Celestia's Relaxing Vacation

Human Celestia left her limbless sister's corpse laying on her desk, head hanging off one side of the desk by a flap of skin that was the only thing holding it on. Her magical counterpart had helped clean her up and get her dressed again, though had let her keep her cock, which bulged her pants rather obviously. She couldn't go soft no matter how hard she tried, not with the memory of Luna's deathgasm clench still fresh in her mind. She wanted more.

Luckily for her she knew just where to get more. Applejack and Big Macintosh had volunteered to stay after school that day to help get ready for an upcoming school function, and would probably just be finishing up. So she went towards the lunch area where they would be working. She didn't see evil Celestia or Twilight, but knew they were following invisibly; they'd want to see how she handled herself before joining. She shivered with excitement, both because of the new found joy of murder and because she knew they'd kill her if she didn't do well, or maybe even if she did. It wasn't like she could do anything to stop them from killing her, so she may as well have fun before they do.

She heard Applejack and Big Macintosh talking in the kitchen, so she headed that way. She paused at one of the crates they had been carrying in, picking out three bottles of cider. One of them she cracked open, and slipped a pill that quickly dissolved within. Her alternate self had told her it could disable someone for several hours, and she had an amusing plan to see how much Big Mac really wanted to have at his sister.

"Hello you two," Celestia said as she entered the kitchen area where Big Mac and Applejack were, "Working hard? Thanks again for coming to help."

They were both wearing their typical attire, with Applejack in a green and white shirt, blue jean skirt, and high boots, and Big Mac in a red and brown shirt and blue jeans. Celestia wondered if students had a closet full of the same outfit because they all seemed to wear the same thing to class every day. She gave both of them a good look over, which neither seemed to notice as they waved at her.

"Just finishin up," said Applejack, "Had quite a load. You workin late too?"

"Something like that," smiled Celestia. If only they knew what she was thinking.

Celestia handed each of them a bottle of cider, which each took without question. She popped the top off her own bottle and the two others did the same with theirs. Whether they were thirsty, or just to be polite because she had handed them one, they started drinking.

"Actually I was looking for you two for a bit of an experiment," Celestia chuckled.

"Experiment?" Applejack asked, "What kind of... ex--per... whoa ah'm dizzy all the..."

Applejack collapsed and dropped the rest of her drink onto the floor, bouncing and rolling across the floor to spill the rest of it into a puddle. Big Mac was quick to catch his sister with his free arm, then put down his drink and pulled her over to a chair where she slumped, leaning back and a bit of saliva dribbling from the edge of her mouth.

"AJ?" Big Mac shook her.

"Well that was faster than I imagined," Celestia pondered, "Very effective indeed."

Big Mac looked back at Celestia, one eyebrow raising as he stared at her, too confused to be angry that she just drugged his sister yet.

"Let me explain," Celestia started, it was easy enough to cut him off, if he was going to say anything at all, "This is about those stories we confiscated from you, and if you want your family, particularly your sisters, to know about them."

"What." Big Mac held AJ up in her chair and looked over at Celestia. It was more of an exclamation of confusion than a question.

"Did you think we would do what we did last time you were in trouble?" asked Celestia, "Where you bend me over my desk and I agree not to tell your family? No, your story has inspired me. I want you to bend her over the counter, right here and now while she's out of it, exactly how you did in your story." Amusingly, he had drugged her in his story too, so she knew he'd thought about it before.

"Um... nope," Big Mac's eyes got large, but he did glance over at AJ as if pondering. He also blushed a deep red, biting his lower lip slightly. He didn't seem angry at the proposal, at the very least.

"What's the problem?" asked Celestia, "You can have your way with her just like you want. Then we'll clean her up, and tell her she passed out for a few hours."

What Celestia didn't tell him was that his sister wasn't in fact out of it enough to forget this event. She was quite conscious, just unable to move or speak on her own. She would hear, see, and feel what happened next.

"Nope?" Big Mac's answer was less certain this time, glancing at his sister again and really giving her a good look over. His blush deepened... and Celestia could see from the front of his pants that he wasn't really against the idea.

"Oh come now Mac," said Celestia, "You should be thanking me for this. You can live out your greatest fantasy and avoid getting in trouble in the process."

