A sci-fi bookworm discovers the many pleasures of a different kind of worm

She was known for reading too much. At least, that’s
what the other kids at school said. She was the class
nerd, always delving whole-heartedly into biology class
while the others talked about the homecoming game and
flipped bits of dissected frog up into the light
fixtures. Naturally, she was not well-liked, but she
didn’t seem to notice too much — her world was on

Her favorite books were science fiction, and she must
have gone through two or three a week. “Gina,” said her
mother, “you need to socialize… to have fun and go on
dates at your age.” But Gina wasn’t interested. A late
bloomer, everyone said.

One night, after falling asleep reading her latest book
on aliens, she was awakened by a noise in her room. The
light was already on, so she blinked sleepily toward
where the noise had come from, but saw nothing. She
shrugged, thinking it was probably the cat or a bad
dream (she had them sometimes after a particularly
intense chapter), and turned off the light to go back
to sleep.

Her fingers wandered then, and in the darkness she
began sleepily exploring her newfound sexuality for the
fun of it. It was only a few weeks ago that she had
begun masturbating in earnest, experimenting with
various things around the room that could please her
more than her own wan fingers. Once she had even snuck
a carrot into her room, but she became worried that it
would be discovered and got rid of it the next morning.

Now, however, she sat up and mentally searched her room
for something to fill her vagina, settling on a small
bottle of lotion. She stifled a groan as she pushed it
in with her left hand and rhythmically massaged her
clit with her right, finally gaping silently into the
night as her back arched and she spasmodically shoved
the bottle as far inside as it would go, her tight
pussy muscles working themselves against the cool

She relaxed, and slowly withdrew the bottle as she
jolted a few more times. Ah, the perfect conclusion to
my climax, thought the bookworm as she smiled to
herself. In bliss, she rolled over to one side, kicked
the covers off, and fell peacefully to sleep. But she
was not alone in the room.

Only a short time later, she jerked awake, feeling
something touch her leg. Gina looked around, and not
seeing anything, rolled over again to go back to sleep.
Again she felt the soft touch, cool and fleeting, and
this time caught a glimpse of a dark shape retreat over
the side of her bed when she jumped reflexively.

Turning on the light, she saw the form dart under the
bed, but when she turned it off again, she was able to
make out something moving (slithering?) up the side of
the mattress. Pulling her knees up to her chest, she
watched carefully to see what it could be, thinking it
might be a snake. She was curious rather than
frightened, and examined the moving shape as best she
could in the dim moonlight coming from her window.

But it was not a snake. It was shiny, almost like an
eel, and left a slight trail behind it as it moved
toward her. A giant slug? Her mind worked as it inched
toward her, again touching her flesh. But it wasn’t
slimy to the touch, and as it approached, she could see
that its head was quite different than a slug’s. At the
front of its two-foot-long body was nothing but a
sucker, something like the mouth of an algae-eating
fish. There were no teeth in it, and as it explored her
right foot, it almost felt pleasant as it tasted and

She moved out her hand to touch it and it shrank back,
but this time it didn’t dive back off the bed. She
slowly touched its back, and it approached her again.
She relaxed, sitting cross-legged on the bed, and let
the thing work its way up her leg like a pet. She
continued stroking it, and it began to vibrate slightly
as if purring, but it made no noise. The shiny beast
inched closer to her body, occasionally lifting its
sucker into the air as if smelling for something, then
returning it to her skin to taste its way along.

Gina began to enjoy the sensation of it on her thigh,
and also began to notice that it was consistently
“sniffing” toward her freshly pleasured crotch. With a
tingle, she wondered what the creature could be, and at
the same time realized that it was nearly 2 inches
thick, slick with moisture, and seemed very interested
in her pussy.

She stopped the creature and picked it up, but it only
throbbed and vibrated complacently. The mesmerized
young woman held the buzzing beast in her hands, then
kicked the covers aside and laid down on her back.
Replacing it on her thigh, she propped her head up with
a pillow, deciding to see what it would do.

The creature took a moment to figure out where it was,
then crept toward Gina’s crotch once again, sniffing
and tasting. When it arrived at her pussy lips and
latched onto her clit for a moment, she gasped at the
new sucking sensation.

She had never felt anything like it! She spread her
legs, and the beast happily sucked its way around her
pink, exposed cunt. The inexperienced teen came
immediately, and to her amazement, the creature eagerly
suckled up her juices as fast as she could produce
them. She laid there in bliss for a moment, then felt a
new sensation.

