Author's Notes: I was hesitant to pull the trigger on this story because it originally took place in a high school setting and the characters were 16 years old and that came with "implications". I didn't write this as a cub/UA story or anything like that, I initially wrote the characters that age because the actual subject of this story is genuinely a personal fantasy I had when I was literally that age. The whole plot line, that entire thing was like one long daydream that used to titillate me when I was barely old enough to drive. I watched a lot of weird horror films and other movies meant for adults at an age when I probably shouldn't have and I guess it fucked me up because most high school juniors probably don't think about these kinds of things. So... the characters were just 16 because that's how old I was. It's a stupid justification, I am aware of that. I apologize for the misstep and I hope you don't get the wrong idea about me. Here's Frank Reynolds singing the "do not diddle kids" song from Always Sunny.

People did like the story however, so I retooled the entire thing into this revised version (no, I won't send you the original, don't ask me for it). The main idea and kinks in the story are unchanged but the characters are now kosher and the setting was changed to a university because being a junior in high school at age 18 suggests you're probably an underachiever.

"So, do you really think it's true?" Rilova said. She was speaking to her friend, Ghil, sitting across from her. The two young dinosaurs were in their university's library killing time until each of their next classes began. Usually they'd be doing class work or studying for a surprise quiz, though the two were fairly exceptional students and by virtue of actually showing up to lecture every day had the quiz material down. Their time in the library was instead usually spent using the university's state-of-the-art network to surf the web and dig up every last piece of information on the latest video games soon to hit shelves.

"Huh? What?" Ghil said, looking up from his graphing calculator.

"What the computer lab guy said, that almost a hundred years ago people from the science department of this school worked with the government." Rilova replied.

"You mean the guy who wouldn't shut up about aliens?"

Rilova rolled her eyes. "Well when you put it that way you're just dismissing the whole thing."

Ghil didn't say anything and his gaze slowly traced back down to his calculator.

"Are you playing games on that thing again?" She asked.

"Of course," Ghil said with a laugh. "The instructors usually frown on bringing video games to class but no one around here will think anything of someone using a calculator. For all they know I'm being studious and getting work done. They don't know I'm actually playing Mahjongg."

"I bet they did." Rilova continued.

"Did what?" Ghil asked, not looking up from his game.

"Work with the government. This is one of the most prestigious schools in the country, it's been around a long time. The people who teach science here all have doctorates, sometimes more than one, and the labs have equipment that doesn't look like it's cheap."

"What are you trying to say?" Ghil said, still not breaking eye contact with his game.

"I'm saying I bet if we snoop around we might find some cool stuff from back then."

"Like?" Ghil asked.

"I don't know," Rilova said leaning back in her chair. "Maybe we can find old files that talk about what the staff here did with the government?"

Ghil finally put his calculator down. "You're really caught up on this, aren't you?"

"It's just cool to me. Like a mystery or something."

"How do you propose we go around 'snooping' as you put it?"

"Ghil, we have an entire chunk of time to ourselves where we do nothing but draw pictures and play games on the internet. Nobody around here is paying any attention to us. We can probably go anywhere we want to and if we get caught we can just play dumb."

Their conversation was interrupted by the sound of Ghil's wristwatch beeping signaling that it was time for the two students to split up and go to class.

"Think about it, okay?" Rilova asked as she and Ghil started packing up their things.

The two students exited the library and before parting ways to each go to their last class of the day Rilova gave Ghil a quick hug.

The school day eventually ended and Ghil drove back home. He spent the rest of his day alternating between watching TV and grinding out levels on his computer in the latest RPG that had caught his attention. As the clock rounded out 9 PM he heard his phone chime from his nightstand. It was a text from Rilova.

"meet outside sci room tmrw instead of lib ;-)"

Ghil rolled his eyes and texted her back a single "k".

The next day on campus Ghil obliged and stood around outside the chemistry hall as his midday break rolled around. Students were walking around throughout the halls on their way to their various next orders of business and through the crowd he spotted Rilova heading his direction.

"I knew you'd come here," she said with a grin. "You're just as curious as I am!"

"Actually I'm here because we always hang out every day and it would be weird if for one day we didn't," Ghil sneered.

"Whatever. Come on, let's go in," Rilova said as she motioned toward the door to the biology classroom.

