Having each victim lower her panties is great. Flogging each girl and the sound of the flogging is excellent, but I don't think the lashes were laid on hard enough. No real marks to show for all that effort.
Great to see this one again, saw it some years ago and love the over the barrel position. Have to agree with Jim and rattanman that the cane would have been a better implement.
Nice video but a slight shame the white shirted girl did not flog the first two girls - I suspect they got 10 licks each, shown from different camera angles, but the third girl got at least 15. In part 2 they get 20 licks each (10 from each girl doing the flogging).
