In the quiet of his room, a man engages in a solo struggle against his automatic masturbator. With a throbbing, pulsing cock between his legs, he fights the urge to cum, his moans echoing through the room. The big dick toy, a test for his self-control, provides intense friction and a relentless rhythm. He grips the machine, his knuckles turning white, as he tries to hold out, his body twitching with each wave of pleasure. In the end, he succeeds, his cock glistening and hard, yet untouched by release.
