Bound and helpless, the slave's small cock twitches in anticipation of his mistress's touch. She smirks, "Let's see what you've got." She strokes his shaft, her long nails scraping gently, making him gasp. His cock struggles to harden, but her cruel words keep it limp. "Useless," she hisses, "You'll learn to please me, one way or another." She straddles him, rubbing her wet pussy on his pathetic erection, taunting him with what he can't have.
