Her contact had given her the coordinates to a very large cave system in northern Spain. He told of an ancient idol that had found its way down there somehow. If legends were to be believed, sometime in the 1700s, during the War of Spanish Succession, a group of locals found a path into the deeper areas of the caves and decided to live there. They would venture up and trade with the town they had left, but they became more reclusive as time passed. Eventually their town was captured, but rather than fight back, they decided to sever outside connection and blast a section of the cave entrance, sealing themselves in. They still had small paths out, but most of them stayed, ignoring the outside world.
Just before all of that transpired, they supposedly bartered for a relic from early man – a statuette of some form of earth mother. Sonya originally discounted such a wild tale, however, after some research, it might be plausible and not many outsiders knew about the reclusive migrants. Their group travelled along many winding backroad to come upon a ten-foot wide sinkhole, deeper than they could estimate. Their driver took his fee and left the trio to explore alone.
Sonya, Brooke, and their contact, Arturo checked their gear. The two girls were both friends from college. As adventure junkies, they started exploring caves in various states during the last two summers, but this year they wanted to up the ante. Both kept in amazing shape and were very active. Brooke was tall, slim, and had lusciously full lips. Her smile was her best feature and her big brown eyes added to her seductive looks. Brooke stole glances as they rifled through their packs. Her rich, golden-brown skin radiated warmth as she stretched her neck.
On the other hand, Sonya was a polar opposite as looks went. She was just as limber and muscular, but she was short and pale. Her grayish green eyes gave her a cold appearance, but her dimpled cheeks and reddish brown hair helped to offset it. She wasn’t sure why Brooke loved her, but she didn’t question her good luck. Sonya wound her long hair into a ponytail after confirming that all of her items were prepared.
Arturo waited by the edge of the entrance, peering into the blackness. He was an older, quiet man, who seemed to tolerate the chatty girls, understanding that they wouldn’t screw him over like other, more experienced explorers might. They all understood that this was a casual cave exploration, but there was always that hope that they would find something more. There was always the slim chance that the stories were actually true.
They began their climb down the sheer rock face. Arturo explained the path they would find, as he had started to explore on his own before they arrived. They only went about thirty feet down before Sonya saw the first ledge he had mentioned, with a crawlspace leading deeper into the cave system. They continued into the damp, dark caves, crawling in tight spaces and weaving up and down through claustrophobic caverns. Soon they passed the point where Arturo had ventured. Nearly an hour had passed and they continued farther into the unknown. “I think I see light!” Brooke called from the center of their line.
“We shouldn’t be near the surface yet.” Sonya pivoted and walked along the ledge, back to her partner. They flicked off their headlamps, definitely seeing a faint light above them. The opening was out of reach, so Arturo helped to boost them one at a time. Sonya led again, crawling into the small alcove and finding some loose stone at the end. She used her gloved hand to push it through, allowing the ambient light to flood their passage. They crawled out and found themselves in an unnaturally wide hallway.
Brooke crawled through, gasping as her eyes adjusted to the light source. “It’s a torch!”
“Yep, good job captain obvious!” Sonya whispered as she helped her friend to her feet. Arturo barely fit, but he seemed more nervous than awe-struck. He directed them down the stone hall and they walked cautiously, passing a few more crackling torches before they came to a small room. The two girls shook with excitement as they gazed upon a small, roughly carved figure resting upon a stone pedestal. “Is… Is that really it?” Sonya asked with wonder.
The guide nodded, motioning for her to take it. Sonya hesitated before finally reaching out to lift the heavy limestone figure. It had no head or arms, and the legs stopped at the knees. The design was clearly of a pregnant woman’s midsection, showing her prominent female curves. She offered it to Brooke, who took it gently. “It’s amazing.”
Sonya looked back towards the hall. “What do you think is down the hall?”
Brooke paused to look as well. “Do we really want to find out?”
“Do you think people still live down here after all this time?”
She inspected the heavy stone idol. “I mean, there can’t be, right? It’s been hundreds of years.”
