"Oh, wow! Wow! This is fantastic… I… uhhhhhh… oh, wow!"
Marcie smiled. She could tell from her cousin's tone of voice the girl was about to cum! Kathy could never hold back. She had to have it all fast. And the horse was far from shooting his cum-load. To help her along, Marcie moved her head to one side, pressing her tongue along one cunt-lip and rubbing her tongue against both Kathy's cunt-lips and the animal's slimy prick. Both appreciated the added touch. The brunette gasped again, her fists hammering against the sides of the crates while the stallion whinnied again. What had come over Marcie? She didn't know. She was doing this instinctively, thinking about Byron, about the way his prick had felt in her mouth. Then she somehow transferred that feeling into the one that now drove her to lick her cousin's cunt and the horse's cock.
"Ohhhh, cummmminnnngggg!"
Kathy jerked and bounced against Marcie's mouth and the crates, her cunt snapping again and again against Tundra's prick. The horse didn't know what was going on. He snorted wildly, his hoofs stomping madly around in the hay. Apparently no mare had reacted the way Kathy was doing now, moaning and screaming while her pussy milked his cock.
Marcie waited until Kathy had calmed down and slipped her cunt from the animal's glossy prick.
"My turn," she said, fuck-lust making her voice tremble slightly.
"I thought you'd go for it," Kathy said weakly, pushing stray hairs from her face as she climbed off the crates.
"Your turn to help me, too."
"Wait till I catch my breath!" Kathy cried, putting one hand to her tits and inhaling hard.
In a moment she was ready, scurrying around to the other side of the horse. Tundra was confused, rearing back for a moment before Kathy soothed his nerves.
"Steady, steady, boy," Marcie whispered, crawling onto the crates and assuming the crouched position her cousin had taken earlier.
"Okay, Marcie, get ready for it… and it's wild!"
Marcie hugged the crates, feeling the rough wool of the horse blanket scratching her tit flesh. She raised her ass a little, loving the sensation of the powerful horse towering over her. She saw his front legs move around her, smelled the sour odor of his crotch as his hard cock neared her pussy.
And then… and then she felt it, the hard, slick, hot touch of the horse's cockhead flattening her swollen cunt-lips. She thought of the handsome stallion, of his shiny black skin, of his handsome head, and she dissolved in a frenzy of lust. Fucked by a horse! She laughed, tossing her head from side to side, her hair whipping over her whitened knuckles. Kathy was guiding the horse's cock. The pressure increased. Marcie felt her cunt-lips sink inward.
"Ohhhhh!"
The girl cinched her eyes shut, breathing with wheezing, gasping sounds through her flared, burning nostrils. She felt the horsecock fucking into her cunt. Oh yes, she felt the animal's fat fucker pushing at her cuntal walls, fucking into her hot, juicy pussy. Marcie groaned, hearing the big cock slurping its way in.
"Ohhhhh, it's so good, so good!"
Hot, shivery flashes of sexual heat rippled through her cunt, forcing the pussy muscles to tighten around the fucking cock, then loosen to admit more. The horse whined and snorted again and again, stomping around her, but keeping his prick always inside her pussy. He was fucking more and more of his cock into her. And Kathy was there, guiding him, rubbing his balls, exciting the stallion even more.
"Wow, it's somethin' else, watching his prick go into you, Marcie!"
"Uhhhhhh…"
Her breathing was coming in pants. Sweat dripped off her tits as her nipples rubbed against the scratchy wool blanket. Marcie groaned, twisting around as much as she could. She was being split open by that animal-cock. And she loved it.
"Fuck, fuck, fuck," she pleaded as the horse began pumping his powerful hindquarters back and forth.
Her cunt got hot under his constant attack, the pussy juice boiling up from her fuck hole. She was full of the horse's cockmeat, stuffed with his gigantic black prick. Marcie felt his cock tighten into an iron rod. His cock vibrated in her pussy. She knew Tundra was about to shoot!
"Ohhhhhh, slow, slow, slow!"
But the horse wouldn't stop. He fucked his cock faster and faster into her pussy. She could feel his flared cockhead slamming hard into the bottom of her strained pussy now and began to fear that the snorting animal would injure her. The horse let out a funny groaning snort.
Then Marcie felt the horse suddenly stand very still. His cock was sending stream after stream of hot cum deep into her tender tight cunt. She could feel his cum-load jet out and burn its way through her cunt. Tundra's cockhead was sending incredible thick gushes of horse-jizz into her body. She couldn't hold out.
With a scream, Marcie crashed into the world of climax. "Eaghghghhgghhhh!"
Her cunt squeezed tightly, clutching along the horse's cock while her body exploded again and again. She cried out as she felt the final throbbing of the stallion's prick shoot out another load of horse-cum into her hot fuck hole. After the fourth explosion Marcie collapsed onto the crates. Just like the dog, Tundra pulled his cock out quickly, stomping against the back of his stall while bobbing his handsome head up and down.
"Wow, Marcie. You sure learned a lot here on your vacation!"
Marcie lay draped like a limp rag over the boxes for another minute or so, feeling the cum drip from her gaping pussy onto her thighs. She had done it, gone all the way, fucking her cousin Byron, fucking the dog, then finally… finally fucking the horse!
She had done all those things. And yet, strangely, she felt not one ounce of guilt. Pushing herself up from the crates, Marcie steadied herself, picking up one edge of the blanket and dabbing her cum-smeared cunt gently while staring at the stallion.
"Oh, Kathy, that was so good! It really was," she confessed, breathless with excitement.
"I know. And you've got two more weeks here! It's going to be fantastic having you here. And I know Pardner's going to like it too, and Tundra as well," Kathy said, nodding in the direction of the stall.
Marcie shivered, smiling weakly as she helped her cousin put away the crates and blanket. The two girls cleaned up as best they could, occasionally stealing glances at the penned beast behind them. Marcie had tried so many daringly new things. All of them she had liked and she wanted more of the same. Thoughts of fucking the dog, of fucking Byron and fucking Tundra drifted through her mind as she pulled on her skirt and started to leave the barn.
"What a summer vacation this is going to be, Marcie!" Kathy said, hugging her cousin tightly after they had slipped from the large barn.
"Yes," Marcie agreed breathlessly, staring at the big house in front of her and wondering what Byron was doing.
What would fucking Byron be like after having been fucked by the horse? She would have to try fucking Byron again. She might fuck them all again – the dog, the horse and her cousin – before her vacation was over. Why not?
