The days when her sister's friends came to visit were also the most tiring and miserable times in her younger brother's life because all of them were extremely lustful. In the name of coming to hang out with friends, in reality it was mainly aimed at her big brother who was at an age where he was developing in all aspects. The girls always intentionally performed sexually stimulating actions in front of him and even boldly took the initiative to do things that couples often do. Just like that, there were 4 girls in total and each girl in turn had her innocent younger brother serving her sexual needs. How pitiful for him.
