Claire's cunt gushed as the doggy-dick began to swell even more inside of her. She loved the feeling of a dog cock expanding inside of her, starting out long and thin and quickly swelling to thick and hard. She would soon be feeling his knot, small at first, then growing until she could feel her pussy stretching with each jab. She knew she should stop him from tying with her. She should reach down and grip his cock above the knot to keep him from sliding the every growing lump of hard flesh inside of her. Filling her until they were locked together. She reached down between her legs. Someone might come along the path any minute now. How humiliating to be caught tied up with a dog out in public. Her pussy twitched.
She should really stop this. She should stop his growing knot from swelling inside of her. Before it was too late. No matter how good it felt when the fat knot spread her pussy lips and grew inside of her baby canal. She really must stop it from happening. She knew she should. "Just a moment more," she promised herself, and she would grab his cock, just in front of his fabulous, tasty, thrusting, hard knot, and keep it from entering her before it was too late.
Claire looked up and down the path. She felt Earl's hot breath on her neck. Her pussy felt so good! Oh god! She wanted it. She wanted it so bad! She wanted the fat, swollen knot filling her up. Filling her tight pussy so much it almost hurt. Damn the consequences! She had fully copulated with him, it was, after all, the only way to mate with a dog. It was how nature intended. She could not deny millions of years of evolution and the incessant needs of her pussy crying out to tie with him. To have him make her his bitch. To feel the hot sperm filling her up and not able to escape. To let him know her pregnancy was definitely ensured.
Claire withdrew her hand and braced herself against the wall. She pushed back as Earl fucked her. She felt his knot growing. She closed her eyes and luxuriated in the feeling of her lips spreading wider and wider with each thrust of his long, hot, poker-like cock and the growing lump of hard dog-flesh at its base.
The dog's cock was now an angry purple and deep red color. His piss-hole squirted so much pre-cum, it dripped out of her snatch. His cock was thick. His knot grew thicker. Claire felt its hardness repeatedly entering her, until she knew it was time and clamped down upon it. She held it in place. Her tight pussy captured him completely.
Earl yelped with surprise. His toes scrabbled on the hard concreted as he strove to drive his puppy-maker deeper and deeper into his bitch. His balls began to tingle each time they slapped Claire's ass. He whined with joy as his cock throbbed, his knot expanded, and he knew he was now fully tied with his bitch. He began to shoot into Claire, his body quivering. He pumped his potent sperm into her, pushing Claire against the wall.
She felt his hot cream and imagined it filling up her uterus. She pulled down her blouse and let her soft, pale breast bounce in the cool air. She pinched her nipples until they hurt. She began to shake as her orgasm washed over her body. Her pussy spasmed, squeezing the fat doggy-dick tighter and tighter.
"Oh! Earl! What a cock! Do it, baby! Do it. Fill me up with your hot cum! Get it all out, lover! Fuck me! Fuck me! Ah-eeeee-iiiiii!"
Claire came over and over again. Her pussy was stuffed full of thick dog cock. She was filled to the brim with warm, thick, dog sperm. Earl's huge knot kept all of their sexual fluids locked inside of her. She could feel her bloated pussy expanding as Earl emptied a year's worth of sperm inside of her. There was so much, she felt it slosh inside of her.
She came down from her orgasmic high, feeling Earl hot breath on her as he panted in her ear.
"Mmmm-mmm, Earl," Claire sighed. "I wish you were my dog, we could fuck like this every day. Duke wouldn't mind. He gets enough pussy."
Earl smiled happily. He drooled on Claire's shoulder.
"Did you like that boy? Did you like fucking Claire's tight, little pussy? I bet you feel better now, don't you? Now that your big 'ol doggy-balls are emptied. Huh boy?"
Claire knew she was going to be late for work today. But, it was worth it. She breathed out a long sigh of contentment and began to hum a happy little tune as she waited for Earl's knot to shrink.
Before long, Earl began to get restless. His hind legs were tired from standing up for so long. "Just wait a minute, Earl," Claire said, noticing his agitation. "You just keep resting on me a little while longer."
But, Earl didn't want to wait. With a lurch, he hopped off of Claire's back.
"Earl! Unnghh!" Claire grunted as his huge knot tugged against her tight hole. He almost pulled her to the floor. With a quick hop, he turned around, bending his still-swollen dick backwards until he was tied with Claire butt to butt. He started to walk away, but Claire squeezed him with her pussy, hard. "You stay, Earl! Stay right there!"
Claire felt his hard knot tugging against her hole. They weren't getting untied anytime soon. 'Oh, why do I let my pussy do all the thinking,' Claire asked herself. In less than a second, she answered her own question. 'Because it feels so good!'
Just then, she hears voices coming down the path. Startled, she trembled as she tucked away her breasts. She stared at the sounds.
'Oh god, oh god, oh god!'
The sounds got closer.
'Please keep walking, please keep walking, please keep walking!'
To her horror, Claire saw a family of four walking down the trail. Her trail! They were coming towards her. Would they see the shelter it was occupied, and take the path to the right, or take the path to the left, to the wide open rear of the shelter? If so, there would be no hiding.
Claire noticed a little boy taking a step on the trail to her hiding place.
"Oh Shit!"
