“I don’t know Twilight. I just haven’t been feeling well.”
The alicorn nodded sagely, taking in Pinkie’s concerns. Two hot cups of tea rested on the table between them. “I see. Have you… ya know… had any release lately?”
Pinkie bit her lip and shook her head, her curls bouncing like springs. She hadn’t told any of her friends about her extra parts except Twilight. The only other ponies who know were her family, and the Cakes, each bound by the most sacred Pinkie Promises. It was thanks to Twilight and her magical obfuscation spell that other ponies didn’t get an eyeful of mare meat every time she bounced around town.
“Well, Pinkie, I think you should let off some tension, so to speak.”
“I want to, but every time I try, I think how much of a freak I must be to everypony else. Then, I just stop,” Pinkie admitted, her shoulders drooping.
Twilight left her seat and grabbed a box off a nearby table. She walked over to Pinkie Pie and placed it in her lap. “Here. Next time you try, use this. I bet you won’t think of anything else… and you’re not a freak, Pinkie Pie. You’re a wonderful pony who makes everyone smile.”
The pink pony gave a smile of her own and grabbed Twilight in a hug. “Awww, Thanks Twi. You’re pretty wonderful yourself.”
Twilight beamed and drank in the pony’s affections. Secretly, she dreamed she could hug Pinkie whenever she wished. She wanted so desperately to confess her adoration of Pinkie. Alas, she could never find the courage to do so, and this hug, like all hugs, had to end without the promise of another one anytime soon.
Pinkie grabbed the box and shook it while biting her tongue. Twilight froze in place, her eyes bulging. “P-Pinkie! Don’t do that! It-it’s very delicate!”
“Ooohhh, okey doke! How does it work?”
Composing herself, Twilight coughed. “I think it’ll be pretty obvious when the time comes. However, just to be clear, you can only use it at night. It won’t work during the day.”
“Okay! If you say so. Bye, Twilight! See you around soon!”
“Bye Pinkie!” the alicorn waved from her seat.
The castle door slammed shut and Twilight squealed with delight. “Yes yes yes yes yes! It’s only a matter of time now.”
In truth, the box Twilight passed off to Pinkie had a very special device in it. It wasn’t some crude sex toy. It was a special portal with a grip linked directly to her own marehood… which is why she felt such discomfort when her friend shook the box. It had another spell on it as well. A spell which allowed her to hear everything within earshot of the device.
“Oooh, Pinkie. Please let me relieve you. I want to feel you so.bad.”
Twilight imagined Pinkie in her hooves, her supple rump, that hungry smile, her huge package. She wanted the party pony to throw her on the bed and take her like a mad mare.
“Soon,” Twilight moaned, breaking her reverie. “Soon.”
“Soon” fell away as the days turned to weeks. Every night Twilight went to bed hoping this would be the night. It never was.
“Grrrr. Aren’t we friends? Doesn’t she trust me?”
The alicorn paced in her chambers with a sour look drawn upon her face. “I mean come ON!”
Twilight’s ears perked up as the sound of a box being opened played out in her head. “What? Could it be?”
"Oh, oh, OH! I need this really bad!"
Twilight smiled with unbridled glee as Pinkie’s words echoed in her head. With one jump she landed on her bed with her face in her pillow. Her pert rump raised into the air, instinctively waiting for what was to come.
“Eeeeyah!”
Twilight screamed as she felt Pinkie’s hoof prod her marehood roughly. “Pinkie Pie! Stop that!” she cried out, even knowing the curious pony couldn’t hear her.
"Gee, it sure feels like the real thing. I guess being a smarty smart pants helps in all sorts of ways! Guess I’d better get my thingy ready."
Twilight breathed a sigh of relief. “Thank goodness.” Her own marehood started to dampen as she heard Pinkie stroke herself, getting her package ready for delivery, so to speak.
"Well, my thingy’s all hard, but I don’t have any lube! Oh well. It is just a toy."
An uneasy lump made it way down Twilight’s throat. “Uh oh.” She flinched as a drop of warm sticky liquid hit her marehood.
"I should just do it, or there will be a big mess like last time. Hard to believe it’s been six months since I played with myself."
“Six monthAAAAAGHHHHA!”
Twilight cried out as Pinkie’s massive cockhead stretched her pussy wide open. Gritting her teeth and pulling at the sheets, she suddenly realized this might have been a bad idea.
"It’s… so tight! So good! This is way better than a watermelon!"
Twilight’s butt wobbled and twitched as she struggled to maintain her composure. Her hoof flew to her stomach as Pinkie’s bulge showed through her coat.