"Um... privacy?" Big Mac asked.

"Oh no," said Celestia, "If you want to do this, I get to watch. Come on now. It's not like watching you fuck is the most perverted thing I've done with you."

Big Mac finally nodded, turning back to his sister. He shook her again as if to check and see if she was awake yet, then pulled her up from the seat. He carried her across the room in both arms and draped her across one of the kitchen counters, face down and bottom facing him. He paused as if deep in thought for a few moments, then took her by both legs and turned her over so that she faced upwards.

"Yes that's it," said Celestia, "You want to see her eyes as you have your way with her, not to mention fondle those breasts. You do like that, if I remember correctly."

Big Mac clenched his teeth together, clearly not liking the audience or the comments, but didn't look like he was going to give up this chance. His hands shook as he knelt, pulling first one boot and then the other from Applejack's feet, leaving her feet with two apple designed socks. He then reached up beneath her skirt, and tugged down her panties, which amusingly were pink except for a large apple right over where her slit would be. Tugging them down and pulling one foot out of them, he left them dangling from the other. He pushed her legs apart more, pulling her skirt up and getting a good look at the hole that was making him rock hard.

For a moment he looked entranced by it, then slowly leaned his head forward. One hand grasped her rump, pulling his face up to her waiting fun hole. He took a deep breath to smell her, then ran his tongue from the bottom of her slit up to her clit, twirling around it before sliding back again. He then pressed his mouth against her and kissed her there deeply, pushing his tongue within and taking laps as deeply as he could. As he did so, he undid his pants with his other hand, tugging down the front of his own apple underwear to allow his throbbing impalement rod to flop out. Applejack's pussy responded, growing wetter with each lick.

"Good, taste that pussy," Celestia purred, moving closer to them and kneeling next to him, "Imagine how good it will feel wrapped tightly around that jumbo sized cock of yours."

Celestia stroked her hand down his back as he ate his sister out, making him tense up, but he didn't slow down. After he had tasted her for several minutes, he finally stood back up. He took a deep breath, pulling her rump up to the edge of the counter, and flopped his incestuous shaft against her pussy. He slid his hands up her body, unbuttoning her shirt and pulling it open. He licked his lips as he then pushed her bra up off of her breasts, not bothering to take it off. His hands immediately began to knead those plump pliable orbs.

Unknown to him, Applejack was completely aware of his actions. Anger and embarrassment burned up inside her, but as much as she tried to move or speak, all she could do was stare blankly upwards and drool out one corner of her mouth. She screamed inside her head when she felt her brother's shaft smack against her moist cunt, and more when her brother began to fondle her breasts. Helpless tears rolled down her face as her own brother prepared to rape her and the principal she trusted encouraged him.

Big Macintosh pressed his shaft forward, pressing between Applejack's lips and popping inside with a moist slurp. The normally silent man couldn't help but moan at the feeling of her pussy encompassing him. He could swear it was the best that he'd ever had as if the sibling fuck tool were perfectly shaped to slip over him and stimulate him in all the right places. He pushed deep, not stopping until his tip rested against her cervix, then moaned again as he began to thrust in and out. He hands squeezed her breasts harder, twisting and tweaking her hardened nipples with his thumbs as he moved. Leaning forward, he kissed his sister's drooling mouth, playing with her limp tongue, unknowing that she could see him staring into her eyes.

Celestia remained kneeled beside him, enjoying the view of the incestuous joining, his juice slickened cock pushing in and out of her gradually faster. Getting him to do this of his own accord was so much hotter than it would be to force him to do it, though sadly she was sure that he wouldn't agree to murder his sister, not that he'd have a choice.

"Isn't it hot?" Celestia was so close that he could feel her breath on his shaft and balls, "Fucking your own sister's pussy, just like you wanted! But I don't see you going all the way in... come on now... it doesn't count unless you plow that pussy like you mean it!"

He had intended to go easy on her, not wanting her to wake up with too sore a pussy lest she figure out she was used during her nap, but now that he felt that tight wet squeeze around him, it was impossible to resist. He tugged her against him more, and Celestia helpfully reached up to hold her around the waist, keeping her from scooting back as he plowed her. He grasped her breasts hard, squeezing them until he left red marks from his fingers. He pulled his body back to stand against the counter again, and pounded her womb with his shaft, demanding entry.

