During the next day, Lavinia and Matilda walked through as much of the institute as they were allowed, and found nothing that resembled a likely storage place for the antidote. They tried speaking casually about the drug to several attendants, but no one was cooperative. At the end of the day, they were very depressed.
“I’m going anyway,” Matilda said while they were in the shower.
“It’s a big risk, Matilda. I want to go, too, but I don’t know. Without memory of our previous lives out there, we can’t have any idea what to expect. But if you really think you want to do it, I’ll go with you!” Lavinia decided finally.
“Oh, Lavinia, I love you!” Matilda laughed and threw her arms around Lavinia’s shoulders.
Actually, it was easy.
Matilda sneaked into Lavinia’s room in the middle of the night, and together they went down the corridor, on tiptoe, and out into the green yard. The moon was high, and its light bathed the wall and the trees beyond. They could see the spires of high buildings in the distance, and hear the mumble of cars. It took them a few minutes to find a low place in the wall and a tree up which they could climb to drop over. And be free.
When they dropped to the ground on the other side, they were exultant with their deed. They wanted to sing and laugh, but dared not until they had walked a mile or so along the path that led toward the city. Then they shrieked hysterically with joy and danced and skipped along the road for over an hour, until they were very near the city. A car passed them on the road - and then another. They reached a paved street. Ahead was an open diner, then a cluster of residences, and beyond, the teeming neon lights.
Lavinia was pleased to see, through the glass of the diner window, that the simple white frocks she and Matilda wore were not so unstylish as to attract unwanted attention. Two girls sat at the counter wearing colored slipovers cut along parallel lines. Their clothes would not give them away, and they had all night - until morning - when the doctor would discover they were gone and doubtless send out an alarm for them.
“Oh, it’s wonderful to be free!” Matilda exclaimed. “What shall we do?”
“I was thinking the same thing,” Lavinia said. “We don’t have any money. Maybe we can just walk around the streets and see what happens.”
“I suppose we don’t have any choice,” Matilda sighed.
Then a car pulled off the road and a young masculine face peered out the window on the passenger side.
“You girls want to go to a party?”
The boy was a few years younger than the two escapees. They approached the car, and Lavinia bent down to look inside at the driver. The person behind the wheel was a girl - about the same age as the boy. She was nude from the waist up.
“What kind of party?” Lavinia asked timidly.
The blond youth laughed incredulously. “What do you mean, what kind of party? What kinds of parties are there? We’re rounding up people who want to go to a party. Lots of other people are there and anything you want to smoke, drink, or eat, too! How about it?”
“Let’s go,” Matilda whispered.
“Well, why not?” Lavinia dared bravely.
The boy reached into the back and opened the back door.
When Lavinia and Matilda had seated themselves, the girl glanced over her shoulder and said “Hello.” She pulled back onto the street.
“It’s a real shame,” she said, “that prices at the fornicatoriums have gone up! It isn’t right that people of our class should be denied their facilities. But, oh well, we make do with what we have, and if you ask me, we come as often and as well as anyone.”
“That’s right,” the boy said. “I think it’s better to have private parties, anyway. I know it’s a little weird, but when those old ladies at the fornicatoriums start pawing me, it makes me feel creepy. I hate to come on like a freak about it, but that’s how I feel, and I’d much rather have a party like the one we’re having tonight, rather than pay to go into one of those lousy fornicatoriums.”
Lavinia wanted to ask what a fornicatorium was, but she thought better of displaying her ignorance. Besides, the name told enough.
“We shouldn’t let them know we aren’t familiar with all this,” Matilda echoed Lavinia’s thought into her ear.
“Say!” the girl spoke to Lavinia, whose eyes she had caught in the mirror. “What’s your scene?”
“I ... I’m sorry,” Lavinia stammered. “What do you mean?”
“You know, scene, baby,” the boy blurted good-naturedly. “What do you like to do, and to what kind of people?”
“Oh, just everything, I guess,” Lavinia tried to play it safe.
“Beautiful!” the girl said. “And what about you, sweetie?”
“I feel the same way,” Matilda said.
“That’s terrific! We need people like you to round the party out. We’ll be at my place soon, and then the fun can really begin. Why don’t you give them a little aphrodisiac now, Johnny, so they’ll be good and warm by the time we arrive?”
