SPH-THEMED EROTICA STORIES

We plan to keep much of our erotic fiction grounded in reality. Though most definitely embellished. However, hubby and I also love when things get weird! With that in mind, we’ve decided to create an ongoing series of stories with a Multiverse theme! Most of this series will be one-shots. The overall theme is that the Multiverse contains an unlimited number of realities and alternate timelines.

The only constant? Katie always ends up cuckolding Kyle! With alternate versions of our Dominant Big Black Bull, Dante, as the master manipulator and villain pulling our strings!

This particular story has a Twilight/Tales from the Crypt feel. No happy ending here! A beautiful busty college girl hopes to become the top lab assistant for the brilliant, tall, dark, and handsome Professor. To help give her an advantage, she convinces her shy, nerdy boyfriend to volunteer as a test subject for an intense semester-long sexual research study. Unfortunately for him, once he signed the contract, he learned that he would be required to endure 24/7 chastity all semester long! But there’s much more concerning research going on in another part of the facility…

This story contains the following: Chastity, bondage, SPH, big tits, BBC, Cuckolding, Edging, Endless Tease & Denial.

Cuck Multiverse: Katie always cucks Kyle!

Trapped in a Tease & Denial TimeLoop

***********

Kyle looked at his beautiful busty girlfriend, Katie…with a feeling of lustful frustration that seemed never-ending…

He was lying naked in a lab, reclined back on a medical stirrup chair. His body was strapped down tightly at multiple points by medical restraints. His legs were spread and strictly secured in the stirrups. He had a large ball gag in his mouth, pulled back behind his teeth, with the straps straining at the corners of his mouth. But the worst part had become the bane of his existence. His penis was locked into a highly advanced small tight chastity cage.

His girlfriend Katie had gotten him into this. Literally, she was the lab assistant overseeing him. She was standing nearby, arranging and double-checking medical equipment. She was wearing a tight, low-cut white minidress and a nurse’s uniform. In this particular section of the research facility, all the lab assistants seemed to wear them. Katie seemed to be the most shapely of them all. She was a short brunette with an amazing hourglass figure that never failed to wow him. He was in awe of her, still amazed that a shy nerdy nobody like him had managed to become her boyfriend.

Of course, his insecurities had also led him to agree to anything and everything to make her happy, which is why he was here.

The large research facility was housed at, and under, the University that Katie and Kyle attended. They apparently had all sorts of studies ongoing here, separated into different sectors and labs. It was run in conjunction with the government. Katie had even heard rumors that a sector in a sub-level below was conducting highly secretive research on “timey wimey” stuff. Sounded completely made up to Kyle. But that’s how secretive government research went, he supposed. There’d always be someone inventing gossip about what could be going on behind secure doors.

But the section Katie worked in was for sexual research studies, run by the “brilliant” and extremely popular Professor Dante. He was a tall, muscular black man with a deep, commanding voice and a no-nonsense demeanor. He was very handsome and popular with all the young women attending the university. Katie, too, had an apparent crush on him. But since she had been accepted into the program, her primary interest was to become one of his personal lab assistants, with the hope of eventually becoming his top research assistant.

In that pursuit of hopes and dreams, a plan had formed in Katie’s mind at the beginning of the semester. Professor Dante was looking for male college students to volunteer to be test subjects for the semester. He had specifically mentioned this to all of his pretty young lab assistants. Knowing that they would be able to get the word out around campus. He had even insinuated that convincing their boyfriends to sign the volunteer contracts might earn the girls a better shot at getting a research assistant position.

So, of course, Katie had gone to work immediately on convincing Kyle to sign the dotted line. Before she was even finished batting her pretty eyelashes at him, he had signed up without even reading the contract. Soon after, she brought him into the facility. He found himself contractually obligated to fulfill the semester-long conditions; unfortunately for Kyle, that turned out to be a study on the mental and physical effects of 24/7 male chastity.

He hadn’t even had a chance for the two of them to have one last sex romp at the dorms. At that same first visit to the Facility, she was securing the high-tech prototype chastity device to his package. The Professor didn’t even give him a couple minutes to masturbate first, even though Kyle had practically begged the man. His only reply? “We’re not contractually obligated to allow that.” He didn’t even bother to look up from his tablet when he said it.

