Betrayed by her best friend, Susan gave up and, reluctantly and slowly, she unbuttoned and removed her blouse. She reached back and released her bra, her breasts bouncing and jiggling as they were released. Jean, who had seen them more than a thousand times, was impressed anew by their perfect shape, the round mounds topped by large, rosy and erect nipples. Somehow it was different seeing her strip in these different surroundings and circumstances. The short skirt was next, and, as it came down, the eyes naturally followed along, down from bulging breasts to the deep navel, to the triangle of puffy blond pubic hair. Susan stood there, nude except for her long hose, two pair of eyes absorbing the seductive sight - a pretty blond woman, naked and vulnerable. For Susan, the feeling was indescribable. Being forced to strip, knowing that she was going to be spanked - and in front of Jean - both humiliated and, as usual, aroused her. She just stood there, waiting for the next command, which wasn't long in coming.
"Ok, Susan, you've been a cock teaser again and are going to be punished. I just got the leather whip and handcuffs out of my suitcase and they're ready to use. What do you think of that?"
"Oh, Robert, please, not that thing again."
"No? What should I do, instead?"
"Just spank me with your hand - I didn't mean to tease you!"
"Oh, yes you did! Now, if you don't want the whip, beg me.
Susan was horrified anew at Jean's presence, but was desperate to avoid the whip. So, with tears flowing again, she dropped to her knees before him and beseeched him, "Please, Robert, spank me with your hand, not the whip. I really didn't mean to upset you. Please!"
Seeing Susan naked and by herself, Jean had always been impressed by her perfect figure, everything in proportion (except, perhaps, the tits). Seeing her standing in front of Robert, however, she realized again, just how relatively small she was - he towered over her when she was dressed, but her nakedness accented the difference in size, making her look delicate and vulnerable. As she sank to her knees, kneeling servilely at his feet, Susan looked even more defenseless. It was an arousing sight, almost like a play in which a slave girl grovels before her master, begging for mercy. Jean felt a tinge of remorse as she saw her friend so humbled, but that slight regret was wiped away by a surge of perverted excitement that sent a tingle through her body. She wanted to see Susan humiliated and spanked, and any guilt that she might have felt was assuaged by the realization that Susan, herself, was aroused by that humiliation and by being dominated.
"All right, Susan, get up and come over here!" Throwing the whip onto the table, Robert sat down on a chair and, as Susan came over, he told her to lie over his knees. Without protest, but trembling slightly, she did as ordered, draping herself over him, her head hanging on one side, her legs on the other. As always, she presented a sensual picture of a beautiful, subjugated woman, ready to receive punishment from a dominant man.
Jean had seen Susan in that same pose with Don, but, somehow, this was different. She looked the same - her large tits hanging down, quivering, her hips curving upwards into luscious mounds and her long legs stretched out toward the floor - but having a different man ready to administer the punishment changed everything. In addition, Jean was only a spectator, not directly involved, a difference that led her to be more observant, more able to take in details she ordinarily would overlook.
For example, as the spanking began, she noticed the way that Susan's breasts jounced as he ass was hit, elongating for an instant, and then rebounding and quivering, almost as if they had a life of their own. Also, with each slap, her legs lifted up, her feet leaving the floor, only to drop back between spanks. Most importantly, her ass cheeks were flattened almost completely as Robert's large hand descended, and then surged back upwards as the pressure eased. However, like aftershocks in an earthquake, they continued to pulsate up and down, each movement less than the one before - until the next blow started the cycle over again. At first, the action was chaotic as Susan squirmed and twisted, struggling to minimize the pain, but as her resistance faded, the spanking fell into a rhythm, the movements blending together into a graceful pattern that was fascinating to watch. (Incidentally, it should be noted that Jean also did some squirming in her seat as the drama unfolding began to heat up her cunt!)
For Robert, as he prepared to spank Susan, the rounded hips draped over his lap created some sexual heat also. Unlike that first time when she had seemed to be only another cock teaser, he was not really angry with her - the need to punish her was more a matter of principle. In addition, having a pretty (and naked) woman kneeling at his feet, pleading for mercy, will have a profound affect on any man - he'll certainly get a heady sense of dominance, of mastery, of superiority, which leads, in turn, to a feeling of beneficence, a desire to be magnanimous to his poor, weak subject. There is a temptation to lift her up and forgive her - and take her to bed! Presenting one's self as such a frail and impotent slave or concubine has been a woman's effective defense throughout history, but Robert stalwartly avoided that seductive trap and began the chastisement.
