Training my younger sister in progress. Am I a pervert for training my younger sister into a sex toy while my parents are away? Winter Aikoto Sound YSN-655

While my parents were out, I spent a long time training my younger sister, "Qinyin," to be my personal sex toy. She used her innocent face to hold my prized, large penis, her tight little hole gripping me so tightly I felt like I was dying of pleasure. Now she even lets me ejaculate inside her whenever I want. At this rate, she'll probably get pregnant someday, right? Just thinking about it makes me both nervous and excited; my penis is still hard.
