Unexpected/Unwanted Surprise in a Hospital

A teenage girl with a flashlight in her hands walks through the hallway of an old hospital as she looks around the place. "Come on, I know something here has to show or prove that the doctors here were crooked and were experimenting on people's brains." She said to herself, oblivious to the thing on the floor slithering towards her. She soon entered a room that had only one window with bars and a single bed. "Well, that's very ominous."

Before she could move on, she felt something wrap very tightly around her ankle, coiling up her lower leg. "What the…?!" She looked down and saw more of what she saw around her leg coming towards her as she let out a frightful scream. “AAAIIEEEEEE!!!”

It seemed like a nice day in the city of Canterlot, and the Rainbooms were having some milkshakes at Sugarcube Corner. “C’mon Rarity, I dare you…~.” Rainbow said to Rarity, attempting to goad her on.

"And I told you for the tenth time, no I will not do something so frivolous and pointless!" Rarity replied with an annoyed tone.

"What in the hay are y'all going on about?" Applejack asked both Rainbow and Rarity.

"Rarity is just refusing to do a dare about going to that old hospital outside of town and staying the night." Rainbow explained as both Fluttershy and Pinkie Pie let out gasps of shock.

"You mean Tenta-Hospital?!" Pinkie asked in shock.

"The old and creepy hospital that did something horrible to every female that was in it?!" Fluttershy added with fear.

"Oh come on, that place is just a superstition." Twilight spoke up. "I mean, why would any hospital torture females? That would obviously be one of those old prisons and madhouses. As for the mind messing thing, I'm pretty sure it was just neurosurgeons doing their work."

"Well I heard that a few nights ago, a news reporter went in to find proof and came out like something messed with her head." Rainbow told the girls with a cryptic tone.

"I'm pretty sure she was like that before because of her editor and boss." Sunset joked. “Or maybe the stress of the job finally got to her.”

"Either way, I'm still not going into that ghastly place with so much dust and who knows what else is there." Rarity said with a huff.

"Okay, then let's bet on it." Rainbow told Rarity with a smug smile. "If you stay in that hospital the entire night and not come out until morning, I'll wear whatever you want me to wear for an entire year." This has piqued Rarity's interest.

"Really? Even the most fabulous, and in your own words 'girly', dress I could make?" Rarity questioned with a raised brow.

"Yup, but if you chicken out, you have to wear my gym clothes during school every day until summer." Rainbow added.

“What?! Please don’t tell me they’ll be dirty…” Rarity asked nervously.

"Oh yeah, I sometimes forget to wash them, and they get really stinky by the next day when I take them out of my bag." Rainbow replied, which made the other girls gag in disgust. "So, do we have a bet?"

Rarity thought for a moment and she didn't want to wear anything filthy that had not been washed for a week or so, but then again she would get the opportunity to finally put Rainbow Dash in something beautiful. She then looks towards Rainbow Dash who held out her hand before taking it as they shook on the bet. "Very well, you have a bet, darling." She told her with a smile.

"Also, don't over pack your things." Rainbow quickly told her. "You're just spending the night in an old hospital." Rarity just rolled her eyes at that remark before standing up.

"Very well. Now if you'll excuse me, I must get myself ready for the night." With that, Rarity left to prepare herself for her night in Tenta-Hospital.

"She's fucked." Pinkie said before sipping her milkshake.

"PINKIE!" The girls shouted when she said that. Little did they know however, Pinkie’s words would soon prove true, but not in the way you might think.

Soon, night fell and Rarity's car was seen parked just outside the old hospital as she was walking her way to the front entrance. "Okay Rarity, you can do this." She said to herself. "Just spend the night in an old, dirty, creepy hospital so you don't have to wear Rainbow Dash's dirty clothes, and you can finally get her into something fabulous for a whole year." She reassured herself before she pushed open the front door.

Rarity then walked into an old lobby filled with old chairs and a broken table in a corner. "Oh dear, don't let the filth get to you and remember what's at stake here." She whispered as she walked past the lobby and entered a hallway. She looked around the place as she walked down before she suddenly slipped and fell on her butt. "Oh… what did I slip on?" He questioned as she felt something wet on her hands when she touched the floor to get up.

Her pupils shrunk when she felt it before she brought her hand up and saw that it was covered in some sort of slime. There was a bit of silence for a couple of seconds before she let out a scream that filled the entire building. "Ewewewewewewewewewe!!!!" She shook her hand fiercely before running off to find something to wipe the slime off. She made her way up the stairs and to a room where she finally found some paper towels.

