Fluttershy’s wings twitched slightly as she worked. She was aware of the movement but unable to control it, being part of her not insignificant gag reflex. She suppressed a cough as she tried to force more of Macintosh’s large penis down her throat. She was kneeling in front of him on the floor, while he sat on his bed, his pelvis eye level with Fluttershy. She was an inch or so past the head of his penis (a new record for her), but her tears were stinging her eyes and a coughing fit soon rendered her unable to breathe. A powerful cough caught in her throat, and she yanked her mouth off of the large member, coughing and gasping for air.

She tried to wipe away the tears streaming from her eyes, but they wouldn’t stop flowing. She heard Big Mac lean forward from his sitting position on the edge of his bed, and his large hand found its way to Fluttershy’s shoulder, giving her a comforting squeeze. As she slowly caught her breath and the flow of tears started to subside, she tried to gasp out an apology.

Macintosh simply grabbed her by the chin and kissed her.


Fluttershy sighed and absentmindedly poked at a slice of cake with her fork. She was sitting at a table outside of Sugarcube Corner, waiting for Pinkie Pie’s shift to end so they could talk. Fluttershy snapped into startled attention as Pinkie suddenly plopped into the chair across from her. She put her drink down onto the table (it was some sort of coffee and cream concoction with an unhealthy amount of caramel and whipped cream) and struggled somewhat with her name tag.

“Sorry about that ‘Shy, I had to finish up a birthday cake before I could punch out.” She managed to pluck the tag from her bright yellow t-shirt and chucked it into her pink purse. “So what’s up? You don’t look so hot.”

“Oh… it’s nothing really.” Fluttershy was suddenly too embarrassed to tell Pinkie about what was troubling her. The thought of telling somepony that she couldn’t please her boyfriend, even if it was Pinkie… the thought alone was mortifying! “I just… you know…” She stuffed a piece of cake in her mouth to avoid talking.

“Problems in bed?”

Fluttershy choked on the soft cake for a moment before recovering. Gasping for air she stammered “H-h-how d-did you kn-know?”

Pinkie leaned back in her chair, triumphant. “Lucky guess. Besides, Mac and I used to date, so I know the… size of the problem you’re dealing with.”

“Oh Pinkie…” Fluttershy felt the familiar tears spring up in her eyes. “I can’t please him! He says he doesn’t care but it just isn’t fair! He always makes me feel so good, but I can’t do anything for him! What do I doooo?”

“Dump him.” Pinkie’s tone was flat. “Let him remember that he’s missing all this.” She squeezed her pudgy stomach and gave it a wiggle. When she saw the tears flowing down Fluttershy’s face, she sprung to her feet and brought the girl in for a tight hug. “Only joking! Only joking!”

They stayed like this for a while, Pinkie stroking Fluttershy’s long hair, with Fluttershy’s face buried in Pinkie’s chest, crying softly. Fluttershy pulled away after a few minutes, drying her eyes. She saw the tear stains on Pinkie’s shirt and gasped.

“Oh Pinkie! I’m so sorry! Your shirt-“

Pishaw, it’ll come right out.” She brushed off Fluttershy’s concerns with a nonchalant wave. She gave Fluttershy a quick kiss on the cheek before turning towards Sugarcube Corner. “I might have an idea that could help you out. But first, I’m gonna need to make a few phone calls…”


Twilight bit onto her pillow to prevent her screams from being heard outside of the library. She could feel her lover’s tongue exploring the folds of her vagina, reaching deeply into the place few ponies had ever been, sending waves of pleasure up her spine in electric jolts. Her hips bucked wildly, as if she was trying to escape the pleasure between her legs. Of course, Twilight wanted nothing of the sort. She would be happy to stay like this forever if she could. She felt her lover’s hand reach under Twilight’s pillow in order to find her breasts. The probing hand found its target, and gave Twilight’s right nipple a firm pinch, eliciting squeals of delight from the purple unicorn.

Twilight looked over the pillow at her partner and locked eyes. Twilight could feel her orgasm building up inside of her, like a ball of fire below her stomach, slowly spreading out to reach every part of her body. Twilight reached between her legs and grasped the other unicorn’s horn roughly, sending a sudden jolt through her lover’s body. Twilight used her newfound leverage to push her partner’s face deeper into her crotch, forcing her orgasm to arrive as quickly as possible. Twilight’s hips raised half a foot off the bed as her orgasm took over her body. Goosebumps spread over her skin, and her horn shot feeble bursts of magic sparks into the darkened bedroom, and Twilight tried not to scream, knowing that she would fail as usual.

Twilight flopped heavily onto her bed once her orgasm released her from its powerful grip. She threw the pillow aside, trying to ignore the highly visible teeth marks she left in the fabric. She gasped for air and mopped the sweat from her brow and from between her breasts. She realized that her toes had been curled up into tight fists for the past few minutes, and slowly stretched them out once more. Her partner crawled up Twilight’s body, and lay on top of her when she reached eye level. The sweat from their purple and light blue bodies mixed together on their skin and on the bed as they shared a soft, loving kiss that seemed to last hours.

