For Science...?

Having rich friends, or at least friends with rich parents, can have its perks. Jacob knew this all too well. Instead of living in a campus dorm and paying out the nose to do so, he lived on the edge of campus in a loft/rock wall gym that his friend Lucas' parents had converted an old warehouse into for them and their friend Sam, who also lived there with them. The three friends were avid rock climbing enthusiasts, and they loved their home. Lucas' parents helped with some of the bills, but for the most part their primary source of income was giving rock climbing lessons and renting out their rock wall area for birthday parties, or people looking for a quiet place to get away and/or practice.

Jacob knew how well he had it, and he knew it all too well. He had more than enough money saved up to use on his college tuition and textbooks, seeing how he didn't have to pay rent. And on top of the prospect of getting through college debt free, he also had a smart and beautiful girlfriend named Kaylee, who he would lovingly refer to as his "black beauty" from time to time. Hell, Kaylee alone was reason enough to think that things were going in his favor. He hadn't dated a black girl before he met Kaylee, but really, she was whiter than some of the white girls he knew. 

The product of two fans of Shakespeare who met at a Shakespeare festival in Ashland Oregon, Kaylee had been given an appreciation of literature and the arts as a young girl, and had developed a passion for science which her adopted grandparents (from her father's side of the family) had encouraged as much as they could. This passion bordered on obsession at times, which Jacob knew all too well. He hadn't seen Kaylee much lately since her current project had been taking up all of her free time. But since it was finally Spring break, he knew they were going to finally get some quality time together. Especially since Kaylee and her friend/lab assistant, Lilly, were coming over to test their latest project. 

Jacob wasn't quite sure what this project of theirs was, all he knew was that Kaylee and Lilly got funding from a local business that was going to produce whatever it was that the two had been working on for months now. Apart from that, Jacob only knew that Kaylee had said that she and Lilly needed someplace that was indoors, large, and away from prying eyes so they could conduct their tests in private. So it was only natural that Kaylee had come to Jacob to see if she and Lilly could use his place to do their tests, since Lucas and Sam were partying with a few other friends down in Mexico for Spring Break. Who was Jacob to say no? He was alone with the loft to himself and anyone else he felt like having over, which in this case was his girlfriend and Lilly. Besides, after those two were done with their testing, he and Kaylee would have the place to themselves for the rest of Spring Break, and there was no way in hell he was going to miss an opportunity like this to have several DAYS alone with his girlfriend and no roommates around to ruin things for them. And that night was going to be a special night anyway. Could it possibly get any better?

It was getting around two in the afternoon, and the girls hadn't shown up yet. To be honest, Jacob was a little relieved. This had given him the time to get everything cleaned and tidy for when Kaylee would be there, and also had given him the time to get everything ready for that night. A bottle of wine, the fixings for a home cooked meal that wasn't Ramen or Macaroni & Cheese based, a movie they had been meaning to see, and a fresh box of condoms. Oh yeah. And since everything was ready, Jacob decided to do some climbing in order to pass the time before Kaylee arrived.

The building consisted of two parts; the main part was the rock wall gym, which is what the front door to the building opened up into. The living area, which consisted of three different floors, could be accessed by taking a hard left after entering the gym, and walking through two sets of doors. The rock wall area itself was large, but not huge; roughly 60ft by 40ft. The gym consisted of three main rock walls, and a sort of rock wall "island" (a 20ft long rock wall) that was 20ft away from the main entrance. The island created a sort of 40x40 rock wall climbing "pocket" on the far side of the gym. Suspended roughly 40 ft off the floor in the dead center of this area is a cargo net, in case anyone should accidentally fall off the nearly 75 ft high rock walls… but really it was there because it looked cool at the time.  It was the rock wall island in particular that Jacob had decided to climb, as he could climb the side of the wall facing the entrance and make sure that the girls saw him when they arrived. But he wasn't in any hurry to get to the top of the rock wall, as his mind was preoccupied with thinking about Kaylee. 