So began Kyle’s semester of sexual denial. The cage tech had all sorts of features for monitoring and security. If he tried to tamper with or tug on it at all, he’d get a warning sound and an automated text. Katie would get that warning text too. If he so much as “shook it more than twice” at the urinal, he’d get a text from her to stop fiddling with it. The damn thing was even self-cleaning! When they said the device was intended to be worn 24/7… they meant it.

To be fair, the amount of time he and Katie spent alone together in the dorm room increased considerably. She had been beaming when they left the facility together, a big happy smile across her face. She had wrapped both her arms around his arm, so proud to have such a loyal boyfriend. Willing to sacrifice so much for her… for so long. For so very, very long…

He honestly worried that she would lose interest in him now that they couldn’t have regular sex. But Katie had practically ripped his clothes off of him as soon as they got back up to the dorm room. He learned very quickly just how painful attempts at erections would be while inside the small, confining chastity cage. Having a thick, busty brunette ride your face tended to have that effect. On the bright side, his oral skills increased dramatically as the days rolled into weeks. Katie even mentioned that she included his progress on that in the research documentation.

The chastity device was even able to monitor his erection attempts using sensors inside the cage. It was a bit disconcerting to know that pretty young lab assistants working a late shift at the facility were getting reports on his dick and pressing against the top of the cage in a vain attempt at achieving a hard-on.

But most of the time, it ended up being Katie anyway. The longer the semester dragged on, the more late shifts she had to spend at the Facility rather than with Kyle. It sucked. But he was proud of her. Apparently the study was pretty groundbreaking. Any time Katie returned early in the morning, looking disheveled and exhausted, Kyle would ask how the research was progressing. But Katie wasn’t allowed to disclose most things. She would simply tell him that something at the Facility had turned out even bigger than she had suspected. Kyle was happy for her. That sounded like a pretty huge deal.

Meanwhile, Kyle had been learning the woes of this particular prototype. After only a week, they found he was losing sleep because of his body trying to get erections while sleeping. They adjusted with pills to help until they could add the meds automatically through the cage. After about 2 weeks of chastity, he was awoken in the middle of the night by a harsh shock to both his cock and balls. While pre-cum leakage became an almost constant issue, the sensors only measured the amounts and virility. But if the test subject got close to releasing an actual load of semen, the cage and base ring would both apply a shock to stop the release—no more intense nocturnal emissions. Kyle’s body seemed to adjust to this eventually somehow. Precum leakage increased, which decreased his body’s need for larger emissions all at once. At least, that’s what Professor Dante told them…

Admittedly, the actual research side of it wasn’t that time-consuming for Kyle. He simply had to come in to the Facility one scheduled day a month for a thorough check-up. That one day per month was very long, though. And pretty much every part of that long day was invasive and humiliating.

Upon arrival at the facility in the early morning, he would have to strip and shower. He would remain naked until he was cleared to leave the Facility later that night. The cage became his only attire, other than the restraints.

Before those restraints were added, he first had to sit through a session with their sector psychologist. She would ask him all sorts of embarrassingly personal or sexual questions. And about how he was mentally adapting to day-to-day life while caged. And the progression of difficulty as the semester went on. It was difficult to concentrate during these sessions. It didn’t help that the psychologist was a tall, beautiful woman with long black hair. She always had it up in a high ponytail. She had a very clinical demeanor. Yet she always seemed to wear tight, low-cut blouses, form-fitting pencil skirts, and ridiculously high heels. That put Kyle’s gears in motion. But once he saw the uniforms Professor Dante had given Katie and the other lab assistants to wear…

Either the Professor was making interacting with them intentionally torturous for the test subjects. Or he was using his status over them all to entertain himself. Kyle believed it was most likely both.

It didn’t help that the man seemed to be endlessly arrogant. He talked down to all his assistants and test subjects. But for some reason, all the assistants continued to treat him like he could do no wrong.

Kyle was not fond of Professor Dante.

