Any Suggestions? (dominated couple in chastity)

[swfdressed4good2]

Any suggestions for stories about dominated couples (either submissive/enslaved/kidnapped) who are kept in chastity and forced to observe their significant other being used/humiliated/etc? Ideally straight couples, married especially.
