Prologue

The USCGC Observance rolled slowly over the waves, it's crew on high alert. Most held binoculars to their eyes. Captain Marke led the search crews by water as helicopters continued to search far off by air.

"Captain, we got word from the mainland the survivor has woken up and been debriefed." Lieutenant Mondoss announced.

"Did they say anything that might be helpful?" Marke asked.

"Well, actually, no. Mainland believes it must be shock or delirium from blood loss, but the story didn't seem the least bit truthful."

"Oh? And why's that?"

"I think, Captain, you should read it for yourself."

Part 1: The Cube

It started when a deep sea salvage crew found an ancient statuette among tablet fragments while hauling up scrap. Immediately, the Medkor Archeological Institute dispatched a survey team to search the seafloor for more artifacts, bring up small ones, and mark off sections for a more thorough excavation. Aboard the survey vessel, the RSV Callahan, was a crew of 10 people. The crew was made up of the lead researcher Dr. Hannah fritz (32), Gideon Wimber (28), Zeke Carroll (29), Lauren Daily(54), and 3 assistants; Chandler (21), Yu-jin (19), Eddie (23). The cook was Saya (26), Jose (27) was the deck hand, and Edward Coranis (64) was the ships Captain. Gideon was the deep sea ROV pilot. At first it seemed like a isolated find. A smuggled artifact that fell overboard many years ago. Until they found the box.

Hannah was studying pictures of the first statuette that had been discovered. It was an interesting figure, not quite 6 cm tall. It depicted something that seemed overtly feminine with what was apparently large breasts, wide hips, and an oversized vagina. From its sides was a confusing mess of ends that the team couldn't quite figure out if it was meant to be part of the woman/creature, or if they represented wind around her of something like that. Prehaps it was a fertility goddess of some kind? She pondered the possibilities and how something around 100, 000 years old ended up so far off the Florida coast. Gideon interrupted her musings.

"Hannah, you won't believe it!" He said, carrying a sealed containment tank.

"What is it?" Hannah asked excitedly.

"Take a look."

It was some kind of box. It looked made of stone, but there was strange grooves in it that had been covered by sediment. It would need to be carefully cleaned to see more. But there was no doubt, it was a perfect 30 cm cube and couldn't possibly be naturally formed. Gideon returned to his ROV while Hannah started carefully cleaning the square, making sure it wouldn't damage under the new lack of unser sea pressure it hadn't experienced in centuries. It was hours later Gideon came to get Hannah. She was late for dinner in the mess hall.

"Hannah? Did you hear the call? It's time to eat." He said sticking his head in the door.

"Is it? I must have lost track of the time." Hannah said holding the cube up to the light above her desk.

"You took it out of its tank?" Gideon said walking over. "You're not supposed to do that... and you're not wearing gloves!"

"It's fine, Gideon. Don't be such a stickler for rules." Hannah said mesmerized, not taking her eyes off the cube for a second. "Here, take a look."

Gideon took the cube. It was surprisingly light for its size. Despite looking like a solid rock, it must have been hollow. Carvings decorated the outside, wrapping all around every side. The carvings were strange. They didn't really form any real picture but there was something sensual about them. Gideon could not put his finger on it, but it seemed so... sexual. He felt his dick growing in his pants with a flush of heat. It took a lot of mental strength but he forced himself to put it in a padded box. Hannah stared at him expectantly, discreetly grinding against the corner of her desk. Gideon slapped tape over the box, sealing the cube inside.

"There. It's ready for it's ride to mainland. Shall we eat?" Gideon asked, his hormones returning to normal. Hannah was a married woman, and he was not the one to let a woman play any man - especially her husband - for a fool.

"No." Hannah rubbed her head, her senses clearing. "No, I'm not hungry."

Part 2: The Tingle

Early the next morning, Gideon joined his assistant Yu-jin at his station. She was a pretty Korean girl with a small frame, small breasts, small butt, short hair, but had a bubbly personality. She was a bright and gifted student with a love for what she did. She also had a crush on Gideon. She watched over his shoulder as he maneuvered the ROV over the ocean floor.

"Anything yet, Dr. Wimber?" Yu-jin asked, directly in his ear.

