Kirk grunts as pleasure sweeps through him. His muscles give out and he slumps down against Spock's chest before reaching up lazily to unfasten the restraints currently fastening Spock's arms to the headboard.
Released, Spock's arms curl around Kirk, warm hands stroking his back. Kirk shifts further into the touch, rubbing his cheek affectionately against Spock's chest. "That was incredible," he mumbles.
"I am gratified that you enjoyed it," Spock replies, and Kirk raises his head, shifting to look at him.
"About that," he says. "You've been so accepting of me and my kinks that I feel like I should return the favour. Is there anything you'd like us to try?"
Spock's fingers run gently through his hair. "Your pleasure is all I require," he says.
Kirk frowns, a little disappointed in spite of himself. "So there's nothing you'd like? Nothing I can do for you?"
Spock's gaze skitters off to the side. "Well…"
Bingo, Kirk thinks. "Anything at all," he coaxes gently. "Just say the word and we'll do it."
Spock swallows. "Last week," he begins quietly. "You entered the bathroom as I was exiting the shower, and struck my left buttock with your hand." He pauses briefly, then adds, barely audible, "It was… unexpectedly stimulating."
It takes Kirk a few seconds to sort through that. "You want me to spank you?"
The question is purely curious, but Spock curls in on himself as if scolded. "It was just a thought," he says. "If you would rather not-"
"No!" Kirk interrupts, before he realises that might be taken the wrong way. "I mean, if that's what you want, then we'll do it. It's no problem at all." It isn't a kink he's ever indulged in himself, but he's spent months trying to get Spock to relax and open up about sex, and this is a huge step forward. If Spock wants to be spanked, then Kirk will give him the best damn spanking of his life.
He gives Spock's ass an experimental swat and smiles as colour spreads across Spock's cheekbones. Yes, he thinks. This could be fun.

The next day, when Spock comes back to their quarters after a shift in the science labs, Kirk is ready for him.
"Computer, lock door," he orders, leaning casually against the wall. Then, to Spock, "Drop your pants and bend over the desk."
Spock blinks at him, looking uncertain. "Jim?"
Kirk pushes himself upright and gives Spock a reassuring smile. "Just trust me," he says.
Spock tilts his head, but obeys, carefully removing his boots, then his pants. His fingers hesitate at the waistband to his underwear, but when Kirk nods he removes those as well. Then he steps over to the desk and bends over, resting his weight on his hands.
Kirk circles around behind him, admiring the view. Slowly he reaches out and runs a hand over a slim buttock. "If you want me to stop, just say so," he says.
Spock nods, but remains silent. Kirk caresses his ass a moment longer, then abruptly pulls back his hand back and brings it forward sharply, striking Spock square on the left buttock.
He leaves his hand there briefly. "Again?"
Spock nods, and Kirk brings his hand back for another smack, this time to the right buttock. He alternates for the next few slaps, then smacks both at once.
By this time his hand is beginning to sting, and he pauses again, taking in his handiwork. The slaps have brought blood rushing to Spock's ass, turning it an attractive shade of green. He looks round to see how Spock is reacting, and sees him leaning heavily on the desk, his eyes squeezed shut. For a moment Kirk feels a flicker of concern, but then he looks down and sees the erection standing out from Spock's body. Oh.
He smiles wickedly as he rubs a green buttock. "You really do like this." He leans forward and adds, barely above a whisper, "Touch yourself."
For a moment Spock does not react, but then he obediently moves one hand down to his erection and begins to stroke. Kirk watches for a few seconds, then draws his hand back and resumes his spanking.
Spock's breathing becomes more and more erratic as they continue, caught between the two sensations. His free hand digs into the edge of the desk, the other moving faster and faster until he gasps suddenly and comes.
Kirk gives him one more smack for luck, then turns him and draws him into a hug. Spock buries his head in Kirk's shoulder, still breathing heavily.
"Did you enjoy that?" Kirk asks, stroking his back.
Spock nods, then pulls back enough to meet his eyes. "Yes," he says. "Thank you, Jim."
Kirk smiles. "We'll have to do it again sometime." And not just for Spock's sake, he thinks. He hadn't expected it to be so… stimulating.
He slips a hand down Spock's back, caressing the now tender buttocks, and lets his mind drift idly towards next time.
