(insert another rock joke here)
It was another fairly standard afternoon at Sugarcube Corner; its three residents currently busy working in the kitchen on a large order of sweets and confections for one of the many clients around Ponyville. Amidst the din of kitchen appliances and various manual tools being used, the sound of the door opening managed to make it all the way to the back of the kitchen and to a certain pink mare's ears, which perked up just as she turned to glance in the direction of the front door.
"Just a second!" Pinkie's voice echoed out from the kitchen of Sugarcube Corner in response to the familiar jingle, adjusting her apron and brushing off a dusting of flour from it. After putting a couple trays in one of the ovens, she leaned back and peeked around the corner of the double-door, suddenly grinning wide to the sight before her.
"Oh, Mrs. Cake, Mr. Cake, I gotta take a break like right now!" she added amidst excited giggles, practically throwing off her apron and zipping around through the double-doors, out to the front room, where standing at the counter was none other than her sister, Maud Pie. "Maudie! I missed you so much!" she nearly tackled the other mare with a firm hug, giggling wildly.
"Pinkie, I've missed you too." Maud replied, her usual facial expression remaining unchanged as her arms slowly came up and around Pinkie's upper body, gently returning the hug and feeling their soft chests squishing quite firmly together, behind their clothing. "It has been too long."
"Mmhm, it has! What have you been up to, huh?" Pinkie pulled back a bit, her big grin facing Maud's poker face now. "It's not often you come all the way out to see me!"
"Yes. I have been quite busy with my studies, lately." Maud continued, still holding Pinkie slightly against her side now. "I was recently at the Apple-lachian mountains. I came across a long, moist tunnel, with lots of quartz formations within. A short distance from it were many geysers, erupting powerful streams of boiling hot water." she explained, getting a few giggles from Pinkie. "It was entertaining, watching the high amounts of pressure building up further and further, and releasing in a powerful eruptions."
"Hehe, those don’t sound like sexual innuendos at all!" Pinkie giggled, hugging Maud a little closer again. "Anything else interesting that you've seen?"
"I also traveled to the shores of Griffonstone, where many stone pillars are located. Extremely large, erect stone pillars, constantly being brushed and stroked by the waves of the sea." Maud closed her eyes for a brief moment as she continued, "Every inch of the massive pillar, washed over with a cascade of smooth water."
"That sound sound at all like a sexual innuendo either!" Pinkie poked her tongue out, "But anyways...what brought you out here, sis?"
"I have come to see you because I am in need of your assistance." Maud answered, slowly unwrapping her arms from around Pinkie's body. "I have come to the conclusion that you are the only pony capable of assisting me." she stepped back while Pinkie looked further down; her eyes widening with another big grin as she gazed upon what appeared to be a massively oversized stallionhood between Maud's legs. Easily the length of one of her legs, if not thicker, it throbbed and pulsated in time with her heartbeat, seeming to be just as hard as the rocks she studied so much.
"Ooh, is somepony excited to see me?" Pinkie giggled and kneeled down, immediately wrapping both arms around Maud's massive member and hugging it against her body, nuzzling her snout against it as well, feeling each throb it gave. "When did you get this big? I don't remember you being this big!"
"That's the problem, Pinkie. I have been unable to ejaculate for approximately three weeks now." Maud answered, her expression remaining unchanged despite the pleasant physical attention her member was receiving, throbbing a bit more in response. "Nopony has been able to stimulate me enough to cause an orgasm. My penis has swollen immensely as a result of prolonged sexual arousal."
"Mm, not just that..." Pinkie smirked a bit now as she glanced between Maud's legs, seeing quite a huge, plump pair of balls dangling between them. "These look like they've swollen too!" she licked her lips and leaned in further, pressing her snout right between the two orbs and nuzzling at them, closing her eyes and inhaling the powerful masculine aroma. Without even thinking about it, her tongue slipped past her lips and began to slurp at the smooth spheres.
"Pinkie." Maud spoke, looking up from Pinkie now and over towards the door, though Pinkie seemed unfazed; continuing to slurp and nuzzle between Maud's balls, bringing her hands up and starting to massage them as well, lightly cupping and lifting them. Her fingers spread out and stroked along as much surface area as they could, getting quite a feel for the smooth, warm skin around the plump sack.
"Pinkie." Maud repeated, looking down at her sister again, watching her eagerly worshiping the huge grey spheres, already milking out loads of pre from the gigantic cock above. "Pinkie."
"Mh?" Pinkie finally looked up from her sister's thighs, her motions coming to an abrupt halt as she pulled her snout back a bit, licking her lips. "What is it, sis?"
