Exclusive 3rd bullet! Kiho Ichinomiya drama for the first time! My house had no electricity or gas, so I decided to live at her house. She has her sister, and I'm meeting her for the first time, but she... looks like she's wary of me. That night, she refused to have sex with her, and when she was masturbating, she was seen except by her sister! My girlfriend's little sister seems to be vulnerable to her pushing, so maybe I'm going to do this... I secretly fucked her sister for a week. Gradually, her sister's temptation escalates.
