Just a thought on a good progression for a beta husband that think's he's straight:
1. Achieved just by bitchiness most of the time, reduced to being allowed to fuck her once a month and, apparently unrelated, frequently bringing up masturbation and how it is completely unacceptable and even one time, she'll divorce him
2. Explicitly told the rule is once per month and NO MASTURBATION. But still allowed to fuck.
3. Reduced to handjobs once per month, explicitly told no more fucking except MAYBE on your birthday or Christmas
4. Required to have buttplug inserted for the handjobs
5. Dildofucked by hand for the handjobs
6. Strapon fucked with reacharound if necessary
7. Wean off of the reacharound and if he doesnt' cum then just too bad, better luck next month
8. Reveal she has a stud as of course he has NOT been satisfying her, and now must have his cock in mouth or cannot cum from the strapon
9. May only come with cock in ass
10. Reveals she has a BFF who also has a cuck hubby and from now on, they're just going to have to queer off together as she's not going to have any kind of sex with a faggot.
