"This second itinerary is a testament to the successful response we received from Desire Venice Cruise and marks the beginning of several other experiences we aspire to create for our guests."
As well as the private playrooms and nude-friendly atmosphere, guests will be able to enjoy "provocative theme nights, spicy daytime events and couples' workshops letting passengers get in touch with their romantic, sensual side".
There will be a playroom, jacuzzi lounge, and the opportunity to "mix with like-minded, socially sophisticated, experienced couples in a safe and like-minded atmosphere to live out their fantasies", Original Group said.
Dining options on board will range from "casually playful to erotically elegant".
Desire's first journey through the Adriatic Sea, dubbed "Venice Foreplay", is already on sale and departs from the Italian city in September.
Nude cruises aren't everyone's cup of tea, but for those who would happily go the full monty on their holiday, there are plenty available.
But there are a few rules passengers should know about: on the Desire cruise, you can't be naked in restaurants, and photography in the ship's public areas is strictly banned.
Just in case you were wondering.
