A week passed during which nothing happened at the institution. Then one day Matilda entered Lavinia’s room with all her gear in a suitcase.
“Matilda! How are you? What is that you have there?”
“My belongings, of course,” Matilda laughed. “The doctor told me the time had come to move in with you permanently.”
The girls embraced and laughed and went out to the cafeteria for lunch. They hadn’t been to classes since their escape and return to the institution, and they were glad to be free of the routine.
When they returned to the room, they found a tape recorder had been installed under the bed, with the microphone on a hook on the bedstand.
“Well, well, it looks like dream testing is in full swing at last!” Lavinia exclaimed. “Actually, I hadn’t expected it to happen this soon. I have to admit it makes me feel strange. I’ve had some pretty weird dreams, and I don’t know what it would be like to act them out in reality.”
“You’ll find out,” Matilda said.
“Well, before it begins, let’s make our minds up to enjoy ourselves as much as possible in conventional methods, before we’re embroiled in our dreams. Chances are very good that we won’t be the same after this dream testing thing.”
“How conventional is my cunt?” Matilda said saucily as she lay back on the bed and removed her one-piece garment. They had stopped off at the bathing pool after lunch, and their bodies were still fresh and damp from the cool water.
“You really have a nice figure,” Lavinia said. “I think it’s beautiful. I’ve thought so since that first day when Mrs. Hatchett took me to the pool, and you were there swimming.”
“I’d like to be ravaged, right now,” Matilda said huskily. “While I’m lying here, without having to do a thing in reciprocation.”
Lavinia, naked also, went to the bed and sat down beside Matilda. She placed the palm of her hand on her flat abdomen. Then she leaned forward and carefully touched the tip of her tongue to the soft nipples of Matilda’s breasts. The nipples became hard and erect immediately.
“Do you want to make love?” Matilda said. “The doctor is right. You shouldn’t if you don’t want to.”
“I always want to make love to you, Matilda,” Lavinia said. “Regardless of how I feel. You feel like being ravaged, and I feel like ravaging you. It’s perfect this time. Just be quiet now and let me take you.”
Matilda closed her eyes and reclined on the pillow. Her long, smooth thighs trembled a little as Lavinia touched them on their soft inner sides with her fingertips. Their lips touched, lightly at first, then more ardently, and Lavinia pushed her wet tongue deep into Matilda’s mouth. Matilda groaned and sucked at the tongue, pulling it down almost into her throat. Lavinia’s hand cupped the thickly haired mound between Matilda’s legs, and she felt the thin lips of the pink labia plop open delicately. Her finger eased them even wider apart and settled on the cool pink knot of her hard clitoris. Matilda moved her legs a little and moaned again. Lavinia began to probe deeply into the well of Matilda’s cunt with her forefinger, working the hot pussy into a foamy lather. Matilda arched her back slightly and thrust her hips up. Then Lavinia took the full taut globe of a breast into her mouth and sucked until the ripe meaty fruit of the tit filled her mouth, and Matilda was squealing with delight. Her vaginal muscles closed tightly around Lavinia’s furious finger.
“Oh, I don’t want to be ravaged anymore, I don’t want to just lie here!” Matilda cried. “I want you, Lavinia. I want to make love with you. I want to feel your mouth on my cunt, your tongue, your hands, and I want to taste that softness between your legs. I want to lick you and suck you until you come!”
Quickly, Lavinia swiveled around and buried her face in Matilda’s fuming crotch. Matilda cried out and tightened her thighs around Lavinia.
Lavinia parted the gauzy wet labia with her tongue and thrust into the tightening well. She clutched Matilda’s soft buttocks and with her fingertip found the round indentation of the anus. Matilda penetrated her almost simultaneously, and her mouth was a warm glow between Lavinia’s legs. The two girls were rocked into a dreamy swoon that lasted until they were asleep.
The next morning - and for many mornings after that - they woke and repeated into the recorder all the dreams they could remember from the night before. The first few mornings were like a slightly embarrassing game, serving to assist them in combating boredom. But eventually reciting their dreams became a commonplace thing, part of each morning’s ritual, and they soon forgot the original significance of this new practice.
