Sanji being tied up was a treat. The wiggly cook was hard to pin down, and he didn’t particularly like being restrained when they were on the high seas, just in case of an attack, but hotels?

The positions for only them to see and enjoy. Really, the cook of the Strawhat pirates was easily one of their most prized possessions.
