Now, for this, I want you in a classic anal position: head down, ass up. This will help open your asshole. You can see mine nice and wide. Try to arrange so you don't need to go back and forth from this position to kneeling to be able to see the instructions or reapply lube.
Once you're in this position, and have arranged yourself so you can easily see the screen (or can shift to be able to see it), continue.