After living in the same room for some weeks, the doctor suddenly ordered them to remove themselves to a new room in another wing of the building.
Mrs. Hatchett led the girls across the grounds, carrying their belongings into the new wing. The hallway was filled with numerous aides and young doctors and nurses scurrying here and there, peering into rooms through the small special mirrors in the doors. Matilda and Lavinia did not have a chance to take a peek inside for themselves, but they were extremely curious, and Mrs. Hatchett had to call them away from the closed doors many times, urging them on down the hallway to their new room.
The new room was much larger than their original compartment, complete with two full beds, carpet, and drapes. A record player and a small bookcase were near a window facing the grounds.
“Well!” Lavinia remarked. “If this is dream testing, it’s for me. This is the most comfortable place by far that we’ve ever had in this place.”
“It certainly is,” Matilda said playfully, bouncing on the bed. “Won’t we have fun with the doctor when he comes in to play with us? Can you imagine what a party the three of us can have on these beds? They’re simply huge!”
“Yes, it’s wonderful!” Lavinia said.
And then the lights went out.
They heard a key in the door tumble the lock.
“What’s this?” Matilda started.
A voice, metallic and reedy, yet obviously the doctor’s, came over the intercom system.
“Girls, we are beginning your first dream testing session. It’s up to you to see that all goes well. I want you to take the two capsules you will find on the nightstand and swallow them. Then lie down on the bed and wait. In about thirty minutes, representations of many of your dream desires will appear to you, and we can begin to find out which are suitable in reality and which are not. Are you ready?”
“I’m frightened, a little,” Matilda said.
“There’s nothing to be afraid of,” the doctor soothed them. “Just take the capsules so we can proceed.”
Lavinia went to the nightstand and found the two capsules. She handed one to Matilda, who was trembling slightly, and then popped hers into her mouth and swallowed it.
Together, holding hands like children, they stretched out on the bed and waited in the dim light.
Soon, Lavinia felt giddy, almost drunk, but there was no unpleasant physical feeling involved in the sensation. The edges of her vision blurred, and she breathed heavily. She could hear Matilda’s breath coming as ragged as her own. The walls of the room were wavering, watery. Was that a panel sliding back, revealing a dim square of light and a figure? Yes, it was, or was it her imagination, or the drug?”
“Do you see him?” Matilda whispered nervously.
“Yes, I do,” Lavinia said.
The man was huge. And naked. He was easily over six feet tall, and in spite of the darkness in the room, he was darker, his skin shimmering black beneath the body oils with which he had been rubbed. Across his cheeks were three bright crimson and yellow slashes of paint. His large white eyes glared at them. As he drew near the bed, they saw how incredibly beautiful he was. His velvety muscles rippled under his taut, shining black skin. He stood at the foot of the bed and looked at their trembling bodies. His cock stood upright, stiff, and throbbing with his heartbeats. His nuts were smooth and dark as eggplants. The glistening knob of his slick glans was on a level with his navel. Lavinia noted, almost idly, that the circumference of this supernormal organ was approximately that of her own wrist.
“He’s beautiful!” Matilda gasped.
The man reached down casually and gripped Matilda’s ankle, pulling her down until her legs were off the bed and her round, trim buttocks rested at the edge. He held her ankle and pulled her leg up and out to the side as far as possible, revealing the dimpled cleft of her damp pussy, and with his left forefinger, he began to probe that depth, sinking his finger in as deep as it would go, wriggling it, moving it in and out, until Matilda whimpered and bucked her hips in delightful anticipation of the promised release.
The man sank to his knees and gripped Matilda’s other leg at the underside of her knee, and pushed them back, making her buttocks and cunt most formidable. Lavinia watched with fascination. He chuckled deep in his throat and slowly lowered his face, his thick pink tongue extended, parting her labia, sucking at the dripping vagina and her swollen clitoris until she knifed her fingers into the bedding and heaved her hips forward to facilitate the man’s entry. He cupped her buttocks in his hands, as he would have held a drinking gourd, while she held her legs out of the way, his mouth surrounding her entire genital area, as he sucked and slurped at the juicy cunt. Matilda was trembling violently. Then she began to come. Her whole body quivered and spasmed as he drank voraciously from her spewing vessel, lapping greedily at the thick outer lips, sucking on her clitoris, until she moaned and thrashed with the exaggerated sensations.