“So…” the blue unicorn gasped, breaking the kiss, “did Trixie give you a great and powerful orgasm as usual?”

Twilight chuckled and playfully pinched Trixie’s nose. “Don’t be such a dork.”

“A dork? This, coming from you? The princess of all dorks?”

“Laugh it up, Lulamoon. Find another tree to live in.” Twilight smiled once again and kissed her lover.

The intimacy was broken by Twilight’s phone, ringing in a drawer of the nearby nightstand. Twilight broke the kiss and groped blindly for the drawer. Trixie tried to swat away her hand. “Just ignore it, sweetie.”

“I can’t, that’s Pinkie’s ringtone. If I ignore it she’ll just keep calling me until I pick up.”

“So turn your phone off.”

“She’ll climb onto the balcony.” The tone of her voice told Trixe that she was dead serious.

“Ugh, fine.” Trixie rolled out of bed and padded her way towards the bathroom. “I’ll be in the shower. Feel free to join me.” She closed the door behind her, and Twilight heard the hiss of running water.

She shook the images of a soaking wet Trixie from her mind and answered the call before it went to voicemail. “Hello?”

“Twilie! It’s Pinkie!”

“Hey Pinkie, it’s not actually a great time to talk…” The thoughts of water cascading down blue skin wouldn’t leave the forefront of her thoughts.

“You and Trixie can bang later! This is urgent!”

Twilight was dumbstruck. She had tried to keep the nature of her relationship with Trixie a private matter. It’s not that she was embarrassed, she was simply a private person, and her sex life fell heavily into the ‘noponies business’ category of privacy. “How… how did you-“

“How did I know you and Trixie are pussy pals? Geeze Twilight, you make it super obvious. Everypony knows!”

This news was… somewhat disturbing, to say the least. But it would have to wait for later. Pinching the bridge of her nose, Twilight changed the subject. “What’s so urgent that you had to call me about?”

“Fluttershy can’t suck dick!”

Twilight had to resist the urge to throw the phone at the wall. “And why… is that… urgent?”

“She’s been dating Big Mac for like a year now and she can’t make him cum! I saw her today and she was all torn up about it! I hate seeing my friends sad! Please Twilight, you have to help!”

Twilight sighed, but she knew she couldn’t avoid the situation. She may not see eye-to-eye with Pinkie all the time, but the trait they shared was to strongly care for their friends. If one of the girls was sad, neither Pinkie nor Twilight could rest until the situation was resolved. “Fine, Pinkie. What should I do?”

“Meet me tomorrow at Sugarcube Corner. Noon. Oh, bring Trixie.” The line went dead.

Twilight tossed her cell phone onto the bed and made her way into the bathroom. She pulled the shower curtains aside to find Trixie lathering her breasts with soap in the tub. Trixie grinned at the sudden appearance of her girlfriend and scooted aside to let the purple unicorn in.

“Pinkie wants us to meet her at Sugarcube Corner tomorrow.  Fluttershy is having boy problems.” Twilight grabbed the soap from Trixie’s hand and started to soap up her toned legs.

“Us? Me too?” Twilight nodded in response. “Why me?”

“No clue. Whatever, I have something else on my mind right now.”

“Like wha-“ Trixie was cut off when her tail was suddenly raised high above her head by Twilight’s levitation magic.

Twilight leaned in and kissed her girlfriend softly on the lips. “Bend over, Lulamoon.”


Rainbow Dash bit her lower lip as the strap-on eased itself into her tight anus. She was bent over Applejack’s bed, the owner of which was penetrating her with a brand-new, 8-inch ribbed strap-on dildo. Dash felt the first ridge of the phallus slowly stretch her anus open wider than it had ever been. She gasped in pain as the thought of the toy tearing her apart ran through her mind. She gasped in pure ecstasy as it suddenly slipped past the widest point, quickly popping the rest of the way into her pink hole.

“You gonna be alright, Dash? There’s a bunch more ridges to go.” Applejack always sounded worried when Dash made her perform anal.

“Just shut up and fuck me,” she groaned. “And use more lube.”

Applejack rolled her eyes, but moved to comply. She reached to her side and pulled a half-empty bottle of lubricant from the top of her nightstand, uncapped the bottle, and squeezed a healthy dose of lube onto the dildo. She tossed the bottle aside and rubbed the glop of lube along the shaft of the dildo until it was evenly spread.

Dash was getting impatient at this point. “Come on, AJ.” She wiggled her ass slightly farther down the shaft of the dildo. “Fucking fuck me already.”

