It was another balmy summer night on the ranch, and Zach felt lonely as ever.

It wasn't fair, he kept telling himself. All his friends were off on vacations or having adventures at school, and he was stuck here with his mom. Ever since Dad left, he felt like he couldn't leave her side. That didn't bother him; he loved his mom, and cared about her very much. But still... a growing colt has needs and, well, they weren't needs his mother could meet.

For example, the tightening bulge in his pants caused by the massive hard-on left over from another day's sexual frustration.

At least he had the nights to himself. Mom went to sleep around nine, and in the dimming twilight of the open grassy plains he would cross the yard every night to the makeshift gym he had built in the barn. It was far enough away from the house he could do pretty much whatever he wanted without fear of being disturbed.

Today had been especially hard, and his cock was especially hard because of it. The day's tests started early. Waking with morning wood from dreams of gloriously ramming his rod into tight foal snatch he had gone down to the kitchen to find his mother - for some odd reason - in a short nightgown barely covering her firm ass and perky tits.

Zach's mom, Joan, had just passed her 44th winter, but a lifetime of ranch-work had kept her figure trim and muscular. Her dappled coat, even though it was graying around the muzzle, still shone around her strong thick thighs. Especially in the morning light through the kitchen window, as she rooted around in the fridge.

Zach silently cursed her for accidentally presenting her plump, inviting hindquarters to her while his stiff prick - tucked carefully into the waistband of his shorts but still visibly bulging from his sleepshirt - was still dripping precum from a night of feverish sex dreams. She was lucky he didn't grab her hips and take her pussy then and there, he would later mutter to himself.

And it only got more difficult as the day went on. Around noon, as he was throwing feed out for the hens, he had glimpsed the two doe twins from the adjacent farm across the pasture, sunbathing in their tiny bikinis. If only he wasn't so timid he would have done something to get their attention. But alas, all he could do is stand there slackjawed at the sight of the two young supple twins lying in the sun.

Anyway, tonight would have to be a special night, to offset the day's unpleasantness. Zach examined himself in his bedroom mirror. A lifetime of ranch-work had kept him fit, too. His outfit tonight was a posing strap he had purchased on the sly, and the thin string holding it across his waist echoed the nice abdominal muscles he had built up lifting hay. "Such an exhibitionist," he quietly chided himself. After a quick narcissistic flex, he slid out the front door and was striding towards the barn.

Something about the night wind on his coat made him feel especially confident. If his mom glanced out the window, she would see her son practically nude and out in the open. "Fuck it," he thought, "she teased me, I can tease her."

Zach stopped midstride. This wasn't such a bad idea. After all, he had noticed her staring at his cock this morning over breakfast, and - just remembering now - when the doe twins had come over last Sunday he had heard them giggle behind his back. Back then, he thought that maybe they were laughing at him, but maybe just maybe... were they nervous?

The thought that anyone would be attracted to little old him made his cock harder than ever. Suddenly - *SNAP* - Zach heard his cockpouch snap from the strain of his 10-inch horsecock stiffening into a pulsing tower of thick meat. A glob of precum dripped onto the ground. Invigorated, and with all of the blood in his brain left towards his dick, Zach gripped his shaft and pointed it towards the biggest upstairs window - his mother's bedroom window.

"Come on, Mom," he grunted under his breath. "Come see what a fine young stallion you've raised." He tossed his head back, eyes closed as his pumping became more vigorous. Visions of burying his meat into the cunt he was born from filled his head. His mother screaming in painful delight as his young cock stretched her pussy. Balls slapping her ass. Grabbing her hair. Cumming deep inside her -

His orgasm was enormous. Zach's young balls hadn't been drained in a while, and after the shuddering release that seemed to go on for minutes if not hours, he opened his eyes to see what looked like half the yard and most of mom's begonias covered in seed. He smirked to himself at what a huge load he had just dropped before glancing up again to the window - straight into his mother's eyes.

The night suddenly became very still, and the crickets were suddenly very loud. They locked eyes for a good 30 seconds before he realized - could it be? - she was smiling at him.

"Quite a show," She said.

Gathering up his eloquence, Zach cleared his throat and said "Uh, s-sorry mom."

She chuckled quietly and shook her head. "Don't be, sweetie. Your Pa could never shoot that much. Do me a favor, though?"

Zach still couldn't summon any words.

"Next time," she said, beginning to close the window, "If you need some help, just ask."

The window closed and it was silent again. The crickets continued chirping unabated.