**********************

Once the psychologist session was over, Katie would come in and escort Kyle to the lab. They would collect blood and urine samples. Then every test subject was required to spend the rest of their day restrained in a medical stirrup chair. This even included being ballgagged. Supposedly to keep them from accidentally biting themselves if any of the more invasive tests caused more pain than usual. Katie had told him that the assistants had all been given these exact restraint orders directly from Professor Dante. He had given the women strict orders to maintain and enforce these restraint rules at all times. Until the test subjects were cleared by him to leave the Facility. The insinuation was that any failure to enforce these strict guidelines could result in the lab assistant’s dismissal from the entire program.

So, understandably, Katie had warned Kyle that she couldn’t be seen to give him any special treatment. He begrudgingly accepted that this would be a monthly trial he’d simply have to endure. It wasn’t like he had any choice.

After Kyle was fully restrained on the medical stirrup chair and ballgagged, Katie would usually leave the lab for several minutes. Again, she’d never tell him details on why. But he assumed that she was required to check in with the Professor. It also seemed intended to give the test subject time to calm down and accept the reality of being so thoroughly restrained. Even knowing it was coming, the helplessness was always pretty disconcerting.

Katie would eventually re-enter the lab. She never talked much during these day-long checkups, other than necessary communication with the subject or the Professor himself. Kyle knew that she wanted to maintain strict professionalism at all times while onsite. Every inch of the Facility was under constant camera surveillance.

So she would only ask the subject yes-or-no questions. He was gagged, but could nod a yes or shake his head no. She would verify that no restraints were cutting off circulation/etc. for safety. Occasionally, Professor Dante would enter the lab himself and run Katie through some questions, data, or a verbal reminder of rules. He made a point of never addressing the subjects directly. It made Kyle feel a bit dehumanized, like he was just some background object in the room.

Katie would spend about an hour running tests on the chastity device itself. She triple-checked any external connections. During the first three monthly visits, this was the only time the cage was temporarily removed. They had to check and verify all the internal sensors inside the cage itself. But apparently they had made great progress with the tech itself. So every monthly visit since, poor Kyle didn’t even get a break from the cage during the checkup. The cage even measured his penis dimensions for possible changes. The idea that could be happening at all greatly concerned Kyle.

As for his testicles, there was no doubt at all about the physical changes to them. As the months of being locked had progressed, Kyle’s balls had grown slowly but steadily more swollen and sensitive. Katie was also required to take monthly measurements of these changes, which she did by hand during the checkup. She even had to use some pointy (but not sharp) instrument to basically poke all over his balls and sack to test sensitivity changes and pain tolerances. Kyle always dreaded that part. All he could do was bite down on the rubbery ball gag and endure it. He could always tell that Katie was doing her best not to look at his face as she heard his grunts of pain. She documented any and everything diligently. Needless to say, after months of total denial, Kyle’s balls looked and felt like they were beyond their limit.

Then came the next humiliating test for Kyle. Katie had to check on his prostate. She would adjust the medical chair and stirrups as needed to position him correctly for the required access. She would always lube his sphincter thoroughly, then use her gloved fingers to slowly loosen up the entrance manually. Then she would slowly but methodically push a small buttplug past his ring and into his anus. He always hated the sound of those gloves of hers snapping as she pulled them off and trashed them once the plug was left inside to force his ass to loosen up. Katie would again leave the lab. This part was usually one of the longer waits. Kyle would lay there in the chair with the stirrups in the air, awkwardly biting down on the gag as his anus tried to adjust to the pain of temporary resizing.

********************

During this final, end-of-semester visit, something new and unexpected happened.

After what must have been a dozen minutes or more, he heard a deep voice outside in the hallway. It sounded like Professor Dante. This was confirmed visually soon after. These labs were located in an underground sector. But they had a couple of windows that were connected with one of the side outer hallways. These windows had a slider that shifted from opaque to completely translucent. Or to a variable in between those two opposite levels. Currently, these seem to have their sliders set to the halfway point between translucent and opaque. So they appeared as a glass of white fog. You couldn’t see detailed features, but the general appearance of people that walked by was more distinct the closer they were to the glass.

