FF-006 - Singing sweetly and skillfully, Mizuya Mariko

I'm working hard using fellatio as a vocal training tool~ Mizuya Mariko, 21 years old/B83・W57・H86・T155. Mariko was a little late compared to everyone else, it was when she was 20 years old. That was it. She wants to become an opera singer and is currently taking intense lessons. She wants to be like Maria Callas. She is doing fellatio for opera vocal training. Opening and closing her mouth wide, and moving her tongue diligently, makes it very good training. Everyone praises her. So, fellatio is Mariko's specialty more than sex. Ah, I want to become a first-class opera singer soon. Please watch and support me.