“Maybe there is an entrance somewhere we don’t know about. Maybe they’re looking for this thing too.” Sonya took the statuette back. “This could be worth millions.”
“Forget that! Imagine how famous we’ll be.”
“Let’s just go back the way we came and whoever is down here won’t even know we were here.”
After inspecting it top to bottom, Sonya wrapped it and placed it in her pack. They went back to the crawlspace detaching their lifelines temporarily so Arturo could go ahead, checking for any loose sections of the ledge at the exit. Brooke went in the middle again, finding it much harder to squeeze through this time. Sonya got on her stomach and nudged her shoulders through the cracked edge of the hall, but she was too big to go farther. “I can’t seem to get my boobs to fit!” She could not turn on her side, either, as the section had limited height.
“Just squish through!” Brooke called, unable to look back to her friend.
Sonya struggled, but eventually conceded. “I can’t, I just don’t fit this way.” She shuffled back, raising up onto her knees and looking down to inspect her chest. She felt her breasts beneath her mud soaked coveralls as Brooke also backed out of the crawlspace.
Brooke gave a dramatically confused glare. “Havin’ fun back here?”
“They feel weird.” Sonya slipped her pack onto the ground and unbuttoned the front of her outer layer. She peeled the coveralls away to reveal astounding cleavage. Her modest sized breasts had grown visibly larger, pushing her grey tank top outward. Both girls stared for a long time.
“Are you fuckin’ with me, Sonya?”
She quickly shook her head. “No! I don’t know!”
“How the hell did your boobs get so big? They weren’t that huge when you were getting dressed this morning!”
Sonya shrugged, causing her chest to raise slightly, casing a little more skin to peek out. “They feel kind of weird too, kind of warm.”
Brooke remembered their guide, as she turned and knelt, calling with urgency through the opening. “Arturo! We’re stuck!” There was no response. They called a couple more times, but they finally decided he had gone ahead without them. “You don’t think he’s going to fuck us over, do you?”
“Oh shit, maybe. We still have it, though.”
“Fuck! He might bring a crew back and kill us to get that thing!”
“We have to find another way out! Maybe we can team up with whoever put that torch up.” The big-chested girl put her backpack on again.
The path led upwards, getting surprisingly warmer as they ascended the gentle slope. They noticed a few more side exits, but all were too small for Sonya in her larger state. Both girls took the tops of their coveralls off, tying them around their waist. Sonya lamented, as her once reasonable breasts had ballooned outward and downward, jiggling with each step. It started throwing off her balance, as they wobbled heavily, swaying side to side with even the slightest motion. As they climbed she tried to cover them with her coveralls, just to keep them in check, but it came nowhere near close to buttoning again. She retied it around her hips as Brooke watched.
“You know, I think my chest grew too.” Brooke fondled herself. “Nothing like you, but they definitely got bigger.”
Sonya paused as she noticed her belly had expanded as well. “What the fuck?” She slipped the heavy coveralls lower and her tank top upward. Her stomach puffed outward, looking like the first few months of pregnancy. Sonya burst into tears. “What is happening to me?!”
Brooke embraced her friend, pressing her pleasantly heavy breasts between them, stroking her hair to relax the sobbing girl. “I don’t know, maybe… maybe it’s something in the air… Maybe you are allergic to something. We’ll figure it out once we get out of here.” Brooke looked into her eyes with compassion. “We have to keep moving or we might not make it out of here.”
Sonya agreed, wiping away her tears. “I can make it.”
They only went about twenty feet down the hall before there was an abrupt turn leading to an out of place wooden doorway. Brooke’s mouth hung as she looked back and forth between the door and her expanded friend. “Do you think this…”
Sonya was more skeptical, but unable to directly deny the thought. She gathered courage before pushing the rickety door open. They stood in silent wonder as they looked down upon a large group of houses built in a large cavern. Torches were scattered between the homes, giving patchy light to the people who moved between their homes.
“They are still living here!” Brooke’s voice danced with amazement. “They still fucking live here!”