"We're just going to walk right in and demand to look through the back room?" Ghil asked sarcastically.

"No you idiot, around this time of day there aren't any classes running in this wing. Only early in the morning and late afternoon. There's nobody in here. Look."

Rilova opened the door to the classroom and sure enough there was nobody inside. She helped herself in and waved for Ghil to follow suit. Ghil let out a defeated sigh as he turned and entered the science room behind her.

"There," Rilova said pointing to the door in the back corner of the room behind the instructor's desk.

The two approached the door with Rilova leading the way. She reached for the handle on the door and attempted to open it, but the door was locked.

"Wow," Ghil said with a smirk, "What a shocker."

"Shut it," Rilova shushed as she turned her attention from the door to the desk.

"You're not seriously going to-" Ghil started.

"Yup," Rilova said as she pulled open the top drawer of the desk and began sifting through all the junk in it.

Ghil anxiously looked up at the entrance to the classroom fearing that at any moment someone would enter and catch them digging through the instructor's things. Hell, if they walked into this classroom it might actually be their things!

Rilova eventually produced a single key from the drawer. A simple unmarked blue tag hung from the ring attached to it. She went back to the door to try again. The key fit! Slowly she pushed the door open and stepped into the darkness.

"Come on!" Rilova said.

Ghil cautiously followed his friend through the door and into the back store room. He'd never been in there before and judging by the amount of dust covering everything inside he figured not many other people had been in there either.

Rilova reached for the light switch next to the door frame and flipped it. Nothing happened.

"Shit, the light's out in here," she muttered. She reached into her pocket and grabbed her phone and turned its flashlight mode on. A single bright white LED illuminated the space in front of them for a couple of feet.

"How big is this room?" Ghil asked peering into the darkness ahead.

"I have no idea. I can't see the back wall from here."

Rilova began walking into the room shining her phone's light on everything as she passed. She walked past several shelves of standard lab equipment before reaching a pair of filing cabinets which happened to be unlocked. She opened one of the drawers and started thumbing through its contents.

Ghil brought out his phone as well and turned on its light. He wandered a little further into the room than Rilova. While she was looking at files he started inspecting the contents of some metal racks. Most of it was the usual educational fare, if not a little outdated, but the further back he walked the more eclectic the items became. Old preserved specimens, geological samples, and other such things peppered the shelves. Ghil began handling some of the objects turning them around with his free hand while he held his phone in the other. Every few moments he'd hear a filing cabinet close and another one open as Rilova kept looking through them.

"Hey!" Rilova eventually said after a few minutes of searching.

"What is it?" Ghil asked.

Rilova walked back to where Ghil was and flashed him the manila folder she was holding. On its cover was the seal of the Office of Scientific Investigation, the OSI as it was known, with lettering underneath it reading "CLASSIFIED".

"I told you they were here," Rilova said grinning.

Ghil huddled close to Rilova and held his phone above the papers so they could read them, however just as Rilova was opening the folder they heard the handle on the door to the store room move. Immediately both students glanced at the door. Rilova stuffed her phone into her pocket while Ghil dropped his onto the floor and as the device made contact with the tile the shock caused the flashlight to instantly turn off. Ghil and Rilova ducked down where they were however as Ghil crouched down to search for his phone he bumped into the nearby shelves. Something fell off of them and hit the ground with a heavy thump.

"Be quiet!" Rilova said in a hushed whisper.

The two dinosaurs sat in the darkness as they heard the door to the room slowly creak open. Neither student said a word but as the two hid Ghil felt something wet brush up against his lower leg. He flinched, and a moment later felt it again this time at the cuff of his cargo shorts. Something was attempting to crawl into his pant leg. Ghil gasped and Rilova quickly wrapped her hand around his face to silence him.

"Is someone in here?" A voice called from the doorway.

Ghil squirmed where he sat as the wet mass slithered up into his shorts, reaching the edge of his underwear moments later. He frantically reached down to try and grab whatever it was that was touching him but the mass proved to be squishy and hard to hold. The mass breached his underwear and brushed up against his flaccid cock causing the dinosaur to exhale sharply into Rilova's hand.

A gentle flick echoed through the room. "God damn lights are out again," the voice said.

