After my son left home his younger sister told me how he had raped her two years before. Once that secret was out, she continuted to tell me what he and she had been doing since then.
Our parents worked late. My hot, seventeen-year-old sister, a real tease to my friends, was in my sex fantasies. I was fifteen, super horny and happened to sport a big, nine-inch cock. I jacked three to four times a day. (Oh, to be young.) Seeing her parade around the house in just her thong panties and midriff tee-shirt was more than a young teen could handle--even if she was my sister. I will detail how I found myself crossing the line, doing things no parent should know about.
