Dawn moaned quietly and slipped down, scooted her ass a little ways forward on the grass. She was trying to make it easier for the dog to eat her soft pussy, but she was too tightly bound against the trunk of the tree.
It didn't bother Tonto at all. He snorted and sneezed and sniffed as he slobbered all over the girl's thighs and lower tummy and pussy. He wet her cunt good with his warm saliva. He worked at her cunt hard, now and then nipping her smooth wet flesh with his sharp teeth, bringing a slight startled cry from deep in the girl's throat.
Dawn was horny as hell, and she knew it. She wanted nothing in the world but to come again, to come as hard as any woman had ever come. To have it last forever.
She grunted and tried to pump her pussy against the dog's face. Damn the cords that held her in place. She ached and hurt all over, but the pain was nothing now. She wanted to come. She had to come. She felt the sweat trickling down her tits again. She gasped and gulped more saliva, felt the stone grind against the backs of her teeth. She forced her mouth wider open. Her head rolled against the tree trunk, jerking from side to side as the rising tide of her lust swept over her, blotting out everything else.
The big dog's tongue was driving the little girl mad with pleasure. Her whole body was on fire with need. She was humping the dog's snout with tiny jerks of her ass. Her stretched thighs quivered with the strain of her desire to clamp them tightly around the great animal's powerful neck, hug his lapping nipping mouth to her oozing pussy mound.
Tonto growled deep in his throat as he stroked his tongue along Dawn's warm wet cunt, tasting the sweet juices of her young pussy.
He twisted his head, butted his nose hard against her clit in a wild effort to drive his whole snout between the girl's tender pussy lips and up inside her virginal cunt.
Dawn began whimpering softly, and softly purring. If only she were free of these tight painful cords, she would spread herself open for this wonderful animal, hump his face, let him lick her whole tight cunt with that beautifully rough and wicked tongue of his.
She gulped, feeling the stone against her teeth. She gagged on her own saliva again, and cursed the fucking little prick of a cowboy who'd left her like this, unable to get her cunt into the right position for Tonto's tongue.
The dog pawed at Dawn's bare thighs, scratching the soft flesh with his claws. He wanted her to lean back, let him at her. He wanted her on her belly, her ass lifted high, so he could fuck his huge long red cock into her fucking cunt slit.
Tonto suddenly reared his head up. He growled in anger and frustration. He whipped around, cocked his head at the cords around the girl's ankles. Experimentally, he nipped at the twisted knee sock that held Dawn's leg against the sapling.
Oh, yes Dawn thought. Yes. Chew through it, boy. Untie my legs. Oh, yeah, big doggie. Untie my legs, and I'll let you eat me and drink my come. Yeah, doggie, do it.
Tonto nipped into the sock, pulled back hard, his head low and his ass raised. He growled, dug his paws into the ground, and yanked harder, jerking his head from side to side as he tried to back up.
Dawn gasped around the stone in her mouth as she felt the damned sock loosen, very slightly.
Dawn was so horny now that she was quivering all over. She watched intently as Tonto got a better grip on the sock with his huge gleaming white teeth. He wiggled his rear as he got himself placed, then, with a sudden tug, tore the knotted sock loose. Dawn quickly pulled her foot free of the wet loop of knee sock, let her legs close for a moment as she eased the throbbing pain in her thigh muscles.
She moaned loudly with the pleasure of lost pain.
But Tonto whirled around and nipped at her ankle. He waited a brief second, looking directly at Dawn's ankle. She didn't move. He opened his jaws, dove his big mouth down, and took a firm but gentle grip on the slimmest part of her girlish ankle. Dawn's eyes widened for a moment in fear. But then she watched in amazement as Tonto simply backed up, his tail giving a few quick wags. The dog dragged the girl's legs apart again.
Dawn expected the animal to step up between her legs, and start nuzzling her pussy again. But he didn't. Tonto stepped over to her other tied ankle and made quick work of loosening the twisted band of sock.
Dawn worked her ankle and foot free of the binding. She sighed through her nose. Her ankles were sore and throbbing, slightly red. She could plainly see the indentation in her flesh where the sock had been wound around her ankle, but she wasn't bleeding.
Tonto looked at the girl's face. His own face was handsome, beautiful. He cocked his head, as though waiting. A hard wave of lust swept through Dawn's whole body as she sat there, looking into Tonto's dark intelligent eyes.
Slowly, understanding instinctively what the dog wanted her to do, Dawn brought her heels up against her tight ass cheeks. She pushed her shoulders back as far as they would go, to give her some slight slack on the cord binding her wrists. Then, struggling hard, she forced herself to stand up. The cord behind the tree caught on the rough bark several times, forcing her to squat lower and start again. But finally, Dawn was standing on quivery legs, her back tight against the trunk of the big tree.
Tonto barked once. It was an obvious command. And Dawn obeyed instantly.
She squatted down a bit.
She spread her feet as far apart as they would go.
She arched her ass away from the tree trunk and thrust her whole body forward.
Tonto yipped.
She froze, held her pose tensely.
Her blouse hung down loosely around her sides, her belly and tits exposed. Her bra stayed twisted in a tight white cord of silk just under the lush globes of her beautiful young tits.
Her skirt slipped back down over her thighs, covering her ripped and shredded panties. She could feel the gooey fuck fluids from her oozing pussy sliding down the insides of her thighs.
She began quivering in her tensed position.
Tonto watched her closely, cocking his head from side to side.
Dawn looked down at the handsome beast. His nostrils were quivering. His tail wagged constantly. He looked to the bound young girl as though he was waiting for her to do something. Maybe she was supposed to give him some kind of command. But what kind? He sure hadn't needed any commands to free her legs.
Dawn gurgled in her throat. She suddenly saw it. Tonto had freed her legs, but he didn't know her wrists were tied behind the tree. He was waiting for her to lie down, not stand up. He was waiting for her to lie down on the ground and let him fuck her.
In that same flash of insight, Dawn realized that this amazing animal had fucked human girls before.
She could see it in his eyes, the way he watched her, the way he waited patiently for her to get ready.
The big dog hadn't needed a command to free her legs. What could that mean? Maybe that he'd been trained by some girl to untie her? Maybe that little creep Jimmy had a sister and tied her up a lot. And maybe Jimmy's sister had trained Tonto to untie her after Jimmy had left.
Dawn was amazed at her own sudden insight. She was certain she was right. It was just too much of a coincidence to meet a little kid who liked tying girls to trees, and then to meet that same little kid's dog, who knew how to untie girls from trees.
Untie girls from trees?
Dawn straightened up suddenly, and twisted her whole body. She tried to turn around, to shift around the tree trunk, so she could show her bound arms to the watching dog.
She gestured and grunted, indicating that Tonto should go around behind the fucking tree. If she hadn't had this damned gagging rock in her mouth, she could have just told Tonto what to do.
Dawn almost grinned around the stone in her mouth. Of course. If she wasn't gagged, she could command the dog to untie her wrists. That was what he was waiting for. He was only partly trained. He had to be told what to do, except for the tricks he'd already learned, like untying a girl's ankles.