AJ frowned and gave her hips a quick thrust, sending an entire ridge of the dildo into Dash’s bowels, making the small Pegasus shriek and clench the bed sheets in her fists. AJ leaned in close to her girlfriend’s ear. “What’s the matter, darling?” she whispered coyly, “I thought you wanted me to fuck your tight little asshole.”

“I’m gonna kill you.”

AJ chuckled and quickly pushed another inch into Dash’s ass. Dash once again shrieked, and fell face first into her pillow. A muffled groan of pleasure told AJ to keep going. She complied. She pushed forward again, this time more slowly, watching as another ridge expanded Dash’s sphincter before disappearing inside of her. Then another. And another. Soon enough she was buried to the hilt in Dash’s tight ass. Dash didn’t seem to even notice at this point; she hadn’t moved in some time, keeping her face buried in her pillow.

AJ gave the Pegasus an experimental spank, and recoiled in shock as Dash’s head snapped backwards. Her eyes where almost rolled into the back of her head and her tongue was lolling. Her normally light blue face was flushed a deep red, and she was panting heavily. “Um… Dash?” AJ was worried that something had gone wrong. “Honey? You okay?”

“AJ… I…” Dash’s panting was making it difficult for her to speak. “I… I love you.”

AJ was momentarily stunned. She looked away and her orange cheeks turned beet red. “I uh… ahem. I love you too.” This seemed like an awkward situation to be talking like this. She snapped back to attention when she was almost clocked in the nose by Dash’s foot swinging past her face. She was rotating her body so that she was now laying on her back. She then put the palm of her hand flat against Applejack’s chest and pushed, tipping the girl backwards.

“Dash, what’re you doing?” AJ’s head hit the mattress with a satisfying flop.

Dash was now straddling Applejack’s hips, the dildo still buried inside of her. “This time… oh fuck me this thing feels awesome… this time I wanna be on top.” She grinned. “This time I’m the cowgirl.” And with that she started to raise herself off of AJ, freeing the dildo from inside of her. She gasped as she felt the ridges pass through her, almost feeling better than when they entered her. She stopped after a few inches and pushed herself back down more quickly. “Oh god damn. This is the best invention in all of history.”

AJ pulled herself upright so she was eye level with Dash. She pulled the Pegasus into a tight embrace and began to gently thrust her hips. It took a few false starts, but soon they were in rhythm. Their hips, now working in tandem, began moving faster and faster, pushing onto each other before quickly pulling away. Dash’s gasps became moans. The moans became screams. The screams were silenced by Applejack pressing her lips to Dash’s, their tongues intertwining. Dash began to flap her wings to match the rhythm of the thrusts, adding more force to the already powerful fucking she was receiving. The sound of Applejack’s hips slapping against Rainbow Dash’s buttocks and their muffled moans mixed with the wet, slick sound of the lube doing its job were the only sounds to be heard throughout the empty farmhouse.

Their lips separated and Dash gasped out a plea. “Keep going. I’m… I’m gonna cum.”

AJ redoubled her efforts. “Me too,” she said through gritted teeth.

AJ thrust furiously into Dash, making the small girl go limp with the force of the blows. Their gasps rose into a single scream at the same moment as a furious orgasm wracked both of their bodies. They held each other tightly as they felt the adrenaline slow and their hearts began to pound.


Applejack was drying her hair with a towel when she heard the bing of a text message received. She picked up the phone and read the strange message from Pinkie Pie.

Dash walked into the room, likewise towling herself off. “What’s up?”

AJ frowned. “According to Pinkie, we all need to meet up tomorrow at Sugarcube Corner for an urgent meeting about… my brother’s penis.”

“Oh.” There was a moment of silence as Dash continued to dry off. “Wait, what?


Rarity received a similar message from Pinkie while she was putting the final touches on a fancy hat. She wasn’t having sex or anything. Sorry.

Sweetie Belle was masturbating in her room, though. But she’s not part of this story, so let’s drop it.


The next day at noon, the girls met up at Sugarcube Corner, wondering just what the hell Pinkie had in store for them. At noon exactly, Pinkie rushed down the stairs to the bistro and waved her friends up to her room.

They arranged themselves silently in Pinkie’s frilly, mostly pink room. Nobody spoke up. Trixie absentmindedly grasped Twilight’s hand, feeling nervous as she was in a near stranger’s room.

Applejack broke the silence. “Alright Pinkie, what in tarnation-“

“We’re gonna have a rainbow party.” Both Pinkie’s tone and expression were dead serious.

Rarity seemed to be the only one who knew what this meant, and stifled a gasp. “Um… darling…” she started nervously, “when you say ‘rainbow party,‘ do you mean-”

“We’re all gonna wear different color lipstick while we suck off Big Mac so Fluttershy can learn how to suck a big cock like Mac’s in order to save their relationship, yes.”

Silence hit the room like a ton of bricks. The girls glanced around nervously, hoping this would prove to be some sort of joke. The punchline didn’t seem like it was forthcoming.
