Evaluating the Merchandise
Stella opened a door at the back of the pleasure-house and revealed a broom closet. Before Esmeralda could ask what they were doing there, Stella led the way inside.
"This way."
Esmeralda gingerly made her way between the brooms, mops, rags, buckets, brushes, and feather dusters until she made it to the far end of the room. There was another door there, past a bend that was invisible from the entrance. Beyond that door was a dark corridor. They walked through it, slowly and quietly, until Stella stopped.
"Here," she whispered.
She pointed at a crack in the wall through which certain sounds filtered through. Esmeralda looked through the crack and found a familiar scene of a pleasure-slave at work. Stella must have understood that Esmeralda would want to evaluate their job performance. Clever girl.
