What if King kaneki had an itch on his lower back he couldn't reach so Touka scratches it for him. She accidently rubs the kakuhou area and he lets out an accidental moan (since the kakuhou is an erogenous area) and there's an awkward sexual tension in the air. (She's never seen the scary king kaneki look so red in his life hehehehehee)
ahhh that’s so cute! /// maybe Kaneki doesn’t have any idea of how that part of him would feel so when he asks her if she can scratch it for him all the blood goes up into her face and she thinks, oh fuck, oh fuck, this is it, this is the actual moment, he’s finally asking me to do that with him.
when her nails scratch lightly down his back, he claps his hands to his mouth, TOTALLY HORRIFIED by the noise he made. he realizes in an instant what she must have thought, and when she sees his violently blushing face she realizes that he had no idea what he was asking until just now, and she sighs and stops herself from banging her head against a wall.
this also made me think that it would be fun if Touka had to take care of a sick King Kaneki~
