He might get a piece of his own sister, if she doesn't break him before that.

He Maybe Should've Thought About This

For Fluttershy, heat season was the absolute worst. Every year, it was doing everything to deal with that burning itch just short of having sex with a stallion.

This season had been particularly bad, as Zecora had sold the last relief potion just before she arrived. It would be another day before she had her stock refilled. It was a day she wasn’t sure she’d get through.

The ache was excruciating, and it had left her in a terrible mood. She was irritable, grouchy, and was simply done with just about everything. This was exactly why the animals had vacated her cottage, which meant she was lonely on top of all of that. All she had was the thought of the one time she had sex during a previous heat season. She had to admit it had been a wonderful time, right until she came back to her senses and realized just who it was she had sex with.

“Hey sis!” a stallion sing-songed as he waltzed in through the front door.

“Ugh, not now,” Fluttershy muttered. This was the worst time for Zephyr to drop by, especially since the last time he came in like this during heat season, he ended up rutting her.

“Ooh, I know that scent. Yeah, Rainbow Dash is in heat too. I offered to give her some much needed relief, but that mare just loves playing hard to get,” Zephyr said as he continued on in, regardless of how annoyed Fluttershy was quickly becoming. He even had the gall to set himself right beside her too.

“What are you doing here?” Fluttershy asked, almost snarling.

“Oh dear, looks like somepony else needs some sweet relief. Well, I was here to just visit, but… since you seem to be in need… I suppose I could give you some of my brotherly love. I remember how much you enjoyed it last time,” Zephyr said.

“I decked you afterwards,” Fluttershy replied.

“Pfft, minor detail at best. I know you want relief, and here I am willing to give it to you. All you have to do-” Zephyr shifted himself to mount her sister, his hardening shaft rubbing between her cheeks, “-is say yes.”

Fluttershy wanted to hit Zephyr so hard right now, but at the same time, she wanted relief. Her aching loins begged her to accept his advances. She unconsciously pressed back against him, pressing his dick on her hot, sensitive pussy. Zephyr then started moving a litte, thrusting his shaft between his sister’s cheeks, making her breathe out a soft moan. After a little more of this, and no protests from Fluttershy, he lined up his shaft with her pussy and pressed the tip against it, not penetrating quite yet.

“I’m still looking for that yes sis,” Zephyr said with a rather smug grin on his face as he teased his poor sister.

Fluttershy was feeling that ache more than ever now that the source of relief was so close. Just one word, and Zephyr would provide. Despite the anger from him taking advantage of the situation, saying no seemed like an impossibility as a haze of lust started washing over her.
Before it overtook her completely, she managed to say, “Bedroom.”

“Is that a yes I hear?” Zephyr asked.

“Yes, in the bedroom,” Fluttershy then said, almost begging.

In an instant, Zephyr dismounted, looking very pleased with himself, and gave Fluttershy what would have been a chaste kiss had he not kissed her rump. “I’ll be waiting,” he said before heading up the stairs to Fluttershy’s bedroom.

Fluttershy lied there on her couch, knowing fully well she was going to be fucking her brother, again, in a matter of moments. She quickly decided that if she was going to do that again, she might as well make him pay for it.

After coming up with a quick plan, Fluttershy headed upstairs to her bedroom. Upon opening the door, she saw Zephyr exactly where she expected him, on the bed, posing with his shaft at full mast.

“You know how to make a guy wait. My dick’s been aching ever since I got up here. Mind giving it a kiss to make it better?” he asked.

Fluttershy, however, had only one thing in mind for his dick. She climbed onto the bed, and very roughly forced Zephyr onto his back, her eyes filled with fury. “Oh no you don’t. You’re the one taking advantage of me here. So, I’m going to ride your dick until I get my relief. And if you make a single peep, I will break your nose, is that clear?!” she shouted in his face.

Zephyr made to speak, but then shut his mouth. He was starting to regret this.

Seeing that he was complying, Fluttershy lined up her pussy with his shaft, and shoved herself down as hard and as fast as he could. Zephyr had to bite down on a hoof to ensure he didn’t actually say anything as he cried out, and even then, he feared swift retribution. Instead, Fluttershy sat there for a moment before riding his dick at a frantic pace.

