The angst has to still sting for your cuck. Would it be as fun if he got so accustomed to seeing another man take you that he seemed ambivalent? I would think the real challenge over time would be keeping your cuck from being "broken". There has to two parts to this, one being your sexual satisfaction and, two being you giving him attention in a way that keeps him wanting to please you. Otherwise, it seems destined for failure.
I love watching how your relationship has evolved through your videos. Once just some kinky anal play with you occasionally being his sub but not anymore. Now he is a complete sub, you have a new man to satisfy you and all he is going to do is serve. This video just confirms what was shown 3 months ago in your last vids that he is the bitch in your relationship now, taking real cock and watching you get fucked by and service the same one.
