The rider's legs were aching. He had been standing in the stirrups for nearly forty minutes. The owner would not stop the horse; he carried on guiding it in a figure of eight around the riding hall.
The rider tried to lean back again. His hips and knees were strapped firmly in place. His wrists were lashed to the saddle horn. He could not avoid the dildo that stuck up from the seat. It pushed slickly between his buttocks.
The rider stood straight. He would not let himself be humiliated like that. His leg muscles trembled.
The owner looked over his shoulder. His gaze slid up the rider's leather chaps and settled on his naked crotch. The rider was semi-erect, and hated himself for it. The owner looked smug.
"Only another twenty minutes left of your lesson, mister." The owner said. Then, "Hutt!" and tugged the reins. The horse picked up its feet and started to trot.
The rider had taken a few lessons along with his wife. He knew the best way to ride through a trot was to bob up and down with the motion of the horse.
He kept his knees locked straight. After half a loop of the hall at a fast trot, they began to give out. He was an experienced swimmer, but he found he didn't have the stamina to hold this position.
With every second step, he was forced against the dildo. It pushed into his manhood, threatening to take it away.
He felt himself grow more open and more eager each time.
Horse, owner and rider were alone in the hall. From just outside the open-air end, with one arm over the fence, the stable hand watched. He rested a foot on a crossbeam. His jeans were open, shucked down over his buttocks. The stable hand rested his balls on another crossbeam and pulled at his own cock through his underwear. The head of his cock was starting to make a wet spot where it pushed against the cotton.
The stable hand had warned the rider there would be consequences if his wife's dressage lessons went unpaid for. The rider had not taken the warning seriously. Now he was paying with a "lesson" of his own.
The rider's legs shook uncontrollably. He tried to put more weight on his wrists, but the cable ties cut cruelty into his skin. He sucked in air, wracked by pain. His feet shook in the stirrups. Sweat rolled down his naked back, under the leather belt and between his buttocks.
The tip of the dildo pushed up into him. He grunted through the gag and jerked himself forward to avoid the dildo getting any further.
As he did so, his left foot slipped from its stirrup. The rig of straps and belts stopped him shifting sideways. Instead he fell down onto the dildo. It penetrated him forcefully.
The rider moaned loudly. He had expected pain. His wife had complained of it, that one time. But he had been goaded for so long, and he was so tired, that there was no resistance. The dildo slid thick and solid inside him.
His cock jerked up, fully hard.
The owner hauled the horse to a slow walk. He was panting from running alongside the horse, and his white shirt was clinging damp against his chest. He turned and reached up to the rider, gripping the rider's cock between finger and thumb. He ran his thumb up the underside of the rider's cock. The rider tried to wriggle away, but only ended up grinding onto the dildo. Precum flowed onto the owner's thumb.
The owner brought his thumb to his mouth and licked it. He turned and took the horse back up to a trot. As they picked up speed, he adjusted himself.
The rider tried to stand again, to get off the dildo. It rubbed inside him, making him suck on the gag. He only got halfway up. His legs could not hold his weight any more. He lowered himself onto the dildo, trying not to enjoy it.
He sat with it filling him up, slowly rocking with the motion of the horse. His cock bounced heavily on his balls.
The owner tugged on the reins again, and they trotted faster. The rider was powerless to resist the motion of the horse now. He sat still, but the saddle slapped rhythmically against his buttocks, drilling the dildo into him. He felt pressure building at the base of his cock.
He decided to follow his lessons, to try to hold off an orgasm. He did not want to give the owner or the stable hand the satisfaction of forcing him to cum. The rider half-stood in the stirrups every other step. He rode up the dildo, and slid back down onto it, rose up and slipped down, again and again.
His ass was alight with pleasure. With every rise and fall his breathing grew heavier. The dildo plunged in and out, in and out.
He clenched it involuntarily. His cock smacked against his taut stomach. He didn't want to stop.
