No judgments here - I have a lot of kinks. But I also have rejection issues, whether I'm the one being rejected or the one doing it. And cucking feels too close to rejection.
It's been years, but I used to sometimes hire two tops at once. Even if I felt like one was doing better than the other, I tried very hard to make them feel equal appreciated. And usually in the trying, they both ended up being well-received, so to speak.
All that said, there is a certain hotness to what unfolded. Just not for me.
PS - I would like to add that I have had scenarios where both tops understood that one of the tops would be more or less taking the lead. But they both knew that going in and were both fine with it and no one was cucked. It was more than one was Batman and one was Robin, so to speak.
