Mrs. Swenson came hurrying at Dr. Villiers' call. Her white uniform rustled crisply as she came into the room, her huge breasts bouncing slightly from walking so fast.
"You called me, Dr. Villiers?" she asked, ignoring the fact that they were all nude.
"Yes, my dear Mrs. Swenson," Dr. Villiers said. "There are four of us here, which would be fine for a game of bridge, but the game we have in mind requires mother player."
"Well, I'm not much for games, Doctor," the woman said, backing up a step or two.
"Take off your clothes, Mrs. Swenson!" Villiers said, his voice quiet but commanding.
"Now Dr. Villiers, remember my professional…"
"Get out of that uniform at once! Or shall I have young Kyle here rip it off?"
Kyle took a step toward the big woman, his delight at the proposed violence obvious. Mrs. Swenson took another step backward, then reached up and began unbuttoning her white uniform. In a minute she was standing before them clad only in a white cotton bra, white underpants, and white stockings.
Marcy looked at the mountainous breasts held under control by the utilitarian bra, at the rounded belly and broad hips, at the heavily fleshed pink thighs showing between the stocking tops and the panty legs, and at the rippling sinews of arm and shoulders. She wondered how it would feel to have sex with a woman built like a weight lifter. She had the distinct feeling it wouldn't be long before she found out.
"Well, shall we begin?" Dr. Villiers said, walking over to the Swedish woman and reaching behind her to unhook the bra and free the huge mountains of her breasts.
Mrs. Swenson watched with her mouth open in surprise while he attempted to encompass the enormous globes with his hands.
"Remarkable, quite remarkable," Dr. Villiers murmured, producing a tape measure and calipers from somewhere and beginning to take careful measurements of the tremendous mammaries. When he finished that, his hand moved into a more direct experiment. It slipped inside the white pants, pulling the crotch to the side so the three watching could see his fingers searching through the thick forest of wiry blonde hair to find the thick-lipped gash of her sex, and start exploring it.
"Remarkable, truly remarkable," Dr. Villiers repeated, as most of his hand disappeared into that massive sex canyon.
"Dr. Villiers, I am a respectable married woman, a professional nurse and physical therapist. Those are the services you pay me for and…" the words of protest trailed off and the woman's head lolled to one side, a strand of hair falling across her forehead. Before their eyes, the disapproving, uptight woman changed into a slack-jawed-sensualist.
Kyle grinned and moved to join Dr. Villiers in his assault on the female leviathan. Using both hands, Kyle lifted one of the Everest-sized breasts, and opening his mouth as wide as he could get it, managed to draw the colossal nipple into it.
"Well, what are you girls waiting for?" Dr. Villiers asked. "I would say there's enough here for all of us. Come, join the experiment."
"I thought you'd never ask!" Karla giggled, and moved quickly toward the three.
Slowly, in the almost trance-like state that seemed to come over her when she was near Dirk Villiers, Marcy also walked toward the group.
"Wow, would you look at that ass!" Karla was saying, going around behind the immobile nurse and pulling the white underpants down off a pair of buttocks so large that each might have made the stern of a fairly large ship. "I haven't seen so much white meat since I visited the white whale preserve."
Marcy squeezed between Kyle and Dr. Villiers, conscious of their firm flanks touching her soft hips, and even more conscious of the smell of sexual excitement Dr. Villiers' hand was stirring up in the swampy valley, between Mrs. Swenson's thighs. There was a strange acrid odor to her cunt that puzzled Marcy as she reached for the gigantic breast that Kyle wasn't working on.
"Well, X-999, showing a little initiative, are you?" Dr. Villiers said in an amused tone. "I like that in my experimental subjects." Withdrawing his hand from the marshy cunt of the moaning woman, he lifted it so they could all see how wet it was, clear up past his wrist.
"Very copious," he said, and lifted his hand higher to sniff at it and then taste it, a puzzled look on his face. "How strange. I wouldn't have believed it. No, not even allowing for that overly starched look and the hyper cleanliness of the woman. It's simply unbelievable. Here, smell this, X-999."
He shoved his wet hand under Marcy's nose. Dutifully, she sniffed and tasted and then looked up at him, her expression as disbelieving as his. "Disinfectant! She smells and tastes like a hospital!"
"So what did you expect?" Karla giggled. "She walks and talks like a hospital, so she's bound to smell like one. Let me see how she is back here." She dropped to her knees and her red head almost disappeared between the massive buttocks.
