Trying to find a story...

It involved a couple returning home to find a package containing an incriminating video.

They are forced to submit to sexual servitude...he undergoes a lot of forced bi action while she enjoys lots of sexual adventures.

I seem to remember the point of it all was to liberate her while making him submissive. There was a scene where she sat on a sex-chair while she watched him getting deflowered


any ideas?
