It was an honest admission to my nineteen year old stepson that I would not refuse him, not tonight, not tomorrow, not ever. By tellingRobert thatI could never say 'no' to him, I was actually making a commitment to my stepson. I wascommitting to allowing him access tohis stepmother's pussy for the rest of his life. I don't know if this commitment was lost on him, but at that moment I knew I would never deny my stepson access to mefor the rest of his life. I belonged to him! 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. While I was caressing and kissing him, a thought re-entered my mind. I wanted to test whether or not the thought of impregnating me aroused him, or if it scared him. Was the risk of getting his stepmother pregnant part of the excitement and allure of the torrid affair that he had imposed on the two of us?

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 andgroping 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. I softly ran my fingers around the ridge that separated the glans from the meaty shaft of his cock, barely touching him. The head of his erection swelled and pulsed in response to my very soft touch.
