A sex story set in a university biology department

A broad lazy sheen of winter sunshine settled over the green space
between the campus buildings, as Mary McGowan walked across the path
between two oak trees. She was in her final year of her Biology and Life
sciences PhD. For a 24 year old woman she was just on the plump side,
curvaceous is perhaps a better word for her actually. She wore a open
white lab coat, which flowed in the winter breeze, a tight fitting white
blouse (through which a dark blue lacy bra could be seen), a knee length
beige skirt and autumn leaf patterned dark tights. It was a mish-mash of
clothing, but it looked good. Or rather the woman underneath the clothes
would have looked good in nearly anything (or nothing at all of course).
She had long brown hair and a pensive look on her attractive face. Under
her arm was a clip board and heavy looking A4 size technical
pharmaceuticals and chemicals catalogue.

She walked though into a red brick 1960s built university block, took
the elevator to floor four, and then walked up to the only door in the
corridor from the elevator, it was a strong wooden door with no windows.
A sign on the door said "Authorised Personnel Only" in large red
letters. She fumbled for an access card and slid it through the card
reader. The door opened with a mechanical click, and an electrical
BURRRRP from the sounder alarm. She walked through and walked past cages
full of rats and mice all with scientific notes attached to their cages.

She went into room 414, which was locked and after using her access card
again, went through. Mike the lab technician had just finished cleaning
out a mouse cage and was putting mouse #5647 (or Sandy) back into her
cage. "Back you go you randy little maniac" he mused as she scamped
off to her wheel.

"Hows she been doing" Mary Asked.

"Fine no problems" he replied while going to the next cage and
attempting to catch mouse #5987.

Mike and Mary were great friends, and would occasionally give each other
a hug (especially after a pint or two after a Friday 'down the swan' at
lunchtime which had become department a tradition) but that was the
extent of their relationship. Mike had playfully groped her boobs once,
but more in mildly drunken fun than a serious attempt to bed her. She
did'nt mind this, men were supposed to be men, and a bit of friendly
playful behaviour was nice. Mary thought of herself as a feminist, for
equal rights and the like, but liked men generally. And liked them to
act like men.

Mary set the heavy catalog down, and then after checking the clip board,
took 1.8ml of liquid from a bottle, marked in handwriting  -œDH265 20%
by volume Solution" with a pipette. She carefully measured out 500ml
of distilled water and made up a working solution. 1ml of this she
placed into #5647, Sandy mouses's water bottle, writing on it that it
was dosed at 10X with the date and time. The rest she placed into a
working solution bottle. She then took a male mouse (number #4523, with
no name) from its cage and placed him into Sandy's cage. She then
checked an 8mm tape, and then set a video camera running pointing at the
cage.


DH265 was a prototype aphrodisiac drug. Its medical potential uses were
to help frigid women to want to have sex again. The old early female
aphrodisiacs, were based on the same philosophy as viagra, get the bits
stimulated ! But these had limited effect. A man might think its a good
idea to have sex just because he has an erection, but women are more
complicated beings.
DH265 is a cocktail of hormone stimulants and subtle brain chemistry
modifiers, and was designed to make a woman want sex from multiple
deeper levels. It was also still an experimental drug, and only had only
been tested on mice and (a little) on dogs.

Mary then walked on to the video room and fast forwarded through tapes
of the various mice in their cages, noting times that they had sex, ran
in the wheel and ate. This she typed into a database.
She had been working like this for a little over two hours when
Professor Gerard, one of her PHd supervisors, walked through into the
room and asked about the results trends. The drug worked, but side
effect statistical monitoring was important at this stage. Any side
effects showing up at this stage could mean that the university would
not be able to sell the rights. And this project had real potential to
make money for the research department.