“Nnnngah! It’s too much!” Twilight screamed. Yet Pinkie showed no sign of stopping. Inch after agonizing inch deformed her stomach until the massive meatstick hit her womb.
"What? Is that it?"
“Yes, Pinkie, that’s it! No more!” Twilight pleaded, hoping against hope the sex crazed mare would hear it.
"One more try…"
Twilight’s eyes bulged as Pinkie thrusted once more, spreading open the alicorn’s cervix and allowing the crazed pony entrance to her most sacred parts.
"Woo hoo! All the way in!"
Twilight did not share Pinkie’s enthusiasm. Slowly, she felt Pinkie’s cock pull back, leaving her with a brutally empty feeling. A vicious thrust sent the whole meaty pole back into Twilight’s depths. The alicorn’s pain soon turned to pleasure as Pinkie fell into a rhythm. Sticky globs of pre painted Twilight’s womb and canal, making Pinkie’s thrusting much more bearable.
"This feels so good! I bet this is what a real mare feels like."
“Nnnngh, unngh, uuurgh. You have no clue, Pinkie.”
Twilight’s clenched teeth soon turned to a dopey grin as the earth pony rutted her brains out from the other side of town. She could only hang on for the wild ride Pinkie was providing her with. Reaching beneath her stomach with her hoof, Twilight rubbed her marehood wildly.
Though Twilight was rapidly approaching her precipice, her expression changed to one of curiosity when she heard what sounded like a water balloon churning and gurgling as it filled from Pinkie’s side of the connection.
“Huh?”
Pinkie’s thrusting intensified as the churning grew louder.
“What in-hah-Equestria is that sound?”
"Gonna fill this thing like an eclair!"
It suddenly struck the alicorn that futa ponies were usually hyper productive, especially after long stretches of no release. Twilight’s eyes widened as she felt the meaty pole impaling her bloat in a sudden burst of growth. Thinking quickly, she put her hoof against the throbbing cock buried inside her and squeezed, hoping to keep the cum at bay until she could figure something out.
"Ouchies, ouchies, ouchies! It hurts! It hurts! I can’t release! I thought Twilight said this would help! It hurts!"
A sharp pang of guilt hit Twilight hard. Pinkie was just doing what she was told. It’s not her fault Twilight didn’t prepare for this.
“Oh brother. I’m going to regret this.”
Twilight let her hoof go. The first blast of cum forced her belly to bulge obscenely. She collapsed onto the bed, just in time for her bloated stomach to catch her. The next blast was even larger than the first, swelling her midsection like a beanbag. Burst after burst, gout after gout of cum exploded inside the alicorn, stretching her womb to absurd limits and raising her up on her cum filled tummy.
"Ooooh yes! More! More!"
“No, no! Less! Less!” Twilight pleaded.
With each spurt of cum, Pinkie thrusted, burying herself deeper into the alicorn.
Twilight had long since given up trying to estimate the amount of cum swirling in her bloated womb. Wider and taller she grew, far beyond the point where she could reach the mattress with her hooves.
“I’m… I’m nothing more than a cum balloon. When will she stop?”
An ominous creaking made her eyes widen. Her massively ballooned gut weighed down on her mattress as it protested her growth. With a final groan, it collapsed in a heap. Fortunately, the mattress still provided plenty of cushioning for her now spherical belly.
"Eeeeyah!"
An ear piercing orgasmic shout made Twilight flinch as Pinkie blasted one final burst of cum into her swollen belly, causing it to slosh like a waterballoon. It exploded outward another foot making Twilight nearly roll forward onto her face. Luckily, the immense amount of fluid inside her would not be budged so easily. In her head she could hear Pinkie’s desperate panting as she recovered from her orgasm.
"That…. was…. fantastic! And it didn’t even make a mess!"
Twilight groaned as she patted the so called mess sloshing inside her. Not only did she fail to climax, Pinkie’s wild lovemaking rendered her immobile.
"I guess I should go clean this thing up."
Twilight’s ears flicked as she thought over Pinkie’s words. A sense of worry built inside of her as she heard Pinkie Pie walk away from her bed. She heard a squeaky handle turn and running water. A lot of it.
"Cleaning time!"
Twilight shuddered as running water splashed across her marehood, stimulating her further. “Nnngh, Pinkie…” she panted as the pink pony dutifully cleaned her pussy.
"Huh. Maybe I should clean the inside good too."
“AAAGHaaaaa... “ Twilight cried out as she felt the bathtub spout violate her marehood. She gritted her teeth as gallons of water poured inside, pushing her belly to even greater sizes.
“Please, Pinkie… no more!”
Heedless of Twilight’s plight, Pinkie continued filling her “toy” with water.
