The following story is based upon an idea by Robert A. Heinlien.
(ff, mc, sf)
Dr. Jeffries: As you know, the alien slug is parasite, able to genetically adapt itself to control a wide variety of hosts. It is our belief that the slugs move from planet to planet, enslaving the indigenous life forms as hosts and then using them as soldiers to invade the next world. The slugs and their elf-like alien hosts began exploring the Earth and abducting humans in the middle of the last century, apparently to study and find a way to adapt themselves to use humans as hosts. Beginning in the late 1970's we began seeing invasions of the large slug that rides on the back of a human host. However we are now dealing with a new type of slug, one that is specifically adapted for a female human host.
Dr. Jeffries continuing: [Referring to MRI film of patient Matthews, attached as Exhibit A] This new slug enters the vaginal opening and occupies the upper third of the host's vagina and part of the uterus. The slug, through this tendril here, penetrates the uterine wall and attaches itself to the sacral portion of the spinal cord. The tendril links with the mind of the host and triggers a flood of parasympathetic nerve impulses which are normally only generated during intense sexual stimulation.
Dr. Jeffries continuing: [Referring to photograph of vulva of patient Matthew's, attached as Exhibit B] As you can see, the parasympathetic nerve impulses cause the arteries to the external female genitalia to dilate, causing the inflow of blood to increase and the outflow of the blood to decrease. The vulva of the host becomes swollen and sensitive to stimulation. The labia majora spread apart as the labia minora become engorged and distend from the host, causing the clitoral hood to pull back and expose the clitoris and clitoral glands. The clitoris swells up to several times its normal size. The flood of parasympathetic impulses also stimulate the vestibular glands to continuously secrete and lubricate the lower vagina, clitoris and labia. In nature, human females are only briefly able to achieve a state of arousal like this and then only after intense sexual stimulation and immediately prior to climax. However the slug is able to permanently keep its female host in this sexually aroused state.
Dr. Jeffries continuing: [Referring to MRI film of patient Matthews, attached as Exhibit C] The slug sends tendrils to the ovaries, preventing ovulation and menstruation and triggering the production of the female sex hormone estrogen. The estrogen will probably cause the breasts of the host to enlarge and stimulate the mammary glands for milk secretion. It will also cause increased vascularization of the skin of the female host, making their skin clearer, softer, and more sensitive to touch. The estrogen may make the uterus enlarge, possibly allowing the female host to carry more than one immature slug, possibly a great many more.
Dr. Jeffries continuing: [Referring to MRI film of patient Matthews, attached as Exhibit D] Once implanted inside a host, the slug is able to move along the vagina between the vaginal opening and the uterus. It can descend to stimulate the sensory nerve fibers leading to the clitoris and the urethral sponge, in the area commonly known as the Grafenburg or G-spot. This makes the vulva of host, and especially the clitoris, extremely sensitive to stimulation. In fact any stimulation will be sufficient to trigger an intense, pleasurable sense of physiological and psychological release ...
The Director [interrupting]: An orgasm.
Dr. Jeffries: Yes, an orgasm, the likes of which would rarely occur in normal human sexual activity. We believe it is by the means of these intense orgasms that the slug gains control of the female host. As I previously mentioned, the slugs that we have encountered before were much larger and took immediate and complete control of their host by riding upon the upper back of the host and affixing numerous tendrils to the spinal cord. However this new type of slug only attaches one of tendril to the spinal cord, and then only at the lowest part of the sacral region, so control of the host may be minimal at first.
The Director: So this new slug gets its host to do its bidding through sexual reward?
Dr. Jeffries: Perhaps. Perhaps the slug is able to exercise greater control while the host is sexually stimulated. What we do know is that the female host is constantly driven by an overwhelming desire to stimulate her permanently aroused genitalia through sexual contact until these intense orgasms are achieved. And it is by sexual contact that the slug reproduces itself and claims a new host. From what we are able to gather, Mary Calvert infected Jack Neal who in turn infected Jasmine Harmon. Jack Neal later infected Agent Matthews and then Matthews infected Tammi ... I mean, Nurse Lockhart.
