reads the other part, which is set before this so part 1, not part 2.but whatever.
Story starts, woman 5 years without a husband/sex engineers an encounter with her boss. gets paid for sex. apparently between the two parts she also engineers that he marries her.
Woman is aware of her daughter's live stream. she likely informs the husband and has him deal with it at a time when she is not home. to its logical conclusion. Not entirely sure why she'd set the man on her daughter but she definitely engineered everything up until that point. she's masturbating to it, so maybe their sex life needed a boost. keep things fresh.
