It was a bright and sunny day, just the perfect conditions for swimming. Sarah knew just the spot and talked Rachel into going with her, as well as two other friends.

Sarah sat in the driver's seat. She had raven hair done up in a ponytail and dark skin. She was one of the shorter members of the group, and one of the cuter ones too, but was quite proud of her large breasts regardless.

The short-haired brunette in the passenger seat was named Jenifer. She was also quite busty herself

Rachel sat in the back and had long blond hair and light skin. Today, she needed to work on her tan.

Gwen, the tan woman sitting next to Rachel, had wavy lime-colored hair. She had quite a fetching pair of legs, which her miniskirt showed off.

"Sarah, you said this was a female-only nude beach, right?" Rachel asked.

Sarah giggled. "Yes, that's right.”

“Good. The last thing we need is a bunch of men perving on us the whole time.”

Sarah nodded in agreement. “We can get rid of those annoying tan lines without a single guy to bother us. The whole of the beach is fenced off too, so we won't even have to worry about anyone with binoculars."

Gwen smiled and put her hand on Rachel's shoulder. "I've been there a few times. The fence is solid and far too tall for them to climb trees and sneak a peek. Not that there are any trees that close to begin with."

"Well then, cool beans. And it would be nice to just get a full-over tan. Haha." Even with her swimsuit top, Rachel’s nipples could be seen through them.

Sarah pulled her convertible into the parking lot, already filled with a number of cars, and pulled into the first empty spot she could see. "Here we are, girls. Grab your bags and let's go." She paused for a moment to raise the roof.

"Now we can get naked." Gwen smiled as she pulled away from Rachel. She grabbed her beach bag and stepped out of the car.

Jenifer got out of the passenger seat. "Keep your shirt on, we aren't inside yet."

Closeby was a small building with a tall concrete fence running along either side. The building had one large door facing the front and a woman sitting behind the window next to it, a mindlessly happy look on her face. Also closeby was a sign that read "Clothing Optional Beach: Women Only."

"Wow, this is some tight security, huh? I'm waiting to see if the guards here are as bad as Fort Knox security." Rachel chuckled as she got out as well. It was strange that there were all these cars, but no sound of any woman inside.

Jenifer led the way and walked up to the smiling woman. "Four please."

The woman blinked for a moment. "Oh, sure. Go right in."

"Don't we need to pay first?" Jenifer held onto her wallet.

"Oh, right, we normally do that, don't we?" The woman giggled. "Sure, two dollars today. So two dollars for four girls is... eight dollars."

Jenifer rolled her eyes and pulled out a $10 bill. "Here’s ten, that's two dollars change."

"Right." The woman smiled and gave Jenifer her $2.

The changing room was just beyond the door. It was a normal looking but small beach house locker room. A wall of lockers were on one side, while a set of bathroom stalls ran along the other. In the middle were benches to sit on.

Gwen entered first. She wasted little time in stripping off her tube top and miniskirt. "Do you think that woman would’ve let us in for free if you didn't say anything?"

Rachel took her swimming top off, which made her breasts bounce a bit and expose her pink nipples to the air. "To be 100% honest with you, something about her didn’t make sense. Like, she seemed not really there while she talked to us. Strange." Rachel removed her skirt and panties, exposing her bald little pussy to the air. "Really odd."

Gwen's large breasts bounced around as she turned. "I know. Weird, right?"

"Well, no need to let it spoil our fun." Sarah pulled off her pink top, letting her braless breasts bounce free. She then slid down her white shorts, exposing her bare butt and shaved vulva.

Jenifer pulled off her skirt and stockings, revealing her neatly trimmed bush. "I remember them being more professional last time." She pulled off her sports bra.

Gwen stuffed her things into her bag. "Even so, it's time to have some naked fun. I don't see why we need to worry about her." She picked up her bag and headed to the other door.

The other side was a wide open space looking over the calm ocean. To the side of the door were a couple of open-air showerheads. Two volleyball nets were set up in the sand not far away. It was also very quiet; they could still hear the waves crashing, but they could no longer make out the muffled sounds of traffic that should have still been audible on the other side of the concrete wall.