They heard a man shout from below as he pointed and bounded up the stone ramp. Others followed as they ran up the ledge. “Shit, what do we do?!” Sonya looked for an escape. “Back in here!” They closed the crude door, knowing it was a temporary blockade. “They’re going to see that we took it!”
“Uh, let’s just say that Arturo grabbed it and ran!”
“What if they search our stuff?”
Brooke reached into her friend’s pack and unwrapped the figurine. She slid it down her pants and nestled it close to her privates. “No one will check there.”
“I don’t know. We should just put it back!”
Wood splintered as the door flew open. An angry man cursed them in Spanish as a stomped forward. He took their packs and tossed them to his followers. They rifled through the items, tossing them aside as they searched. The man in front wore a dirty t-shirt and jeans, with a machete hanging from his hip. He regarded them with a cold stare. “Who are you?” He asked in English.
Both girls knew some Spanish, but Brooke was better versed, so she responded in his native tongue. “We are just cave explorers, we just stumbled down here. We won’t say a thing, we promise!”
“Dumb Americans.” He sized them up with his eyes. “Strip.” The nervous girls looked to one another. “Now!”
Sonya took off her helmet, unlaced her hiking boots, and slid her coveralls onto the floor. The tank top was stretched upon her fleshy chest with her nipples showing through. Her belly was visible beneath the raised shirt, giving her a very pregnant appearance. Her butt had widened as well, making it difficult to slip out of her muddy garb. Her skin felt tight and warm, inside and out.
She did a double take as she noticed Brooke had expanded similarly. Her breasts had grown a few cup sizes, but her notable gain was in her squishy rump and puffed out belly. Her once firm backside had doubled, expanding her hips and upper thighs to match. With a more pronounced pear shape from behind, her growth caused a great deal of trouble as she tried to take the lower section of clothes off. She grunted as she fought to slip her snug coveralls over her widened hips.
The man laughed as he drew a pocketknife and grabbed a small section of her clothes, cutting them just enough for her to slip them off. Sonya could see her bigger ass still looked young and tight, in spite of its size. Sonya stared for a moment at her friend’s noticeably larger stomach. She gasped, as she finally understood what she was seeing – Brooke’s belly was getting bigger as she watched.
“You two found your way into our relic chamber. We doubt it was by chance.” The man directed another man behind him down the hall. “We will check on our item while you wait.”
“Our guide, Arturo took it!” Brooke exclaimed, shaking with fright, seemingly unaware that her midsection was expanding. “He is heading out of the cave as we speak!”
The man shared another laugh with his companions. “He took it and you don’t have anything to do with it?” Brooke agreed hurriedly. “Well, I guess we should apologize then!” He reached forward, putting his palm upon her crotch. “But, what are you hiding down here?” He maneuvered the object and Brooke’s expression showed discomfort and surprise as he pushed the small figure into her pussy. “Guess it’s nothing. I don’t feel it anymore.”
Brooke’s belly continued growing as the man stepped back and spoke. “You don’t notice that you’re both puffing up like a fucking balloon? See, you dumb Americans try to steal the idol we found, but you’re too stupid to see that it’s a fucking trap!”
Brooke looked nine month’s pregnant at this point, and her breasts had grown as well. Giving her complete female curves that made her look awkwardly large, but still very desirable. The man walked over and reached beneath the girl’s enormous belly, moving her panties aside. He felt around for a moment before sliding out the stone idol. Brooke whimpered, lifting her hips as he pulled. He held the glistening object for everyone to see.
“This thing turns women into the fat cows they’re meant to be.” He looked into Sonya’s eyes. “Your turn.” He offered the wet statuette. “Put this in you.”
The man rolled his eyes as he put his knife away and drew his machete, pointing it at Brooke’s distended belly. “Now!”
Tears welled in her eyes as Sonya took the slippery idol and pushed it past her underwear, into her unprepared pussy. It made a squishing sound as she worked it inside, using her friend’s juices for lubrication. She moved her panties to hold it in place. The man nodded with a smile as he used his off hand to slap her crotch, forcing it in entirely. Sonya grabbed her privates and fell to her knees, grunting in agony.
