The Chapter

Pinkie Pie trotted through town with a smile one her muzzle. To most this was a common sight, but today was a bit different. You would never know it, just looking at her wouldn’t tell you, nor would talking to her. Perhaps if you looked at how she walked you might get an idea, but it’s still not likely. Even if you could see her aura you still would have a hard time noticing it. Pinkie waved to everyone as usual, giving her usual greetings and popping out from behind a set of barrels to greet a pony who was resting against them.

It was a Monday, Pinkie’s day off, and she was off to spend some time with her friends. She had stopped by Rarity’s, Rainbow’s, Fluttershy’s and Applejack’s places but they were all busy, so she was headed to Twilight’s library. Pinkie hopped along the path that led to the library humming a cheery tune. She hopped her way through the door and up to Twilight’s room, where the purple mare was busy reading. Pinkie bounced her way over to Twilight, who was facing the other way. “Heya Twilight, whatcha reading?”

Twilight jumped a bit and the book she was reading went flying into the air. “Ahh!” Twilight screamed as she turned to face the source of the sound, she immediately calmed down when she saw who it was, “Pinkie, Please don’t do that again, you almost gave me a heart attack.”

“Sorry Twilight, I just wanted to surprise you with a visit,” Pinkie said, feeling a bit bad for startling Twilight.

“It’s-” Twilight started before the book that she had accidentally tossed into the air came slamming down on her rear which caused her to jump again. Twilight whipped around to see what happened and found the book sitting off to the side of her rump. She shook her head and turned back to Pinkie “as I was saying, it’s okay. Though how did you get in here?”

“Through the front door.” Pinkie said as she bounced onto the bed and sat next to Twilight.

“Oh…” Twilight said before murmuring, “Could have sworn I locked it.”

“So, what are you reading?” Pinkie asked as she looked at the book. She was a bit surprised to see that it was a romance novel. “I didn’t think you read these kinds of novels Twi.”

“I-um, enjoy them from time to time,” Twilight said, a harsh blush spreading across her muzzle.

“Cool, what’s it about?” Pinkie asked, oblivious to Twilight’s embarrassment. She looked at the page Twilight was on and gasped. The passage described a mare who risked herself to save the love of her life, her longtime friend, who was also a mare. “I never knew you were into mares Twi.”

Twilight’s blush intensified, “Yeah… I uh, I always have been a bit shy about it.”

“There’s nothing wrong with liking mares Twi, I like them too.” Pinkie said as she lay down next to Twilight and rubbed herself against her. Pinkie gave Twilight a gentle nuzzle, “would you like me to help you with that itch?”

Twilight’s blush intensified, “Is it that obvious?”

“Mmm hmm,” Pinkie replied as she gave Twi another nuzzle. “I would be glad to ‘help’ you with your needs, in any way you wanted.”

Pinkie licked one of Twilight’s ears before nibbling on it. The sensation of Pinkie nibbling on her ears made Twilight moan. Twilight gave another moan as her cunt started to get wet. Pinkie used her tail to rub Twilight’s cunt, which got a louder moan out of Twilight. Pinkie continued her efforts driving Twilight closer and close to her climax. She could tell that Twilight was close and rolled Twilight onto her back. Pinkie dove in and started licking Twilight’s cunt.

This was enough to take Twilight over the edge. Twilight gripped Pinkie’s head with her hind legs as she came. Her juices spraying into Pinkie’s mouth and all over Pinkie’s face. This caused something in Twilight to snap. When her orgasm finished Twilight pulled Pinkie on top of her with her magic and kissed Pinkie full on, on the muzzle. Pinkie returned the kiss and sipped her tongue into Twi’s mouth. Their tongues wrestled as they kissed, but eventually they broke apart for air. “Pinkie,” Twilight panted, “that was awesome.”

“It sure was,” Pinkie replied as she snuggled closer to Twilight. “You up for more?”

“Yeah,” Twilight said as she nuzzled Pinkie, “I was thinking. There is something that I would like to try, but…” Twilight looked away, a blush spreading across her muzzle.

“C’mon Twi, you can tell me.” Pinkie encouraged as she licked Twilight’s neck.

“I… I want to… I want to do something that you may find disgusting, it’s something that I have always wanted to do, but I- I never had the courage to do,” Twilight whispered as Pinkie wrapped her hooves around her.

“Just tell me Twi,” Pinkie said into her ear, her soft tone reassuring Twilight.

“I want to- to use your mouth like a toilet. I want to fill it with my feces and urine.” Twilight said with a whimper, as she looked away in shame.

Pinkie pulled Twilight closer to her, “It’s okay Twilight, ponies like strange things, and to be honest, I don’t mind.”

“You don’t?” Twilight gasped as she turned to look at Pinkie.

“Nope, I don’t mind one bit. I would be glad to try it.” Pinkie said with a smile before giving Twilight a peck on the lips.

“R-really?” Twilight asked, “You would do that for me?”

“Yeah,” Pinkie whispered as she pulled Twilight closer, “you mean a lot to me, Twilight, and I want to make you happy.”

“I… thank you Pinkie,” Twilight whispered as she enjoyed the feeling of Pinkie’s closeness.