The beach itself was fairly empty. Empty of people anyway, there was a bit of a mess regardless. Only six other girls were present in this fenced off mile-long stretch of sand and water. Two were splashing in the water, while the next pair were playing Frisbee, and the last two were laying on their beach towels, soaking up some sun.

Gwen blinked. "Weird. There were a lot more girls last time."

"Yeah, and there are a bunch of beach towels. Like, what girl would leave her towel behind? Not even counting the fact there’s a bunch of them. Maybe a storm broke and they split." Next to some towels were multiple globs of strange goo resting atop the sand. Some of it was pink, while the rest was purple. "Well now what? I don't care if they split, that means the beach is ours, ladies!” Rachel chuckled softly. “I’m gonna go find a spot to tan my fine ass."

"Have fun. I think I’ll warm up in the sun before taking a dip." Sarah set up her towel and bag in the sun before walking off.

"I’ll get in on the splashing." Gwen left her towel in her bag and set it next to Sarah's stuff, heading over to the pair already in the water.

"They really need to clean this place up." Jenifer sighed. "They certainly could do with better staff." She set up her towel and walked off, enjoying the feel of the sand between her toes.

"I agree. Okay, gonna soak up the sun while you girls go have fun. Wake me up in 30 minutes," Rachel requested before lying back and closing her eyes.

"Sure thing." Sarah waved.

"Don't let yourself get sunburned," Jenifer warned.

Rachel drifted off as she lay in the sun. It felt so warm and relaxing. However, it was not to last. She wasn't sure how long she was napping before a scream jolted her awake. She slowly got up and looked over at the source of the noise.

A group of two-foot tall people dressed in what looked like hazmat suits and gas masks had arrived on the beach. Each had four purple spots on their backs and held some kind of tool that looked like an oversized suction cup on the end of metal pipes, which had a tube leading to their backs. One had shot off and attached itself to Jenifer's face, as another did the same to a blue haired woman who was playing Frisbee before.

The two women struggled to remove the suction cups, but to no avail. Slowly, their skin became shiny and smooth as they started to flatten. At the same time, a purple spot on each of their assailant's backs inflated as if it were a long balloon, in spite of looking more like glass than rubber, filling up with a strange purple liquid as it continually expanded.

One of the other women ran to their aid, but before she could make it, a suction cup shot off from another pipe and attached itself to her face. She let out a muffled cry as she attempted to pull it off just as the other two.

At first, the girls panicked as the changes spread across their bodies, but before long, the fearful cries shifted to moans of pleasure. Rachel looked in shock as she saw one of their bodies making strange pulsating motions, like a boob being pumped by a milking machine. She let out a gasp and covered her mouth. "What in the world!?"

"Open up. Let us in!" One of the sunbathers had gone over to the changing room. However, the steel shutters had already closed before anyone had noticed. The woman started to bang on the metal barrier, her friend soon following.

A second group of short attackers had arrived from the other side. They had their suckers attached to a pair of women who must have arrived after Rachel had closed her eyes. The pair of nude women were slowly becoming shiny as they deflated, muffed screams turning to moans.

The first group soon detached their suckers from Jenifer and the blue haired woman. The two were now completely flat, their lips spread in an O shape as they laid on the sandy ground. They then moved onto another pair of girls who tried to run. Before long, the process started all over again, another purple glass bulb on their backs beginning to grow.

"Oh my god! They're killing my friends!" Rachel went over to kick one of the ones that got to her remaining friends. "Let them go right now!!"

The little guy jumped out of the way. He dragged Sarah along as he retreated, her body still deflating.

Soon, Gwen was the only one of Rachel's friends left. She charged the frogmen, her long green hair waving back as she ran. However, she was soon met with another suction cup to the face. She struggled and tried to pull back.

Very quickly, Rachel noticed something, Gwen's pussy started to drip wet and then her whole body started pulsating during the suction process, the shine washing over her skin. "Oh god, Gwen nooo!!"

