You kneel and try to crawl across

“A true submissive proves devotion in every action and decision. Cross as you would follow your mistress.”

Not a particularly hard riddle for a man of your talents, you think. You watched enough femdom porn in your life to be aware that there in only one way for a submissive slave to follow his mistress.

That is of course on his knees, crawling behind her. That is the easy part. But how to prove your devotion in every action?

You get on your hands and knees, and from your lower position you notice that on a few tiles of the bridge there are barely noticeable outline of footprints, something which a particularly high-heeled shoe or boot would leave.

You know your task. You start crawling and plant a kiss on each of the tiles marked this way. Slowly, but surely you reach the end platform with the door.

The timer shows 10:23. A voice announces: “You proved your devotion. Remove all remaining clothes except your boxers and pass beyond the door.”

You comply, tossing your shoes, socks and pants away and opening the door without issue.
