The Non Cannonical Sequel to Boundaries.

The Apple sisters rode in utter silence for most of the long ride from their farm towards Canterlot High. Normally the rather close siblings would chatter like monkeys or, if there was no conversation to be had at the moment, Applebloom would pick a station on the radio and the two would sing along, off key, to classic country tunes. Yet today the younger sister sat silently stewing. Applejack, in her wisdom, decided that it was better to deal with stew sooner rather than later before it could boil over. "Alraght, Ah'll bahte. What's got ya all sour faced?"

Applebloom silently slapped a condom wrapper down on the center console. The older sister felt her blood turn to ice in her veins. She'd been so careful! She'd counted! It was only the fact that they were on a long straight away that kept them from going off the road. The younger sister piped up accusingly, "Ah'm in health class Sis. Ah know what that is!" Applejack glanced at her sister, waiting for the other shoe to drop. "How could you Applejack!"

That confused the elder sister for a moment. "How could Ah what?"

Applebloom pounded her tiny fist on the center console. "How could ya cheat on Rainbow Dash?! Ah know what those are for! Those are to catch a boy's ejaculate!"

Applejack almost vomited at hearing her baby sister discussing sex matters. No matter how old or mature either of them got it would never not be creepy to discuss sex matters with family members. "Now A.B. settle down. It ain't what you think!"

There were tears in the younger sister's eyes as she shouted, "That's what they all say! And y'all just made a big deal about confessin to Granny! She LOVES you A.J.! And you're goin behind 'er back with some feller?!"

Applejack tried to keep her calm about the situation as she tried to get a word in edgewise. "Look Sis, just listen! We."

Applebloom gasped. "Unless! Don't tell me you're one a those couples that's okay with just runnin around on each other! Say it ain't so A.J.!"

The older sister decided enough was enough. She pulled over the truck and shifted it into park. She stared at her glaring sister for a long moment before speaking. "Applebloom. Y'all'r a big girl now." She scoffed. "Yer in health class n everything. N Ah'm vureh prad uh ewe. So Ah know Y'all'r old enough to keep a secret."

Applebloom's eyes went wide then narrowed. Before the older sister could stop her she cracked the door open so that Applejack couldn't lock her in. "Ah ain't keepin any secret that's gonna hurt nobody A.J.."

Applejack nodded approvingly. "Good. Ah'm glad y'all got a head on your shoulders. Now Ah need yer oath on yer word uh honor that what Ah'm about to show y'all don't leave this truck."

The younger sister's narrowed eyes shrank to slits on her yellow face. "That's exactly what someone says before they say er do somethin terrible."

The older sister remained firm. "Ah swear on Ma n Pa's headstones, it ain't nothin that hurts nobody, but it vury personal. Promise me!"

Applebloom rolled her eyes and raised her right hand. "Ah swear on mah honor that what y'all'r about to show me don't never leave this truck."

Applejack nodded sternly. "Now you know about the magic from that pony world that spilled into are's right?"

The younger sister brightened slightly, "Yeah! With Sunset n all that. But now she's y'all's friend."

The older sister nodded again. "That's raght, n y'all know about Rainbow's wings n mah super strength?"

Applebloom pouted, "Yeah! Lucky."

Applejack chuckled to herself, "Yeah, well it ain't so great when yer tryna build a dock. Well. . ." The blonde had to prepare her soul for what came next. "Turns out the magic ain't all used up just yet, n on frahdee somethin went haywahre. It. . . Changed, me n R.D."

"Is that whah yer boobs are so big all of a sudden?" Applebloom asked, frowning at her own B cups.

Applejack nodded. "Yes, but that's not the biggest thang. Now A.B. Ah need ya to swear what Ah'm about to show you never leaves this truck!"

"Ah already gave ya my word didn't Ah?!" The younger sister snapped, feeling that her sister was trying to distract her from her wrongdoing.

Applejack nodded. "Ya did. Now. . . Trah not to. . . Freak out on me."

Applebloom frowned. "Sis, Ah'm fourteen. Ah can handle mahself."

"Oh lahke ya did at the theater?" The older sister asked teasingly.

The younger sister grew red faced and once again smashed her tiny fist against the arm rest. "Hey! That alien poppin outta that lady's chest freaked you out too!"

Applejack sighed, "Well, this thing pops out at inconvenient tahms too." Applebloom raised an eyebrow high on her head. The older sister took a few deep breaths and began massaging her large breasts. The younger sister tightened her grip on the door, worried that her sister might be about to do something unnatural. There was no way she could've been prepared for what happened next. Her eyes grew to the size of dinner plates as a foot of orange flesh appeared sticking out of her sister's pelvis.

The world went black for some time, and she came back with a start, on the ground, her sister shaking her slightly. She swatted her hands away and scuttled back several feet in fear. Applejack raised her hands disarmingly. The younger sister's eyes shot down to between her sister's legs and she was relieved to see no orange appendage sticking out of her. She gasped for breath and vomited up most of her hearty breakfast onto the grass beside the road. She heard the door to the truck squeak and was dimly aware that her sister was giving her as much time as she needed.

