The gag attachment was definitely challenging. You are correct that it added significantly to how restrictive the already heavy bondage was. My arms were encased in a leather sleeve behind my back that was tightly laced up and then tied off to another part of the bondage frame. However, I was not squating to much as you describe, I was close to pretty much standing up straight. MTO has a well deserved reputation in all things bondage. I think we played for 3 hours for that session and she expertly moved me through several very challenging bondage scenarios.
