I secretly made my younger sister perform oral sex on me, hiding it from my parents, and even wrote about my feelings in my diary. From a young age, I was taught that oral sex between siblings was perfectly normal, and I still wholeheartedly believe it and obey her. Every day, my sister's oral sex skills improved! Recently, she's become even more erotic, even performing oral sex in blind spots where our parents can't see! It's truly awful! However, the thrill of being discovered by my parents, who are so close, brings the excitement to its peak! In the end, we crossed that line, and we couldn't stop ourselves from falling into the mire of incest… To my sister, anyone would do this as a matter of course as a sibling, so she was completely innocent. But, knowing the truth, to be honest, I still feel a little guilty.
