouraging, but it turns into a squeak as Argenti crouches behind him and parts his cheeks. When Argenti leans forward, blows a stream of air over Boothill’s wet hole, his submissive squirms against his restraints.