He rose and went to the side of the bed, wound his fingers in Matilda’s long hair, and dragged her back to her original position, then threw one knee across and came to rest between the women.
He placed his hand at the back of Matilda’s neck and pushed her face down to his erect cock, almost as long as Matilda’s forearm from elbow to wrist. The heavy yellowish glans was wet with a drop of white lubricant which oozed thickly from it, dripping over the shaft like ice cream melting and streaming down the sides of a cone.
Matilda grasped the cock with both hands at the bottom, next to the enormous smooth nuts, and took the glans into her mouth. It was so large she felt as if she were trying to swallow whole a small crabapple. The sides of her cheeks and her lips were distended with the effort. She sucked down on the heavy joint until it struck the back of her throat, then withdrew slowly, licking and savoring.
Reaching behind him, the man took Lavinia by her neck and pushed her down between his legs, settling onto his back as he did and instructing them for the first time vocally since his magical entrance.
“Get my nuts into your mouth,” he said.
Lavinia, on her knees now between the man’s legs, watched as he lifted them to make available his taut scrotum and the round, tight asshole beneath them. Matilda lay with her luscious breasts flattened against the man’s abdomen, clutching his cock, sucking it avidly, her eyes closed and a low crooning noise deep in her throat. She appeared to be in ecstasy. The black man had his face buried in the creamy white mounds of her buttocks, making loud slurping noises.
Lavinia began to lick a slow, neat circle around the man’s anus. Then she made her tongue stiff and thrust it into his anus as far as it would go, fitting her lips around that small hole and sucking the tender inner lining out a little so she could massage it with her tongue. He began to pant. She lifted the huge sack of his nuts and got them slowly into her mouth, careful not to touch them with her teeth. They filled her mouth near bursting, and she savored them, sucking lightly, humming, and groaning to send the vibrations up his spine. A few inches away, Matilda’s face was bright with an inner light, as she ate the gargantuan cock. She saw Matilda’s head jerk and her throat swallow several times, convulsively, and the thick, pasty come drool from the corners of her lips. Rather than choke, she pulled away for a moment to catch her breath, and at that instant, the black man’s ministrations at her own cunt and asshole broke her, and she began to come in long, quivering jerks that spasmed through her body. Taking advantage of this, Lavinia began to lick the black prick, lapping at the root and covering it with her tongue until she had ascended and slipped the heavy glans into her mouth. It was sweet and salty at the same time. She sucked and ravaged the member with her tongue. Then she felt his hands under her arms pulling her up, over him, her legs thrashing as the butt of the sweating prick rammed between her legs, missed once, then made contact with the soft yawn of her wet cunt. It plunged home with a grunt and shove which, for a moment, felt as if it might split her in two, but the short pain transformed into an immense pleasure, as he stroked into her again, and she realized that she was riding the largest cock she had ever seen. She threw her head back and began to laugh ecstatically, feeling the great strength of the man drive into her again and again. She came almost immediately, but he did not stop. She was filled up with his cock, as if her skin was merely a sheath for that tremendous shaft. She felt suddenly Matilda’s arms around her neck and her sweet mouth against her shoulders, and then her mouth. Matilda’s tongue licked her palate and pushed for the back of her throat. Then the black man was coming, and it was like a molten fountain erupting inside her. Her head was swirling. She gasped and lost consciousness.
When Lavinia awoke a few seconds later, she was lying on the bed next to Matilda. The black man stood beside the bed, fumbling with his prick. Lavinia saw that he was coating it with a heavy layer of gelatinous substance. It was still erect and as hard as stone. He came around the bed and indicated with a jerk of his thumb that he wanted Lavinia to get onto her hands and knees. She did as she was directed.
“Matilda, you get on your back between her legs. Use your mouth. On both of us.”
Matilda eased herself between Lavinia’s legs and lifted her face until her mouth pressed against Lavinia’s inflamed cunt.
“Part her cheeks for me,” the man said.
