In his private sanctuary, he succumbs to the allure of electrostimulation. The device's tendrils caress his flesh, sending jolts of pleasure-pain through him. He writhes, his cock hardening, leaking pre-cum. The current intensifies, his body twitching as he fights the urge to touch himself. The room fills with the sound of his ragged breaths and the device's steady hum. As the sensation peaks, he loses control, his body convulsing as he cums hands-free, the room echoing with his cries of ecstasy.