"A few things. Odds and ends, here and there." Gideon answered. "Nothing that can't wait until the full excavation."

Yu-jin began to massage his shoulders.

"What is Dr. Fritz up to?" She asked.

"Hannah? I don't know exactly what she's doing right now. Why?"

"I heard some oddly suspicious noises as I passed her lab last night. Like, coming from inside her lab."

"I'll... be sure to ask her about it."

Yu-jin just giggled as they resumed their scan for a few more hours. Zeke Carroll was the secondary lead marine archeologist after Hannah. He was skinnier than Gideon, but not much shorter. His long curly blonde hair he kept tied up in a man bun. He was definitely more of a - sit at a table/desk staring at stuff people brought him - kind of person. Lauren Daily was a dark haired woman with a mom bod. She was divorced with two children in college. Gideon happened upon them with Hannah in her lab. Hannah, Zeke, and Lauren stood around a table.

"Hey! What are you doing with that?" Gideon demanded, entering the room.

Hannah held the cube out under a light while Lauren and Zeke watched it in amazement.

"I was just showing our team the greatest find of the century." Hannah said proudly.

"The greatest fi-? Put it back. You're contaminating the sample." Gideon said snatching it from Hannah's delicate hands.

"Dr. Wimber, " Zeke said, sounding exasperated, "we're the professionals on this. I don't tell you how to drive your little sub, do I?"

"Maybe you should sometime." Gideon retorted without thinking. The feel of the cube's curves in his hands sent a rush of excitement through him, his soft cock ran hot and began to harden. Gideon hid it by moving to stand behind the table.

"It's OK, Zeke. That's all I wanted to show you." Hannah said, licking her lips. She never called Zeke by his first name before, but she was feeling frisky right now.

Zeke and Lauren left the room, whispering about what the cube might possibly be. Hannah shut and locked the door behind them before returning to Gideons side.

"You need to relax more." She whispered seductively, taking the cube from him and setting it on the table.

"Put it in its box and leave it there." Gideon ordered while desperately trying to ignore the fact his dick was painfully straining against his pants.

Hannah forcefully grabbed his shoulders and pulled him away from the table, staring down at the tent in his pants.

"Hannah! Dr. Fritz, we-" Gideons protests were interrupted by Hannah squatting down and pulling his pants and boxers down in one motion.

His cock popped free. It was a solid 6 inches. Hannah literally purred in excitement and licked her lips before taking the tip in her mouth. Gideon could only rest his head back and moan as Hannah started to suck is cock with hungry enthusiasm. It didn't matter to him at this moment that she was married. He craved release and this willing young bombshell of a woman was more that willing. It was only natural... wasn't it? Hannah cupped his balls in her left hand as her right reached under her dress and began furiously rubbing her clit. Gideon looked down. He could see down her top, her glorious cleavage from her fat breasts in full view. He couldn't fight it and came in her mouth. Hannah sucked down every drop as she squeezed his balls to try and get more. The pain of her grip and post nut clarity hit him hard. He pushed Hannah off onto her back. Her short dress riding up to reveal she was not wearing panties and her pussy was moist and glistening.

"We can't do this... do that ever again!" Gideon affirmed more to himself than to Hannah as he fought to get his pants up. His legs were shaking.

Hannah giggled as he exited the room quickly, licking her juices off her fingers.

____________________________________________

Part 3: Body Heat

Try as he might, Gideon couldn't get back to work. His mind muddled by the thought of Hannah sucking his dick. "Why did I leave? Her pussy was so wet!" He thought to himself. "I should have just rammed my cock in her and fucked her till she was full of my cum!" He walked around his cabin aimlessly for a bit before punching the wall and sitting on his bed. "No, this isn't right." His thoughts continued. "I'm not some trash that gets sucked off by another man's wife. Why was I so... aroused. Was it the cube? It has to be! That feeling when I touched it... was almost like.... " A knock at the door interrupted him.

"You still alive in there?" Jose asked. "I heard a 'bang'."

"I'm fine. Just frustrated." Gideon answered. He heard Jose hustle away, worried Gideon would share why he was frustrated. Jose didn't care for hearing other people's frustrations. He had enough of his own.

