Fluttershy's Biggest Secret

Fluttershy and Trixie were asleep on the former mare’s bed, wrapping each other in their forelegs for comfort and perhaps a level of love they have established after the previous day’s activities. They unconsciously nuzzled each other and quietly mumbled words of affection that came from their pleasant dreams relating to their love, or rather, their ‘love’.

The yellow mare suddenly stirred, breaking out of her sexual reverie and noticing the sapphire pony she was hugging, smelling her scent, feeling her soft coat, and hearing her light breathing and occasional murmurs of lust. The words she heard made her blush harder than her dreams already made her.

She pulled away from the unicorn, untangling their legs and sliding off her bed. Fluttershy stood at the side of it for a moment, looking at her friend, before she noticed her whimpers.

“N-no... you can’t abandon Trixie... nopony else will help her...” Trixie cried quietly, moving her forelegs around, trying to find her lover.

The pegasus sympathized with her, remembering what she said about her time since her usage of the Alicorn Amulet. She moved a pillow to in front of her friend in an attempt to curb her sadness. She then heard the whimpers die down and be replaced with some light moans, lustful words, and a few mentions of punishment she blushed at after she got over how cute Trixie was.

Fluttershy next left the room and went downstairs to the kitchen to prepare food for the animals, finding that she was rather low on some of her food items. She remembered that she wanted to go get some more when she was out with Rarity yesterday, but that didn’t happen, so she had to get more today.

She sighed and grabbed the list she had put on the pantry two days previously and her saddlebags in the main room before she opened the door.

“Hi, Flutters!”

Fluttershy shrieked and jumped backwards, landing on her haunches a couple meters away, her forelegs covering her face. She sat there for a moment, shivering in fear, before she noticed the light giggled coming from the open door. She slowly moved one of her hooves to the side to see who it was coming from. “P-Pinkie?”

“Yep, that’s me!” Pinkie said, walking through the open door and closing it. “Are you alright? I didn’t mean to scare you that much,” She asked, her mane slightly drooping.

The pegasus breathed deeply and got back to her hooves before responding, “Um, yes... I-I just wasn’t expecting you...”

“I know! But I’m here because I actually wanted to talk to you about something.” The pink pony replied.

“Oh, uhm... about what?”

“About your secret,” Pinkie said very ominously.

Fluttershy suddenly became rather worried that her energetic friend knew about her stallionhood, asking, “My-my secret?”

“Yeah, your secret!” The party mare replied, back to her enthusiastic self. “Because I was talking to Twilight yesterday and she mentioned she visited you and when I tried to get her talk more about it she got kind of awkward, like she’s trying to hide something from me, but she did tell me that you were busy with somepony, but she didn’t tell me who, so I came here to talk to you about it!” She rambled, slightly leaning forward as if to accuse her friend.

“Oh...” The pegasus sighed out of slight relief, still somewhat nervous about having to reveal some part of her relationship with Trixie. “Umm...” She hesitated, going quiet when she heard light hoof-steps on the stairs behind her.

Pinkie stared intently at Trixie as she slowly descended the stairs, slightly shivering out of fear. When she reached the base of the stairs, she stopped and Fluttershy looked over at her with a face that told her that she knew what she needed to do.

“Umm, Pinkie...” She started, “T-Trixie is sorry for everything... For... humiliating your friends, for nearly enslaving everypony here, and f-for...” She trailed off as she saw the pink pony approaching her, making her crouch down and whimper in fear. Her fear was slowly replaced by confusion as Pinkie sniffed her deeply, leaning down to put her muzzle into Trixie’s mane and sniffing again before pulling back to look at her suspiciously.

“...Pinkie?” Fluttershy asked, also quite confused at the interaction happening before her.

The mentioned mare to look at her and abruptly said, “I never knew you had a penis!”

The yellow pony stood still at the sudden mention of her stallionhood, realizing that Pinkie was smelling the cum that she didn’t entirely clean out of Trixie, before she blushed heavily and turned her head away out of embarrassment, finally responding, “Um... well, I-” She started, cutting herself off when she looked back in front of her, seeing the pink earth pony right before her.

“We didn’t need to know about it,” Pinkie finished, a little disappointed in realization before she brightened up with a thought, “but now that we do...” She licked her lips seductively, causing her friend to blush even harder. The energetic pony then pounced on her, pinning her back to the floor, their lips locked, while she tried to force her way into the pegasus’ mouth.

Fluttershy’s surprise eventually died down enough for her to allow her friend’s entrance, which she took full advantage of, licking and slapping her tongue around the inside of the yellow mare’s mouth, making her moan from the unusual sensations.

Trixie watched the fierce make out session from the side, her sex becoming wet as she started lightly panting. She sat down and placed one of her hooves on her pussy, slowly rubbing it while she Fluttershy’s cock and balls started to come out from her groin. The shaft pressing between them got Pinkie’s attention, causing her to pull away and stare at it.

“Mmmm... there it is,” The party mare said, moving down to put her muzzle in front of the cock in question. She next stuck her tongue out and touched it to the tip and licked it down to the base, sliding her tongue around the still-growing shaft before she started slurping up and down it, lathering it in saliva. She placed her two front hooves on the massive, plump balls below it, caressing and lightly pressing into them, making the pegasus they belonged to moan quietly.

Pinkie then released her grasp on her friend’s huge stallionhood and moved her body up to mount it, but stopping when she heard a comment from the side.

“Um, Trixie doesn’t think you should do that here...” Trixie stated while still lightly masturbating, adding, “It would be really hard to clean if you did...”

