Mom catches Joey backdooring Laticia. She freaks out at both of them, especially Joey.
The next morning, she still won't discuss what happened with Joey. That was the end of the update.
It seems that Mom needs extra coaxing before Joey will earn her consent for any sex acts together.
One such trigger must be that Linda discovers her husband has been unfaithful for some time. Together with her friends' blessing (certainly Mrs. Kelly but also Mrs. Jackson) and her own inclinations, the endgame seems assured.
But all this, with the glorious Mrs. Gloria playing the bad-witch role, looks like it will take a good long while.
