The young intern knew it would be days before the head of her department would be back. They still had one moon stopover before they arrived at the planet he was doing his studies on, and Desiree had the lab to herself.

The exam table made a perfect place to play, and she had gradually stretched her slit wider and wider, using larger and larger test tubes to fuck herself. They had a nice blunt end and slid inside so perfectly, it had been easy to force herself open, enjoying the tight, stretching sensations and becoming excited by the thought of being able to take in bigger and bigger toys.

She carefully selected a thick test tube a little over five centimeters in diameter, and slipped her panties down under her skirt to allow access. She shuddered and moaned softly, feeling the cool glass penetrate and push her wide apart. In her mind she imagined an alien creature entering her tunnel, and orgasmed quickly. Desiree wasn’t satisfied, however. Tonight she was feeling particularly lonely, and wanted more.

Having worked at the lab for over two years now, she had become familiar with a variety of different specimens being held for study aboard the ship. Particularly intriguing were the Lingus worms, discovered on Lingus 8 just a few months ago. They were chameleons, so at the moment they were a creamy white to echo the stark lighting in the lab. She watched their rubbery bodies slowly twist around each other in the zero-grav tank, each one the size of a large Earth nightcrawler. The Lingus worm head had two black pinprick eyes and a sucking, rasping mouth like a snail’s for scraping into its food. In the two months they had examined the Lingus worms, they found that they would eat just about anything. Whenever Desiree looked at them, she could feel herself becoming slippery, her pussy twitching gently of its own free will. She had become a bit of a xenophile over the past two years.

Looking around (as if anyone would be in the lab in the middle of the night), she deactivated the zero-grav tank and slipped three of the worms into the glass test tube, then capped it tightly. She turned the tank back on and then looked at her captives for a few seconds before retiring to the exam table once again.

She watched herself as she slid the worm-filled dong back inside her pussy, gasping with pleasure. Desiree laid back and pictured the worms entering her as she manipulated her clit and slid the cool glass tube in and out of her cunt. It took a little longer to cum the second time around, but the thought of these alien creatures inside her finally sent her over the top. Hips arching, she gasped loudly as she shoved the tube as far inside as it would go, then sighed as she finally sank down onto the table, holding the glass toy in place.

"Having Fun, Ms. Cox?"

Squealing with surprise, Desiree sat bolt upright and whipped the tube out of herself, trying to close her legs and hide the toy all at the same time.

Her boss had come back early.

The lab had no windows, and she had not realized that they had passed the moon stop and gone straight on to Lux Maytii because of a minor medical emergency with one of the research team members. Her cheeks grew hot as she tried to produce a response.

Dr. Curtis tried to look angry, but she noticed a bit of a bulge to his pants. Realizing where she was looking, he cleared his throat and turned his back.

"Recover yourself Ms. Cox, then we shall talk about your trip to the brig."

She scrambled to put her underwear back on and then went to dump the worms back into the tank. But the worms were gone.

"Holy shit..." she murmured. Then, looking around furiously and looking under the layers of fabric on the exam table, she exclaimed loudly, "Holy SHIT!"

"Something wrong, Ms. Cox?"

Dr. Curtis had turned back around to see the frantic young woman looking for something, a growing look of panic on her face.

"They’re gone... the Lingus worms..."

"What are you ta..." then Dr. Curtis froze, a cold feeling running down his spine. "Were they in that test tube?"

Unable to bring herself to look at him, Desiree nodded at the floor. Dr. Curtis grabbed the tube from her hand and examined it. Still sealed tightly, covered with Desiree’s vaginal juices, the worms were indeed missing.

"You fucking IDIOT!" he shouted at her, "Didn’t you read the instructions I left? Don’t you understand why they’re in zero-grav??"

"Well sure," she said quietly, "but they were sealed..."

"No time to discuss this!" He shoved her onto the exam table and roughly stuck two fingers into her slit. "Nothing... wait... WAIT... DAMMIT...!" He shoved his fingers as far inside her as he could, but it wasn’t enough — he could just feel the tail end of the last worm slip inside her cervix.

