A lone figure, dressed in worn-out workwear, seeks solace in self-inflicted torment. Bound at the wrists, he meticulously attaches electrodes to his sensitive flesh, his breath hitching with anticipation. The first jolt sends a shiver down his spine, his nipples hardening as his cock twitches. He loses himself in the rhythm of pain and pleasure, his body writhing in his private bdsm haven, the only sound the faint hum of the estim machine and his ragged breaths.
