Ventrilocest

Applejack tried her best not to stare at her brother as she and Sugar Belle worked out in the orchard with him. She kept expecting Big Mac to be glancing at her when he thought she wasn't looking. But he hardly ever looked her way. If anything, he was making a point to not look at her unless it was to directly interact with her. And there was nothing strange about it, despite how much she was trying to see anything odd in his behavior.

Maybe Sugar Belle was wrong about him. Maybe he had lied to her. Maybe his problem was because of something else. None of it made any sense, and as the day went on, it only seemed more absurd. Applejack felt incredibly nervous about the idea that Sugar Belle had for them that night. But she swore up and down that it was the only way, and she begged her to do it.

If Sugar Belle was wrong, tonight would be a disaster. Even so, Applejack hoped Sugar was wrong. It would be awkward. But they'd all be able to laugh it off over many rounds of cider. They would get past it. It would be okay.

After the sun set, and it was too dark to work any longer, the three of them headed inside to get cleaned up and have dinner.

"Hey Mac," Sugar Belle said. "After dinner I'm going to head into town. I want to see that new movie with Miss Cheerilee. So I won't be back until late. "

"Alright," he said without a second thought.

After dinner, Applejack and Sugar Belle cleared off the table and did the dishes. Big Mac gathered up the garbage to bring it to the trash can outside the back door. Sugar nudged Applejack's shoulder and leaned over to whisper.

"Okay now, just like we rehearsed..."

Applejack swallowed hard and nodded. Sugar Belle smiled and left before Mac came back inside from the back yard. Mac's eyes looked around the kitchen quickly.

"She leave already?" he asked.

"Yup. So it's just... the two of us," she said. She opened the fridge and grabbed a bottle of cider. Normally she's enjoy just sipping it, but she drank it quickly this time. "Well, I'm gonna head upstairs," she said. "Don't stay up too late."

Upstairs, Applejack waited. In the quiet bedroom, all she could hear was her heart was racing in her ears. She didn't have to wait long. After only a few minutes she heard him shuffling around the first floor and then the heavy hoofsteps of him coming upstairs. The door opened.

"Applejack!?" Big Mac asked, surprised to see her.

"Hey," she greeted.

"Why are you in my bed?" he asked. Indeed she was laying in his bed. The one he shared with his wife.

"Well-" The words hitched in her throat. "Sugar Belle is out for the night," she said. "So I figured... now that we're alone..." she winked at him. Big Mac somehow managed to turn a darker shade of red.

"I- I- What are you talking about!?" he asked.

"Sugar Belle and I were talking," Applejack explained, looking down at the bedding. "And she told me certain things... About you. And about how you feel..." She looked back up at his eyes. "About me." Big Mac's jaw dropped open.

"AJ! AJ I'm sorry! I- I never- I would never-!" He stammered, looking like he was about to cry. He lifted a hoof to reach out to her from the far side of the room, but he immediately put it back down and didn't dare move any closer than the doorway.

"Mac, it's okay. I mean, yes, I was a little shocked when I found out... Okay, a might shocked."

"AJ I'm sorry!"

"I said it's okay. I know you're a good pony and you would never... act on the way you felt about me."

"Never!" he assured her.

"But she told me that it's been causing some... issues for you two." Big Mac's shame only deepened. "Sugar Belle want's your foals, Mac. And she told me that she doesn't care how she gets them. That's why she asked me to... help." Big Mac's eyebrow raised just as far as it could while still being attached to his face.

"Help?" he asked.

"Mhmm." Applejack nodded. She rolled onto her back and spread her legs, putting her hoof between them just to cover her modesty. "So if this is what it takes to get you off... If- this is what you want..." She patted her crotch with her hoof.

Big Mac was a hurricane of emotions. He could scarcely believe his eyes. He yanked on his ear with his hoof to see if he was only dreaming about this again. But he was surely awake. He wanted so much to just pounce on her and seize his forbidden desire at last. But one final moral hurdle stayed his hoof.

"But I'm married!" he said. "What about Sugar Belle!?"

Applejack smiled. "Why do you think she went out for the night? Whose idea do you think this is?"

Big Mac's legs trembled with excitement. It was too good to be true. In all of his wildest dreams he would never have thought that it was actually going to happen. But here she was! He closed the door behind him and started walking towards her.

"Wait!" Applejack said. He froze, as though he had done something wrong, and this incredible opportunity was about to be taken away. She had come to her senses. Of course she did. And she wouldn't be able to live with him anymore.

"Wait," she repeated. "Could you just... turn off the light?" she requested.

"But... I want to see you!" he said.

"I know, Mac. I know. But I'm still trying to get used to the idea of this myself, okay?" she said. "So it would just be easier for me if I didn't see you."