This particular lab’s windows faced a quieter side hallway with virtually no traffic. So Kyle was surprised to hear the voice and see a foggy shadow on this side. Then he saw the tall dark figure of what was obviously Professor Dante, as his back seemed to be pressed against the glass. Kyle glanced over and noticed a pair of small white hands appear near the glass, seemingly holding the Professor’s hips.

In annoyed disbelief, Kyle began to hear a wet slurping sound. It was repeated and constant.

Kyle’s annoyance slowly shifted to resentment as he heard the Professor let out deep, low moans. That arrogant son of a bitch was out in that side hallway getting a blowjob from some intern! Maybe even from one of his many pretty lab assistants!

Kyle tugged at his restraints pointlessly. He couldn’t believe he was stuck enduring all semester with no sexual pleasure at all. Several guys from the University were. All for the eventual benefit of this man’s research study. And he had the nerve to be getting his dick sucked… while he was supposed to be overseeing these checkups?! This was bullshit!!!

As he was forced to listen, Kyle heard the slurping noises speed up. Whoever the giver was, she was very enthusiastic. Kyle’s small locked penis was twitching and attempting to swell inside the tiny cage.

He pondered reporting this to the University once he was done here today. The guys suffering through all this denial didn’t deserve to have to put up with the Professor flaunting this in their faces.

After several minutes, Kyle heard Professor Dante let out a deep growl of satisfaction. He was obviously cumming. His orgasm lasted for possibly 10 seconds or more. The woman’s small hands looked to be gripping the Professor’s asscheeks. From that, combined with the continual sucking and slurping sounds throughout, it was apparent that the mystery woman was swallowing the man’s entire load.

Kyle missed the pure heaven that he remembered from the last time Katie had done that for him. It felt like a distant memory now. From before this damned cage had taken over his sex life. Katie had never been crazy about giving head, so she didn’t do it often. But she had reluctantly done so for Kyle a couple of times throughout their relationship. It’s all he could think about now. He felt his little caged penis throb uselessly.

With the relaxed sigh of satisfaction of a man who just got his dick sucked to completion, Professor Dante wandered away from the foggy window. Kyle had to lie there, fuming with resentment, to rest. A few minutes later, Katie finally came back to the lab.

“Ok, Subject 13, let’s check and see if you are prepped for the probe.”

Katie snapped on a new set of latex gloves as she approached Kyle. She reached down and gently tugged at the buttplug. She slowly worked it out of his ass, pulling it out with a small wet popping noise. Then she pulled a med cart over and lubed up the probe.

Kyle laid his head back and sighed. He wished he could tell her about the bullshit that he had just been forced to witness.

Katie leaned in just a bit, letting him know she was about to begin. Kyle caught a brief scent in the air. It was a smell like cum. Dammit, his pre-cum must have oozed down past his balls and onto the buttplug while it was inserted. Kyle hoped Katie didn’t think he was perving out about the plug. This whole thing was so damn embarrassing.

Katie then pushed the long probe into Kyle’s ass. He closed his eyes and gritted his teeth against the gag. She was slow and gentle with it, but methodical. She looked to the side at the small monitor on the med cart, watching as it showed her the view inside Kyle. She slowed and then stopped the insertion before it reached Kyle’s prostate. She held it there while the instruments automatically took readings and measurements. She made a point to get as close to his prostate as she could. But she avoided actually touching it, as that could affect the results, as well as initiate unwanted release of semen.

At that moment, Kyle wished she would accidentally press the probe just a bit further. He was almost certain that one brief stimulation would be all he needed at this point.

But Katie eventually eased the probe completely back out of Kyle. He felt that his ass was gaping open. But he knew that his sphincter would slowly readjust and correct itself. She snapped the gloves off again and disposed of them. She washed her hands and returned to lower the stirrups to a more comfortable position. As she did so, she gave his thigh the slightest touch of her hand. It was a subtle sign of empathy, but she kept a straight face.

“Ok, Subject 13. I’m all finished taking your readings and measurements. As always, we’ll need to wait for Professor Dante to do his analysis of all the data before we proceed any further. This wait could be a while. Even more than usual, actually. The Professor has a full schedule today.”