Applebloom took a moment to breathe the warm late spring air and recover from her shock. She slowly slipped back into the cab and firmly shut the door. She saw her sister offering her a red and white polka dotted handkerchief and she wiped her mouth with it. "Did. . . Did Ah just see what Ah think Ah just saw?" Applejack nodded. The pale girl turned slowly to look at her sister's crotch under the baggy pants. "So you've got a. . ."

"Not all the tahme. Only when Ah'm. . . In the mood, as it were. It acts like R.D.'s wings. But we found out that if the. . ." Even though they were past the highest hurdle, it was still awkward. "If my. . . Stuff. . . Gets in er, it makes her bits bigger. Well she's even bigger n me, so we got these to keep the. . . Stuff. . . From gettin in. Ya understand?"

Applebloom leaned far in, shock and concern written on her face. "Y'all use that thang?"

Applejack shifted uncomfortably. "Y-yeah. . . Often."

"R.D."

"Yes."

"The lesbian."

Applejack frowned and scoffed. "Yes! Rainbow uses my cock! Hell, turns out lesbians give the best blow jobs apparently."

Applebloom bobbed her head in assent. "Yeah, that's true."

The older sister did a double take at her sister's complete acceptance of the supposed fact. She sighed, "We tend to think of it as just a magic strap on. It only appears when we're in the mood, then it vanishes. But we can't cum inside no more, so we gotta use. . ." She held up the condom wrapper. "These." She flopped it down. "Do ya understand?"

The younger sister sat contemplatively for a long moment. "Does anyone else know?"

Applejack sighed, "Yeah, mah friends. It's me, n R.D. n Sunset, n Fluttershah, we was all in range when it happened. Then Pinkie n Rarity got in on it later."

"What about Twahlaght?" Applebloom asked.

"Naw she weren't there when it happened. Me n R.D. helped Pinkie get all swolled up. N the other'n's helped Rares." She looked, almost pleadingly, at her younger sister. "Now ya see? There weren't no boy. It's me. Do ya understand?"

Applebloom sighed hard and looked out the window. "The thangs you get up to girl. Come on were gonna be late for school."

Applejack smiled and put the truck into drive. "Sorry to have to give y'all such a shock first thang inna mornin." She couldn't repress a small chuckle.

Applebloom threw her hands in the air in exasperation. "Ah'm sorry to accuse ya of sleepin around! But y'all know ah woulda NEVER believed ya iffn ya hadn't a shown me!" She gave a hissing laugh and soon the two were laughing together all the way to school. They parked and before she had taken two steps Applejack's vision was completely filled with big blue titties.

"Apple Top!" Rainbow shouted, wrapping her arms and legs around her lover. "You're late! Keeping your succubus waiting! Cruel goddess!" Applejack couldn't help but grin and enjoy carrying her lover, giving her a smiling kiss. Rainbow noticed the younger sister, staring pale faced at them and waved, leaning far back and extending a leg. "Sup squirt! How's Scoots?"

Applebloom froze in terror. She looked from the bimbo's blue face to her enormous proportions and back to her face. Three days ago the fourteen year old had larger breasts than the blue woman, now each of the bimbo's jiggling jugs were larger than her head. She couldn't help but steal a glance at her sister's nether regions and to her relief there was no visible bulge. "Uhm, she's big. BLUE! GOOD! UHM, Ah'll see y'all after school A.J.! BYE!" She scuttled away as fast as her legs could carry her.

"What's her deal?" Rainbow asked, still not dropping off of her perch on top of her lover.

Applejack sighed hard. "She fand one uh the wrappers."

Rainbow gasped. "Nuh uh! We were so careful! What did you tell her?!"

"The truth. All of it." The farmer said with a disarming calm.

"And she's just okay with that?" The bimbo asked skeptically.

Applejack sighed, "It freaked 'er out a little, but she'll be fahne."

"Why didn't you just say it was one of Big Mac's?" The succubus asked.

The blonde woman stood silent for a long moment. "Fuck. . . Well, truth be told, cuz Ah didn't thank uh that. But you know me, 't's better to tell the truth anyway."

The succubus got a mischievous idea. "Speaking of condoms!" She rubbed her big blue breasts on the farmer's face. "We've got some time before." DING!!! The school bell rang and destroyed the succubus schemes of pre class coitus.

"Sorry Sucky Butt. Looks lahke you'll have ta wait." Applejack said with a grin as she gave her lover a firm slap on the ass.

Rainbow immediately dropped to her knees and pleaded pathetically. "Oh come on! We've got a whole five minutes before class starts! Just a quickie to tie me over until lunch? Please! Please! Please!" She pouted her big beautiful dick sucking lips and whined like a dog.

Applejack straight arm lifted her into the air by the collar like a puppy and began her march towards the school. "Nuh uh ya dirty succubus! Ya ain't temptin me this mornin! Git ta class!"

The horny succubus pouted and crossed her arms and legs. "Oh you are gonna GET IT in athletics!" And she did get it in athletics. More specifically she got it immediately after athletics. During athletics she got the cock tease of her life. They were doing relay races in class and the succubus made a point of tempting her goddess as hard as she possibly could. Both lover's had to request larger uniform sizes, but Rainbow was cruel about it.

