Character introduction:
Mark is a 17 years old, about 5'11" with a toned body, but not bulky, weighing in around 170lbs, most of the girls at school considered him to be the stud of his grade.
Angie is Marks younger sister, she is 15, 5'6, about 105lbs, a B cup, and a tiny frame, her dark brown hair falls past her shoulders, her breasts are full and perky.
And so it began...
"Ang, get in the car" Mark says as he pulls the car up to the curb.
"Mark, thank you for picking me up, I really don't feel well"
"How drunk are you?"
"fuck off Mark, I'm not drunk I'm just not feeling well. You're not gonna tell Mom and Dad about this are you?"
"what about my 15 year old sister being at a party at midnight where everyone is drinking.... We'll see, for now, let's just get you home. You're so lucky they are out for the weekend!"
"OK well let me know what I can do to make you keep this to yourself?"
"I'll think about it, laundry for a month sounds like a start"
"ugh, you can be a real jerk sometimes!"
"Hey, I didn't have to come get you OK"
"You're right, thank you Mark, can we head home, I'm really not feeling so great"
It was dark out as Mark drove along the freeway to their house, Ang had her feet up on the seat holding her legs to her body.
"Mark, I don't think I'm going to make it home, you're gonna have to find me a bathroom"
"Shit Ang, we're like 5 exits from home and there really isn't anywhere to go at this time of night, we should just get you home and you can throw up there"
"I don't have to puke, I... um, feel like I"m gonna ya know... do number two" Ang said choking back tears
"Just try to hold it in Sis, I'll get you home as quick as I can ok?"
"Ok, but hurry, I don't know how long I can keep in it"
As she finished her sentence her stomach rumbled, she felt her anus pucker as a fart escaped from her ass echoing off the leather seats of their parents Mercedes. The smell filled the car but Mark didn't say anything, he knew his sister would be embarrassed. As they drove in the night the feeling of needing to go was getting stronger. Angie sat uncomfortably in the seat, a few moments later fart pushed its way out of her tightly squeezed hole, again it rumbled off of the seat and the smell grew stronger in the car.
"we're almost home Ang, just a few more minutes and we'll get you to the bathroom"
"Mark I don't think I have a few more minutes, it really hurts" and she began to sob softly.
Mark reached over and rubbed his young sisters back.
"uggggggh" Ang moaned as her stomach turned and his time she couldn't keep it in. She felt her asshole expand as her shit pushed its way out and began to fill her panties. The soft shit continued to squish out, her jeans stretched as the load grew, Angie was sobbing loudly now. Her shit oozed between her ass checks and pushed forward towards her bald young twat, as it filled her panties it pushed backwards and up towards the edge of her jeans. The smell in the car was unmistakable and was becoming overpowering; Marked looked over at his crying sister `fuck, I should have pulled over for her, my poor sister' he thought to himself.
"I'm so sorry Mark, please don't hate me" Angie said between sobs
"No no, I'm the one that's sorry Ang, I should have pulled over; I thought you would make it"
As Ang sat there her intestines continued to rumble, by this time she had lost the ability to control her anus and more shit flowed out and into her soiled panties. Her jeans were now stained brown and the shit oozed all the way down between her thighs. Her crying had subsided as she sat in silent shock, complete disbelief at what had just happened.
"We're only a minute away hun, we'll get you inside and get you cleaned up, just another minute ok sis?"
She nodded at her brother not saying a word, her ass was wet and warm and the smell was pungent in the car. As they pulled into the garage Mark hopped out of the car first and ran around to open his sister's door.
"Here, let me help you" and he reached out his hand to help his sister out of the car "don't worry about the car seats, they are leather they'll clean up easy enough. Let's get you into the shower"
He took his sister by the hand and guided her into the house. As she walked she could feel her shit move down her legs, her jeans had dark brown stains running down her inseam.
