The section at the beginning you comment on is merely a micro-recap of the first chapter. If you take the time to check it out, you will see that the gags do come off before the licking. No laws of physics were violated in this story.
When you wrote that the girls were gagged separately and forced to lick each other in the 69 position. Hard to lick anyone or anything if you're gagged. I figured the rest of the story would be similarly bad. Did you even bother to proof read this garbage?
