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

... vulva. Our tongues danced together, chasing each other from my mouth to his, and back again. As we kissed, he reached behind me and unzipped my dress and let it fall to the floor around my ankles. I stepped out and kicked it behind me, without breaking out kiss. I stood there, naked from the waist down, wearing only a bra and boots, my panties having been discarded in the kitchen, and my dress on the landing at the top of the stairs. Robert reached behind me to remove my bra. He was monetarily puzzled by the fact that there was no clasp in the back. Quickly, he realized the clasp was in the front, between my breasts. He was very adroit and he released the front clasp with one hand. My boy had obviously practiced this 'one handed move' many times before. It did bother me that my stepson was far more experienced than I was. Robert stepped back, slowly and seductively pulled both cups apart, freeing my breasts and exposing my very erect nipples. I realized this was the first time he had actually seen my breasts exposed. In fact, since he was not my biological son and I had not nursed him as a baby, this was actually the first time in his life he had seen my breasts bared.

Looking at Robert as coyly as I could, I said, "Okay, baby, if that's how you want me to, I will leave them on for you." I got up and caught my image in the mirror. I was taken by a very sexy looking woman, naked except for her high heel boots, the only vestige of modesty being the thin, very blond, almost transparent wisps of fine pubic hair covering her pussy. I still looked good at age thirty nine. Many people have told me that I look a great deal like Reese Witherspoon. Honestly, I could see the resemblance. Yes, even I had to admit I was a sexy sight indeed. I went to my night stand and retrieve my diaphragm, which I filled to the brim with spermicidal jelly before squatting down to insert it in place. Robert was mesmerized by my preparations. His erection arched noticeably as I held my vagina open with my left hand and inserted the folded diaphragm with my right. I assume he had never seen a woman insert one before. With my diaphragm safely in place, protecting my fertile womb from an invasion by Roberts sperm, I lay back on my bed as Robert approached me. I resigned myself to accepting him ...
