Supervising The 69 With A Whip
Quite honestly I don’t see how Our Mistress Of The Sixty-Nine here could hope to swing that whip without the man on the job being at risk of losing an eye. Perhaps the martinet is merely the badge of her supervisory office, and her moral authority is sufficient to carry everyone through the task?

Best use is directly on the male buttocks during missionary position or on female buttocks in female superior, causing her to clench and grind harder and faster, or causing him to pulse harder and faster.
Here, in the 69 position, you DONT want the chaperone to swing lest the spanned bite down in pain. So the chaperone is instead dangling the martinet tails to caress the upward buttocks, inducing anticipatory bucking and grinding by the woman and more fun for everyone involved or watching.
