Finally, the voluptuous slut, Chitose Yuki, appears in the ultimate subjective JOI series! [What is JOI...?] It is a video that instructs and commands the viewer on the speed and frequency of masturbation, the time until ejaculation, and whether or not ejaculation is allowed. You will be instructed to jerk off in a world where you are alone with a dirty-talking slut, and you must obey the orders and complete what you are told. Experience overwhelming pleasure and agony as you are educated in perversion with a teasing countdown that will keep the M-man alive and dead!!
