How Do You Handle Longer Face-Sitting Sessions?

There’s nothing better than being pinned down and completely smothered, but after a while, the lack of air gets intense. I’ve learned that positioning makes a big difference—if my partner leans slightly forward or shifts their weight just right, it lets me last longer without needing to tap out. Also, focusing on slow, controlled breathing through the nose instead of panicking helps a lot. But I’m curious, what’s the longest you’ve lasted under a good face-sitting session, and do you have any tricks for going even longer?