Kyle rolled his eyes and grumbled through the gag a bit, but Katie seemed to either not notice or just straight up ignore it.

“I’ve got to take the cart and instruments for cleaning, and then do my own documentation. Please just try to relax and rest. I’ll be back in about an hour to check on you.”

At that, Kyle rested his head back against the med chair again and tried to nap to make the time pass more quickly.

 

 

With a restrained jolt, Kyle was startled awake by a noise. He wasn’t sure how long it had been since he’d nodded off. Disoriented, he glanced around the room. The loud sounds drew his attention to the same fogged window as earlier.

The tall, dark, unmistakable shape of Professor Dante was at it again! But this time, a woman was closer to the glass. Kyle watched as a woman’s waist was lifted by two big black hands. Her thick white naked ass suddenly slapped against the fogged glass. Using those big muscles of his, Dante was holding her up, her back pressed against the fogged window. With a muffled moan of pleasure, the Professor had apparently entered her pussy. Slow and steady, he began thrusting up into her. The curvy woman had long brunette hair…

‘Katie?’ Kyle asked himself, ever so briefly. But then immediately shook off the thought.

Katie wouldn’t cheat on Kyle. They loved each other! Plus, if she wanted to get laid, she wouldn’t have convinced her boyfriend to get his cock locked up all semester. What kind of sense would that make? Besides, Katie’s priority is progressing her career. She didn’t start working down here to fuck some professor.

As the woman’s thick ass repeatedly slapped against the fogged glass as Dante was thrusting into her over and over, Kyle became furious. How dare he keep doing this shit!? How dare THEY?! If she were an assistant here, she would know what kind of study he is overseeing. Well… supposed to be overseeing. This guy was terrible. Kyle decided he would definitely report the Professor as soon as he got the chance.

But for now, Kyle was ending this. He let out a loud, muffled grunt through the ball gag. It was loud enough for the two of them to hear him. But the sounds and visuals didn’t stop. In fact, both people just burst out laughing. But they didn’t stop; they never even slowed down. Kyle grumbled loudly again and tugged at his restraints, but the couple just giggled together and continued in their pleasures. Eventually they both reached orgasm together at the same time. Dante let out a long, deep, manly, gravely grunt of release. The woman let out a muffled scream of ecstasy. It appeared that she may have put her hand over her mouth to muffle her own voice.

Their combined orgasms continued for quite a few seconds, while Kyle just stared at the ceiling. His little cock was straining against the cage walls. And he could feel the very slow but steady trickle of pre-cum slide down the front of his ballsack.

Once they were done, they both wandered off. Kyle wondered if that had been a different woman than the one who gave him the blowjob earlier. Or was it the same woman? What if Professor Dante was trying to make the rounds through all of his assistants and interns? Would he try to pressure Katie?!

Kyle huffed in determination. Once he got out of here tonight, he was putting an end to this ridiculousness.

Just then, the power went out. Kyle lay there in silence and darkness. A couple of seconds later, the backup generators powered up, and the emergency lights came on. A couple of minutes later, the main power finally came back on.

Kyle mused that perhaps the University had neglected to pay the light bill for this place. Maybe they found out that their study lead was down here fucking subordinates instead of doing his job…

*****************************

Several minutes later, Katie came back into the lab. She looked disheveled. Whatever was going on must have upset her. She checked on him and leaned in to quietly whisper to him. She let him know that something was apparently going on in the sublevel labs below them. That must be causing some power surges. But the Professor had been assured by the government admins that things were back in order down there.

Kyle wondered if that woman getting fucked in the hallway had been one of those ‘government admins’ that had assured the Professor. He’d sounded pretty damn assured.

Katie said she needed to go check on a few of the other lab assistants to make sure all was clear for our sector. But that she’d be back as soon as she could. Then Kyle was alone again…

****************************

Kyle guessed that about twenty minutes had gone by. Then he heard whispering voices. They were moving toward the foggy windows. What…The…Fuck… There was no way he’d try that again. Not while Katie was running around checking on the other assistants. He wouldn’t dare…

But Kyle was wrong. Professor Dante WOULD dare. And he DID for the third time that day.