Mrs. Swenson let out a yelp of surprise as Karla's enterprising tongue tickled the brownish-pink anus, and then jabbed a little way inside. "Please – what are you people doing to me?"
"Experimenting, simply experimenting," Dr. Villiers said calmly. "I'm sure a dedicated person like you wouldn't object to donating your body to science after you were dead, so why should you object to doing the same while you're still alive?"
The huge woman shook as though with the palsy. "That girl – what is she – doing – to my – asshole?"
"She's merely helping you to a deeper understanding of your sexual potential," Dr. Villiers said.
Marcy was working the white pants down the tree trunk legs, exposing a forested area in which Robin Hood and all his merry men could have taken refuge. Dark blonde foliage spread lushly across the base of the woman's belly, ran down the insides of her thighs, and festooned lavishly over the bulging cunt mound.
"Isn't that something?" Marcy marveled, bending over to get a better look at the long, wide, red crevasse that split the mound from top to bottom. "I think I hear an echo."
"Don't be such a smart mouth!" Mrs. Swenson said. "Just because a lady is generously proportioned is no call to…"
"Hey, Doc, if we had a couple more men with good-sized cocks, and we could figure out a way to do it, I'll bet she could take us all inside her at once," Kyle said.
"We'll have to postpone that experiment until a later date," Dr. Villiers said. Using both hands, he spread the opening into Mrs. Swenson's vagina, and both Marcy and Kyle got down on their knees to peer into its pink and purple depths.
"Wow!" Kyle said. "I think I see Stanley in there looking for Livingstone!"
Marcy couldn't think of anything to say. She was overwhelmed by the soap-and-water, disinfectant smell that rose on a wave of heat from the woman's cunt. She reached between her own legs and ran her fingers into her own wet depths, thinking that it would take five or six slits the size of hers to fit into the Grand Canyon she was staring at.
"Why don't you taste it, my dear?" Dr. Villiers said, peeling back one of the hair-covered flaps so it almost touched Marcy's lips.
"Why don't we both taste it?" Kyle said, and without waiting for permission, began to lap at the cunt lip opposite the one Marcy's lips were daintily touching.
Marcy whimpered as she felt Kyle's fingers join her own in her squishy channel. Tentacles of lust curled through every inch of her body, and she hungered for more sex, and more and more. She felt a craving for multiple experiences, she wanted to share her great billowing lust with all these people at once. She let the feeling flow through her until she could bear it no longer, and then she reached out a hand and found the giant phallus that reared from between Dr. Villiers thighs. Her fingers fluttered over it, searching and caressing, before gripping it near the massive head. The other hand located the smaller monster that perpetually rose from Kyle's groin, and then she began to massage both throbbing organs, while her tongue licked and slurped avidly at Mrs. Swenson's steaming gash.
With a sigh like a dying hippo, Mrs. Swenson sank down on her side and the four experimenters swarmed over her like wolves closing in for the kill. And there was plenty of body to swarm over. Dr. Villiers positioned himself over the big woman's face, squatting on her upper chest with his buttocks resting against the ramparts of her breasts. When he was settled, he began to acquaint Mrs. Swenson with his cock. He rolled it over her mouth, rubbed it across her cheeks, poked its big round cap at her nostrils, and then returned to butt it against her closed lips.
Mrs. Swenson made a low, groaning sound as the insistent ramrod flattened her lips against her teeth, increasing its pressure until she was forced to take it in her mouth.
Marcy swung herself around so her, back was to Dr. Villiers, and by reaching around him she could again take hold of his stately cock, even while it shoved in and out of the whimpering Swede's mouth. By leaning forward, Marcy figured she could also reach the patch of wet hair at the base of the woman's belly. She could reach it, but something else had beat her to it. Just inches from her nose, Kyle's prick was sinking into Mrs. Swenson to the hilt.
"Oh well, the more the merrier," she said philosophically, and began to lick up and down the plunging shaft as well as the mushy flesh around it.
Having lost her place between the monstrous buttocks when Mrs. Swenson flopped onto her back, Karla was now scrambling over the lust-drenched pile looking for a place to insert herself. Spotting Marcy's spread legs and the wide-open slit between them, she wormed her way in under Marcy's legs until her tongue made contact with the burning crevice. Just at that moment, Dr. Villiers swung around, and with his prick still buried in Mrs. Swenson's puffed-out cheeks, he got both hands under Marcy and lifted her. That enabled Karla to stretch out between Marcy and the Swedish woman, and push her red-tufted pussy into the triangle already formed by Mrs. Swenson's twat, Kyle's prick, and Marcy's mouth. By also tilting her buttocks upward, Dr. Villiers was able to bring his mouth close to them, and Marcy was unexpectedly treated to the extraordinary experience of having the doctor's long, red tongue inserted in her anus, where it pushed past the sphincter and began to delve lustfully into her innards.