The mass inside Ghil's shorts slid along his length probing it as it moved. Ghil's legs flinched and he sucked in a breath of air through Rilova's fingers as he felt the head of his maleness become enveloped in a strange warmth. The wet warmth inched down his now half flaccid shaft and stopped at its base. Not a moment later Ghil felt something probe at the slit of his shaft. His body tensed up as the thing probing his shaft quickly entered it, the slippery tendril effortlessly invading the student and disappearing deep within him.

Footsteps could be heard as the person inspecting the room stepped inside.

Ghil's heart raced as he felt the mass enveloping his cock begin to tighten around it and squeeze it. The tendril reaching down inside his length began to pulse and a couple of seconds later the dinosaur noticed a strange warmth building inside his testicles. Ghil wanted so badly to cry out for help but knew that getting caught back here would surely result in expulsion. He bit his lower lip hard enough to draw blood and gritted his teeth has his body was assaulted until finally the two students heard the person exit the room and the door close behind them.

Rilova dropped her hand from Ghil's face causing the dinosaur to shudder and let out a sigh.

"What the hell was that all about? Were you trying to get us caught or something?" She asked angrily.

"No! I- uh- I-" Ghil stammered.

"Is something wrong?"

"No," Ghil answered hastily while shaking his head.

"Come on, let's get out of here before we actually get caught."

Rilova stood back up while Ghil awkwardly shuffled to his feet. Together they approached the door and Rilova opened it just a crack to peek through.

"The coast is clear. Let's go," she said.

As they left the classroom the familiar chime of Ghil's watch rang out.

"That's my cue," Rilova said. "Text me! We should hang this weekend!"

"Sure, okay," Ghil stammered out noticeably distracted.

Rilova gave Ghil another quick hug and hurried off toward her next class. Ghil, on the other hand, immediately rushed to the nearest bathroom.

Ghil barged into the restroom and went straight to the farthest stall in the back. He threw his backpack down on the ground next to the toilet and hurriedly fumbled with the buckle on his shorts. He yanked down his clothes and jutting out from his crotch was an organ that Ghil did not recognize. His shaft was covered in a sleeve of blue flesh that rode all the way up to the base.

After what felt like an eternity he worked up the nerve to touch it. The blue flesh was soft. It had a little give to it. Ghil gently held his shaft and squeezed it. Through the blue layer on top of it he could still feel his actual shaft inside. He tugged on it slightly but the mass enveloping his length would not budge. He tugged a little harder and his hand slipped causing the dinosaur to shudder reflexively. The attention being paid to the mass on Ghil's shaft caused it to shift a bit. Ghil gasped slightly and his cock gently flexed in response. As it flexed Ghil could feel the tendril still buried inside his length. The dinosaur reached down and palmed his balls and groaned a bit as a dull swelling sensation finally registered.

"What is this? What's happening to me?" Ghil said to himself, his thoughts racing wildly.

For the first time in Ghil's career as a student he skipped his final classes of the day. He genuinely did not care about the absences. He was frozen in fear in the bathroom stall unable to take his eyes off of his changed anatomy. A million scenarios passed through his mind and none of them seemed like a plausible way to handle the situation. This was unbelievable. This was crazy. This was also somehow perverse.

Eventually Ghil did have to go home. Ghil pulled his shorts back up and tucked his strange maleness back into his underwear. He collected his things and drove home.

When Ghil arrived home he was still very much a mixture of nervous and paranoid and barely had much of an appetite when it came time for dinner. He spent the rest of the night in his room continuously mulling over what, if anything, he was going to do about what happened at school.

His phone jingled several times throughout the night as Rilova sent him text messages but Ghil didn't read any of them. At around 11 PM his phone started to ring, it was her.

"Hello?" Ghil said as he answered the phone just before it was about to go to voicemail.

"Hey, is everything alright? I've been texting you all day," Rilova asked.

"Uh, yeah. I've just been, uh, really into that new RPG. I wasn't paying attention to my phone."

"Loser. Well anyways I was trying to let you know that my roommate is going to spend the weekend at her parents' ranch. She invited me but I'm not going because there's nothing to do out there and my phone doesn't get any signal either."

"Oh," Ghil replied simply.