Mary, typed the last figure into a database record, and then looked up
at him.
"Well the statistics show now, to the required probability levels that
there are no noticeable side effects, even with high dosing. And this
stuff continues to work even after 100 applications, there seems to be
little or none of the tolerance build up that was originally worried
about"
The Professor adjusted his glasses, slightly, and then coughed.
"So what you are really saying, is we could try human field trials"
He imperceptibly grinned as he said this, but Marys grin was more overt.
Mary, clicked a button on the computer ordering a printout.
 -œWell, heres the latest stats on a report, so whats next? Who do we
ask for permission, do the volunteers get paid, do we charge the boys to
join in the experiment?"
The last statement was an old joke and the professor ignored it.
"Don't worry about that, I have already have this agreed in principle,
I spoke to the legal department and the Dean yesterday. All we need to
do now is submit the request formally and hope; should know within six
months really"
Mary looked a little disappointed. Six months, which could, in
bureaucratic speak really mean a year! OR never!
"Don't worry, we can still wrap up the Phd, even if the field trial
work is taken on by someone else"
"Pity, I was hoping it could have been sooner, but I guess I can
follow it if GlaxoWelcoRoche take me on"
"Yes, heard anymore from them then"
"not directly relating to a job, I am hopeful though after the
November meeting; but look at this" Mary said, pointing at a graph of
side effect correlation, "gets better all the time."
The professor looked the graph, and then spoke.
"I know its either going to work on humans or do nothing, either way
its going to be safe, but these things take time Mary, just got to go
with the flow, I'm afraid"...

Professor Gerard took the printout and wandered out of the room, quietly
whistling to himself Wagners pilgrim chorus from Tanhausser.

Mary, sat back and quickly looked back on her time working at the
University. Here stockinged thigh felt nice sliding on the coarse nylon
of the office chair, and was distracting in a pleasant way.
In fact it felt just a bit too nice. Her hands felt a little too smooth
too, and her skin was pleasant to touch. She gently rubbed her arm as
she took stock of her work so far.

All the work for the Phd was done, it was just tidying up really. Word
smithing, and checking calculations. She currently had no boyfriend, or
rather, she was in Limbo boy-friend-wise. He had left the university for
a Job in Loughborough, and had not come down to Sussex now for six
weeks. It was as though the relationship was fading out. She suspected
he might have a girlfriend up there too, but strangely that thought did
not bother her today. Day dreaming about sex with him, she remembered
the first night they had together. She had been drinking white wine and
had smoked a little grass with her friends walking up to the old
refrectory. She remembered kissing him in the corridor to the dorms and
then him laying her down on the bed and pulling her knickers to the side
where he gently kissed her vagina. Although sexual and nice, she had
found it funny that he had kissed her there, and had laughingly pulled
him up to kiss her. After the kiss a hard condom wrapped penis was
pushed into her, hurting at first, but pleasure and excitement beating
that sensation into second place very quickly. Without thinking about
it, her hand slid up her thigh and with her middle finger under the
knicker elastic, began to probe her remarkably wet already pussy. This
was something she often did at night secretly, and she felt the same
warmth and comfort that she felt snug in bed just waiting to go to
sleep. Today it was as though she had forgotten where she was. She was
sitting in the video room with an open door where anyone could see her
who was walking past. Soon the middle finger was stoking the clitoris
and within a few minutes she brought herself to orgasm letting out a
loud whimper as she came. She opened her eyes and looked around. To her
embarrassment, she saw that Mike was watching.

"Oh sorry" she stammered.
Mike walked nearer, and asked if she was OK.
"Yes, yes" she said dreamily adjusting her skirt. She felt that she
should have been embarrassed, but felt slightly light headed, almost a
little high. She thought that perhaps Mike did not realise what she had
been doing. She looked at Mike and felt strong lust. She gazed at his
crotch, and the looked up and sweetly said,
"in fact Mike, I do feel a bit funny, sorry I thought I was alone"
and then she laughed a little. She then surprised herself and stood up
and wrapped her arms around Mikes neck, and pressed her forehead against
his, "promise to tell no one Mike" she said softly.

