[ An easy grin still spread across his face, Sanji has to choke back a laugh at the confusion in Luffy's voice at Nami's playful teasing. Leave it to their Captain to not understand what kind of show she means. For a moment, he gives an amused hum, shivering a little as he feels the intensity of Zoro's gaze observing every little thing he does, watching as his hand ventures lower, applying a fine layer of lather dangerously low on Luffy's belly.

This all feels easy and familiar, even if they're once again starting to explore somewhat uncharted ground– but seeing the way Luffy leans back, trusting Zoro to hold him steady, brings forth that familiar warmth of fondness that's blossoming in his chest. So maybe it's not so different after all.

Grinning at both other men, he takes a half step backwards, head turning part way around as he extends a hand towards Nami. ]

Hey, beautiful? [ His grin widens as he calls out to her, fingers gently grabbing her hand and giving it a soft tug even as he's gently sudsing up the top of a thigh. ] Luffy doesn't know what you mean. How about we give him a little show of our own, yeah? You know, so he understands better.
