When Nonoka first joined our family, I thought she was a good girl with a bright personality. But after a while, her true nature started to emerge. She treated me, her stepbrother, like a toy. She would sit on my face, almost suffocating me, stroke my dick, suck it, and chuckle as she brought me to the brink of climax. She even rode my penis without a condom and did a rodeo cowgirl. I was a bit hesitant at first, but Nonoka mouth and pussy felt so good that I got addicted to it.