Gideon left his room and walked around until he found Zeke. He was talking with Eddie in the rec room playing on the fuzball table.

"Dr. Wimber! Come join us." Eddie laughed. "This guy stinks."

Zeke hit the table after the ball slipped into his goal. He turned to face Gideon.

"Need something, Gid?" Zeke asked.

"I wanted to clarify my concerns this afternoon. I wasn't questioning your professionalism or authority." Gideon clarified.

"Think nothing about it, dude. It's all good."

They chatted a bit more before Gideon moved on back to his room. Passing Lauren's room he couldn't help hear a suspicious noise. He paused and listened. It was moaning with an occasional wet slap. From the sound of it she was pleasuring herself. He moved on passed the door. The bell for dinner rang out over the P.A. system. He looked back. A disheveled Lauren left her room, buttoning up her shirt.

"Hey, Lauren!" Gideon said catching up to her. "What did you think of Hannah's golden find?"

Lauren laughed. "It's weird, innit?" Her mature milf breasts looked bigger in her buttoned up top.

They sat together in the mess hall. She would constantly rub her boobs against his arm as they talked, to often to be accidental. Was she hitting on him? She was never interested him before. Gideon looked around. A table down Zeke sat next to Saya, whispering into her ears. She would give a flirty laugh every so often, although clearly Zeke was wanting more. That was odd as well.

"Penny for your thoughts?" Lauren whispered, her hot breath on his neck and her hand slid on his thigh.

"They seem to be enjoying themselves." He nodded to the other table, a heat rising in his groin.

"They're just kids to me." Lauren whispered. "No older than my kids. Let them have fun."

Gideon felt Lauren's hand slide from his thigh to his cock. She rang her fingers along his length through his pants.

"Shall we get back to work?" She said, standing up.

"Yes! Absolutely!" Gideon got up, slightly bent over to try and hide his erection. Lauren led him down the cabin halls to her room.

"I got a theory on that cube. Come by later and let's discuss it." Lauren seductively slid into her room, her wide mature hips swaying as did so.

Now alone, Gideon tucked his erection into his waistband and considered barging into Laurens room, tearing her clothes off and fucking her senseless. Clarity prevailed and he decided to check up on Hannah in her cursed lab again. She had missed dinner for a second time. Without knocking he slammed the door open. His eyes widened as his jaw dropped. Hannah was on the table on her knees, bare naked and rubbing her pussy against the corner of the cube. A puddle of her juices covered the table. She turned her head to him without stopping.

"Fuck me." She whispered, her eyes full of desire.

Gideon walked in and slammed the door behind him. He kicked off his shoes, shred off his clothes, and crawled up on the table. It was a strong metal table, but still groaned under the weight. The two kissed each other roughly. This wasn't about love. It was all lust. Gideon squeezed her tits in his hands, pinching her hard nipples. Her tits were soft and warm, perfect for grabbing. Gideon moved the cube aside, Hannah immediately knocking him onto his back so hard he nearly fell off the table. She straddled him, her pussy dripping in anticipation as she lined it up with his cock. She slammed down all at once. Both gasped at the sensation as his cock filled her up. He grabbed her hips roughly and aided her as she fiercely bounced up and down, taking his full length every time. Her married pussy squeezed around his cock in a death grip.

"Take this bitch! Take a real fucking cock!" Gideon growled.

"I'll take it!" Hannah yelled back, her nails scratched his chest so hard it bled. "I'll take all your fucking cock AND all your fucking cum!"

She slammed her hips down harder and harder, trying to get him deeper into her. Suddenly her hips contracted hard as she threw herself back, barely catching herself with her arms as she squirt all over Gideon. From his cock to his face he got drenched. It was so hot and smelled intoxicating he couldn't help cum. Holding onto her hips, he held her down and began unloading rope after rope of hot cum inside her. She panted and gasped loudly before collapsing on him. Her head resting on his chest. Both panted for a long time until they caught their breath. Gideons softened cock finally slipped out of her, a stream of cum following it out.

"That was amazing." Hannah whispered, kissing his chest. "Let's do it again."