"So if you wanted to come over and hang. I'll have the place to myself," she said with a giggle.

Ghil forced a slight laugh in response. "Sure, that sounds good. I'll call you tomorrow."

The conversation ended and Ghil laid back in his bed still wearing the clothes he had on earlier that day. He sighed and roused himself to put his sleep clothes on. As he took his shorts off he couldn't stop himself from inspecting his cock for what had to be the sixth or seventh time that night. He squeezed his length again and could still feel his actual shaft inside the mass though the feeling had dulled greatly since that afternoon. Ghil noticed he was actually starting to feel the outside of the mass almost as if it were his own skin. He cupped his balls and held them in his hand. They felt heavy.

He threw on his sleepwear and laid in his bed. Despite all that had transpired he somehow was able to eventually drift off to sleep. As he slept his body continued to change.

Sunlight beaming through the mini blinds in Ghil's window woke him from his sleep. Ghil tossed and turned in his bed and after a few minutes got up and made his way to his bathroom. A night of rest somehow caused Ghil to forget about what happened but as he entered the bathroom to start his morning routine he was greeted with a reminder.

Ghil nearly shrieked as he looked down at his shaft. The blue mass around it now had a definite form. It had a spade-shaped tapered end and every inch or so behind it was a subtle ridge in the flesh. Where the mass met his skin at the base of his length there was now no seam, the blue flesh had merged into his scaled skin. As Ghil felt his shaft he realized he could no longer feel his member inside of it but he could feel every inch of the ridged blue flesh. He could even feel his own blood pumping through it. The mass had completely fused with him and absorbed his shaft. This was now his cock.

But that wasn't all. Ghil looked down past his shaft at his balls. The skin of his scrotum was still the same but it was stretching to contain its contents. Each of his orbs had grown to the size of a very large egg and hung heavily under him.

Ghil was still terrified of what was happening but in the back of his head a part of him couldn't help but like what it saw. His cock had grown a couple of inches, his balls were heavy and full. For a computer nerd he didn't have a bad set of tackle now, but there was still a more pressing matter. He had to use the restroom.

Ghil wasn't sure what would actually happen as he aimed his semi-morning-stiff blue shaft at the toilet but ready or not he was about to find out. Several moments passed as Ghil tried to force himself to go and after a few seconds a completely normal stream of piss emerged from his altered cock. The dinosaur breathed a sigh of relief as he cleaned himself up and got dressed for the day.

As noon approached he called Rilova and spoke with her a bit. She invited him over again and Ghil obliged, driving over to her apartment after their conversation. Rilova answered the door in a crop top and skinny jeans that accentuated her hips. Ghil swallowed audibly as he saw her standing the doorway. He knew what "my roommate isn't home" implied, this wasn't the first time. He learned that a couple of years prior when the phrase was still "my parents aren't home".

He invited himself in giving Rilova a hug as he passed her. Rilova went into the kitchen to get a couple of cans of soda before nodding her head toward the hall leading to her bedroom and motioned for Ghil to follow her. The usual "nobody's home" afternoon played out over the course of the next couple of hours. Rilova's TV was on but nobody was watching it as the two dinosaurs were more preoccupied with goofing off on Rilova's computer. Ghil had brought his graphing calculator with him and had fruitlessly tried to copy some of the games he'd downloaded onto it into Rilova's computer but as usual nothing appeared on the screen when he plugged it into the tower.

"Don't worry about it," Rilova said. "I don't even have a thing to play them on yet anyways."

She'd been sitting on Ghil's lap for a while and leaned back to kiss him on the cheek as she spoke. She stood up from her seat and playfully tugged Ghil's arm.

"Come on, I'm bored," she whined. "Let's fool around some."

Normally hearing those words had a certain effect on Ghil, but this time he could feel his anxiety building. Worried thoughts began welling in the back of his mind. Nonetheless he rose from the computer chair and turned toward Rilova's bed but as his gaze scanned the room his eyes locked onto something he didn't notice earlier. Sitting on Rilova's nightstand was the folder of classified documents from the biology store room.

"Wait a minute did you seriously steal those papers?" Ghil asked pointing toward the table.

"Uh yeah," Rilova replied. "I wanted to read them."

"Isn't that like a felony or something? That absolutely has to be against the law."