Marcy was presented with an even more extraordinary configuration before her mouth. Never had so recent a virgin been presented with such a feast of lust. Offered for her delight were a mammoth juicy cunt, a big cock fucking joyously into it, and a red-tufted miniature of the first pussy trying to join the action by rubbing against the thrusting lance.
Breath hissing through her teeth in her frantic excitement, Marcy dove into the middle of all the lusting flesh, driven almost mad by the jolts of pleasure from Karla's tongue in her hot box and Dr. Villiers tongue twisting in and out of her rosy little asshole.
This was an absolutely mad situation, she knew. Marcy McCall couldn't be doing this! Marcy McCall wouldn't dream of touching her tongue to wet pubic hair and slippery, hairy testicles, nor would she stab it into the steamy swamp that was the canyon between Mrs. Swenson's thighs. And she most certainly would not suck with such deep pleasure another girl's throbbing clit. What would her friends back in Plainview think if they could see her now? What would her more sophisticated friends in San Francisco think, for that matter? More to the point, what would Jimmy think if he knew his big sister was just part of a pile of bodies doing every dirty thing they could think of to each other? And – oh God! – what would poor Fred think? Funny, she hadn't thought about Fred since she entered this place. What would Fred think if he could see his fiance now? His Ice Box Cookie, his Snow Maiden? How could he reconcile her with what she had become – a sex machine to be used for sucking cocks, licking cunts, and receiving pricks in any or all orifices of her body.
She knew she should be blushing with shame at such thoughts, but she wasn't. The only one that really shook her was what would Jimmy think. What if slender, sensitive, sandy-haired Jimmy should walk in and see her as part of a pile of fucking, sucking, writhing, groaning, grunting, lust-driven flesh, instead of as a dignified, individual human being?
She bit down harder on Karla's clit, and drove her tongue deeper into the pungent river of cunt juice that was beginning to flow out around Kyle's thrusting manhood. What would Jimmy do? Would he scream in horror and run away, never to see or speak to his sister again? Or would he – she shivered violently at the thought – would he just tear off his clothes and leap into the heap? Would he seek her out and stick his precious young prick into whatever opening was available?
The dark excitement of that thought drove Marcy to fresh efforts. She twirled her tongue around Kyle's man flesh, and rode it inside Mrs. Swenson's pussy to lick the inner walls. Then she went back to Karla's knob of a clit, and chewed and sucked it.
"Do that some more," Karla whimpered. Marcy did it some more. She caught the clit between her lips and rolled it around and around. She opened her mouth wide, and sank her tongue into the girl until her teeth scraped the outer folds of her cunt. Female juice filled her mouth, filled her throat, and her whole body vibrated from the hot thrill of it.
Suddenly there was a loud grunt from Kyle, and he creamed into Mrs. Swenson in another of his torrents. The force of it shook the whole pile of human flesh. And as the spicy wetness overflowed the great cavern, Karla followed her brother's example and climaxed, even as she rammed her tongue deep into Marcy and brought the girl upward into a flaming paradise intensified by Dr. Villiers thrusting into her nether channel. Next in the chain reaction was Dr. Villiers himself, and he gave a low shout of triumph as his throbbing cock spilled into Mrs. Swenson's mouth, and then all over her face. The Swedish wo-mouth, and then all over her face. The Swedish woman's climax followed almost immediately, and it was a thing of wonder to see. She grunted like a gaffed whale, thumped her massive buttocks on the quaked and shook. When she was finally still, they all lay quiet for a few minutes, their heavy breathing a chorus of satisfaction.
"That was very nice, X-999," Dr. Villiers said finally. "You have one of the most delectable asses it has ever been my pleasure to explore."
"Thank you," Marcy said.
"It all came off rather well, I thought," Dr. Villiers continued, adjusting his glasses and getting out his notebook.
"Would you call that an orgy?" Marcy asked.
"Good Lord, no!" Dr. Villiers sounded shocked. "An orgy, my dear, is when people get together and drink and eat, sing and dance, and then take off their clothes and indulge in various obscene acts."