"Oh, okay..." he complied. He wasn't about to argue with her about how they were finally going to do this. He turned around and switched off the light. In the late night, the room went pitch black. Even if it wasn't a moonless night, the curtains were drawn tightly shut. Big Mac couldn't tell the difference between his eyes being opened or closed. He couldn't even see his hoof in front of his face. His hoof reached out in front of him like an antenna, feeling around for his surroundings. Unlike her brother, Applejack had excellent night vision for a non-thestrial.

Meanwhile, Applejack had quickly slid off the backside of bed, down where Sugar Belle was hiding behind it. Sugar Belle grabbed Applejack's hat and put it on to cover her horn as she silently climbed up into the spot where Applejack was. The bed rustled and creaked as the mares moved.

"Applejack?" he asked into the room.

"I'm right here big guy," Applejack said, keeping her head near Sugar Belle's. They peered into the dark as the blind stallion followed the sound of her voice toward the bed. His outstretched hoof touched the edge of the bed and felt around on the bedding until he touched Sugar Belle's hoof. He pulled his hoof away as though he had touched a hot stove.

"Come on," Applejack encouraged him.

Big Mac reached out again. His hoof was trebling almost as hard as his breathing. He placed his hoof on Sugar Belle's leg again. It was an innocuous contact, barely on her calf, above her ankle. For all the platonic times he had ever touched his sister in the past, her mere fetlocks under his hoof felt so incredibly alluring.

He was practically hyperventilating as he slowly moved over her. His every muscle shaking in fear that at any moment he might wake up from this dream.

"You smell so good," he said.

At Sugar Belle's behest, Applejack had awkwardly masturbated earlier. She wiped what wetness she had into her sister-in-law's fur, replacing as much as she could of Sugar Belle's scent with her own.

His hoof moved so very, very slowly up Sugar Belle's leg, keeping to the outside of her thigh. His hoof grazed the hair of her tail laying beside her. Sugar Belle had taken care to style it just like Applejack's. Combed straight and tied in one of her ribbons. She'd had plenty of practice doing so from past roleplay nights. He brought his face closer to hers and then stopped, hesitating yet again.

"C-can I- k-kiss you?" he asked nervously, practically whimpering the words. His voice was trembling even harder than the rest of him.

Applejack had never seen him so vulnerable before. Even after everything that had happened, her heart went out to her brother, whom she did love very much as family. It was plainly evident just how much inner turmoil he had been silently harboring all these years. To be so close to the object of his desires, living in quiet desperation, knowing that his feelings it would never, ever be returned. Living with the overbearing shame of thinking that he was a bad pony for even having such feelings, even if he never intended to act on them.

But he wasn't a bad pony. Applejack understood that.

"Of course you can kiss me," Applejack whispered beside Sugar Belle's head. She backed away as Mac leaned down. His puckered lips trembled against Sugar Belle's. It was a light, almost chaste contact at first. Even now, he still feared committing to the action. Sugar lifted her head the slightest degree to kiss him back a bit, encouraging him to kiss her properly. Mac pressed his lips against hers harder. The brim of Applejack's hat grazed his cheek.

Applejack just waited off to the side, watching everything unfold. Trapped so closely nearby, it wasn't like she had much choice. And she needed to watch them both to be ready for her cues from Sugar Belle, and to react to Big Mac. Though between the two of them, she was watching him more.

With his nose against her cheek, Sugar Belle could feel his warm breath, shallow and panting rapidly. She wrapped her hooves around him and opened her mouth, really getting into the kiss. Big Mac responded in kind with equal passion, kissing her deeply now. His tremendous fear slowly started to dissipate.

For all the times that Applejack had seen him kiss Sugar Belle, there was a strange fascination for her in watching the way he kissed his wife, thinking he was actually kissing his sister. It was primal. There was a raw, desperate, hunger to it. He kissed her with an animalistic fervor, as though this was his one and only chance to have this opportunity, and he wanted to get all that he could of it.

Sugar Belle ran her hoof down along his side and then under his belly. Big Mac gasped at the contact of her hoof on his penis. He had taking care to arch his back to keep it from touching her body at all. He pulled away from the kiss and reared up, shamefully trying to back away from her. But Sugar Belle just held onto his shaft more firmly with her hoof. Applejack looked from behind the bed. Even in the very low light, she could see the silhouette of the behemoth that was 'Big' Macintosh's namesake.

"Wow! It's so big!" Applejack gasped. "Sugar is a lucky mare."

"It's- it's big for you, AJ," Mac said, standing up a bit prouder.

