He'll make sure to make short work out of whatever mess there is back here - and there certainly wasn't nearly as much to contend with as there had been with their hair. Even if it isn't as exciting as being face-to-face and everything that entailed, but maybe those soapy hands working at his shoulders and back will be worth it.

And, maybe, Shinji won't be as quick as possible about it, now that he's got his hands working at Kai's back. Maybe he can take just a little extra time to rub the muscles in the other's shoulders a bit, wanting to ease away any tension they might be holding. And would it really be so bad if he lingered for a few more moments after that, trailing his hands down Kai's back and around to his waist, even if it doesn't result in any meaningful scrubbing?

For Shinji's part, it's worth sacrificing a little bit of potential smooching time to just kind of... admire the other boy. How nice, truly.