Johnny reached into the glove compartment and handed two capsules into the back seat. “Go ahead and take them,” he said. “It’s prime stuff, smuggled in from the East. It’s rhinoceros horn, not like that cheap synthetic crap you get in the local corner drug store.”
Lavinia felt a little nervous, but rather than cause a disturbance, she took the capsule and swallowed it. Matilda did the same.
The girl turned off on a shady street lined with identical five-story apartment buildings, and at the second parking lot, she shut the car down. “Let’s go!” she said.
They got out of the car and went into an elevator on the inside of the lobby. The elevator jerked them up with a steady swishing sound. Lavinia felt warm and tingly. Her breasts were swelling taut, and she itched between her legs.
The boy smiled at her and, reaching out, touched the tip of his forefinger against one of her nipples, visible through the cloth. The sensation was extravagant. Immediately, she felt aroused. Her cunt was lubricated. She wanted to be touched all over.
The blonde slipped her arm around Matilda, and with her right hand, she patted the little mound of Matilda’s crotch. Matilda flushed immediately and pulled the girl close, so that their stomachs were pressed together.
“The aphro is working nicely, isn’t it?” the blonde asked.
“I’ll say!” Matilda hissed.
Then the elevator stopped, and the door slid open onto a red-carpeted hallway. A moment later, they were passing through the door of an apartment.
The lights were blue, red, and green, and in one corner, a strobe flickered. Ten or twelve unclothed persons sat about the floor smoking from a communal pipe. Most of them were quite young. They looked up with glazed eyes as the foursome entered.
“We’ve come back with some new blood,” the boy called.
A chorus of cheers went up from the group.
“Let’s get started now!” someone called from the corner.
The girl turned to Lavinia, and without hesitation, she began to undo the snaps on her frock. The garment fell to the floor. The boy did the same with Matilda, and then fell to his knees and buried his face between her legs. Matilda glanced at Lavinia with an expression on her face that said, “Well, here we are. Let’s enjoy ourselves.”
“Come on, baby,” the blonde girl whispered into Lavinia’s ear, “he’s down on the floor, and let me start you.”
Lavinia lay down on the carpet with the strobe flashing in her eyes, her bare back and bottom prickled by the weave of the carpet.
“Your pussy is beautiful!” the girl sighed as she slipped down between Lavinia’s trembling thighs. She pushed her legs apart and began to lap at the tender thigh flesh. She slipped one hand under Lavinia’s round buttocks and lifted her slightly, then pushed her finger into Lavinia’s anus. The aphrodisiac capsule had softened Lavinia’s reflexes and involuntary muscles, and she was so relaxed that the finger went all the way in. It felt like a huge, thick cock up her ass. The girl began to lick her pussy, sucking the labia until they began to swell. Then she found the clitoris and rolled it under her tongue. Lavinia could not have fought down the drug-intensified sensations, even had she desired to do so. The girl’s tongue was a warm blade of honey that seeped into her loins and kindled a deep glow in her. Lavinia held her legs up and stretched them apart to bare the soft pink insides of her cunt to the probing tongue. The finger moved rhythmically in the tight passage of her asshole.
Matilda lay on her back now, with the grunting blond youth astride her loveliness. Her long, willowy legs were wrapped around his back, and her arms twined around his muscled shoulders. Her mouth fastened to the youth’s neck. He pumped into her with long, certain strokes, each probe eliciting a long sigh from the drugged girl. Suddenly, she threw her head back, grinning and laughing hysterically, as the juices broke and flowed through her in her first orgasm. The youth did not slacken his pace, but drove her on into a long, shuddering orgasm that made her whole body writhe and twitch spasmodically.
A delicately limbed youth with moist, brown eyes and long, black hair knelt between the boy’s legs, licking his buttocks and finely haired thighs.
Lavinia came. It was like a series of small explosions at the base of her spine, but she found—much to her surprise—that the spectacular orgasm did not sate the lust fired by the aphrodisiac.
“Oh, make me come now, please!” the girl said. She pulled herself up and squatted down over Lavinia’s face. The tightly coiled blonde pubis pressed against Lavinia’s lips. Lavinia hungrily thrust her tongue into the wet cunt and sucked with all her strength, running her tongue fervently over the hard clitoris. The girl moaned and ground her hips in a fast, circular motion, her hands winding in Lavinia’s hair.