The Director: And Jack Neal was not affected by the slug?
Dr Jeffries: No, it appears that human males are merely unknowing carriers for the slugs. The slug is not able to mature or attach itself to the spinal cord of a human male, and therefore is not able to exercise any control over the mind of a human male. The immature slug remains in the ejaculatory duct of the prostrate gland of the human male. During sexual arousal, we believe that the immature slug extends into the host's urethra, most likely to detect the presence of a female host. If a female host is detected, the immature slug divides by binary fission and creates two new genetically identical creatures, just like an amobea. One slug is ejected into the female host with the seminal fluid from the male host during ejaculation. The other slug remains in the male human to later infect additional female hosts.
The Director: Then why did both of the slugs leave Jack Neal and enter Agent Matthews?
Dr. Jeffries: It is our belief that the slug that initially entered Agent Matthews was able to read her mind once it had attached itself to her spinal cord. The slug inside of her somehow communicated the situation to the slug that was still in Jack Neal. The slugs realized that the best chance for escape was in Agent Matthews and the second slug entered her during their continued sexual intercourse. Agent Matthews then implanted this second slug into Nurse Lockhart.
The Director: And these things chewed right through the condom?
Dr. Jeffries: I don't know if they have teeth, but yes, it appears that the slugs were able to easily penetrate both the condom and the pantyhose that Nurse Lockhart was wearing.
The Director: Do we know how quickly these new slugs are able to reproduce and spread to new hosts?
Dr. Jeffries: No. As of now, they haven't reproduced while in Agent Matthews or Nurse Lockhart. However we examined the secretions that were found on the bedsheets taken from the hotel room in Louisville ...
The Director [interrupting]: Secretions?
Dr. Jeffries: Sometimes the Skene's glands in the vulva are capable of secreting a clear fluid which squirts during orgasm. Normally very few women are able to achieve an orgasm like this. However from the amount of secretions that we found on the bedsheets, it appears that a female host is able to secrete copious amounts of this fluid during orgasm. In female to female contact, the female host may use this squirting orgasm to lubricate the vaginal opening of the female she is infecting, allowing the slug to easily enter the new host. We were able to identify DNA in the secretions that matched the DNA taken from hair samples of Mary Calvert and Jasmine Harmon that were recovered from their apartment. However there were four other distinct DNA samples that we were not able to match.
The Director: Four! So the slugs may have already spread to four female hosts in addition to Calvert and Harmon?
Dr. Jeffries: I cannot say for certain, but probably yes. That would mean that each slug is capable of dividing and creating a duplicate of itself at least two or three times per day. There would be eight female hosts now, counting Agent Matthews and Tammi ... Nurse Lockhart.
The Director: Yes, yes, of course. Thank you doctor.
[The Director instructed that the following exchange between him and Dr. Jeffries be omitted from the two copies of the transcript.]
Dr. Jeffries: You knew that Agent Matthews would be infected. You wanted her to be infected ...
The Director: It was imperative that we discover what effect these new slugs had on a female host. Agent Matthews knew the risks ...
Dr. Jeffries: And what about Tammi? I lost my best nurse. You didn't ask her to volunteer, you didn't inform her of the risks ...
The Director: You should be fortunate that you now have two female hosts to study.
Dr. Jeffries: [inaudible]
The Director: I don't have time for this, doctor.
[The meeting was concluded. The Director instructed that an original transcript and one copy be prepared and the original tape destroyed.]
"C'mon Heather, the mall is about to close and we need to get a move on."
"Just a sec, mom." Heather flipped through some shorts that were on a display rack by the aisle. She found a pair in her size and held them up to her mom. "Can I try these on real fast? Pleazzzzze?"
