[CAWD-268] The first time I went to my girlfriend’s house, I was seduced by her slutty younger sister.

A secret sex movie of Rino Yuiki. This was the first time I was invited to my girlfriend’s house. I was also introduced to her younger sister, Rino-chan. Rino-chan is a very beautiful girl, especially her huge breasts that I couldn’t take my eyes off. It seemed like Rino-chan wasn’t wearing a bra, I could see her nipples faintly through her hoodie. And when my girlfriend went to wash the dishes, she pulled up her shirt to show off her beautiful breasts to me!!! And from then on, every time I came over, Rino-chan used her deadly body to seduce me. And as a result, I couldn’t resist this temptation and jumped into her extremely stimulating secret sex scene. We secretly had sex even though my girlfriend was still at home, even right next to me!