A large, smooth-muscled black youth approached the blonde girl from behind, squatted over Lavinia’s stomach, and grabbed the girl around the waist with his left arm. With his right arm, he guided the glans of his big, thick cock into the blonde’s anus. She laughed for joy when she felt the prod, and she adjusted her hip motions to push against that prick that tantalized her from behind. With his right hand, after positioning the prick in the girl’s behind, he massaged Lavinia’s fiery cunt. She spread her legs to receive the delicious sensations. The blonde was coming. She pressed down against Lavinia’s mouth, quaking and jerking with the explosion. When she was finished, she rolled off Lavinia and lay quietly to catch her breath. The black man pressed his lips against Lavinia’s mouth, and she felt the hot slithering of his tongue in her throat. Then he was sucking her breasts. It felt wonderful.
“Oh fuck me! Fuck me!” she babbled.
He slid down, gripped her legs and positioned them over his shoulders, and came forward and pushed her knees back beside her head. His cock was thicker than Lavinia’s wrist. He wedged the heavy yellow glans between the fiery lips of her cunt and began to nudge it in with short stabbing pushes. She felt as if she were being split open, but the feeling was not a bad one. With a final effort, the youth drove his cock all the way to his nuts. A lance of fire shot through Lavinia’s ardent flesh. She pushed her buttocks up and locked her ankles behind the man’s neck. Her right hand found the heavy, tight sack of his nuts, and she rubbed them gently as he gave her stroke after stroke of pure pleasure. Again, she came. It seemed that each orgasm she achieved only whetted her appetite for more.
“Let me suck that big, marvelous dick!” she whispered passionately in the youth’s ear.
He withdrew and rolled onto his back. Lavinia scrambled down and placed herself between his ebony thighs. She licked his smooth black skin until it gleamed with the moistness of her saliva. Then she slithered her tongue into his asshole and flicked it in and out until he was quivering with anticipation. In the back of her mind, she was slightly appalled at her own actions, but the drug was her primary motivating force, and the drug demanded more and more. She ceased her ministrations in the man’s asshole and carefully eased his tight purple scrotum into her mouth, lovingly caressing the hard, large nuts with her tongue. He moaned and touched her lips with his fingertips. She released the nuts, and with the tip of her tongue, she traced long wet lines up the length of his hard, black dick, stopping before her tongue touched the swollen glans. She did this several times, noticing that each teasing lick made the huge prick expand until finally it stood up in her vision like an enormous glistening totem pole. No longer able to contain her passions, she knelt and licked the taut glans furiously, over and over, until with a cry, she had to suck the thing into her mouth. It was delicious! It was so large she could feel her mouth stretching to take its circumference, and she could manage to get only three or four inches beyond the head. She sucked as if she was trying to drain him through his pores. Then she felt someone touch her behind. A woman’s soft, damp hands spreading her cheeks, then the blunt end of a cock pressed against her anus, broke through, and sank deep inside her. She looked over her shoulder and saw the redheaded girl, no more than fifteen or sixteen, with a rubber dildo strapped around her waist. Another girl - a brunette - lay on her back under this girl with the dildo, and she pressed her face between Lavinia’s legs, lapping at the dripping pot of her cunt, occasionally switching to the flaming cunt of the girl who stabbed into Lavinia’s asshole again and again.
The blonde who had originally made it with Lavinia reappeared. She sat on the black youth’s face, receiving his marvelous tongue in her renewed pussy, bending forward and licking Lavinia’s neck and shoulders. Lavinia came so long, so hard, that she began to grow dizzy. Her head was swimming. She wasn’t certain what had happened, but then she was detached from the group, lying on her back, and the redhead lay on top of her, the dildo crammed into her snatch, licking Lavinia’s breasts and driving the rubber cock as deep as any real cock had ever been. Lavinia was hysterical. She wound her legs around the girl’s buttocks and humped her with all the energy she could muster.
