This was the first time I was invited to my girlfriend's house to play. I was also introduced to her younger sister, Hikari Ninomiya. Hikari Ninomiya was a very beautiful girl, especially her huge breasts that I couldn't take my eyes off of.

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 to play, Hikari Ninomiya used her deadly body to seduce me.

And the result was that 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!
