"Good day class! I hope you all had a good weekend. Today we are discussing a unique topic in regards to inflation-based relationships. We have already discussed the importance of consent when it comes to dealing with somebody who has grown in some way. However, I feel that it's important to bring up the idea of inflating a partner of yours. Obviously, the same rules apply. I won't deny that there are exceptions, if you and your partner enjoy expansion-based pranks, that is a fine way to enjoy yourselves. However, there are still limits, and there's a level of respect to maintain."


Suki smiled as she drew several diagrams on the chalkboard to suit her point. Despite the artistic merit of her doodles, there were many students in the class who were instead focused on the massive wobble of her backside as she leaned into the chalkboard. The heavyset cat had thankfully learned how to use the chalkboard so that her succulent tummy didn't rub against it. But that technique simply made her rump jut out in such a pleasing manner that it was very attention-grabbing.


At the very least, it could be said that her skirt fit over her doughy cheeks. In the same way that a few sheets of cellophane plastic could fit over an entire roast pig if they were stretched far enough. But, considering her students had at times seen her skirt at a length that barely touched her butt crack, this was a generous level of modesty for Suki. When she turned back around, the tall woman's belly came into view instead, in its round, shiny glory. That would assuredly never be covered, and while her breasts were equally impressive, she was at least able to keep those in a buttoned-up shirt that only exposed a foot of cleavage.


"In my opinion, one of the most intimate methods of inflating your partner is with a kiss. To help demonstrate this, I've brought in an assistant today! One that won't be a troublemaker," she said, as her eyes narrowed in an anger-filled memory. "Gina, could you introduce yourself?" A young brunette woman stepped forward from the corner of the room and adjusted her glasses.


"Yes, hello everyone. Ah, my name is Gina. I help the school with their computer system and network, so I've known Suki for a few years now." She patted down her knee-length skirt, which hid a somewhat-chubby bottom. "She asked if I would be willing to help out with a demonstration, so she told me ahead of time what she'd do, and I agreed!"


Suki smiled and clasped her hands together, then approached Gina. She towered over Gina in every aspect, mainly height. But she outsized the woman's curves as well. Gina blushed as she felt how close Suki was to her. In any other city she may have been considered curvy, and a bit chubby as well. But next to Suki, Gina felt a lot better about eating a second toaster package of toaster pastries in the morning. Still, it was impressive that Suki had managed to look as thin as she did, considering the last time Gina met Suki, Gina had wound up getting thoroughly bonked with her belly and boobs.


"Yes, it's important to know limits ahead of time," Suki said. "There are just some certain activities that you cannot do on your own. I believe we're familiar with the classic thumb blow." Suki took one of Gina's hands and gently pulled it up to her mouth. "Where it's important to get a nice, good breath, and then blooow." She blew air right over Gina's thumb, with her pouty lips wrapped over the IT specialist's finger.


The finger quickly inflated, and then air blew through the rest of Gina's hand. Her fingers puffed up one by one like small hot dogs until her palm grew swollen as well. Then Gina let out a whimper as her boobs inflated. She'd worn a large hoodie over her clothing that day, so as her breasts grew, the zipper on the hoodie began to shift. Gina's boobs inflated from small handfuls up to modest peaches of growth. Underneath her skirt, Gina's rump swelled, and her panties began to shift to settle more comfortable in her expanded cheeks. Suki stopped after enhancing Gina's hourglass by a small amount.


"Now, of course, this is something that you can do yourself. But a puff kiss, well, you need a partner. Are you ready to demonstrate, Gina?" Gina gulped and nodded. 

"Of course! I'm ready for anything. I wouldn't have agreed to this otherwise, right? Hehe…" Suki placed her large paws on Suki's face. Suki's gorgeous visage was not marred at all by how heavy she was. If anything, she looked more beautiful with some heft in her face and a plushness to her cheeks.


"Mmm, now in my experience, a puff kiss is even better if the one initiating it has a lot of room to give a nice deep breath." She pushed her titanic belly against Gina's small pooch. "So you may grow quite big," she teased as her lips closed in on Gina's. They were so soft and plump. Gina shivered a bit as Suki's juicy suckers closed around hers, and then she felt Suki blow.


"Mmmmmmm…" Gina let it happen. The rush of warm air flowed into her body and made a tingle spread throughout. Her nipples perked up, but underneath the black hoodie, it was hard to tell. Meanwhile, everything else on her plumped up deliciously. Her opposite hand inflated until it matched Gina's right, and a firmness came to her normally-soft belly as Suki's warm breath filled her up.

"Ahhh, you see, mmf, as you blow into someone, they feel warm to the touch, and it's generally a widespread inflation as opposed to somewhere localized." Suki took another deep breath and blew once more. Gina pushed herself onto her tiptoes to keep the kiss going, as it placed her lips closer to Suki's for an easier inflation. Gina's bosom, belly, and buttocks all grew in equal proportion. The zipper on her hoodie began to slide down to expose the t-shirt underneath as her breasts stretched it out. Down below, her burgeoning tummy was enough to pull the shirt out from her skirt, and her hoodie lifted up to show off her softness.


