headcanon that at the beginning of keith and shiro’s relationship shiro always wanted to turn the light off during sex bc he was ashamed/insecure of his scars. keith is supportive at first bc he’s dreamed so long of being w shiro that he doesn’t push it, but as time goes on and they become more and more comfortable w each other, sexually and romantically, keith gets increasingly frustrated that shiro doesn’t understand how gorgeous he is.
so they’re in bed one night and shiro reaches over to turn off the light, flush high on his cheeks, but keith presses his wrists down onto the bed and tells him to stay put. he strips shiro down, slow and with careful hands. shiro doesn’t argue, but he’s clearly uncomfortable and not even hard to boot; so embarrassed that even his thighs are shaking.
keith maps out his body, presses a kiss to every scar, every mark, every freckle, every divot. shiro screws his eyes shut, his breaths erratic and panicky. keith stops briefly, just long enough to reach forward, hold shiro’s face in his hands.
‘look at me,’ he whispers. shiro’s eyes flutter open, strikingly gray and shining with unshed tears, like a thunderstorm amongst a hurricane.
‘i’m not–’ shiro cuts himself off, inhaling a shaky breath. ‘i’m not what you expected, right?’
keith presses his lips to shiro’s forehead. ‘no,’ he murmurs, ‘you’re more beautiful than i ever could have imagined.’
shiro ends up crying so hard that they have to take a break. keith holds him, whispers sweet nothings in his ear, makes promises of reassurance. when shiro calms down, they make love with the light on for the first time ever, and when shiro comes, toes curling and mouth falling open in bliss, keith thinks, i’m the luckiest bastard in the world, and falls in love all over again.