The sounds of sex quickly filled the room as both of them panted and moaned as Fluttershy continued. “Stupid brother, tempting me in the middle of heat season,” she muttered, the anger causing her to slam down harder.

After what felt like ages for both of them, Zephyr had hit his limit. He grabbed Fluttershy by her hips and held her down as he began to pump her full of his semen. This in turn caused Fluttershy to climax, and she let out a very loud moan as she said, “Yes! Fill me!” as she was finally getting relief from her heat.

Her womb was filled to the brim with his cum, and soon there was some dribbling out of Fluttershy’s pussy. As they both came down from their respective climaxes, Fluttershy was exhausted. She had put a lot of energy into this, and she let herself collapse on top of her brother. She barely had the energy to keep her eyes open, and she couldn’t stay mad at him for more than a fleeting moment.

“Um… can I talk now?” Zephyr nervously asked before shielding his nose.

Fluttershy looked up at his face to see he was genuinely scared. She quickly felt bad for being so aggressive towards him. “Yes, you can talk. Whew, I really needed that Zephyr.”

“Yeah…. Um, I guess I should go, shouldn’t I. I mean, I did… oh let’s be real here, I pretty much forced this on you. I knew you were in heat and I was dying to get a piece of flank. I…”

“Knew it would be easy?” Fluttershy finished.

“Yeah. Man, I sound like such a jerk right now,” Zephyr lamented.

“To be fair, the first time you asked after you got me pregnant. You were a lot worse back then,” Fluttershy said.

“Yeah. Oh, speaking of which, I got some of those morning after pills for you. Let’s face it, even I don’t like the idea of my sister being the mother of my foals.”

“And the last thing I need are two of you. One is already too much,” Fluttershy said.

“One of me is just right, besides, our foal would be far too pretty for this world,” Zephyr responded, getting a chuckle out of both of them. After a bit of silence, Zephyr then asked, “Were you really going to break my nose?”

“Maybe? I don’t know. I was just so mad and I was taking all of my anger and frustration out. I maybe shouldn’t, but I feel terrible about that,” Fluttershy said as she nestled herself against Zephyr more.

“I gotta admit, I do like how this ended better than the first time. You nearly did break my nose back then. Also I’m getting snuggles. You haven’t snuggled with me since we were foals,” Zephyr said somewhat wistfully, looking back on those night when his big sister would comfort him after having a nightmare.

“It was innocent then. Now, not so much. Especially since we just had sex. And your dick is still inside me.”

“Hey, I’m the one on the bottom right now. That’s your problem,” Zephyr said with a smirk.

Fluttershy giggled in response. With a little effort in moving her hindquarters up, Zephyr’s softening did slid out of her, releasing a good amount of cum from her loins. She then set herself back down, not caring about the mess right now.

“I feel empty now,” Fluttershy said.

“I can fix that, just say the word,” Zephyr said as he gave her a little nuzzle.

“Mmm, not right now. I want a nap, and this is a really comfortable spot,” Fluttershy said, nuzzling Zephyr back before letting her eyes shut.

“I’m I really just a comfy bed to you?” Zephyr asked in mock protest.

“Just right now,” Fluttershy said before settling in and quickly falling asleep.

Zephyr had to admit that she looked adorable like this, and couldn’t help giving her a kiss on her head. He wrapped his hooves around her to hold her a little closer. He wasn’t tired, but he was very content with watching his sister sleep in his hooves.

“Sleep well sis. Love you,” he quietly said.

Fluttershy awoke and found herself snuggled up on top of Zephyr, right in the same position she was in when she fell asleep. She looked up to see Zephyr was still awake, lovingly holding her close and watching her.

“Sleep well?” he asked.

“Mmm, yes. How long was I asleep?”

“Two hours. Sun’s starting to go down,” Zephyr responded.

“Really? I didn’t know it had been that late in the day when we… you know,” Fluttershy said.

“Sis, we fucked each other, plain and simple. Well, you more fucked me. More scary than hot, but hey, I admit I kinda deserved it.”

“Yes you did,” Fluttershy said, giggling a little bit before relaxing again. “Oh dear, I need to check on the animals and get started on dinner.”

