Story locating help required

I'm sure I remember getting halfway through a story about a couple who are blackmailed into surrendering the man into bondage. The chap has to endure all sorts of degradation whilst the women is treated like a Goddess and eventually she has to review tapes of his performance & decide whether to leave her husband to endure more *ahem* training or release him from his plight (while he looks on helplessly).

If it sounds familar I'd be grateful if you could point me towards it as I can't seem to find it via the search.

:span: :bondage:

Thanks for your time.