"But we…" Marcy began.
"Now we didn't have anything to drink or eat, did we, my dear?" Dr. Villiers said, jotting down some notes in his book.
"No, we didn't, and I'm getting hungry."
"And I don't remember any singing," he said.
"No, but…"
"Surely no one was dancing?"
"No, but we did do an awful lot of obscene things," Marcy insisted.
"Obscene? What a thing to say!" Dr. Villiers looked around at the Karlows, who were languidly licking other people's jism off each other's thighs and genitals, preparatory to building up another head of steam. "Did either of you see anyone do anything obscene?"
"Nary a one, Doc," Karla said, and returned to probing the tiny slit in the end of her brother's prick with her tongue.
"Of course we didn't see anything like that," Kyle said. "We know you don't permit such behavior around here."
"Then what was it we did?" Marcy asked.
"We performed a series of scientific experiments, my dear," Dr. Villiers said, vigorously dotting an in his book for emphasis.
"I'm not sure I understand the difference," Marcy said.
"Well, my dear, when people fuck, eat cunts, and suck cocks at an orgy, they do it for fun. But when we do it here in the laboratory, it's research for the advancement of science. That makes all the difference in the world."
Mrs. Swenson snorted. "Bullshit! What we did was dirty as hell – dirtier even than a Swedish movie, and I loved every minute of it! Let's do it all over again! Come on, everybody fuck me!"
She spread her meaty thighs and showed them the yawning chasm between. "Come on, any two of you! Any three! All of you at once!"
"My, my," Dr. Villiers said, making another note in his book, "beneath that starched exterior we seem to have uncovered a volcano of lust."
His black eyes surveyed Mrs. Swenson's prodigious offering dispassionately, considering it with his usual objectivity. "No – no, I think not. You were the center of our last endeavor, my dear. This time, since our investigations are basically aimed at the progressive sexuality of a recent virgin, X-999 shall merit our full attention."
Marcy yawned. "Don't I ever get to eat or sleep?"
Dr. Villiers looked at his watch. "You were fed a big breakfast and instructed to eat it all. The animals will not be fed again until five, but in the meantime," he smiled down at her, "we'll certainly find something to put in your mouth that will make you forget all about food."
Marcy sighed resignedly. "All right. What do I do this time?"
"Assume a supine position, if you will, and…"
She started to lie down, but he stopped her. "No, on second thought, I shall lie down first and then I want you to position yourself facing my feet, with your cunt poised over my cock."
"Yea, Dr. Villiers," Marcy said, with her usual docile acceptance of his orders. She turned and faced his feet, and then lowered herself until the damp pubic hair was just touching the tip of his remarkable shaft.
"Yes, yes, that's it. Now just hold that position for a moment, will you please, my dear?" Dr. Villiers said, drawing a little diagram in his black notebook. "And now Kyle…"
"Yes, sir!" Kyle said eagerly, untangling himself from his sister. "Anything you say, Sir!"
"How would you like to insert your cock into X-999's vagina from the front, while I do the same from beneath her?"
"Wow, groovy, man, groovy!" Kyle enthused. "The very thought of feeling my insignificant prick pressed against your masterful phallus, of rubbing my sensitive flesh against yours while we both fuck X-999, is pure heaven."
"Hmmmm," Dr. Villiers said, making another note. "Previous indications of homosexual tendencies verified." He looked up at Marcy. "And you, my dear, do you think you can accommodate this massive insertion of male flesh I have outlined?"
Marcy's head was spinning, and her knees were weak. During the past two days of almost continual sex, she had fantasized about such a penetration, but now that she was faced with the actuality, she was stunned. "I'll – yes, I'll take it, no matter what."
"Excellent," Dr. Villiers said, making another mark in his book, and causing Marcy to wonder if he were chalking up brownie points for her.
"And what about us?" Mrs. Swenson asked. "That little sexpot gets all the cock and we get nothing?"
"X-999 'getting all the cock' is precisely the point of this experiment, Mrs. Swenson, so protesting the fact is pointless. However, there will be something for you and S-125 to do while S-124 and I are sheathing our cocks in the same furrow."
Excitedly, Kyle knelt between the other man's outstretched legs, his prick on a level with Marcy's open cunt. He stared down at the massive shaft poking at her entrance with undisguised longing. "If only I could have that perfect pylon thrust up to the balls in me! How I'd love to be flat on my belly, squirming in joy and pain as you pinned me to the floor and slammed into me until my soul was spaced out on cock!"