The creature, having exhausted its supply of cum food,
began working its way inside her cunt. She could feel
its mouth working and pulling just on the inside of her
pussy lips, and she groaned with pleasure. This new
supply of juices seemed to stimulate the beast, which
began wriggling inside her more quickly and began
thrumming with pleasure. Naturally, this drove Gina
wild, and it was all she could do to stop herself from
cumming as she watched the strange, alien creature work
its way up inside her, vibrating the entire time.

Finally, she couldn’t stand it any more and had a
massive orgasm, shivering and straining hard to stay
silent. As she relaxed, she reached down to withdraw
her new friend. The creature had worked almost a full
foot of its length up into her cunt, and when she
pulled on the exposed portion, she found that it was
stuck fast. In fact, the more she tried to remove the
thing, the more it retracted its slippery body up into
her, making it harder and harder to grasp. She could
feel the sucker mouth firmly grip the back of her
tunnel as she pulled, and she finally gave up for fear
of injuring herself.

She sat up and felt the creature shift inside her, then
she stood up and went to the full-length mirror on her
closet door. She could see the very end of the beast
trailing out of her tunnel, about four inches worth,
and she began to examine her predicament. She crouched
down, spreading her legs to look at her pussy better,
and tried pulling it out again. No luck, and again, the
creature responded to the tugging by attempting to
retract itself further up out of harm’s way.

The wriggling, worm-like beast up inside her only
served to make her tingle, however, and it soon dawned
on her that she could have pleasure whenever she liked
if she treated the beast right. She stood and watched
herself in the mirror as she started stroking its cool
flesh (making sure to hit her own clit in the process),
and began to feel it vibrate with pleasure. This made
her feel even more pleasure, and she soon began to feel
it moving the sucking mouth around on her vaginal
walls, eating up every drop of lubricating juice she
was producing.

The combination of vibration and the wild sucking
inside her cunt made her cum again quite quickly, and
again when she tried to remove the animal from her
fuck-tunnel, found it was very firmly latched onto her
pussy flesh by its powerful mouth. Not quite knowing
what to do, but very happy at the same time, the tired
teen went back to bed, feeling the cool tail end of the
creature moving between her legs as she fell asleep
under the sheets.

By morning, Gina discovered, the beast had somehow
worked more of its huge, dark body up inside her, and
seeing that it didn’t show when she put on her clothes,
decided to leave it there until she could discover a
way to remove it. But did she really want to? Where had
it come from? And why was it so perfectly suited to
both please her and seemingly live off only
her pussy juices?

As she went through that Sunday, she avoided everyone
as much as possible. She told her mother that she was
working on a school project, and virtually locked
herself in her bedroom, only opening the door for
meals. As day turned to evening, she again tried to
remove the creature, but found it just as stuffed into
her pussy as ever. As soon as she began tugging and
handling it, it began to throb and vibrate again, so
she resigned herself to her bed for the next few hours
until finally falling asleep in a fulfilled haze.

She was jolted awake by another noise in her room… or
was it a noise? She had heard it in her head, but
sleepily wondered if she had actually heard anything at
all. Had she dreamed it, or was it another nighttime
visit from another creature? She sat up, felt her worm-
like companion roll and shift deliciously inside her
hole, and watched as the tip of its “tail” came out of
her about four inches to tickle her anus.

Before she could enjoy this latest sensation, she heard
another noise and looked up to see a small humanoid-
shaped creature standing at the foot of her bed. It was
glowing slightly, and before she could notice that the
beast in her cunt was glowing as well, everything went

Gina awoke in a large room with smooth, dark grey
walls. She had been strapped to a table spread-eagled,
but not so firmly that she couldn’t raise up on her
elbows and look around easily. She saw that her worm-
like companion was still in place, and that she was
totally naked. She shivered, only half from the cool
temperature of the room, and laid her head back down to
wonder what would happen to her next.

A short time later, a humanoid creature like the one
she had seen in her room came and stared at her, then
left and returned with two others. She could hear their
communications, although they did not open their slit-
like mouths, and with a shock she realized they must be
communicating telepathically. Soon one of the creatures
faced her, and began speaking to
the young woman in her own language.

“The experiment has been a success — you are but one
of many breeders that we have selected. The creature
that you allowed to enter your breeding tube is your
mate now, and is genetically engineered to both
pleasure you and synthesize your pleasure juices as
food. You will help your mate produce offspring, and it
will cause you no displeasure. Do you agree?”

What was she to say? Here she was, on what must be some
kind of alien ship, restrained in the most revealing
position possible, with her cunt full of some kind of
strange, sucking worm. She was probably dreaming
anyway. What else could happen?


“Good. We will keep you fed and happy for your
cooperation. What do you require?”

