A Beneficial Relationship: A Ponytropolis Thanksgiving Special

Later that day...

Luna and Cinnamon were cuddling in the Kirin’s hut.

“So, that was fun,” Luna said with a light chuckle.

“I have never seen the Kirin engage in a group like that...” Cinnamon cooed, nuzzling the princess’ neck. “And, I am glad that everyone knows about my... little addition...”

“Yes. Now, maybe you will feel more comfortable bathing with the others?”

The Kirin nodded and let out a sigh. "I believe so..."

Suddenly, there was a knocking noise on the hut before they both heard Celestia's voice.

"May I come in?" She asked.

Luna and Cinnamon eyed each other before Luna spoke up. "You may," she called back.

The white alicorn stepped through the curtain and smiled at them. "Hello..."

"Sister..." Luna said with a raised eyebrow. "What can we do for you?"

"Well, it is... more what Cinnamon can do for me..." the white mare said, her eyes falling on the Kirin. "You see, I have been with all the males... and none are as big as she."

The Kirin blushed and eyed Luna, who was eyeing her back. "Does she want me to..."

The blue mare nodded before letting out a chuckle. "Well, I think that is up to Cinnamon," she cooed. "Would you like to show my sister what you can do with your... little friend?"

The Kirin hesitated before looking at the white princess. "Okay," she said with a light smile.

"Fantastic," Celestia said, pulling off her loincloth and tossing it aside before bending over in front of them, showing them her backside. "You may begin when ready."

Cinnamon blushed and eyed Luna before slowly getting to her feet. Looking over the puffy pony princess pussy, she felt her cock start to harden. Removing her loincloth, she stepped up behind the alicorn. Taking hold of her rod, she pressed it up against the pony pussy and slowly pushed it in.

Letting a low moan escape her lips, Celestia panted and looked over her shoulder. "Yes... Push it all in..."

Cinnamon let out a cute gasp as she felt her thighs against the princess' butt. "I-I am... all the way in..."

"Mmm, you are bigger than the boys..." Celestia cooed. "Now, move those hips..."

The Kirin nodded shakily and started moving her hips back and forth. Letting out moans, she gripped the white ass and started speeding up.

"Oh, so eager..." Celestia panted, licking her lips before gazing over at Luna. "Come over here, sister."

Luna raised an eyebrow and got to her feet. "Yes?" She asked, walking around to Celestia's front and kneeling down. "What is it?"

"Get your meat out..." the white alicorn panted. "I need something in my mouth..."

The blue mare went wide-eyed and stood up. "But... sister, we are... well... sisters... We can not do that..."

"Oh, relax..." the white alicorn purred, saliva dripping from her mouth. "You know I am the only one here who could possibly take that whole thing in my throat... And, just look at how wet it is..." She then opened her mouth wide, strings of saliva connecting the top of her mouth to the bottom.

Luna blushed and bit her lip. "I-I suppose so..." she muttered, her horn flashing as her cock grew and hung between her legs. Lifting it up, she held the tip near Celestia's mouth. "Okay... Here I come..." she said, sounding uncertain before she pushed the tip into her sister's mouth. Feeling the wetness surround her cock head, Luna let out a deep moan. "O-Oh, yeah..." She then started to push more and more in until she felt the back of the white mare's throat.

Celestia eyed her and smiled around the cock, before relaxing her throat and jerking her head forward. At feeling the tight throat of the alicorn squeeze her shaft, Luna moaned out and slowly pushed her way deeper and deeper. Cinnamon watched in amazement as she continued to thrust her own hips.

As Luna was about to fully sheathe her cock in her sister’s mouth, the white alicorn stuck her tongue out. Celestia soon felt a nice pair of balls on her tongue, letting out a soft moan at how much bigger they were compared to a Kirin’s.

“So tight...” Luna moaned out, before she started moving her hips back.

She could hear lewd gagging coming from her sister as she pulled back. When she was about half in and half out, she began to slide it back in. She was about to ask her sister if it was too much, but when she looked down she saw a smile on the mare’s face.

As she began to move her hips faster, saliva splattered all over her nuts as some also leaked down the white mare’s chin. It all added up to be a very sloppy deepthroat.

Cinnamon let out louder moans as she neared an orgasm. The spasming pony pussy was a bit much for her and she couldn’t hold back any longer. “I-I am... going to cum...”

The white alicorn smiled and kept licking at the shaft that kept fucking her throat. She soon felt a few spurts of cum in her pussy before her sister moaned out loudly and filled her throat with cum. Coughing, she felt her sister pull out before cum burst from her mouth, dripping down her chin. "Wow, sister..." she said, chuckling lightly before she licked her lips.

"My turn," Luna said, giving her sister a smirk. "Let us switch places..."

"But, I... I just came..." Cinnamon panted.

The blue mare smiled and walked up to her as Celestia stood up and moved to where Luna was. "I can help with that," the blue princess cooed as she cupped the Kirin's balls.

Cinnamon let out a gasp when she felt her rod get hard again. "Huh? How?"

"A little spell I know..." Luna sang, before turning her back to the Kirin and bending over. "Now, put it in."

Cinnamon smiled and felt her full ball sack. She then gripped her cock and aligned it with the princess' dripping marehood. Without hesitation, she pushed her way in with a moan. As she began moving her hips and gripping the ass tightly, the alicorn let out moans of her own.

Luna was suddenly greeted by something long and white... with a pair of balls. Looking up, she saw her sister smiling down at her. "I-I do not... think I can fit that... in my mouth l-like you can, sister..."

"Then, lick it," the white alicorn cooed, holding the base of her rod and rubbing her sister's face with the shaft. "Come on..."