"This is weird. It should be overflowing by now. Maybe it needs more?"
Twilight gasped as Pinkie turned both knobs to the max. Her gut bloated outward at an even faster pace, well and truly stranding the alicorn on top of her belly. Five feet, six feet, seven feet, higher and higher she rose on the rippling belly beneath her. Outward it stretched like a water balloon, fully covering the broken bed and expanding toward the walls. Wobbling her hooves across the vast expanse of her skin, she was rewarded with an intense burst of pleasure.
“Oh! Oh my!”
The pain, the fear, the anxiety, it all washed away as her lust took over.
And just like that, the water shut off.
“Nu-no!”
The water spout left her marehood leaving her with an empty feeling inside.
"I guess it never needs to be cleaned."
It was a reasonable assumption for Pinkie to make. She stared at the “toy” a little bit longer, studying it in curiosity.
"One more time can’t hurt, right?"
Twilight lifted her head. “Yes! Once more! Do it, Pinkie!”
The echo of hoofsteps followed until she heard the sound of Pinkie’s mattress lightly give.
"Once more."
While she was in no position to raise her rump, Twilight certainly tried. Bucking on top of her ballooned gut, she wanted to be filled further. Her wish came true as the intrusive meatstick belonging to Pinkie tunneled it’s way back in. Throwing back her head, Twilight screamed in delight.
“Yes, yes! Give it to me!"
And give Pinkie did. Pushing herself deep into Twilight once more, her cock twitching mightily inside her. The thrusting didn’t start slow this time. Pinkie went all out, sending the veritable lake of water and cum sloshing inside of Twilight. This time, Twilight resolved to enjoy the experience, rather than let her chance for climax to slip by.
“Oh Twilight, Twilight! I wish this were you! I wish It was you instead of some cheap toy!”
Pinkie’s words nearly tipped Twilight over then and there. Bouncing and waving on top of her massive belly, she threw her head back.
“It is me, Pinkie! I’m all yours! Take me!”
The churning noise returned from Pinkie’s end. The slapping of huge testicles against Pinkie’s bed filled Twilight’s ears, drawing her even closer to climax. Closing her eyes, Twilight felt deep inside her and focused her magic and that huge throbbing cock. Enveloping it with her aura, she heard a gasp from the other side of the connection.
“T,Twilight? Is that you?”
The alicorn pulsed her magic around Pinkie’s cock in reply.
“Eeeee! I can’t believe it! Are you sure you want this?”
Three more pulses told Pinkie her answer.
“I love you, Twiliiiiiiiiiiiiiaaaaaaaagh!”
Pinkie hilted herself completely into the cum balloon Twilight had become. Her mottled pink cock practically rippled with a bulge of cum. The extra force made Twilight throw her head back and howl with pleasure as Pinkie exploded inside of her.
With each thrust followed a burst of cum, pushing Twilight up another couple inches, and swelling her gut even further.
*Blort, slosh, groooan*
The water and cum inside Twilight swirled as gallons of Pinkie’s fresh jizm rushed into her. Punctuating each thrust with a mighty groan and another burst of cum, Twilight continued growing, her tongue lolling out as her belly started pushing into the sides of her bedroom. With a final cry, Pinkie’s cock pushed out one last burst of cum, moving Twilight up another six inches and leaving her with only two feet of room between her and the ceiling.
Twilight struggled to raise her head through the fog of her climax. Looking down at the vast expanse of her cum blimped belly, she could do little but wobble her hooves. Lowering her head onto the soft expanse her belly had become, she yawned and closed her eyes, allowing herself some rest.
*Thump thump thump*
A soft knocking from her bedroom door roused Twilight from her slumber. She lifted her head and watched as the door swung open.
“Oh jeez. I knew I was pent up, but I didn’t think it was this bad,” Pinkie said, squeezing into the room.
Twilight sighed. “Well, there was also that whole bathtub thing too.”
“Oh. Right.”
Pinkie climbed up on top of Twilight’s bloated cumfilled belly, dragging herself to where Twilight was stranded on top of it. “Why didn’t you tell me you liked me before?”
Twilight turned her head as she blushed. “I didn’t know how. I was sort of scared. I mean, what if you didn’t like me?”
Pinkie nuzzled up to her stranded friend. “Aww, you’re so silly. Of course I like you. Why else would you be the only one I told my secret to?”
“So, what do we do now?” Twilight asked.
Pinkie bounced in place, sending pleasurable waves in motion inside Twilight’s huge cum flooded belly. “Once you can move again, we’re gonna go on a date, of course.”
“And afterwards?”
Pinkie leaned forward, her lips close to Twilight’s. “And then, I’ll fill you back up again.”
