They stop at the planet because Shiro wants to see some great crystal canyon. It’s beautiful, but no one told him about the local wildlife.

Keith comes running at the first shout and finds Shiro elbow deep.

It’s some squishy sort of creature, kind of like an octopus with all the tentacles, but it clearly lives on land.

And has wrapped itself tightly around Shiro’s arm.

“I can’t get it off!” Shiro shouts with panic. Keith raises his knife but... there’s no clear cut.

The thing writhes over Shiro’s foolishly barely arm, & Keith can’t risk it. He puts the knife away and reaches out with his hands.

It’s immediately a bad idea. The thing lengthens itself and wraps some of its tentacles around Keith’s arm.

That’s when things get really weird.

All of a sudden it’s like the world shifts. There’s a pulse of pleasure, a whirring of fear, neither of them belong to Keith.

“What—“ shiro says, reaching for Keith to try and pry them off. Instead the tentacles lengthen, twining up to Keith’s shoulder.

“Knife!” Shiro demands, and then when Keith’s too dazed to follow that, shiro tries to get it himself out of Keith’s waistband.

Except the tentacles follow, slithering across Keith’s chest and wrapping around the knife. Keith feels himself sway with how they spread the

haze through him. He’s being drugged, he knows he is, but he finds it hard to care.

He watches idly as the tentacles follow Shiro’s hands around, defying everything he tries. Keith looks at the ones on Shiro’s arm and wonders why they aren’t moving.

As if to answer, the ends twitch. Keith blinks and thinks of them against Shiro’s neck, caressing as nicely as the ones on his neck are.

Shiro makes a sound when they do. “Keith! Keith, fuck!”

“S’okay,” Keith slurs. He’s feeling drunker by the moment, but it’s a pleasant kind. Floaty and warm. “Nice,” he says.

He shows the man this by ordering the tentacles down Shiro’s belly. Theyre in casual clothing,

so Keith knows he can feel it. He makes sure he keeps them soft and easy touches. He wants Shiro to follow his lead, as the ones on his own body are still frantic and thrashing.

Still Shiro keeps panicking. “Keith I need you to focus, it’s effecting you worse.”

Keith reaches and touches Shiro’s chest. It’s so huge and nice. He draws his fingertips across it, trailing tentacles that pet and tease.

In his head is a reverberation of the sensation, denied pleasure. Keith wishes Shiro would just feel it. It’s nice.

“Keith!”

Shiro groans then as first Keith’s finger and then the alien pass over his nipple. A strong sensation comes through the link then.

Keith wants more.

“Stars, Keith I cant— you’re not you—“

Keith hums, hands falling down to the hem of Shiro’s shirt. “Want,” he says plainly.

Shiro makes a stuck sound and tugs, almost bowling them both over. He curses.

“Jus’ g’ntle,” Keith says.

“Gentle he says,” shiro says. He looks peaky and flustered. Keith wants to lick him.

“Soft,” Keith adds. He brushes his fingers beneath Shiro’s shirt, the tentacles trailing. They look gorgeous against Shiro’s skin. They would look better—

And then Shiro gives in. It’s like a mental wall lowering, feelings and sensation rushing from his direction into

Keith’s head. Shiro’s afraid. Angry with himself. Uncertain. Guilty.

Aroused.

In love... with Keith. Oh.

Keith tries to send back his own. His brain is a drunken mess, but he still knows who he is. He still feels the same for Shiro.

Shiro looks awestruck.

“Is that... real?” He’s watching Keith like he can’t believe it, creature forgotten.

Keith trails his fingers at the edge of Shiro’s pants. He doesn’t understand the /shock, disbelief, uncertainty/ coming from Shiro. Keith’s beyond those things.

All he does is /want/.

He hums an affirmative. It’s all there, anything Shiro needs to know. Keith doesn’t care to discuss it. He feels calm and pleasant and he just wants more. Wants to be twined up in Shiro’s lap, stuffed full.

The tentacles help. The second Keith’s thoughts go that direction, they begin to pluck at Shiro’s clothing.

There’s some mild protest, but then Shiro thinks about Keith and sex and removing Keith’s shirt as well, and the tentacles on his body do so.

Before any time at all KEith has him on the ground, tentacles wrapped around Shiro’s thighs and wrists to keep him down. Keith has some ideas about riding him that he broadcasts clearly.

“Wait!” Shiro urges as Keith crawls over him. The man is blushed red, but between

his legs his cock is leaking and swollen. “We’re drugged. I don’t even know—“

Keith is tired of excuses when he can so clearly feel their twinned desires. In his head he wraps them tightly together and then bowls it into Shiro’s head.

Shiro cries out, arching against

his bonds, cock bobbing.

Keith doesn’t waste any more time. There’s some slickness from the creature, and Keith let’s it slide down between his legs and begin to open him up.

While he does this he directs the tentacles on Shiro to explore, teasing, touch. He plays Shiro’s

body as if it were his own, listening to the cues in their head for where and how to touch.

When he’s finally opened enough, Keith lowers himself slowly onto Shiro’s cock.

Shiro’s slipping down now to where Keith is at, so language doesn’t come to him anymore. Instead

Keith hears his filthy enjoyment in his head. How hot and tight he is. How much Shiro wants him, has always wanted him.

A hundred perverse and secret fantasies run through his head. Keith feels like fire, powerful and godlike. He begins to move.

He rides Shiro filthy and quick, directing the tentacles to support him, get the angle right.

Shiro has a thought and one of the tentacles slithers down to encircle Keith’s cock.

In retaliation Keith sends the slick down down beneath and to Shiro’s hole.

It’s a depraved spiral then. They feed each other directly, spinning fantasies each filthier than the last. Keith bounces on his lap and fucks Shiro with a tentacle. The tip of one pushes in beside Shiro’s cock, stretching keiths hole.

Their orgasm, when it comes, is like nothing else. They share it in mind and body, writhing against each other, feeling it all.

Keith cries out and spills thick across Shiro’s belly as Shiro grunts his pleasure inside him. They throb and whine and /feel./

They collapse beneath it, smothered and happy. It’s so complete neither of them even notice when the creature untwines itself with a mental “thanks for the meal” and slinks away.

Keith only notices when the clarity comes pouring back in. He turns to Shiro who’s looking at him

stupified and sex-drunk.

They both start to laugh, twining into each other, reaching for each other’s mouths for a too-long-awaited first kiss. It’s ridiculous and perfect.
