It had happened the first time that she rode her pony bareback. Bonny hadn't even been thinking naughty thoughts, she had simply been jogging along on Buck's broad back when all of a sudden, her cunt started to simmer, then smolder. She had wrapped her slender thighs tightly around his powerful, sweat-lathered body and squirmed her crotch up and down along the ridge of his spine until, gasping, she creamed. It had been so wonderful that she could hardly wait for her next ride.

Just at the moment her father was beating his cock thinking about Bonny, the girl was wriggling happily around on Buck's back. She had started to squirm the moment the bend in the lane had taken her out of sight of the field, moving sinuously and slowly, wanting to prolong the pleasant build-up before the creamy conclusion.

Her thighs tensed and her ass churned. She clung to the pony's flowing mane, her eyes narrowed and her lips parted, her pretty face transfigured to a mask of pure passion. She wasn't wearing any panties under her tiny denim shorts and the crotchband of those shorts was sodden. The material was dragged into the vee of her crotch as if by the suction of her cunt-hole, and her hairy, pink cuntlips were gaping open, pushing free of the band. Frothy white cuntjuice trickled down the insides of her thighs like a string of pearls.

Buck tossed his head up and snorted, his soft nostrils flaring and his eyes wild and white. He sniffed, scenting the girl's arousal and, being a stallion, started to get aroused himself. He trotted more slowly, his gait faltering as Bonny rubbed her crotch up and down along his ridged backbone.

A ribbon of pussy juice slid from Bonny's steaming cunt and poured down the pony's back. The hot slime was drenching her shorts and seeping through the denim, making the animal's back slippery and Bonny slid up and down on that lubrication, moaning softly as her wonderful sensations rose towards their peak.
