It's very common for cuckolds to try to take back control just after they consented to being cucked, when they realize what is happening, because they are jealous. This is why I believe the only men who can be cuckolds successfully without regretting it are those who are truly submissive. For dominant men who want to bring another man in bed, it's best to just do swinging instead or being the one who controls the cuckolding.
And it is best to communicate each other's desires and limits instead of just trying to dominate the other person without their consent. Relationships that involve cuckolding without consent tend to either end or go back to how they were before the cuckolding. It is extremely important that your partner trusts you, otherwise this whole thing will fall apart eventually. It is extremely important to separate porn and fantasies from reality because reality is never the same most of the time.
Also, bulls should also respect the couple's consent and desires, unless the couple gets off on being pushed past their limits. So what I'm trying to say is that there are many ways to go about doing this.
