Chapter 4: Sapphic Love
With the other Fireside Girls off earning their various patches in different parts of town, Isabella and Holly were now alone in the cabin. It seemed as good a place as any to earn their Sapphic Love patches. But location was far from the only decision they needed to make.
“Soooo,” Holly said as she finished pumping up an inflatable mattress, “how do we want to do this? I mean, should we dress up in sexy outfits, or maybe just lingerie? And do we use sex toys or stick to, you know, manual control?”
“Well, I’ve got to admit,” Isabella replied as she handed Holly one end of a flannel fitted sheet so they could put it on the mattress, “I haven’t exactly thought this through. I mean, I really want to earn this patch—and every patch—but I didn’t really consider that I’m not that into girls. I mean, no offense, you’re super cute, but after having all my sexual dreams come true with Phineas yesterday, it’s kind of hard to get excited about doing it with a girl. Maybe an older girl, but…I don’t know.”
As the girls pulled the sheet down over the mattress, Holly replied, “Yeah, I hear you. I guess I didn’t think this through either. Don’t get me wrong, you’re totally adorable, but…yeah.”
***
Meanwhile, in the penthouse apartment at Doofenshmirtz Evil Incorporated, Dr. Doofenshmirtz was walking up to where Perry hung by his webbed feet from a simple rope snare.
“Ah, Perry the Platypus,” said Doofenshmirtz. “Sorry I couldn’t get more creative with your trap today. My latest Inator has required a lot of tweaking, and it’s just eating up my whole day. Heck, I had a frozen waffle with ketchup for lunch because I didn’t have time to go to the deli, never mind the grocery store. Although,” he mused, “I suppose I could have spared a minute to toast the waffle, instead of eating it frozen…”
Perry felt a little foolish to have been caught in such a basic trap—especially by a man who would willingly eat a still-frozen waffle with ketchup. But the rope was the exact same color as the carpet, so maybe he wasn’t a complete idiot for not having spotted it.
“So if you don’t mind, Perry the Platypus,” Doofenshmirtz continued, “I’m just going to give you the abridged version of my evil scheme today. Because I don’t have time to bridge it for you, or whatever the opposite of abridging is.
“So here’s the dealio: In a few minutes, my brother Roger is going to give a speech to the youth of Danville about volunteerism, or activism…one of those isms. He thinks young people find him relatable because he has good posture, good looks, all of his hair, and all that other stuff that wasn’t at my end of the Doofenshmirtz gene pool.
“So, behold!” Doofenshmirtz cried, putting a hand on Perry’s shoulder and rotating him so he could see—albeit upside down—the large, ray-gun-like machine that was pointing out of one of the penthouse’s windows. “The Age-inator!”
The mad scientist walked over to the machine as he continued, “Now, you’re probably thinking that building an Age-inator shouldn’t be that hard, because you can age yourself pretty quickly just with loud music, extreme sports, and energy drinks. But I couldn’t build a machine that just straight-up ages people, because let’s face it: Even when he’s eighty, Roger is probably going to be in, well, better shape than I’m in at my current age.
“So I designed this baby to really crank up the effects of the aging process. Roger won’t just be an old man—he’ll be a withered, broken-down old man. Let’s see the youth of the Tri-State Area relate to him then.
“Of course, I’ve got to make sure that the targeting system is set just right. If I miss, the beam could bounce off of something, maybe a lot of somethings, and end up going who knows where. It could hit a child and turn them into a buff grownup. Or it could hit two children, which would dilute the effect and probably just turn them into really mature teenagers or something. But the odds against that are astronomical. Like, the odds are probably better that I’ll suddenly turn to the side of good and invent time travel to benefit all mankind. That kind of astronomical.” He turned towards Perry as he continued, “Anyway, time to- Hey!”
While Doofenshmirtz had been monologuing, Perry had managed to start himself swinging back and forth from his rope snare. The moment the lab-coated man turned in Perry’s direction, Perry kicked him in the face with both webbed feet, sending Doofenshmirtz staggering back into his machine. His elbow hit the Fire button.
A green beam shot from the machine and bounced off the glass of a nearby skyscraper and then the side of a silvery blimp hovering over the football game at Danville Stadium. The reflected beam shot through the open bathroom window of a third-floor apartment, bounced off the mirror, and then zoomed several blocks through the air above the street before striking a shiny, jagged piece of public art downtown. Having been reflected at an extreme angle, the beam lanced into the sky, bounced off the satellite that happened to be transmitting the broadcast of the football game, then raced back down to Earth like a bolt of green lightning.
Suddenly, from out of nowhere, a beam of green light lanced through the window of the Fireside Girls’ cabin and enveloped Isabella and Holly in a brilliant green aura for just a moment. Then the two girls’ eyes went wide as each watched the other grow a foot taller.