The blue mare rolled her eyes before sticking out her tongue to lick the long piece of meat. She could hear her sister moan before the white mare suddenly stepped forward, lifting her cock and pressing her nuts to Luna's face. Getting a huge of the mare balls, Luna blushed before resuming her licking.

As the blue mare licked at the balls, Celestia stroked her long horse cock with both hands. "Mmm... This feels nice..." she moaned, before biting her lip and stroking a little faster.

Cinnamon could feel a little bit of cum leak out from her dick, telling her she was close. "I am... almost there... again..."

Luna let out a louder moan at hearing her Kirin lover was about to shoot her tiny load into her. Burying her face into her sister's sack like a pillow, she let out a muffled moan as her pussy squirted some juices onto the Kirin's crotch and balls. The sudden burst of mare cum made Cinnamon thrust in deeply before cumming. Celestia panted at hearing both of them have their orgasm, speeding up her jerking before her cock began to spray cum all over her sister's back. Some even landed on Cinnamon's face.

No one had a single second to rest when there was a knock on the outside of the hut.

"Y-You having fun in there?" Came Autumn's voice. "Can I join?"

Celestia, Luna, and Cinnamon all eyed each other before Luna looked at the entrance.

"Come on in," the blue mare said.

Autumn quickly entered and closed the curtain, coming to a halt when seeing the aftermath. "Wow... That looks like fun," she said with a wide smile. "Can it be my turn in the middle?"

Luna nodded and stood up, cum dripping down her back. "Of course," she said, using her spell on Cinnamon's balls again before joining her sister. Autumn then threw her loincloth to the side and took her spot in the middle.

The Kirin then turned her back to Cinnamon and looked over her shoulder. "Show me what you can do..." she said, getting a smile and a blush from the red Kirin. Bending over, she stuck her ass out and looked up at the two princesses. “Feel free to stick those in my face all you want.”

“Oh, we were planning on it,” Luna said with a chuckle, stepping closer and pressing her shaft to the Kirin’s face.

Celestia did the same, both their dicks pressing together as they shoved them in Autumn’s face.

“Oh, they actually feel nice pressed together,” Luna pointed out. “I can feel you throbbing against me.”

“Same,” Celestia cooed, eyeing Cinnamon as she began to move her hips. Celestia then looked at Luna. “Makes me wonder... what else we can do together...”

Luna blushed at this. “Uh... What?” She asked, shocked by her sister’s incestuous idea.

“We are both immortal, sister,” Celestia reminded her as Autumn started licking the white cock. “We can not spend all our time here as we have a kingdom to rule... and we can not ask our guards or subjects as it would ruin our image. It is the best option...”

Luna thought for a moment before letting out a chuckle. “Well... you are right... again... And, to celebrate this revelation..." she added, before reaching to the back of Celestia's head and pulling her into a kiss.

Cinnamon watched the two sisters make out as she kept thrusting into the fun-loving Kirin. Celestia and Luna soon broke the kiss and smiled at each other. As they looked into each other's eyes, Autumn gave both cocks one more lick before looking up at them.

"I would like to switch it up," she said with a wide smile.

"Already?" Luna asked, raising an eyebrow in confusion.

"I'm getting close and I wanna feel your thick pole in me before I cum," Autumn explained.

"B-But, I... I am not..." Cinnamon started to whine.

Eyeing the red Kirin, Luna nodded. "My sister can finish up with your mouth..." she said, running her hand over Autumn's body as she made her way towards Cinnamon. "I will finish in your wet... pussy..." She then smiled at Cinnamon. "You can finish in my butt, okay, sweetie?"

Cinnamon smiled back and nodded, pulling out of Autumn and taking a step back. Luna slid in between them and lifted her cock so that the tip pressed to the Kirin's wet folds. With a light jerk, she pushed the tip in and got a loud gasp from Autumn. Smirking, Luna continued to go deeper and deeper. When she felt the entrance to the womb, she began to shorten her cock until her hips touched the Kirin ass.

"How are you holding out so far?" Luna cooed.

"I-It's so... big..." Autumn moaned, her face resting on Celestia's balls.

Luna chuckled and began to slowly move her hips. "You can start when you are ready, Cinnamon..."

The red Kirin nodded and aligned her cock with the princess' ass before pushing in. Letting out a grunt, Luna closed her eyes and smiled. As she moved her hips to fuck the Kirin, her ass also slid back and forth along the other Kirin's rod. Celestia smiled as she watched them, her left hand resting on Autumn's head.

It wasn't much longer before Autumn let out a loud moan and squirted her juices onto Luna's nuts. At the same time, Luna let out a loud moan and began to empty her balls. As cum spurted back out after the Kirin pussy was full, Cinnamon began to dump her small load inside the alicorn's butt.

Luna moaned at having her sack emptied and having her ass fill up at the same time. "Mmm... That was amazing..." she cooed.

Cinnamon smiled and wrapped her arms around the alicorn. "It sure was..."

Autumn got to her hands and knees, sliding off the princess dick and causing a ton of cum to pour out. "Oh, my gooooooooooood..." she moaned deeply, creating a large puddle beneath her before collapsing.

Celestia chuckled and looked up at Luna. "I think she enjoyed that. I suppose she will be here for a bit while she recovers..."

"We do not mind," Luna replied with a smile.

"Not at all," Cinnamon added. "She is more than welcome to spend the night if she has to."

Celestia nodded and went to get her loincloth. "I will see you two later. I want to spend the night with Rain Shine again."

Luna smirked and watched her sister. "You like her, do you not?"

The white mare finished getting dressed and smiled. "About as much as you like Cinnamon..." she said, giving them both a wink before leaving.

The blue alicorn turned to face the red Kirin and kissed her on the lips. "How about we relax and recover?"

"Sounds good..." Cinnamon said, eyes half-lidded.

The two then got to the floor next to Autumn and cuddled.
