Bound at the wrists and ankles, a submissive slave awaits their dominant's touch. The Mistress teases, running a gloved hand over the slave's naked body, tracing the curves and valleys. She lubes up, fingers first, then a thick dildo, stretching the slave's hole. Finally, her fist disappears into the slave's wet, eager cunt. The slave squirms and moans, the Mistress' fist pumping in and out, bringing them closer to release. The slave's body tenses, and with a guttural cry, they squirt, coating the Mistress' arm in their juices.