"Pinkie, I think we should relocate to a more private area." Maud looked up again, followed by Pinkie turning her head to look back as well, both of them seeing the Cakes standing in the doorway to the kitchen with wide eyes; Cup Cake looking quite horrified, while Carrot Cake was pitching quite a tent in his apron.
"Oh yeah, hehe...I guess I'm even more excited than you are." Pinkie blushed and giggled, gently patting Maud's balls a couple times before standing up again. "C'mon, let's go up to my room!" she added with a big grin, before running off towards the stairs, Maud turning and slowly following.
"Uh, honey..." Carrot Cake spoke, gulping softly as he turned towards his wife, who was sporting quite a dissatisfied look. "I think I uh...need to take a break too...upstairs..." he grinned nervously, starting to edge away from the mare, who only glared a little more.
"Oh, no you don't!" Cup Cake grabbed the tent in Carrot Cake's apron, giving it a firm squeeze and eliciting a groan from the stallion. "You're not going anywhere until you give this cupcake a cream filling!" she barked while her other arm wrapped around him, pulling him closer. "With extra glaze, too!"
"Y-yes dear..."
~Fifteen seconds later~
"How's this, Maudie?" Pinkie giggled as she walked into her room, running over to her bed and jumping up onto it, her hefty chest and butt jiggling quite a bit amidst her light bouncing on the bed. As she turned over onto her back, she grinned over towards her sister, seeing her just entering the room. "C'mon over here, sis, and I'll work my magic on your big wand...hehe!"
"You're hilarious as ever, Pinkie." Maud spoke as she closed the door behind her, turning to see her sister lying across the bed, exposing her now nude body. Despite Maud's neutral expression, the eager twitching of her massive member easily showed how excited she was; a couple drops of precum splashing down onto the floor. "I am prepared to receive sexual stimulation now." she stepped up to the side of the bed, while her cock lightly bobbed up and down in front of Pinkie.
"Coming right up!" Pinkie poked her tongue out, sitting up on her bed and reaching forward, grabbing at the first couple feet of Maud's length with both hands. "Don't worry Maudie, I'll relieve those blue balls of yours." she grinned again, starting to stroke and rub her hands over her sister's cock as she leaned in closer, slipping her tongue out again and starting to slurp over the flared tip.
"That feels pleasurable." Maud's cheeks instinctively blushed in response to the teasing pleasure, watching as Pinkie rubbed and licked at her massive member, which happily throbbed and continued to gush sizable loads of precum, splattering onto her sister's face and chest. "Continue, Pinkie."
"Mmmnhm..." Pinkie grinned a bit wider and lidded her eyes, pressing in closer and nuzzling firmly against the tip of Maud's member, continuing to slurp over it while her hands made longer strokes up and down the length, her fingertips brushing over the medial ring and lightly teasing it as well. A few licks later however, she began to open her mouth and push a bit more firmly against the tip of the oversized cock. Even with her jaws spread as much as she could, Maud's girth still didn't fit inside, though the party pony still tried her best to suckle on it with her lips and continue slurping her tongue over the tip, gently squeezing at the medial ring with both hands.
"Pinkie, you know that you're unable to fit my penis into your mouth." Maud placed her hands on top of Pinkie's, only getting a playful look from Pinkie. "Please do not injure yourself in an attempt to."
"Mmnhheehe..." Pinkie giggled softly as she pulled back, sliding her hands back again and rubbing near the tip of Maud's cock. "One of these days I'm gonna fit it inside! Just you wait!" she stuck her tongue out again, gently patting the head of Maud's cock with one hand, while her other continued to rub it. "And I'm sure it feels good even if it's just my lips and tongue, right?"
"Correct. But I still fear for your safety, Pinkie." Maud continued, her cheeks still lightly blushing from the teasing pleasure her member was receiving. "Shall we proceed to penetrative sex?"
"That's just what I was thinking!" Pinkie's lustful grin turned to an excited one while her hands rubbed Maud's length a little faster, squeezing it some more as well. "If stuffing this pie doesn't cure your blue balls, I don't know what will!" she giggled again, leaning in and kissing the head of her sister's twitching dick before turning around on the bed and getting down on all fours, playfully wiggling her fat rear a bit. "C'mon, sis! Pump this pie full of your sweet cream!"
"Yes. Here I come, Pinkie." Maud moved up a bit closer and reached out with both hands, gently grabbing the sides of Pinkie's plump posterior. "I'm inserting my penis now." she added before pushing her hips forward and penetrating her sister's snug rear, eliciting a pleased moan from her.
