The tips of her nipples were being titillated by the same kind of sensual vibration that seemed to center at her breasts. Susi's toes squirmed as violent shudders of delight coursed along her nervously perspiring body. The tightly clinging channel of her cunt was on fret Susi seemed to tinge all over, and yet all she could do was moan and plead for Dr. Randolph's mercy. Why had she ever come here in the first place? Why? She would never, ever do such a thing again, if only she could get out of here alive and with her sanity too.
"Let's see how you like this one!" Adam said, smiling at his success and pushing another button which automatically canceled out the electronic message to the part of the machine which controlled the little rubber protrusions. They were replaced by the emergence of small suction cups which extended to the edges of Susi's inner walls, attaching themselves and beginning a gentle rotation and sucking where before there had been a tickling, teasing sensation.
"Oooh!" the huge unbending rubber phallus throbbed on, seeming to go deeper, but in reality expanding while her moist warm flesh clasped tightly around it. Susi felt her body slowly changing into a mass of nerve-tingling sensation. Her eyes were tightly shut now as she struggled against the rippling waves of unwanted pleasure that rushed through her helplessly trapped body. She fought against them with all her might, but the machine created more and more indecent desire within her. The very thought of her own helplessness, instead of infuriating her as before, began now to weaken and infiltrate her with a new awareness of herself. Was this what she had secretly wanted all along? Someone, something, that could give her pleasure and take none in return? Was this why she could never treat anyone who loved her with respect, for fear of giving up too much of herself. It occurred to the eighteen year old that there was nothing to lose here, no human being was touching her, despite the fact that the professor was obviously manipulating the sex-machine. An excited moan escaped her lips, betraying her sudden submission to the nefarious instrument.
My God, Susi thought, I love it! I love this Goddamned machine!
"Now you like it, yes?" Adam inquired, regarding the distinctly lascivious expression on his captive's features through the two-way mirror.
"Ooooh!" she groaned helplessly, all the while feeling her tightly swollen breasts bewitched by the soothing vibration at their nipples. It seemed the full rounded mounds of naked flesh would burst from the exquisite pleasure coursing through them.
Susi tried to arch upwards, flinging her long red hair from side to side as she felt all resistance fleeing her mind and body. Just as suddenly as the pleasure had come to her aroused young body, it was suddenly gone, as experimentally Adam Randolph withdrew the thick head of the cock from the raging heat of Susi's now-willing cunt.
"Oh no!" she gasped.
"No, what?"
"No! No I… I…"
"You want it to fuck you some more now, don't you?" he asked, unable to erase the self-satisfied tone of his voice. "Then say it, my dear. Say it loud and clear, and you shall get your wish. Maybe you were on the verge of cumming? Tell me what it was like the first time you came with a man. Tell me all about it!"
"Oh Christ, you sadistic bastard!" Susi writhed in frustration as all the vibrations of the innocent looking couch ceased. "I was fucking my uncle. My uncle's cock was fucking me hard. I wrapped my legs around his neck, he was holding onto my ass! And I came!"
"Yes?"
"Oh give it to me, give it to me! Give me the machine!" All resistance had drained from the eighteen year old's distorted mind.
"I still fuck him!" she said desperately, hoping that the machine would return to life faster if she gave more information. "I fuck him whenever I feel like it and I… make… him… lick… my… shoes!!"
The maddening but thoroughly desired probing of the artificial cock returned, spiraling its way up into her unresisting pussy, fucking upward with new girth, the sucking cups alternating with the little rubber points white the over-all vibration of the bed resumed.
"Oh God, it's good, go on, go on!" As best she could the young redhead bucked downward into the fucking machine and began to blurt out incoherently all the vile, filthy words she knew which was a considerable lot. "Oh, Christ! It's the best! The very best! Oh fuck me, machine! Fuck Susi good!" she blurted.
Adam Randolph looked out from the control room with lewd delight at the sight of the sweat-glistening body of the helplessly strapped-down waitress, his first subject at the lab. He could see the big white mechanical penis he had devised doing its upward skewering from beneath and below the redhead's widespread legs. He timed the thrusts to match the contortions of her face, carefully noting the exact speeds and strokes in his recorded notes. Back and forth, suction, ticklers, rotate, swell, double-time forward and backward flick. Dr. Adam Randolph's fingers flew on the control buttons as he began to invent new combinations of the lewd series of actions.
There in the room which the professor called his "lab" the girl could feel the sudden rising tide beginning deep in her quivering belly. It had been a long time coming, and now it was upon her. The perfect lover had found a way to give her the kind of pleasure she truly needed, a pleasure that would in no way commit her, a pleasure which would not be reciprocated. No horrid man would get anything from her this way. No, there was nothing given, everything taken! The very hopelessness of her position, and the debasing ravishment of her nakedly trembling body brought a promise of a new orgasm, a different orgasm. She sucked in her breath as she felt her insides erupting with pleasure as though she were a volcano, dormant for too many years, now suddenly brought to life after sporadic rumblings.
The eighteen year old waitress's tongue flicked out to lick at her parched lips now as the building pleasure suddenly burst forth and the cry of unfettered joy came from her throat. Her orgasm flooded in great rocking waves within her and the cuntal muscles that surrounded the gyrating fake penis rippled crazily along the artificial surface as her liquid passion seeped outward and her vaginal lips clasped tightly around its base. It was an indescribable sensation for the young girl who had thought until now that she knew everything there was to know about sex. Now she knew that that was far from the truth. Whole new vistas were opened up to her now that she understood something about her true relationship to the world, to men, to life.
"I love you, fucking machine!" she gasped. "Oh you lovely, lovely machine!" Tears of pure bliss fell from her usually mocking eyes. She felt a sincerity of feeling that touched hitherto hidden recesses of her heart. Obscenely the young girl wallowed and wriggled about on the bed until at last the last button was touched, the last panel light gone out. She lay feeling the beautiful throbbing of her own insides, the low hum of pleasure that still dwelled in her streaming cunt.
Her eyes fluttered open as Adam Randolph came into the room and stood watching her for a moment. If only he doesn't spoil it, the girl thought in a moment of panic.
She watched as the scientist reached into the front of his white coat, and brought out the thick raging shaft of his penis.
"Are you going to fuck me?" she asked, tremulously.
"I already have," Adam answered, his mind miles away. Why did he have to be thinking about Helen at a time like this? It was absolutely spoiling everything.
"No… no! It wasn't you! It was the machine!" Susi gasped, for she could still feel the residue of pleasure that it had given her.
Adam stood uncertainly, holding his nakedly pulsing penis in his hand.
"Can I ask you something?" Susi said at length.
"Yes, what?" Adam was already putting his dully throbbing cock away. It was no use fucking her now, his heart really wasn't in it.