"Okay, hurry, hurry, hurry." Nadine Cooke watched her daughter disappear into the dressing rooms. She had been spoiling Heather more than usual. This was her daughter's senior year in high school and the last year that she would be living at home. She had been accepted to attend the University of Kentucky in the fall and was already making plans to get an off-campus apartment with her friends. Nadine looked down at the bag of clothes that she had just bought for Heather and wondered if this month's child support check would pay off what she had charged on her credit card.
Heather exited the dressing room and quickly scooted back over to her mom.
"You weren't in there long enough to try that on. Did you change your mind?"
"You're not going to believe this, mom, but there's a sales girl in there going at it with a customer!"
"You're kidding me! She took a guy into the changing room?"
"No, she's doing it with a woman," Heather said, hanging the shorts back on the rack. Someone moaned loudly in the dressing room. "Let's get out of here," she giggled.
They quickly left the department store and entered into the main area of the mall. Several of the smaller stores on the mall already had their security grates down and they could hear the sound of a vacuum cleaner over the Muzak. They walked pass the Fredericks of Hollywood store and Heather peeked through the security grate. She reached out and put her hand on her mother's arm.
"Oh my God, they're doing it too!" she whispered excitedly.
Nadine joined Heather at the grate and looked in. A customer was bent over the counter in the back with her shirt open and her skirt pulled up around her hips. Her breasts were resting on the countertop and wiggled back and forth. A sales girl was behind her, hands on the customer's waist and pelvis pressed against the customer's bottom, moving her hips in such a way that it looked like she was pushing something into the customer. The customer's face showed a confusing mixture of emotions. It was like she was horribly frightened and wanted to pull away and yet was so incredibly turned on by what was happening that she was unable to stop. The sales girl was obviously enjoying herself and came noisily as they watched. Heather saw that the name tag pinned on her blouse read ‘Melanie'.
The customer suddenly gripped the countertop and moaned loudly. She threw her head back and her breasts left the countertop and jiggled in front of her as she began moving her ass in perfect rhythm with the sales girl grinding against her from behind. All traces of fear were gone from her face, replaced with a look of intense lust.
Nadine looked over and saw that her daughter appeared to be mesmerized by what she was seeing. She stepped away from grate, pulling Heather along with her by her hand.
"What are the odds of seeing something like that twice in one night?" Heather said, looking back over her shoulder at the store. "I wonder what it feels like doing a girl?"
Heather turned and smirked when she saw her mother's stunned expression. "Just kidding, mom."
"I'm going to say something to this cop." Nadine made a bee-line for a blond-haired police officer who was walking towards them.
"Excuse me, officer. My daughter and I just saw two people having .. um ... sex in the Frederick's of Hollywood store."
"I'll have mall security get right on that, ma'am. Of course, I'll need to a take a statement from you and your daughter. Come with me and we'll do that back in the mall office."
"Er ... we're kind of in a hurry, officer, and I don't want to press charges ..."
"But I am going to press charges, ma'am. And if you give me a statement, then you may not have to go to court to testify. The mall office is right back here. It will only take a few minutes and then you two can go."
Nadine looked at Heather, shrugged her shoulders, and followed the police officer. Heather stared at police officer as they followed her through the mall. Her breasts were huge and from the way they moved around it was obvious that she wasn't wearing a bra. Heather couldn't see any panty lines either. When they got to the mall offices, the officer turned to hold the door for them and Heather saw that her pussy bulged against the crotch of her uniform, creating what the boys at school were calling a ‘camel toe.'
They entered a reception area. The secretary appeared to have gone for the day and half of the fluorescent ceiling lights were turned off.
‘I'll take your statement first, ma'am," the officer said to Nadine. She pointed to a couch in the reception area. "Your daughter can wait here until it's her turn."
Heather sat down on the couch and her mother and the police officer entered an adjacent office and shut the door. She picked up a three month old copy of ‘Vogue' and began flipping through it. Muzak blared at a insanely loud volume from a speaker over the couch.
Heather looked up at the clock. Ten minutes had gone by.
