Set in the middle of The Fall, during James' birthday celebrations.

_

Lauren was shattered after the adrenaline-fuelled go-karting, which they were doing to celebrate James' 15th birthday. But at least now, after a hot shower probably exceeding the melting point of steel, she was cosy and relaxed. She was lying on a soft bed in her room which was just a bit better than her one on campus. Bethany was in the shower and Lauren could see the steam curling up from under the door.

Her mind wandered to Bethany and her body, and how it felt. Lauren and Bethany had known each other were bisexual for a while, but no one else knew. Not even Rat, Lauren's boyfriend. This relationship truly was top-secret, and Lauren had already done 'things' with Bethany. Bethany had a fetish which she'd revealed to Lauren already, and while Lauren didn't share it she was more than happy to do what her friend wanted. Lauren also had a fetish, but this was one which Bethany didn't know about. Until now.

Lauren opened the unlocked bathroom door. Bethany turned off the shower, and saw it was Lauren.

"Can't you see I'm showering here?" She giggled.

"Yes, but I had a thought..."

"Go on."

"You know how you like feet? Well, I have a fetish of my own. I like shit."

The look on Bethany's face was one of surprise, but not disgust. This made Lauren a bit more confident.

"Yeah, uh, I have a scat fetish. I want to try it out sometime. That's all I had to say."

"I haven't met anyone with a scat fetish before, and I haven't really thought of it. But I'll do anything once..." Bethany said, her words measured.

"Really? You would?" Said Lauren anticipatingly.

"Yeah, for sure. And if I like it, maybe we can do it again!" Bethany said, with a wink.

"Well... do you want to do it now?" Lauren asked.

"I did have a lot of food yesterday. I think it's about done cooking."

"Well doesn't that just sound delicious!" Squealed Lauren happily, as she moved to place her head on the toilet.

Head back, she could see Bethany's plump-but-not-fat behind reverse into view, like a garbage truck about to dump its contents. Lauren could see the dark patch of skin around Beth's puckered asshole, with a dusting of recently grown hair surrounding the area. Bethany's arse kept growing in size until it almost filled Lauren's view. Lauren could see every detail, like how smooth her cheeks were, and how the ring itself was just a tinge lighter than the darkened skin in the valley. She could also smell the stale scent of dried shit, though she could see none.

Bethany was not very tall, so she didn't need to squat much to gently place her hole on Lauren's nose. She didn't want to sit down or put too much weight on Lauren's head, otherwise it might hurt her.

Lauren could feel the fine hairs tickling her nose, the warmth of Bethany's body and the squirming of her muscles inside. She could smell Bethany's musk, and wondered when she had last taken a shit. Lauren tried to push her nose deeper, but her soft nose just bent down. So instead she began to nuzzle the soft and sensitive area. Bethany felt this and responded with a giggle, before letting out a small trumpeting fart. It only had a light smell, and the vibrations of Bethany's asshole were wonderful against Lauren's nose. Bethany shuffled back, until her pussy, also with a light dusting of dark hair, was sitting softly over Lauren's mouth. Lauren poked her tongue up and gave a little lick. Gradually she gave bigger licks, building up. Bethany began to make a quiet but reassuring moaning sound, which told Lauren she was doing the right thing. After a minute of this, Bethany interrupted the tongue massage.

"Here it comes!" She said excitedly.

