Editor's note: this story contains scenes of incest or incest content.

*****

Believe it or not this is actually based on a true story. The majority of this story is 100% true, some elements were slightly embellished, some were part of a vivid dream, and some parts (names for example) were completely fabricated. Although I have written for many years and hope to become a published author in the future (not necessarily in erotica), this is my first submission. I hope you enjoy as much as I enjoyed writing and experiencing much of the following. This story does contain copious scat and pee fetish material so if this offends you please exit the ride now. Only female scat and there is no scat eating or smearing. All characters are over 18.

*****

I had been with my fiancée, Mia, for 6 years before proposing. I never saw myself actually settling down and having kids with someone partially because I never thought somebody would ever accept me. ALL of me. Sure I am perfectly rational and "normal" in public. In fact I would guess that most people who know me, if they ever had such thoughts, would assume I am very... shall we say "traditional" in bed. If you met my fiancée in public I would assume you would think the same about her as well because I certainly did.

I've always had a thing for Asian girls since I was young. Something I just find fascinating about them. Exotic features, tight cute petite bodies. My fiancée, I assume you have guessed by now, is Asian 5'0" and 110 pounds. Her B cup tits look slightly small on her perhaps, but she has a surprisingly big, nice, plump round ass for an Asian girl her size. She is definitely cute and cleans up very nicely when she dresses up and straightens her long, lushious, wavy dark brown hair. She is absolutely stunning. She could however come across as a bit of a nerd to some at times especially when she wears her glasses instead of contacts.

Mia's younger sister, Tia, is 4'11" and 99 pounds and looks just like Mia only with a slightly more petite body and face with slightly bigger tits and has a more ditsy higher pitched voice. Mia and Tia are often mistaken for twins, just as I thought they were when I first saw a picture of them together. They were both cheerleaders back in highschool but Tia was a flyer for 3 years and is more of the stereotypical cheerleader type personality. Mia is definitely the more intelligent and thus much more interesting to talk to than Tia, so I am 100% happy with my choice, but it's no secret that I would find Tia physically attractive as well.

A few years before this story took place in reality, I even admitted as much to Mia while we were contemplating breaking up. I confessed that I sometimes fantasized about Tia and early on in our relationship I had even stolen one of Tia's pink g-strings out of her dirty clothes which sometimes I would sniff while masturbating. To my surprise, Mia was not horrified at my confession and did not break up with me. In fact (still to this day), sometimes Mia will wear Tia's pink xs g-string when we fuck and we sometimes even incorporate fantasizing about Tia as dirty talk during some of our best sessions. One time Tia came over to our house and went in our hot tub, and when she left the next day she forgot her bathing suit. That night, Mia wore Tia's bikini for me while we had incredible sex.

But that is all just some backstory (and perhaps a story for another time). I promise it will get much more specific, wild, crazy, dirty, and freaky soon.

But first, just a little more backstory. Tia actually got engaged to her boyfriend, Dom, before Mia and I did, and one could argue that they were even more stable financially than us at that time. Not long after their engagement, Tia lost her job and they ended up losing their apartment before they both moved back in with her parents. Now, with that out of the way, this is where the real story begins...

Tia came over to our house one day to relax. She claimed it was too loud and stressful over at the parent's house. I was doing yard work outside and Mia and Tia went to the king sized bed in the master bedroom to chat. They were talking for awhile (Mia informed me later on the details I was not present for) and eventually Tia mentions that she really wants a fat cock head. She tells Mia that Dom's penis is only 5 inches long and skinny.

Mia tells Tia, "Matthew has a nice size. He has a 7 inch cock with a big head. It's long and thick."

Tia says, "Omg, you have everything sissy, I'm so jealous. I want that too!"

"Do you want to see a picture of Matthew's penis?"

Tia just nods in anticipation as Mia starts scrolling through text messages on her phone. Mia ends up settling on a sext I had sent her about a month ago where I'm wearing blue boxer briefs with my cock and balls out with a partial side view and my skin pulled slightly down to show off the big mushroom head.

"Damn it's big, and a nice fat head!" Tia exclaims.

Mia tells Tia, "Matthew fucks balıkesir escort (https://balikesirmetroturizm.com) me so good with his big fat cock he makes me squirt so much all over the bed we put on extra waterproof sheets..." Tia had pulled her leggings down and started masturbating through her thong.

Mia tells Tia, "When you left your bathing suit here I put it on and Matthew fucked me in it. I sprayed so many times... your bikini was soaked in my cum."

