By Daddy's Psychotic Demented Princess

Sitting on the toilet, sobbing softly, shaking and straining, she clutched onto his hands tightly. He was kneeling on the floor in front of her, holding her hands, talking soothingly to her.

"But it HURTS, Daddy! I can't do it, it hurts too badly!" she wailed, tears in her eyes.

"I know honey." he soothed. "But you have to, it has to come out."

Sobbing softly, she pushed and strained harder, but the large log of impacted shit wouldn't budge. This was an ongoing problem with her, bad constipation.

After at least 20 minutes of straining and pain, it was evident it wasn't going to move. She dissolved in tears when he finally said that they were going to have to do the thing the doctor suggested. They had gone through this enough that she knew exactly what he was talking about.

Grabbing a soft mat that was rolled up in the corner he unrolled it in the middle of the floor and placed an ultra absorbent bed pad in the middle of it.  Kneeling down by the mat, he grabbed a small basket from under the sink and sat it beside him on the floor, then smiled at her and patted the mat. With a deep sigh of resignation, she stepped out of her pants and undies then trudged over to him, head hung low. Lying on her back, butt centered on the pad, she drew her knees up to her chest and clasped her hands behind them, exposing both her pussy and arse to him.

"Good girl, Chrissy." He said, rubbing her bottom softly. Grabbing a tube of KY from the basket, he squirted a generous amount on two fingers, and then started to ease them into her slightly distended anus, working them around, lubing her up really good. When he was done, he pulled his fingers out and placed them on either side of her anus and let the thumb of his other hand stray upwards and softly rub her clit.

"OK honey," he said softly, looking up into her eyes, "start pushing and Daddy will help."

Straining and gripping onto her legs tighter she started to push.  Watching, he saw her anus distend even more as the huge brown log pressed against it, dilating it open as it tried to push through. He started pressing on either side of her anus to add pressure in hopes of helping to get it to slide out, his fingers moving a bit faster on her clit.

Straining a little harder, she bit her bottom lip. A small bit of urine leaked out, tricking down her pussy then over his fingers. This time she could feel, what she was sure was a massive log, start to move. Shutting her eyes she pushed as hard as she could, letting the feelings his fingers were producing, envelop her. An orgasm was imminent, she was sure of that.  Her clit was throbbing harder under his thumb, so he started working faster on it. He could also felt the massive turd start to emerge, the tip of it pushing its way out of her dilated and straining anus.

In a matter of a couple more minutes she came, screaming. As her whole body tensed and throbbed the huge log of shit squirted all the way out of her like a large brown tail sprouting. Lying on the mat, panting heavily, her whole body limp and throbbing, she tried to catch her breath.

As she lay there, he took a warm, wet washcloth and gently started to wash away any remaining shit and piss, carefully looking for any tears or bleeding. The worst part of the whole matter was over, but there were still a couple of things to do yet. Opening a jar of glycerin suppositories, he pulled one out then inserted it deep into her still-gaping arse. There was still a log jam of shit up there that needed be loosened up come out, and this would trigger that.

While watching him through droopy eyes, her thumb strayed to her mouth and she started to suck on it. It wasn't long before she felt the glycerin bullet start to work and the urge to move her bowels again intensified. Letting her thumb slide out of her mouth, she looked down at him and licked her lips. Even if he was her father, he was still one of the sexiest and most handsome men she had ever seen. Tall, 6'6" in his stocking feet, blonde, thick soft hair the colour of corn silk, and so handsome, eyes the color of a cloudless summer sky, a rugged profile and a bright, white smile. His body was deeply tanned and muscular from the thrice weekly workouts at a local gym. He looked more like an athlete or movie star than the computer tech he was. He was her sexy Daddy. She licked her lips and looked down at him.

"Daddy?" she said softly.

Looking up at her, he smiled, "Yes honey?"

"Can we play, please?" She asked softy. An anticipatory shiver ran through her body and her tight little pussy grew even wetter.

Grinning from ear to ear, eyes twinkling, he looked back at her, "Does my naughty little girl want to play with her Daddy?" He asked her in a gruff voice, his cock going from semi-hard to fully erect and throbbing in a matter of seconds.  An involuntary shudder ran through her as she nodded, biting her bottom lip, eyes twinkling. Quickly, he stood up and started to yank his clothes off, looking at her while he did.

Though they didn't look alike, she was small, barely 5 feet tall and 90 lbs, blue-black hair, deep green eyes and a darkly exotic complexion that showed her mother's Indian ancestry, they were very much alike in other ways. How much he didn't know until she had come to live with him a couple of years ago.