“It wasn’t in all the way.” He sheathed his weapon, directing the other three men to help her stand again. They marched them to the doorway. As they passed their backpacks, Sonya could see the end of a red tube. She knew the danger, but she decided to try anyway.
She lunged, grabbing the flare as she fell onto her bloated belly and rolled against the wall. She twisted the cap and blinded everyone with the shimmering flame. She pushed it into the closest man’s stomach as he tried to grab her. She used all of her strength to jump up, stumbling for a moment before unintentionally tackling the other two men who stepped in front of Brooke.
The dominant man finally stepped in, his machete high as he was about to swing. A sizzling white flame pressed into his arm, causing the blade to tumble behind him. Brooke followed-up by using her added weight to plow the man backwards, knocking him over the edge of the stone ramp. He grabbed a jutting section of rock at the last moment, struggling to hoist himself back up the sheer stone’s edge.
The two girls got to their feet and trotted heavily down the ramp, glancing back at the recovering men. Sonya left the object in place, knowing that any pause might get them caught. They made it to the first few houses before they could see the angry group of men ambling down the pathway.
They could see a woman scrubbing the floor in one of the door-less homes. “Help us, please!” Brooke begged in Spanish. “They’re trying to hurt us!”
The older woman scrambled to her feet, shocked by the intruders. “Help, they’re here! They’re here!” She screamed.
Sonya grabbed Brooke’s hand, leading her outside and between two of the roughly made structures. They wound their way through the torch lit town, finding a window into an uninhabited home. Brooke went first; her tight, full-figure still had enough strength to jump through the opening. She grunted as she landed upon the stone floor. Grumbling as she crawled aside. “Hurry!”
Sonya grew huge since the object was inserted. She could see her arms were notably larger, leading to her wider shoulders. Her legs were also massive now, leading to her huge rump, which had tripled in size, growing wider and expanding backward, but still remaining pliable and soft to the touch. Her breasts hung low on either side of her stomach, looking as big as basketballs and were surprisingly springy, bouncing out whenever they bumped her belly.
She tried to roll herself over the brick window frame, barely able to get her massive stomach through. She tumbled forward, but was stopped abruptly by her widened hips, which couldn’t fit through the opening. The motion caused the object she retained to slip halfway out and she could feel her juices trailing down her thighs. She struggled, but was unable to work herself free, hanging over the sill, her feet just above the cave floor.
“Just go, Brooke! They’re coming!” She could hear footsteps approaching from outside the home.
“There has to be a way…”
“Just go and send help. If they get us both then we’re screwed!”
The inflated woman nodded, leaving her lover to the approaching townsfolk. Sonya nearly cried as she watched the girl with the now hefty frame stumble through the doorway and bound clumsily around a corner. Within moments, she could hear men laughing behind her.
“You got a nice ass, chica.” The man spoke English as he grabbed two handfuls of her ass cheeks. Multiple hands groped her as she waited in place, unable to resist. She felt the hands spread her apart and slip the cold object out before a sudden warmth filled her loins. “Pinche puta, you’re gonna get used to this real fast.”
His cock felt small due to her added bulk. The man pumped her quickly, causing her full belly to rub upon the stone. She grumbled as another man stepped through the doorway ahead.
The leader smirked, watching her as she was fucked through the opening in the small house. He stepped forward and knelt, pinching her nipples, violently shaking her gargantuan, hanging breasts. “You’re a fucking cow now.” The man spoke in his native tongue. He worked her nipples, and to her amazement, she saw a stream of white liquid squirt onto the ground. The man used both hands to grab her right tit and put it in his mouth, drinking her breast milk as the man behind her continued, increasing his pace. Mere moments passed before he shot his warm fluid into her pussy. He filled her and stepped back, calling from beyond the blocked window frame. “All done!”
