I once saw something similar at a spanking shoot. The primary top was expected to spank about 6 gals in a row. Late in the scene she stopped mid-spank & asked to rest her arm. The director said "well why don't you just finish the scene, & then rest". He argued with her! I really felt felt for her.

I'm so worn out today I feel physically sick.

Thanks for sharing this stuff. We consumer perverts have no idea what goes on behind the camera.