But what happened next was even more astonishing: Isabella and Holly’s chests expanded dramatically, until each girl had breasts the size of soccer balls. Their orange uniform tops, being made from a recently declassified material that was both extremely strong and highly elastic, had effectively become belly shirts when the girls grew taller, and now they tightened around the girls’ chests until they looked like tube tops. The tight fit of the tops, combined with the girls’ lack of bras, made every detail plain to see—including the girls’ newly enlarged, protruding nipples.
As that remarkable change occurred, another was taking place lower on Isabella and Holly’s bodies: Their hips widened, and their asses grew from small and flat to big and round. Thanks to their elastic waistbands, the girls’ uniform skirts still more or less fit at the waist, but now they were so short relative to the girls’ new bodies that the skirts didn’t even quite cover the bottom curves of the girls’ newly shapely asses. What was more, the girls’ sudden growth had stretched their durable white uniform panties until they were little more than thongs.
“Wow,” Isabella said, gawking at Holly’s curvaceous teenage body. “You look…”
“…hot,” Holly finished.
Suddenly inflamed with lust, the girls embraced and began making out like mad. They were not yet used to their new bodies, so they stumbled around the cabin as they kissed open-mouthed. The two girls’ big breasts were pressed together even as they strained against the girls’ now hopelessly ill-fitting tops, which were so tight that even through the two layers of fabric, Isabella could feel Holly’s hard, thick nipples against her own.
Suddenly, Isabella couldn’t stand the thought of her new, big, round tits being concealed by clothing for even a moment longer. She grabbed the bottom of her orange uniform top and peeled it off, causing her huge breasts to bounce free. She threw the top into a corner of the room and looked down at her chest with huge eyes and a disbelieving grin.
“Whoa! Look at these!” Isabella shouted.
Whereas Isabella was looking at her newly endowed chest with amazement, Holly was looking at it with burning hunger.
With a feral rasp, Holly replied, “I’m not just gonna look.”
Suddenly, Holly’s hands were all over Isabella’s massive breasts—feeling, squeezing, and fondling them, then seizing the girl’s nipples between her eager fingers and pinching, rolling, and tugging them with abandon.
“Oh, wow,” Holly breathed. “They’re so big, and I like them so much…”
Isabella seized Holly and kissed her again; this time, both of Isabella’s hands went down Holly’s back, over her big, curvy ass, and up under her skirt to squeeze and maul Holly’s mostly bare asscheeks. It wasn’t long before Isabella’s fingers found their way beneath the narrow white triangle that had once been the back of Holly’s panties and started fingering the girl’s pussy, making Holly break off their kiss and gasp.
“More,” Holly moaned, squirming against Isabella’s hand. “Do it more.”
“Take off your top first,” Isabella panted in reply. “I wanna see your titties!”
Holly pulled her top up and off, setting free a pair of breasts that were every bit as huge and impossibly buoyant as Isabella’s. Isabella couldn’t help herself; practically the moment they came into view, she dropped her head, took one of Holly’s thick, chocolate-colored nipples into her mouth, and sucked it ardently even as she kept fingering Holly’s pussy inside her panties.
“Oh God!” Holly cried.
Locked in a passionate embrace, the kissing, fondling girls teetered and stumbled as they tried to make their way to the inflatable mattress without unlocking their lips for even a moment. They managed to make it to the foot of the mattress, and Holly half-sat and half-fell onto it.
Isabella, her eyes aflame with lust, came down onto her knees between Holly’s feet and panted, “Let’s get those panties off.”
There was nothing Holly wanted more than to expose her slit to whatever Isabella was going to do to it. She raised her legs and ass off the mattress just long enough for Isabella to hook her fingers in her white panties and yank them off.
Holly raised her head to look down between her own thighs and was amazed. Where there had been a bald, featureless slit, there was now a poof of curly black hair above a set of complex, womanly folds.
“OMG,” Holly said, still staring at her own crotch. “Now that’s a pussy!”
“Oh yeah it is,” Isabella breathed.
Without a word of warning, Isabella thrust her face between Holly’s newly thick thighs and started eating the girl out with wild abandon. Holly screamed with the sudden, unprecedentedly intense pleasure and threw her head back even as she opened her legs wider for Isabella.
Isabella eagerly tongued Holly’s clit, then sucked it while fingering the girl’s pussy-hole. Then Isabella’s fingers and tongue switched places so that she was simultaneously tongue-fucking Holly and rubbing her clit at the same time.
“Oh God!” Holly screamed. “Oh God! Oh God! OH GOD!”
Her thighs seized Isabella’s head as Holly came, but Isabella wouldn’t stop eating Holly’s delicious pussy. At least, not until Holly sat up and rasped, “My turn.”