Gwen moaned behind the cup. She slowly stepped back. Her nipples hardened as she grew weak. After a moment, she grabbed her breasts before she fell to her knees, her body slowly deflating.

Two other intruders walked up slowly behind Rachel. Several of their bulbs were full, but they each had one or two left.

Rachel had to admit that seeing this happen to Gwen made her turned on. "This is so wrong… But looks so hot…" Her tan limbs went limp as her skin became shinny and empty, with the same pumping motion on her body.

One of the little guys walked in front of Rachel. As Gwen fell to the ground, Rachel's face was covered with the red suction cup, trapping her in darkness. A tube forced its way into her mouth, and then started sucking.

She quickly felt her lips being pulled into an O-ring mold around the nozzle end, and then felt them vibrating against it. "Mmppphhh!" Rachel start to feel like she had to pee and cum at the same time, her nipples tingling too.

A small rubber hand grabbed Rachel's butt and stroked it. Slowly, she felt the change wash over her body. Slowly, the fingers brushed against her dripping labia, but soon pulled back.

Before long, Rachel could no longer stand. She fell to the ground as she deflated. Only once she was completely drained did the red cup pull away, leaving her rubber body to face the sky.

Rachel's mind, on the other hand felt herself pulled through a tight and long space. She soon saw the light as she found herself on the back of her attacker. She now felt so contained and squished up, feeling glass all around her, but was like a rubbery sort of glass. "Definitely alien tech." She wasn't able to talk, just able to see her deflated rubber body in the sun.

The masked invaders had won. No girl remained standing. Soon, another one of them picked up Rachel's rubberized body with what looked like a fishing rod. He pulled her husk up and then lowered it into some strange metal case. She was then folded up and locked inside.

As she was carried around on the bizarre creature's back, she saw the other girls being folded up and locked away as well. Next to her was another full glass bulb filled with the purple liquid. It swished around and took shape. It was almost as if it had a face.

Soon, all the women were boxed up. The mysterious beings carried the boxes and walked into the water. As they left, the shutters opened.

Rachel caught that as they left. "I had a feeling the woman in the front was acting strangely. Now it all makes sense, she’s working for these things!"

They submerged under the water and walked along the floor. After a while, they came upon a submerged ship. It wasn't very deep, and didn't look like any ship Rachel had seen before. The group entered an air lock and passed through some sort of energy field. The other side was dry, the water held back by the field.

The group walked down the hallway. Soon, they placed the boxes on conveyor belts and watched them roll away.

"Noooo, my body. I will miss you, we had so much fun together. So what are they going to do with us at this point? I mean, there had to be a reason for it." Rachel wondered as her captor started moving again.

They walked to another room. There, they attached their tubes to another machine. One by one, they drained their bulbs. Soon Rachel started to spin around and was flushed down a pipe. She then found herself in another glass tube, this time part of a line of them, all filled with the purple liquid. The one right next to her reminded her of Gwen.

"Gwen, is that you? Can you even hear me!?"

The Gwen liquid moved around in her tube. It seemed she was trying to say something, but Rachel couldn't hear her.

Over the next few hours, the short attackers made their occasional return. They pumped out more liquid into the machine, filling more tubes. There were many tubes in this room, and several dozen of them were already filled.

After a while, they rolled in a large glass chamber on wheels. Inside was the woman from the window, smiling mindlessly as before. She was locked into a metal alcove, clamps holding it in place, but didn’t appear to mind. She pressed her hands against the glass, looking around as some green energy washed over her. She then started to moan and massage her breasts.

"What the hell are they doing?" Rachel could hear other moans too, all across the room. She swore she could hear some feminine moos in there, which confused her further.

Rachel waited a few days trapped in that cylinder. Without any sunlight, it was hard to tell the passage of time. Still, it seemed they brought in the woman at night for her to sleep. While the green light washed over her, she would moan and play with herself. In the morning, they would clean and dress her before wheeling her out.

