My older brother, the one I love more than anything in the world, got a girlfriend. I thought we'd be together forever, but I was jealous. I seduced him every day and milked his balls until they were empty so he wouldn't have sex with his girlfriend. He complained about not being able to have sex with his girlfriend, but I was happy.