"Chill out, Ghil. The folder is nearly a hundred years old. I doubt anyone will ever notice it's gone. Besides I can always sneak back into the storage room and put them back."

Ghil paused for a moment.

"Hey, uh..." he started. "Was there anything in there?"

"What do you mean?" Rilova asked in response.

"Like, about aliens. Did it say anything about alien, uh, you know, lifeforms?"

Rilova laughed. "Well look at you, it seems like you were actually curious about this all along Mr. 'There's No Such Thing'."

"Uh, yeah..." Ghil said, his voice trailing off. "So... was there?"

"Well if you must know the information is inconclusive. Most of the papers in the folder have been censored so I couldn't glean anything from them. But they were definitely studying something strange that's for sure."

Ghil frowned and slowly sat down on the edge of the bed. Rilova slinked over and gave him a light kiss on the lips. Ghil tried to reciprocate and get into the mood but his mind was elsewhere.

"Is something wrong?" Rilova asked.

"Uh... I..." Ghil paused, lost in thought.

"You're not actually mad about the folder are you?"

"No! It's just, something happened and..."

A puzzled look fell on Rilova's face. "Well," she shrugged. "Maybe I can take your mind off of it for a while."

Ghil didn't say anything in response but he shuddered as Rilova palmed the outside of his crotch through his clothes. He knew what was coming. His underwear already fit a little tighter just holding his new package but he could feel the cloth suffocating his cock as it began to throb and firm up. As Rilova scooted in closer she reached down with her other hand and began to undo the buckle on Ghil's pants, though after a few seconds Ghil started to panic.

"Ril, wait!" He said.

"What's gotten into you, dude?" Rilova asked.

"I dunno, it's complicated, but-"

Rilova cut Ghil off with her laughter and went right back to tugging on his clothes. Ghil squirmed a bit but ultimately with a few tugs Rilova was able to pull his pants down slightly and Ghil's blue member flopped out of his underwear. Rilova immediately let go of Ghil's clothes and gasped.

"Ghil... what the fuck?"

"I can explain. I think," Ghil replied.

Rilova didn't say anything, her gaze was locked on her friend's bizarre shaft.

"Something happened. Yesterday. In the store room."

"What? When?"

"When we hid from whoever came in to see why the key was left in the door. Something... attacked me."

"And it did THIS?" She asked.

"It like... latched onto me. I think it injected something weird into me too. It's why I was making so much noise while we were hiding."

Rilova again fell silent, staring at Ghil's crotch.

"Does it... hurt?" She finally asked.

"Uh... uh, not really?" Ghil said, his face flushing.

Rilova hesitated for a bit. This was absolutely weird to her but she found her curiosity slowly building. She moved closer to Ghil and reached down to grab his shaft holding it gently in her hand. As her fingers daintily wrapped around it she felt the organ throb in response.

"Does it feel good?" She asked, emphasizing the word "good".

Ghil gasped lightly as Rilova touched his shaft. "Y-yeah sorta..."

Rilova grinned and bent down toward Ghil's shaft. She experimentally licked at the tip of the blue member before taking it into her maw once again feeling it throb powerfully in response to her touch.

Ghil shivered and moaned as Rilova's warm tongue teased his length. The young dinosaur leaned back and propped himself up on his elbows as Rilova took ever so more of his flesh into her mouth. Ghil sighed as he started to enjoy what she was doing. Ghil could swear that whatever had happened to his cock had made it even more sensitive as he was feeling Rilova's tongue in ways he never had before. Ghil's eyes slowly lidded as he savored the moment, though as Rilova suddenly stopped he looked up.

"What are you doing?" He asked.

By now Rilova had unbuttoned her jeans and slid them off along with her panties. All she was wearing was her crop top.

"I want to feel this inside of me," she said as she turned around and got down onto her knees and hands.

"This thing??" Ghil asked nervously. "But... I uh, do you have any more condoms?"

"I don't even care," Rilova said pushing her rear end toward Ghil's crotch.

"But-"

"Come on Ghil," Rilova interjected. "Fuck me with your alien cock."

Ghil was taken aback by how forward Rilova was being as she'd never acted like this before. He was apprehensive about the whole act let alone not having any protection, but as he looked down at Rilova's ass and admired the inviting look of her petite little vagina he felt a sudden desire build up within him that he couldn't explain. Her emphasis on "alien cock" aroused him in a way he couldn't explain.

