LFS: Wife becomes slave for a month

[theonekaiser]

Looking for a story I can't seem to find now where a husband and wife want to move away from their town and start a new wife, but a guy who used to hit on her all the time is a super wealthy influential asshole whose dad owns the company the husband works for. He makes it difficult for them to sell their house and stuff and makes a deal that he will let them go and pay them but only if she becomes his sex slave for a month or something. He then tries to get her to fall in love with him. The whole thing is sent to the husband via videos. I think it ends with the asshole being threatened with a chainsaw haha.

Any help would be appreciated.
