Polyamory

Even now, Twilight’s mind searched for some reason that this was part of Chrysalis’ evil plan, but she found none. Chrysalis had proven that she was nicer than Twilight thought and that she could conquer Equestria on a whim in the same night. That was a feat that Twilight never expected to witness.

Twilight couldn’t stay enemies with her brother’s new wife, but being friends with her wouldn’t be easy. It’d be even harder than it was with Discord, since he was only banging one of Twilight’s friends, not marrying a family member… and a mentor.

Twilight just wanted to get to her room. She was so pent up now that she was leaving a drippy trail behind her. Night had been nice enough to escort her back to her room in the palace, but she could sense his eyes on her plot as he insisted on walking behind her.

“Um, Twilight, dear,” Night said from behind her as they headed up the staircase in the tower she was staying in. “I think there’s something I should tell you.”

“Apparently there’s a lot I need told,” sighed Twilight, but smiled back at him all the same. “Sorry. Is there something else I need to learn tonight?”

“Well,” Night chuckled awkwardly. “It may or may not have been my idea… this whole thing.”

Twilight stopped and turned to stare at her father.

“Well I meant it to be purely playful,” Night backtracked. “But the idea came from some comments I made to Princess Chrysalis.”

“Please don’t call her that, yet at least,” grumbled Twilight, but luckily for Night, she was more amused than angry. “What comments were those?”

“How I’d like some time with you,” Night blushed. She’d never seen him blush at all. “The idea may have been to get you riled up so that you’d be willing to… spend some erotic time with your old stallion. Creepy… I know.”

Twilight stared at him. Thinking back on how he’d been eyeing her the whole time, it shouldn’t have surprised her. Night cleared his throat when she didn’t answer, taking an awkward step backward.

“It’s not… creepy,” shrugged Twilight. “Sorry I disappointed you. It was just a bit much, in front of everypony.”

“Well, we wouldn’t be in front of anypony if we did it now,” Night grinned, then took another step back when she didn’t answer.

Twilight closed her eyes, taking a deep breath. She was definitely pent because she wanted nothing more than to tackle her father onto the floor right here in the stairwell.

“Sorry, sweetheart,” Night Light patted her cheek, then turned to head off. “I’ll leave you be.”

He didn’t even get to turn all the way around before Twilight’s horn glowed, grabbing him by one hind leg and dragging him back to her. She licked her lips as she flipped him over roughly, letting him fall back-down onto the floor. Sure, she didn’t need to rough him up, but she knew he’d love it.

“Sweet Celestia’s heavenly cunt honey, yes,” Night almost squealed. “You are so like your mother… this is almost just like when she conceived you… well not exactly… it was under a table in a library, not in a castle stairwell, but she flipped my plot over just like you did!”

“Less stories, more fucking,” Twilight panted, far too riled up for that. It figured she was made in a library though.

Twilight yanked his legs apart, placing her nose against his ball sack and licking across his sheath. He was already hard, so she ran it in loops around his shaft. It could have been her hormone-drenched blood talking, but she had never tasted anything so delicious. She slid up his body, lapping all the way across his belly up to his neck before settling her drooling slit against the throbbing member that had one bucked her into existence.

Twilight moved as fast as she could before she lost her nerve, pushing his blunt tip against her tight entrance and sitting hard. She moaned loud enough to echo through the stairwell as he stretched her out, lips gliding over his warm flesh, popping over his thick ridge, and smacking his belly as his daughter forced him balls deep inside her. It was the closest thing to Shining’s cock she’d ever had in her, so she couldn’t help but wonder how similar it felt.

“Don’t dare get off until I’m done,” Twilight groaned as she bounced atop him, a puddle of her cream already wetting his belly.

“Yes ma’am!” Night grinned, loving every bit of his daughter’s aggressiveness. “Believe me, Daddy knows his place!”

All the same, he didn’t sound confident in his ability to do so with the convulsions rocking over him from her insanely aroused tunnel. He couldn’t get off faster than Twilight though, given that she popped in a few thrusts. Her bliss flooded over him onto the floor, but she still wasn’t done, continuing to slam her body down even as her sensitivity rose.

Twilight growled as she leaned down and kissed Night, grasping their forelegs together and pulling closer. They explored each other’s muzzles and coated each other’s faces in slobber as they continued to make out. Both their groans rattled the stairwell, neither holding back because anypony in the castle might hear them. It wasn’t like this sort of activity wasn’t the norm in Canterlot Castle now. Even the incest part was getting pretty mundane.

“I can’t hold it much longer…” Night panted. His shaft pulsed so violently that she felt like it might explode, already coating her tunnel with a coat of pre. “Please tell me you’re not on foal control.”

“I’m not on foal control,” confirmed Twilight, but then her eyes widened. “Shit! I’m not on foal control!”

Twilight’s horn glowed as she cast a spell on herself to keep her from giving birth to her own sibling, assuming nothing had already gotten through. It wasn’t that the idea of bearing her father’s foal was offensive in her current mood, and more that she’d rather give birth to her own nibling with Shining. Wait, did she really just think that?

“Guess I shouldn’t have asked…” Night groaned, but still went off so hard that he blacked out for a moment. He shivered violently in a seizure of pleasure as he blasted Twilight full of warmth until her belly swelled with his seed.

Twilight kept rolling her hips, feeling his daddy’s spunk sloshing around inside her, and soon creamed herself again as well. She squealed as she added to the puddle of juice that was now dribbling down the stairs next to them.

As she came down from her sudden sex high, Night took her head gently in both front hooves and kissed her once more gently on the muzzle.

“I hope you know how much I love you, sweetheart,” Night panted.

“I love you too, Daddy,” Twilight smiled.

“Aw… that’s so sweet!” a familiar voice spoke.

“That’s the same gift I gave for last Father’s Day!” a nearly exact voice responded.

Twilight jerked, looking around to find that their noise had earned them an audience, to the tune of half a dozen changelings, several palace guards, and two Pinkie Pies, who were passing a bag of popcorn back and forth. It was the Pinkies that had spoken, though Twilight had no idea which was Pinkie and which was Pinkie’s favorite changeling.

Twilight was out of energy for screaming, so she just sighed, “Pinkie…” She smiled, standing up on wobbling legs as her father’s schlong slurped out of her drooling slit, and blushed as she made her way back to her room.

Tomorrow would be long, but at least Twilight knew it wouldn’t be a complete disaster now.