He rose to his knees and gently held Rilova's hip with one hand. With the other he held his swollen shaft and pointed it at her entrance. Slowly he pushed himself forward and watched as the spaded tip of his cock spread Rilova's lips apart and let him inside. Ghil exhaled lightly and slowly thrusted into her feeling her warm walls wrap around the first couple inches of his shaft. Rilova vocalized a gentle moan and rocked her hips back against Ghil sliding more of his member into her. Ghil placed his free hand at Rilova's other hip and held onto her as he pulled himself back and thrust forward again feeling each of the subtle ridges of his cock push into his girlfriend and spread her open.

Rilova trembled and tensed up, her inner walls tightening up around Ghil as he pushed deeper into her.

"Am I hurting you?" Ghil asked worriedly when he felt Rilova's body tighten.

"No... you're fine," Rilova said with a sigh. "You're just... really big now, and I'm not used to it."

Ghil smiled at Rilova and leaned down to kiss her on the neck.

"She called my cock BIG," he thought to himself. Rilova's comment lit a fire inside of Ghil that he didn't know he had. His worries about his bizarre altered anatomy had all but vanished now. He was able to pleasure his best friend in a way he never could before. She was enjoying this, he could tell. He was enjoying this now too.

Ghil held Rilova's hips a little tighter and pushed himself further inside. As his cock probed ever deeper into Rilova the young dinosaur squealed, her warm velvety walls twitching and pulsing all around Ghil's shaft.

"Oh my god, Ghil, don't stop," Rilova uttered, her voice seeming to trail off.

Ghil obliged and grabbed Rilova tightly as he pushed the rest of his engorged member into her. Rilova shuddered as Ghil slammed into her and curled her toes as an orgasm jolted through her body. She cried out in pleasure as Ghil repeatedly plunged his cock deeper into her than he'd ever been able to spreading her canal out and filling it completely.

"Ril... I'm about to cum," Ghil said between grunts, his pace not slowing at all.

"Shoot it inside me," Rilova said turning to face Ghil with a grin.

The sultry look on her face was all it took to push Ghil over the edge. He cried out and moaned in pleasure as he pushed himself as deep into Rilova as he could go. His mutated cock throbbed powerfully with every flex releasing a torrent of thick blue cum that filled what little space was left in Rilova's vagina and splattered against her cervix. He grinded his crotch against Rilova's backside as he rode out his orgasm feeling his swollen balls churning as they dumped their corrupted contents.

Ghil sighed and collapsed atop Rilova absolutely spent. The two dinosaurs rolled onto their sides on the bed holding each other in a spooning embrace. Ghil nuzzled and kissed at Rilova's neck as she sighed and leaned into her friend's embrace.

"That was amazing," Rilova said finally breaking the silence.

Ghil chuckled and shifted on the bed withdrawing his softening cock from Rilova. As he pulled out of her a generous amount of his seed spilled out of her folds onto the bedsheets. Both of them gasped when they looked down at it and noticed its strange color.

Ghil shook his head. "I don't know why I'm surprised."

Rilova reached down and ran her index finger through the tainted seed. She rubbed her finger and thumb together to feel its slickness before experimentally licking her finger clean.

"So uh, any good?" Ghil asked with a laugh.

"I think I like your alien cum more than the regular stuff," she replied with a grin.

Ghil leaned forward and gave Rilova a light kiss.

"This is all too weird," he said.

"It is, but I like it," Rilova replied. "This is our little secret. I guess we both stole something from the storage room yesterday."

Ghil rolled his eyes at the remark. He wrapped his arms around Rilova and held her close to him, one of his hands finding its way down to her belly to caress it. His mind wandered wondering what would happen now that he almost certainly impregnated her with the alien seed his body was now producing. Inklings of worry started to sow in his mind but he found them quickly quashed with the growing realization that making Rilova a vector for alien life was starting to turn him on. He could feel his shaft starting to firm up again already just at the thought. He was certain they'd have another round before the day was over but for now Ghil was content with cradling Rilova close. Time is a commodity, and Ghil and Rilova had plenty of it.