"OW! Shit! You’re fucking killing me!" screamed Desiree as she tried to shove him away, then saw the look of dread on Dr. Curtis’ face. "What...? What’s wrong...?"

"They can travel through any liquid, Ms. Cox. ANY LIQUID. And what, if we may review your obviously lacking high school chemistry class, is GLASS?"

"It’s... it’s a..." her eyes flew open in shock and horror. "Wh... where... are...?"

"Apparently they like the taste of your womb, Ms. Cox."

Shivering now, Desiree sat up and hugged her knees, unsure what to do next. But Dr. Curtis had already gone across the room and retrieved the portable internal imaging device. Flipping on the overhead monitor, he motioned for her to lay back down, then began slowly sliding the hand-held box over her lower abdomen. After making a few adjustments, a perfect living image of her uterus appeared on the screen. Three worms were inside, exploring it happily, now bright pinkish-red to match the color of her womb.

Resisting the urge to vomit, Desiree could not stop watching the screen. Dr. Curtis was saying something to her, but she was fascinated and didn’t hear him. Three alien life forms were inside her body at this very moment... one of them thrashed particularly violently and she felt a very slight flutter from deep inside herself.

"Oh my god...!" they said together.

Dr. Curtis had stopped lecturing her and zoomed in on the head of one of the worms. It had its mouthparts on the wall of her womb and looked like it was nursing.

"Holy shit, is it eating me...??" squealed Desiree in terror, starting to shake again.

"Hold still, dammit... no, it’s... it’s not..." Dr. Curtis looked confused and fascinated. "I’m not sure what it’s doing... look!" Another one is latching on now..."

His scientific mind had taken over and he was absolutely riveted by the scene. Desiree’s revulsion and shock had subsided, and she was also becoming entranced once again by what she was watching. The third worm found a hold and began suckling on the lining of her womb.

Zooming in further on the first worm’s mouthparts, they could both see that it was not eating her at all. It was just... sitting there, firmly attached.

Desiree finally broke the silence. "Uh... now what...?"

"I have no idea..."

"Do we... do they have to be removed...?" She tried to sound noncommittal, but Dr. Curtis picked up on her tone.

"Do you want them removed...?"

"I... I don’t know... if..."

He studied her face, looked at the moving images on the screen, then said, "This IS a scientific lab, you know."

She looked down at her belly, saddened. "I know.... I hope the procedure... won’t..."

He cut her off. "We COULD just observe them for a while."

The silence was long and thick. Seconds became minutes. Finally, Desiree nodded and allowed a tiny smile, a myriad of thoughts passing through her mind.

"Of course, you’ll have to stay here while we observe them. In case anything goes wrong, you know." Dr. Curtis looked at his intern with a new respect, almost awe. "This is one hell of an experiment, Ms. Cox."

Her smile broadening, she nodded again silently, then went back to watching the screen.

Several days later, she had been moved into a more private cubicle inside the lab, a video monitor strapped to her belly, recording everything the worms did. She could feel more flutters now, and watched her tiny alien children grow larger as they nursed on the blood-rich lining of her womb. Dr. Curtis visited her every few hours, and each day she had to record any changes in the creatures as well as the movements she felt.

In two weeks the worms had tripled in size, and they estimated that each one was now two centimeters in diameter and almost a meter long. Desiree clearly felt them writhing inside, and she noticed that even Dr. Curtis was starting to become more than scientifically interested — she sometimes caught sight of an exciting bulge in his slacks in just the right place.

Soon she was requesting more food and her belly began to expand softly, requiring her to wear looser dresses. Another week went by and the worms were even larger, feeding from her womb and wrestling with each other.

Laying down one evening, she took off the monitor and pressed her hand into her abdomen, gasping as she felt the creatures sliding under her fingertips. Of course she could feel them moving inside her body all the time, but feeling them this way, as if she were carrying a human baby, made her excited anew.

"Desiree, I came in to see why the monitor..." Dr. Curtis stopped short and watched her feel the new life in her enlarging belly, then pressed his own hand down on her.

