S’Zira’s Lab Adventures I

S’Zira yawned and looked outside her room’s window, stretching her naked, curved body. For a teenager, she had developed a quite tight, but cute butt, as well sligthly larger breasts than average teenager, C-cup, almost to a D-cup. “Hmm, seems like another beautiful day.”, she thought and wagged her huge, fluffy tail around a bit. She quickly dressed up with pink panties and open whit button shirt as usually, before going to drink some coffee and eat breakfast with her brother. But this time he wasn’t there, and so wasn’t the fresh coffee. S’Zira noticed the note left on the table with the signature of her brother.

Hey sis! I had to go fix some machines for a friend, I’ll be back by the evening, or in few days. Oh, and could you send this one package for me? You can find it from the Lab 3, but please don’t touch anything else, okay?

-S’Zero

S’Zira sighed and threw the note to trashcan in her frustration from lack of coffee, then proceeded down to the basement, where her brother’s research laboratories were located. There she used her fingerprint to open the main door, which closed after her with a quiet hiss. She walked down the long corridor until she saw the Lab 3’s door and used her fingerprint again.

“Man, this is creepy place… I’ll never get used to it. Now, where’s that package?” S’Zira looked around until she noticed a brown box on the table with another note telling her to send it into the given address.

“Oh, that’s it? Well, I’m outta here.” She grabbed the box and was about to leave when something shiny and black caught her eye at the other end of a room. It looked like a tight latex suit hanging from a rack along with various equipment. Her curiosity peaked and she decided to take a closer look at it. She put down the package near door, and walked closer to examine the suit. In front of it on a table, was a small paper note and manual for the suit. She ignored the paper note and grabbed the manual, and after a minute or two of reading, she came into a conclusion that it was some sort of a bondage suit or something.

“Well, this is kinky thing…Hmm… S’Zero wont be back for a while yet… I’m sure he doesn’t mind if I test run it a little. Hehee.” She blushed and giggled a bit as she put the manual open on the table, forgotting the note next to it in her excited state.

She looked at the rack and took down the latex suit and examined it a bit. It was quite stretchy, black latex, which would cover her whole body, expect head, and there was small holes for her tail, as well her pussy and tailhole area. Around the neckline was thick leather collar with some D-rings. There was also thick leather cuffs in the ankles and wrists of the suit with O-rings.. She stretched it a bit, and amazed how far she could stretch it, but it also felt like it tried to return back to its original shape.

Licking her lips, S’Zira undressed her shirt and panties, placing them on the table. She blushed a bit as she noticed her nipples poking a bit from her fur. Opening the leather collars, she proceeded to stretch the suit’s neckline, and worked her legs and then rest of her body in it. After a few minutes and some struggling with the arm parts and her tail, she managed to wear up the suit. After a moment of fiddling with the collar around her neck, she closed it, and over the lock, she placed a magnetically locking plate with O-ring. Feeling that she couldn’t open the lock without matching magnetic lock, S’Zira moved around with the suit a bit. It felt somewhat tight, covering her body perfectly and showing her figure to smallest details. She run her paws down her body, feeling the rubbery surface, and touching her rubber-covered nipples. Feeling her sex, she was surprised to find herself getting wet down there.

“This sure is interesting feeling. Mm, what’s next?”

Waggin her still free tail, she proceeded to pick up fitting part for her tail. Picking up narrow collar with O-ring she could clip open, she tied it around her long fluffy tail tightly and then clipped it onto back of her collar’s D-ring. Tugging her tail around a bit, she confirmed her tail being tightly bound and not getting in the way.

Looking for the next item, she found an interesting looking leather harness. The area covering her crotch was inch thick and stiff. She was curious about the inner side; It had three ball-shaped plugs, two larger and one tiny one, which was on little longer base. Turning the harness around, she found two pipe vents where the bases of those plugs would be and one small power socket in the front. Examining the plugs again, she noticed that the one for her tailhole was little smaller, maybe 2 inches thick, while the one for her pussy must have been 3 inches at least. The tiny plug got her puzzled though, until she read the manual about it.

“Whoa! So it goes there… this is kinky suit!” She thought with a smile. She was really starting to get turned on.

