Over a period of a few minutes, Robin’s own excitement continued to build as well. “Steve, please fuck me now. I want you all the way inside me.” With her legs, she pulled me forward. Drawing a deep breath as I pushed past her maidenhead, she tensed for a few moments, then relaxed. I had taken my sister’s virginity.
I knew I could not last much longer, so I began to work my cock deeper and deeper into Robin. Whatever she lacked in experience, she made up for with enthusiasm. She gripped my back and neck with her arms and locked her legs around my waist. “Steve, please give me a baby. Cum in me now!” And with that statement, she squeezed me with her arms and legs as if her life depended on it.
I could not last any longer. Her orgasm pushed me into a level I had never known. As I began to cum, Robin pulled me tighter and tighter. I felt my hot seed erupt from my balls into the deepest part of Robin while my entire body seemed to orgasm. I was impregnating my sister.
We lay there for the better part of 15 minutes, her breasts to my chest and her stomach pressed close to mine. Nuzzling our heads with another, we intermittently kissed each other. Slowly, my cock shrank until only the tip remained. We never said anything. I raised myself on my elbows and we continued to kiss softly, gently.
I rolled over and took her into my arms. Laying her head on my chest and draping her legs over mine, she quickly went to sleep. I soon followed.
For the next several nights, she stayed at my apartment. We repeated our sessions during the weeks to come, even after she confirmed that she was pregnant. To our friends and co-workers, the party line was that she was artificially inseminated. They seemingly accepted it, although I suspect the announcement generated some gossip in my office. Robin continued to meet me for lunch, which I am sure only added fuel to the fire.
Nine months later, Robin gave birth to a baby boy. She couldn’t have been happier, and I couldn’t have been prouder. Today, I am his doting uncle/secret father. I treat him like a son, which of course, he is.
Robin and I still get together at my apartment. We have stayed exclusive to one another over the past few years, and the excitement that we felt that first night still lingers even today.
Who knows? Maybe my son will get a little sister.
