ABC of cuckoldry
H: Humiliation
Humiliation is good for you. It reminds you of your place. Continuing to harbour false hope that maybe one day your hothusband/hotwife might regain interest in sex with you only makes it harder for you to accept your true and rightful place in your relationship. Such delusions can make being a cuck from what should be a pleasurable experience -- what greater joy than knowing that they get the satisfaction that they deserve because of your acceptance of being a cuck? -- into a torturous struggle.
Of course, at first achieving that acceptance might be difficult. That's why humiliation is important. It's one thing to think that you should be able to make love to and pleasure your partner; it's quite another to think so when your partner's bull compares his beautiful big cock to your pathetic little locked nub. Which one do you think makes your partner's toes curl and their eyes roll backward? Blushing, in that moment, you cannot but admit that your partner's bull is just superior and you find yourself compelled to praise him and beg him to help your hothusband/hotwife achieve the sexual ecstasy that you never could offer.
Besides, you get off on being humiliated like this, don't you? There's no point in denying it. They both see your little caged nub straining. The harder they laugh at you, the more you strain.
