BDSM scenes are hard for a cuckold to watch. At first, this may look like the Dom is abusing his wife, but it is actually a consensually negotiated exchange of power.
Hitting a wife’s pussy with a crop like this is something that she actually wants, and it’s hard for a cuckold to come to terms with that, because he’s been trained to believe that women want a lover who is nice.
This is not always the case. Many women identify as submissive, sexually, although this has no bearing on their outward functioning in the world. Since their beta husbands are not Dominant, these women end up sleepwalking through a vanilla sexual relationship, never being able to express what they want, as their husbands won’t understand.
Introducing a Dominant Alpha Bull into your marriage is the best way for your wife to explore herself sexually, in a safe and loving environment.
