"Now we can continue the experiment in proper laboratory silence," Dr. Villiers said, his steely fingers tormenting her breasts again, while his relentless shaft drove in an out of her as relentlessly as a piston.
The pain became a nightmare of piercing, white-hot flame. Her breasts felt as though they were being torn from her chest, and she was sure her asshole would rupture at any moment. But strangely enough, her cunt was awash with the secretions of lust.
Villiers' breathing was harsher and choppier as he reamed deeper into her, his balls slapping against her buttocks as he finally sank the full length of his cock into her belly. Fresh jolts of pain traveled along her nervous system to her brain, making the previous agony seem like a mere itch.
Marcy was screeching and choking behind the soggy gag of her panties when Villiers stiffened, jerked back, and slammed in again. "Aaarrrrgh!" he grunted, and repeated his movements twice more before his cock quivered and shot its load of sperm splashing against her inner walls. His cream burned the raw tissue like scalding acid. But through the pain, and because of the pain, Marcy became aware that her cunt was contracting violently, producing an orgasm of shattering proportions.
"Ah-ha!" Dr. Villiers said triumphantly, and slammed into her more viciously than ever, sending such tides of excruciating pain crashing through her that consciousness faded in a haze of purple agony. She tumbled into welcome darkness, only faintly aware that he was saying, "Experiment completed successfully, but laboratory animal may have expired from the supreme pleasure engendered by it."
Marcy was awakened by something hard being slapped against her cheeks. She opened her eyes and wished she hadn't. Villiers was straddling her, beating at her cheeks with his blood-streaked, gooey prick.
"Ah, the little whore is waking up, brought back to the land of the living by the cock she loves!"
The gag was gone from her mouth, and Marcy cried out as she tried to move. "Ouch! Oh, it hurts it hurts!"
"This will make it feel better," Dirk Villiers said, shoving the shaft of his cock between her lips. "There is your pacifier. Suck on that for a while."
Despite the fact that it was covered with her own blood, and she hated to think what else, Marcy opened her mouth obediently and began licking and sucking the meaty flesh.
"Later, my dear, I will permit you to achieve the total degradation you seek by letting you apply that active tongue to my asshole in another fascinating experiment," Dr. Villiers said. "You'll like that, won't you, X-999?"
Marcy nodded, not because of any desire to do what he suggested, but because she couldn't help herself. Apparently she couldn't help wanting anything this man said she was to do. She didn't know why, but she thought perhaps it had something to do with his utter lack of human feeling. His cold ruthlessness made him totally unlike other men she had known, men who had desired her madly, and whom she had spurned with her cold, unyielding chastity.
"On second thought, it might be best if I sent you away," he said, while she licked his cock with avid lips and tongue. "We have achieved nothing together scientifically. I was so engrossed in my exploration of what a degraded creature you are, that I neglected to make the necessary observations."
"Oh, please don't send me away – please!" Marcy begged, knowing she didn't ever want to give up the marvelous sense of lustful degradation he aroused in her. "Can't you make your observations now, while I'm sucking you?"
He looked at her for a long moment. "Well, perhaps. If you do it well enough, I may reconsider."
Marcy didn't wait to hear more. She began to assault his cock in earnest. She licked the round, purplish head, teasing the tiny opening in its tip with the point of her tongue. Then she used her fingers to stroke up and around the huge shaft, massaging it as she held it out of the way so she could draw the ripe balls into her mouth and roll them between her lips. He growled impatiently, and her mouth quickly traversed the length of the distended organ to the sensitive glans, threatening it with just the edge of her teeth before drawing the whole monstrous thing down into her throat.
Villiers grunted and settled more comfortably over her face, resting his balls against her chin. Again and again her mouth sucked him in, taking the full length of his prick, then letting it slowly escape before drawing it in deep once more. The hot, greedy sucking of her mouth astonished Marcy, but she wanted desperately to make him yield to that pull. Something in his face told her she must do it all herself this time, and make it good beyond anything he'd ever experienced before.
She clutched at his ass cheeks when she felt the quivering that told her he couldn't hold out much longer. The tight sheath of her throat was spongy and wet, and it constricted strongly as she tried to swallow him down to her stomach every time he sank in. Suddenly a wild cry burst from his lips, and his cock throbbed and fountained like a geyser, filling her mouth and overflowing onto her chin and neck.
A low growl of intense pleasure escaped him as Marcy sucked gush after gush of hot, creamy liquid from his pulsing shaft. It spurted and splashed in her throat, and her stomach was soon filled with it.
"Ummmmm! Ummmm!" She made odd moans and whimperings around the thick prick, her cheeks puffed out like balloons. But she didn't stop sucking. She wanted this experiment to be perfect, so she wouldn't be sent away from her joyous torment.
Again and again, when he seemed to have stopped, she sucked more juice from his throbbing flesh. When he finally collapsed, she kept right on licking the drooping staff, until it revived and stirred with returning life.
"Tomorrow you will begin a new series of experiments to test your reactions to troilistic and collectivist sex," he told her, when he had recovered a little.
"Will I like that?" she asked, when he removed his swollen cock from between her lips and rested it on the tip of her nose.
"My educated guess is that you will like it very much," he said. "My two red-headed omnivores, Kyle and Karla Karlow, will be your co-experimenters. And I may as well warn you, they will quite literally devour you."
Marcy made a face. "Why can't I just stay with you?"
"Because it's not scientific," he said. "What am I to learn from a simple one-to-one, male-female relationship? Nothing! The next step in your development is to learn-troilistic and collectivist techniques. We must experiment with these in depth, because they are the sex of the future. They will soon replace the outmoded, static sex acts of today."
Marcy didn't know what he was talking about, and she didn't want to know. All that interested her at the moment was the hard cock he kept just out of her reach. "Please, let me suck you – again."
"No. There is one more task we must complete before I leave you. I must relieve you of a certain condition that is an inconvenience to you and of considerable scientific interest to me – namely, your virginity."
Marcy was surprised. She had almost forgotten that she was still a virgin in the conventional sense.
"Now, let's get on with it," he said briskly. "Spread your legs! Experiment DV-100, Defloration of a Virgin, is about to begin."
Marcy whimpered as he drew the turgid cock down over her face, across her chin and neck, and onto her breasts. He let it linger there, rolling the massive pole over, under and around the showy mounds, setting her nipples on fire with the touch of his burning flesh.
"You have lovely breasts, X-999," he observed. "We shall extend our experiment to include fucking them." He pressed a hand to the outside curve of each lush globe, and squeezed them together around his mammoth shaft. Marcy thrilled to the feel of him ramming his prick between the sensitive inner slopes of her breasts.
