Susan's spontaneous reaction was to beg, "Please, Robert, don't do that! Please just use my cunt!" (Later, as she recalled that request, she was mortified and embarrassed all over again - asking a man to use her cunt!)
"Haven't you been ass fucked before?" he asked as he began to push his cock head against her. Then, before she had time to react, decide what to say, he went on, "Hasn't Jim ever had you here?"
Relieved, she blurted out, "Of course not! He would never think of it!" A true statement, of course, but hardly a full answer to Robert's real question - fortunately!
He, naturally, had no intention of stopping, regardless of her answer, but said, "Just relax. I'll take it slow." True to his word, he eased his cock past her sphincter and began the inexorable entrance into her ass, sliding in, backing out, sliding in further, backing out less, until, finally, he was buried in her anal passage up to his balls. He then began the fucking process, slowly entering and withdrawing, the motion gradually building up until, as he approached his climax, his hips moved like a jackhammer, pounding her without mercy. By that time, however, Susan wanted no mercy - she wanted to be crushed under his assault, wanted to be hammered to orgasm.
As we know, of course, Susan was not - a virgin when it came to anal intercourse. When Don had first penetrated her ass in Maine, it had been a shock, but, by the time that first episode was over, she had discovered the pleasure of that aberrant sexual practice. Since then, Don had ass fucked her many times to their mutual enjoyment, but this sodomizing was different. With Don, and with Jean involved, the act had been part of an enjoyable, voluntary sexual interlude, but, now, she was just being taken and used. She was tied open below and her upper body was forced downward by the pillow under her abdomen, leaving her defenseless and unable to move. It created a complete sense of vulnerability, of being absolutely under Robert's control. However, as had happened so often in the past, being controlled, dominated, had the perverse effect of arousing her. As she lay there, helpless as he began to enter her, that feeling of being used, being a slave to his desires, had the usual magic effect and, involuntarily, her body cooperated in its ravishment - if that's what it was. Tension disappeared, her sphincter relaxed, her anal passages welcomed the penetration and, in general, she became an active participant in her own buggering.
However, "active" did not mean a great deal of movement. As the cock pushed past the sphincter, she was able to take her hands away from her bottom and moved her arms back over her head. As the fucking commenced and became vigorous, she grasped the edge of the table to hold herself in place as Robert moved very forcefully in and out of her. In that position, however, legs tied wide open, hands gripping the table, she was unable to make her usual pelvic undulations as she became more excited. The angle of her crotch was such that his balls smacked against her clit each time he pushed inward, sending waves of pleasure into her cunt, but she couldn't even push back effectively. Instead, all she could do was lie there and be pummeled, but, perversely, again, even the inability to move fed the fires building up inside her. That restraint merely reinforced the feeling of being dominated, controlled, and the submissive part of her personality exulted in that, relishing the additional evidence that she was a mere tool to be used by her master. These were not conscious reactions, and in calmer times, she would have furiously rejected such servile behavior, but in the throes of an incipient orgasm, they seemed appropriate, even natural.
Robert, of course, had no such psychological permutations; he had his cock buried deep in the ass of a lovely woman, fucking her with all his might, which was all that mattered. As he approached climax, he leaned forward, pushing her further down into the pillow, putting all of his weight into the pistoning in and out of her stretched asshole. Finally, the crisis was reached and his cock exploded deep within her ass. At the same time, Susan was in the midst of a long, almost continuous orgasm - no violent undulations, no thrashing around, just a stream of internal convulsions that were among the most satisfying of her life. Her cunt was empty, but, nonetheless, she felt as if waves of pleasure were emanating from it. At the end, she squeezed inward, both with her cunt and ass, causing even greater pleasure for Robert as her sphincter tightened around his cock. When he had ejected the last of his cum into her, he fell forward, satiated, flattening her even more, but even that added to her feeling of being dominated and she had one last convulsion before she, too, was sated.
As his cum jetted into her, Robert stayed rigid against her hips for a few seconds, and then slumped forward over her back. He stayed there for close to a minute, recovering, his deflating cock still buried in her asshole. Finally, he straightened up, slowly withdrawing from the now commodious opening, and looked down. He saw a dark red, quarter-sized aperture, going deep into her body, the still dilated asshole looking like a round, wet funnel, ready to welcome another penetration. The skin around the hole, usually puckered, now was stretched taut, shiny and smooth, glistening with the cum that had followed his cock out. He watched with fascination as the stretched sphincter gradually began to contract, the opening to close, and the normal puckered appearance beginning to reappear. Suddenly, he came to his senses, realized that Susan was still spread-eagled over the table, beginning to struggle to get up.
Bending down and releasing her ankles, he reached forward and, taking her by the shoulders, helped her to rise. Susan stood there unsteadily, her legs, strained from being held wide open for so long, didn't want to come together. In addition, her entire cunt area felt swollen from the whipping and the subsequent ass fucking and, to make it worse, her upper body had been bent down and flattened the entire time, making it hard to straighten up. "Are you all right?" Robert asked solicitously. Susan finally was able to stammer out that she was ok, but her thinking was still fuzzy, not knowing just how to react to the unbelievable experiences of the last hour. The pain, the humiliation, the embarrassment, all had contributed to one of the strongest orgasms of her life, but that, itself, was embarrassing! Oddly enough, there was little of her normal feelings of submissiveness usually followed a spanking or other such punishment. Certainly, a man who had tied her down, whipped her and then sodomized her would have her as an abject slave, at least until the feeling wore off, but not this time.
So, while Susan was flustered and confused, she slowly regained her equilibrium and was able to reply more firmly, "No, I'm all right. Just let me sit down for a moment." Then, "Ouch!" as she sat down hard on her very sore bottom, a painful reminder that something significant had occurred before the ass fucking.
