I see. That is kind of disappointing to know, but I can understand the reasoning.
Still, I find that dom bottoming can be more humiliating to the top, especially since the top is generally the one that is thought of being in control. So the fact that the top and his dick simply became nothing more than a toy for the bottom to be used makes the domination and humiliation that much more poignant. Overall, great job on the game. I wish you the best.
