Just an idea that came to mind: The Mane 6 are infected by Lust, one of the 7 Deadly Sins.

The Mane 6 are infected by Lust. One of the 7 Deadly Sins. Why? They're not sure. Was this Discord's doing? Maybe. Are they going to have fun with it one way or another? Certainly. Do they all feel the effects differently? Somewhat.

For reference and to keep the story itself straight: Lust, in this version of the MLP universe, was a creation of Discord. Along with the other 6 "Deadly Sins", Lust was unleashed to wreak havoc across Equestria. When the 7 Deadly Sins were found, they were sealed away inside stones scattered across Equestria. Lust's stone was unearthed on Pinkie's rock farm while Cloudy Quartz was pregnant. Lust infected the unborn Pinkie Pie. The others have yet to be decided. Discord forgot about the Sins, much like he forgot about the Plunder Seeds from season 4.

Pinkie Pie is Lustful

Pinkie stared at herself in the mirror. She was hot. Maybe more than that. Round breasts, baby blue eyes, flawless pink skin. Sure she was a lot of pink, but that didn’t detract from her beauty at all. Here in Ponyville, she could consider herself one of the hottest. Groping her own breasts, she smiled. It wasn’t the usual broad smile she shared with her friends. It was far more predatory.

The colt laying on her bed watched her. He was young. He’d received his cutie mark recently. She’d hosted his Cutecenera. His friends and family had all gotten him great presents. This wasn’t a present. This was just Pinkie Pie. Pinkie being Pinkie as her friends would say. Many stallions joined her in her room. She was careful. Pregnancy would get in the way of parties. She couldn’t have that. A colt though was safe. He was too young. The spells all across the land prevented anypony younger than adulthood to become a parent.

“Enough standing on ceremony.” Pinkie thought to herself. In three quick strides, she crossed from the mirror to the bed. Just watching him walk to her had him at attention. She didn’t bother waiting. She didn’t have to get him ready. She was ready. She was always ready. Climbing up onto the bed, she angled herself over him on her knees. He watched her. Waiting. Anticipating. He wanted this. What colt wouldn’t? Her body was perfect. A little pudge here and there but she liked sweets. All that weight went to her tits anyway.

She dropped. He sucked in a breath and let it out all in one motion. He was hilted, completely, inside her. She bounced on him, rotating her hips every other bounce. Frequently she would hilt completely and roll her hips. He didn’t move. He couldn’t. His arms and legs were bound to the corner posts of the bed. She bounced harder on him. It was starting to hurt but it hurt in a good way. Her plush ass cushioned every blow.

Suddenly he couldn’t hold back anymore. He thrust his hips up to meet hers as best he could. The tight ropes prevented much movement, but he managed to lift his rear off of the bed. She came crashing down on his waist. The force of the impact on his hips smashed him into the bed. His balls flexed; his cock twitched inside her. She didn’t move. Didn’t even squeak. He didn’t care if he was too small for her to really feel anything. He got to do it. On his birthday.

Pinkie climbed off of him. He expected to see his own juices leaking out of her sex. She didn’t even look wet. He knew she was. His waist was drenched. He knew his fur would be matted unless he showered soon. She undid the bindings around his ankles. He tried moving his hooves to stand, thinking she was going to undo his wrists next. She was rough when she grabbed his ankles. He winced, asking what was wrong. She said nothing.

He watched as she held his hooves together, positioning them specifically just over the edge of the bed. He didn’t move. He figured she wouldn’t want him to. She climbed back onto the bed. Her rear hovered over his hooves; her face was at his crotch. He wondered if she was going to give him a blowjob. She sat down. He smiled the dopey smile of a colt giving a hoofjob to a hot mare. Pressure on his hooves.

He looked down at his body, at his legs. At her. He couldn’t see his legs past her chest. He could feel them. Something was around his hooves. Her pet. She had a pet alligator that didn’t have teeth. Was it big enough to eat a pony? Was she feeding him to her pet? Hiding the evidence of what she’d just done with a colt who had barely earned his cutie mark? She moved. Just a little, but it was enough that he could see now.

Even without being able to see, he had some inkling of what was happening. His body had been forced into a sitting position with his back still on the bed. His legs were up. Inside Pinkie Pie’s sex. She dropped, the weight of her body forcing his legs to curl inside her. His thighs disappeared into her snatch. He started to worry, trying to kick his legs. To get her off of him. He couldn’t move.

She moved forward. He was forced to bend more, now at his stomach. More of his body slipped into her folds. She was wet now. Had his dick not been enough for her? Was Pinkie Pie so odd a pony that no normal sized pony could satisfy her? She had to have something the size of an entire pony inside her for pleasure?