Lauren felt a wetness spread across her face, and she opened her mouth as the stream of Bethany's pee got stronger. Lauren's mouth was filled quickly with the bitter tasting fluid, and she hurriedly began to gulp it down as some began to overflow from the sides of her mouth, into the toilet. Bethany's piss was hot and bitter, and Lauren could taste that she had had quite a bit of the sparkling wine Kyle bought. Nevertheless, Lauren kept at it, trying to fight the stream as it flowed into the puddle that was Lauren's mouth. Suddenly Lauren took a gulp at the wrong moment, and broke out into a coughing fit. Her head rocked back and forth against Bethany. This took Bethany by surprise and she cut off the stream before it could finish properly. She looked down to see her friend recovering, and yellow pee over the toilet seat and a little bit of the surrounding floor. But it wasn't bad, nothing that couldn't be cleaned up at the end. Lauren began to laugh at what she'd done, and Bethany joined in as well. After a moment of cackling, both girls fixed eyes with each other and smiled. Bethany turned around so that this time her front was facing the toilet and Lauren, which would make it easier for her to drink Bethany's piss. Bethany shuffled right up to place her soft vagina against Lauren's lips, and the stream resumed. Lauren was on the ball this time and swallowed quickly, with no overflow. Shortly after starting, the stream died down and cut out. Lauren gave Bethany's snatch another lick, this time with a bitter and salty taste, mixed with a tinge of alcohol.

"So, are you ready for part two?" Asked Bethany.

"Yes! Let's do this!" Lauren replied enthusiastically.

Bethany stepped away and turned around. She moved back to assume the position they had earlier, where her dark asshole was sitting on Lauren's nose. Bethany, however, didn't want the destination to be Lauren's nose, and so she shuffled forward to bring her asshole to rest on Lauren's wet and close lips. Lauren could feel Bethany pushing and pulling inside, and so she stuck out her tongue to get a taste of that beautiful young asshole. She could taste the stale taste of shit, and sweat despite Bethany coming out the shower ten minutes ago. Lauren continued to work her tongue in the crooks and crannies, savouring every last taste. Suddenly, Bethany's brown hole made a high-pitched whine, a bit like a balloon deflating, as the load approached the exit. Lauren now tried to push her tongue inside Bethany, instead of going over the surface. Bethany's ring was closed tight, but it loosened momentarily and Lauren was able to get some of her tongue inside. She poked around, feeling the soft walls of Bethany's rectum, as well as some small deposits of poop. Then Lauren's tongue glided over what she was looking for - she moved her tongue back to feel a soft but firm turd, moving along slowly. It tasted almost sweet, which could have been from all the sweeteners of today and the day before. Bethany was moaning in the background as Lauren explored Bethany's rectum with her tongue. After a minute of poking around, Lauren pulled out her tongue to let Bethany's turd come out. It took a moment but Lauren saw her hole open up and begin to widen as the turd approached. The ring didn't open up to a massive diameter but it was by no means a small poop. Lauren watched as the head of the firm, smooth log slid out of Bethany's poop chute. It took Lauren a moment to remember that she wanted this, so she opened her mouth to receive the turd in all its glory. Bethany kept pushing out her waste as it entered Lauren's mouth and settled at the back. It curled around inside and began to build up. Bethany was grunting as she pushed it out. She could also smell it in all its glory, as could Lauren. The turd began to eat softer and less firm as it came out. Lauren's mouth was almost full with the dark brown cable, and Bethany still had more to come. The poo had originally been firm, but now it was coming out all soft like ice cream. It had also changed colour from being very dark brown to being more greenish-brown. The original turd had been sweet and you could almost begin to describe it as tasty, but Lauren had experience with her own and knew that she was right when she though that the soft-served poop coming out now would not be sweet at all. At least she couldn't taste it with the earlier shit on her tongue. Lauren had not been swallowing any of the shit, instead letting it pile up in her mouth. Lauren switched her thoughts back to reality. She could see the poo beginning to thin as it came out, and soon enough Bethany cut it and the end curled over almost comically. Bethany stood up from her light squatting position, and the stretched over to touch her toes. As she did she let out a massive fart, which would have put her brother Jake, the ultimate farter, to shame. Bethany laughed as she got up and turned around to see Lauren. As she saw her, she gasped and put a hand over her mouth. Lauren could make out a muffled 'Oh my God'.

The pile of shit in Lauren's mouth was a few inches high above her mouth. Bethany's load stank, and it looked the part too. Many thoughts raced through Bethany's mind, some wondering how Lauren would want to be so depraved, and some thinking how it was actually pretty hot.