For as long as he could remember he had been obsessed with excretory functions, his and everyone else's. After college when he discovered internet porn, he was able to feed his obsessions. His ex had thought it sick and wanted no part of it. After their divorce when he was alone once again he started perusing it, downloading videos, collecting pictures, keeping records of when he went, how big it was, things like that. It was a time-consuming hobby that was his passion. After the reaction from his wife about it he was afraid to bring it up to anyone else, so he perused it online in chat rooms and message boards, playing with people he didn't know, making movies of himself shitting and sitting with it smeared all over him for long periods of time. He was in heaven!

Then Chrissy came back to live with him, so he had to curtail it, lest she found out. But, one day, while doing their laundry, he found a pair of her panties, soiled. That being his forte, he saw them for what they were. They were no skid mark from not wiping properly. She had shit in them, and then tried to clean them up.

He washed them and didn't say a word, thinking perhaps she had just had an accident. Her problem with constipation had already shown itself, so he thought it was related. But at least once a week, sometimes more, he was finding soiled panties. So, finally he screwed up the courage and brought it up to her.

After a lot of stammering and stuttering, she admitted to doing it on purpose.  She said she liked shitting her panties then sitting in them, feeling her own excrement squishing in her arse and around her pussy. Even to pushing it into her cunt. Admitting that for as long as she could remember she had liked it. It had made her mother furious, leading the woman to dosing her daughter with powerful laxatives and huge, frequent, burning enemas that kept her bowels empty so she couldn't. That had led to the constipation problems.

Chrissy had held onto her bowel movements for so long, so she could indulge her mother's belief that the treatments were working, that she couldn't go. By the time she moved in with him, it was so ingrained that it was normal for her and had progressed to a problem.

He was stunned into silence but quickly assured her that he didn't mind and she could indulge if she wished. Gradually he revealed to her over time that he had similar interests and slowly they started doing things together. Progressing slowly from just watching each other, to helping, to sex just how they both liked it, dirty.

Squatting over her upper chest, his hard cock standing straight out in front of him, he strained and started to shit. He could feel her hands on his arse cheeks, parting them, then her tongue on his anus, and licking around it as the huge turd slid out and curled into a pile just above her naked, tea-cup sized breasts. He could feel the very tip of her tongue graze lightly over his stretched anus as the long, thick, dark brown turd slid easily out of his arsehole, making him shiver and his cock throb.

When he was finished, he stood up and pissed all over her, no easy feat when your cock is as hard as an iron bar. After covering her from hair to ankles in what she called 'Daddy's lemonade', he kneeled back down between her legs.

Already, she had her hands in the pile of steaming shit he had left on her chest and was smearing it all over herself. He put his hands in it and started to rub some on her face and in her hair. Smiling up at him, she grabbed a handful, and then smeared it all over his chest and face. Then, she grabbed another heaping handful and coated his cock in a thick paste of it before saying, "Fuck my bottom with your shit, Daddy. Please."

Moaning, he grabbed his cock and smeared it along the outside of her still-gaping arse, getting shit all over it, before slamming it all the way into her in one long stroke. Shifting around to a comfortable position, he then started fucking her fast and hard, the shit on his legs and groin smearing all over her. Inhaling deeply, the stench filled his nostrils making his cock throb harder. She was moaning and wiggling under him, continuing to smear the thick paste of shit on his chest, looking up into his eyes while she did.

Reaching down, he grabbed the huge, hard log she had expelled earlier and started to rub it around her dripping snatch before sliding it deep inside her cunt. Twirling it around, he slid it in and out, fucking her with it.

Grabbing a small piece of shit off her chest she put it in her mouth, tasting its rancid flavor, then, grabbing a handful of his hair, she drew him down and kissed him passionately, passing the turd into his mouth with her tongue.

After swallowing it, he got back upright and looked down at her. His cock was throbbing madly and release wasn't far off, whether he wanted to hold on or not.

"Do you have to poo, honey?" he asked, looking down at her. Nodding, she looked up at him, eyes alight, shaking.

"Poo on Daddy's cock, honey" he said to her, softly.

"Yes, Daddy" she moaned. Then she started to try and move her bowels again. The force of her pushing almost expelled his cock but he held it in place, waiting. As he held the shit in her cunt, his thumb once again went to work on

her clit and started to diddle it fast. In a few minutes, the shit softened by the glycerin started to squash out of her arsehole around his cock like brown, soft scoop ice cream, squirting on his groin and her arse cheeks. That was all she needed to do for him, with a strangled cry he shot his cum deep into her arse with such force he was sure it would come out of her mouth.

By the time his balls emptied, her orgasm had her shaking and writhing all over underneath him. After relaxing and catching their breath they retired to the shower to clean up before heading to his room for the night, exhausted but satisfied. Father and daughter, so much alike, were two nasty, dirty sluts.