Not stopping to think about what the result would have
been if she had said no, Gina replied, “I’m a little
cold. I think my body temperature is higher than
yours,” she said, remembering the feeling of the cool
beast as it slipped deep within her pussy. “And do I
have to stay like this?” She tugged at he restraints
for emphasis.

“Excellent. We will provide you with your own domicile
and some body coverings. Come with us.”

The small beings surrounded her, and the one that had
“spoken” to her began walking down a corridor. She got
up from the table, and felt the worm try to contract up
inside her in response as she began walking. She could
feel the tail end of the fleshy creature rub between
her legs and finally curl around to touch her ass hole,
forcing her to waddle somewhat as she followed the
other creatures to her new home.

Soon she was reclining in a medium-sized room. It
contained a bed much like her own had been, a cabinet
with what looked to be some sort of clothing inside,
the usual toilet amenities, some devices that she could
not decipher, and a comfortable chair with a small
table attached. She found that all the clothing turned
out to be variations on a sort of shapeless dress, and
that one of the devices was some sort of food

One of the aliens returned (they all looked identical
to her). “Be comfortable. Your job is only beginning,
and you will be staying here a very long time. You are
to stimulate the creature inside you so that you obtain
pleasure and feed it. We will do what we can to keep
you pleased, since we have found that your kind
requires happiness and the lack of fear to feed our
creatures. We will bring you some of the bound paper
items you had so many of back on your planet to keep
you entertained. You have nothing to fear from us. We
will care for you until you cease, even when you are no
longer mobile.”

Before she could ask what it had meant by that last
statement, the door of her room slid shut with a hiss
and the being was gone. She shrugged to herself, and
after a time of pacing around the room decided to
fulfill her mission to these creatures. Laying down on
the bed, she began to stroke and even talk to the
creature that had invaded her hole so completely.

In only a short time it had throbbed and thrummed its
way to her orgasm, enhanced once again by the
incredible suckling of the mouth far up in the back of
her cunt. It was actually more exciting, knowing a bit
more of what it was doing and what was happening to
her. But the alien’s last sentence still puzzled her
and disturbed her a bit.

Gina brought herself pleasure with the worm as often as
she liked, and the beings seemed pleased with her
vigorous efforts. She kept asking what was meant by
“when I’m no longer mobile,” but was never given an
answer. However, judging from the way the worm inside
her was growing, she began to suspect what might be

Once she had used her nimble fingers to explore her
crammed pussy, expecting to be able to run them around
the edges of the worm, but she found that an odd change
had taken place. She only penetrated about an inch
before finding that a strong network of fibers had
grown from the creature into the very walls of her
vagina, connecting them together. She supposed that it
could be removed surgically, but suspected that the
aliens weren’t about to do that.

Over the next week or so (she had lost count of the
days), further explorations found that the worm had
neatly fused to her cunt lining, and she came to the
realization that it would most likely be inside her for
life. She had also noticed that the worm was still
growing, and now trailed out of her by a good 18″ at
all times.

She was grateful for the flowing dresses now, as any
kind of pants were out of the question. And still she
fulfilled her promise while fulfilling herself, knowing
that every time she came, the beast inside her would
feed and continue to grow.

Several weeks passed, and she was beginning to
understand what the alien had meant by “no longer
mobile.” The gigantic worm was now fully four feet long
and four inches in thickness, and she had difficulty
getting up from the bed due to its extra weight, let
alone walk around. She began to feel something new as
well — a small pushing against her cervix that grew
with each day. Finally, she was sure she could feel
some kind of extension from the worm penetrating her
uterus, which only served to excite her as she felt the
new vibrations.

Another week, and she was sure the creature had been
extending into her womb, and even began noticing small
nudges from within, visible as she stared at her naked
belly one day. She watched the bumps move across her,
just under her navel, and was only excited further.

The worm, which was now at least six feet long from the
tip of its tail to where it was connected to her cunt,
bulged to six inches in thickness just outside of her
former entrance (now an exit), and had developed a
habit of wriggling its tail around the room as if
exploring by touch. Once it had even raised her up by
her pussy, almost as if she were standing impaled
upright on some sort of great snake, but it seemed to
sense her fear and put her back on the bed again.

Still the worm continued to grow. And it began to emit
a small amount of pinkish slime from its tail end. The
pair was moved to a larger room, one with more space
for the worm to thrash about, and the aliens seemed
excited by the pinkish slime.

“You have done very well,” was all they would say. They
certainly kept her happy enough, and they had kept
their word that she would “receive no displeasure” —
all she had known for weeks was almost constant
pleasure from the muscular beast inside her body. She
could feel more and more of it filling her, and began
to see that her belly was enlarging.