The drug was at its most intense level now, and Lavinia was a blind fury bent on indulging herself in every extravagance permitted by the structure of her body. She clung to the redhead, her teeth clenched on the firm neck. Her legs wrapped around the grunting girl’s waist, and with all her strength she could throw herself against the dildo that went in and out like a hot poker. She couldn’t get enough. She rolled onto her side and pushed the redhead onto her back, pressing one hand against the girl’s fat, inflamed breasts, and with her other hand snatching the dildo away. She held the staff in her right hand and leaned across the girl’s waist to pinion her, although obviously no force was necessary, and with the fingers of her left hand she parted the swollen, frothy lips of the cunt, nestled in a wild sporran of curly red hair, and plunged the dildo between the lips of the gaping crease. Thick, gauzy lubricant oozed up around the shaft, making Lavinia’s hand sticky. She twirled the instrument and moved it in and out rapidly. The redhead shrieked and quivered as Lavinia drove her through orgasm after orgasm. When she was erupting with ecstasy, Lavinia removed the dildo and slipped it deep into her own foaming pussy, then buried her face between the redhead’s hot thighs. She sucked the wet cunt lips into her mouth and thrust her tongue deep, licking and sucking at the tender juices of her clitoris. She drove the dildo as deeply as possible and began to spread the lining of her vulva with it. She could feel her come squirting and streaming down her legs thick and pasty. The blond boy who had called to them from the car was suddenly on his hands and knees lapping at the rivers of come glutting Lavinia’s thighs. Matilda knelt behind the boy and lapped at the crease of his shiny buttocks, her hand clutching and masturbating his rampant cock.
Couples uttered the floor, then threesomes and foursomes, all lathering naked, rutting and rolling with each other, copulating frantically, then changing partners to suck or be sucked, without preference, seeking only more ardent flesh to bend or yield to, lusting after the incredible gorging excess, rather than any simple essence of the act.
Lavinia and Matilda were like prisoners inside the hard shells of their lust. They knew that, had they not taken the chemical, they would not have entered thus into this affair; yet, the drug aroused their sexual heat and inclination to such a pitch that there was no choice but to vent those passions, as often and as fast as possible, until the passion and the drug were spent.
They came together once, in the sweating, glistening tangle of moaning and jerking flesh, their mouths fused, tasting the mingled juices of each other’s mouth, holding their sleek, warmed bodies, caressing, until each had found with her mouth the other’s tingling sex. Lying quietly in a corner, before being drawn back into multiple actions, they came long and sweetly, trembling and licking each other like impassioned beasts.
Lavinia found herself with a new dildo in her hand, dangling the straps and buckles intended to hold it in place. The blonde girl assisted her until the straps were right and the hard rubber prick stood up before her, fully ten inches in length, and greased with cold cream. Then she saw the girl’s brother, bent forward, resting his weight on his hands. Matilda held his boyish pink cheeks apart, pulling the anus open. As Lavinia gripped the dildo and started toward the youth, someone deposited a glob of petroleum jelly directly on his asshole. The shaft went in smoothly as he screwed his hips toward it. She had penetrated him with about half the length of the instrument.
She was like that when the door splintered and seven tall, muscled men in blue uniforms charged in. The people leaped to their feet and started for the doors. Everyone was screaming. Lavinia caught a glimpse of Matilda just as an officer sprayed her face with something from a small pressure can, and she sank down in a faint. Then Lavinia, too, was overcome by the gas, and she sank into a world of darkness and sleep.
When Lavinia awoke, she was sitting on a hard bench in a cool, gray room. Matilda sat beside her. They were both still naked and their bodies were bruised from the orgy they had participated in. Lavinia looked at Matilda. The poor girl was a real mess, and Lavinia suspected that she, herself, didn’t look much better. The antiseptic room they were in was cold, and she wrapped her arms around her shoulders, shivering.
“I feel terrible!” Lavinia whimpered.
“I’m sorry!” Matilda sobbed. “I’m sorry we escaped. I’m sorry for everything.”
“What are they going to do to us?” Lavinia asked.
“I have no idea. I wish the doctor were here. I wish I were back at the hospital.”
“So do I!” Lavinia said, and she meant it.
They sat in the cold, bleak room for what seemed an eternity. They didn’t know how long, but they were hungry, cold, and miserable.
Then the door opened and two men, middle-aged, slightly balding, in dark green suits, entered.
“Don’t bother getting up, girls.”
“Are we under arrest?” Matilda asked plaintively.
“I’m afraid so,” the tallest of the men spoke as they seated themselves on benches across from the two apprehensive girls.
“But why?” Lavinia blurted.