His hands were free. She’d removed the ropes. During his thinking, trying to figure out why she was doing what she was doing, she’d taken in more of him. Much more. He was inside her up-to his arm pits. He could smell her sex. It smelled like cotton candy. He wanted to comment on that, but something caught his eye. A glow. Right above her mound. It looked like a circle with an almost flattened out “s” in the middle of it. It was pink, though a darker pink than her own coat. The pink was outlining the black-ness of the mark.

He tried to call out, to alert her to it. It was too late. As if her sex was a mouth, it seemed to open to engulf his head. All he could see now was the world, upside down, from between her legs. His mouth and nose were no longer free. All that remained of him outside of Pinkie Pie’s predatory pussy was his eyes. Soon enough, that too was engulfed in the party ponies snatch.

Pinkie stared at herself in the mirror. The mark over her mound glowed bright pink, the colt now in her womb thrashing and fighting. He didn’t know what had just happened. Pinkie did. Pinkie knew exactly what had happened. The mark wouldn’t be satisfied with just one. Lust was never satisfied. She tried. Oh how she tried to pick from outside of Ponyville. Easier to hide the disappearance of a stranger. This colt had family here. Pinkie knew she’d see his mother tomorrow at the bakery.

There would be no sign of him. No stain of mare cum on her sheets, no lost shoes. The only evidence that he’d ever even existed at all disappeared into her body. The last few drops of cum he ejaculated as he was sealed away. A “panic jizz”. It had happened before. Caramel. He’d been an accident. Just a quicky, nothing special. He knew what it was. Pinkie didn’t want a relationship with him. Not really.

She sat on his face. Both of them had thoroughly enjoyed it. Up until he didn’t. Because his head was inside her snatch. Completely. And the rest of him was being drawn in. He may have been bigger than this colt, but he’d been quicker. Within moments, Caramel was sealed away inside Pinkie. He was melted down just as quickly. Not even a stain on her sheets, just a panicked jizz that splashed her in the chest and face.

She figured it was because as long as it was a pussy, stallions didn’t care what was happening to them. Whether they were being eaten alive or sucked dry.

Absentmindedly fingering the mark on her belly, Pinkie lay on her back on her bed. She barely remembered when it had shown up. Around the same time as her cutie mark? Maybe. Unlike her cutie mark, this one came and went. Every couple of years she had to “satisfy it”. Her first had been that colt that was sweet on Limestone. Lime hadn’t shown any interest in him, so Pinkie took over. He disappeared. Nopony asked questions. This colt had been her fifteen hundred and seventy sixth. She kept count. Names she didn’t remember. How many there were she did.

Did she feel like a slut because of how many ponies had disappeared into her snatch, never to be seen again? Maybe just a little. Did she feel like a monster because of it? Not so much anymore. It was just routine for her now. She didn’t have to do it every day, just every couple of years. Now that she knew how to handle it. When it had first appeared, she didn’t know. She took a new colt every other day. That’s why her number was so high. It wasn’t until after she’d officially moved to Ponyville that she’d learned to manage.

No pony knew about what she did. Not really. Rainbow Dash had her suspicions, but Rainbow had also been on the receiving end of Pinkie’s predatory pussy. When they’d first met, Pinkie was craving. She was hungry. Rainbow was always ready for a challenge. Pinkie challenged the blue pegasus to stick her head into a multitude of different soft, squishy things. The last soft squishy thing had been Pinkie’s own snatch. Rainbow’s head went in. Followed by her shoulders. Then her wings.

Then Rainbow had kicked off of the ground. Pinkie’s head collided with a wall. Rainbow slipped in more then bounced out. She didn’t talk to Pinkie for a month afterwards. She’d been the first to escape. She’d also been the last for a long while. They eventually became friends, but Rainbow was always very cautious about being near Pinkie’s behind. She still didn’t quite know what had happened that day, and Pinkie kept quiet about it. They were friends now. No reason to bring it up.

Pinkie continued to stare at her ceiling, stroking the mark gently. No pony even knew it existed. Not even the Princesses. “I should tell them…” Pinkie’s only thought before she drifted off to sleep. The mark was satisfied for now. Lust had been sated. With a "meal" this size, Pinkie was safe for another couple of months.

The Lust is Spreading

Author's Note

So this chapter has some unwilling in it, as well as some slight "underage". Far as I know, once a pony has their cutie mark in MLP, they're an adult or at LEAST a teenager. Also marks one of the longer chapters in this story, and one of the ones with the least ammount of dialogue. Was trying to make the naughty "kink" scenes take precedence over the dialogue.

