IENF-414 King's Game, Me and My Female School Sisters, I'm the Only Man - Fujita Kozue

When I got home, my older sister from high school was having a girls' night out with her friends. Her friends were all excited to see me. Soon, the conversation turned to sex, and they decided to play "King's Game." The lewd commands grew stronger and stronger; her firm body was simply irresistible! I couldn't let my sister see me like this, nose drooping, completely soaked! What? I never imagined I'd have sex with my sister in front of my friends!