“Might wanna clean yourself up first. Wanna take a shower together?” he asked.

“No, I feel we’ll end up taking longer than if we took separate showers. I’ll take the first shower,” Fluttershy said.

“Fine by me. And I’d help with the cooking but… you know my cooking skills aren’t that great.”

“I know. But I can show you a few things. Get you to start cooking more,” Fluttershy said.

“Might as well if it means I don’t have to eat frozen hayburgers and salads as much,” Zephyr responded.

After quick showers from both of them, Fluttershy tended to her animals, who were relieved that she was feeling much better and was back to her usual self. Afterwards, she started on dinner for both her and Zephyr, getting him to help out. She went with something simple that Zephyr should be able to do at his own place later, a one pot meal of pasta with asparagus, and mushrooms mixed with a creamy alfredo sauce. She had Zephyr cut the vegetables up, and stir the pot as she got other parts of the meal ready. A few store-bought rolls and a butter dish made for the side dish, and she got some sparkling cider, non-alcoholic, to drink.

Dinner was a fairly normal affair, a little conversation about how things were going while they both enjoyed the food. At the end of the meal, Fluttershy put away the leftovers as Zephyr relaxed a bit.

After some silence from both of them, Zephyr turned his head towards the kitchen and asked, “So… what happens now? I mean, you haven’t kicked me out, so I guess you kinda want me here, right?”

Fluttershy gave that question some thought as she finished up with the dishes. After she set them to dry, she came out of the kitchen and said, “Well, I’d be lying if I said I didn’t want to have sex with you again.”

“I won’t say no. We’ve already fucked twice, a third time wouldn’t do any more damage. And you’re already going to be pregnant. Be a waste if you took those morning-after pills now,” Zephyr responded.

“I don’t think that’s how that works, but… I certainly can put it off for a bit. I mean, I like the idea of having a foal but-”

“You don’t want me as the dad. We talked about that earlier,” Zephyr cut in.

“Right, sorry.”

“Don’t be. I ain’t ready to be a father quite yet. Still trying to get on my own four hooves, you know,” he said before getting up from his seat, “So, wanna get straight back to the bedroom?”

Fluttershy rolled her eyes with how eager her brother was. “Alright. To the bedroom.”

“Ladies first,” Zephyr responded. Fluttershy knew fully well he wanted an eye-full of her flank. So, she led the way, making sure to flick her tail out of the way to give her brother a full view of her pussy.

This continued until they reached the bedroom and Fluttershy started climbing onto the bed. Just as she was about to get her hindquarters on, Zephyr rushed forward and gripped her by the flanks as he started kissing and licking her cheeks, making Fluttershy yelp a bit before relaxing in his grip. “Mmm, you really like my butt, don’t you.”

“Oh yes, I love your ass,” Zephyr admitted as he continued worshipping Fluttershy’s rump, kissing that soft, supple flesh and getting his nose filled with her scent.

His muzzle soon drifted down to her pussy, and he gave it a kiss before he started lapping at those soft folds. Fluttershy let out a heavy moan as that began, and she let him do as he wished right now. She soon felt his tongue penetrate her, making her gasp and giggle a bit. “We never got to this last time,” she moaned out, “You’re good at it.”

Zephyr pulled back to respond. “I’ve taken a number of mares to bed on my more lonely nights. I’ve had lots of practice,” he said before going back in to give her sister’s pussy one last lick and kiss before climbing onto the bed. He moved in front of her and presented his shaft at full mast for her. “Mind returning the favor?”

Fluttershy rolled her eyes with amusement on her face. She scooted closer, finally getting all the way onto the bed, and gave his shaft a long lick from bottom to top, kissing the tip just before she took it into her mouth. She swirled her tongue around the tip and suckled on it, making her brother groan from pleasure. Soon, she started bobbing her head up and down, taking more of his shaft bit by bit. She forced back a gag when she eventually got to the back of her throat. She pulled back a bit, smiled as best as she could with a dick in her mouth, took a deep breath and forced his shaft down her throat.