Kyle listened as the two lovers seemed to giggle and peel off each other’s clothes. Then an audible messy makeout session began for quite a while. Kyle could see her long brunette hair. So it was probably the same woman as last time. Fucking hell, how much could these two need to fuck?! Kyle had gone months without, and these sexfiends couldn’t go an hour without getting off?!

Then suddenly, the Professor turned the woman around and pressed her upper body up against the foggy glass. Her huge natural breasts smushed up onto the glass. The type of breasts that are so very memorable. The type that Kyle had only seen on one woman in this building. The breasts he’d worshipped so many times. The breasts he’d recognize anywhere.

Professor Dante hadn’t just spent all day fucking some random lab assistant. Professor Dante had spent all day fucking Katie…

As Kyle lay there helplessly as the huge pair of tits smashed against the fogged glass over and over and over, his mind was a whirlwind. How could she?! How could she do this to him!?! How long had this been going on? Was the Professor making her do this? No, she’d been laughing and giggling. She WANTED this. But WHY?! Was it because he wasn’t free to fuck her himself? Had she become so desperate that she’d been seduced by another man? But she was the one who convinced him to sign on for this shit to begin with! Had she done all of this on purpose?! Had this all been some sick, sadistic trick from the beginning!?! Had she always been planning to use this time to fuck Professor Dante? Was he doing this shit with ALL of his lab assistants?? Were all the test subject boyfriends getting cheated on?! Was that the entire reason he was running this study!?! FUCKKKKKK!!!!!

Kyle bit down and yelled through the ball gag as loud as he could. He tugged and fought against the restraints over and over uselessly. For a few seconds, the breasts had stopped moving, and there was some whispering… then he heard the Professor let out a deep laugh and the thrusting renewed with much greater intensity. Katie’s almost perceptible cheek pressed against the fogged glass above her big breasts. Tears rolled from the corners of Kyle’s eyes as the loud fucking continued for several minutes. Eventually, the moans from both Katie and Dante reached a crescendo yet again. Just then, Kyle heard a hiss, and the glass shifted from fogged over to completely translucent. The Professor had intentionally given Kyle the full view just as they both were about to reach orgasm. With her arms pulled back behind her by Dante’s large, muscular arms wrapped around hers at the elbows, Katie’s face and big, beautiful breasts were on full display. Her eyes stared into Kyle’s as she began screaming in orgasmic pleasure. The orgasm went on and on. Kyle’s confused penis was held at its full limit inside the cage of torment that was locked onto him. The throbbing would not relent. At some point, Kyle glanced above and behind his girlfriend to see Professor Dante’s arrogant, evil grin, just as he shifted into a primal roar of satisfaction as he came inside of Katie one more time from behind.

The sadistic bastard winked at Kyle, then the glass turned completely opaque….

**************************

Kyle had remained there in naked restrained silence for quite a while. His blueballs were enduring a deep constant ache. Enough time passed that, despite never achieving any sort of release, his penis finally shrunk back down. The power surges occurred a couple more times. Each a bit longer than the last. Kyle was in a tormented daze.

Then Katie finally walked into the room. She was disheveled but pretended not to be. She acted like it was business as usual. Kyle wanted to yell at her, but he knew it was pointless. This woman had knowingly and enthusiastically betrayed him. Yet even now, he couldn’t stop thinking about how beautiful she was. But instead of making him feel so lucky and privileged to be with her, it agonized him.

Katie turned and looked at him ponderously for several seconds, then walked over next to him and wiped his tears away with the back of her fingers.

Then she spoke a practiced speech, “Congratulations, Subject 13! You’ve finally reached the end of your semester-long denial. As a representative of this Facility and of the University, I’d like to thank you for your long-suffering sacrifice for science. Of course, Professor Dante wanted to be here to thank you himself. But as you know, he’s a very important, VERY busy man!”

Kyle rolled his eyes and grumbled pointlessly.

Katie continued, “Now then, before you are released from this Facility… Your signed contract entitles you to one complementary semen release, to be performed by the lab assistant assigned to your case study. Before I leave to let the interns come in and release your restraints… would you like me to perform this manual semen release for you?”

