There 20 Bath
Sea water made Luffy weak and easier to manage. When Sanji forced him into the bath, his Captain didn't fight back and make a mess of Sanji's nice pants. The only water they had to use for baths was sea water and that was Luffy's one weakness.
Sitting in the medium-sized tub with Luffy in between his legs, pressed back to chest, was the best thing about baths. Luffy was lethargic most of the time, but Sanji enjoyed sitting there with the teen's wet head of hair on his shoulder. It was so easy to relax and get lost in the sound of Luffy's gentle breaths while the cook smoked a cigarette.
Of course it never lasted that long because one of the crew - Zoro, that damned idiot - would come barging in demanding food or wondering why bathing Luffy "took so fucking long".
After a well placed kick and a few minutes to dress, he was back in the chaotic world and silently wishing for his peace back in the bathroom with Luffy and the tub.