"Mmm-hmm," Gina moved her hands onto Suki's face and gently rubbed it while a faint stiffness came to her arms. She was still able to move her arms and legs fine, but there was a rubber squeak as she pushed them forward. The sensation of them pressing her inflated breasts together was also enjoyable, as indicated by her strawberry-sized nipples throbbing for attention. She turned to the side, which let the students see the angle of her body as all 3 Bs swelled out further. Her skirt had been down at her knees beforehand, and now it was just at the lowest curves of her butt. Since she was upright, there wasn't any panty shot yet, but it was certainly on its way.


"Hahhhh." Suki broke the kiss for a moment, but Gina's face was still puckered. Her eyes were also closed, and she opened one curiously as if waiting for it to continue already. "Of course, in any scenario like this, you want to make sure your partner has time to take a moment and relish in the sensations, or, to ensure they want to continue! If at any point they think they've reached their limits, you need to cease, and comfort them. Gina, do you want to keep going?" Gina's eyes widened.


"Yes! Yes please! Ah… f-for demonstrative purposes. I've barely grown at all here, hehe…" Gina's face was now as red as Suki's suit. But either the older woman didn't notice or didn't want to bring it up. Suki smiled and took a long, deep breath. It was big enough to make her belly expand outwards even more than it already had. Gina was amazed that after her growth, she was still smaller than Suki in every regard. But the teacher seemed ready to fix that.


The next burst of air that rushed into Gina's body was so intense that her feet were lifted off of the ground for a moment. It was not enough for her to go airborne, but the sensation and pleasure just made Gina feel lighter than air before she actually reached that level of buoyancy. She gasped and let Suki push more and more right through her body. The zipper popped off of her hoodie and revealed the shirt underneath. The text on it was stretched out intensely, with 'My Brain is Trash' pulled across two breasts that were each the size of basketballs. 


Her belly was slightly bigger, with her belly button deep enough that someone could stick a plum inside with a fair bit of spare room. It was taut, and as tended to happen when someone was inflated enough, there was a shine to her belly. Gina's arms and legs also plumped up, making it somewhat harder to move around. Not that she wanted to move away from Suki at this point. Gina simply basked in the bliss as her ass grew to the point that her skirt no longer contained it. The panties she wore, emblazoned with little Pokeballs on it, were slightly swallowed up by her cheeks as they bubbled out happily. Her hips pushed outwards until they had moved past her shoulders in width.


"Mmmmnnnnghghh," Gina's body felt so warm and pleased by what was happening. Even the stares from this educational display weren't deterring her. In fact, Gina may have been happier to accept this offer once she found out people would have been watching her. Everyone had their kinks. Gina eventually was on her tiptoes for more than just being closer to Suki. Soon her body reached a state where she was almost light enough to need some anchor to the ground. If she lifted her feet off of the floor, she would have hovered for a brief second before falling down.


Gina's body felt so wonderful that she didn't want it to stop. Her body tingled like she was in the most amazing bubble bath. Her head felt fizzy as if a gallon of soda had been poured into her noggin, and the carbonation was tickling her brain. She felt her belly finally eclipse Suki's in size as it swelled out to such a massive belly that the bottom half of her shirt was scrunched up between her tummy and her boobs. The second half of the text that said "And I Live on the Internet" was squirreled away while the top half was so stretched that each word had tripled in width.


"Hahhhh, thank you," Gina whispered as Suki finally broke the kiss. Gina remained on her tiptoes. Her shoes felt somewhat tight on her feet now, and her calves had fattened up where each one was as thick as her chunky thighs used to be. She pulled down on her skirt from the sides, but it wasn't doing much. Thankfully she faced everyone from the front, so they couldn't see how her skirt only covered half of her inflated ass and her bouncing butt cheeks were heavily exposed, even with her panties being super elastic.


"Mmm. Very nice, Gina. Thank you. Here's an interesting lesson on buoyancy, if you'll allow me to demonstrate?" Suki asked. Gina nodded quickly, and Suki teasingly grabbed Gina's hand. She pulled, and Gina was lifted off of the ground instantly with very little force. Then Suki let go and Gina bounced back to the floor after a few seconds. "If you fill someone up just right, then they're at a very fun stage where they won't be floating off, but they'll still be very pliable and fun to play with. Gina, do you mind explaining the experience to everyone?"


"Oh, it's wonderful," Gina said through a shuddered, hot breath. "Every part of your body just feels like you're in the most expensive, lavish spa possible. You can still walk a bit," she said, and demonstrated as much with a bit of a waddle. Her fat thighs rubbed together happily as she did a quick spin. "And, mmf, it's almost… addictive? Though that may just be enjoyment, haha. But it's very comforting. Your body's a pillow wrapped in blankets just from someone kissing you."


"Thank you Gina! I think that was a good demonstration of what a puff kiss was. I think for your benefit, I'll let you go while you can still get home." Gina heard those words and they seemed to just go through her head. It didn't make sense to her. Surely they needed a proper demonstration, right? She'd heard of what had happened in Suki's class before. This was all she was getting.


