Chapter 1: The set up.
Pinkie had walked into Carousel Boutique with Rarity, Rainbow Dash, Applejack, Fluttershy, and Twilight, with only her being happy about tonight's Nightmare Night party. Since you were being invited to it. "Out of all the girls we could've gone with, why her Pinkie?" Rarity asked in frustration, she didn't hate you. But she wasn't sure if she wanted to have sex with a human of all things.
"Because we never had a Nightmare Night with her silly, and she seems to always be at home for the entire time. So I invited her with us, so we can have fun." Pinkie said innocently, vouching for you as best she could. She wasn't aware of a fertility problem you had on this night, but she didn't know much on humans either.
"Ah recon she's just nervous on Naghtmare Naght, Ah never see her until she's at ma farm fer her apples." AJ said in honest suspicion, trying to put the puzzle of your odd behavior together the best she could.
"W-Well... Sh-She attends my animals with me at the start of the day, b-but when I b-bring up Angel's c-carrot... Sh-She blushes m-more than Rarity." Fluttershy says as she explains her angle on your behavior, while stuttering out of shyness. "N-No offense Rarity."
"None taken Darling, after all... Anon isn't Blueblood, so we can focus on her more than me." Rarity said, not even offended at her own friend saying her blush was being out-done by you.
"This is bullshit, she never hangs out with us during Nightmare Night of all things. Either she's a spy, or she's hiding something from us." Rainbow said rudely, getting more angry at the fact that you seem more closed off than she'd care to let slide under her wings.
"My bet's on human biology going against her, she's always avoiding my scientific question on human sexual reproduction. Maybe she's a virgin, or at the very least.... Fertile on Nightmare Night." Twilight interjected, getting the attention of all of the group, minus Pinkie, interested in her thoughts on your oddly specific closed off behavior.
"So... She's scared of being knocked up? That's it?" Rainbow spoke up, before scoffing in disbelief. "As if Twi, we all get fertile. But I just don't give a damn on who's knocking me up."
"Ah'm with Rainbow on that one, does getting banged really sound like a bad thing? From what Ah can tell, she needs a good fuckin' more than Fluttershy." AJ said, agreeing with her tomboyish friend.
"I agree as well Darling, she even told me about an awful break up she had with some ruffian named 'Brad' back on earth." Rarity joined in, remembering a private girl talk you both had on Hearts and Hooves day.
"So it's settled, we're gonna bond with Anon one way.... Through a game of paternity roulette." Rainbow declared with confidence, and everypony, minus Pinkie, who was dressing her pet baby gator up in a tuxedo, agreed with a simple nod.
"We gotta pop a bun in her oven, her tam in her house been screwin with her head fer long enough." AJ said in the equal amount of confidence as the cyan pegasus, tipping her hat in the process.
"Then let's pick a good place to start. The library is an obvious no-go, since she might get suspicious of me." Twilight said as she used her logic to narrow down their possible location of the sex game.
"I'd suggest my boutique, but I'm afraid that she'd have more places to hide." Rarity says as she rules out her own home.
"She can't fly, so Cloudsdale is off the table." Rainbow said as she ruled out her favorite place of competition.
"What about Sugarcube Corner? She's most offen gettin a sweet er two from there, and she likes Pinkie's sweets." AJ suggested, stating what she's been noticing in your schedule.
"That might just work. Applejack, you're a genius!" Twilight exclaimed in excitement, proud to hear the possible location of their game of paternity roulette. "Now all we need is some nylon rope, and a way to have her meet us there without getting suspicious."
"The nylon rope, I can handle Twilight. But I believe Pinkie might be able to bring her to us." Rarity said as she snapped her fingers to get the party mare's attention.
To which Pinkie put Gumpy down gently, and nodded enthusiastically. Not even sure what her friends were talking about, she stayed silent and hope somepony could explain what was going on to her. "I've got it!" Rainbow Dash said suddenly, getting the attention of the entire group. "The invite could be our cover, and we could make up some excuse to drop her guard... And we pounce on her, tie the bitch up, and fuck her until she's bloated with our cum."
"Rainbow, that's possibly the best thing I've heard in my life!" Twilight said with excitement shown plain as day, bouncing more and more with little bursts of giggling. She never believed she'd get the chance to experience your clitoris, but now she had hope to not only see it. But also feel it with her marecock. "Pinkie, did you send the invite yet?" She asked as she turned to the pink party pony, only to see her shake her head back and forth. "Then do it, we'll get everything ready for our 'guest' to arrive."
Meanwhile with you.
You were reading another Daring Do book with the CMC, on chapter 16; the lost treasure of Discord. "... And then she saw it, the lost city of Disharmony. The ancient city of the draconequus race." Just as you got halfway through the beginning paragraph, a timer rang. Signaling it was time for you to leave. 'Damn it, just when I got right to the good part to.' You think in your own head as you closed the Daring Do book that Apple Bloom picked out for you to read. "Looks like the rest will have to wait until next time girls." You said as you handed the book back to the small yellow earth pony, before petting her mane in appreciation.
"Wow Anon. You love telling stories, don't you?" Said Scootaloo, the small pegasus that was more adventurous than the others in the group. She always looked up to Rainbow Dash like the sister she was, but now she was spending more time with you since humans were awesome in her mind.
"Yeah I do, I was actually planning on becoming a writer before leaving Earth." You told the small orange pegasus out of sheer honesty, gladly telling her about your future career in book writing.
