Finding a book.

[Rixx]

Honestly, at this point I'm starting to think this book is non-existent and i conjured it up in my sleep. It was years ago so everything is a bit vague.
The book I'm looking for is an erotica, like top tier steamy. Three men are chosen to help a Goddess free her twelve sisters or daughters, each daughter/sister is under some spell and the way to free them is making sure they reach their O or maybe some other condition. The men walk into this tower and its like different rooms with different women who have different powers, they need to go through each women in order to move to the next [i suspect they get something out of it, i cannot remember.] One man has an L shaped penis, another man is carrying around a talking sword named Bash and the last man is an ex-war lord. This is all I remember. Please help.