"Omg you guys are so nasty." Tia moans softly as she rubs her tastefully trimmed hairy pussy.

"Then I pissed in your bikini too... Matthew loves it when I piss a long thick stream all over him during sex. So much piss... I even stand over him and piss in his mouth and he loves to drink it too."

"Oh fuck, that's so hot!" Tia slipped her panties to her knees with her left hand as her right rubbed faster and harder for a few seconds until she squirted a quick burst of cum on our bed. "Oh shit..." Tia asks, "Does Matthew piss on you too?"

"Yeah, he'll give me a nice oil massage and during he arches a long high stream all over my body and massages me with his piss. He's drank a lot of water and held it until he pissed for over a minute and filled a whole big wine bottle overflowing... if you eat Sugar Smacks the piss tastes sweet too..."

"You also drink his piss?"

Mia says, "A few times."

Just then Tia shamelessly ripped a loud fart and sighed in relief.

"Matthew loves when I fart too. Sometimes I fart loud for him right in his face..."

"Oh yeah?" Tia says, "One time at my old apartment I was outside on the balcony and I farted so loud the neighbor came out to see what it was, hehe."

"Yeah. Matthew would love it if you farted in front of him. Remember that one time I came over to your apartment and you had left a long fat turd in the toilet and didn't flush?"

Tia says, "Yeah, sometimes I don't flush when I leave a big poopie. Like when we were teenagers we would leave big turds in the toilet and not flush, hehe."

"I leave my big turds for Matthew. He thinks it's sexy when I take a big shit..." Mia continued to scroll through pictures and found the (I honestly shit you not) 20 inch long, thick, solid, knobby textured poop log she unloaded for me and laid in the shower (I even got the whole thing on video too... yes, I am an extremely lucky man).

"Look at my big poop." Mia said as she handed the phone over.

"Omg, dang sissy, that's a really long fat one." Tia says in amazement.

"Matthew fucked me in the shower while we stood over it and he shot his load all over my turd."

"Dang, that's so fuckin' hot..." Tia farted and sighed again and says, "I think I have to take a big shit right now."

Mia tells Tia, "Just go right there on the bed..."

I felt the need to take a piss while working outside and luckily thought better than just whipping it out and taking a leak in the yard and came into the house. Surprised nobody was in the front room I call out, "Lovie?" but no response, so I made my way to the master bathroom.

Tia heard me come into the house and slips her leggings and thong off completely to spread her legs and with a devilish grin starts pissing a thick arching stream on the bed just as I walk in.

Tia doesn't stop pissing and I just say, "Oh, I just have to pee... don't mind me."

Tia looks into my eyes and continues pissing a nice thick stream 3 feet into the air and cascading onto my bed for another 15 seconds.

Tia says, "I have to fart Matthew... do you want to smell my fart?"

I honestly can't believe what is happening right now. I look at Mia and she nods approvingly, so I shrug and take off my shirt before hopping onto the pissy wet bed on my stomach and position my head between Tia's sexy toned thighs.

She hesitates for a moment before tensing up and ripping a deep loud fart vibrating the bed and she sighs in relief. Immediately I can smell Tia's hot gas hit my nose. It smells indescribably intoxicating, different yet similar to Mia's farts, unexplainably good and incredibly sexy.

"Oh, fuck, that was a big fart." Tia says.

I then hear a little more gas escape followed by the unmistakable crackling of a turd emerging. Tia grunts, "I'm pooping... I have to poop so bad... I think it's going to be huge."

I just continue to stare in astonishment at Tia's tight little butt hole as it begins to open and reveals the brown tip of a thick turd.

"Tia says, "You like my loud fart Matthew? Whip out your cock and stroke it to my long fat turd."

I sit up onto my knees and pull my shorts down slowly so my cock got hung up in the waistband and continued pulling down. Once revealed, my dick sprung out engorged to its full length and extended swollen cock head and flopped up audibly smacking my stomach before powerfully swinging side to side and swaying back and forth before finally standing up stiff and straight at an intimidating upward angle.

I look down to see balikesirmetroturizm.com (https://balikesirmetroturizm.com) that Tia had already unloaded about 8 inches of her marvelously textured knobby thick poop log and she was still pushing more out.

"Fuck Matthew... look at that huge cock... mmmm." Moaned Tia.