The man in front took another gulp before he let her boob swing back into place. He pushed her up and the men behind pulled, unsticking the bulky woman. They paraded her slowly to the center of the town, leading her inside the largest building she saw. To her horror, she saw Brooke sitting upon a stone bench next to two older, similarly inflated women. “I’m sorry Sonya.” They were both teary eyed as the men directed Sonya to sit alongside her friend.
“What are you going to do to us?” Sweat caused Sonya’s reddish hair to stick to her freckled neck.
“You used the artifact, so you’re going to provide for us now.”
“I don’t understand; how can we help you like this?” Brooke chimed in.
Arturo, their former partner, stepped in before the man could respond, smiling as he bowed his head. “You will provide nourishment and other services.”
“What?” She asked, dumfounded.
“You can give us enough milk to feed half the town. We didn’t expect to have both couples make it, but we aren’t complaining.”
“Our families will be looking for us! They know where we are!” Sonya exclaimed.
“No one will find you. You are two dumb American girls who went cave exploring in a foreign country. They’ll search the area for a time, but they’ll give up and assume you died. We’ve done this for a long time. Tourists are easy to deal with as long as you show a little patience.”
“What do you mean ‘other services?’” Brooke questioned.
“You’ll give us children for many years.”
“Why? You have plenty of women down here, why use us?”
“Those are our wives. We use you for kids to send topside. You’d be surprised how many people will pay for foreign children.” The leader slipped the idol from his pocket. “This little thing has been great for us. It only effects women and outsiders are always drawn here once we give them a lead.” He patted Arturo on the shoulder. “So, my friend, which do you prefer?”
Arturo stroked his chin as he thought. “This one seems more defiant, I like that.” He gestured to Sonya.
“Very well, you can do the honor.”
Sonya’s heart skipped a beat as Arturo took the artifact from the leader and spit on the rounded end. “You fight me and I will make your friend here regret it.” Brooke shuddered as he glared at her. He rubbed the moist tip on Sonya’s hidden lower opening, pressing it in and working it deeper. Soon it was in entirely, but the man kept pushing. He slipped his knuckles inside and then his wrist. The rounded object slid deeper, ushered by the man’s hand. He made it nearly to his elbow when he stopped and pulled his arm out with a wet slurping sound.
“You really gobbled it up down there! I see you’re becoming more accommodating. We will have to keep something in there to keep you pleased, won’t we?” He rubbed his hands upon her massive, curvy body. “You’re going to look nice in a few hours. You won’t be able to move ever again, but we’ll take good care of you.” The man laughed.
Brooke had fallen asleep somehow, unexplainably tired from the days ordeals. She turned and craned her neck. Sonya had gone from a slim, muscular woman into a heaping mess. She was enormous; all aspects of her body had grown. She sat a few feet taller, her pudgy arms crossed over her mountainous tits. Brooke noticed her belly was nearly as big as she was now. Sonya’s hips had spread outward and backward, pressing against her side and against the stone wall behind them. Her thick legs were stuck straight out, locked in place by her stomach.
“Oh my god!” Brooke couldn’t think of what to say.
“It’s okay,” Sonya’s puffed cheeks caused her words to slur. “He took it out a while ago.” He said I’m not going to get any bigger.”
Brooke was in tears, concerned for her friend. “Doesn’t it hurt?”
“No, no, it feels so nice now. He put a few things in me and it feels sooo nice.”
“What are you talking about?!”
“My body feels great when I orgasm now. You should try it. I mean, it’s better when you get bigger, but I think you’ll still like it.”
“She’s gone.” The other inflated woman said distantly. “He said that she’s going to get addicted to the feeling faster since she’s bigger.” She sighed. “We all will, I guess.”
The nameless woman’s partner burst into tears. “We’re all going to die down here!”
There was a long silence from the other two. Brooke finally turned to her friend. “What did he put in you?”
“Rocks. They feel great when I move!” Her eyes lit up as she looked down. “He said he has to take them out when he comes back, but I’m enjoying every second of it now!” Her enormous body shifted. A smooth stone clacked as it slid from between her legs. “Ooooh!” She quivered with delight.