After a while of cuddling Pinkie spoke up, “So, Twi, how are we going to do this?”

“Hmm?”

“How are we going to experience this fetish?” Pinkie asked as she loosened her grip on Twilight.

“Well, I can easily sit on your muzzle while you’re on your back.” Twilight suggested as she started to get up. Pinkie rolled onto her back and laid perfectly still.

“I’m ready when you are Twi,” Pinkie said as the purple alicorn moved over to her.

Twilight blushed a bit, before straddling Pinkie’s muzzle. Twilight sat her cunt on Pinkie’s lips and immediately felt Pinkie open her mouth. Twilight felt Pinkie’s tongue giving her cunt a teasing lick, encouraging her to release her golden waters. Twilight relaxed and gave a sigh of relief as she started to pee.

Pinkie could taste the salty and bitter fluid as it started to fill her mouth. She savored the unique taste before swallowing some of Twilight’s golden pee. She could feel the strong spray of it hitting the back of her mouth as her mouth started to fill again. Pinkie quickly started gulping down the delicious juice that Twilight was giving her. Though it came to the end too soon for her liking, the stream of urine slowed down and soon it stopped, but Pinkie still had a mouth full of pee. She sat there for a bit and enjoyed the unique flavor, letting it rest in her mouth, she was able to fully taste it. It was unlike anything she had tasted before. The salt and bitterness were accompanied with a sweetness that was almost completely masked by sourness.

Pinkie slowly swallowed the last of the pee, enjoying it as it went down. “Twi, that was awesome.”

“Was it really that good?” Twilight asked as she looked down at the pink pony.

“Mmm hmm,” Pinkie said as she gave Twilight’s cunt a few licks so that she could clean off the last of the pee, which got a moan out of Twilight, “in fact, I would like to do it again sometime, but now we can get onto the other one that you wanted to try.”

“Are you sure Pinkie? I mean… I hear that everypony that tries it pukes on the first time.” Twilight said. She was concerned for Pinkie, and didn’t want her to get sick.

“I’m sure Twi. I’ll be fine.” Pinkie said with a smile.

“Okay,” Twilight responded before shifting herself so that her plot hole was over Pinkie’s muzzle. Again Twilight could feel Pinkie giving her an encouraging lick, and this time she started pushing. Twilight gave a strong push and a small jet of her pee sprayed out and onto Pinkie’s chest. Twilight kept pushing and soon there was a little harrumph as a small fart escaped her plot hole.

Pinkie could feel the hot air from the fart filling up her mouth, and she happily inhaled it. Soon she felt Twilight’s anus expanding. As Pinkie licked Twilight’s plot hole she could taste the first piece of poop. Soon that piece of poop fell into her mouth and she started chewing. The taste was strange to say the least. It was earthy, bitter and sour but she liked it. The texture was mushy, like a paste, and stuck to her teeth and the roof of her mouth. She swallowed the first one and licked what remained off the top of her mouth.

Soon Twilight released a second horse-apple into Pinkie's mouth. Pinkie enjoyed it just as much, if not more, than the first one. She chewed the mushy, pasty, poop and savored it. Instead of feeling sick she was enjoying it, the feeling of serving her friend in such an intimate way really turned her on. As Twilight pushed another one into her mouth she felt something different, it was a liquid warmth on her chest. Twilight was peeing on her as she ate the shit in her mouth. The combined feeling of the warmth on her chest and the shit in her mouth made her lose control. Her pussy lips spread a bit and she started to pee on Twilight’s bed. She felt so ashamed for peeing all over her friend’s bed, but she didn’t have time to reflect as another piece of shit landed in her mouth. Pinkie continued to eat her friend’s shit as she peed all over the bed. The very sensation of eating her friend’s poop while pissing was nearly orgasmic.

As Twilight finished emptying her bowels into Pinkie’s mouth she reached over to Pinkie’s cunt and started to rub it. In no time at all, Pinkie came all over Twilight’s hoof. Twilight moved back so that she was sitting with her plot hole on Pinkie’s lips and licked the love juices off of her hoof. The taste alone drove her wild. Twilight soon finished her treat and she could feel Pinkie licking the remains of her feces off of her plot. Twilight got off of Pinkie and laid next to her.

“I’m sorry Twilight. I peed all over your bed.” Pinkie said as she looked away in shame.

“It’s fine, Pinkie,” Twilight said as brought Pinkie’s muzzle back to face her, “I would have urinated and defecated on it if you weren’t here.”

“Thanks Twi,” Pinkie said as she nuzzled Twilight.

“It’s me who should be thanking you, you let me live out my deepest fantasy,” Twilight said as she kissed Pinkie.

“I would like to do that again Twilight.” Pinkie said, a blush crossing her face.

“I would like that Pinkie,” Twilight said as she licked Pinkie on the muzzle.

“Twilight, do… do you think we could ever have something stable?” Pinkie asked as she looked Twilight in the eyes.

“Maybe, but let’s save that for tomorrow and get some rest now,” Twilight wrapped her hooves around Pinkie and pulled her close. Soon they were asleep, happy in each other’s embrace.