She giggled a bit at the thought of being “pregnant
with an alien baby,” and while that was not really the
case, it did add a new dimension to her pleasures as
she reached orgasm and felt the marvelous thrumming all
the way up inside her swollen womb.

She soon discovered that she no longer had to stroke
the great worm when she wanted to be pleased — it
seemed to know what she wanted and when. So she began
experimenting with a new possibility. After a few days
Gina was able to command the beast to lift her up
gently by her pussy, thus gaining the ability to move
around at will once again. She simply wrapped her legs
around its thick, cool body and willed it to wriggle in
the direction she wanted to go. The aliens marveled at
her advanced progress.

“Excellent! But do not stress your creature at this
time. It is almost ready to breed.”

“I thought it was breeding with me now,” said its
confused female host.

“No, you are merely feeding it.”

As was their habit, the aliens left quickly after
speaking to and examining her, and as usual she was
left staring after them, unable to formulate a question
that fast. Soon afterward, to Gina’s amazement, another
young woman in the same circumstances as herself was
brought into her room. They stared at each other for a
short time, but soon their cunt-filling creatures had
sensed each other and the great moist tails began
creeping towards each other. They began to exude more
of the pinkish liquid and vibrate, giving both the
girls quite a thrill.

But at the same time, the excited worms began to squirm
and thrash, forcing both the humans to cling to each
other to avoid being injured. Soon, the worms wrapped
around each other and started exuding a thicker pink
mucus, coating the two writhing forms where they met.
The vibration continued, and one after the other, the
two girls came to climax while holding on to each

Somehow, in the haze of what was happening to them,
Gina and the other girl began holding each other very
closely, even wrapping their legs around each other
instead of the worms that were now holding them both
upright. They had long since found clothing
inconvenient once the temperatures of their rooms had
been adjusted to their liking, so the two hosts clung
together naked as their beasts vibrated, writhed, and
continued mating. At some point Gina was struck by how
similar it looked to the way earthworms mated, being
both sexes in one.

The mating continued for an hour, for two hours, for
days… who knew? And the female hosts, under the
constant, unrelenting stimulation, began to gently
touch and caress each other. Gina closed her eyes as
the other girl suckled her hardened nipples, and in
return Gina pressed the other teen’s head closer while
grasping a handful of her exposed ass and tracing the
outline of her enlarged pussy lips, so like Gina’s own.
She had long since abandoned any ideas about sexual
propriety, and this encounter seemed to be the most
natural thing in the world to the both of them by the
time it finally ended.

The worms finally disengaged from each other, having
fulfilled their fertilization, and their hosts
grudgingly let go of each other as well. In typical
fashion, the other girl was removed from Gina’s room
before they could even exchange names, and she was left
alone again with her constant companion.

A few more weeks passed, and the worm seemed to be
getting bigger, but only below the point where its
massive body was joined to hers. One evening (or was it
afternoon?), Gina discovered a new thrill from her
cunt-filling friend. As the beast’s body continued to
grow and bulge outward, she thought she saw what looked
like another small worm growing from the side of it,
just under her clit.

Her suspicions were confirmed one evening (or was it
afternoon?) as she began to masturbate — the smaller
worm now looked and acted just like the little one that
had first suckled its way inside her virgin cunt all
that time ago. She felt a familiar suckling mouth touch
her fingers, and with a pleased sigh, Gina simply
flopped backward as the little mouth went to work on
her clitoris. She came again and again, and all without
the need to use her hands even once.

What she hadn’t noticed was the small worm that was
beginning to form behind her. But soon enough, during
one of her many pleasure sessions with the huge beast
inside her, she felt a tentative suckling at her ass
hole. She was startled at first, but it felt so good
that she quickly warmed up to the new source of
excitement, rewarding her worm with a good meal of cum.
The worm, sensing her pleasure and encouragement, kept
vibrating and exploring, until soon the sucking mouth
began to enter her ass as well.

She was in too much ecstasy to protest or think about
what was happening. She felt the gentle, tentative
explorations of her ass, then came quickly as she felt
the worm invade her second entrance with more vigor. It
was suckling and pushing ever upward, vibrating to
pleasure her the whole way. The cool, black extension
slowly, gently writhed and pulsed its way several
inches up into her asshole, then stopped, never to
leave again.

This new source of pleasure drove Gina wild over the
next few days, and she kept her worm very well fed. The
other new sucking mouth had attached itself to her
clitoris, so all she had to do was lay back and imagine
what would please her most, and her beast did the rest.
Between the perfect suckling of her clit, the now
familiar stretching of her pussy walls, and the
vibratory exploration of her asshole, she was in an
almost constant state of pleasure as she felt the
creature’s cool body cradle her entire erogenous zone
from front to back like an enormous hand.