She quickly pulled and ripped off as much as she could before fiercely wiping the slime off of her hand. "WHY?!?! WHY DID I AGREE TO THIS?!?!" Rarity shouted dramatically before she smacked herself. "Get it together! If you run out now, you will be wearing disgusting gym clothes for the rest of the school year!" Just then, a thought came across her mind. "Where did that slime even come from?"

She then noticed a bed in the room she was in before she let out a sigh. "Okay, you can dwell on that thought later." She told herself. "For now, just rest and hopefully this will all be over soon." She then walked over to the bed, used some more paper towels to remove dust off the bed, and laid down on it. She then lets out another sigh before relaxing, closing her eyes and trying to get some sleep. Unbeknownst to her, her scream from earlier had awoken something inside the hospital as something was crawling through the halls of the hospital.

Whatever it was, it seemed to be looking for something, or someone, it got near the room where Rarity is sleeping in. It sensed her presence, her scent, and found the open door like a predator hunting down its prey. Then, something started to slither on the floor and into the room, and over to Rarity’s bed. They looked red as they're very rigid and slimy tentacles with no suction cups and made their way over to Rarity. They went up the legs of the bed before slithering on the bed. Rarity was sleeping soundly before she found something very wet and slimy, coiled around her arms and legs. She quickly woke up to find the tendrils wrapping around her as she let out a fearful scream.

"What is this?!" She screamed as she struggled to get her arms free from the tendrils before more suddenly went into the room and wrapped around her whole body. She tried to use her magic to get them off her before realizing she left her geode at home, leaving her completely defenseless as they made the bed go vertical. She struggled to free herself more before a few tendrils let out some sort of substance all over her clothing. She then saw some sort of steam coming off her own clothing before she saw her clothes being dissolved by whatever substance it was. This had made her both scared and angry as whatever it was that was attacking her just ruined her clothes before another tendril burst from under the mattress and rubbed itself against her crotch.

She then noticed another tendril with a more phallus-like tip, near her face as it looked like it was aiming towards her mouth. She closed her mouth tight as she frantically swung her head from one side to the other to not let the potential get near her mouth. Two more tendrils then went up to her mouth and each one grabbed the ends of her lips before forcefully opening her mouth. This had given an opportunity for the first tendril to finally thrust itself into her mouth. Rarity cried out with the tendril in her mouth as she felt the taste of it hit her taste buds as it tasted disgusting to her.

Tears ran down from her cheek as it ruined her mascara while she struggled to free herself from the tendrils that seemed to be groping her. She could still feel one of the tendrils rubbing itself against her panties that grew more damp by the second. Then, the tip in her mouth started to release some kind of fluid down her throat, and the other part of that tentacle outside her mouth released a strange scent in the air. Rarity gagged around the cock as she felt whatever fluid it was filling her cheeks. But then as she was inhaling the mist and tasting the liquid, all of a sudden, she felt herself relaxing, and the taste didn't seem to be at all revolting anymore. Entranced, Rarity then began eagerly drinking this delicious secretion that was being fed to her.

She then felt another pair of tendrils grab hold of her panties and slowly begin to rip it off her. This didn't seem to affect her as the liquid and the strange mist in the air was making her mind be all fuzzy as the tendril that was rubbing itself against her crotch was now rubbing against her wet cunt. She suddenly let out a moan around the tendril in her mouth, before two more opened up, with sharp pointy ends on the inside, and they suddenly stuck themselves into her breasts. She felt the two tendrils injecting something into her breasts before pulling back as both her breasts felt like they were on fire. She then let out a scream around the tendril in her mouth as she felt her breasts expanding from C cups to big E-size.

Everything around her started starting to become all fuzzy before she suddenly felt a tendril enter her cunt and begin thrusting in and out of her. This had made Rarity moan louder around the tendril in her mouth as her eyes went wide and rolled in the back of her head. Each thrust into her seemed to me stronger and faster than the last as she could barely keep herself together from this unwanted pleasure she's receiving. It wasn't long before she came, and the two tentacles that were in her released their fluid inside her. She enjoyed swallowing the squirted juices, and her nethers being filled up, before the tentacles pulled back and squirted this liquid all over her body. With the tendril now out of her, she gasped for air as she coughed up some of the liquid she was swallowing before the tentacles loosened their grip on her and her limbs fell to the bed.

Rarity laid there in euphoria for a while before the tendrils gripped her tight yet again and started to pull her towards the doorway. She saw what looked to be some sort of giant plant with a big venus flytrap-like/pod-like mouth, but with no teeth, and a large hump on its back while the tendrils came out of its mouth. The sight of it caused Rarity to snap out of her trance and let out another scream. She thought that it must be trained to eat her as she struggled to get free from the tendrils and crawl away from it. The grip on the tendrils and the slime that had covered her made it difficult for her to get away as she was getting closer to this creature.