Tia's pussy was soaking wet and glistening from masturbating while taliking to Mia. I slipped my shorts off completely and straddled Tia's 10 inch turd and rubbed my fat cock head on her lubed mound entrance. Tia grabbed the inside of her legs and pulled her butt up as the final 4 inches of poop slid out and pinched off and she started spraying even more piss again all over my chest, but only for a few seconds. She grinned at me which morphed into biting her lip as I slid the full length of my cock into her tight wet pussy. The smell of Tia's thick 14 inch long cute asian girl poop she laid on my bed was so incredibly arousing as I sensed she was already ready for me to go straight into pounding her hard. I wrapped my arms around her toned legs and waist grabbing her softer buttocks from below to support her and spread her legs and immediately began wrecking balling her, pounding hard and fast and deep thrusts which were immediately met with the sloshy tight grip of Tia's cookie...

"OH MY GOD MATTHEW!" Tia screamed. "I'm going to fucking cum already, YOU'RE GONNA MAKE ME FUCKIN' CUM!"

My cock was fully engorged rock hard, and at its extra extended max thickness and teeny Tia took my whole girthy length all the way to the balls like a champ. Tia straightened her legs and spread them out wider as my swinging ball sack audibly slapped her taut little round ass cheeks on each deep thrust.

"Oh Matthew... give me that fat cock head... fuck your cock is so long and thick... so long and thick..."

I could feel Tia's pussy begin to swell with a growing pressure as I continued to savagely thrust past the increasing force.

"Oh my God Matthew, your cock is so much bigger than Dom's... you're gonna make me cum... I'm gonna cum so fuckin' hard to your fat cock head Matthew!"

Tia's pussy began to slosh loudly with each rapid thrust and I was able to force my rock hard erection a dozen or so more times until finally the force of Tia's orgasm was too powerful it shot my boner out, and like a dam bursting Tia let forth a power washer squirt all over my cock and chest and 5 feet up into the air accompanied by her squeals of intense pleasure.

I sat up onto my knees still straddling Tia's monster poop log and looked over to see Mia watching us and masturbating on her stomach when Tia moaned, "I want to drink your piss Matthew... shoot your hot piss into my fuckin' mouth..."

Tia sat up and scooted her butt so her back was against the headboard. I shuffled my knees closer to straddle Tia's thighs and held my penis at the base of the shaft with my thumb on top to help aim.

"Piss in Mia's mouth too..."

Mia got into position on her hands and knees next to her sister. They both opened their mouths and stuck out their tongues in anticipation. Despite my raging boner, I miraculously began to feel the urge to pee again and I told them, "I can't believe I think I'm actually going to piss... I did drink a lot of water and I ate Sugar Smacks this morning..."

I could feel the piss getting close and I gave Mia a 3 second burst into her open mouth first. She closed and swallowed then licked her lips and said, "mmm, it tastes good babe, let Tia try some."

I grabbed my penis and angled it back toward Tia and filled her mouth overflowing with a 5 second burst of clear piss. She swallowed the entire mouthful in one gulp like a shot of tequila and said, "Oh my God, your piss tastes so fucking good Matthew. It's better than beer."

"Do you want more Tia?"

"Hell yeah!"

I aimed my cock again and gave Tia another 4 second power burst of piss into her mouth and she gulped it down.

Tia moaned, "Don't stop Matthew just keep pissing..."

I sighed in relief as it felt so good to just let my piss stream flow without stopping it this time.

Tia gulped down all she could like she was at a drinking fountain parched from one of her workouts, and when she got behind I quickly angled my stream to Mia to fill her throat before returning back to greedy Tia's eagerly waiting mouth. I estimate Tia drank around 2 cups of piss and I peed for a total of at least 50 seconds, but eventually the stream began to run out. I shot a couple more small spurts of piss and shook off the last drips from the tip and Tia swallowed every last drop. Tia leaned forward grabbing my shaft and licked and sucked my penis off like a frosting covered spoon.

"That was a lot of piss... so much piss... it tasted so fucking good Matthew..."

I still had not cum yet and my cock was insanely long, thick and hard and Tia noticed.

"Get on Matthew sissy, I want to watch you two fuck."

I laid on my back in the middle of the bed. Tia's massive poop was off to my left about a foot away from my shoulder still undisturbed from where she had laid it. Tia grabbed my cock and stroked it while motioning for Mia to come sit on it.