"I can take it from here Mark, I'm so sorry about this"
"Nonsense Ang, these things happen, let me help you get cleaned up, it's the least I could do for not stopping for you"
"Mark, I'm your sister and I'm getting too old for you to see me naked"
"Oh come on, I've seen you change up at the lake plenty of times, and you walk around in just your night shirts all the time, it doesn't leave much to the imagination. I've seen my girlfriend naked a bunch of times now it's not like the female body is new to me."
"Ok, I guess you're right, this is just so embarrassing"
"Don't be embarrassed, it could have happened to anyone, let's get you out of those messy jeans and into the bath"
Mark turned on the water to the bathtub and got the water nice and warm, he sunk the plug in the drain and let the tub fill with water.
"Here put your arms up"
Angie did as he asked and raised her arms about her head, Mark slipped her shirt off, he reached around behind her and as he did she put her arms around him and hugged him.
"Thank you for always being here for me Mark, you know I love you right?"
"I know Ang, I love you too" he unhooked her bra and let it fall to the floor exposing her beautiful perky breasts, the bathroom was cool and as a result her nipples were firm. He reached down and undid her jeans, he slowly slid her pants down to her ankles, careful not to spread the mess. Mark put the jeans off to the side of the room, he smelled the shit strongly now and he heard his sister start to sob again. He leaned in and kissed her forehead.
"Hey, listen, it's ok Ang, we'll get you cleaned up and good as new, no one ever has to know about this ok?"
She nodded and he wiped the tear from her cheek and gave her a reassuring smile. He reached back down and slowly slipped off her shit filled knickers.
"I think I'll just throw these out if you don't mind?"
"yea they can go" she said blushing at him.
He pulled the garbage out from under the sink and put it in the corner; he dropped the soiled panties in the trash and looked back at his sister. `Wow, she has really grown up in the last couple of years' he thought to himself. He went over to the tub and dipped his hand in to check the temperature, it was nice and warm so he shut off the tap.
"OK Ang, why don't you get in and we'll wash you off"
She gave him a small smile, `he's being so sweet to me' she thought to herself as she climbed into the tub, she stood there and looked back down at her brother who reached over and grabbed a sponge off the edge of the tub and dipped it in the water. He sat up on the edge of the tub now and raised the sponge to the top of his sisters wonderful firm ass, he tried using the sponge but it just smeared the shit around on her ass.
"Sis, I'm gonna have to use my hands to get most of this off, then I can rinsed it off with the shower head ok?"
"Are you sure you aren't too grossed out, I can take care of it if this is too much for you?"
Mark didn't respond but rather he reached up and scooped some of the shit from between his sisters thighs and dropped it into the tub. He reached up again this time sliding his hand from the top of his sisters bum down to her thigh. His hands were firm but gentle and Ang accidentally let out a moan. Mark pretended not to notice as he repeated the process on her other cheek. On his third pass he cupped his hands between his sister's pussy and her pink little rosebud, he quickly scooped his hand upwards filling his hands with his sisters shit. "uuuhhhhhh" Ang cried out this time as her brothers hands passed over her asshole. Mark now became aware that he had become fully erect touching his sisters intimate areas. He shifted awkwardly as his bulge pressed uncomfortably into his jeans.
"Are you ok bro?" Ang said watching her brother sit on the edge of the tub.
`Ya, ya I'm fine, I'm just um, uncomfortable is all, it's getting really warm in here"
"Well if you're warm you can always take off your shirt and pants.. I mean if you wanted to"
Mark wasn't sure what to do, he was really uncomfortable but surely his sister would notice his throbbing erection if he took off his pants. He thought maybe if he turned around to take them off and then sat down before spinning around on the edge of the tub she wouldn't notice.
"Ya I think I'll do that if you don't mind?"
"No go ahead, I'd probably feel less embarrassed since I'm standing here naked in front of you still half covered in my own poo" she said as she blushed
With that Mark stripped off his shirt and tossed it into the corner of the room, he stood up with his back facing his sister and dropped his jeans to the ground kicking them to the side, he sat back down and turned to face his sister.
"uh uh, that's not fair, if I have to be naked, then you have to be naked"
"I um, I can't do that Ang, it's kinda embarrassing"
"Really Mark??? What can be more embarrassing than being covered in your own shit in front of your brother?"