They had first met on a blind date that mutual friends of theirs had set up. Jacob at that time was relatively fresh off a failed relationship with a woman who had been into BDSM; just one of the many women he had dated or had been in a relationship with who had had some kind of sexual kink. This one in particular had been very keen on dominating Jacob. And while he found it kind of hot in the bedroom, he hadn't really appreciated it when she had been overtly dominant in their everyday lives. Kaylee on the other hand had been single for a few years at that time, the reasons for which Jacob only found out later.

Long story short, their first date was a success, and they had hit it off. Although they hadn't had a lot in common, something between them just clicked. Perhaps it was a combination of their personalities and their past love lives, but who really knows. What mattered was that it wasn't very long before they were officially a happy couple. And a few months after that, they became a happy albeit kinky couple. The reason for this was that Kaylee had felt confident enough to tell Jacob about her own little fetish, as he had told her about his past kinky relationships, and his general willingness to try out new things.  This revelation had just caused Jacob to laugh at his peculiar luck for attracting women with kinks, which he made sure to tell Kayla (he didn't want her to think that he had been laughing at her). 

Thus their nerdy/kinky romance began. For two years they had been together; two years to the day, actually. That night was their two year anniversary, and both had promised the other that they were going to make the night especially memorable. Jacob had figured that Kaylee meant she was going to be bringing along some of her gear for their alone time, and would alone require her to bring two duffle bags instead of just one for her clothes and stuff. Which is why Jacob was more than a little confused once the girls arrived.

"I still don't understand why you didn't opt to wear it" said the blond girl with a ponytail, walking through the entrance with a crate of some kind. She wore a white t-shirt with "G33K" printed across the front, and a pair of worn jeans. 

"Lilly, we've gone over this. It would have only been a hindrance, and you know that" replied the chocolate skinned girl behind her, her short black hair fanned out at the base of her head, and would bob a little as she walked. She had a green duffle bag slung over her right shoulder, and rolled up blue tarp in the crook of her left arm.

By this time, Jacob had reached the top of the wall and was sitting on top, his bare legs hanging off the side of the wall as he waited for the girls to arrive. "Hey honey" shouted Jacob, "do you need me to grab anything else from the car?"

"Thanks babe, but this is all we brought with us" replied Kaylee, dropping the duffle bag off near the door to housing section.

"Really? I was expecting you to have at least a second duffle bag with you, and maybe some expensive looking scientific doohickeys."

"Yeah, sorry hun, but this is it. Lilly has everything we need to conduct our tests in the crate she's carrying, and I only brought one duffle bag this time. Oh, and I don't think I'll be needing to bring the second one again after today." 

"What does that mean?" thought Jacob, his face a mask of confusion as he did.

"Don't worry about it Jacob, it'll all make sense soon enough."

Lilly just looked over at Kaylee and arched her right eyebrow; one of her inquisitive looks. Kaylee just rolled her eyes and waved her hand at Lilly as a way of saying "just forget it." The girls then made their way over to the little secluded area that the rock walls created; setting down the crate and rolling out the tarp over the blue mats. This really didn't shed any more light on what Kaylee and Lilly were doing, as Jacob still wasn't sure what the hell was exactly going on. He had some ideas, but just about everything that came to mind was either outside the realm of possibility or practically fantasy. But whatever was going on, he was sure that he was going to find out soon.

As Lilly and Kaylee got everything ready down below, Jacob stayed on his perch high above them. He had learned rather quickly just to stay out of the way and let Kaylee do her thing when it came to the scientific stuff. That, and not to touch anything. But as he waited for them get ready, he took into account Kaylee's strange choice for clothes today. Normally she would wear jeans, a t-shirt, and one of her cute little vests over the shirt. But today, she was wearing an old "Oregon County Fair" t-shirt from the 90's that she had never cared to wear, and a pair of grey sweatpants. And she was either going without her glasses today, or she had contacts in; the latter being something that she hated to do, as she didn't like putting things in her eyes. God, he wished he could clearly hear what they were saying.

"Alright Lilly, is everything ready?" asked Kaylee, her short black hair bobbing slightly as she positioned herself in the middle of the new blue tarp.

"Umm… yep, everything's ready. Which vile do you want to do first?"

"Let's just stick with the regular batch for now and save the more experimental batch for another time. Besides, I'm not even sure if we got it quite right, so let's just stick with what we're pretty sure we know will work."

