You know what? Why not.

Kadlawen gracefully turns, encircles his arms around Ateshai’s midsection, leans upward a bit,

and

kisses

him.

He is, as it transpires, a quite literally inhumanly excellent kisser- the kiss manages to avoid awkwardness entirely, instead achieving a level of effortless passion and precision that would make Olympic ballerinas emerald green with envy. The ‘physical skill’ bit he’d mentioned amongst his familiar blessings presumably applies. 

(He also- as would be moderately less relevant for people with ordinary senses, but is likely to be fairly significant for a Shifter- smells really, really good.)

Ateshai is an incredibly bad kisser! But enthusiastic, at least.

Kadlawen can totally make up for nearly arbitrary incompetence on the part of people he’s kissing! He’s very convenient, that way. 

Eee! Eee! Eee! More inarticulate nonverbal squealing! Ateshai is great and everything is great and he really should’ve done this sooner!

...Ateshai has no idea where to put his hands! This might be a problem!

Kadlawen is tragically unaware of this internal conflict! He’s just going to keep moving his hands around in precise little dances and circles around Ateshai’s back, inducing a substantial degree of melty, pleasant, and vaguely erotic shivering! 

Even without external prompting, however, Ateshai can presumably still anticipate that the answer would be ‘wherever you’d like’.

Yeah his hands are sort of going to just flutter indecisively, how does he do this kissing thing ahhhhhhh.

(It's a good ahhhhhhhhhh, but also: ahhhhhhhhhhhh).

- Kadlawen eventually notices this.

And, since, he is so done with being restrained, he gently grabs one of Ateshai’s wrists, and fluidly places the associated hand on his derrière.

Then he'll be treated to what Ateshai looks like when he turns into a blushy goo person! (Not literally, but there is a significant amount of blushing going on).

Ateshai is way too busy being kissed by the magically-assisted best kisser on the planet to be a blushy goo person. Perhaps additional kissing will ameliorate this issue.

Nooooo he's pretty stubbornly a blushy goo person. Additional kissing in fact seems to make the blushy goo condition worsen!

Oh no! How terrible! This complication ought to be solved by the application of... additional kissing!

They should probably come up for air eventually, but it needn’t be particularly soon, if Kadlawen has any say in the matter. 

Ateshai has fairly optimized lungs, and can indeed kiss for a very long time! He even gets slightly less gooey with practice and exposure!

Kadlawen doesn’t have optimized lungs per se, but he’s much less bothered by suffocation than the average person! 

They do still need to eventually detach, although Kadlawen sees no reason at all to stop doing that dance-massage thing with his hands, or to keep Ateshai’s hand from remaining precisely where it is.

”You are utterly and astonishingly amazing,” he says, breathily. 

Eeeeeeee! The return of the blush!

"You are too!"

Eee! Kadlawen is also blushing! 

This seems like an opportune moment to glance over at Runla.

"I am shocked you're putting up with my idiot of a brother," she informs him. She's fulfilling her duty as a chaperon by keeping a thorough if lazy eye on them.

“I’m shocked that your gorgeous, talented, kind, intelligent, motivated, and generally wonderful brother is putting up with me,” he replies.

Oh wow looks like that blush can intensify even more! (Runla snorts).

Gosh. He’s never really been the blush-er, rather than the blush-ee, this is kind of neat. His left hand drifts away from Ateshai’s back, and starts delicately tracing out the contours of his chest and abdomen.

They can probably maintain a bit of comfortable, moderately snuggly silence for a bit, and then: further kissing? Possibly involving additional tongue? 

Further kissing and tongue is a go!

Eeee! Kadlawen’s certainly been kissed before, but he’s never really kissed someone- it’s an interesting line to dawdle on the other side of, he certainly wouldn’t want to do it all the time, but it’s- nice? And it’s Ateshai, who is intensely attractive and generally great and! actually! likes him!, which makes up for quite a bit of oddity. And if this level of physical intimacy is rendered strange by a cultural barrier, he has genuinely no idea what any eventual sex might be like- the info sheet hadn’t mentioned whether Shifters even had roles, but it’s becoming kind of clear that they don’t have them in quite the same way, if so-

He decides to stop thinking about anything other than exclamation! points! and the fascinatingly innumerable number of ways through which he can continue being intensely pleasant to kiss, and succeeds. 

Ateshai does eventually need to breathe, even with thoroughly optimized lungs.

(He's slowly getting less hesitant with his hands, at least, and once he figures out "hands are a thing" he's slowly showing a dominant side).

Kadlawen is demonstratively enthusiastic about hand-based expressions of dominance! There are moderately indecent noises involved! That sort of thing is so much more in his comfort zone! And it’s also really attractive! Eee! 

He beams when they finally break off, looking just about as thoroughly delighted as Ateshai’s seen him.

... and, since he’s already made a habit of this whole ‘glancing at other things while temporarily not kissing’ thing, he has to admit that he’s pretty curious as to whether Ateshai’s enthusiasm is, well, visible.

Sort of? Maybe? (There wasn't enough adrenaline for Ateshai to get into it this quickly without his body having concretely learned what kisses lead to, but he's definitely registered the kisses as a Good Thing).

Kadlawen supposes that isn’t terribly surprising. He’s just going to continue being an attractive alien with magical sex powers and see what happens.

Shall they re-kiss? With moderately increased physical closeness, this time around?