However, one day, they wheeled her into a different spot. A red suction cup lowered into her glass chamber, and then a voice sounded. "Press it against your face." The woman moaned and nodded. She grabbed the cup and pressed it against her face with glee. She then massaged her breasts and played with her crotch as the shine spread over her body. Soon. she started to deflate, the purple liquid sucking her into another holding tube like the others.

"What are they doing to her? No wonder she was so strange, they're using her as a toy, it seems."

The woman was reduced to nothing more than a latex husk. After folding her up, they opened the case and stored her away.

Once everyone was gone, Rachel felt the room shake. Everyone sloshed around in their tubes, the sensation lasting for quite some time. Then, they felt weightless for a moment, slowly rising up before gravity returned.

Later, the aliens returned and started taking away some of the tubes of purple liquid girls, fitting them one at a time into a new machine. Something odd happened to the group of tubes as a chemical was injected into them.

Rachel mentally moaned. "It's now making my liquid pussy all tingly like I’m getting wet, but that cannot be in this form. Mmmmm, I’m starting to feel horny..."

They took Rachel and Gwen into another room as well. Lying on a number of metal tables were the rubber husks they had picked up off the beach. Rachel soon found her own body, or what was left of it. Closeby were Gwen's remains. Rachel was soon put into a small machine, which was then hooked up to a tube that was placed in her rubber mouth.

Rachel started to drain, spinning around her container, flowing into her own mouth. Soon, she washed out into the hollow body and started to inflate.

Rachel's eyes opened as she took a deep gasp of the strange air, exhaling softly. "It’s been so long since I breathed with my own lungs again."

Soon, Rachel was fully inflated but still shiny, still made of some kind of latex. She was a bit stiff and it was hard for her to move. The little men grabbed her and pulled her off the table.

Gwen and many of the other women were also restored, but remained living dolls as well.

"Wh... What are you going to do with us!?" Rachel asked with a stammer. "I want to go back home. I want to watch Hell's Kitchen again..." As soon as she fell silent and relaxed, her mouth returned to an O shape.

"You are what you call cattle. You are going to feed the Gromos." The little man rubbed her rubbery body. His fingers found their way into her pussy, which was now in an O shape just like her mouth.

She could feel the wetness inside and how thick the rim was, like they designed it to be. She tried to tighten her pussy when she felt its finger go inside her, but no matter what, it was stuck open like that. "Wait… Cattle!? You mean like burgers and such, because I would rather be eaten whole and not cooked if I had a choice then."

"We are not going to turn you into “burgers”. You have been selected for milking." They pulled Rachel down onto the floor, holding her so she was on all fours.

"Milking!? No way, I’ve never even been pregnant, I don't have breast milk!" Rachel shouted.

Then one of them got behind her. "I will test this one out." He opened his pants, what passed for his penis pressing against her rubberized pussy.

Rachel look back, seeing a strange, huge dick. "No no nooooooooooo sooo big oooooh! I... I can now feel that inside my pussy! Ooooo, is rubber, ooooo!" Her womanhood was more sensitive than before. She could feel every inch of his member. It was thicker at the end than in the middle. He gripped her buttcheeks, squeezing them as he thrust deep into her.

Another one lowered his pants as well. He pressed his member against Rachel's rubber lips, holding her head and thrusting into her mouth.

"Mmpphhhh mrrrmm MOOFFM!" She tried to talk, but all her attempts did was make the owner of the dick in her mouth feel really good. Her rubber teeth pressed against it as her tongue was forced to swirl around the big, bulbous head. "Mmmppph!"

The man moaned, his gray cock thrusting deeper into Rachel's mouth. He certainly seemed to be enjoying himself.

Next to them, Gwen was on her back. Two more little men held her by her arms and legs as they thrust into her. She moaned as she was penetrated.

Even in rubber, Rachel's butthole pulsated from the pleasure as she rotated her hips to make his dick move around inside her pussy. "Mmmmmmmmmmmooommm!"

The Gromos moaned as well. Salty cum shot into Rachel's mouth as her lips were forced to press against his crotch. Her rubberized womb was likewise filled with cum.

