( they will stop, if keith ever says as much -- even shiro isn't confident enough to know whether it'd be sincere or not, whether keith calls it quits because he thinks he's imposing, or because he genuinely has lost interest in shiro. he wouldn't mind, were that the case. he doesn't believe himself as capable of deserving good things -- which, like memories, are always fleeting. he's so much older than keith anyway, eventually he'll realize that he wants something else, and shiro will be stuck saying i told you so to himself.

he allows keith the time needed to get used to it, holding him solidly with one fleshy hand and one metal one, both pressed on the toned muscles of his sides. he follows orders nicely, and shiro rewards him on point, pressing his real hand against the front of his jeans and giving his cock and good squeeze, flirting around the button and just barely teasing it open, slipping inside to palm him through his underwear. )

Yeah, ( he hums, a rumble in his chest, bullying keith's face downwards so he can press a warm kiss on his mouth, sucking on his lower lip. ) good girl, already hard. You fit in my palm just perfect.

( he turns to kiss at his ear, his voice husky and low while he speaks directly in the shell of it. )

Why don't you help Daddy out of his pants and suck on him, a little? On your knees.