Without her geode and magic, she tried to look for something to help defend herself from this thing before she grabbed a broom on the floor. When she was close enough to the creature, she beat it with the broom but it had no effect as the lower part of her legs suddenly entered its mouth. She struggled to get away from it yet again before it opened its mouth to let its very long tongue wrap around her and draw her closer to its mouth. She cried out as the lower part of her body entered its mouth while she used the broom to try and keep herself from going any further in. She held the broom sideways as it hit the archway of the door and she struggled to pull herself out of its mouth.

This creature seems to be very strong as it was pulling her in and Rarity held on tight to the broom. She felt her grip loosening as it dragged her deeper into its mouth before she couldn't hold on any longer and she entered the creature. From within, multiple tendrils were all around her as they covered her in slime while she was being jostled around. She can only guess that this creature was moving and could barely see where from its mouth. She struggled to keep the tentacles off of her as she smacked or pulled the tendrils away.

This has remained fruitless as this seemed to make them more excited as more emerged from the walls of the inside of the creature. Each tendril released more of their liquid onto Rarity as she felt herself becoming a little disoriented and aroused again, until the creature stopped before it let out some kind of roar. This roar however, made its mouth open wide allowing her to slip right out of the creature and into some sort of storage room.

However it seemed the creature didn't want to let her go as she still had a few tendrils wrapped around her, as well as its tongue. "Let… Let me go… you… you…" She tried to demand as it was trying to draw her back in. But she found herself at a loss for words as her mind grew more foggy. The fluids that it had drenched her in had mind-altering properties to them, and they made it more difficult for her to focus enough to crawl away and easier for it to draw her in. Rarity soon entered its mouth yet again but she held onto the outside of it while it moved up to her breasts and started circling around her nipples before she was inside the creature yet again. Tendrils with some sort of strings at the end started to rub themselves against her cunt and breasts before she slid right out of the creature yet again. As it was trying to bring her in again, Rarity struggled to look for something before she found another broom and tried to swing it at the creature yet again.

Soon her lower body entered the creature while her upper half tried to use the broom to keep the mouth open. However, it seemed she no longer had the energy or focus to do so, and she could feel the tendrils inside it starting to mess around with her lower holes. She felt two tendrils thrust themselves into her cunt while another penetrated her ass. She let out an unwanted moan before she felt its slippery tips slide around her nipples while another phallus approached her face. Rarity had no time to react, and she was too disorientated to, as the phallus entered her mouth and pumped more liquid into her gullet like before. All that slime on her skin and the liquid pumping into her was slowly weakening her mental defenses as she was slowly succumbing to lust, and submission to her master’s will.

The secretions it was pumping into her mouth was making her go relaxed and aroused like before, while the three tendrils in her lower holes thrusted more harder than before. She struggled to snap out of it as best as she could, but it was all in vain as the effects dulled her faculties, and her mind was being intoxicated and altered by the powerful feelings of lust.

Next, the inside of the pod-like mouth was filled with the same mist like earlier, which made her relax and submit even more. Rarity then felt her pussy getting more wet than before, and her breasts and clit becoming more sensitive. Her desire to be filled, to mate was all that remained. Now she was fully under its effects, and any restraint had been suppressed. She moaned in pleasure as she felt the tendrils becoming more wild inside of her.

Sensing its prey had been mentally subdued, the plant’s tentacles wrapped themselves around her arms and calves. It restrained her arms behind her back, while anchoring her legs to a kneeling position at the base of the pod-mouth. The only movement she could afford now was her hips. Then, the tendrils inside her cunt removed themselves, this caused Rarity to feel disappointed while she had been suckling the tendril in her mouth. From the very end of the pod at its base, emerged a huge phallus shape. It was bigger than any cock a human could possess, covered with bumps and ridges. At first she was both nervous and excited at the prospect of having that inside her. The plant positioned her above the phallus and lowered her onto the huge cockhead.

Rarity squealed as the immense pleasure of this inside her and began eagerly bouncing her hips up and down. The next thing she knew, the other tendrils suddenly moved in on her as some of them started to enter her asshole while a few wrapped around her breasts. This caused her to scream around the one in her mouth before it pulled out and squirted more liquid all over her face. She then let out pleasurable screams as she felt five penetrating her ass while a big huge one roughly thrusted into her cunt as she rode it. Her chest received an equally wonderful fondling, and it wasn’t long until she reached her climax, Rarity moaned and squirted her juices all over the phallus and the inside of the pod. She was rewarded for cumming by having a sweet nectar secreted into her mouth, and another fluid squirted into her crotch.