Mia hovered over me and squatted down as her younger sister angled my cock. Tia had a close up view as Mia's tight pussy lips spread open to accept my fat cock head. Mia moaned as she took the entire shaft all the way to the balls like a good girl and began riding me slowly at first. Tia continued to stroke my shaft and cup my balls as Mia began picking up the pace. I began to suck on Mia's tits that hung down in my face as Tia moved to our side and said, "Oh yeah, fuck Matthew while he sucks those boobies."

Tia still had her shirt on at this point clearly with no bra (as she almost always is braless certainly around me at least) as the shape of her breasts and hard nipples were outlined by the cotton material soaked in my piss. Tia sat on her knees and whipped her wet shirt off over her head, allowing her large firm boobs to fall out and spring forth bouncing and jiggling slightly as she sensually swung her hair about. Tia sat there on her knees completely naked and paused for a moment to look at her big poopie while Mia and I continued to fuck.

Tia flashed a devilish grin and moved carefully using both of her small hands to pick up each end of her solid 14 inch long knobby turd to hold it together and slowly transferred it onto my chest. Tia's long, thick, solid log of sexy asian girl shit extended from my pecs to just past my belly button.

"Damn, that's a huge shit Tia!" Mia moans. "I'm gonna cum! Fuck, I'm gonna squirt all over your fat turd Tia..."

Mia's pussy began sloshing and a torrent of pussy juice violently forced my cock out causing it to smack audibly against Tia's turd as Mia sprayed cum all over Tia's shit and my body. Mia shuffled forward and squatted her pussy down on my face and began rubbing herself on my welcoming tongue and mouth.

"Piss in Matthew's mouth!" Tia ordered. "I want to watch Matthew drink your piss..."

Mia obeyed and stood up straddling me, straightening her legs, and bending over slightly. Tia stood over my hips and squatted down impaling herself slowly onto my stiff cock to get into position to watch. Tia began riding me slowly as Mia unleashed a thick clear yellow piss stream first right onto Tia's poop and then began swinging her hips to angle it into my mouth. I could see Tia's tits bouncing between Mia's spread legs and piss stream as she fucked herself on me harder and harder while watching Mia spray a huge load of piss all over my body and her own turd. Mia settled on my mouth and I took in two big gulps of her sweet musky nectar.

"Baby... I have to poop too..." Mia whispered as she got back down onto her knees with her ass up and began making out with me. Tia's face was about 2 feet from her big sister's round naked butt as she ground her pelvis even harder into me now. Mia's ass hole began to open as Tia watched and finally realized what was happening.

"OMG Sissy! Yes, shit on Matthew... shit on Matthew... fuck yes! Shit on my shit sissy! Shit on my shit... Oh my God I'm gonna cum! Holy shit Mia, your turd is so thick!"

Tia watched as Mia squeezed out a long fat turd. The tip hit my stomach and Mia's turd began to curve over the top of Tia's poop as more continued to inch out.

Tia couldn't take it anymore and began thrusting her hips wildly as she smacked her pussy spraying cum so hard she shot it clear over us and against the wall as she squealed in intense pleasure. Tia's squirt sprayed powerfully against the wall over my head and cascaded down all over our naked bodies just as Mia pinched her hefty loaf. My cute, tiny asian fiancée's massive 12 inch long turd smacked loudly into my chest finally coming to rest draped across her teeny little sister's 14 inch long slightly thinner turd.

Mia hopped off to the side after dumping her log on me as Tia stood up and turned around to show me her tight little sexy round buns. "Does Matthew need to cum? Do you want to shoot your huge load all over this hot ass?" Tia teases as she caresses her own butt cheeks. Tia squats her ass down hovering just over the huge turd pile on my chest and holds it there for a few seconds before straightening her legs and bending over slightly. Tia shook her thighs causing her ass cheeks to jiggle perfectly. She was twerking for me!

Mia laid on her stomach so I could see her ass in the air and grabbed my shaft and started stroking. Tia lowered herself, touching the tip of my cock head to her butt and rubbed herself on me.

"Or, do you want to shoot your huge load in my ass? Fuck my tight little ass hole with your fat cock? Stretch me open and fill me with your thick white cream?"

Tia lowered herself more as Mia helped angle my cock. My penis started to bend as it met the resistance of Tia's ass hole, but finally my cock won the struggle and the fat head suddenly disappeared as it popped into Tia's butt. Tia moaned at the feeling of me intimately inside her, filling her, stretching her open.

"Oh Matthew, that feels so good... your fat cock inside my ass makes me feel like I need to take another dump."
