I Just wonder is she used it (the whip) also in the first pussy round
In the first pussy round they used the strap only. I think even Tatjana was touched by the cuteness and nice submissive personality of Cynthia until the point when Cynthia suggested them to switch places. Then they realized they treated her too gently, and for the third round Tatjana equipped herself with the feared device...
I got some feedback assuming the whip was used in round two based on some marks.
Please note that the white circle shows a linear mark which is a result of an imperfectly executed strap stroke, when accidentally mostly only the side of the strap hits the target. That is indeed similarly but differently painful and generally speaking should be avoided.
The red circle shows another very unlucky accident, for which Amanda apologized later. She accidentally hit too close, and a sharp part of the handle (a protruding screw) - scratched poor Cynthia's thigh... (click the picture for higher resolution)
In the third round you will see enough marks and some unfortunate bleeding caused by the single tail.