Part 4: The Shape of Lust

Gideon staggered down the hall to his room. Chandler gave him a knowing glance, having heard him and Hannah's lavish lovemaking from earlier. Gideon avoided all eye contact as they passed. Gideon didn't feel shame. He was desperately trying not to get hard again. It was as if his sexual refractory period post orgasm was less then a minute now. Passing the showers he heard yelling and loud groaning. Peeking inside he saw through the steam that Zeke had Saya leaning against the shower wall shoving his cock in her asshole from behind. Saya looked back and locked eyes with Gideon. Instead of stopping, she started throwing it back harder and faster. Gideon walked away as he heard the Zeke yell out that he was coming. He knocked on Lauren's door. It was late now. He wasn't sure she was awake.

"Come in!" She called out from inside.

Gideon opened the door and without hesitation entered. Lauren was lying on her bed naked. Slowly stroking her hairy milf pussy. Gideon stripped and crawled up next to her, sucking her slightly sagging breasts. Lauren stroked his rock hard cock slowly, using the same hand that was wet from playing with herself.

"That cube..., " Gideon asked between sucking on her nips, "... what the hell is it?"

"Something extraordinary." She replied, kissing his lips and wrapping her legs around his waist. "It's like a way to a different world."

Gideon slid his cock inside her. 54 years and 2 children did nothing to loosen her pussy. It was still hot, wet, and tight. Gideon started pounding away hard, making her aged breasts bounce around on her chest.

"Fuck it's been so long!" She whimpered. "Stay with me! We can fuck till morning!"

Gideon grunted in agreement as he thrusted away at her hips, his balls slapping against her ass. They continued this way, fucking and coming, until the sun rose.

"How can the cube do this?" Gideon asked as Lauren was cleaning his cum off his cock with her mouth.

"It's inside the box. It can open." She said in between. "It lives inside. It's wet. It's horny. We touched it. Now it calls to us... through us to the others. Soon we'll all be a part of it."

Creeped out, Gideon managed to pry his rock hard cock away long enough to escape. Lauren wandered out into the hall naked behind him. Gideon made his way to the bridge. "If the box really was doing all of this, " he thought, "then we need to open it! No! We get rid of it? Yes! Get rid of it then we can fuck everyone on the mainland! Wait... that isn't right... we need to... fuck. Cum. Get fucking HELP!"

"Captain Coranis." Gideon announced as he entered the bridge. "We need to make for mainland immediately."

Captain Coranis sat behind his big steering controls. He eyed Gideons waist. His bulge was still visible.

"You seem to be enjoying yourself well enough. But yes, we must return soon." The Captain laughed.

"I'm serious! Something is happening to us!" Gideon said, covering his crotch with his hands.

"Indeed there is. And you know what?" The captain stood up. He was bare from the waist down his old cock dripping cum. "I don't mind it one damn bit."

____________________________________________

Part 5: Ruin

The Captain stood unemotional, not the least bit insecure about his nudity. Hannah rose up from the front of his chair, barely clothed with cum on her chin. She hugged the cube - or rather the box - against her chest tightly.

"Come on, Gideon." She moaned, her eyes glazed over in lust. "Don't be a prude. We're all alive! This is what everyone dreams of! Especially every man."

"I'm not not 'Every man'!" Gideon retorted, fighting not to cum right then and there. "I'm getting you help!"

Gideon ran downstairs. He saw Lauren naked and furiously sucking Chandler and Eddie's cocks. "Just like my boys!" She moaned. "So young and handsome!" Gideon ran on deck looking desperately for Jose and Yu-jin, who were seemingly the only one's unaffected. Jose was yelling at Zeke and Saya who were fucking ruthlessly on the deck.

"Jose!" Gideon yelled. "We need to go! Have you seen Yu-jin?"

"Like hell we do!" Jose shot back, grabbing a mop. "Stop it you fucking dogs!"

Jose hit Zeke with the mop. He just laughed. Saya broke free from under Zeke and lunged at Jose, grabbing his leg and tripping him. Zeke and Saya began stripping his clothes off. Gideon kicked Zeke in the side and sent him rolling. He grabbed Saya and pulled her off but she turned on him, grabbing his balls like a vice. Jose ran off, leaving Gideon at their mercy. Zeke and Saya stripped Gideon naked in seconds. Saya took his cock in her mouth and started sucking furiously. Zeke lined his dick up between Gideon's ass cheeks and started humping. Suddenly, a blast of freezing water blasted the three of them. Yu-jin was standing behind a hose and continued to spray Zeke and Saya until they backed off. Gideon staggered to his feet and ran towards her.

