As cute as it was to watch JARVIS be so seriously intent on getting cleaned up, Sam took the sponge and urged JARVIS into putting his back toward Sam so one could properly soap and rinse the other's back.

"Pretty much. It's not really all that exciting, though I tend to be a 'showers' kind of guy."

Sam honestly couldn't remember the last time he did an actual bath by himself. And seeing as how you were created by Tony Stark, you've probably seen enough to write your own version of the Kama Sutra. In Binary.

"...You know usually when it's two people in a bath together, there's a lot more than just getting clean going on."

And since Sam doesn't want to push too much, He'just going with lingering fingers on spine, upper arm. shoulder.