He turned around, closed the door and pressed the button marked "No Entry — Exam in Progress." Again, he felt her deeply, gasping in surprise and wonder at what he was feeling under his hand.

"Does it always feel like this... inside...?"

"Oh yes... I just wanted to see if I could feel them moving from the front, seeing as they’re pushing me out like I’m pregnant."

"You are, you know."

They both caressed her swollen abdomen, feeling the growing life within. Then he kissed her pregnant belly, softly and tenderly.

He turned to leave again, an obvious erection in his slacks, when Desiree said "Stay..."

Turning around slowly, he simply stared at her as she slipped off her underwear. "I’m lonely..." she whispered.

Without a word he removed his shoes, then his lab coat, then his slacks, then his underwear. She smiled when she saw the size of him, and spread her legs wide.

Quickly he was on top of her, kissing her belly, then licking her wet slit. Neither of them could wait — she whimpered and he pushed her legs upward, then penetrated. They both moaned as he thrust his cock in and out of her pussy.

"Oh Desiree," he moaned as he gave a final push and then shot a large load of cum into her grasping cunt. She rose up to meet him, grinding their hips together as she too orgasmed.

Then she gasped, her eyes opening in surprise. "They’re going crazy!"

Visible on the surface of her swollen belly were the wild gyrations of the worms as they reacted to his cum. Quickly, he strapped the monitor back in place and adjusted it, expecting to see the worst. Instead, the worms appeared to be drawing the fluid inside their bodies through tiny pores all along their sides. They fought over the new food, and seemed to grow larger before the eyes of the astonished scientists. A new measurement at the end of the day confirmed that yes, they had increased in size by 12% after his ejaculation.

Unsure of what it could mean, the couple resisted having sex for a few days, then, after measuring the size of the creatures, fucked again. Sure enough, they again thrashed around wildly, drinking his cum as quickly as they could. And again, they grew larger almost immediately. Desiree could feel her belly stretching, making her excited and almost constantly stimulated.

A few more weeks passed, and Desiree now proudly caressed a pregnant abdomen the size of a woman seven months along. She began to wonder how much larger they would become, and stopped fucking Marcus (she hadn’t called him Dr. Curtis in weeks) in favor of various toys.

"Where is this experiment going to end up?" She mused to him one day as he took yet another scan of her belly. He noticed that she sounded a little nervous, and patted her huge, writhing womb. "We can remove them any time you want, love," he replied softly. But she refused. "Not just yet. I... I want to get bigger." He turned to see a large smile on her face, and dropped his slacks.

"That can be arranged," he cooed as he penetrated her once again. As soon as they had finished and he had shot a huge amount of jizz from his cock, they thrashed and grew larger once again, Desiree gasping from the almost overwhelming sensations. Marcus closed his eyes as he laid both of his strong hands across her moving belly, concentrating on the feeling below them.

"Your skin is so tight and shiny," he commented softly when he opened his eyes again.

Desiree purred and smiled. "God, I know. It feels SO good."

"You’re so beautiful..." Marcus kissed her belly, then began nursing on her breasts gently.

"Oh, that feels so... uh... my tits... oh, suck them... they feel strange..."

He nursed a little harder, then grunted in surprise as a new taste entered his mouth. He suckled, then began to drink her milk, swallowing each mouthful as if he hadn’t eaten in weeks. She fondled her other breast, then whispered "milk..." as she felt the moisture between her fingertips, the strange new sensation of it flowing through her ducts and out her nipples exciting her. Marcus took the other nipple and drank deeply, the heavy, tingling, shifting feeling inside her breasts as she let down her milk causing Desiree to sigh with contentment and wonder.

They couldn’t help it — soon he was pushing his shaft deep into her tunnel once again, and it didn’t take either of them long to cum. Again, the creatures in her womb whipped around madly, and she felt the skin on her belly tighten even further. Rubbing it without thinking, she sat up with some difficulty.

"Something.... something’s going on..."

Alarmed, Marcus looked at the monitor and saw the huge shapes moving much more slowly. Worried that they weren’t doing well, he refocused the scope and saw inside the bodies of the beasts.

