For some time now, Ruth had a fantasy of getting stroked by a big dog but she had no real desire to actually do it and as her fantasies went, it was great in her brain. She never gave any serious thought to doing it, so when it happened it was a great surprise to her.

A month previously, her husband had bought a two year old Boxer and had gone out of town on business, so she was at home alone with the dog. Damon was a very large dog. He weighed a huge one hundred ten pounds. He had a large brown head and a smooth glossy golden brown coat. He was a friendly dog, was house broken and accepted commands well and so in a short time he had become a part of the household as if he had been with them for years.

The Friday evening after her husband had left and she had dinner, fed Damon and had taken him for a walk. Ruth sat in the basement watching the television and Damon lay at her feet curled up as if half asleep.

The movie that was showing had a lot of sex in it and as Ruth watched she found herself becoming excited, in fact she became very horny and wondered in her mind, why it was that whenever she was horny like that, her husband was never at home. As she became more turned on watching the movie, she slid her right hand under her skirt, pulled the crotch of her panties aside and began playing with her pussy.

Soon the room was filled with the smell of her pussy as she lay back in the sofa, legs spread apart, pussy lips pulled open, fingering her clit, and her juices oozing from her pussy. As she lay with her eyes closed, masturbating, she slipped into another world. Her reverie was disturbed by a sensation that she had not produced. When she opened her eyes to see what caused it, she saw Damon’s body in front of her. His great head was under her skirt and she realized that he was creating the sensation with his big, rough tongue licking her crotch.

Her first reaction was to push him away, and she did, but he returned, burrowing his head a little deeper between her legs and continued his licking. He seemed to know just where to lick because he concentrated on the area around her clit and Ruth just eased her body lower down into the sofa. This made her ass hang off the edge of the cushion. She pulled the panty crotch aside to expose her pussy fully and let him go to work.

In a minute Damon’s tongue had her on the verge of erupting into an orgasm but she closed her legs and pushed him away because she didn’t want to come too soon, she wanted to prolong her enjoyment of this situation.

Damon barked at her and when she opened her eyes to look at him, he was standing looking at her wagging his tail with the biggest hard-on that she had ever seen on a dog. His sheath had retracted and his big, red dick was jutting out under his belly. It was at least eight inches long, bright red and as thick as the space formed by putting her thumb and forefinger together to form a circle! “Oh, poor Damon,” she said “you want some relief too ... Come let me help you.”

She reached under his belly, took his big cock in her hand and began stroking it. Within a short time, Damon began humping against her hand and he kept trying to bury his nose back up into her crotch. She wondered if Damon would know what to do with his big cock as he had with his tongue if she put it near her wet pussy. She stopped stroking Damon’s cock, pulled her panties off pulled her skirt up around her waist, exposing her bare ass and knelt on the carpet with her elbows resting on the sofa. Damon immediately burrowed his nose into the crack of her ass and its coldness made Ruth jump. He licked all in between her ass cheeks until he found her wet pussy and then he concentrated his efforts there. She raised her ass and lowered her chest onto the sofa, spread her legs wide apart and jutted her buttocks back to open herself up better to Damon’s invading tongue. Damon went to work. She enjoyed his licking and couldn’t help thinking, “ I certainly could enjoy a big cock now.”

As if reading her mind, Damon stopped licking her ass and pussy and jumped onto her back. She was surprised and tried to push him off but he was too heavy for her and he had no intention of moving. He started stroking, jabbing his dick wildly into the air. His cock struck her backside, then the back of her legs and kept hitting until it finally found the space between her legs. He continued humping and Ruth was not sure whether she had subconsciously shifted her backside to find the stabbing cock or not but all of a sudden the cock found its mark and lodged between the lips in the opening of her pussy. Instinctively Damon seemed to know that he was in the right place and drove his cock deep into her.

She yelped in pain as the large dick cleaved her pussy open and sank into her.

Damon immediately started stroking hard and fast and the friction was very painful. She struggled to escape to no avail and so she opened her legs as wide as she could to accommodate his big tool in an effort to ease the pain, as she lay pinned under his great weight.

Gradually the aching subsided, as the leaking juices from his cock mixed with her pussy juices. The dog seemed to know his work. His front paws seized her on either side of her waist so she could not pull away from him and he drove his cock deeper and deeper into her, distending her pussy and forcing her to take all of his huge dick. Her pussy was distended beyond her muscular capability.

Damon kept driving his cock into her until he hit a spot deep inside that produced visceral pleasure within her bowels and Ruth closed her eyes as this new pleasure took control of her mind. When she could think again, she realized that she was humping her body in time to Damon’s thrusts. Her pussy felt like a low-grade fire was burning inside of it, and it slowly spread up her belly and into her breasts. Her big nipples were as hard as she could ever remember them being and they throbbed and burned in time to Damon’s fucking rhythm. Before she could prepare for it, her body spasmed and her orgasm erupted from deep inside her pussy. Ruth’s hands dug into the sofa as the pleasure wracked her body. She squealed with sweet pleasure.

Somewhere within her cum hazed mind warning bells went off signaling to her that if she didn’t move away from Damon he would embed his knot in her. Somehow she found the energy to shift her ass and prevented Damon’s cock from penetrating any deeper. Damon kept humping for a while. Her pussy was now able to take his full size and she was so wet from his leaking and her juices, that there was no longer any pain. She kept maneuvering her ass to prevent his knot from entering her.