The Lust is Spreading

After her… encounter with Pinkie Pie’s rear end, Rainbow hadn’t felt good. Not in a “I almost got eaten by Pinkie’s ass” sort of way. In a “sick to her stomach but not because of nearly being eaten by a literal ass hole” sort of way. She felt sluggish. Flying to Wonderbolts practice had been a chore. Getting changed into her flight suit had been nearly impossible. Just being around other ponies had made even moving properly hard to do.

Flight practice was another thing entirely. She was slower. Not on purpose, as far as she was aware. But everypony was flying faster than her. She found herself staring, constantly, at the butts ahead of her. Flitter, Fleetfoot, Soarin, Misty, Dusk, Spitfire. All of them were flying ahead of her. It wasn’t until a part of their routine for the next show that Spitfire fell back to fly beside her that they noticed.

The routine in question required Spitfire and Rainbow to fly side by side at a speed that would push Rainbow into a Sonic Rainboom, which would ignite some pyrotechnics in both of their suits. They were safe, of course, and were supposed to burn the suits off. Under their typical flight suits were ones designed to bring the attention of the crowd to them. But Rainbow wasn’t flying that fast. Spitfire called a break, and the group flew back to the landing strip.

“What’s going on with you Crash. You’re flying slow today.” Spitfire said and Misty scurried over. Ever the worrisome filly, Misty reminded her of a slightly braver Fluttershy.

“You’re not sick are you? Did you eat some bad rations last night? Do you need to take some medicine? I have some anti-acids here somewhere.” The “motherly” mare said, fiddling with her bag at one of the benches.

“I’m fine Misty. At least… I think so. Captain, can we talk privately? It’s kind of an embarrassing story.” Rainbow said and Spitfire blinked. Rainbow wasn’t one to hide anything, so if she wanted to talk in private, they’d talk in private. Leading Rainbow away from the group, taking to the air to head towards the office buildings, the two of them flew into Spitfire’s office through the window.

Once they were seated, Spitfire closed the window before zipping over to the door and latching it. “Alright Dash. You are the most braggadocio pony I know. You like the spotlight. What’s eatin’ ya?”

“Funny you should say it like that. You remember my friends, specifically my pink friend, Pinkie Pie?”

“I remember she makes those killer pies you share with us.”

“Well… something’s wrong. Down in Ponyville, I mean. With Pinkie Pie. Last week, I think it was last week anyway. I’ve been distracted… last week she almost ate me.”

“Ok… this seems like something you should bring up to Princess…”

“With her ass.”

Spitfire stopped mid-sentence; Princess Twilight’s name frozen on her lips. “Come again?”

“Pinkie almost ate me with her ass. Well not her ass. I went to check on her because she’d been cooped up in her house all day and when I went inside there was this smell… not a bad smell but it made me want to not really think. I guess it’s been a while since this happened… and it wasn’t her ass it was… it was her pussy. I don’t really remember what exactly happened. She challenged me to something, and I did it, but when I realized something was wrong I tried to get away, and I did, but now I can’t stop thinking about it and I can’t talk to Twilight or anypony else about it, but we work together and…” Dash was stopped when Spitfire raised a wing.

“Crash… Rainbow. I really think you should talk to Princess Twilight about it. If it’s something that’s bothering you this badly, you need your friends to help.”

“It’s not that it’s bothering me. I can’t get it out of my head.”

“Get what out of your head?”

“How it felt. For her. I want to know how it felt for Pinkie when I was inside her.” The silence following Rainbow’s admission was deafening. Eventually, it was broken by Spitfire laughing.

“I hate to break it to you Crash… but I don’t think you’re stretchy enough for that sort of thing.” Spitfire said between bursts of laughter.

“Yeah. I know, but I want to try!” Rainbow said, her voice just barely under an actual shout.

“Tell ya what Crash…” Spitfire said as she eventually caught her breath. “We’ll do this. You go on leave; we’ll say about a week. You’re not getting suspended or any sort of punishment. We have a show in a month, and we need our best flier at her absolute best. Talk to Princess Twilight about what happened when you’re comfortable enough to talk to her. When you’re back, with your head clear, we’ll do the show and then figure out where to go from there.

“If your head isn’t in the right place, we’ll put you on temporary suspension.” Spitfire held up a hoof before Rainbow could argue. “Temporary suspension. With pay. You’ll still be a Wonderbolt, you’ll get to come back whenever you want. But you need to get your thoughts straightened out. Maybe stay with that Pegasus friend of yours. Fluttershy, I think you said her name was. She seemed like the kind of pony that would understand.”

