The issue that confronts Suki and John is: Neither if them want a marriage certificate, but they want a committed relationship, which they have.
Sunshine discovers this and forces Suki to marry her, then forces Suki to have an affair on camera with Suki's best friend and new lover of Sunshine.
When John finally gets back from his week long trip, Sunshine drugs and otherwise coerces him into impregnating her, Suki and Trish.
John is forced to provide massive child support to Trish and Sunshine, although they sell their "strong natural gened children" and Sunshine sells Suki's baby too.
Suki is forced, by the courts, to pay Sunshine spousal support.
