This is the first time I've been 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 make me unable to take my eyes off her. It seemed like Rino-chan wasn't wearing a bra, I could see her nipples vaguely exposed through her hoodie. And when my girlfriend went to wash the dishes, she immediately pulled up her shirt, showing off her beautiful breasts in front of my eyes!!! And from then on, every time I came to visit, 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 made love even though our girlfriend was still at home, even right nearby!
