[HUNTC-465] My sister's 'oral rape' diary is a secret from my parents! I have my sister give me a mouth and tell me my impressions in a diary. An obedient sister who has been taught to take it for granted as a brother and sister since she was a child and still believes in it. My sister's oral sex technique that improves every day! My younger sister, who is becoming more erotic, escalates and gives me oral sex in my parents' blind spot!

I hide from my parents and let my sister suck me and tell me my impressions in my diary. An obedient younger sister who has been taught oral sex as a matter of course as a brother and sister since she was a child, and still believes in it. My sister's oral sex technique that improves every day! Recently, my younger sister, who has become even more erotic, has escalated and is giving me oral sex in my parents' blind spot! Seriously dangerous! However, the excitement level reaches its peak at the thrill of not being found out by parents who are close to you! In the end, we crossed the line, and we couldn't stop anymore and went to the swamp with incest... For my sister, it's a natural act that all siblings do, so I don't have any doubts. But I honestly feel a little guilty because I know the truth.