"I dunno Kaylee, I think both will work just fine."

"Lilly, could you just hand me the vial I asked for so we can get started?"

The blond just playfully rolled her eyes at this, pulled out one of the vials from the crate she was bent over, and then gave it to Kaylee before hauling the crate out of the way. 

Kaylee was nervous, and it showed. So much worked had gone into this, and she couldn't help but wonder if they had done everything correctly. Any number of things could go wrong, and she was putting her own life on the line due to her being the only willing human test subject at the time. If something were to go wrong and Jacob saw her… no, she couldn't think about such things, they had done EVERYTHING correctly. It was the newer experimental batch they had created that she should be worried about, not the original formula that they had perfected in the lab.  Putting everything else out of her mind, Kaylee carefully uncorked the vial, and held it up to her lips.

"For science?" Kaylee said/asked, not knowing for sure herself.

"I thought it was more for money and personal gain. But sure, for science" replied Lilly facetiously.

"Alright then. Here goes nothing" said Kaylee before looking up at Jacob and yelling "Wish me luck!" And then Kaylee quickly downed the vial's contents before tossing it back to Lilly.

Jacob didn't have the best of advantage spots, as the cargo net obscured his vision somewhat. But what he saw nearly made his jaw drop. In under seven seconds, his girlfriend went from having a relatively trim stomach to looking like she was at term with a baby. As her stomach continued to swell, her breasts started grow in size as well, closely followed by her but and thighs. All Jacob could hear was moaning from Kaylee down below as she rubbed her swelling belly and breasts, which intensified once Lilly came over and started poking and rubbing his girlfriend. Fuck, he had to get down there.

Jacob quickly maneuvered himself back onto the wall he climbed up; the opposite side of the wall that Kaylee was on now. Making sure the rope was secured in his carabiner, he rappelled down the side of the rock wall, his mind racing as he went. His girlfriend was blowing up like a balloon! And not in the sexual role play way, or one of her fully inflatable suits; ACTUALLY inflating! His mind raced even faster as he descended as his ears were suddenly privy to the sound of ripping fabric and more moans of ecstasy. Soon as his feet felt blue safety mats under them, Jacob unclipped the rope and tore off his safety helmet before he dashed around the side of the rock wall. What he saw damn near floored him.

Where once his girlfriend stood, there was now stood what looked like a 6ft brown ball. Except this ball wasn't a ball. It was Kaylee. Her midsection had absorbed just about every indication that she was a human, and caused her clothes to shred. Her breasts had essentially become domes with thumb sized nipples on her turgid form. Her arms and legs were gone, sans her little hands and feet. And finally there was her head which rested on her swollen form, her neck practically non-existent.

Everything made sense to Jacob now: the subtle little hints Kaylee had been giving him over the last week, the lack of a second duffle bag for her inflatable suit, the project she and Lilly had been working on; everything. And as the initial shock of seeing Kaylee inflated started to fade, Jacob slowly walked up to Kaylee. A mixture of lust and joy plastered Kaylee's face and her little hands started to flap against her inflated sides as Jacob walked up to her, carefully placing his hands on here inflated form. The sensation that greeted his touch was something between touching a yoga ball and a balloon. He had never felt something like this before, yet he had touched his girlfriend numerous times before now. Jacob switched his attention from rubbing his swollen girlfriends form to looking into her brown eyes.

"I did it Jacob, I finally did it. I finally discovered a way to actually turn myself into a human balloon" said Kaylee, her voice was quiet so Lilly wouldn't hear.

"Is… is it permanent?" said Jacob hesitantly, almost as if saying it out loud might jinx something.

"No, it isn't. Or… at least it shouldn't be. But I wish it was, Jacob, I really do. I wish I could always stay like this; stay as a big balloon girl forever. I-I wish I could be YOUR big balloon girl forever."

"I don't doubt that for an instance, Kaylee. But I bet you'd want to be back to normal sooner or later. Your love for science is too strong just to be given up for permanently living out your sexual fantasy. Besides, you'd start to miss cuddling" said Jacob, now recovered from the initial shock of seeing his girlfriend inflated. (When you've role played with someone who typically wears an inflatable suit that matches their flesh tone for as long as he had, the initial shock/novelty of actually seeing them inflated wears off faster than for other people.)