Matilda’s soft hands touched the round, full cheeks of Lavinia’s ass, parting them, at the same time finding Lavinia’s damp cunt with her mouth, sucking it, her tongue reaching up inside the girl like short, sharp jolts of electricity. The man placed one hand against the small of Lavinia’s back and with the other, he held firmly his thick cock, easing it into the lubricated eye of Lavinia’s ass. She groaned and buckled as the hard black prick sank in, inch by inch, until she felt as if he would split her in half with the tremendous organ. But the pain began a slow transformation, gradually passing from the unpleasant realm into one of delicious sensation. She was caught up between the penetration and the hot swift licks Matilda applied to her crotch. As they copulated, Matilda switched rapidly, first from Lavinia’s pussy to the dangling hard nuts to the greasy shaft of the cock, and then back to Lavinia again. Lavinia felt the man’s hot breath scalding over her shoulders, and his warm hands holding her limp form in position as he fucked her in her asshole. She was delirious with the soaring sensations, and found herself coming in long, warm streams, just as the black man erupted inside her, his hot come like a sudden wash of thick paste. Matilda sucked and lapped at the twin flows greedily, lost in her own fantasies.
When the girls awoke, the man was gone and the room was dark.
The girls were brought meals by Mrs. Hatchett, who spoke little, inquiring only after their immediate health, and offering to bring them anything they might want for comfort. There was nothing, the girls told her, so hypnotized were they by the reality of having their fantasies acted out, and so caught up in the anticipation of what the next trip might bring them. In the middle of the next day, they found out.
They had finished eating, and no sooner had Mrs. Hatchett removed the trays than the door opened and another person entered. Unlike the black man, this woman was vaguely familiar to both Lavinia and Matilda, who had seen her once or twice on the grounds and in the cafeteria.
She was strikingly beautiful. Tall, slim, voluptuously curved, her thick, lank red hair tumbled over her naked white shoulders down to the leather-covered swell of her marvelous, girlish ass. Her eyes were cat green, and as she stood in the doorway, hands on arrogant hips, staring at them, light glinting on the rowels of her silver spurs, twinkling on the hard sheen of her tight black leather pants, they felt their blood begin to simmer at the sight of this lovely creature. But what secret fantasy, indeed, was she here to make reality for them? In her right hand, casually dangling, was a long, coiled, braided leather whip. From the waist up, the Amazonian redhead was nude, and her large breasts and upper body had been oiled to a lustrous sheen. On her sculptured face was a leering, promisingly malevolent smile.
“Hello, darlings,” she whispered.
Lavinia felt a thrill in her loins, and felt also the sudden tenseness that settled into Matilda.
“This is one fantasy,” Matilda whispered, “that is fine as a fantasy, but in reality, something else altogether. If you don’t mind, I’ll just excuse myself from this one.”
Halfway to the door, clearly intending to slip past the ominous redhead, Matilda was frozen by the glare in the woman’s eyes. Her back stiffened, and the muscles in her smooth, pink buttocks grew tense. The redhead chuckled, a low, furry sound deep in her throat, and playfully stepped forward, touching Matilda’s flat abdomen with the cold coils of the whip. Matilda shivered. With the flat of her feet, the redhead kicked the door to and stepped forward, allowing the whip to uncoil on the floor. Then she reached around Matilda, caught the loose end of the whip, held it like a strap against Matilda’s buttocks, and pulled her forward until their thighs met. The hard nipples of their breasts affirmed the jutting crux of their sexes. Matilda whimpered.
“What, what are you going to do?”
“What I intend to do is unimportant,” the redhead said, “it’s what you are going to do for me that matters. Now, kneel!”
Matilda dropped to her knees. Her face was on a level with the hard leather-covered crotch.
“Undo my laces,” the redhead said. And then, glancing at Lavinia, she hissed, “Get over here!”
“Listen, I don’t think this... “ Lavinia began, but was interrupted as the long whip hissed through the air and cracked like a pistol shot just inches from her right breast.
“Move!” the redhead snapped.
Lavinia rose from the bed and came to stand beside Matilda. Her hands were trembling, and her body was bathed in nervous perspiration.
“What do you want us to do?” she asked.