"Oohh, yeah...stick it deep in me, Maudie..." Pinkie moaned, grasping at the sheets already as she leaned her upper body down a bit further, pressing back a bit against Maud's cock as it gradually pushed deeper and deeper inside her. "Might not be able to fit it in my mouth...but you can definitely fit it in my butt!"
"Of course. Your anal cavity is firmly squeezing around my penis, Pinkie." Maud spoke, softly panting now as she pushed her hips further forward, tightening her grip on Pinkie's butt as well. "This is very pleasing to me."
"Nnhhyeahh, keep going...ah!" Pinkie groaned and blushed with each push from her sister, feeling the oversized cock lurching deeper and deeper inside her, now starting to bulge her belly out in its shape from how insanely deep it was penetrating her. "Push it all inside!"
"I am almost all the way inside you, Pinkie." Maud's eyes lidded ever so slightly as she pushed more, only a few inches of her monstrous length still outside the pink mare, a soft grunt escaping her throat with her final thrust, feeling her crotch gently clap against Pinkie's bubble butt. "Pinkie, Your rectum feels prodigious."
"Glad to hear it, sis!" Pinkie grinned back at the futa mare, lightly wiggling her hips while she enjoyed the steady throbbing of the monstrous phallus within her rear. "Now come on and stuff this pie full of cream!"
"Yes. I will release copious amounts of semen within you, Pinkie." Maud replied as she leaned forward a little, tightening her grip on her sister's hips before beginning to steadily buck her hips back and forth, already starting to ooze warm precum. "Are you enjoying this, Pinkie?"
"Oooh, it's a start!" the bubbly pony moaned, leaning her head down and looking down at her belly, watching it repeatedly bulge out every time Maud thrust her hips forward, her pink melons also jiggling quite a bit from the steady humping. "You can go harder than that though...mmnh, I know how strong you are!"
"Of course. I will thrust harder for you." Maud was beginning to lightly pant again as she immediately picked up the pace, making quicker, more firm thrusts into Pinkie's snug butt; the powerful motions causing her huge balls to swing back and forth quite a bit. "Pinkie. I can feel my testicles colliding with your vagina. It is pleasurable."
Already, Pinkie was gasping and groaning blissfully, a huge grin on her face as she leaned her head back again. "Ahh...yeah...stuff me hard, Maudie!" she moaned, a light blush crossing her cheeks as well, while her tight rear continued to squeeze around her sister's length. All the while, further loads of precum soaked her insides, only making it easier for the hyper-endowed mare to thrust.
"Yes, Pinkie. This is...highly stimulating." Maud was panting a bit more now, starting to get slightly fatigued from her powerful thrusting; feeling her orgasm steadily building up as well, signaled by more frequent throbs from her massive member, along with further loads of precum pumping inside the bubbly party pony. "It's working, Pinkie. I can feel my pleasure rising further and further."
"Glad to, nhh, hear it!" Pinkie gasped between her fevered panting and groaning, each firm thrust pushing her whole body forward against the bed, causing her chest to heave back and forth, until she suddenly felt them being squeezed. "Ah, Maudie!" she gasped, shuddering softly from the surprise squeezing her chest was receiving, looking back over her shoulder to see Maud leaning over forward, her own huge chest lightly swinging back and forth with her movements.
"Pinkie....I'm going to ejaculate." Maud softly groaned, her eyes lidding quite a bit now while her cheeks blushed heavily. With each throb her cock gave, a fresh gush of precum flowed forth, soaking the pink mare's insides with its hot stickiness. "I'm...ngghh..." she grunted, her eyes fully closing now as the pent-up pleasure began to overwhelm her mind.
"Come on, Maudie! Open the, ah...floodgates!" Pinkie was deeply blushing now as well, squeezing the sheets tightly while her snug rear did just the same to Maud's throbbing length. Only a few powerful thrusts later, she felt her sister give one last hump before what resembled a pleased moan escaped her throat, followed by a huge torrent of steamy seed.
With her pent up lust finally releasing, Maud's grip on the pink melons tightened while she kept her hips pressed firmly to Pinkie's plush posterior, lightly shuddering with every throb her cock gave, feeling it pump load after load within her sister. After only a few gushes, Pinkie's belly inevitably began to distend outward, swelling larger and rounder with each new load of seed that was forced inside her.
