Exotic damsel Ekho Kumori is being held captive in her lacy black lingerie, stockings and garters. She's gagged with microfoam tape wrapped all the way around her head, and she's tied to the headboard in a lotus position -- with a powerful vibrator roped into place. Her mysterious captor turns on the vibrator, and soon the helpless beauty succumbs to relentless hum with a series of unstoppable bondage orgasms. Once she's exhausted, will the villain finally set her free?
