"You've been a good little slave," she purrs, unlocking the chastity device that's been tormenting him for weeks. His cock springs free, engorged and desperate. She takes him in her hand, his skin soft and sensitive from the prolonged denial. She teases him, bringing him to the brink, then backing off, making him whimper and plead.
