When I got home, my younger sister and her group of high school girls were having a slumber party. Their friends got excited seeing their older brother. Eventually, the topic turned to sex, and they decided to play King's Game. The lewd commands escalated, and that firm, youthful body was irresistible! I can't let my sister see me like this, all drooling and pathetic! What? I never thought I'd have sex with my sister in front of a friend!
