#Sheith cute fluff cw alien biology?

The more time keith spends with the Blades, the more Galra he becomes.

When he sprouts the CUTEST little lynx tail, Shiro's eyes get HUGE.

He wants to touch it, but while Keith's body is changing, the new

bones and flesh are tender and sore.

Still, every time he sees it, the little thing swaying slowly as Keith gets used to it, Shiro can't help it.

So he begs Keith to let him try, that he will be so gentle and careful.

Keith bites his lip, unsure, but agrees. Shiro is always

gentle.

There's a sore spot right at the base, rubbed raw from Keith's pants. Shiro growls that Keith shouldn't have to wear clothes at all.

The half galran man rolls his eyes. He concurs tho.

Shiro asks Keith to turn around and Present Ass!

Keith spins around on the bed and

puts his ass in the air and his head down on a pillow, looking back over his shoulder at his husband with both utter love and trepidation.

Shiro's fingers touch lightly at the sore spot and Keith hisses through his teeth.

There's a salve in Keith's drawer he's supposed to use

but he hasn't had the courage yet.

Shiro clucks and fetches it, gently rubbing some of it into the base of Keith's tail.

That makes Keith's pointed ears go sideways as he finds relief for the first time.

He sighs at the coolness and Shiro wipes off his fingers only to stroke

up the shortfurred underside of his lovely husband's tail.

Keith makes the funniest mrrrrip! sound and Shiro grins as Keith blushes.

Shiro keeps stroking up and down the underside of Keith's tail, patently avoiding the oh so tempting hole not centimeters away.

that tail starts

flexing and twitching so Shiro holds it ever so lightly and croons to his boy how gorgeous he is with his little tail.

Keith hums and crrroooos, his eyes going sleepily half lidded while his husband appreciates the new and interesting ways his body has changed.

When he feels

Shiro grip his butt only to rub over his cheeks then up his back, massaging over muscles wound tight, feeling his purring love relax under his calloused hands.

Keith loves the way his husband is so much larger than him, because he covers Keith and whispers filthy things in his

velvety pointed ears about what he's absolutely going to do to Keith and his tail once that sore is healed.

It sends shivers down Keith's spine that make his tail fur puff up!

Shiro sits back, marvels, and laughs at the way Keith grumbles and mutters about how now he can't hide

any of his emotions from his lover and thats gunna make it hard at christmas!

(lol have some tail kink kinda sorta?? ok im going to bed now, i gotta work tomorrow)
