A Stepmother's Sin - Chapter 5: I try to understand what is motivating my stepson

"Baby, if I had known someone like you when I was in college, I likely would have gotten knocked up before my eighteenth birthday. I could never say 'no' to you." It was an honest admission to my nineteen year old stepson that I would not refuse him, not tonight, not tomorrow, not ever. By telling Robert that I could never say 'no' to him, I was actually making a commitment to my stepson. I was committing to allowing him access to his stepmother's pussy for the rest of his life.

I leaned forward and took one of his nipples in my mouth sucking it, much the way he had sucked my nipples last night. I kissed his chest, and massaged his erection through his pants.

His penis was partially erect already. Robert kneeled in from of my, separated my thighs, and he kissed my pussy through the wet material of my panties. I lifted my bottom up to allow him to remove my panties. He sat back down next to me. We were now both naked, necking and groping each other on the couch. To me, there was something sexy about being naked outside of the bedroom. I can’t quite explain it, but it added to my excitement. As we necked on the couch, I lowered my hand into his lap and found his penis. Robert’s erection was large, rigid and standing straight up on its own. God, he was sexy, no question about it.
