A Step Mother's Sin - Chapter 4: It Spins Further Out Of Control

... enough to know who I want for my sexual partner; and I want you. I have for years.” The last statement sent me searching for a response. “Robert, I am flattered, and I understand your confusion. I am quite confused myself. But what we did, what I did last night is wrong by any measure.” I was standing with my back to my stepson as I spoke, ashamed. I was ashamed of my behavior and I unable to face him or look him in the eye. Robert then took my hand and turned me to face him, and said, “I need to show you something.” He stood back one step, and then he removed his towel, dropping it to the floor. He stood there naked in front of me. He was obviously quite emboldened from his success last night. He had a confident ‘don’t take no for an answer’ demeanor about him. It was strangely appealing. Since he was my stepson, it was also very wrong, but it was definitely appealing. “What on earth do you ‘need to show me’?” I was trying to react appropriately, whatever that would mean.

It was hypnotic. He cut my weak protest off mid-sentence, “Mom, this is the effect you have on me. If I react this way just thinking about you, this cannot be wrong. My body would not react this way if it was wrong” he reasoned. “Tell me that you do not have the same feelings.