Zephyr let out a cry that would’ve made many question his masculinity as Fluttershy deepthroated him. Watching his sister take his whole shaft was hot, and yet Fluttershy still looked adorable. The tight confines of her throat were quickly driving him close to an orgasm. But, as he hadn’t let Fluttershy have one yet, he decided to stop it there for now. Besided, he wanted to do something else.

Fluttershy felt her brother’s hooves coax her head off of his shaft, and she looked up at him in confusion for a moment. Zephyr then pulled her up close and gave her a rather nervous kiss on the lips. After a moment of shock, Fluttershy returned and deepened it, sliding her tongue into her brother’s mouth. They were willingly, and soberly, having sex with each other. There was no sense holding back anymore.

The two wrestled tongues for a good while before they both pulled back and looked deep into each other’s eyes. For a moment, there was no pony more beautiful or handsome than the ponies they were gazing at right now.

“I love you sis,” Zephyr whispered.

Fluttershy giggled and said, “I love you too brother.”

She let Zephyr push her onto her back and kiss her again. As they kissed, Fluttershy brought a hoof down ot guide Zephyr’s dick to her pussy. Once it was pressed up against her, Zephyr pulled his head back from the kiss and looked at her, silently asking for permission. Fluttershy nodded, and Zephyr gently popped his dick inside of her. He slowly pushed himself the rest of the way in as Fluttershy moaned and shivered from the pleasure, all the way until he hilted inside of her. He stayed there for a moment, savoring the warmth and embrace of his sister’s pussy. Soon, he pulled his dick out, leaving only the tip, before slowly easing himself back in and repeating.

Fluttershy was loving every second of it. The sex before had simply been to relieve her of her heat. Now, this was genuine love making. Every inch of Zephyr’s shaft stimulated her, making her shiver with pleasure each time he pushed himself back inside of her, his medial ring giving her a much sharper moment of pleasure.

Zephyr soon started thrusting faster, and was breathing heavier with each thrust. Fluttershy moved a hoof to cover her mouth as her moans started to get louder. But, a moment of clarity that it was only Zephyr and her, and that the only ones nearby who might hear them were her animals, she moved her hoof away and let herself moan as loud as she needed.

These moans spurred Zephyr on to go faster and faster, until they were both panting, moaning and groaning. Fluttershy wrapped her hind hooves around Zephyr’s waist, keeping him from pulling out all the way, and she hungrily brought his head down to bring him into a sloppy, lustful kiss. Their tongues immediately danced as Zephyr’s pace turned frantic, nearing orgasm.

Soon, they both hit their peak, sending them higher than any previous sexual encounter had made them. Fluttershy had been first, letting out a loud cry as that paralyzing wave of pleasure rolled through her, unintentionally breaking her kiss with her brother. Zephyr hit his moments later as Fluttershy’s pussy milked him for everything he was worth. He slammed himself in one last time and filled her up with his seed once again, grunting with each spurt his dick shot out.

They both collapsed as the came down from their respective orgasms, still feeling high from the afterglow. Neither of them knew just how long they lied there, but it had gone dark, and they enjoyed every moment of their time lying together.

Once Zephyr had the strength, he rolled both himself and Fluttershy over so she was on top of him, positioned much in the same way they were before.

Fluttershy let out a satisfied sigh and said, “That was amazing.”

“I aim to please,” Zephyr responded with a chuckle.

“Mmm, I’m glad. Please tell me you don’t have another round left in you.”

“Oh don’t worry, I think it’s time I got some rest as well. Whoo, that was really something.”

“Agreed,” Fluttershy said as she nuzzled her brother right below his chin, not minding the scruff down there. “Goodnight Zephyr.”

Zephyr chuckled again and said, “Goodnight Fluttershy.” With that, they both closed their eyes and let themselves drift off to sleep.

Zephyr stirred awake, something had been shifting by him. Of course, he quickly remembered what happened last night and looked down to see Fluttershy had tried to slip out of his grasp.

“Um, morning,” she said, “Sorry for waking you.”

“Sorry? I just woke up to the face of an angel,” Zephyr responded. The heavy blush on Fluttershy’s face was priceless to him, especially since she had trouble finding the words to reply. He then moved himself forward and gave his sister a tender kiss on the lips. He then pulled back and said, “There. Better?”

