A curious solo explorer, eager to push boundaries, decides to experiment with electro-stimulation during a private massage session. Naked and vulnerable, he lies on the table, his stiff cock throbbing with anticipation. Using a handheld electrical device, he applies gentle shocks to his engorged penis, gasping at the unexpected sensations. As the current intensifies, his hand works the length of his shaft, milking pre-cum from the tip. The combination of manual stimulation and electric jolts drives him to the edge, his body tense, muscles clenching. With a final, powerful zap, he unleashes a torrent of semen, his orgasm pulsing through him like a current.