"J-Jacob I-"

"Ahem!" interrupted Lilly, looking a little flustered. "Kaylee, didn't you say that you had some other tests you wanted to do if the formula was successful?"
"O-Oh! That's right, there was something I was wanting to… test. Um, Lilly? I'm going to have Jacob roll me off the tarp here, and then I want you to drag it out of this little cove we're in" instructed Kaylee, doing her best to bend what was left of her neck around so Lilly could hear her better.

"Alright Jacob, can you roll your balloon girlfriend out of the way so we can have some fun?" asked Kaylee playfully.

"Sure honey, but I'm going to get some time alone today to play with my balloon, right?"

"Oh god I hope so" breathed Kaylee, her eyes briefly glazing over.

"Uh, GUYS. I can't move the tarp with both of you still on it" said Lilly impatiently.

"Sorry" replied Jacob before pushing Kaylee onto her back, who let out a brief squeal as she fell backwards. Not checking to see if she was alright (he knew she was, and that she was enjoying it), Jacob walked around to Kaylee's side and proceeded to push her inflated form out of the way. He pushed her all the way to the other side of the little area, making sure to stop her before she hit the rock wall. Laying on her right side with the front of her facing the wall, Jacob walked around to the front of Kaylee as Lilly dragged the tarp out of the rock wall cove. He wanted to do something real quick.

"That was fun" smiled Kaylee as Jacob reached her front.

"Oh, well then you'll love this." And without any kind of warning, Jacob dragged his tongue across Kaylee's left nipple.

Kaylee gasped at the sudden rush of pleasure, which Jacob took as a sign to continue. As Lilly dragged the tarp out of the cove, Jacob used the sound of the tarp dragging across the blue mats as cover so Lilly didn't hear what he and Kaylee were doing. He continued to play with her nipple with his tongue, while occasionally sucking on it. Kaylee had to bite down on her lip to keep herself from moaning out loud. She wanted to lose herself in the pleasure so badly. But then Jacob stopped playing with her nipple; Lilly had finished moving the tarp.  Thinking quickly, Jacob used his arm to wipe his saliva off Kaylee breast, as he knew Kaylee well enough to have an idea of what she was wanting to do next.

"Alright Kaylee, tarp's out of the way. So what's next test?"

Taking a couple seconds to compose herself, Kaylee replied. "Lilly, I want you to wait on the far side of the room over there. When you're ready I'm going to have Jacob roll me over to you, and then I want you to roll me back."

"How is rolling you back and forth scientific???"

"Lilly, if you haven't noticed, I have been literally turned into a HUMAN BALLOON. To my knowledge this has never happened to anyone else before!"

"You're NAKED!" retorted Lilly. "And it's exactly why I wanted you to wear some kind of latex suit in the first place!"

"Look after this you can go do whatever the hell you want, but for now just be ready to catch-" but Jacob didn't let her finish before he started rolling Kaylee to get her going fast enough before pushing her towards Lilly. 

"WOAH!" exclaimed Kaylee as the world around her rapidly spun as she went rolling towards Lilly. However, Lilly wasn't entirely prepared for Kaylee.

Lilly had been directly up against the rock wall behind her when Kaylee went rolling in her direction, and had only hand her hands up when Kaylee went rolling right into her. The impact caused both girls to let out an "oof", and caused Kaylee to bounce back a little before rolling slightly.  After a couple of tense seconds, Lilly had regained her composure. And without saying anything, Lilly went up to Kaylee and sent her back to Jacob.

For about two long minutes, Kaylee was sent back and forth between Jacob and Lilly, who was finally starting to enjoy herself. But Kaylee had Jacob stop her and not send her back to Lilly, as she was way too dizzy to keep doing it. Once her head stopped spinning, Kaylee told Jacob to tell Lilly that she could go home now, which Jacob did immediately. Because Jacob had noticed that his girlfriend's lips were moist; both pairs actually. 