Finding a tube of lube, she squirted little of it on her two rubber-covered fingers and raised her right leg on a chair. Rubbing her fingers against the crack of her tailhole, S’Zira shivered from the feeling of cold lube, before plugging her index finger inside her tailhole, finding little resistance. Pumping her finger in and out a bit, she enjoyed the feeling of rubber-covered finger inside her tailhole, before inserting second finger. S’Zira rubbed the lube around inside her tailhole, stretching it a little for the plug while purring.

Finally pulling her fingers out, she quickly took the harness and lubed the plugs. Bending the harness a little, she placed the round plug at the entrance of her tailhole and started slowly pushing. S’Zira felt her tailhole resist a little, but it stretched slowly and tightly around the ball plug, before it slipped completely inside her, the narrow base making sure it doesn’t slip out easily.

“Damn, that was tight… But it felt damn good.”

Panting a little, she bent the harness base little upwards, pressing the second ball plug against her pussy, but not pressing it in yet. S’Zira grabbed the tiny ball plug, which had long, wire-thin semi- rigid base. Guiding it to her uretha, she pressed the ball against the opening. Feeling the need to pee, she ignored it and slipped the small ball in, slowly pushing it deeper using the semi-rigid base. When she finally got it deep enough, S’Zira started slowly pressing the harness base against her crotch, slipping the ball plug inside her pussy and pushing the another deeper inside her uretha. She finally felt the tiny ball pop inside into her bladder, making her shiver from new feeling. The ball plug in her pussy was safely tucked in as well, so S’Zira fastened the harness around her waist and base of her tail tightly with series of magnetic locks. S’Zira walked around little again, feeling the pressure of the plugs inside her. She felt the heat in her pussy, making her even wetter. Walking back to the table with the remaining equipment, she licked her lips and looked over them. Only thing left was the mask made from same material as the suit she was wearing now. Looking left, she saw a strange-looking latex chair. It had normal armrests, then ones for legs with lockable O-rings sticking out from holes near the end. They were spreaded, like the another set of armrests that went up from sides of the chair. They had lockable O- rings near their ends, as well. The chair had also control panel in the right side of it. S’Zira also noticed the power cord and two rubber pipe plugs sticking out from the chair.

“Ah… I get it now. The plugs can be enlarged with air or liquids.” Licking her lips and feeling the rising heat in her pussy, S’Zira grabbed the mask and went over to the chair.

Looking over the chair once more, she decided to plug in the pipes and power cord first. Placing the mask over the control panel, she sat at the edge of the seat and grabbed the closest pipe. Pulling it closer, she plugged the pipe into the valve of the plug in her pussy. With a small hissing sound and a click, it locked into it. She even felt the ball plug in her pussy expans a bit. Grabbing the second pipe, she plugged it into the valve of her tailhole’s plug as well. Noticing the power cord, she examined it a bit. It was almost as thick as normal power cord, with just smaller rubber plug and some sort of locking mechanism in the end. Shrugging, she plugged it in its place too with a click.

Seating herself comfortably, S’Zira activated the control panel and started reading the options it showed.

Session length = XX hours, XX minutes Anal plug size = XS / S / M / L / XL Vaginal plug size = XS / S / M / L / XL Vibration = ON / OFF Randomize = YES / NO Startup in = XX minutes

Scratching her cheek, S’Zira considered the options for a minute, the pressed some buttons to get settings the way she liked.

Session length = 02 hours 00 minutes Anal plug size = XS / S / M / L / XL Vaginal plug size = XS / S / M / L / XL Vibration = ON / OFF Randomize = YES / NO Startup in = 15 minutes

She smiled and pressed the startup button. 15 minutes should be enough for her to get the mask and other stuff on, she thought. She decided to examine the O-rings she saw in the chair and found retractable leather leashes with those lockable O-rings in the ends. Pulling some slack on them, she clicked them onto her ankle cuffs. Checking the upper arm rests, she found similar set-up from there as well. Pulling enough slack for her hands to move around freely, she clicked them onto her wrist cuffs as well.

Picking up the mask, S’Zira examined it closer. It was designed to fully cover her head, and there was two pipe valves in the front. Checking inside, she found cock gag inside and noticed the small hole in the end of it. “Probably for breathing and eating.” She thought. Giggling, she thought about the eating part, if she were to remain here longer as a… slave or something. Looking around for the pipes, she found them hanging loosely in the left side of the chair, going behind it into some large device. Grabbing the pipes, she plugged them into their matching valves.

