Bearing in mind that the Japanese clean themselves before getting in communal baths (and think the Western idea of a bath where you sit in your own dirt is filthy) I would suggest that only chocolate on the bodies is licked off.
It still looks like my idea of hell, personally.
Get a
chocolate massage bar from Lush - much more personal. Just don't send it cheekily through the post to your amour's workplace, only to have the postroom leave it next to a radiator. Ahem.