“Get down on your knees, behind me,” she said.
Lavinia went behind the arrogant woman and knelt down. Her face was inches from the hard, sharply curved swells of the woman’s pronounced buttocks. As Matilda finished unlacing the front of the leather pants, the redhead hooked her thumbs in the waistband and pulled them down. Matilda helped her out of them.
“Now, if you want to get through this little experiment without tasting my lash,” the redhead smiled, “Just do as you’re told.”
Matilda’s face was pale.
Lavinia felt weak.
“I’ve got two holes down there,” the redhead said matter-of-factly. “Now put those pink tongues to work and see how wet you can make them!”
Saying this, she grabbed Matilda’s hair and jerked her face forward, at the same time thrusting her hips out and spreading her legs. Matilda’s mouth was forced against the flaming red pubic mound.
“Start sucking!” she said. “And you back there, get busy. My asshole’s hungry for your tongue!”
Lavinia carefully parted the buttocks and found the round, dark anus. It was slightly puckered, but quite clean. She placed her mouth around the tight little hole and began to work it open with the tip of her tongue. She could feel the redhead stiffening under the receipt of this pleasure. She could hear the subdued sucking noises Matilda made as she went greedily now after the scarlet pussy, sucking the labia into her mouth, lapping the hard, floating clitoris with long, thick swipes of her tongue.
When the girls had delivered a fine massage to the redhead’s privates, the woman pushed them away and walked to the bed, where she sat down and uncoiled the length of the whip.
“I’ve changed my mind,” she laughed. “It will please me greatly to give you a taste of this splendid whip. I won’t tear your skin, if you’re good little girls. I’ll just make it sting a little. Now get down on your hands and knees, bottoms facing me.”
They did as they were directed. The whip sang through the air like an angry serpent, and it was Matilda who winced and cried out, as the braided tip snapped against her right cheek.
Then the whip hissed out again and Lavinia felt the sharp pain, directly in the separation of her cheeks. It stung worse than a dozen simultaneous hornet bites. She bit her lower lip and shivered. Twice more the whip fell, and twice more sharp cries filled the room. They were waiting for the third attack when the redhead got up off the bed and came over to where the girls were still kneeling.
“Lavinia,” she whispered. “Your friend’s bottom is all red and welted. I think you should kiss it and lick it for her.”
Lavinia turned and found the poor, mistreated flesh of Matilda’s ass near her face. Her cheeks were tear-streaked, and she still whimpered slightly from pain. Three large, ugly welts marred the perfect beauty of Matilda’s bottom, and here Lavinia nuzzled, gently sucking and licking the wounds. After a few seconds, it was Matilda’s turn. Lavinia enjoyed the cool, soothing caress of Matilda’s lips and tongue.
“Now get onto the bed, on your stomachs,” the woman instructed.
As the girls rose to go to the bed, they saw their tormentor strapping a large, hard rubber dildo around her waist, arranging the instrument with a series of complicated straps, so it thrust out in a very natural position from the clump of red hair at her crotch.
The girls stretched out on the bed, thankful that at least for the time being they were to be spared the whip. The redhead climbed onto the bed and positioned herself between Matilda’s pale thighs, the shaft of the hard black dildo nudging at the dampness of the girl’s cunt.
“Hold it in place for me until I get it in her,” the redhead said coarsely.
Lavinia held the dildo with her fingers while the redhead wedged the blunt end between the fine lips of Matilda’s cunt, then she worked it in slowly, easing forward until her thighs were directly against Matilda’s buttocks, and the rubber cock was submerged to the hilt in the moist pocket of her sex. Matilda moaned and wriggled on the shaft, aroused by the depth of the penetration and by the enormous circumference of the tool.
“You do the work, baby,” the redhead said coarsely. “And don’t stop until you come.”
Matilda began to push herself onto the cock, easing off, pushing on again, while the redhead covered her back and neck with passionate kisses. It took a very short time for her to begin quivering and jerking in the throes of her orgasm. Immediately, the redhead withdrew the cock and turned to face Lavinia.
“Suck it!” she said.