She stood there in her tight, form-fitting, low-cut nurse uniform and high heels. Her perfect curves hugged, her big soft breasts spilling out the top, and her deep cleavage tormenting the man that at least used to be her boyfriend. Her expression was impossible to read. Kyle couldn’t believe any of this was happening. It was surreal.

But… the deep ache in his blueballs was crying out for relief. Sure, he could wait until he was out, then attempt not to injure himself while jerking himself off an entire semester’s worth of backed-up semen. Or… he could swallow his own shame and get to feel pleasure one last time from the busty beauty that he had believed was his.

Kyle closed his eyes in disbelief, then nodded a “Yes”.

Silently, Katie prepared, as if it were any other medical procedure. She snapped on a new pair of latex gloves and brought over lube. She used her own phone and held it close to the advanced cage-locking mechanism. It scanned it as if it were a QR code, and the cage unlocked. Had she always had that as an option?! Could she have released him whenever she wanted while they were back in the dorm room?!

Katie slowly pulled the tiny cage away from Kyle’s tiny shriveled cock. She didn’t bother with the base ring section. She took time to complete final dimension measurements. She verbally stated to her voice recorder that Subject 13’s flaccid penis had shrunken half an inch from when he was measured at the start of the semester. She asked the recorder out loud whether this change would be permanent.

Then she poured a small amount of lube onto the tip, and ever so slowly began to stroke Kyle’s penis. Starting with only one pinky finger. Even realizing that the release would have to be a slow process because of just how much semen was currently waiting inside his blueballs, Kyle still felt that this was an unnecessary tease.

Katie’s pinky finger wrapped around his penis and moved up and down ridiculously slowly. Almost immediately, his little dick stretched and hardened. She even stopped to take a measurement when he was at full erection. Kyle was thankful that at least it still worked.

She announced to the recorder that the fully erect measurement had shrunk by an entire inch, down to 2.5 inches in total length. Kyle’s eyes went wide, and he started questioning through the ball gag, but she ignored him. She reiterated to the recorder, now with greater certainty, that this change would most likely be permanent. And that perhaps it was a side effect of the cleaning solution used in the cages. She noted to compare this with the data from all the other subjects.

Kyle groaned in dismay, but Katie went back to using her pinky to stimulate his now permanently shrunken tiny penis.

A few times, she got distracted by notifications on her phone. She’d keep her gloved pinky against his meat, but not concentrate on moving it while reading whatever texts were coming through. Kyle desperately attempted to thrust his hips to continue rubbing against her pinky, but in vain. But he was still held too tightly by the multitude of restraints. Eventually, she’d go back to lightly stroking him.

This process went on for what seemed like forever. Kyle was hard as a rock, his tiny dick trembling. Sweat was rolling down his head and torso. She slowly switched from pinky to one index finger to cover more surface area. Minutes later, she added a thumb to this, to add a light gripping sensation. That’s as far as she progressed, but it was doing the trick. Kyle’s little prick was absolutely throbbing. He could feel himself nearing a climax. A climax that he had been waiting an entire semester to reach.

As Kyle was gasping for breath, sweat poured down him. A small pool of pre-cum had oozed out onto the medical chair padding beneath his swollen blueballs. He was so close… he was so very close!

Without even a glimmer of enthusiasm, Katie continued methodically. Then the sensors from the base ring at his balls put out a notification to her phone that he was nearing a full orgasm. With the most emotion she’d shown since re-entering the lab, she giggled that she had almost forgotten to disable the shock options. She corrected that, though, and continued.

“Ok, Subject 13. When the indicator on my app shows me, I’ll begin the 10-second countdown to your detected release. Get ready to cum!”

Kyle was in both heaven and hell as the final release was imminent. He couldn’t think of anything else. Not the study. Not the Facility. Not that bastard, Professor Dante. He couldn’t even bring himself to think about Katie. However, he stared into her ample cleavage, as the stroking continued to make her big natural tits jiggle.

“Ok, Subject 13… here we go! 10…. 9…. 8….”

Kyle was practically hyperventilating… he felt the room grow hotter.

“7…. 6…. 5….”

