Josh stared through the windshield at the faded barn across the field. He desperately wanted to make this happen, but he was paralyzed with fear. His heart was racing as he took several deep breaths, opened the door, and he got his legs to move. He steadily made his way through the grass toward the building. As he got closer, Josh could see the rotting walls that showed the building's age and lack of use. This was the perfect spot to test the waters.
Looking around one last time, Josh made sure no one else was in the area, then turned the corner to the back of the barn. He saw a couple of old bales of hay against the barn wall. Josh leaned against them and started rubbing his crotch. His nerves fell away as his cock engorged, getting increasingly stiffer in his jeans. Soon the outline of his penis was visibly straining under the denim and Josh was stroking its outline, moaning slightly as the pleasure radiated throughout his body. This is what he had been craving ever since he tumbled down that rabbit hole of public masturbation videos.
Josh leaned his head back against the wall and mindlessly unbuckled his belt, sliding his jeans down around his ankles. His cock sprang up and bobbed as precum dripped from the tip to the ground. He gripped it tightly and thrust his hips into the closed fist, arching his back to push as hard as he could. His head was reeling! Thrusting and pumping, his penis felt harder than he had ever felt. Josh was aware of every sensation between his cock and his hand. Gripping it tighter, he felt a swelling in his groin as his balls pulled closer to his body. "No!" he thought. "Not yet." He edged the feeling in his groin and slowed himself. That's when he noticed the low vibration on the barn's wall.
His cock dripping and going limp in his hand, Josh stuffed himself back into his pants leaving them unzipped and his belt unbuckled. He pressed his ear to the wall. He heard a low hum and faint intermittent hissing. "This was a retired farm", he thought. There shouldn't be any activity in there. Josh crept along the barn wall turning around the corner. It was only now that he saw the alternate driveway and entrance. A van was parked haphazardly. It had no markings and very dark tint on the windows. Something inside him felt compelled. He knew he should leave before he was noticed, but he was still aroused by masturbating out in the open with people nearby.
Josh continued along the wall and slipped inside a door entering a short hallway. The noises were more audible from this side of the building, but he now heard men talking and what sounds like moaning. His penis instantly responded as he recognized the sounds. He didn't know what was happening in the dilapidated barn, but it was something he needed to see. Josh closed his eyes, made the decision to proceed, then turned to go further.
Peering from behind the wall, he took in the scene. There were two men standing together. They were relatively tall and burly. One was dressed in a plaid shirt and overalls with the straps hanging from his waist. The other, in jeans with no shirt. "These guys look like farmers." Josh thought to himself. They stood there talking in low voices about how good the bulls were doing and occasionally one would grab their crotch. Beyond the farmers, naked men were strapped to wood framing. Each man was standing on a wooden platform with legs apart, arms above his head, and slightly leaned forward.
Without realizing, Josh had begun stroking his cock again, watching the scene. "Bulls!" he whispered. The men were being milked! He again, noticed the hissing he heard through the wall. Its rhythm matched a stroking motion of dairy milking tubes strapped to each man's penis. His own stroking synchronized with the milking.
One of the men started moaning louder and the farmers made their way to him. "I'll check the output while you tend to our bull, John." said the man in the overalls. With that, he crouched down and lifted a hose leading from the bull's penis, down the row to the machinery making all the noise. John stepped up onto the framing and grabbed the man by the chin, turning his head toward him. "Good bull!" John said to the man, through gritted teeth. "Give up that seed."
