***** It's funny and a bit ironic that so many of the readers who commented on the previous parts of this story, noted that the relation of Bobby and Tish, was one of being "half-siblings," and not "step-siblings." That was the big issue that concerned a number of people. The subjects of coercion, incest and rape were casually accepted. As usual, I will accept all of the blame for any misspellings and literary mistakes. When I get tired of all of the two-fingered typing, the structure can seriously degrade. Take it for what it is intended to be or pass it by altogether. If you're still with me, please enjoy! ****
I hesitated for a brief moment, my brows furrowed and a slightly confused look rippled my grin. Seeing my indecision, his soft hand reached for my blonde locks and he pleasantly combed his fingers through my lush mane. It felt so nice to have his strong hand brushing through my tussled hair. He saw my posture relax as I permitted him some unaccustomed erotic closeness, that a mother would not normally concede to a grown son. Then I felt his hand gliding slowly and caressing the tingly skin at my neck and apply a bit more pressure to my nervous shoulders.
Just a minute before, my son had eased towards the front door, with me anxiously following in his footsteps, and stopping at the entranceway. He was preparing to take his younger half-sister shopping, when he paused and turned back in my direction. "Before I leave, how 'bout making me smile?" That was the statement that had so perplexed me and caused me to freeze in place. For an instant, I imagined that he wanted me to smile at him and maybe kiss his forehead as I'd done on so many occasions when he walked out the door as a young boy.
With the continued downward motion exerted on my upper torso, I snapped-out of my momentary daydream and instantly understood the implied directive and allowed my knees to collapse. "That's right," he grinned, as if this old dog had learned a new trick. "You know where you belong, when I want you to be a good girl." My head merely nodded and I went about my assigned task accepting that this would now be a major part of my daily routine.
I was on the carpet between his legs and with an instinct, learned and practiced over the past few hours, I knew to unbuckle his belt, then unbutton and unzip his pants and tug the denim material down his firm thighs and come face-to-face, (so to speak,) with his rapidly inflating cock. But something strange had taken place overnight, that I was adjusting to more and more, the erotic idea of settling-in to the role of submissive sexual partner to a dominating force, (and in this extreme case, to an incestuous one.)
This illicit chore was no longer the repugnant, demeaning task that only yesterday, I had been forced to endure. Now, I seemed to appreciate the fact that I could be a sexual turn-on to my young son and that he was fulfilling my sensual hunger from being abandoned and "an unfinished product," in the prime of my sexual maturity. I welcomed the chance to learn and experiment in the taboo arts of manipulation and perversion. We had essentially sealed a pact of perversion, where he would provide security and financial wherewithal, if I accepted the proposition that he gained exclusive and undeniable possession of my body.
It wasn't the type of contract that I would proudly proclaim and I wouldn't wish that its details ever become public, but we both had something of value that the other one wanted. I was beginning to understand my position and his leverage, so I determined that my wisest course of action would be to make the best of the situation, which meant that I quickly get on his good side and that I learn to enjoy what I'm called-on to do. I took his large meat-stick into my small hand and gathered my breath, plastering a contented smile on my face and proceed to the business before me. I readily stroked the firm tool in my greedy palm and planted a series of warm wet kisses up and down the tremendous length of his prodigious shaft. And his eager humping of my willing mouth, showed me that I was progressing well, in my crude education.
During the exhaustive tutorial of the night before, where I had been lectured and shown just how I should fondle and arouse his swollen appendage, I came to appreciate the engorged member that would for the next year or more, provide the sexual relief and satisfaction that, up until now I hadn't realized that my yearning psyche had been missing. During the quieter hours of the evening, I had taken the time to study his impressive organ up close. It grew from a thick, dark patch of curly black pubic hair, where his scrotum hung like heavy ornaments in a weathered, leather pouch. When I cupped them delicately or swirled them on my tongue, I could sense each individual orb as it filled-out the restrictive reservoir. I knew that if I squeezed this sex sac, or in any way caused it harm, I could gain a measure of revenge, but then I figured, "What the hell good, would that do for me?" So, my next step was to learn just how to fondle and caress this squishy pleasure center of his, so that our time together, would be beneficial to the both of us.
On further tactile examination, my fingers would slowly glide over the rubbery skin of his swelling shaft while it was still expanding, but as it engorged and grew more solid, the taut flesh would become roughened with the subcutaneous outcroppings of the blood vessels and bluish veins that crisscrossed the extensive length and girth of his steely pole. For the moment, I was only concerned with his arousal and that freed me, to actually discover why it made him feel so good. With each slight movement of my hand as I searched for his tender regions on his cock and balls, I sensed his sudden intakes of breath and felt the tiny shocks as his organ literally hopped in my grip.
