My beloved brother got a girlfriend... I was jealous, so I let her ejaculate every day until my balls were empty so I couldn't have sex with her.

I got a girlfriend as my favorite older brother in the world. I thought that we, the brothers and sisters, would always be the same for the future... but I was jealous. I seduced my brother every day to prevent him from having sex with her and squeezed out the semen until his balls were empty. My brother lamented that he couldn't have sex with her, but I was happy.