"What are those...?"

They both peered at the screen, trying to understand what they were looking at. Then one of the worms began pushing its way past the others, its tail end matching up with Desiree’s cervix. She gasped, and Marcus turned to see that she wasn’t even looking at the monitor any longer. She was kneeling on the bed, holding her huge belly with both hands, mouth open.

"I... something... what’s happening...?"

Marcus turned toward the screen again, and saw the mysterious shapes inside the worms start to shift and move further down towards their tails. The two others were trying to get to Desiree’s cervix, but the first worm’s tail had already opened up and latched onto it like a French kiss. The large spherical form began to pass out of the worm’s body and force Desiree’s cervix apart.

"UGH! It’s cramping!!" Desiree began to pant and massage her belly faster as if it would help relieve the discomfort. "Something’s happening... I have to... I have to... push..."

Marcus watched in amazement as the baseball-sized orb passed through her cervix, then turned around to see his lover give birth to her first alien egg. She grunted and moaned, sweat beginning to bead on her forehead, as she forced the smooth, hard form between her stretching, reddened pussy lips. Shiny with the combined slime of her cunt and the worm’s body, Marcus held up the egg, its perfectly spherical form covered by a thick, hard, colorful shell.

Suddenly, Desiree grunted again loudly, and a second egg popped forth from between her widening labia. Thinking quickly, he used a nearby wash basin to collect the eggs, as one after another slowly issued from his lover’s womb. After seven eggs had been pushed out, the panting Desiree leaned back and rested. Marcus checked the monitor — the first worm had let go of her cervix and was much smaller... but as he watched, a second worm attached itself to her and began to slide the shapes downward.

"There’s more coming... that was only one of them."

Nodding, Desiree took a quick drink of water from her nightstand and got back up on her knees. As before, he watched the large spheres start to pass through her cervix, and she grunted behind him on the bed.

"Are you okay...?"

"YeahUHHHH..." she paused to push out an egg, then took some deep breaths. "Okay... doesn’t... UHHHH.... hurt now... just str.... UHHHHHGHHHH.... stretching... it’s good..." Another fist-sized egg popped out from between her legs. "Wish you could feel.... UHHHH.... making me hot for youOOOOO..... UHHH..." She smiled as another stretched her lips as wide open as they would go and then was deposited onto the bed. "Oh god this feels good... UHHH ANOTHERRRR....."

He watched the monitor again, saw the second worm detach from her after the final egg.

"Quick, get a drink now, the third one is about to start." Marcus collected the other six eggs and placed them with the first in their container. Desiree chugged some nutritional drink this time, which immediately made her feel much better. Then she felt another egg push its way out of her opened cervix.

Marcus watched her continue to give birth, this time holding her hand and dabbing sweat away from her reddened face. Rivulets of milk streamed down from her rounded breasts, and Marcus noticed that her belly looked somewhat smaller. Neither of them said anything as Desiree grunted and worked to push the eggs out. Finally, after another six eggs were forced from her slit, she collapsed backward, panting. Marcus kissed her gently on the cheek, then took the eggs and left her alone to rest.

After an hour or so, he came back into the room, waking up his love.

"Desiree, there’s something interesting. You’ll want to hear this."

She stirred from her nap and sat up, the familiar twisting sensation of the huge worms inside her much calmer than usual.

"Is everything okay? Are they still okay? They’re not moving much..."

"Yes, they’re fine. I’ve been watching them on the monitor, and I expect they’re as tired as you are," he chuckled. "Here’s the interesting thing. I took one of the eggs and scanned it, and... and... you won’t believe it..." he paused, shaking his head.

"What? What is it, dammit??"

"I... I scanned their genetic composition and only half of it is identical to a Lingus worm."

Desiree pondered what he was saying. "So... what’s... the other half...?"

Marcus shook his head again, then finally said, "It’s human."

She stared at him, wondering what it could mean. Then he spoke again as if to answer her unspoken questions.

"It’s... it’s mine...!"