"Ahhh, of, mm, of course. Ah, just… allow me to show my appreciation." Gina jumped up slightly and then grabbed Suki's face. She took hold of those puffed-up cheeks, and then sucked as hard as she could. Suki looked surprised as Gina inflated fast, with her feet leaving the ground rapidly and sticking out firmly beneath her. Gina had to do her best to keep her hands on Suki's face. But as her body rounded out with a supreme amount of air, it became harder to keep a grip on the plump catwoman. She squirmed and winced as she felt her arms tighten up and her fingers swelled and stiffened.


"Mmmnnghgh!" Gina whimpered as she was reluctant to let go of Suki. But eventually her arms were unusable and flung out to her sides like a scarecrow. To Gina's relief, though, Sukis held onto Gina and kept the kiss going. Now it was Gina's time to find out that Suki had been holding back in the previous kisses. The rush of air she got wasn't just bolder, it was hotter. She felt her belly inflate so fast that she swore it grew more in just a few seconds than it had from all the previous kisses put together. 


"Mmm~" Suki coyly raised an eyebrow at Gina as the brunette grew to much larger sizes. Her skirt flipped up to show how pitiful it was in comparison to the mammoth display of her ass as it rose to the ceiling. She was light enough to float, and it seemed her bottom-heavy nature gave her a predilection to float butt-up. Each cheek was as big as a beach ball, and the Pokeballs on her panties had been stretched out so much that they were as round as discs instead of cute, tiny icons. 


Gina's shirt had already been bunched up around her huge boobs, with her stiff nipples looking like air plugs as they grew as fat as energy drink cans. Her butt had outsized her boobs, which had somewhat stalled in their growth, but not until they'd torn her shirt somewhat. There were some rips in the cleavage, and her arms had grown so puffy that the sleeves popped off entirely. But while Gina always considered herself pear-shaped with a belly, her belly received the bulk of Suki's growth.


Even as Gina's backside reached the ceiling and she felt the heat of fluorescent lights on her panty-clad skirt, her belly nearly touched the floor. The fat, wide dome was bigger than a yoga ball. Tucked away slightly was her belly button, which had popped out after a few seconds of this decadence, and turned into a solid nub the size of a cantaloupe. Gina's eyes closed almost all the way. She was too basked in pleasure to understand her surroundings or just how big she was. Gina didn't even care that her embarrassing lower back tattoo was visible, showcasing an upside-down symbol from her favorite video game. The three golden triangles pointed right to her butt. Suki giggled as she finally broke the kiss. But she held onto Gina so her tush didn't press too hard into the ceiling.


"Ahhhh. There we go. What Gina helpfully demonstrated for me just then was that with knowledge of your partner and an understanding of what they need, you may be encouraged to go further than you expected initially. Remember how important communication is. Anything else to add, Gina?" Gina slowly shook her head, and breathed heavily. Suki snickered ever-so-slightly, and leaned forward once more.


"And if you're skilled enough, you can help to reach an equilibrium by pulling some air back into yourself. As I shall now show you." Gina shivered as Suki pulled air out of her by sucking on her lips this time around. While inflation felt hot, deflation was cooler. It was like going from a comfy, snuggled-up bed to getting a brisk chill from the autumn air, though it was enjoyable as well. Gina slowly lost enough of her air to lower back down to the ground again, with her curves shrinking to match. 


It was probably to Gina's benefit that Suki took air out of her. Not only did it mean she'd be able to get on with her day more or less, but it also meant that Suki inflated as well. That glorious brown belly of hers fattened up extravagantly fast, and the rest of her soon followed. As huge as Suki was on a regular basis it was still a joy to see her grow and expand. The tight fabric of her clothing was still made to stretch.


Suki let go of Gina's body with one hand, and the other carefully undid a button on her shirt to allow for more growth. There was a faint trace of her dark areolae that was shown from Gina's point of view, until she was lowered back to the ground again and she was able to waddle on her feet. Suki stretched as air filled her bum and plumped it up to the point that her panty line was extremely prominent. Her leggings stretched out as her thighs and calves thickened, but Suki's arms stayed more or less the same. She took just enough for Gina to come back to a resting state where her skirt hung over and covered about half of her backside.


"There you have it, everyone! The benefits and demonstration of a puff kiss. Now, there are other ways you can puff kiss somebody. In more sensitive, personal, private areas, growth may be more intense and the feelings of it would be heightened as well. But I think this is the limit of what I can reasonably share in a classroom setting," Suki stated. The large woman then took the hand that was on Gina's shoulder and leaned in with it, so she could whisper into the nerdy girl's ear. "Of course, I'm more than willing to give a private demonstration outside of the classroom, nyah."


Those words made Gina's body heat up so much that she puffed up another inch all around, and Suki smiled. 


"Again, thank you for your assistance today, Gina. I'll let you get back to figuring out algorithms and blockchain or whatever it is you're busy with."


"Ah, yes, right. I'll go do that then," Gina said. "Have a good class, everyone!" Gina bowed down as gracefully as she could and then wobbled out of the classroom. Once she was out of sight, she grabbed her phone and texted her online roleplaying group to say that she'd be busy that night and would be playing an entirely different game.