"My best friend, with a pile of my stinking shit in her mouth..."

"Hold on... I know!" Bethany thought aloud.

She briskly walked out the bathroom, her asshole still shitty, and grabbed her mobile from the table. She went back and lined up a shot of Lauren with the mess in her mouth. Lauren looked slightly afraid, but Bethany attempted to reassure her with the promise that it's 'just for a memory'. Lauren was okay with that.

"And guess what, Lauren? I still have more to come!" Said Bethany with a smirk.

Lauren guessed that Bethany was just a natural dominator. Lauren didn't particularly mind where she was for either sex or fetish play, but it was evident that Bethany played her top role well. Lauren tried to give a smile, but it's difficult with your head back on a toilet seat and a pile of shit in your mouth. Bethany motioned for Lauren to lie down on the floor, and Lauren complied. Bethany came over and squatted over Lauren's face again, except this time Bethany pushed her ass down on top of Lauren's face. Bethany pushed down and rubbed her bum on Lauren's face, and after a minute of this she stopped and got up. She could feel the sticky coating of shit on her bum, and saw that Lauren now had a face streaked with Bethany's excrement. The previously tall pile of shit was now just a mouthful, with the rest of it either on Bethany's dirty ass or Lauren's face.

"Now... I think you should swallow it?" Bethany said uncertainly.

Lauren nodded and began to try to swallow the load. Bethany watched as the mess in Lauren's mouth moved about, before eventually being penetrated by a tongue, and then it was almost all gone. On Lauren's face was a look of disgust but Bethany knew she was loving it.

"Bethany, those turds were nastyyyyy!" She said with a smirk.

"I guess so... I do have a tendency to drink up a toilet!"

"I can see why."

"Now, I think I'll let the rest out on your tits."

Lauren just smiled in reply.

Bethany lowered her shit-covered bum a few inches above Lauren's chest. She grabbed her cheeks with both hands and spread them, which gave Lauren a wonderful view of the now shit stained chilli ring. It twitched, before opening slightly. A soft, green-ish poop, with the consistency of the ones from earlier, snaked down and came to rest on Lauren's right breast. It kept coming and laid itself down across her chest, before curling round and beginning to stack. The smell was as bad as before, and it was amazing. But Bethany did not have as much to go as she had before, and the poop was cut off after going over Lauren's tits and curling round. Bethany looked round to examine the damage, and again saw such a hot sight that she just needed to take a picture. She picked up her phone from the counter that she'd placed it on and snapped a photo. She put it back and went back to Lauren. Bethany was new to scat, but seeing as Lauren had eaten an entire load from Bethany, Bethany at least should try it. Bethany bent down and picked a bit off from Lauren's chest. She lifted it up to her mouth and, still unsure, plopped it into her mouth. The taste was incredibly bitter and the texture was nasty. Bethany could see why Lauren had called them nasty. Lauren let out a giggle as she saw Bethany cringe. Bethany spat it out into the toilet.

"Yeugh. I can see why you said they were nasty."

"Yeah, I don't make them much so I haven't had much experience with that type," Said Lauren, "but mine are better. Trust me, you can see for yourself sometime soon if you want..."

"I think I'll leave this particular shit to you." Said Bethany with a smirk. She scooped up the poop and packed it into Lauren's mouth, almost a repeat of earlier. Lauren did her best to chow down on it, and worked through in a minute or two. Now all that was left were two, shit streaked girls.

"Lauren, clean my asshole!" Said Bethany as she hovered her dirty ass over Lauren's mouth. Lauren went full out, licking and licking to get rid of the mess that was on Bethany. The taste was not important now. Eventually Bethany must have had enough, because she got up and checked in the mirror, Lauren had done a good job, leaving just discoloured skin behind. Lauren also got up, and motioned for Bethany to come into the shower with her. They both showered until they smelt clean and looked normal, before going to bed with each other.

They had both had an experience that would shape their futures.
