The slave has been kept in chastity for 12 years. It is finally let out after working for You and Your husband in complete chastity for 12 years. You want to see if "it" (its cock) even still works after all that time in chastity. So you command it to kneel before You as You sit on Your throne and tease it with Your long legs. (But mostly You just ignore it and mock it and play with Your phone while it literally stares up at You in WORSHIP and strokes its pathetic cock to Your beauty!)
You forget about the slave after telling it that it is not allowed to cum without Your permission. It has to keep stroking itself but NOT cum for what seems like FOREVER...just to see how long it can last staring at Your magnificent beauty!!
