Mary had not noticed. She really had not noticed! The girls looked at each other in delight. Mary had not noticed the change. The girls certainly had. It had been seamless but now, instead of the black strap-on dildo with its splayed edged helmet all moulded in plastic, a real penis ploughed back and forth in Mary's vagina. Not a simulacrum but the real thing, a penis that could spurt real semen -- real fertile semen.
The girls squirmed in delight, their fingers even busier between their thighs. The excitement, the erotic excitement of it; they might even be witnessing a conception. It was possible -- it was a risk. Not their risk but Mary's. Back and forth went the long and so real flesh staff. Mary unaware, was staring ahead, eyes wide as her orgasm built. Lovely Mary with her virginal white skin and peaches and cream complexion; tall Mary, overbearing Mary, bossy Mary. They had done it -- or Edwina had -- the switch had been made. How long would it or could it be until Mary noticed? The girls had agreed it should not be short, not a quick in and out but could they make the full five minutes?
It had been a complicated process to get Mary to where she was now. It had not been easy persuading little Clarie. She was not into the girl scene; but she was the bait, the little fish to catch the big one -- Mary. Edwina knew how keen Mary was on the petite girl. Knew she lusted after her.
The five minutes were up. The girls had almost won. Little demonstrative gestures of triumph. They were not quite there yet. But now the real penis had to be removed and replaced without Mary noticing. A second changeover.
Edwina motioned for Michael to step back. The long and very black -- and very wet real erection slid out from Mary. The girls stared at its end, an anxious moment. Had Michael come, had his knob exuded? It seemed not, or not anyway a full load of cream. There might have been some exudation. Some risk that Mary had been inseminated, some spermatozoa might be swimming within her vagina, seeking an ovum.
"No, don't pull out Cynthia, keep fucking me. I'm almost there. Please." Michael looked quizzically at Edwina, raising his eyebrows in question. Edwina's head shake definite. No more. Michael must be denied. Mary's hands were scrabbling behind, reaching for the supposed girl with the strap-on dildo. The girl Mary thought had been fucking her for the last five minutes. She did not see the tall young man with the erection being hurriedly ushered out. Girls' fingers reaching to touch his hard cock as if for luck. A cock so upright and glistening with Mary's wetness. His reward would come later -- yes, he would come, his semen would exude, his pleasure would be intense. It would be his choice where he made his deposit -- anywhere or in anywhere but Mary.
Tall Cynthia, her long hair tied back, her nipples hard points on her small breasts, reached for Mary's buttocks and drove the long black strapless dildo back into Mary -- balls deep, well, had the dildo possessed balls. It did not but Michael certainly had -- two big ones! And it seemed as if they had come close to unloading. Cynthia resumed her pounding of Mary, acting the man. She was, after all, tall and strong, chosen because she and Michael were not dissimilar in build.
Lovely, haughty, just so lesbian and man hating Mary. Contemptuous of men, absurdly feminist and proud of never so much having touched a penis let alone been fucked (or rather 'fucking a man' as she hated the idea woman are fucked and men do the fucking) Mary had now been fucked by a man, a young man of impeccable maleness, a man with not a hint of the androgynous about him, a man of virility and proud, yes, upstanding and erect masculinity had pummelled her from the rear and she had not noticed. Was unaware, completely unaware, her vagina had hosted a large black cock, not plastic, wood or glass but real flesh and blood for five whole minutes. Had, very likely, been close to being inseminated.
What if Mary had noticed? The shock, the delicious perhaps 'popping' sound as she had angrily pulled from Michael. The look on her face as she stared at Michael standing there naked, his beautiful strong muscular body shining with perspiration and that so big cock of his upright and coffee knobbed, perfectly flared and with that intriguing dimple where the semen came out. She would have been just so angry. Incandescent with rage. That might yet happen. Had Edwina not got photographs -- photographs which should so clearly show Mary with a penis inside her. Photographs, moreover, movie film taken so there could be no doubt the incident was real not faked -- no question the man had been there and inside, not placed by photographic manipulation replacing Cynthia and her strap-on.
But now there, naked and still bent over the polished wood of the table, was Mary, arms outstretched along its surface, fingers opening and closing, lost in pleasure. Stretched out with her long legs so apart, her beautiful rounded bottom so very there as Cynthia fucked, the black strap-on dildo -- so appropriately black -- disappearing and appearing from her wet hole. Possibly an undignified position. Certainly, Mary had waxed long and lyrical about the positions of sexual intercourse -- not that she would ever permit a man... Had talked about how degrading it was for women to adopt a subservient position; being fucked from behind like an animal being about the worst -- had decried the use of the word 'mounted'; had not found much good to say about 'missionary' -- again the so awful, so wrong way that men penetrated and women accepted; how women received the semen offered or given by men; and as for kneeling and sucking a cock... Mary was incandescent at the image of subservience; the image of a women kneeling, any woman, to accept a man's cum in her mouth. And swallowing -- urgh!
The girls had become fed up, annoyed even, at Mary's constant degradation of men. They had undoubtedly enjoyed the lesbian sex, given their circumstance of being mostly locked away from male company. But actually, despite Mary's lecturing, that was what they really wanted. Male company -- naked male company.
'Teaching Mary a lesson' had become a favourite theme of conversation when she was not around. They would like, really, to have her tied up and introduced a man into the room -- or men. The thought of Mary being held down kneeling -- by the girls -- and them introducing a cock into her mouth, greatly pleased them. No way she would suck but if kept open by force it was not beyond the girls' ability with their soft and delicate feminine fingers to stroke the man's penis into doing what men did and in Mary's mouth. She would have to swallow. A man's cum in her stomach. That idea very much pleased the girls.