But as she did this she knew she was part making him comfortable, and
part turning him on. She thought to herself, briefly, I am seducing him.
She moved her left leg between his so that she pressed her tummy against
him. Her boobs squashed against his chest and felt very comfortable and
good. There was a pause as Mike looked into her green eyes, and then he
kissed her on the mouth, hesitatingly, as if seeing what he was allowed
to get away with it. Soon she felt his arms gently clasping her back and
then gently stroking her.
She closed her eyes and let him have free reign over body. She felt a
deep sexual yearning, and a warm pleasant slightly orgasmic feeling in
no particular part of her body, but just generally. His hands roamed
over her bum and by pushing her body slightly away from him, he cupped
her right bossom and kneaded it gently. She did not really have time to
decide why she was doing this but felt she would just do this anyway.
Soon Mary was very excited, to excited really to speak. She kissed and
pressed her groin into Mike, and her breath was quick. Mike, had an
erection that was rock hard and was rubbing against the hem of her skirt
though his trousers. He asked Mary if it was safe to make love to her.
She nodded, disengaged from him and lay down on the lab floor.

"Is it safe Mary, are you on the Pill?" he asked again, as he laid
down beside her quickly taking all his clothes off in the process. Mary
was not on the pill, but just answered "Yes its safe", but a thought
in the back of her mind knew it was not, but she just did not care. Mike
took her shoes off and rolled her tights off. He touched her vagina and
inserted one and then two fingers, she was very very wet. Mike leant
over and Mary kissed him on the mouth as he moved into position.
Mike gently inserted into her missionary position, she was very wet but
had a a nice tight pussy. Almost directly after entering her Mary seemed
to come, she grabbed hold of him with her arms, and squeezed her pussy
gripping his penis tightly in spasms. She had not felt the sexual
sensation as strongly before, and an idle thought flashed into her head
that she must be sexually maturing, as women get older they are supposed
to enjoy sex more. Mike entered deeper and began a gentle slow stoke.
Mary had her skirt bunched around her middle was closed eyed in sexual
ecstasy. Her head slowly rocked from side to side on the floor. She had
never enjoyed sex this much before. After a few minutes she built up to
a massive sexual climax, whimpering and yelling so much that Mike, after
asking her to be quiet several times, put his hand over her mouth. After
that Mike gently built up to his climax, releasing with a final thrust,
he french kissed her, as the waves of pleasure caught him and he
released his sperm into Marys pink soft folds of delight.