"I um, I kinda, ugh, your my sister, I shouldn't be having this problem!"
"What problem?"
"Nothing, I don't want to say"
"Say what Mark, come on don't get shy on me now" Feeling awkward all of a sudden Ang sat down in the tub. As she sat down she could clearly see `his problem'.
"OH!" she blurted out. Mark immediately started to blush. "Oh come on bro, that isn't a problem, I mean I am a good looking girl, I might be offended if I didn't get that reaction!"
"But Ang you are my sister, you shouldn't have that affect on me!"
"Well I'd be lying if I said I was sorry, but it's kinda nice to know I'm attractive. Anyways I'm getting embarrassed so take off your jockies and finish cleaning me up or I want you to leave the bathroom and I'll take care of myself"
Mark paused before standing up
"really, so you're just gonna leave me here alone?"
"no, I wouldn't do that to you Ang" Mark replied as he pulled his jockies down and dropped them to the floor, exposing his erect cock. "Mind if I join you in the tub?"
"There's lot of room, but are you sure you want to get in, I mean the water is pretty dirty from my poop?"
"I don't mind sis, it'll clean off but let's get you cleaned up first shall we?"
Mark slid himself into the tub sitting with his legs crossed facing his sister. Ang smiled at her brother and stood up, her shitty pussy now at his eye level.
"Thank you for being so kind to me Mark, you didn't have to do any of this for me"
"It's ok; I would do anything for you"
Mark grabbed the sponge from the edge of the tub again and dipped it back in the water
"You're going to try that again? It didn't do much good the first time...."
"Well I have to clean off your... um... private bits, so I thought I would use this, I don't want to make you uncomfortable..."
"well that sponge doesn't do any good so just do what you gotta do to clean me up, I'm ok, I promise"
With that Mark reached up and cupped his sister's twat and slid his fingers up towards her belly button once again filling his hand with her poo. He dropped the shit into the tub and rinsed his hand. He reached back up and cupped her twat one more time to ensure he cleaned that area well, as he moved his hand up this time two of his fingers slightly entered into his sisters pussy folds.
"UHHHH" Angie moaned before she should stop herself.
"Shit, are you ok sis? I'm sorry!"
"don't be, that felt really good"
Mark wasn't sure how to respond so he stood up in the tub
"Ok sis, I think we got you all cleaned up, why don't I rinse you off with the shower"
"Ok, that works" Ang replied with a disappointed tone. Mark paused for a moment taken back at what he thought his sister was implying. Mark pulled the shower curtain closed, he bent down and pulled the plug out of the tub, his face was just inches from his sister's twat that he couldn't help but stare at.
"Mark, are you gonna turn on the water or what?" she said startling him.
"uh ya here let me" as he reached around his sister and turned on the warm water. He removed the shower head and brought aimed it at his sister. First he rinsed off her breasts and then the bald pussy, without being asked she turned around and he rinsed off her firm ass. He reached down and pulled her ass cheeks apart exposing her pink rosebud.
"There I think you're as good as new sis"
"Thank you for being so sweet Mark"
"It's ok; you know I'd do anything for you"
Mark turned off the shower and hopped out of the tub, his sister followed behind and they dried themselves off in the steamy bathroom. Mark left first and returned to his room to put on some boxers, Ang returned to her room and slipped a night shirt on and hoped into bed.
"Mark" she called out
Mark came to her door, standing in just his boxers "ya Ang, what do you need?"
"Can you lay with me Mark? at least until I fall asleep? I still don't feel great and want you to comfort me"
"ya, sure, let me just turn off the lights and check the doors and I'll come back in a minute"
By the time Mark returned his sister was asleep in the bed, `well maybe I'll slip into bed with her just in case she wakes up in the night' he thought to himself. He walked around to the other side of the bed and pulled back the covers. He got into her bed softly not wanting to wake her up. As he reached up and turned off the light on the night stand he put his arm around her and closed his eyes. What he couldn't see was the small smile his sister gave as he put his arm around her.