Rainbow stared at Spitfire for a long time before finally nodding. Taking off her Wonderbolt’s badge, she set it on Spitfire’s desk. She wasn’t fired. She was being put on leave. Mental health leave. That was it. She just needed to get in the right head space. Fluttershy could help. Of course she could help. Fluttershy helped some of her critters birth their young if they were having problems. Talking to her best friend about sex wouldn’t be a problem. It’s just filly talk. It’s not that strange.

She didn’t even realize she’d flown to Fluttershy’s cottage until she nearly bashed her nose into the door. Raising her hoof to knock, she paused. It was Fluttershy. The timidest mare she’d ever known. Sure, helping critters with tough births was one thing. But they’d never even mentioned dates. Talking about sex was just… it wasn’t something they could do. Right?

Knocking on the door, Rainbow surprised herself. She hadn’t even known she was moving to knock. She was so lost in her thoughts. She didn’t even notice when Fluttershy opened the door. She didn’t feel herself talking. She didn’t hear her own words. It was like something had taken over her body. She walked into Fluttershy’s cottage and sat on the couch. Unconsciously she took the tea Fluttershy offered her. They talked well into the night. About what, Rainbow had no idea.

It was dark by the time they finished talking. Fluttershy insisted Rainbow stay the night rather than fly home. Mentally, Rainbow insisted she was fine. Physically, she must have said yes because the two of them were walking up to Fluttershy’s bedroom. They were friends. Of course they’d sleep in the same bed. Comfort was Fluttershy’s number one concern. They got in bed, under the covers, and Rainbow watched as her first friend since Gilda drifted off to sleep.

Her body was on autopilot. She stood, the covers simply sliding off of the bed, as she moved to stand over Fluttershy. She thought she heard tapping at the door. Probably Angel Bunny, sensing something was going on. He’d never get into the room. Rainbow knew it. Angel wasn’t allowed in Fluttershy’s room. He was far too protective of her, and she needed some semblance of privacy. Rainbow’s wings flared out to her sides. And out. And out. They continued to grow until they were large enough to wrap around the entire bed.

No. It wasn’t her wings. Just her feathers. They had elongated and were much thicker. Almost like tendrils. She could feel them angling down towards Fluttershy. As they started to wrap around her, Rainbow fought. She had to get control of her body again. Whatever was controlling her, changing her, was going to do something to Fluttershy. Something that Rainbow just couldn’t allow.

A sudden intrusion in her body made her freeze. That was much larger than her toy. Looking behind her, she froze. At least mentally. Her wings, the tendril like feathers, were pushing Fluttershy into the prismatic mare’s cunt. Worse still, her cunt was pulling the timid mare in head first. Fluttershy was awake. Rainbow could feel that. She was terrified. They both were. Rainbow had to get control.

A contraction sucked Fluttershy in up to her waist. Rainbow felt her body stretch around her friend. She could feel the immense pleasure. This wasn’t right. This body was hers. She wasn’t some monster that would devour her friends. Another contraction and Fluttershy’s hips were the only things that prevented further movement. Now she was stuck. And it could hurt her.

Rainbow growled at herself and forced her wings to return to normal. She wasn’t sure how she knew she could do that, but she had to do it. For Fluttershy. Her wings slowly turned back from elongated tendril like things to their natural feathery softness. Fluttershy was still mostly inside Rainbow’s cunt. Rainbow blushed, unable to really hide how good this felt anymore.

Fluttershy would need to wash her sheets. And her entire bed. Maybe just get a new bed. Rainbow gasped as her body contracted again. Inward pressure, trying to pull Fluttershy in. The pressure against her cunt lips was incredible. But she had to stop. She had to save her friend from whatever her body was doing. Standing on her hind legs, Rainbow pressed against her belly with her front hooves.

It took very little pressure and Fluttershy spilled out of Rainbow’s sex with a wet flop. Gasping for breath, the two of them looked at each other. “I’m sorry.” Rainbow said before disappearing out of the open window in a blur of rainbows and blue feathers. Something was wrong with her. She knew it. Even as she swooped down on an earth pony colt going to Twilight’s school of friendship.

He was old enough to have his cutie mark. An adult, just going to the school to learn about being friends with the other races. Rainbow recognized him from one of her own classes. None of that mattered right now. Right now, he was just food for her hungry cunt. She hid on a cloud high above Ponyville as the colt struggled. Rainbow’s cunt pulsed and squeezed, pulling him in. Unlike Fluttershy, he didn’t even make a bulge. As soon as his hind legs disappeared, Rainbow felt better. She’d just eaten someone with her pussy… and it made her feel better.

“I have to talk to Twilight…”