The sales girl and the customer from the Fredericks of Hollywood store entered the waiting area. The customer had exchanged the clothes that she had been wearing for a pair of black vinyl mini shorts and a red teddy that she wore under her unbuttoned white blouse. They walked past Heather and entered the office. Heather wondered what kind of trouble they were going to get for fucking in a public place.
Heather flipped through another magazine, bored out of her wits. She looked back at the clock. The mall had closed a half-hour ago.
She tossed the magazine down and stood up. "This is ridiculous!"
The couple from Frederick's had not knocked on the office door and neither did Heather. She turned the doorknob and barged through the door ...
... and stopped in mid-stride, staring in disbelief.
All of the office furniture was pushed over against the wall and the customer from Fredericks was lying on her back in the center of the floor. She was locked in a naked embrace with a pregnant woman sitting on top of her. They were rubbing against each other and a black stringy thing twitched between them, seemingly connecting their swollen pussies ...
There was a crackling noise and Heather turned and saw the police officer advancing on her. The police officer held a stun gun in front of her and squeezed the trigger again. It made another menacing, crackling noise as electricity arched across its prongs.
"No! Not my daughter ..."
Heather saw her mother sitting on the floor in the far corner of the room. The sales girl from Frederick's was standing next to her.
"Mom!" Heather dodged around the police officer and raced over to her mother's side. Her mom was sitting against the wall with her legs spread open in front of her. Her underwear was lying on the floor next to her.
"Mom, are you alright? What have they done to you?" Heather got down on her knees beside her mother. The police officer shut the door to the office and stood in the front of it. It was the only exit to the room.
"Oh Heather ... they put something in me ... it's moving ..."
Heather looked up and saw the sales girl standing over her. "What did you do to my mom?"
"Your mother is fine. But for some reason, she is fighting against her Master possessing her."
"What are you talking about?"
"Your mother has been given a Master and is becoming host-slave. Sometimes the transformation to host-slave is instantaneous. Sometimes there is resistance on the part of the host and the process takes longer."
Heather saw that her mother had closed her eyes and appeared to be chanting to herself. Heather put her arm around her mom and stared at the two naked women in the center of the room. She pointed at the black tendrils that were linking them together.
"Is that a Master?"
"There is a Master in the pussy of each host-slave. What you are seeing are their communication tendrils which have descended out of their pussies and joined together to direct conference and share information with each other."
"I saw you in the Frederick's store. Were you turning that customer into a host-slave?"
"Yes. You saw me transferring a Master into the customer's pussy. Tomorrow she will come and work with me at the store and together will recruit new host-slaves. By tomorrow evening, all of the women that work at the mall will be host-slaves. We will then be able to efficiently recruit customers coming into the mall."
Heather decided to stall for time while she tried to think of a way to get her mom and her past the police officer and out of the room. "Um ... do you like being a host-slave?"
"Yes. What is your name?"
"Heather."
"Heather, my name is Melanie and being host-slave is the most fulfilling thing that has ever or will ever happen to me."
Melanie unbuttoned her shirt. "Your body goes through fantastic changes and becomes so beautiful. Your skin becomes softer ... your breasts become larger."
She took off her shirt, showing Heather how her breasts were tightly squeezed into a black bra. She unfastening her bra and slipped it off. Heather saw a red mark cutting across the bottom of her breasts where the wire support of the bra had been pressing against them.
Melanie dropped the bra on the floor. "I will no longer be able to wear that bra. My breasts have grown a full cup size in two days." She ran the tips of her fingers in circles over her dark, pierced nipples. "My nipples stay permanently erect now and they are so sensitive."
Melanie unzipped her skirt from behind and let it drop to the floor. She pulled up the sides of the crotchless panties that she was wearing and showed Heather the bulging pierced lips of her swollen pussy. "But best of all, your pussy becomes ... perfect. You stay permanently aroused and can have the most incredible orgasms with the slightest stimulation. You lose all of your sexual inhibitions. You can have sex all of the time, without fear of pregnancy or disease ..."
Her mother opened her eyes. "Don't listen to her, Heather."