Getting even hornier, S’Zira decided to hurry up. She noticed the zipper behind the mask, but in the zipper was small metal locking plate. Similar ones were around the neck of the mask, total of six. Fingering her collar, S’Zira found matching set of small holes for them.

Figuring out everything, S’Zira pulled the mask over her head. With little fiddling, she managed to fit the cock gag into her mouth. It was apparently modeled after canine cock ,with the knot and all, which was effectively gagging her. Fastening the mask around her head, she adjusted her high ponytail going through the small hole from the beginning of the zipper, before zipping it shut, tightening the mask even more. S’Zira finally noticed how the mask somehow effectively nullifies her sense of hearing too, she couldn’t hear a thing from outside. Feeling little scared, she plugs the mask’s locking plates down to her collar, effectively locking it in place, until she opens the collar’s magnetic locks again.

Leaning back, S’Zira relaxes a little now in her latex prison, waiting for the countdown to end and her ‘torture’ begin in few minutes. Meanwhile, the small paper note next to the manual lies forgotten…

Repair note to self: Control panel short-circuited, system unstable. Use not recommended until parts are replaced.

While the control panel is counting down, small whirring sound is heard, followed by small spark from the control panel. With the spark, the settings changed.

Session length = 09 hours 22 minutes Anal plug size = XS / S / M / L / XL Vaginal plug size = XS / S / M / L / XL Vibration = ON / OFF Randomize = YES / NO Startup in = 5 seconds

At the moment countdown hit zero, the leashes tightened, spreading S’Zira’s legs and pulling her arms up. With a muffled yelp, she struggled against them a bit, finding them locked. Relaxing again, she waited for the the plugs to start. When nothing came for few minutes, she started getting worried. Did the machine fail or something? She decided to wait a bit longer. After quarter hour, S’Zira was trashing against her bonds to get free and check if the machine broke. Panting, she stopped to think how to get out of her current situation. There was nobody in the house until later today, she couldn’t scream for help; the basement labs were sound-proofef anyway. Her pondering was cut short by hissing sound and sudden expansion of her anal plug, though. Yelping from surprise, S’Zira arched her back a bit as the plug in her ass expanded longer, but not thicker. Slowly expanding, the plug became about 4 inches long and stopped. Then it started vibrating, while the plug in her vagina still remained same.

Squirming in her bonds, S’Zira’s thoughts were starting the get clouded by her lust caused by the small vibrator in her ass. Biting and licking the cock gag, she whimpered for the plug in her pussy to start soon so she could orgasm. It continued for few more minutes, then the anal plug went silent.

S’Zira stopped squirming as her thoughts cleared a bit to think about was going on. She didn’t get far, after a minute the plug started vibrating again, but along with it started the one in her bladder as well. S’Zira shivered a little from the sensations she was getting from the plug in her bladder, it was completely new to her. Then the anal plug went still again.

12 minutes later, S’Zira wanted to cry from frustration. The vibrating ball in her bladder was driving her crazy! Trashing against her bonds, she tried to rub the harness at least some way to get her release. She was starting to get sweaty and she was panting into her cock gag.

Another 12 minutes pass, and S’Zira really wanted to cry by now, when the plug in her ass became active again, and the hissing from plug in her pussy told it was starting up, too. Yelping from joy, S’Zira started enjoying the ride again while the plug in her pussy expanded. Its expansion continued until it was same size as her anal plug and started to vibrate.

It didn’t take long for S’Zira to reach her peak and orgasm hard, then second time as the vibration continued bit after that. Screaming into her gag, S’Zira trashed pulled her bonds and arched her back as she came. Panting into her cock gag, she wondered what was coming up next, until she felt something trickle from the cock gag. Giving a test suck for it, she found out it gave water every time she sucked. Finding she was little thirsty, S’Zira drank greedily and relaxed down again to wait another round. She remembered not putting it to random setting, though.

Few minutes later, she felt the pussy plug expand again, this time over 10 inches long, at least. She wasn’t sure, but it sure started filling her pussy now. The vibrations started again in all of the plugs, making her slowly reach into her climax again. Just as she was about to orgasm, they went silent, leaving her to the edge. Then they started again after few minutes. And stopped again before she could orgasm.