She began to wonder what had happened to her processes
of elimination, but when several days had gone by and
there seemed no danger of anything “backing up,” she
began to realize that the creature must have widened
its diet. The marvelous new finger of coolness
continued its upward travels inside her, until she was
no longer certain whether the erotic writhings she felt
were in her womb or elsewhere. And, true to form, the
small worm began to grow thicker, stretching her anus
ever so gently and deliciously. Gina felt so full, and
so wonderful!

Finally, after a few more weeks, the worm began to emit
a mucus and the aliens were in her room almost
immediately with large containers. In amazement, she
saw (and felt with a thrill) the worm’s muscular body
push masses of small globes about an inch in diameter
out of a previously unnoticed orifice near its tail
end. The aliens again seemed quite pleased as they
collected them, and Gina deduced that they must be
eggs. Again, the aliens were gone with their precious
cargo as quickly as they had come, answering no

Month after month, Gina and the worm kept each other
company. The huge black beast began to cradle her more
and more, slowly covering her ass and creeping up her
pubic hair. She began to discover that if she stroked
the creature just below their union, she could actually
feel the touch, and surmised that her bonded pussy
nerves must be extending into the worm itself.

Still it continued to grow, and the woman had long
since given up on sleeping in a bed, preferring instead
the cool, soft comfort provided by the immense body of
the creature connected to her by the tentacles inside
her cunt and ass hole. As the black flesh continued to
explore her, it eventually joined above her hips,
forming cool, soft, permanent “panties.” Of course, not
using her legs caused them to become weak, so she had
no objection when she noticed the beast begin to
envelop them as well.

Soon her legs were inside the beast, and after a few
weeks she could not feel them at all. But then a new
sensation crept into her consciousness. Just as the
nerves from her cunt had begun to merge with the flesh
of the creature inside her, the nerves that had served
her legs were doing the same. She soon discovered that
she could feel every movement made by the immense worm,
and was even able to control its movements herself. She
had become part of the beast, just as it had become
part of her, and for all practical purposes, they were
now one creature.

Her belly and holes were continuously stretched to
their limits by the incessant pushing of the worm
inside her, yet she was not unhappy. The huge creature
thrummed as it always had to bring her pleasure, only
now she was laying on an entire vibrating bed of dark
alien flesh instead of it just being limited to her

The monotony was broken up often by other worms and
their hosts mating with her and the great beast, many
of them smaller in size, most of them the age she had
been when her worm had mated for the first time. She
became an experienced hand for these younger girls, in
more ways than one, and was able to both calm and
excite even the most apprehensive ones.

She knew many of them were stunned by the massive size
of her creature, the fact that her legs had
disappeared, and by her hugely swollen belly. This
stretching never caused her pain, only pleasure, since
the psychic bond between her and her worm let the beast
know when it was pushing too fast. So over the years it
had enlarged her willing flesh and invaded her body to
previously unknown dimensions.

She could not be sure, but she guessed that it had
penetrated every non-vital opening available, and was
probably now happily growing past her open-ended
fallopian tubes, up into her intestines, and perhaps
even other openings covered by the glossy black body.
But she didn’t care — she felt only pleasure, just as
the aliens had promised.

In fact, the idea that her body was slowly being taken
over by this massive alien creature actually caused her
more pleasure. It was sort of like the science fiction
books she used to read, and the thrill of becoming a
new life form (especially such a sexual one) gave her
pleasure in many ways.

Within a few years, the constant stimulation had caused
her breasts to begin producing small amounts of milk.
The creature, searching out this new source of food,
crept upward and covered her belly, two new tiny worms
forming from its flesh and attaching themselves to her
sensitive nipples. With the added stimulation, her
breasts grew heavy with milk and both animals (or were
they one by now?) were greatly satisfied. The dark,
cool flesh now completely enveloped her body from her
breasts down to… wherever she ended and the worm

She never did determine where that was, especially
since she had become skilled at moving about. They
looked like a great black snake with a human head and
torso, and she could feel everything — the cool floor
underneath her, her hair as it brushed the end of her
tail. And she considered it her tail, just as she
considered the eggs the aliens collected to be hers.
After all, she could now feel the whole process happen
within her new body.

Gina knew that someday she would no longer be able to
feed her beast and they both would die together, but
the happy woman didn’t think of that very often. She
had other, more stimulating business to take care of.
And the door to her room slid open once again.