Not checking to see if Lilly had left, Jacob knelt down onto one knee so he could be at head level with Kaylee, who was in much the same position as she was before he had sent her rolling into Lilly. At this point, Kaylee was clearly horny; labored breathing, glazed over eyes, etc. Jacob went in to kiss her on the lips, but before he could, Kaylee had tried to force herself on him… unsuccessfully. When you have little to no neck to stretch out to meet your lover's lips, and no arms to wrap around them to pull them in to kiss… well then you're not going to have much success. All Kaylee ended up doing was moving her head a little while puckering her lips, causing her hands to flap uselessly on her sides, and making Jacob laugh. He didn't give Kaylee much time to pout, as he went in kiss his ballooned girlfriend on the lips. They held the kiss for a good seven seconds before breaking and then kissed again, and again, and again. Their kissing became slowly more intense until they were making out with each other; Jacob with his left hand behind Kaylee's head so she didn't move. As they made out, Jacob used his right hand to undo the climbing harness he still had on. He knew what was coming next. Breaking off the kiss, the couple came up for air; panting as they did.

"Happy anniversary" said Jacob, resting his forehead on Kaylee's.

"Happy anniversary" replied Kaylee, smiling as she did.

"Jacob?"

"Yeah baby?"

"I… I was serious when I said I wanted to be with you forever."

"You said you wanted to be my big balloon girl forever."

"Well yes, but, I want to be with YOU forever. It doesn't matter what state I'm in… but I'd prefer being inflated at least some of the time."

"Kaylee… let's talk about long term commitment when we're not both horny. But right now, I know I just want you more than anything else, and that I love you."

"I love you too."

And with that, the make out session recommenced. Not too long after that, Jacob's kisses migrated from Kaylee's lips, down her chest area, and then lower, all the while slowly tipping Kaylee more and more onto her back. But any thought he had had about going further than just kissing went out the window after what happened next.

"LILLY?!" exclaimed Kaylee.

As fate would have it, it appeared as though Lilly had never left. In fact, she had been there the entire time, watching Jacob and Kaylee getting hot and heavy, while getting hot herself. Lilly had become fascinated with Kaylee's current state, and how she might herself join Kaylee. By the time Kaylee had finally noticed her standing there with her pants off, Lilly had already obtained one of the vials of the untested experimental batch of formula. And by the time Jacob had moved enough to see for himself that Lilly was in fact still there, she had already ripped the cork off the vial with her teeth, spat it out, and downed half of the vial's contents.

"Oh shit" said the couple in unison.

Time had seemed to suddenly slow down for Jacob as Lilly's midsection suddenly began to rapidly inflate, followed by the rest of her body. Thinking on his feet, Jacob quickly got in position and proceeded to roll Kaylee out of the potential blast area, not wanting to risk his swollen lover's life should things go wrong. And had he been watching Lilly instead of getting Kaylee out of there, he would have seen Lilly's spherical midsection quickly expand outwards and absorbed her slightly swollen arms and legs. In under ten seconds, Lilly had reached Kaylee's size and was surpassing it. 

It hadn't taken long for Jacob to get Kaylee on the opposite side of the rock climbing wall, and then cover her ears for the bang… which never came. The only thing they could hear was moaning coming from where Lilly was. So to be safe, Jacob alone had gone to see what Lilly's condition was, while leaving Kaylee behind. But Jacob didn't find Lilly laying on the floor. Jacob found Lilly floating 30ft up in the air, the cargo net stopping her ascent while caressing her swollen form. And swollen it was. Thankfully for Lilly, her rapid expansion stopped once she reached ten feet in diameter. However, her face had swollen up some, hindering her ability to speak. The only thing left of her breasts were her areolas and nipples. And both her hands and feet had been partially pulled into divots in her sides.

"Are you okay Lilly?" asked Jacob.

"Mmmhmmmm" replied Lilly, who even through swollen cheeks you could tell was in a state of bliss.

"What's happening? Is Lilly alright?" asked Kaylee.

"Oh yeah she's fine" replied Jacob. "I'm actually pretty sure she's just going to hang around for a while and give you and me some well deserved alone time. Isn't that right Lilly?"

"Mmmph" was all Lilly could muster.

"I'm just going to take that as a 'yes'" said Jacob before running to close the drapes for any unobscured window in the main area that allowed viewing from outside.

"Now" said Jacob to Kaylee after completing his task. "Where were we?"