"Your mom is denying herself this pleasure and is prolonging the inevitable. She will be host-slave. You will be host-slave."
Heather began to protest, but Melanie cut her short.
"You do not have any choice in the matter, Heather. If necessary we will subdue you with the stun gun. It will not hurt you, but your mother can tell you that it does not feel pleasant. And the stun gun will briefly overwhelm your neuromuscular system, so you will miss out on some of the incredible feelings that you would otherwise experience when being taken by your Master. Whenever the Masters of two host-slaves link together, its like the greatest fuck of your life."
Heather watched the couple writhing on the floor. "I don't want to be shocked," she said, rising to her feet. She began to unbutton her shirt.
"Heather, no!"
"It's okay mom. Like Melanie said, its not like I have any choice in the matter."
Melanie smiled as Heather slipped out of her clothes. "I am very proud of you, Heather. The purpose of the host-slave is obedience."
"Let's just hurry up and get this over with."
The women in the center of the room separated. The customer stood up and began getting dressed, her black tendril snaking back up into her pussy as she slipped into her clothes. Heather walked over and laid down on the floor in the same spot and position as the customer had been in. The pregnant woman that had been sitting on the customer stepped over Heather.
"My name is Mary," she said, rubbing her swollen stomach. She looked like she was two or three months pregnant. "As you can see, I'm full of Masters. When I have an orgasm, your new Master will slide out of me. If you like, I can bring myself to orgasm through physical contact between my pussy and your pussy, allowing your Master to pass directly from me into you ..."
"Ummmm ...," Heather said in a quiet voice. "I'm not sure if I want to do that ..."
"I understand. Humans have inhibitions that host-slaves do not. I can manually stimulate myself without having physical contact with you."
Mary squatted down over Heather and began to gently finger her clit. Heather tried shutting her eyes but that made things worse. She looked up and watched Mary's glistening wet pussy lips quiver under her probing fingers. She stared at Mary's beautiful breasts and began to wonder if hers would soon be that large, if her nipples would really be erect forever ..
Mary suddenly cried out and her cum spurted from her in a long, wet stream that drenched Heather's pussy. Heather flinched as the warm fluid and something that felt soft and spongy landed on her. Her pussy tingled as she felt something like a string slither inside of her and there was a stinging sensation in her back right above the crack of her ass.
Heather gazed up at Mary's dripping pussy. For some reason, she suddenly felt so incredibly horny ...
... Mary was so beautiful and it was Mary that just made her pussy ache like this and she needed to fuck so bad and Mary's pussy was so beautiful and Mary's pussy smelled so delicious and she wanted to make Mary cum again and soak her pussy and she wanted to fuck Mary until her pussy was as beautiful as Mary's pussy and they both were cumming ...
Heather reached up and gently pulled Mary down to rest on top of her.
"Fight it, Heather," she heard her mom say. "If you concentrate, you can fight it."
Heather closed her eyes. She and Mary began grinding together.
Her mom couldn't bear to see what was happening to her daughter. She closed her eyes and concentrated, pushing away the thoughts that were continually bombarding her mind.
‘I'm tough as nails,' she thought. ‘I'm a fighter and my daughter is a fighter ...'
She repeated the words in her mind over and over like a mantra.
‘... my daughter is a fighter ... my daughter is a fighter ...'
She was so focused that she didn't hear Heather scream when she had her first orgasm.
‘... my daughter is a fighter ... my daughter is a fighter ...'
Something touched her on her shoulder and she opened her eyes. Heather stood naked before her. Nadine watched in horror as the glistening, pink lips of her daughter's obscenely aroused young pussy bulged outwards and parted open with a soft wet noise ...
... Her pussy lips are opening like beautiful petals, and her swollen clit is like the blossoming bud of a flower, dripping with sweet nectar ... Oh God, what am I thinking ...
Nadine closed her eyes and her mind wandered. Her hand slipped under her dress and she began masturbating, her pussy swelling beneath her probing fingers ...
Heather looked down at her mom and smiled.
"I am host-slave," she said.