The orgasm might have been the most intense of Holly’s young life, but the pigtailed Fireside Girl was nowhere near sated. With the speed of a bantamweight wrestler, she moved around behind Isabella, who was still on all fours. Then Holly began to voraciously lick and tongue Isabella’s little pink asshole.
“Oh! Oh my gosh!” Isabella screamed. Not only had she never expected Holly to tongue her ass, but she never would have expected it to feel this good.
Even as Holly firmly caressed Isabella’s asshole with her tongue, she also rubbed the lead Fireside Girl’s clit and finger-fucked her pussy, making Isabella shriek incoherently with pleasure. And then, just when Isabella thought the stimulation couldn’t be any more intense, Holly plunged her tongue deep into Isabella’s little pink hole, and Isabella raised her head and screamed at the ceiling like an animal as she came hard.
But Isabella was no closer to being done than Holly was. So Isabella rolled over onto her back, pulled Holly on top of her, and tongue-kissed her savagely while mauling Holly’s big breasts with her hands. Holly kissed Isabella just as fervidly as she reached down and pushed two fingers into the little Latina’s pussy and a third finger as far up her ass as it would go.
After minutes of this intense and passionate exchange of sexual pleasures, Isabella pulled her mouth away from Holly’s and, gasping for breath, only barely managed to say, “Sixty-nine.”
That was all Holly needed to hear. The pigtailed girl rapidly reversed her position on top of Isabella and seized her troop leader’s face between Holly’s chocolate thighs even as Holly buried her own face in Isabella’s black-tufted pussy.
The two girls ate each other out with enthusiasm that bordered on mania. Isabella sucked and tongued Holly’s clit like it was the most delicious hard candy ever to exist, while Holly repeatedly plunged her tongue as deep as it could possibly go into Isabella’s love tunnel. At the same time, each girl grabbed two big handfuls of the other’s tits to squeeze and maul in their desperate lust.
It didn’t take even a minute of this before Holly, her tongue buried in Isabella’s pussy, cried “GUUUUUUUH!” as she came. Isabella, unwilling to release Holly’s clit from her mouth for even a moment, screamed “NNNNNNHHH!” and came along with Holly. Each girl’s soft, thick thighs squeezed the other’s face.
When their orgasms were over, the two girls lay there gasping. But as intense as her orgasm had been, Isabella knew she needed more. So she rolled off of Holly and turned around to look at her face.
“Let’s get the toys,” Isabella gasped eagerly.
“Oh, definitely,” Holly replied.
The naked girls went over to the cabin’s secret gear locker, opened it, and looked at the troop’s brand-new stash of sex toys. Ginger had taken one of the vibrators and the graduated anal beads, but there were still several items left.
“Let’s sixty-nine some more,” Holly said. “But this time, we can use the toys, too.”
Isabella smiled naughtily. “And since we’re big girls now, we can use the biggest toys.”
She reached into the box and pulled out a rubber dildo that looked like a pony’s cock. “How’d you like to get fucked in the ass with this while I’m eating your pussy?”
“Oh, fuck, yes!” Holly replied. Then she, too, reached into the box. “And how about I fuck your ass with this?” she asked, pulling out a pink vibrator that had a rubberized surface and a diameter approaching that of a tennis ball can.
“Hell yeah!” Isabella answered.
They lubed up the toys thoroughly, then got back into their sixty-nine position, this time with Isabella on top. Holly raised her bent legs in the air to ensure that Isabella had unobstructed access to Holly’s asshole.
“Ready when you are,” Holly said breathlessly.
“Okay,” Isabella replied. “Here we go!”
She put the head of the well-lubricated rubber pony-cock against Holly’s asshole. Then Isabella pushed and watched with fascination as Holly’s little hole opened wider and wider until the tightly stretched ring began to swallow the thick rubber dong.
“Oh yes,” Holly panted. “Keep pushing…It’s so big…So big in my ass…”
With a horny grin, Isabella fed inch after inch of the dildo into Holly’s asshole until only the base was still outside the girl.
“Oh yes, oh God, that feels so good,” Holly breathed. “Your turn now…”
Isabella reached one hand back and used her fingers to spread her asscheeks open as best she could. Seeing how much Holly liked having that big dildo in her ass made Isabella even more eager to take Holly’s thick vibrator in her own little hole.
Like Isabella had, Holly started slow, placing the tip of the vibrator against Isabella’s asshole and then gradually pressing harder until the hole began to open.
Indeed, Isabella found the pleasure intense. The more the rounded head of the vibrator stretched her little hole, the more she wanted it to stretch her even farther open. It was as though her ass hungered for this erotic intrusion, and Isabella found herself pleading for more on its behalf.
