My friend's sister

"My sister is scary, so please don't let her make a fuss at home." On the way to her friend Koji's house, Kenji couldn't even imagine what kind of person Koji's sister was. Then, Kenji comes to Koji's house and meets Koji's older sister, Chiori for the first time. Adult sexiness... A smile that looks like it will envelop you everything...and an obscene body reflected in her loungewear. Kenji couldn't hide his heart pounding. Kenji is invited by Chiori to "come out anytime."
