woman laughed softly.
'Forget about such things for tonight, Lesley. Turn over and show me your behind. Ah, yes! I think our guests will find the next hour or two of the lecture most stimulating!'
I report the very words, Charlie, spoken not an hour since, for in my innocence I had no notion of what to expect. When the curtain was drawn back and Dr. Jacobus stepped forward on the dais again, the scene had changed a little. Lesley was re-attired in tights and singlet, but now she lay face down over a stout leather bolster. Her seat was well raised and broadened by this. Her hands were held at full stretch ahead of her by the wrist cuffs. Leather anklets held her long, trim legs to the opposite rim of the marble demonstration table.
'Gentlemen,' said Dr. Jacobus, 'we have considered our subject from one view, let us now consider posterior possibilities.'
In her present pose, the tantalising film of the tights showed Lesley's seat-cheeks swelling firmly, and marked the dusky cleft between them. Dr. Jacobus drew his lecture cane over these contours, which contracted instinctively at the touch. The learned doctor showed how an active young woman in her middle twenties, her maturity firmly controlled, was often at her best in this area of her charms.
'In Lesley's case,' he remarked, 'regular penis exercise in the marriage bed and carefully controlled pregnancy has given a taut, proud maturity to her bottom-cheeks without making her in the least flabby.'
I could not see the other guests, of course, as Lesley turned her moody, fair-skinned face with a shake of her fringe. Yet, from the sudden look of apprehension in her blue eyes, I believe she must have seen the twenty middle-aged gentlemen looking expectantly at her, each displaying his own interest at the ordeal she was about to undergo.
'In nature,' said Dr. Jacobus, 'Lesley's bottom has three uses. For a man, the most important is performed by her anus, which is made as a tight and enjoyable entry for the penis. Those who prize such tightness, and those who enjoy spending in a girl's body without fear of engendering a baby, will make good use of her in that way.'
At this point one of the scholars interrupted with a question.
'Risks?' said Dr. Jacobus thoughtfully. 'When she chose to bear a child, Lesley thereby diminished the tightness of her cunt. Some men who value tightness will now, understandably, demand the use of her anus. Lesley surely has only herself to blame! She was eager for her husband's penis and so became pregnant. Carrying a baby in her belly made her prone to certain trivial afflictions of her rear dimple. Perhaps she remains vulnerable there. Yet that was the cause of her own randiness. Lesley must not expect to deny us our pleasures because of the consequences of hers!'
Dr. Jacobus returned to his theme. 'The second purpose of Lesley's backside is to receive chastisement. Scholars through the ages are of one mind that no part of the female anatomy is better suited to this than the buttocks. Since Lesley will never be set at liberty from her fate as a slave girl, we need have no hypocrisy here. She will be chastised by her master on her bare buttocks and the duration of this will be determined solely by his enjoyment.'
Lesley pulled vainly at the leather anklets and wrist cuffs with a wail of protest.
'Finally,' said Dr. Jacobus, 'her behind was made for woman's ease as well as man's pleasure. That subject concerns us only in so far as she may plead her needs as a pretext. It is, of course, a simple matter to deny such a performance or, indeed, to compel it by means of a loaded squirt. Yet she will no doubt try to end a caning or prevent her master's entry by protesting the urgency of her situation. Happily this may be easily checked.'
Now he turned to Lesley and took hold of the waistband of her tights. As he drew it down to her knees, the pale hip flesh swelled free a little. Now we looked down on the slight, taut maturity of her pale hips, the gentle firming-out of her bottom-cheeks, and her long, trim thighs. Despite her twenty-eight years and her promiscuous ways, the young wife lowered her face from our sight, for now Dr. Jacobus pressed her two rear moons apart and displayed Lesley's anus. The tight, dark bud shrank from his finger's touch.
'Lesley pleads that she has never had a man that way,' he explained. 'Alas, she does not realise how greatly that will make the buyers covet her in the slave girl market!'
He stroked Lesley's fair urchin crop as if to calm her. Then he took a glass squirt about eight inches long and slim as a pencil, with a rubber bulb at one end. He filled it from a bottle of liquid soap. Next he sat on the table's edge, firmly circling Lesley's waist with one arm, and looking down at the taut swell of her seat. The skin of the cheeks, where they curved in to meet at her anus, was ivory-yellow, in contrast to the pallor of her buttocks.
