Wrap her in string

How about you hand the robe back to her - what’s left of it anyway. You first take off her undergarments, carelessly throwing them over your shoulder while taking in the view of her incredible boobs. Once you finish admiring them, you take the cluster of unravelled string, and fling it over her, wrapping the string tightly around her body several times. Her hands are pressed against her waist, and her staff gets wedged in betwen her cleavage. Most importantly, the strings leave her breasts prominently poking outward.

Time starts again, and the diviner yelps, finding her entire body constricted.

“What trickery is this?! Untie me!”

She wriggles and struggles, accomplishing not much more than having her breasts jiggle between the strands.
