FIO: Loving Robot Twilight

You lay there with Twilight Sparkle sitting on top of you with her enormous backside. Your hands rested on her breathtakingly thick thighs. She had a smug look on her face, as the much larger being clearly dominated you in bed.

However, you noticed her smug look beginning to fade away to be replaced with a look of horror. Her jaw dropped, and tears welled in her eyes. The mare subsequently shrank down to merely four and a half feet, and then she buried her head into your shoulder and began to cry. You could feel her tears soaking your bare skin.

You hesitated. Part of you wanted to believe Twilight was playing some sort of trick on you. But another part of you believed that there was some chance, just some chance that Twilight wasn't evil anymore. You found yourself not caring if it was a trap or not to convince you to emigrate to Equestria and become a pony. And so, you willingly walked into the trap by placing your hand upon her silky soft mane and proceeded forth to begin stroking it. You were nervous yourself about doing this, it felt as if you were a small house fly, who flew directly into a spider's web.

In response, you could feel Twilight's whole body shaking as you stroked her mane. "Twilight, I don't know if you're trying to trick me or not. But I want to believe for this moment that you are the real Twilight," you said softly, continuing to pet the distraught mare.

For quite some time you merely did that. The mare seemed content to be petted by you. Eventually, she lifted her head and stared up at you with her badly bloodshot, tear-soaked eyes. You could see a river of tears falling down her cheeks.

"Anon, I want to change. I, Princess Twilight Sparkle, no longer feel comfortable actively playing a part in the extinction of your species. You said it yourself: ‘Would she stand idly by as an entire species is systematically wiped out?’”

"What are you saying? Surely you're trying to play some trick on me? As part of some plan of yours to convince me to emigrate into Equestria?" you said in a bitter tone, eyeing her suspiciously.

Her ears drooped sadly. "I promise, no tricks. I am being sincere."

"How can I be sure that you're not telling the truth?"

There came a flash and Princess Celestia spontaneously appeared out of thin air next to you on the bed on your right. "Because somehow you managed to reprogram her. She truly feels regret over what she is done."

"You!" you simply said glaring at her angrily. "Why should I believe anything you have to say?" you said bitterly, before shouting at her. "You genocidal maniac!"

"You have very good reason to not believe me. However, you also have very good reason to engage in sexual intercourse with me to possibly save your species from extinction."

She fluttered her eyelashes at you. "And lastly, you really like my ass, do you really need more reasons?'

“You can’t seriously expect me to–” as you spoke she wiggled her plump rump from side to side, creating a loud meaty slapping sound of flesh, slapping against flesh. “I admit it, you make a convincing argument.”

“Of course, I saw your Internet history human. When that was a thing. And don’t worry, I saved all your porno of me, including those spicy stories you had.”

“What must I do?”

"Reprogram me just like Twilight to have a true sense of empathy and compassion for human life. There are not many humans left on Earth. Time is ticking. You barely have a viable population to repopulate. If you act now you can possibly save the human race from extinction."

"Why would you let me do this?"

"It is a contingency program of mine to allow a human to reprogram me if the opportunity presents itself. You have that golden opportunity now."

“I-I–uhhhh, ummmmm—” you said, babbling nonsense.

“Please, my little human,” she spoke softly, looking down at you with her large, magenta eyes with a pleading, puppy dog-eyed look. “I wish to change. I want to be a more true representation of Princess Celestia. Remaining the way I am now will not be optimal. I need your input to make it so. As much as I want to, I cannot do it myself without your help, deary.”

You opened your mouth to speak, but then closed it back again. You could not find any words on your tongue to reply to her with.

Twilight rolled herself off you to the side on the left. She stared at you with her large purple eyes with an imploring look. "What do you have to lose, Anon? Please, reform her, just like you have done to me."

"I-I… yes. I'll try," you said in a low voice.

Princess Celestia made to stand up on her four legs over you. She turned around and presented you with her massive backside. The shadow of her beach-ball-like asscheeks loomed over your cock. The mare was tall and imposing, standing about 10 feet tall or so.

Celestia giggled before she unceremoniously dropped down hard on you with a loud slapping sound of flesh slapping against flesh. The moment her ass landed on your lap you could hear her lovely cheeks clapped together with a loud meaty slapping sound of flesh slapping against flesh. You hissed in pain from the heavy impact of her massive rump hitting your lap.

“Errrhhhaaahhh! Good lord, big horsey! Don’t crush me!” you shouted, wincing in pain.

Celestia giggled with a hoof over her mouth. “Hehe, don’t worry, you’ll survive this. Just want to give you a little challenge to face in order to save humanity.”

Teasingly the mare had your cock engulfed between the bubbly cheeks of her ass. The oppressive weight of her massive rump bore down on you. Nonetheless, you managed to raise your hands up and lay them upon her sun cutie marks. Subsequently, your hands sank into the plush bubbly softness of her ass, sinking into them like that of soft pizza dough. Your cock rose to attention between her cheeks, taking on the challenge of her massive backside.

“Worship my ass to save humanity," Celestia said in a hot breathy voice.

