“What are you doing?” said Kirk when Spock started taking off his shirt.

“The Seikkerts will not release us until we perform the ritual,” said Spock, as impassive as ever as he unbuttoned his regulation slacks. “Therefore, the logical course of action is to comply with their demands.”

“What?” said Kirk. “No! No way. We’re not doing-that.”

“We do not have a choice,” said Spock. “There is no alternate course of action.”

“There totally is,” said Kirk. “We’re going to sit here-not having alien-mandated sex-and wait for someone on the Enterprise to notice when we miss our check-in, and then they’ll mount a rescue mission to bust us out. Simple.”

“A rescue mission would endanger the lives of our shipmates,” said Spock. “To willingly risk casualties when such can be avoided is-”

“Illogical. Yeah, yeah, I get it,” said Kirk.

“No,” said Spock. “I was going to say ‘imbecilic and unnecessary.’” And then, oh god, he took off his underwear, which left him naked. Kirk didn’t want to see that.

“Dude, put it away, I don’t want to see that!” said Kirk, turning his head. If he peeked, it was just to see whether his dick was bigger than Spock’s-which, by the way, it so was (by a little bit), because Kirk’s dick was awesome like that.

“Stop behaving like a spoilt child and remove your clothing,” said Spock, making that I’m-so-disappointed-with-you-now-stop-being-a-jackass face that invariably made Kirk think of his mother (which was the last thing Kirk wanted to think of in this situation-the second-to-last thing being sex with Spock).

“I’d like to go on-record as saying that I’m doing this under duress,” said Kirk, shucking off his shirt.

“Duly noted, Captain,” said Spock. “To make this experience less objectionable to you, I will allow you to penetrate me during the ceremony.”

Kirk choked a little on his tongue and almost fell over as he was removing his pants.

“Jesus!” said Kirk. “You can’t just go around saying things like that!”

Spock ignored him and picked up the bottle of lubricant the Seikkerts had left on the bed. For the first time during all of this, he looked uncertain.

And, okay, Kirk might not have been the classiest guy in the world-starship-whatever-but he wasn’t heartless, either. He’d shoulder his fair share of the humiliation.

“Give me that,” said Kirk, gesturing towards the bottle, and Spock did.

“Lie down flat on the bed,” said Kirk, and Spock did that too.

Spock lay down on his back and Kirk should have told him to roll over onto his stomach, should have told Spock he didn’t need to see Spock holding up his legs for him or watch the hot, embarrassed flush of green crawling down Spock’s pale chest, but Kirk didn’t.

The top of the bottle sounded very loud when Kirk snapped it open, and the short gasp Spock made when Kirk nudged a slippery finger into him was even louder.

“Okay?” Kirk said.

“Do not worry,” said Spock. “I will just lie back and think of the Federation.”

“Was that a joke?” said Kirk. “You’re making jokes now?”

“I attempted to add levity to the moment in order to lessen our mutual discomfort, yes,” said Spock, then jerked, grunting, as Kirk slid a second finger into his asshole.

Spock let go of one of his knees to squeeze at Kirk’s shoulder (his hand was damp and hot against Kirk’s bare skin, not that Kirk noticed) and told him, “P-please refrain from doing that without prior warning!”

“Sorry,” said Kirk, crooking his fingers, and then his fingertip brushed against something inside Spock that made Spock’s whole body surge up against him.

“What the fuck was that?!” demanded Kirk, because according to all the anatomy classes he’d ever taken (and he’d taken many, as bodies were a special area of interest to him), that shouldn’t have just happened.

Spock panted, trying to regain his composure, and said, “I inherited several features of human physiology from my human genes. Apparently, the prostate was one of them.”

“Apparently?” Kirk said.

“I did not know,” said Spock.

“Well, you learn a little something every day, I guess,” said Kirk, and Spock gave him an extremely unimpressed look that Kirk delighted in ruining when he brushed against Spock’s prostate again.

Spock squeezed his eyes shut, writhing, rocking his ass down onto Kirk’s fingers, so fucking wanton and Kirk hadn’t known Spock could be like that.

Kirk’s dick was suddenly a lot more interested in the proceedings-which was vaguely horrifying, to be honest, but Kirk wouldn’t feel too mad at his libido if it meant getting through this quickly.

“You ready?” said Kirk, and Spock said, “I…do not believe you would injure me if you entered now,” and that was all the permission Kirk needed.

Kirk hauled up Spock’s leg-the one Spock had let go of earlier to grab onto Kirk’s shoulder-and used his free hand to lube up his cock and guide it to Spock’s entrance, to slide in slow and not think at all about how tight a fit it was or how Spock’s thighs tensed or how Spock’s dick was hard and wet against his stomach.

Spock bit at his lower lip: tried not to make a sound when Kirk fucked into him, swallow the noises down, but Kirk heard them anyway; Kirk felt Spock’s fingers digging into his shoulder so deep they’d certainly leave bruises, and he hoped to hell Bones wouldn’t want to do a physical on him after this because those would be hard to explain.

Kirk looked down at Spock’s face, at Spock’s tiny asshole clinging around his girth, and thought: I have to be careful.

Kirk had to restrain himself no matter how pretty Spock looked underneath him or how much he wanted to fuck in rough, see Spock’s asshole puffy and aching and dribbling come (which, fuck, Kirk should really not be thinking about). Spock deserved better than that; and besides, they couldn’t let people know they’d done this-no one could suspect that of them, it wouldn’t be-

And at some point Spock had stopped whimpering in pain and started whimpering for another reason entirely, Kirk’s dick rubbing against that sweet spot just like Spock needed it and Spock’s hand had slid from Kirk’s shoulder to his back, blunt nails scrabbling against Kirk’s spine and all Kirk’s good intentions crumbled when Spock whispered, Harder.

Kirk thrust harder.

Kirk leaned in and bit, soft, at a pectoral-rolled his tongue flat against Spock’s nipple, teased the tip of it, and Spock spread his legs wide for him and said, “Captain, please, I need-”, babbling, undone, and Kirk said, “I think it’s alright for you to call me ‘Jim’ now, Spock. Unless you think that’s a breach of protocol?” but Spock didn’t get the chance to answer that because by then he was coming, warm spurts of jizz sticky on his chest and belly and Kirk hadn’t even touched him, Spock had wanted it so bad that he’d come without a hand on his dick and, okay, Kirk was totally straight-this incident notwithstanding, what with the extenuating circumstances and all-but even he had to admit that was just goddamn sexy.

Spock lolled against the mattress, boneless, and Kirk wrapped Spock’s legs loosely around his waist: pumped his hips forward, his balls slapping against Spock’s ass, his cock buried in all that welcoming heat and Kirk grunted and came, swearing, inside Spock’s ass (all sloppy now with spunk and lube).

The sound of a throat being cleared drew Kirk and Spock’s attention to the side of the room.

“Ah, if you’re done now-” said Sulu awkwardly from the newly-opened doorway, “-we’re here to rescue you.”
