In the dimly lit workshop, a lonely technician finds solace in his own touch. 'Tecnico-Da-Oi' captures the raw, intimate moment as he unzips, revealing his throbbing cock. He strokes it hungrily, his fist gliding up and down the veined shaft, precum beading at the tip. His breath hitches as he picks up the pace, his other hand cupping his balls, teasing the sensitive skin. The room fills with the wet sounds of his self-pleasure, his grunts echoing as he chases his release.
