Ebony's body glistens under harsh lights as she's securely bound in intricate rope work, her dark skin contrasting against the white fibers. She's gagged, her eyes watering as she looks up at her dominant, awaiting instruction. The room echoes with the sounds of her muffled moans and the creaking of the ropes as she struggles slightly. Her tight asshole, lubed and ready, gapes as she inserts a thick, black dildo, working it in and out, stretching herself for the next step of her training.
