An unusual masterpiece from DORA MAX! "Hey... Which one do you like, Taka?" Childhood friends and twin sisters, Mami and Yumi. I've been in love with these twin sisters for a long time... Our story accelerated when I was alone with Yumi yesterday! The two with the same face have completely opposite personalities and sex play, with a huge gap! Yumi, who is good at aggressive sex like a little devil. Mami, who shows devoted sex with emotion. What is the outcome of the triangular relationship unfolding under one roof?