“Please, keep going,” she begged. “I want more, more, more, more…”
Holly could not have been happier to oblige. She kept pushing until Isabella’s asshole was stretched to what appeared to be an impossible degree, somehow matching the vibrator’s immense girth. And then Holly watched with erotic fascination as the big fucktool eased into Isabella’s adorable little ass, penetrating deeper and deeper.
“Oh my gosh,” Isabella whimpered. “I’m so full…I’m so, so full…”
Even though Isabella now had an extremely womanly physique, her voice was as sweetly high as ever, and Holly found Isabella’s high-pitched sounds of pleasure so sexy that she wanted to make them louder and more frequent. Fortunately, the means to do that was right in front of Holly’s face.
So Holly raised her head, put a pillow under it, and began tonguing Isabella’s clit. The raven-haired girl let out a high-pitched moan. Thus inspired, Holly switched from tonguing to sucking, eliciting even more sounds of pleasure from the naked troop leader.
Despite her intense excitement, Isabella hadn’t forgotten to play her part. She bent her head down and started eating Holly’s pussy while using one hand to slowly push the big pony-dildo in and out of the girl’s asshole.
“Mmmmmhhh,” Holly moaned, her face now buried in Isabella’s cunt.
Each girl ate out the other with elan, variously licking her slit, sucking on her clit, and tongue-fucking her as deeply as her tongue could reach, all while they pleasured each other with their long, girthy anal toys. Soon, Holly turned Isabella’s huge vibrator all the way up while Isabella vigorously pumped Holly’s asshole with the horse cock. And then both girls were screaming and clutching each other’s faces with their thick thighs as they came like crazy.
“Again,” Isabella panted.
“Definitely again,” Holly breathed, and then they started eating and ass-fucking each other toward another climax.
***
By this time, Perry had managed to free himself from Dr. Doofenshmirtz’s rope snare by swinging himself up to a light fixture and using the heat of the bulb to burn through the rope while Doofenshmirtz ineffectually swatted at him from below with a broom.
“I need to switch to LED bulbs,” the evil scientist groused as the rope around Perry’s ankles burned through and fell away.
Now free, Perry launched himself off the light fixture into a flying kick, and his webbed foot smacked Doofenshmirtz in the face. Before the man could recover, Perry hit the self-destruct button on the Age-Inator, then leaped off the balcony and made his escape by parachute. He heard Doofenshmirtz shouting after him.
“Curse you, Perry the Platypus!”
***
Suddenly, there was another green flash in the Fireside Girls cabin, and Isabella and Holly’s bodies instantly returned to their normal, preadolescent size and shape. The two girls gasped—not at the sudden transformation, but because the thick toys in their asses now felt absolutely gigantic. Gigantic, and very, very good.
“Ohmigosh!” Isabella screamed as the enormous dildo vibrated vigorously deep in her ass. “I’m gonna cum, I’m gonna cum!”
“Me too!” Holly cried. “Oh God oh God oh God!”
She seized Isabella’s face between her thighs, and Holly seized Isabella’s, and it took only a moment of frenzied pussy-eating before the two entwined girls were screaming and thrashing in ecstasy.
“Oh…my God,” Isabella panted. “That…was…incredible…”
“Uh-huh,” Holly gasped. “Don’t take…the dildo…out of me…I wanna…go…again…”
“Oh, yeah…” Isabella breathed. “Let’s do it again…”
Isabella continued slowly fucking Holly’s asshole with the rubber pony-cock, then resumed eating the girl’s pussy, taking her time with it this time. Holly moaned and started eating Isabella’s puffy pussy in return.
“MmmMMMmmm,” Isabella said in between licks of Holly’s bald slit, “I think I like eating your pussy even better this way. There’s no hair to get stuck in my teeth.”
“Yeah,” Holly said. “And your pussy tastes sweeter now—like blackberries.” Then she hummed “Mmmm” as she resumed licking.
Slowly, Isabella and Holly increased the intensity of both their pussy-eating and their anal play until they were vigorously tongue-fucking each other and Isabella was pumping the pony-dildo hard and deep in Holly’s ass while Holly turned Isabella’s anal vibe up to maximum. Soon, both of them were screaming in orgasm yet again.
“Oh wow,” Isabella panted. “I think…I’ve had…all I…can take.”
“Me too,” Holly gasped.
Slowly, each girl eased her huge sex toy out of the other girl’s ass. Then, just as slowly, Isabella and Holly sat up and gave each other a goofy grin.
“I think,” Holly said, “as far as my ass goes, I just became a size queen.”
“Oh yeah,” Isabella replied. “And I definitely want to do that some more.” She gave Holly a naughty smile as she added, “Patch or no patch.”