After the recovering a little, Mike got up, and helped Mary up with his
hand. She stood up and he briefly kissed her.
"You are a surprising one Mary"
"I surprise myself actually" she said. She took her tights
completely off and put them in her pocket and quickly slipped her
knickers back on. The afterglow of orgasm was still very strong and
intoxicating. Looking around she began to realise what they had just
done.
Mary now had a clear moment, what she had just done was very out of
character. The distracting feelings in her vagina were still there, and
she could feel a trickle of sperm making the wet patch on her knickers
bigger. In fact what she had just done was a crazy. She had made love on
the floor of a lab in which at least 20 people had access, with a a work
colleague in the middle of the day. She had also masturbated at her work
chair during the day. Slowly it dawned on her what had happened. When
she had made the concentrate, she must have spilled some on her skin,
she had unwittingly drugged herself with the experimental aphrodisiac.
Well a cocktail of drugs actually. Looking at her blouse, she saw a
stain on the upper left arm. It must have been the spill. She was
certain now. Damn, better get this off she thought, before I get even
more of this in my bloodstream. She took the blouse off and stood in her
skirt and bra.
Mike asked her what she was doing.
"Mike, errr damn, I think I have dosed myself with DH265"
"OH" Mike looked a little worried "Should we get you to hospital
or something"
"I don't really know, Mike, I do feel funny, maybe we should yes"
"Sorry, I mean I thought "
"Its ok Mike, it was great" she smiled softly at him. "Don't worry
I asked you to. But I don't know what to do now." Although she still
felt very randy and warm she was a little worried about the drug and how
much she had had.
The mechanical access card mechanism clicked. It was Mandy a fellow
research student. She looked in and then said " do you two want to be
alone ?" in a vaguely annoyed tone.
"Mandy " Mike said " Mary has just dosed herself with DH265, she
spilled it on her blouse"
"Hmmmm " Mandy said disbelievingly. She had seen them hug once after
the pub, and thought there might have been more to it.
"No honestly what should we do" Mike implored.
Mandy looked at them both, the blouse off made sense now, and she
believed them.
"well it should not be that dangerous, but maybe you should be
monitored, by the way does it feel any different"
Mary grinned, Mike looked embarassed and shuffled his feet.
"OH I see " Mandy said " Well Mary would you recommend it?"
"Only if you want be the randiest most unthinking girl on the planet,
damn, I'm not on the pill Mike"
"OH great said Mandy" eyeing the pair of them and guessing,
correctly, that they had just had sex in the lab.
After a small wave of panic, Mary thought back to the date of her last
period. She was due one about now, so probably it was pretty safe. That
'safe' she quickly realised meant, she could do it again. The drugs
effects kept pushing her mind back to thinking about sex. It was very
pleasant, but also a mild nuisance being so distracting.
Mike shuffled his feet a little more and said "Mary should I take you
home, maybe you ought not to drive in this state"
A twinkle came into Marys eyes, was Mike was going to be up for a night
of sex she thought ? Why yes he must be, mad enough to shag a work
colleague without even closing the door to the video room.
She certainly was up for it, even if she knew the yearning in her was
chemically induced. She really wanted it. She tried, unconvincingly to
play the innocent.
"Yes I feel a little light headed, please, err yes, that would help"
Mandy was not fooled for an instant." Have fun you two" she said
quietly through a wide grin.
Mike and Mary left the building, and walked to a students pay and
display car park.
"Get me home quickly" Mary thought to herself "I want you again,
this stuff is amazing, it does not just make you horny, it makes the sex
incredible too", but instead of talking she rolled her head onto Mikes
shoulder and thought of the cum and juices coating her pussy walls, and
hard penises and sensations and smells of sex.
Mike reversed out of the parking space and swiftly drove back to his,
not Marys flat. Mary did not even seem to notice. After all, all she
wanted was a stiff cock and a man to drive it into her.
As soon as she was upstairs they french kissed and removed all their
clothes. Mary's pussy was almost dripping.


"Should I feel guilty taking advantage of you in this state?" Mike
asked his left hand creeping under her arse and groping for pussy.
"Yes you should be " she said in a mock school maam accent, and then
she closed her eyes and sighed, squeezing her body against his, feeling
his erection pressing onto her naked tummy "and yes you should, take
advantage..." she murmured as she took her left hand down to his
penis, and idly wanked it. Mikes hand reached around a little further
and he pressed a finger into her. He removed it slowly and pushed her
down onto the bed.

He did not waste any time and gently nuzzled his penis against her
snatch. It smelt of sexual excitement and spunk. It slipped in very
easily. Again this to Mary felt incredible, far better then it had ever
felt before. Involuntarily she was holding her breath, it was so nice,
and then out of nowhere and orgasm built up taking her by surprise. She
felt her vagina spasming, "Oh God thats incredible MIKE MIKE
AHHHHHH" she shouted. Mike was a little take by surprise but gently
thrust in and out of her waiting for her to recover. When she did a
little he kissed her mouth and then started a long lazy stroke. Mary
felt a deep throbbing pleasure not exactly in her vagina but a feeling
in her lower body that could only be described by a metaphor of a white
light of pleasure waving through her. She placed her arms around his
neck and squirmed with pleasure as he gently pumped in and out. Gently
he speeded up and asked Mary if he should come. She was too far gone to
answer. She just pushed back against him. He tried to slow down to allow
himself to not come and be able to carry on for a few minutes, but Mary
was rocking and squirming around and stimulating him to much. For the
second time that day Mike squirted deep into Marys beautiful plump young
body, crying out with an "AHHHHHHhhhhhhhhhhhhh" as he did so.
After coming he left the penis in and moved very gently in her. They
made love three more times that night and then he fell asleep. Mary
masturbated next to her exhausted sleeping lover before falling asleep
herself, a wet patch of their combined love juices leaking out of her
pussy and staining the sheets as they slept.

The next morning, waking up next to Mike, she felt a little stupid. She
woke him up, getting dressed and told him not to get used to it. She
remembered her ovulation cycle calculations, and sighed with relief.

