How long do the visits come nightly to Juvenal in "Juvenal Nyx"? What is he left with when his "creator" leaves him?

For four days, Julia drinks from Juvenal's arms, legs and stomach while he lies in ecstasy. The next day, the chains are gone and so is Julia. A note left tells him that he is now hers and one day they will be together again. Meanwhile, the room is his to use.
