Chapter 1

Marion Tremayne was startled when she realized that the horse she was riding was getting a hard-on.

Then she was thrilled.

She was riding bareback, and the thought that it must have been the rubbing of her hot crotch on his back which excited the horse was the sort of thing that thrilled the woman. Marion was a sexy woman who had often given men hard-ons, but this, as far as she knew, was the first time that she had ever excited an animal.

She looked ahead to where her guide was riding, leading the way. When she saw that he was looking straight ahead, she grinned and leaned sideways, staring down under the animal's loins.

His huge prick looped out in a fat prod.

The big, dark-fleshed cockhead was just starting to push out from the foreskin and his balls were big as melons.

Marion was getting turned on, herself.

She looked ahead again.

The young man who was guiding her along the forest trail was paying her no attention and had obviously not realized that her mount was sporting a stiffening prick.

Marion folded her legs in around the horse's flanks.

He was a sturdy horse, but not overly large, and she was able to touch both booted heels against the animal's cock. Her well- muscled thighs gripped the horse around the flanks, tightening and relaxing as if she were lasting at a trot. She began to rub her heels up and down the animal's huge, swollen prick.

It got bigger and bigger.

The head flared out in a great, mushroom-shaped slab of dark- gray cockmeat, throbbing. Marion could feel his prick pulsating between her heels. The woman wished that she were barefoot so that she could caress that lovely cock with her naked feet and calves.

The woman kept leaning down to gaze under the horse, then quickly looking ahead to make sure that the horse's condition and, more to the point, her own involvement and interest in that condition had not been noticed.

Marion would have been mortified if the young man had noticed what she was doing.

She felt a bit embarrassed by it, herself.

Yet that massive hunk of horsemeat was so thrilling that she wasn't worried about a silly thing like being embarrassed... as long as no one else knew about it.

The guide did not look back.

He was leading them along a narrow trail with trees on one side and a shalestone incline on the other, carefully picking his way around and under overhanging branches, concentrating on the path.

Marion massaged the horse's cock some more.

She began to wonder if she would be able to make the horse come like that, between her feet.

The instant that the possibility occurred to her, she felt an unholy urge to jack the beast, knowing what a thrill it would be to see his cum spurt out and know she had caused it. But she was nervous. What if the young man happened to look back just at the critical moment, when the horse was spurting his wad?

She looked ahead again.

Marion was flushed with lust and blushing with embarrassment because of that lust.

The young man, although she did not know it, was blushing, too.

He was a teenager, tall and lean, dressed in jeans and a plaid workshirt, boots and a Stetson. His name was Jake. He was blushing because he thought... and hoped... that there was a chance that sexy Marion Tremayne intended to seduce him.

Such things had happened to Jake before.

He worked on the dude ranch and, quite often, the women who took their vacations there were horny, and a few of them had seduced young Jake at the end of the trail.

In his tight Jeans, with his crotch-bulge evident, Jake was the sort who appealed to horny women of all ages.

But no one as gorgeous as Marion had ever stayed at the ranch before, and her very beauty made the boy nervous.

That was why he was not looking back.

In fact, it had been Marion's intention to seduce Jake.

This was her first day at the ranch. Right away, she had seen the way his cock bulged in his tight jeans and figured that she would make a play for him as soon as they stopped in some lovely and romantic spot along the trail.

Marion was a married woman and not particularly promiscuous, but she had come on this vacation without her husband and it was the sort of occasion when even a faithful wife was entitled to slip up, she figured. She had been thinking about seducing young Jake as she rode along bareback, and she had been getting hot.

She thought that maybe she would blow him first.

Marion liked lean, young men, and the thought of driving them wild with her tongue, hearing them whimper as she took their jism in her mouth, was inspirational.

Then, if he was as potent as he looked, she would let him fuck her as long and as hard as he wanted.

That had been her intention.

And perhaps it had been her sexual arousal that had inspired the horse to get an erection.

But now Marion found herself far more intrigued with the horse than with Jake.

Marion was a tall, willowy woman, with long, long legs. Those legs were wrapped firmly around the horse as she continued to stroke his prick between her heels.

She had an ass shaped like a valentine, and that ass was rubbing steadily on the animal's back as she worked her foaming crotch around on heated animal flesh.

The horse was slightly lathered.

Her cunt was lathered a lot more.

Marion's tits were large and firm and thrusting and, at the moment, her nipples stood out stiff and trembling against her shirt, swollen so much they seemed ready to explode.

She looked down again.

Her curly auburn hair cascaded over her cheek as she leaned far down over the horse's back and gazed at his cock. Her green eyes flared, hot as molten jade, thrilled by the sight. Her wide, full lips parted, panting, and the pink tip of her tongue slid across her mouth.

By this time, the horse's prick was hard as a rock and so taut that it was throbbing between her boots like a captive snake. She knew that it wouldn't take much more rubbing to bring the beast to a climax.