The next day in the lab it was all smiles and grins. Everybody knew what
had happened and Mary slightly suspected Mandy of seeing them screwing
on the floor of the video room. Sophia, a Swedish research student, came
over to her at coffee break, and asked if it was true that she had taken
DH265. She was a natural blonde with corresponding thin yellow hair. She
had very pale scandinavian features, even her eyes almost a washed out
grey blue. She wore jeans and a loose cotton wrap around top. She was
thin and had nice pert boobies, and a nice curvy waist. It appeared some
people thought Mary had taken it deliberately. Mary said "yes but by
accident, I spilled some on my blouse, and it must have got in through
my skin, I think I took a very large dose", and then described what it
did and how good it felt, but also how careless she had been. The pupils
in sophias blue eyes widened a little.

"You shagged someone in the lab then?" she asked. She pronounced
"shagged" with a slightly long vowel for the first 'a' and in the
manner that it was the correct verb for sexual intercourse, which made
it sound a little silly.
"you try it" Mary said quietly, "makes the boys look a whole lot
better too. And those female mice we have been experimenting on, I can
tell why they flip their heads about while copulating, they are in 7th
heaven lucky little things"
"I cannot do that, its against the laboratory guidlines" she said
flipping over to Scandinavian follow the rules robot mode.
"spill a few ml's of concentrate on your skin then" Mary laughed.
Sophia was unsure whether to take her seriously or not. English
university students were a bit strange she thought. After all half of
them even smoked pot, and that was illegal even in this lax country.

During the working day, Mike kept a little distance from Mary, but at
just after 11 am went over to her to ask her to report to Professor
Gerard. Smoothing down her skirt and her now two days worn tights, she
walked through the campus and past the book shop to his office. Her
vagina was pleasantly sore from the previous days romping, and she felt
that there was a lingering aftershock of the drug. Almost as though a
door to intense sexual pleasure had been opened. She passed through the
office doors and went up to the professors office.

She knocked on the door, even though she could see the silhouette of the
professor sitting alone in his room through the frosted glass. "Come
in" he cheerily called.
She went in and sat down smoothing her skirt as she did so.
There was a small pause and then Proffessor Gerard coughed and spoke
"Did you have a accident with the DH265 yesterday Mary?" he asked
softly.
"Err yes I spilt a little concentrate on my blouse. I think weight for
weight I must have had at least double dosage"
"OK, I heard some rumours, but no stress, first thing are you OK?"
"Yes, fine"
"OK, did it make you feel any different ?"
Mary grinned a little, put a poker face on and then said "Oh yes, that
stuff works, but its quite intense, I would not think it was safe to
drive a car on it, AND it seriously alters your judgement, I mean..."
"OK, I don't want to pry, lets just say you are our first
unintentional guinea pig then. We'd better get you medically checked and
have some blood tests taken to see how much is still in your system"
Mary grinned and adjusted her seating position. Her luscious thighs were
encased in the two day old tights. She had washed her kinckers quickly
in a sink and left them to dry but they were still stained and a little
crusty! She thought to herself how excellent it was to be a chemically
induced bitch on heat and how good it felt. Looking back on that state
of mind there was a freedom in being fully sexually uninhibited, but
there was also a little embarrassment. The professor must have known
what she and Mike had done, and it was obvious to her, that Mike must
have had a chat with him just before her. This drug, she thought, was
almost like taking all your sexual morals and wrapping them around a
brick and throwing them out of the window. The rest of the conversation
was about trialling and a little clarification of the statistical fits
on the effectiveness.


Mary walked back to the lab feeling happy. She had, after all the key to
sexual fulfilment the like of which she had never experienced before, in
a bottle. A drug cocktail she had helped develop. Deep down she knew it
would only be a matter of time before she dosed herself with it again.
But this time she, thought, I'll plan the venue and the man (or men...
Mike had been good but she had had to do herself once after he had
fallen asleep) ! She wondered if the drug was still affecting her, or if
she had been changed for ever. She decided she did not care either way.