"Come on!" Gideon shouted as he ran passed, grabbing her hand. "We need to get to the life rafts!"

"What the fuck is going on!" Yu-jin shouted as she ran, unable to take her eyes of Gideons nude body. In particular, his swollen hard cock caught her attention.

"It's this cube, sweetheart." Hannah said as she and the captain blocked their path. "It's lust personified."

Gideon and Yu-jin turned to run another way, but their path was blocked by Lauren, Chandler, and Eddie who had subdued Jose. Behind them charged Zeke and Saya. Gideon braced for a fight. Hannah stepped forward, holding out the box.

"Stand aside, Gideon." She demanded. "Let Yu-jin feel the box. Let her feel the lust, and then she can decide whether to leave or not. But first..."

Hannah walked over to Jose who was still pinned by Chandler and Eddie. She held the box to his exposed cock.

"You will all join us soon. This will just speed things up." Hannah moaned.

Jose's cock instantly swelled at the box's touch. He let out a loud groan of pleasure. Unable to handle it, Gideon lunged at Hannah. The captain intercepted him and sent him to the ground with a single punch.

____________________________________________

Part 6: The Last Temptation

A sharp pain from the back of his head slowly made Gideon come to. His vision was blurred and out of focus. As it cleared he found himself in the mess hall before the crew. They were all naked. He looked around for Yu-jin but she wasn't there. He prayed she had managed to get away. On the floor before him was the damned box. He tried to reach for it, but realized his hands were tied behind his back to a table leg. He tried to break free but the rope was too strong and the table was bolted down. Hannah picked up the box and brought it to him. He could see fresh cum running down her thighs as she approached, instinctively making his dick hard.

"It's time." She declared. "You're the last one."

"Stop this." Gideon said, although his voice betrayed the urge to give in. "We can stop this! Get back to normal! You just need to -"

"But we don't want to stop this." Yu-jin stepped forward from behind the crew, her naked little petite body trembling slightly with excitement. "Dr. Wimber... Gideon... all my life... I have never felt so happy! So free! Please, I've had a crush on you for so long. Fuck me. Fuck my tight pussy and fill me with your cum! It's what I've always wanted since I first saw you!"

Yu-jin rubbed her unshaven pussy as she spoke. She stroked her small a-cup boobs with the other hand. Gideon's cock dripped precum as he felt his mind become hazy again with the urge to breed this woman. To use her body for his gratification. That's what this was all about after all. Sexual gratification. He felt the rope go loose as Jose untied him. Gideon finally excepted he was the last one with a chance of ending this. He could grab the box and toss it overboard, or maybe in the oven? He looked at the cube - that damn box - for a moment, but in the end he held out his arms. Yu-jin ran across the room with a squeal, leaping into his strong arms. He held her small frame off the floor as she grabbed his head and started kissing him passionately. The room seemed to spin around him.

Gideon took Yu-jin's legs over his shoulders as he grabbed her ass, holding her over the box as he lowered her down onto his penis. It was a tight fit. He could barely fit his length into her. As her hymen tore and blood dripped from her deflowered snatch, she just groaned in ecstacy from the sharp pain and the fact her crush had finally made her his. Gideon started lifting her up then dropping her down onto his shaft. He was vaguely aware that around them an orgy was forming. Saya sucked the captains cock as she rode Chandler cowgirl style while Eddie used her ass. Zeke had Lauren face down sucking Jose's dick as he railed her from behind. Hannah for her part, pushed the box under Gideon and Yu-jin before licking Gideon's balls as he continued fucking Yu-jin. Yu-jin held on tight to her partners chest as she orgasmed, spraying all over Hannah's face. Once he realized she was coming, Gideon blew the biggest load of his life into her. Her womb filled with his seed as both cried out in pleasure. Finally, Hannah's saliva, Yu-jin's squirt and virginal blood, and Gideon's cum dripped down onto the box. The box absorbed it all and slowly started to vibrate.

