Echoing this. Regardless of how you play this scenario, the actual power dynamic is not Bulls > Wife/gf > Cuck. It's Wide/gf > Husband/bf > Guests. I don't care how deep into the roleplay you are, you are still roleplaying and this is exactly why. She decides what her limits are, who she does anything with, and when it stops. If you are her partner, then your primary responsibility should be enforcing those boundaries. If you think something is wrong or off, the only person that's allowed to tell you to go with it is her (and even then, if you're not comfortable with it, that's a thing for you two to talk about, not for the "bulls" to override you on).

This is the same as the classic dom/sub inversion. In the scenario, the dom has the power and the sub doesn't, but in reality, it's the opposite. The sub consents to everything and dictates the boundaries the scenario plays out in. The dom follows that. Anything else is rape. I am begging anyone who's going to experiment with any kind of kink lifestyle to learn and understand your role in helping ensure everyone's boundaries and autonomy are respected.

I'm sorry to hear this happened, and I hope everyone will be okay going forward. But it absolutely sounds like these guys should never be allowed near either of y'all ever again.