The neat inward dimple of Lesley's arse tightened with alarm at the touch of the cold glass squirt. Dr. Jacobus laid the squirt down. With all his power, he delivered a series of ringing smacks upon the full, pale moons of Lesley's bottom. The promiscuous young wife was soon gasping, tensing, and shifting her seat-cheeks desperately. Then she bowed her head, hiding her face, and yielded her anus to the slim probe.
'Opinions vary,' said Dr. Jacobus, 'as to whether vaseline or liquid soap will best prepare a young woman like Lesley for love. For her lover, the convenience of merely vaselining her is clear. In the present case, where we are dealing with an adulterous young wife, there is an element of punishment. The length of the glass squirt and the jet it expels will stimulate needs and sensations deep in Lesley's backside. Also the light perfume will cause a slight erotic irritation.'
The full length of the squirt was now sheathed in Lesley's bum, only the black rubber bulb nestling between her hind-cheeks.
'Lie quite still, Lesley,' said Dr. Jacobus calmly. 'You must learn to accept these measures of harem hygiene.'
Those who had suffered the arrogance of the young wife would have relished the face which Dr. Jacobus obliged her to turn to us. The arrogance had gone from the blue eyes. Where was the sulky, self-possession of her clear, fair-skinned features and firm mouth? He squeezed the black bulb lightly and her body tensed at the first muffled squirt. There was a sudden wild-eyed and open-mouthed alarm in her face. Our haughty young woman seemed to scan the rows of chairs imploringly for someone who might intercede on her behalf. She saw only twenty eager faces. Dr. Jacobus tightened his arm 'round her waist. He pressed the bulb hard and repeatedly. With a forlorn cry, Lesley jammed her legs harder together and tensed her pale bum-cheeks on his busy fingers. When he had done, he withdrew the glass probe. Lesley's anus went desperately tight and small as the glass tip came clear.
'First, gentlemen, let us consider the amorous use of Lesley's behind. By her promiscuous conduct, she has lost all right to object to its use in this manner. Having surrendered herself to her urges, it is only right that she must surrender to those of others.'
There was a ready murmur of assent to the justice of these remarks, for who could dispute so moral an argument? Dr. Jacobus resumed. 'We are fortunate in having as our demonstrator one whom I will call the Schoolmaster. He has long been an admirer of Lesley's backside as she bent to some task in a pair of tight riding jeans. Then, alas, she was not a slave girl and his lust had to be curbed. Let us concede, however, that he is not a favourite with her. He lately administered severe chastisement with his cane to the bare buttocks of a favourite of hers, her daughter-nymph, while our boyishly cropped Venus was obliged to listen in the next room!'
This at once made the situation more provoking! The Schoolmaster appeared in a mask and a waist-length leather jerkin. His phallus, understandably stiff with expectation, stood out and nodded as he walked. He adjusted a mirror so that he would be able to see Lesley's face while he ravished her arse. Sitting on the side of the table, he circled her waist with one arm and looked down on the full, pale swelling of Lesley's wifely young seat-cheeks. 'Your face to the mirror, Lesley,' he murmured. 'Watch yourself being prepared. Try to imagine how much a man enjoys doing it!'
He took a large blob of vaseline from a jar and slowly spread it on her tight inward rear dimple. In her agitation, Lesley twisted her head, looking back at him beseechingly. Her blue eyes interceded forlornly. The sulky mouth whispered peevishly those reasons which made her behind so vulnerable to ravishing. He smiled at her with amusement.
'That's your problem, Lesley! My prick is so stiff that I could not desist merely because you may be inconvenienced for a day or two! Such shrewishness, Lesley! Your right to choose who beds you? Your body belongs to you? Surely you forget where you are! Such mischievous nonsense is never tolerated from a harem slave- wife!'
His finger diddled the urchin-cropped Venus between her buttocks as she lay on her belly over the rubber cushions. He fondled the smooth, erotic maturity of Lesley's bottom-moons, which were swelled out and broadened