"That's it!" Celestia encouraged, leaning to Applejack's face and licking up the tears that were flowing freely from her eyes, "Don't stop until your whole man meat is inside!"

That's just what Big Mac did, finally pounding his way through her, groaning loudly in a manner very unlike his usual self, more and more absorbed with the feel of his sibling's pussy. He dragged his fingers down her body to grasp at her hips, pulling them back in time with his thrusts to pound her, his belly now smacking hard against her own as he penetrated her fully. His eyes watched her breasts as they bounced hypnotically from the movements.

Celestia unzipped her pants, allowing her own shaft to flop out into the cool air, moving one hand to stroke herself in time with Big Mac's movements, the other reaching beneath her balls to shove several fingers into her pussy, masturbating furiously with both fuck toys. It might have been enough to shock Big Mac into pausing, if he wasn't too busy to notice that the principal had a shaft that rivaled his own.

"I should... pull out..." murmured Big Mac between heavy breaths, "Don't... think... she's... on... birth... control."

"Oh no you don't," said Celestia, "You blowing it inside is part of our deal, just like in your story. It only counts if you go all the way, otherwise..."

"But... she... might... pregnant..." he panted.

"So what if she does?" Celestia said between licks of Applejack's face, "Isn't that your ultimate fantasy? To knock your own sister up?"

"She'll.. know..." Big Mac complained, yet he certainly didn't stop thrusting.

"We'll claim she went missing for a few hours and then we found her," said Celestia, "If she ends up pregnant, she'll think it's some anonymous rapist... but you'll know the truth... don't you want that? Come on... let me hear how loud you can moan as you impregnate your own sister."

It might have been an awful plan, but Big Mac was far too lost in his own personal fantasy to realize that. He nodded, eyes rolling back and saliva dripping from his mouth onto Applejack's bouncing breasts. Unknown to him, Applejack was panicking inside, trying harder than ever to break the paralysis, wanting to avoid her brother raping a baby into her at all costs. Her body even started to shake violently, her tunnel matching the quiver and massaging hotly around her brother's rape stick.

"Gonna... knock... up... pussy.. fuck..." Big Mac panted out before giving a very loud "Eeeeyup!" as he finally went over.

He had never thought he could have came that hard, but the chance to fuel up his sister's baby making factory threw him over the edge and he hit it like a high diver against a pool of solid cement. He clenched her bottom, his cum erupting inside her, flooding her tunnel and up into her womb, plenty of fertile sperm pushed into her unwilling ovaries. Despite her unwillingness, her pussy exploded as well, milking her brother into her, suckling him dry. He continued to plow her, packing his spunk deeper inside, her belly swelling with the mass of seed as it filled her and then overflowed down his balls and thighs. He didn't stop moaning and thrusting for another good five minutes, riding his orgasm to the end.

Just as he slowed to a stop and looked like he'd pull out, Celestia grinned, "I have a surprise for you."

"Y... ep?" Big Mac panted, moving his hands up to idly massage her breasts once again.

"The drug I gave her didn't actually knock her out," Celestia enlightened him, "It only paralyzed her. She's been completely aware of every second. Every second from when you pulled off her panties to when you raped a load of seed into her."

"N-nope?" Big Macintosh froze, going completely pale.

"Oh I'm not kidding," said Celestia, "You know she's going to kill you when she comes to, or at the very least make sure you spend the rest of your life in prison. The only way you could possibly get out of this... would be to kill her first."

Big Mac stared at Celestia, "Nope!"

"Then I suggest you think of a way to explain to your granny why you decided it was a good reason to knock up your sibling." Celestia grinned.

For a moment Celestia thought he actually might be considering it, but he shook his head again, pulling free of his sister's sopping wet pussy and releasing her breasts, putting both hands to his face.

"I'm sorry..." was all Big Mac could think to say.

Celestia waited patiently. Her magical counterpart had assured her that he would do what she wanted him to do, and that she'd take control of him if she had to to finish the job. He was going to murder Applejack brutally, whether he wanted to or not.