"Just for me?" Applejack asked, addressing the core problem at the heart of the whole thing. For a moment, Big Mac nodded in shame to nopony in the pitch darkness.

"E- eeyup..." he answered.

"So y'all did roleplay?" Applejack asked.

"She told you a lot, huh?"

"Eeyup," Applejack replied. "That it was the only thing that got you hard."

"Not this hard," Mac said. Sure enough, Applejack watched as Sugar Belle pulled down on his dick with her hoof to rub it against herself, but it was like trying to bend a steel beam. He adjusted himself to let her move him. At last, the side of his shaft brushed against her hot marehood.

"Ain't nothing like the real thing, huh?" Big Mac felt the soft marehood against the side of his dick. "Well come on big guy. I'm right here waitin' for ya," Applejack coaxed. Sugar Belle rubbed his dick against her pussy a little more. Big Mac was a stuttering mess.

"App- pple J-J-J... AJ? C-c- Can I p-put it..."

"You sure can," Applejack said, lowering her voice into a sultry purr. "I want you to put it inside me."

He shifted back a bit until he was out of her hoof's reach. He took his stiff shaft in his hoof and rubbed the tip of it against her pussy, getting the head of his dick plenty wet with her arousal. He pressed the blunt tip against her tight entrance. He applied a little more pressure, finding that getting it inside might be no easy task.

"AJ I'm gonna..." he trailed off, waiting to give her one last chance to back out.

"Well come on big guy. I'm right here waitin' for ya," Applejack coaxed.

Big Mac pressed a bit harder. Even as accustomed as Sugar Belle had been with his equipment, she had never experienced him like this. Usually, 'full mast' for him meant that he was still a good deal spongy and flexible. But tonight it was like the damn thing had been carved from wood. She felt a brief pang of panic as he tried harder to get it inside her. But a deep breath and exhale later, she was finally able to physically relax enough.

The tip of Big Mac's dick slipped inside. Sugar Belle gasped, but he gasped louder.

There in the dark, blind to the truth, Big Macintosh reveled in the euphoric illusion of his fantasy come to life. It was finally happening. In all of his wildest dreams, he would have never have dared to think it would ever come to pass. But he was finally having sex with his sister whom he had secretly lusted after for so long. It was so warm and wet and tight. It was just as he imagined. Better than he had imagined!

"AJ!" he moaned. He shifted forward and pushed more of his length into Sugar Belle. At the height of her estrus, she was as pliable and well-lubricated as she possibly could be. He slid into her with relative ease, considering that it felt like her vagina was being fed a tree trunk. She was already feeling full by the time his medial ring slid inside her. She had been so used to being able to let him hilt her that she hadn't worried about it. But he was harder tonight than she had ever experienced before.

Big Mac bottomed out in her with still a couple inches of dick to go. With another small thrust, he pushed a little more. Not hard, but as a steady, firm pressure. The muscles of Sugar Belle's vagina stretched just a bit more as he sank the last of his shaft into her and shoved everything inside her upwards to make space, forcing the air out of her lungs in a grunt. If Sugar Belle was in any kind of real pain, she needed only to speak up or yelp and the jig would be up. But she kept herself quiet as she tried to accommodate her husband's sheer size as though it were their first time all over again.

"Are you okay?" Big Mac asked.

"Yeah," Applejack said, assuming it to be the case with Sugar not crying out. "I'm just getting used to my big brother being inside me." Sugar grunted again as she felt Mac somehow throb even thicker as Applejack played up the taboo nature of the evening. Sugar knew how much it would turn Mac on.

"It is," Mac said, running his hoof along Sugar's Belly. "It's inside you. I'm inside you! It's-" He leaned down and hugged Sugar on the bed. "It's so good! You don't know how long I've wanted this, AJ! I love you! I love you so much!" He kissed her. She kissed him back. Their tongues danced over one another in their mouths. Applejack watched and waited for him to break the kiss. Once he did, she leaned close to Sugar.

"I love you too, Mac. Now come on, show your little sis how much you love her," Applejack whispered.

Big Mac needed no further instruction. He shifted his weight back upright for better leverage. He planted his hooves on either side of Sugar Belle's waist and started to pulled back. He barely got his medial ring out before he pushed it back in as deep as it could go, giving Sugar's cervix another good shove and making her grunt again. Mac could tell no difference between her little noises or Applejack's. Either that or he simply didn't notice.

His every thought was focused on the feeling of the tight, wet, warmth wrapped around his dick. He slid in and out of her, trying his best not to bottom out too hard, but also still wanting to hilt her. If he was going to live out the fantasy of finally fucking his sister, he wasn't going to do it half way.

