Untie her

The noblemen are out of shape and lumbering, having grown fat from the labor of others on their estates in the countryside, probably. Their waddling isn't going to catch up to this slender young lady running for her life, but now she's constrained: her hands bound, feet constricted, on her knees with her ass hanging out.

You're feeling generous, and maybe a little bit eager to deliver some more justice personally, so you decide to move in to provide her with some help. You untie the laces you bound her hands with - an expert knot, if you do say so yourself - and put her laces back in her vest. That's for a later time. You move then your hands further down, running them along her exposed butt, and give her a pinch for good measure. It's such an inviting scene after all.

You walk back to from where you were watching, allowing yourself to ease back into the normal pace of time.

The thief immediately notices her hands are free. Not wasting the opportunity given to her she immediately hoists her pants and silk underwear back up and makes a run for it.

After a short distance of the nobles makes a dismissive gesture with his hand, indicating he doesn't think it's worth pursuing her, and begins collecting the scattered coins instead. The other, already out of breath, seems to agree. You snatch a couple of the coins yourself - you are a master thief after all, and set out to find your little refugee from justice, to provide some additional justice.
