I do share your kink, but when it comes to finding a video about a wife witnessing her lover belting the cuckold, I'm at a complete loss myself. Most unfortunately ...
Not really a major part of the cuckolding scene. The lover is stomping all over the cuckold's masculinity by satisfying his wife's sexual needs. The wife is stomping all over her hubby's masculinity by replacing him with a real man in her bed. There is no point in wasting the energy. The man has cheerfully provided you with the most pleasurable thing that he has! What kind of man rewards such a guy with a belting? Hubby won't be strutting around after witnessing his wife receive a solid fuck from a man far more capable of delivering the male. Wife will bitch slap hubby and keep him well trimmed with cutting remarks and simpering as she feels it is needed.
Gay videos may possibly be one source of the heavy kink that you seek.
..............PSEUDO PERSON...YMMV!