"Later, perhaps," Dr. Villiers said, "but I don't promise any soul spacing, whatever that may mean."
"Could we please hurry up and get started?" Marcy asked, rubbing her wet pubes over the rearing head of Villiers' shaft, feeling the controlled power of it and wanting it desperately.
"Very well, my dear, if you will lower yourself slowly until you are partially penetrated. Then Kyle, you will please insert your member between the upper portion of the coital canal…"
"They're going to split her right up the middle," Karla said, dropping to her hands and knees to get a better view of the two engorged cocks trying to enter Marcy at once.
"They sure are," Mrs. Swenson agreed. "They shouldn't try that with a punk kid like that." She had dropped to her hands and knees too, and was staring at the fantastic tableau. "Why don't you try it with me, Doctor? I could hold you both with room to spare."
"If you can do it, so can I," Marcy said. "Cunts are very stretchable, and I want them both in me at once."
"Well, I admire your spirit," Mrs. Swenson said, "but it looks to me like you're going to get more pain out of it than pleasure."
"Wouldn't it help if I warmed all three of you up first with my mouth?" Karla asked. "If I got Marcy good and wet, you guys might go in easier."
"I'm already as wet as I can get," Marcy said. "I'm dripping with three different brands of sex juice plus my own."
"Excellent spirit," Dr. Villiers noted in his little black book. "Test subject shows fine morale. Let us proceed."
"We are proceeding," Marcy said, lowering herself a bit more, until she could feel the gigantic cock pushing her open and expanding the inner labia. Then she held her position, slightly delirious with anticipation as Kyle approached her from the front. She wanted them both, and was determined to hold them if it killed her.
"Now, my boy – now!" Dr. Villiers ordered.
"Okay, here I come!"
Marcy felt Kyle's prick against her outer lips. There wasn't much room left there or inside. She could feel him shoving where there was no opening and being rejected.
"Closer to me, lad," Dr. Villiers instructed. "You've got to slide your cock along the bottom of mine, touching all the way, and enter that little stretched place beneath my glans."
"Yes, yes, glide all the way along yours… ahhhh!" Kyle looked as though he were about to faint with excitement as he pressed his manhood tight against Villiers' and shoved it along the underside, rubbing the sensitive head on the hard rod and whimpering like a girl. "Ohhhh… ahhhhh… so good, so could cum right now just from touching you this way."
"Don't you dare, you little beast!" Dr. Villiers said. "You'll ruin the experiment if you do. This isn't for your benefit, you know. This is experiment No. 55-00-9, Penetration of Virginal Cunt by Two Cocks. Do it right, dammit!"
"Oh God… that hard, hot flesh… the thickness… the monstrous, dangling balls… I can't stand it… I just can't!"
"Shut up, you silly fool," Mrs. Swenson said. "Shut up and do what the doctor tells you!"
Kyle had managed to work the nub of his organ past the outermost gates and was pushing into Marcy, spreading her just a little more. But he was still whimpering about his imminent explosion.
"If you cum now, you're going to ruin it all," his sister warned.
"I know, but it's so goooood. If you could just feel how how it is… how thick and…"
"Stop that! You're just getting yourself all overheated!" Karla said, and raised up until she could nip her brother at the base of his prick.
"Ow!" Kyle yelled, and his constantly hard shaft wilted a little. Quickly Marcy reached down and stuffed the sagging joint into the small opening to the side of Dr. Villiers' massiveness.
Kyle continued to howl, but it was with pleasure now as Dr. Villiers reared upward and sank all the way into Marcy, carrying Kyle's rehardening organ with him.
Marcy was sobbing now with the pleasure and the pain. She was being stretched beyond her wildest imaginings, as man meat filled every cranny of her cunt, bulging the resilient walls outward to make more room.
"They're in me – oh God, they're both in me!" Marcy squealed.
"I'd never have believed it," Karla said, examining the joining from around her brother's waist. "That tiny little cunt holding all that hard cock!"
"It's a miracle," Mrs. Swenson said, sticking her head around from the other side to get a close-up view of the coupling. "Look how the lips are pulled almost flat."
"I think I'm going to faint," Marcy said suddenly. "My head is going round and round and I feel so weak and funny."
"Don't let it concern you, my dear," Dr. Villiers said. "You'll be held up by our cocks even if you do pass out, so don't worry, the experiment will go right on."