“Better,” Fluttershy responded, “Still not that great at taking a compliment.”

“Oh, you’ll get used to it. What are you getting up for? The bed is much more comfortable, even when I’m not in it,” Zephyr said.

“Morning-after pills.”

“Oh, right. Yeah, best get that taken care of now,” Zephyr replied. Realizing he left his saddlebags downstairs, he actually got up to go get them. “Wait here, I’ll bring them up for you.”

“Oh no, I-”

But Zephyr didn’t give her the chance to protest. He went downstairs, dug the pills out of his saddlebags, and came back up with them. “There, told you I’d bring them up for you,” he said with a bit of a smirk.

Fluttershy took them and gave him a kiss on the cheek for it, then headed into the bathroom to take those pills.

Zephyr was feeling unusually productive this morning, so he started gathering up the soiled sheets and blankets from yesterday’s antics. “Yo sis, could you remind me where you put your wash?” he asked, turning to the bathroom to ensure Fluttershy heard him.

A moment passed, and then another. Zephyr knew for a fact he hadn’t muttered that or anything, so he decided to check on Fluttershy. The bathroom door had been open, and Fluttershy was standing in front of her sink, staring at a couple of pills on her hoof. “Sis? You okay?” Zephyr asked, startling Fluttershy bit.

She quickly composed herself and said, “Yeah, I’m okay. It’s just….” Fluttershy couldn’t find the words to finish that sentence.

“Are you… actually thinking of having this foal, the one we both agreed we didn’t want?” Zephyr asked. Before Fluttershy could respond, Zephyr cocked his head to one side in thought and said, “Saying it like that, it sounds rather terrible, doesn’t it.”

“It does. And… I guess a foal from both of us wouldn’t be so bad. I mean, I could say that I got pregnant from a random stallion. And no, that’s not a lie, you are a very random stallion,” Fluttershy said with some mirth.

“I don’t know whether to be offended or flattered, so I guess I’ll take flattered,” Zephyr said with feigned pride, making them both laugh a bit. Zephyr soon got back to the matter at hoof. He sidled up next to Fluttershy, leaned into her, and said, “I’m not sure we should lie. I don’t like the idea of my foal not having his dad, you know. I mean, this is going to be taboo up the wassu, a brother and sister having a foal, but I think that would be better than lying about it. I mean, we should at least tell mom and dad if we’re going to do this.”

Fluttershy slowly nodded in response. After what felt like hours staring at those pills, Fluttershy took the bottle and placed those pills back inside, closing it up afterwards.

Zephyr pulled Fluttershy in for a big hug and said, “Looks like we’re going to be parents. Heh, never thought everything from yesterday would lead me to being a father. You know, as much as I should regret it, I kinda feel glad we did it, you know?”

“I know,” Fluttershy responded, “We’ll make it work.”

“Yeah. Oh, might as well ask now, is it okay if I sleep with other mares still? I still want to try to get Rainbow Dash to let me help her through this heat season.”

Fluttershy let out a sigh and shook her head in amusement. He was still the same old Zephyr. “Yes, you may.”

“Sweet! Um, not that I’ll forget about you since… well… you know. Anyway, I want to try to catch her early today. Need anything before I go?” Zephyr asked.

“Just take those pills with you. Of all mares, Rainbow Dash won’t likely want to have foals anytime soon.”

“Right, almost forgot those,” Zephyr said before snatching the bottle up. “Thanks sis, I’ll be back later tonight if things don’t go well.” He then took off, quick as a flash, leaving Fluttershy alone in the bathroom. Before Fluttershy knew it, he had come back looking a little sheepish. “Um, I might want to clean up before I do that. Wanna take a shower together?”

Fluttershy let out yet another sigh and said, “Sure,” knowing fully well it could devolve into more sex.

“Great. Ladies first,” he said.

Fluttershy had to chuckle at that. Thinking more sex would be inevitable, she walked to the shower with her tail held to the side, once again giving him a clear view of her pussy. She got in turned the shower on, and then found herself pinned to the wall by Zephyr as he gave her a lustful kiss.

Fluttershy wondered if her brother would even remember Rainbow Dash at this rate.