____________________________________________

Part 7: Callahan Down

The box shook so fiercely it interrupted the orgy that was in progress around it. Gideon moved away with Yu-jin in his arms, his dick still hard and buried inside her. All eyes watched as cracks appeared on the top of the box and folded outwards. Inside was a fleshy pink lump of meat. From the meat, what looked like a flower bud rose and opened. Each petal looked like the long lips of a vulva. They grew and enveloped the box. Then they grew across the floor, wet and glistening. The smell threw all the crew besides Gideon and Yu-jin into a fit as they crawled onto it and began licking, sucking, rolling, and humping the quickly growing mass of flesh. Gideon stepped onto it to avoid getting crushed as the flesh reached the walls and went up to the ceiling. It extended out the doors and into the hallways. The ship began to creak from the pressure and rapidly growing weight.

Yu-jin slid off of Gideon's dick and walked towards the center of the mass where the box once was. A hole began to appear. The hole began to expand rapidly and it became clear what it was. It was not just a hole, it was a full on vagina.

"The box is..." Gideon couldn't believe it, "a doorway... to what?"

"Gratification." A voice declared from the depths of the massive snatch.

A creature crawled from the hole. It resembled a man, but its penis fluidly morphed into all sorts of different shapes and sizes. It even could become the cocks of different species. Following it was a feminine creature. This one resembled a busty woman, her belly swollen from pregnancy, her asshole and vagina twitching and prolapsed. They were followed by two more, the first was an amalgamation of pussy, tits, and lips, and the second a man with a penis for a face, the foreskin acting like a hood, and the body like a squid with each tentacle being a massively elongated penis.

"Nythra'vax thanks you for finding her box and in offers you her gift. Enter her vagina, pass the doors of her cervix, and feel her warm embrace and lust both now and forever." The first masculine one offered.

Like people possessed, the crew marched towards the four creatures and began engaging with them sexual. Yu-jin grabbed Gideon's hand and pulled him forward towards the creatures. "This is it." Gideon thought. "The first day in the rest of our lives." A sharp crack from the hull as windows shattered with the warping walls brought him back. The flesh - this ever growing vaginal portal - was going to sink the ship! He pulled free from Yu-jin's hand.

"Cum now, Gideon Wimber, " the female creature said as Zeke and Lauren sucked her swollen lactating breasts, "do not fear us of Nythra'vax. She is the mother of pleasure, and in her womb awaits sexual gratification the likes of which you can NEVER find anywhere else. She is the pleasure of intercourse personified."

The mass off breasts, vulvas, and lips moaned in agreement as Chandler and the captain competed to cum in as many of its holes as possible.

"No way! I don't know why I can resist you, but it must be for a reason!" Gideon said, his cock pulling him towards the massive vagina that was now enveloping the room.

"It means nothing." Said the first man as Yu-jin sucked his ever changing dick. "Your urges call to us. Your sexual organs belong to Nythra'vax now."

"THEN HAVE THEM!" Gideon shouted.

With all the willpower he possessed, Gideon grabbed a kitchen knife and sliced off his penis and testicles in a single swipe. He tossed them into the pit and limped out of the room, the sound of sex and ecstacy ringing in his ears. As he staggered to the back deck and tossed a life raft overboard he noticed the ship was very low in the water. Nythra'vax's vaginal lips had grown to reach the deck and the weight was pulling the ship under. Gideon hopped in his raft and started rowing away. He watched as the ship finally sunk.

"She is coming, " a disembodied voice whispered in his ears, "and she is horny."

From loss of blood and shock, Gideon passed out.

Epilogue

Captain Marke chewed his gum thoughtfully.

"That's a hell of a story." He said at last.

"It's bullshit, right?" Mondoss asked.

"This planet, these seas, all sorts of things can happen. But pussy portals and litteral sex fiends? Hell nah."

A voice cackled over the radio.

"Headquarters to all units. It's been 72 hours and we are calling off the search. I repeat: all units we are calling off the search. Over and out."

Marke and Mondoss shared a knowing glance as they turned the ship around and started back towards port. The ship sailed off to the distance as blood and semen slowly floated to the surface behind them.
