[ shiro is strong. keith's known that for a long time now. after all, just how many people have the grit and balls needed to defy an entire military chain of command and go to space with a muscle wasting illness? that defiance is something keith admires intensely about his best friend, but right now that strength is manifesting in a way keith wholly dislikes, shiro is strong physically, too -- the reminder had been burned into his face not too long ago, and though the galra arm isn't lighting up or anything, a part of keith that's more alert is starting to panic.

again, it doesn't quite manifest in a way that makes sense. instead, the aphro warps the fear into something else -- fear that something bad could happen if keith fails to calm shiro down with sex. he cries out sharply when shiro finally prises his legs apart, then flinches at the metallic scrape of the chain keeping his hands overhead. teeth grit, he attempts to twist and lets out a pained hiss when it strains his shoulders unnaturally. ]

How - how is this caring about me? [ he pants heavily, ignoring the burn of his shoulder. ] That doesn't make sense!

[ but then it sort of does? keith's next painful attempt to sit up is cut short by shiro's hands pressing him back down on the cot, weight fully bearing down on his body between the v of his legs. he gasps as air gets knocked out of him, head thrown back on an uncomfortable pillow.. where he'd been snarling seconds ago, keith groans the next, calves winding tight around shiro's ass as he grinds mindless in his enthusiasm. in lieu of having hands, he arches up to snag the shell of shiro's ear in his teeth. ]

C'mon, Shiro. I know you want it. I can feel your cock riding hard up against my ass. You want it, I want it. Fuck me, fill me -- fuck, c'mon, give it to me.
