I decided to take a day off from work today, using my paid vacation. As I was doing so, my younger brother, who was absent from his university classes, came over and started to play with me, which made me feel weird... We had sex in the morning for the first time in a long time. Since we've been in this relationship, I've been having sex with him sometimes when my parents aren't looking. It's been a long time since we've had sex, but my brother's sex life is getting pretty good. He's not supposed to have a girlfriend, but... why? Lunch. I'm not much of a cook, but I made a simple lunch using what I had at home. My brother ate all of it, saying it was delicious, as he had exercised all morning. It made me happy. After that, until my mother came home... again... I hadn't noticed in a while, but my brother's body had grown a lot, and many parts of him had gotten bigger. I think I'm going to be addicted to my brother's body.
