Chapter Text

Keith couldn’t believe he was doing this.

He was doing this.

Breathe in. Hold it. Patience yields focus. Breathe out. As if you were blowing on a candle you never meant to put out. Keith doubted Shiro would approve of him using the techniques their PTSD seminar had ingrained into the paladins for this depravity, but what Shiro didn’t know couldn’t hurt him.

Keith submitted his picture and a quick summary into Grommr.

Stuff me and round out my abs. Night after night.
Can’t host. Discrete a must.
Humanoids only.
Bonus: slender pool boys

 

 

Being the leader of the defenders of the universe earned him no privacy, and if word of this kink of his got out, he’d be mortified.

Keith couldn’t live out his whole life without experiencing it either.

The picture had been taken from collarbone down. Lean muscle bulged out further with gains of the past few years. Perfect hard pecs. Perfect eight pack abs. A barely-there black trail of hair leading down to red boxers that were so tight they would no doubt pinch the moment he gained an ounce.

Keith gripped at his cock as he sprawled out on his bed aboard the personal ship he used to distribute supplies. That and it helped him distribute his body throughout the galaxy. He was no stranger to one night stands and hookups, but his gaining kink - that would require seeing someone repeatedly.

He figured he’d gain a few pounds and then call it off, losing the weight in time to make any real public appearances. Sure all his fantasies had him gaining more than that, but the embarrassment won over.

His inner turmoil was cut short as his messages inbox overflowed. A few seconds in and he’d already disabled sounds for the app.

Soon enough he began blocking people.

One was too old.

Another couldn’t spell.

This third man didn’t want any alien refugees on Earth. Hard pass. Keith wasn’t into racist assholes. He needed to plow an actual asshole attached to someone decent. Someone who exemplified compassion outside of kink play.

Maybe he was asking too much from a fetish matchmaking service.

He switched over to check his taps list, ignoring the repeated buzzes from a steady stream of new messages.

“Oh.”

Dazed violet eyes scanned over the expanse of skin. Caramel. Flawless. It glowed. Long limbs sprawled out on a beach. Earthen swim trunks tugged down low over tantalizing hip bones and a V-cut that could slice. No face, but the description made his breath hitch.

 

 

AlteanTwink4Chub
Blue eyes. Chubs are welcome to bounce on my eight inches -
or I can stretch my flexible legs all around those thick sides of yours as I ride you ;)

 

 

 

His heart stopped and then started back up in a probably unhealthy rapid pace as Keith swallowed the drool pooling in his mouth and smashed the messaging icon with more force than was necessary. He nearly dropped the Altean tablet.

 

VersFeedeeLFrn >What’s your location? I’m mobile, but can’t host. I’ll get as big as you want me

 

Did he really mean that last bit? Probably not. It wasn’t that his fantasies didn’t go there, but he didn’t want to deal with being publicly scrutinized. Still, a Grommr stranger didn’t need to know that. He would at least indulge the man in getting those initial pounds on him. Even that was stirring his interest.

Only a few ticks later did the message come through.

 

AlteanTwink4Chub >Oh yeah? Nice abs like yours all ruined and bloated? I’ll make it worth your while and then some ;) I aim to please. Gotta keep you happy and blissed out if I’m gonna make you outgrow everything you wear.
I’m in sector 875-K. Free whenever for you, babe

 

Quiznack he’s good. Damn good at words.

Keith took a moment to scramble for words of his own. Forget flirting. He needed action. Right now.

 

VersFeedeeLFrn >I can be there in 30 dobashes. Address?

 

AlteanTwink4Chub >Needy, aren’t you? Central Altea Hotel. The penthouse.

 

 

Some wealthy Altean then. That wasn’t especially necessary, but he did enjoy finer foods. 

Keith ran his fingers through his hair, expecting to meet his usual unruly tangles. Right. The red paladin had pouted miserably when he cut his locks earlier, buzzing the sides and back and pulling the front forward in a messy array.

Anything to buy anonymity, and Lance did go on and on about his recognizable mullet despite Keith growing it out into a ponytail. If oblivious Lance of all people could also pick that ponytail out at night in the dim light, so could the paparazzi. Paparazzi gifted with alien eyes capable of zooming in from blocks away. His hair had to go.

Snatching a glowing blue earring which dimmed into a dull black as he inserted it into his left ear, Keith willed himself not to break into a sprint running toward the pilot’s chair.

If only his ass would spread to touch the sides.

Calm down, Kogane.