Lavinia took the wet, dripping rubber cock into her mouth and sucked as if it were indeed the living member of a masculine lover. When she had licked it clean of Matilda’s moistness, the redhead pushed her roughly down onto her back and, climbing on top of her, drove the dildo into Lavinia’s cunt with a swift thrust of her hips. Lavinia gasped and, automatically, her legs flew up and embraced the redhead. She threw her arms around the woman’s shoulders. Their lips met. Lavinia felt the tool driving into her, again and again, deeper and deeper. Occasionally, the redhead gripped the shaft in one hand and swirled it sensually in the tight clutching lining of Lavinia’s box. Lavinia sucked blood bruises on the woman’s neck and breasts as the tool carried her over the brink into the depths of a tremendous orgasm that showered her with hot, fiery sparks. She barely remembered seeing the woman remove the instrument and bury her face between Lavinia’s arched thighs. It was marvelous. The dildo left her in the middle of a potent orgasm, and before the warm waves subsided, it was replaced by the redhead’s talented mouth and tongue. As she sated Lavinia’s exploding cunt, she drove her forefinger deeply into the quaking girl’s anus. Lavinia thought she would pass out if she did not stop coming soon. One wave of ecstasy after another washed through her. She felt faint. Then the redhead quickly shifted and buried her face into the dripping pot of Matilda’s inflamed sex. Matilda elevated her slender legs and squeezed her eyes shut as the tongue slithered hot and foaming between her legs, sucking, lapping her outer labia, her thighs, her asshole, then fastening onto her swollen clitoris and sucking there until Matilda’s crotch burst in a purity of mindless white orgasm.
The whipping soon became a promise forgotten, and the girls found themselves free of the restrictions placed on their emotions by the subservience demanded by the whip. The redhead too, free of her role as master, became realized in her play with Lavinia and Matilda, until, laughing and giggling like schoolgirls, the three embraced on the bed, and it was now the redhead’s turn to pacifically enjoy the dual ministrations of Lavinia and Matilda. They lay on either side of her, Matilda kissing and sucking at the redhead’s large, full nipples, and Lavinia kissing and licking the redhead’s wonderfully smooth thighs and the pouting little lips of her pussy.
They worked on the redhead until she lay completely in their power. First, Matilda made her come, then Lavinia, then Matilda again, switching off until the woman was caught in what seemed a permanent throe of orgasm, jerking and twitching, her long, pale legs quivering and her back arched. She moaned and babbled incoherently, caressing their faces and touching the point where their mouths fit against her blossoming cunt. When she lay finally exhausted and unable to move, the door opened and the doctor came in. He looked serious. The two girls sat up and, taking a towel from the bedstand, began to wipe themselves.
“Well, girls, what do you think of dream testing so far?” he asked.
“It isn’t over, is it?” Matilda replied.
“I’ve certainly got a few fantasies that haven’t been acted out here yet,” Lavinia said.
“No, you aren’t finished with dream testing,” the doctor said. “But it’s my habit to check on you occasionally, to make certain that you don’t forget the reality of your situation. Can you give me some impressions of what has taken place so far?”
“I haven’t been really surprised by anything that has happened,” Matilda said. “Most of the action relates directly to certain fantasies that I always considered common - the black man, for instance. And the masochistic thing, which turned out a little strangely, seeing as how our pretty little redheaded friend ended up in our power, rather than the other way around. But I expected things to be a little more bizarre, you know, like you must have understood things about us, from your vantage point of analyst, that even we do not know, and it is the enactment of those fantasies I looked forward to.”
“I feel more or less the same way,” Lavinia said. “And I have to confess that, although it seemed clear when you explained it, I really don’t understand now why we’re doing this.”
“To find out which of your fantasies are actually palatable to you and which are not,” the doctor said. “You see, my goal is to orient the patient totally with his real sexual nature, or personality, so he will be absolutely certain of himself when confronted by the unnatural conditions of the outside world. If you were on the street, and someone approached you and asked if you’d like to come along with them, to serve as whipping post at a party for local sadists, you could honestly say now that, although it may be appealing in the abstract, you really don’t enjoy being beaten. Isn’t that true?”
“I suppose,” Lavinia said. “But there’s more.”
