Her Beloved Younger Step-brother Got A Girlfriend... I'm Jealous And Want It So That He Can't Have Sex With His Girlfriend, So Every Day I Empty All The Cum From His Balls. Sumire Kuramoto

My big brother, whom I love most in the world, got a girlfriend. I thought we would always be together as brother and sister from now on… but I got jealous. I seduced my brother every day so he couldn't have sex with his girlfriend, and I squeezed out his sperm until his balls were empty. My brother lamented that he couldn't have sex with his girlfriend, but I was happy.