He got into a good rhythm, rocking back and forth, sliding in and out of her. His every nerve was on edge. It was a torturous combination of so many feelings. At once, being turned on so very much, and having not gotten off in far too long; Coupled with the internal conflict of not wanting this experience to end, against his desire of wanting to just enjoy it completely before he figuratively, (or literally) woke up from this dream come true.

The mare under him quivered and trembled with a guttural moan. A rush of fresh juices spurted out of her pussy from around his shaft, wetting them both. As their hips slapped together, little droplets spattered everywhere, including onto Applejack's cheek. Mac could feel her pussy pulsating around his dick.

"You cumming AJ?" Big Mac asked.

"Sure am, big guy," Applejack said, trying to emphasize her voice with a moan of pleasure as she wiped her cheek. "My big brother is making me cum!"

The words were music to his ears. That along with the wet slaps of their hips and the moans of a mare's pleasure, it was a symphony of sex. Big Mac redoubled his efforts. All Sugar Belle could do was just hold on to the bedding as he increased his pace, depth and intensity. His rhythm began to grow more and more erratic.

"AJ I'm- I'm almost there!" he said, trying to stave off his climax just a few moments more. Even in the throes of the most intense passion of his life, he still had the presence of mind to ask his sister, "Where do you want it?

Sugar Belle locked her legs around Big Mac's waist, keeping him from pulling out.

"Don't stop," Applejack said. "Keep going!"

"I'm about to-" he grunted. "What if you get-" Mac asked.

"I want you to cum inside me, big brother!" Applejack said, as she had rehearsed. "I want your seed to get me pregnant! Pump your incest foals into your little sister!"

Big Mac's balls tightened up as her dirty talk sent him tumbling of the edge, past the point of no return. He wrapped his hooves around Sugar Belle and held himself close to her as he slammed it home one final time, bringing to to bear hard against her cervix, lined up squarely against the tiny opening to her final barrier. She could feel him flaring inside her, stretching the deepest parts of her vagina even more. The tiny entrance to her womb parted just a bit against his broad flare.

Big Mac grunted and groaned as he came harder than he ever had before in his life. His balls ached from having been so full for so long, and now they emptied at long last. He saw stars as his eyes rolled back in euphoric bliss. The first rush of his cum rocketed up through his shaft and spattered hard against the back of Sugar's vagina and instantly filled the modicum of space left.

It was followed quickly by another torrent of semen, not as forceful as the first, but easily with more volume. With her pussy already overfilled, and his flare making an airtight seal, it had nowhere else to go but deeper inside her. There was so much pent up cum that it was starting to displace his dick, and pushed him out a little. Sugar Belle squeezed his waist with her legs, pulling him into her harder, and pushing back against the growing pressure inside her pussy. She could feel his potent seed flooding into her needy, fertile womb, dousing the flames of her estrus at last.

Big Mac's entire body shuttered and nearly collapsed on top of her from the release. He hugged and kissed her desperately as his cock continued to spurt the last few ropes of cum deep inside her. Sugar Belle felt his tears fall onto her cheek. Even Applejack could hear the wet sniffles of him as he cried, pressing his face into Sugar's shoulder, burying his face in her mane.

"I'm sorry," he cried. "I love you so much Applejack! Thank you! Thank you so much!" He cried harder into Sugar Belle's mane, trying to muffle the sobs of his catharsis. Sugar hugged him back and just held him while he let it all out. "I'm sorry!" He spiraled between gratitude and guilt. Sugar Belle just rubbed his back with her hoof and let him cry. He let out all the tears of shame and joy and guilt alike.

"Am I a bad pony?" he asked. Applejack carefully leaned in next to Sugar Belle's head to whisper.

"No. You ain't a bad pony. You're a good pony. You're my brother and I love you," Applejack said, meaning every word of it. He cried into Sugar's shoulder a bit more until he finally calmed down.

"Can you... can you stay with me," Big Mac asked. "Can you stay with me for tonight? I just want to hold you." He squeezed Sugar Belle harder.

"Alright," Applejack said. "But I'm getting out when Sugar Belle get's back. So don't expect to be waking up next to me in the morning." Big Mac whimpered like a little colt. "No arguing."

"Okay."

Big Mac and Sugar Belle shifted on the bed. He lifted himself up off of her and she carefully rolled over while he did his best to keep him inside her, intent on never leaving his sister's pussy ever again. Then they both moved together onto their sides with him laying behind her to be the big spoon, entwined together until they fell asleep.

Applejack silently laid on the wood floorboards beside the bed until she heard the telltale sounds of her brother snoring. She knew that once he was out, he could sleep through a tornado. She stood up and got her hat back from Sugar Belle who was likewise sound asleep, and then she silently walked back to her own bedroom.
