[Women's lovey-dovey anal torture work] Lovey-dovey couple Waka and Riku. One day, Waka hears from her friend that "a man who feels like anal is cute" and becomes interested in a man's anal. She is not interested in other men, so she asks Riku to develop an anus. Originally, Riku said normal, anal, etc., but the development was gradually successful, and finally a Ketsumanko dedicated to Waka, which is only good in the buttocks, is completed!
