At first, I thought "Nonoka" was a bright and good child when she became part of the family. But after a while, her true nature began to show. She treated me, her brother by marriage, like a toy. She would almost suffocate me with her face, repeatedly tease me by stroking and biting my penis, and even ride my penis without a condom, enjoying the rodeo-style riding and hip movements. At first, I was confused, but her mouth and vagina felt so good that I got used to it.