‘Sooooo close! Sooo fucking close!!!! OH FUCK PLEASE!!!!’ He saw a strange… effect… in the air around Katie. It almost looked like a ripple…

“4…. 3…. 2….”

‘OH FUCK OH FUCK OH FUCK I’m finally going to cum!!!! Oh FUCK OH FUCK OH….’

Kyle’s world went bright white…

****************

‘fuck???’

Kyle was startled in utter confusion. He still felt the utter lustful desperation that had been overcoming him a moment before. But his heart rate had slowed. He wasn’t sweating. He wasn’t breathing heavy. The deep ache in his balls had shifted to a surging pain as he strained against the restraints. His tiny penis had somehow momentarily gone completely flaccid. But then almost immediately stretched back out, throbbing like it’s never throbbed before… inside the tight chastity cage…..

Kyle’s mind raced. ‘Why was the cage back on?! HOW?!? Had he blacked out when he came?! But… there was no relief! No release! No release at all! No cum! WHY DIDN’T HE CUM?!?!?’

Kyle looked around and spotted Katie. She no longer appeared disheveled. She looked exactly as she had this morning when Kyle had first been strapped down to the medical stirrup chair. She was standing nearby, arranging and double-checking medical equipment.

Kyle’s still very much blue-balls pulsed in agony. He shook his head ‘NO NO WHAT THE FUCK HAPPENED?!”

Katie looked over at Subject 13 without reacting, as if nothing weird had just happened. It was like they were back in the lab at the beginning of the day.

…Kyle looked at his beautiful busty girlfriend, Katie…with a feeling of lustful frustration that seemed never-ending…

*****************

The entire day played out exactly as it had before. Hours of frustration and denial, after he had already endured all semester long. Katie and Professor Dante didn’t even seem to notice. Had Kyle fallen asleep in the lab and dreamed the rest of his day?! Was he losing his mind?!? What the FUCK was happening?!

At some point, Katie repeats what she had briefly mentioned about the “timey wimey” study underway in the sublevel below this one. Oh no…. Oh please no….

Everything played out the same. Kyle tried so hard to yell, scream, and protest. They even gave him just enough meds to slow his heart rate to calm him… but did nothing for the frustration or blue-balled agony. And he couldn’t manage to change any of the timing of his day. All the same timing… everything kept playing out the same…

The day’s end occurred just as it had before. Katie unlocked and removed the cage.

“Ok, Subject 13. When the indicator on my app shows me, I’ll begin the 10-second countdown to your detected release. Get ready to cum!”

Kyle was in both heaven and hell as the final release was imminent. He couldn’t think of anything else. Not the study. Not the Facility. Not that bastard, Professor Dante. He couldn’t even bring himself to think about Katie. Though he stared into her ample cleavage, as the stroking continued to make her big natural tits jiggle. NO NO NO! THIS CAN’T HAPPEN AGAIN! WHY CAN’T HE CHANGE ANYTHING?! WHY DOESN’T KATIE REALIZE AND HELP HIM?!?

“Ok, Subject 13… here we go! 10…. 9…. 8….”

Kyle was practically hyperventilating… he felt the room grow hotter.

“7…. 6…. 5….”

‘Sooooo close! Sooo fucking close!!!! OH FUCK PLEASE!!!!’ He saw a strange… effect… in the air around Katie. It almost looked like a ripple…

“4…. 3…. 2….”

‘OH FUCK OH FUCK OH FUCK I’m finally going to cum!!!! Oh FUCK OH FUCK OH….’

Kyle’s world went bright white…

****************

‘fuck???’

Kyle was startled in utter confusion. He still felt the utter lustful desperation that had been overcoming him a moment before. But his heart rate had slowed. He wasn’t sweating. He wasn’t breathing heavy. The deep ache in his balls had shifted to a surging pain as he strained against the restraints. His tiny penis had somehow momentarily gone completely flaccid. But then almost immediately stretched back out, throbbing like it’s never throbbed before… inside the tight chastity cage…..

Kyle looked at his beautiful, busty girlfriend, Katie, with a feeling of lustful frustration that seemed never-ending…

The End.