Rarity had passed out after those orgasms, so the creature released her from the pod and laid her on the floor to rest, as it too needed to regain its energy from her cum.

Rarity opened her eyes as she laid on the floor just a few feet away from the creature. She noticed that the tendrils that were wrapped around her were gone and her breasts had expanded in size before remembering what had happened. "Oh my…" She whispered as she realized this thing did the same for that news reporter. "I n-need to get out of here and warn the girls of this… thing." She half told herself, while the other half was still conflicted by the pleasure she experienced, and the effects of the fluids and juices hadn’t fully worn off. Rarity couldn't deny that she enjoyed much of that. She slowly crawled away from the creature and doesn't even care about the bet anymore. She almost made it to the door before a tentacle suddenly wrapped around her ankle. "EEK!!"

She looked back at the creature as she struggled to shake the tendril off her ankle before the large hump of the creature suddenly glowed and released some sort of fragrance in the air. The glow itself was mesmerizing while the scent in the air made her mind become fuzzier than ever, and was soon overcome by lust and desire. She suddenly started to crawl over to the creature as it opened its mouth and she crawled inside. From within the creature, Rarity let out pleasurable moans as she was letting the tendrils pleasure her by either playing with her breasts or thrusting inside of her cunt and ass.

She either kissed or licked each tendril that passed by her lips while stroking a few of them, with her hands or feet, while the ones inside her kept thrusting and sliding in and out of her holes. Rarity was once again lost in a world of pleasure and she moaned at the endless tendrils and the pleasure they were giving her. This time, she was doing this all by herself without being restrained, and for what felt like hours, she was squirted with slime, and cumming on the tendrils over and over again. Some liquid from the tendrils, and her lady honey covered the base of the inside of the plant, before she got on her elbows and knees and started to slurp up the liquid like a dog as she used her tongue to lick up all of it.

It seemed like Rarity had her mind completely gone by this creature and was enjoying every last second of it as more tendrils began penetrating and pleasuring her, and she kept releasing more juices for the plant monster.

After a while, Rarity was getting fatigued so the plant stepped in to continue extracting more fluids from her. She was restrained to the wall of back of the hump, and it continued fucking her, making her cum over and over again.

Eventually, once the creature had gotten its fill of her fluids, it released her onto the floor and left. Rarity was so exhausted that she couldn't move and fell asleep for the rest of the night. When she wakes up the next day however, part of tonight would remain with her.

The next day, Rainbow and Applejack were walking together as they were discussing something. "I'm telling you that Rarity chickened out around midnight last night and probably headed home." Rainbow bragged.

"And I'm telling ya that Apple Bloom was with her friends at Sweetie Belle's place last night for a sleepover, and they said they haven't seen her all night." Applejack told her with an eye roll.

"Oh please, they probably just said that because Rarity told them to cover for her." Rainbow argued before they reached Rarity's Boutique both hers and Flash's car park in front of it. They noticed a bit of mud on Rarity's car as a sure fire sign that she definitely drove out to the hospital.

"Well would you look at that." Applejack said before she looked at Rainbow with a brow.

"Th-That doesn't prove anything!" Rainbow told her before they could hear moaning coming from inside Rarity's Boutique. They wondered what was going on inside before they went in and their jaws hit the floor at the site they had just seen. Rarity was there, but completely naked with both Twilight and Flash on the floor. She was forcing Twilight to lick her cunt as Rarity sat on her face while she was sucking off Flash. They also noticed that Rarity's breasts have expanded.

“Rarity?! What the actual fuck are you doing!??” Rainbow asked her.

“Oh, just having some fun, like last night~!” She replied. "By the way, I won the bet!" This had made Rainbow grow worried.

"Ya mean ya stayed the whole night in that hospital?" Applejack asked as Twilight smacked Rarity's ass to try to get her off, only to make Rarity moan in pleasure.

“Yeah, we should all go back there together sometime~.” Rarity said before she went back to sucking off Flash's cock.

"J-Just to be clear, she forced us into this!" Flash explained himself and Twilight.

"Okay…" Rainbow said before shaking her head and looking at Rarity. "Bet's a bet, what kind of dress do you want me to wear?" Rarity pointed to Something in the corner of the room while she continued to suck off Flash. Rainbow and Applejack turned to where she was pointing and they were both shocked to see it was a black leather dress with the breast cups cut out, a hole in the panties around the crotch area, and a dog collar around the neck of the mannequin. "Oh fuck me…"