“Yeah, but it’ll all be in me when we’re done!” The pink pony said as she turned her head to face the unicorn.

“Maybe, but,” The sapphire mare started panting a little harder at the mental image of a heavily cumflated Pinkie Pie but continued, “there’s going to be so much, you probably won’t even be conscious when she’s done...”

“Oh...” The pink mare sighed, realizing the implications of what Trixie just said. “Well, in that case...” She pulled Fluttershy to her hooves and up the stairs, her balls slapping against her hind legs and lightly scraping the steps as she was nearly dragged up them before they went into the bathroom. Trixie hastily followed them, occasionally slipping on her juice-coated hoof.

Immediately when they entered the bathroom, Pinkie threw her well-endowed friend to the floor, her now erect cock standing straight up, and pounced on her, pressing the shaft between them while engaging in another messy kiss. The party pony then moved her hindquarters up while keeping their lips locked, managing to fit the huge cock perpendicularly between them, squishing its tip into her bright pink pussy.

Trixie sat by the door, her sex beginning to froth at the scene in front of her. She quickly realized, though, that the shaft wasn’t going to penetrate like that without assistance, so she focused her magic to hold it steady and force the lips of the cunt it was trying to enter open. The stallionhood finally began making headway because of this, the sapphire unicorn releasing it when she saw it had sufficiently penetrated Pinkie’s pussy.

The pink and yellow mares separated with a deep moan as Fluttershy’s shaft went into her friend down to the medial ring. Pinkie then started to move up and down the cock, slathering it with her juices and taking more of it with each thrust, moaning louder with the deeper in her it was.

Trixie approached them from behind, lowering her head to keep the massive canary-colored ballsack in the center of her vision. She stopped right before it, leaning it to lick it as Pinkie’s tail flailed right above her head. The lick quickly evolved into Trixie shoving her muzzle between the balls, smelling and tasting the heavy musk on them and hearing the lewd smacking right above her muzzle as the party mare began making contact with the base of Fluttershy’s cock.

The blue mare lifted her backside up and began masturbating again, forcefully squishing and rubbing her labia with one of her hooves, the other being used to press the balls she was sniffing further around her muzzle, completely enveloping her nostrils with that intoxicating scent.

Pinkie, meanwhile, was riding her yellow friend’s massive cock with increasing speed, covering more of its length with each thrust until she was going along the entire thing, up to the tip and down to the base, about once per second. She squealed at a nearly inaudible pitch as she came, squirting her juices around the shaft she was stuffing and re-stuffing her pussy with.

Fluttershy had her head craned backwards and tongue lolled out in pleasure by the time her entire length was being repeatedly coated and sprayed with Pinkie’s liquids. After a few seconds, she started to scream and her cock began to throb, ejecting huge ropes of cum into the pink mare’s pussy. A lot of the cum overflowed from there, however, and gushed down the throbbing shaft and onto Trixie’s head.

The unicorn noticed the stickiness in her mane and broke out of her reverie, pulling her muzzle out from between those huge, heavily musky balls. She touched her tongue to the cum flowing down the stallionhood above her and savoured its taste, pushing over the knife-edge of orgasm, spraying her own juices over her hoof as she licked up and around the shaft, taking in as much cum as she could before swallowing.

After Trixie finished her orgasm, she reached up with her front hooves to press Pinkie’s backside all the way onto the spewing cock and keep it there, forcing it to fill up her womb. The pink mare’s orgasm, which was dying down, surged back to full strength, killing her voice and making her tongue loll out of her mouth with incomprehensible pleasure as her belly began to expand.

Fluttershy’s cumming started to slow down, her screaming following suit as she inflated her pink friend’s belly to nearly be able to fit another pony inside of it. The sapphire pony below her decided, though, that that wasn’t big enough. She stuck her muzzle into the yellow mare’s ballsack again, pressing deep into it and squishing it against her face with her hooves.

The pegasus groaned out of pleasure, her still fully erect cock shoved into her well-padded friend and her balls being squeezed and sniffed so forcefully. It was so pleasurable it only took a couple of minutes for her to cum again, this time not even phasing the unicorn stuffing her muzzle into the productive balls before her, as her enthrallment to their scent and feeling completely dulled all of her other senses.

Pinkie started cumming again as she continued to inflate, her juices gushing out around the cock stuffed into her cunt. Her belly soon was the size of two ponies pressed together, and was still growing rather quickly because Fluttershy’s orgasm was being perpetuated by Trixie’s incessant squishing, sniffing, and licking.

The minutes flew by as the indescribable pleasure they all were in held, the pegasus cumming with no end in sight, pumping the party mare bigger and fuller with her seed, making her into no more than a cum-filled balloon with legs and a head.

The inflation only began to cease when the constantly cumming pegasus was finally completely overcome by pleasure and lost consciousness. Her stallionhood spurted a few more times into the pink mare it was shoved into, inflating her to nearly the volume of eight whole ponies, before it started to soften and slip out of her friend’s pink pussy.

Trixie broke her reverie and pulled her muzzle out from between the musky balls she was sniffing for the past Celestia-knows-how-long when she noticed the yellow mare above her stopped cumming. She then saw Fluttershy’s stallionhood retreat back into her, rendering her gender ambiguous once more. She next took notice of Pinkie, attempting to lay on her massive cumflated belly from her upright position.

The unicorn gasped in shock when she saw how large the pink pony had become, before sighing in realization, telling herself, “This is going to take a while to clean up...”
