He assists her.

"That is an excellent idea." The Whipmaster said. He walked over to a **** scrubbing the floor on all fours. Aurélie watched as he ordered the **** to stand and walk to the closest wall. The **** faced the wall placing her palms against it and spread her legs wide. The Whipmaster brushed the woman's brown hair over her shoulder baring her back for Aurélie's aim.

"Here's a perfect target for you to practice on." He said returning to Aurélie's side.

Aurélie's gaze walked up the soft slender legs of the woman to her hips. This **** was dressed in a dirty loin cloth. A simple string held up two rags that draped over her back hips and front. Above the rags was a lower back tattoo that simply said "Use me". Looking further up the woman's back Aurélie could see bruises and welts from recent whippings.

The Whipmaster snapped Aurélie's attention back to her task as he cracked a whip against the slaves back eliciting a sharp cry from the woman. "Now practice on her while I attend to the galley rows. She will not move from that position as you whip her but I want to hear her screams or you'll end up beside her feeling my lash." He said sternly to Aurélie.