"Mmmm, that actually tasted really good. Better than human male cum. It was salty, but had some sweetness to it too, hehehe…" Rachel giggled, still a bit dazed from her orgasm.

They slowly pulled out, shoving both Rachel and Gwen plus a few other girls into a cart. The group was pressed together, their mass shifting as they squished against each other. Parts of them compressed while others expanded.

The cart was wheeled away and into another room. One by one, they were yanked out of the cart and carried to a line of metal chairs. Two metal rods were on the seat of each chair and Rachel was brought to hers, she soon found them inserted into her holes, forced to sit down on them.

Curved metal clamps locked around her legs, holding them against the base of the chairs. Soon, her arms are bound as well. Gwen was forced into the seat right next to her.

"What have you done to us? I just wanted some fun in the sun!" Gwen moaned as she wiggled in her restraints.

Having a background in science and being really good with math, Rachel put it all together. "I know Gwen, and tell me if I am wrong, bugs. The doll transformation was for storage reasons and to survive the G-forces of the lift off, but also to make our bodies perfect for these extraction devices. As I am sure, even our nipples are rubber, which means more extraction by inserting tubes into our rubber nipples to milk us."

"Clever doll. You have gotten part of it. We have also improved the lifespan of the cattle, so you may be milked longer." The little gray man grabbed Rachel's breast and squeezed it. As he pressed against her skin, other parts inflated like a balloon.

The window girl was carried out, a re-inflated rubber doll herself. She was even more mindless than before, not doing a thing. She was placed on her rods and locked in place.

Soon, the Gromos picked up clear suction cups. Two of them pressed against Rachel's nipples, the small tubes entering the holes in the middle. The rods then started to pulse inside of Rachel's rubber holes.

"Haha, you might have turned my brain into goo and sucked it out, but I did have high grades, not in English, but still enough to... Ooohhhhh oh god, the tubes entering my nipples feel ooooh goood oooo, really really good like mini pussies."

Gwen moaned. "Make it stop! Ahhh! It feels too good!" She wiggled around in her bindings.

"Of the 345 units we have collected on this expedition, 20 have been selected to produce sustenance for the crew. The rest will remain in storage until our return and then sold."

"You can't do this, we are, ahhh, humans! We have rights!" An ebony doll cried out.

There were a few complaints and moans coming from the other dolls strapped to the chairs. Soon, dildos attached to tubes lowered from the ceiling. One by one, the space men grabbed them and shove them into the parted lips of their captives. After taking care of the first several, they got close to Rachel and Gwen.

Rachel looked down and so did Gwen, trying not to look at the other girls as the strange dildos were forced into their mouths. Now, what looked like a very thick cream flowed down the tubes from there nipples. "Okay, I have to admit, this is not so bad of an outcome here, hehe."

Gwen moaned, looking at Rachel like she was crazy.

"What? It could be worse, milked and fucked. Oohhhh, it's not so bad."

"Ahhhh! You are enjoying this!" Gwen closed her plastic eyes. "They’re going to treat us like property!"

One of the Gromos grabbed the dildo hanging in front of Rachel, and she could see the small hole at the end. He moved to put it into her mouth. Behind him, an Asian doll struggled to avoid her oral dildo.

Rachel open her mouth greedily as she saw it pulsate like a real dick. "Ahhhhhh!" She couldn't wait.

He shoved the rubber phallus into Rachel's open mouth, pressing against the tight walls and locking itself into place. Soon, a liquid moved down the tube and into the toy, exiting from the hole at the end.

Gwen just closed her eyes and took her own dildo, sucking on it slowly.

"Mmmmm." It was forced right down their throats, but it tasted really sweet, almost like sugar syrup.

The Gromos left the room once all the dolls had all of their holes stuffed. They were left to orgasm as their milk flowed out of their inflated breasts and down the tubes. One of the dolls even started thrusting up and down on her chair. It wasn't clear if she was trying to break free or stimulate herself, but she was moaning like crazy regardless.

One thing was for sure, they had better get used to this, for it seemed that it was all that was in store for them for the foreseeable future.
