Pulses Triggered by Sound-Part 1: Face-up Suspension and Metronome Rhythm

Mistress Ruiko suspends her sub face-up with rope and attaches clamps to his nipples that deliver electric pulses. These pulses are triggered by sound — any noise he makes sends a shock through his body. She sets a metronome ticking, and the pulses begin to match its steady rhythm, heightening his fear. Though he tries to stay silent, his moans inevitably escape. Toward the end, she intensifies the torment by attaching candles to the rope and taking the punishment even further.
