English: The male subject begins the video naked with a Tremble Stroker Open Ended vibrator on his flaccid penis. The vibrator controls are taped to his back so he will not be able to reach them once he is in bondage. He puts leather wrist cuffs on his wrists and then secures them to an armoire door with timer locks. The timer locks are set and you can hear them engage as they beep. The subject now cannot take off his cuffs or turn off the Tremble Stroker Open Ended vibrator that is pleasuring his penis. During the video you see his penis get more and more erect as the toy pleasures it. The subject comments to the camera that he cannot touch the vibrator nor adjust its speed. The subject announces that he is going to climax, after which he visibly ejaculates a large quantity of semen. Unfortunately for the subject the timer lock still has several minutes to go, so he must endure the vibrator stimulating his penis during post orgasm sensitivity. Finally he is able to release himself from the timer locks and turn off the Tremble Stroker Open Ended vibrator.
