You'll jerk off today for as long as I want you to. It will be a very special jerk off task for you, because you won't stop after you have cum, but will, instead, simply go on jerking off as hard as you can. When I tell you that you are allowed to cum I will look at the clock and you will continue to jerk off for your mistress and you won't stop for a while. For another minute, you will continue to work hard for me, you jerk off puppet!