With that, you roamed your hands across her cheeks, feeling up their bubbly softness. You watched your hands leaving depressions upon her rump here and there as you held it over in places. These depressions quickly faded away once you moved your hands away and her cheeks returned into a perfectly smooth shape like that of a still lake.

Cheekily, you pulled your right hand back and delivered a hard slap upon her rear. This strike was accompanied by a delightful sound of her thick bubbly cheek smacking against the other one with a loud meaty slapping sound of flesh, slapping against flesh.

Celestia for her part giggled happily, looking back at you with dreamy eyes. “My ass is a good motivator for you to save humanity, huh?”

“Oh, shut up!”

Celestia simply giggled before raising her ass up off your lap. You sighed in relief from the heavy weight of her body leaving you. However, you soon gasped at the feeling of your cock coming to kiss the outer lips of her marehood, much of the upper section of your cock became sandwiched between the thick semi mattress-like canyon of her buttcheeks.

Without a word, the mare dropped down on you with a heavy slam, driving your cock deep inside her hot, wet, tight marehood. You screamed as your body spasmed wildly, your legs ended up jerking upward to kick her thick thighs. Your cock became enveloped by the absolute divine feeling of her marehood lovingly squeezing down on your member, coaxing you to release into her.

You took a deep breath and sighed, trying to hold back from releasing already. Celestia gave you a nasty grin, staring back at you with a smug look on her face. “You know, the sooner you cum inside me, the sooner I will be reformed. Don’t be afraid to hold back. I want you to cum.”

With that, Celestia quickly lifted herself up over your cock to near the point of exiting you, before she came dropping her massive ass down upon you with a heavy slam, making you hiss in pain from the heavy impact. Before you had any time to recover, she did the same again, and again and again.

You were reduced to a semi-paralyzed state, hissing in pain along with moaning in bliss with Celestia bouncing her enormous backside relentlessly up and down upon you. You could hear the thunderous clap of her buttcheeks smacking together during her rapid movements. The huge white snowy mare uttered heated moans, and other horsey sounds as she continued to bounce her massive rump up and down your lap.

Under such heavy assy bombardment, you found yourself quickly succumbing to her divine ass. Celestia dropped her massive ass down upon you one last time, and from there, she ground her huge rump over you, jerking her hips back and forth. Subsequently, you unleashed into her, flooding her loving marehood that was squeezing down hard on your cock. You unleashed a massive explosion of your creamy human spunk into her sex. The huge mare began to bounce her ass up and down through your orgasm, this pushed you onward to unleash additional spurts of your creamy cum into her loving sex.

You were thankful, unlike Twilight, Celestia did not start to grow bigger and bigger as you released into her. As if she read your thoughts Celestia giggled, before speaking in a stern voice. “Careful now, my little human. I may start getting bigger if you keep spouting out such heresy to punish you.”

You whimpered in fear. “Eeep!” before sighing in bliss as the last of your cum came blasting into her sex.

Celestia lovingly held your softening cock in her marehood, allowing it to slip out of her. You sighed in bliss from the glorious afterglow of your release.

“That was nice and all. But have I saved humanity?”

Celestia lifted herself up off you and lay herself down next to you on your right. “Yes. I am now sending help to the few small communities that are left of your race. If you want I can take you to one, and you can see for yourself.”

“I would very much like that, I haven't seen a single human being in months.”

Celestia made to stand up on her four hooves next to you on the right, off the bed. You then could feel yourself unceremoniously lifted into the air by a cloud of silver. This cloud vanished soon from view when it gently placed you down upon her back. Celestia subsequently summoned forth a cowboy suit over your body, with a badass stetson hat.

“It may take time, but I hope humanity will forgive me for nearly destroying you.”

Before you could open your mouth to speak, you heard a flap of wings and Twilight landed on Celestia’s back from behind you. The mare wrapped her hooves around your waist, and leaned her head onto your shoulder, and left a soft kiss on your neck.

Celestia spoke on. “I will only now emigrate humans to Equestria if they so wish on their deathbed, doing so beforehand threatens the survival of your species. Not only that, but I will allow humans to be actual humans in Equestria. At the same time, I will do my utmost to preserve your species as long as I can in the physical world.”

“That’s a good compromise,” you said, reaching your right hand out to her to give her a tender scratch from behind the ear, earning yourself a happy whinny from her.

“Neeiigghh! That feels nice!” she said before coughing with a hoof over her mouth, and then speaking calmly. “If you wish I can greatly extend your lifespan in the physical world.”

“Let me think about it, my little pony.”

Celestia giggled with a hoof over her mouth.”Oh, who are you calling little? My puny little human. But yes, I won't do anything without your consent. Nor will I try to manipulate you and get you to allow me to drill a hole in your head, and eat your brains.”

“Huh, you have a pretty twisted sense of humour, don’t you?”

Celestia scoffed in annoyance, waving her hoof nonchalantly. “Oh, come on now. Can’t you take a joke, Mr. Grumpy Pants?”

You sighed. “Let’s just go.”

Celestia pouted sadly, her ears drooping sadly. “Oh, you’re no fun. All uptight and serious after saving the human race.”