This continued for about hour, until they finally allowed her to orgasm. S’Zira felt exhausted from pulling her bonds and constantly being in near-climax state. After drinking some water, she felt the plugs expand again. The plug in her ass expanded inch or two in length and little in thickness, filling out her rectum, but not painfully. Meanwhile the plug in her pussy expanded large enough to poke her cervix; this make her starting to squirm again. After a few minutes, they started vibrating again, this time one at a time in random patterns, keeping her in state of arousal, but nowhere close enough to orgasm.

S’Zira lost track of time as the hours passed by, the plugs vibrating randomly, giving her occasional orgasm as they happened to activate on same time long enough. Pulling weakly on her bonds, she started wondering, when it stops. It surely must have been long since that two hours limit passed by.

Some time later, when the counter started ticking the last hour on, the vibrations stopped, leaving S’Zira panting hard into her cock gag. With a groan, she felt the plugs expand again after hours. “When it will end?” She thought.

Her muscles were completely loosened from the long torment of orgasms and vibrations, so she didn’t feel pain as the plug in her ass expanded into its second largest shape, easily stretching her rectum. S’Zira did feel the plug in her pussy finally invade her cervix as it expanded though, being slipped past the entrance at some point.

The plugs stopped their expansion and remained still for a few minutes. Then they started expanding again, much to S’Zira horror. Her pussy plug expanded into its final size, streching her vagina tightly around it, while its head poked the end of her cervix enough for her to feel it in the bottom of her stomach. S’Zira yelped a little in pain as the plug in her ass begun its expansion. This time she felt twinges of pain from stretching as the plug streched her rectum into its limits around the plug, like condom.

When it stopped, S’Zira was panting hard. Even a little movement with those monsters inside her felt sensitive. She screamed into her gag when they started vibrating again.

The vibration continued for the rest of time, making her orgasm had again and again, as her muscles tightened even harder around the monster plugs.

Finally, the time counter clicked into zero, shutting down the vibrations and releasing the leashes. From some time, S’Zira just laid on there chair, until she released the locks on her cuffs one by one and then the pipes from their valves. They didn’t release the pressure from plugs inside her, though S’Zira didn’t notice yet. Stumbling out of the chair, which was now damp from the juices she leaked over it during her torture, she limped blindly over to the table where she searched for the magnetic key to open the locks. Fumbling around a bit, she found the small cylinder, and moved it around the plate in front of her collar. With a click, the plate with O-ring clicked open, revealing the normal lock. Cursing into her gag for forgetting that little fact, she searched for the key, and found it after fumbling around few more minutes.

Feeling the collar finally click open, along releasing the mask, she zipped open the mask and took it off, revealing her sweaty face.

“Dammit, that was… pant… intense… pant…”

Dropping the mask onto the table, she continued fumbling around with her harness’ magnetic locks. Finally getting all the locks open, she tried to pull the harness base off, but was faeed with resistance and some pain.

“W-what the hell…?” Trying again, she found out that the plugs were still expanded; and too large to come out, thanks to the narrow bases keeping her entrances unstreched.

Sighing, S’Zira started working off her suit. Releasing her tail and stretching the suit carefully over her harness, she now sat in the cold cement floor naked, with the harness still stuck on her.

Pulling carefully, she started working out the plugs. Half hour later, she still had them stuck inside her. Sighing in frutration and exhausition, S’Zira decided to let them be for now. Re-locking the harness again, she put on her shirt and went upstairs to get some sleep. Maybe it will be easier to get out in the morning. She passed out right away when she got to bed.

Next morning, S’Zira wakes up. Yawning, she sats up, only to flinch, as she feels something large inside her rectum and vagina, up to her… cervix? Suddenly remembering the previous day, she rubs her temples, thinking a way out of this. Looking around the house, S’Zira finds that her brother hasn’t returned yet, so she goes back down to the lab.

Reaching the lab 3 again, she unlocks the harness and tries to pull it off carefull again. This time she manages to move them out, rather slowly though. 40 minutes later, she finally manages to stretch both of her holes enough to slip them out slowly. Few minutes later, she lies on the floor panting, staring the monstrosities that were inside her few moments ago. Her tailhole and vagina gaping wide open from all the stretching she experienced previous day.

Slowly getting up, S’Zira limps towards the lab door, grabbing the package finally, and is about to leave…

“Hee, it wasn’t that bad, actually… Maybe I’ll come back down here again next time…”

Grinning, she looks over the lab once more and leaves.