Whereas Applejack's inflated frame made the athletics uniform fit tight anyway, Rainbow intentionally went one size too small. Her jiggling breasts stretched the fabric of her shirt to the point where every thread was tensed tighter than bailing wire. Her enormous ass hung halfway out of the short shorts, showing off her long thick thighs. She still wore her long rainbow hair in a tight ponytail, both tempting her goddess with the handle, and displaying the long blue neck that the bimbo enjoyed having squeezed so very very much.

The relay races were such that one had to sprint to the end of the hundred meters, turn around, then sprint back the hundred meters. Rainbow and Applejack weren't assigned to the same team, but the succubus bullied and glared until she stood in front of her lover. She stuck her ass out needlessly far and wiggled it teasingly at her lover, the tramp stamp peeking out above the waistline beneath the t-shirt. The blonde had to breathe deeply and stare straight ahead to avoid showing the entire class something they were NOT prepared to see.

Rainbow still led the class in the sprint both ways, not only because of her magical super speed, but quite possibly because several of the other runners wanted to be able to watch the enormous blue ass as it shook and shifted while she ran, not to mention several of them were having a similar problem to Applejack. The blonde got the worst of it, not only being madly in love with the succubus that had every eye on her, not only because she'd had the big blue jiggling body, and it was even better than it looked, but because she was standing right in front of her when the fantastic ass became a view of the giant jiggling jugs as they flopped towards her.

She couldn't look away as she needed to take her turn the second that the charging succubus got to her. She had to watch the entire time as the enormous breasts in the tight t-shirt bounced and jiggled towards her. It took every scrap of will in her inflated body to keep the magical appendage from presenting itself. The blonde could swear the succubus was intentionally running slower to drag out the torture. Finally the blue woman made it back to the starting line and slapped the orange hand.

Before Applejack could take her first step Rainbow turned and slapped her ass hard. Applejack reflexatorily let out a loud pleasure moan, making the uncomfortable situation for the young men of the class even worse. She had lost the head start that her lover had worked so hard to give her and she waddled as quickly as she could towards the hundred meter mark, thanking her lucky stars that her lust felt content to keep itself contained. She reached the end last and turned back towards her lover.

Every eye was on the jiggling farmer as she ran, so no one noticed a blue arm hold up something that reflected the bright late morning sunlight. The succubus was propping her big blue breasts together and in her hand was something that Applejack couldn't exactly make out in her sprint. As she neared the small square became clearer and clearer, it was black, about two inches square, the edges were crinkled.

The blonde realized all of a sudden what her succubus had in her hand and instantly she was at the front of the pack. The temptress was holding a condom, spurring her on in the worst way possible to her reward. Applejack reached the end of the race by a wide margin, but instead of stopping she charged straight at her lover, who leapt into her arms. She didn't stop her sprinting pace or slow by a single second as she charged towards the concealment of the far bleachers.

The coaches watched in concern at the retreating couple. They gave each other a questioning look, asking each other if they should intervene. Both decided that they would never forgive anyone who stopped them from making love to either of the curvaceous women, so they decided to let the two alone. Applejack was condomed, inserted, and pounding away without the succubus having ever touched the ground.

The goddess pressed the succubus against the wall and actively tried to force her throbbing cock straight through her and into the concrete behind her. Rainbow aided the effort by wrapping her arms and legs around the thrusting orange woman and pulling her into herself as hard as she could. The blonde felt herself getting close and hissed between tightly clenched teeth, "Where?"

Rainbow had to gasp for breath several times before being able to whisper, "Mouth!" Applejack dropped the succubus and rammed her cock down her throat without a moment's pause. Rainbow sucked as hard as she could, actively trying to break her own nose against the orange pelvis. With one fluid motion the bimbo pulled the cock out of her mouth, tore off the condom and shoved the cock back into her mouth. Applejack had to hold the blue head as her climax shook her to her very core, her legs trembling with the shock.

The succubus caught all of the cum in her mouth, continuing to suck the head while licking the underside and stroking the shaft with her hands. She felt the thick orange legs stop trembling and the dick faded out of her mouth. She tilted her head back and showed the overful mouth with stars in her eyes. Applejack had to brace herself against a wall, her head spinning with the orgasm. "Why'd'ya. . . Take off. . . The condom?" She asked between huffs and puffs.

Rainbow took the used condom and gently let the cum leak into it, showing her empty mouth afterward. "A little fucked up to leave giant puddles around the school don't you think?" Applejack stared in lust at the squatting succubus. The bimbo was about to tie off the condom to prevent it from leaking out, but her goddess put an orange hand on the top of her head.

"Hole up, y'all got another condom on ya?" Applejack asked, a determined gleam in her eye.

The bimbo pouted her big pouty dick sucking lips out at the blonde. "Sorry goddess, I only grabbed the one." Her eyes sparkled when the magic dick reappeared.

"Then don't tah that off just yet." The goddess whispered as she shoved the orange dick down the blue throat. She had to grit her teeth as she growled, "FUUUUUUUCK! Lesbians DO give the best blow jobs FuUuUuUuck."
