Director Aida Yumeno's popular series "Ultimate Subjective JOI" is back and more powerful than ever! This time, the content is focused on CEI. CEI is a perverted play in which you are ordered to drink your own semen. Follow the orders of the dirty-talking slut, one corner per day, and complete the seven short corners. Save after you finish one, continue the next day, and do your best to avoid a game over. This is the start of a week in which you are looked down upon by a dirty-talking slut and trained into a super pervert who drinks the semen you squirt from your own penis.