"Ooohh yeah...s-so much...cream!" Pinkie's eyes rolled back as the huge torrents of warmth poured into her belly, her tongue lolling out of the side of her mouth amidst her heavy panting. Already, her belly was swollen to look as if she were close to given birth, but it continued to swell even further; Maud's orgasm still going strong, emptying out the tons of pent-up seed in her balls.
"Yes...the quantity is very large..." Maud softly groaned, panting heavily with her sister as she basked in the potent pleasure that was coursing through her body, still firmly gripping Pinkie's melons while her member pumped and pumped; her once overly-swollen balls quickly shrinking back down to a more normal size, though her engorged length seemed to remain that way, keeping a vast majority of her seed inside the pink mare's belly.
"Nnnh, Maudie...you're stuffing your pie so full!" Pinkie groaned out loudly, her cheeks flushing a deep shade of pink as her hands slid back to her now quite massive midsection, stroking over her immensely bloated gut and feeling it still distending even further with each throb of her sister's dick. "So much...cream..."
The pink pony's words seemed to be ignored though as Maud continued to unload inside her, too lost in pleasure to focus on anything else at the moment; her hands still firmly squeezing at her sister's chest while she enjoyed each wave of pleasure from her constantly-throbbing length. After nearly thirty seconds of constant pumping, the flow of seed finally slowed to a stop, leaving Pinkie with an incredibly bloated belly, easily half the size of the rest of her body, even!
"You were...ahh...a lot more pent up than I thought!" Pinkie groaned, laying on her side now with both hands rubbing across her insanely huge gut, feeling it lightly wobble a bit as her sister's hot cum sloshed around inside her.
"And you have helped me release it all." Maud replied, still lightly panting in the wake of her orgasm; a powerful afterglow making her feel a bit light-headed as well. Standing up again, she slid her hands off of Pinkie's soft chest and grasped her hips, pulling her own hips back and sliding her cock out, only to notice that it was still just as big and hard as ever. "This is strange. My penis is still heavily engorged."
"Hhmmm..?" Pinkie looked back as she felt the oversized member sliding out of her butt, gasping softly once the flared tip came out with a slight 'pop'; clenching her anal muscles firmly so as to prevent too much of her sister's seed from escaping. "Still hard? Wowie!" she grinned a bit, glancing back at Maud and seeing that monstrous futa cock sticking straight up, indeed still hard as ever and lightly bobbing in time with the mare's now slowing heartbeat. "Well, hehe...if you're still rock hard, I guess I'll have to help squeeze even more cream out of you!"
"Yes, I believe that would be the most logical course of action." Maud brought a hand up and gently stroked her twitching stallionhood a couple times, pushing it down and aiming it towards Pinkie's backside again. "Let us proceed to the second round of sexual intercourse, Pinkie."
~About three hours and countless orgasms later~
"Well if you ever need some more sweet release, you know where to find me, sis!" Pinkie giggled and hugged her sister again, gently nuzzling her cheek. "That was more fun than I've had in a while!"
"Yes. That was very entertaining. I am feeling quite well, now." Maud replied as she hugged her sister in return, inevitably getting a face-full of frizzed pink hair for a moment before the pink mare leaned back again. "If I ever find myself unable to ejaculate again, I will seek your assistance. Goodbye."
With that, Maud let go of her sister and exited through the front door, though Pinkie stepped up to the front door as well, hanging onto the doorframe with one hand and waving her other hand in the air. "Thanks for visiting Sugarcube Corner!" she cheerily called out, getting quite a few startled looks from nearby ponies; her frizzed mane and tail and white-splattered body giving quite a clear indication of what she had been doing with the futa mare who was walking away from the building.
"Pinkie, dear?" Cup Cake's voice called from within the bakery, prompting the mare to turn around, seeing the baker herself standing in the doorway to the kitchen, with her mane and coat looking quite similar to Pinkie’s. "Are you finished with your break?"
"Hehe, yep! Ready to get back to work now, Mrs.Cake!" Pinkie giggled as she hopped over to the counter, grinning eagerly at the older mare before raising an eyebrow to the sight of her body. "Oh wow, you two have been really working while I was gone, huh? Did the mixer arm come loose and splash cake batter everywhere again?"
"Mm, well...a certain cake's batter, yes..." Cup Cake giggled softly as well, leaning against the door frame. “You really should bring your sister over here more often though, Pinkie.”
“Really? What makes you say that?" Pinkie tilted her head to the side, still grinning a bit though at the thought of inviting her sister over again.
"Your sister made my husband more virile than he's been in years!" Cup Cake blushed lightly and grinned again, crossing her arms beneath her chest and sighing happily. "It was like being a young, newly-married mare all over again..."
