Concrete Bottom

Chris was confused when he arrived at the location texted to him. He had been talking to a sexy construction worker on an app, hitting it off after seeing him for the first time in the area. Agreeing to hookup, Chris prepared, headed to the address he'd been texted.

He arrived to find an empty construction sight, the work day already over. He was about to pull out his phone when he felt a hand on his shoulder.

"Hey sexy"

Chris turned, smiling once he saw their face. The man was masculine and more handsome than his pictures. He was rather large and taller, still in construction garb, his figure built from clearly having spent days working on site. He smiled a toothy grin looking down. Chris couldn't help but feel his heart beat faster, loving being this close. He could even smell the day of work still on him.

"Couldn't wait to get a piece of this ass." The man said, grabbing Chris's rear. Chris felt himself turn red.

Let's head in" The man said, pushing Chris toward an open gate.

Chris walked into the new building, exposed layers of concrete lit by the construction lights hanging from the ceiling. He couldn't help but feel nervous, but the lighting almost made it more romantic. The big guy was hot in Chris's tail, pulling them out of sight from the street before beginning to strip.

In moments Chris was in his jockstrap and harness he'd worn under his clothes, wrapped tightly by the straps as the man whistled in admiration. The man reached out to graze the open skin, quickly sending chills through Chris's body from the touch. The man's gaze turned hungry, looking down at Chris like an animal.

"Kneel boy" He demanded, a playful twinkle behind his eye.

Chris moved robotically, quickly getting to the ground in full display.

"Oh fuck, looking good boy" The man said, putting something on his hands before beginning to massage Chris's ass with it. It was a cold fluid, reminding Chris of lube, but the chill of the touch only made Chris's bottom more sensitive, his body beginning to tremble in his position. He let out a quiet moan as the man's slickened fingers slipped into the crack, opening up Chris's loose hole before withdrawing.

"You're such a good boy" The man said, guiding his hard cock right into Chris's cavity. Chris felt the rod move in steadily, shifting through his insides as his tight hole wrapped around it. He felt electricity begin to flood his system as the man thrusted deeper, building up pace until Chris was having trouble holding himself up. He felt his rear weaken, letting the man further and further into his hole as he lost control of his throat, moaning at every pulse inside him. Soon his entire body was moving with each thrust, his body trembling as endorphins flooded through his system before a burst of warmth washed his groin.

He lay there for a moment panting, hearing the breathing heavily behind him as he pulled his rod out. Chris stayed still for a moment, recovering before trying to stand- only to realize he couldn't.

"What the fuck?" Chris said, trying to move from his position. He didn't know what it was, but it felt like his rear had become solid, reminding him of being in a cast. The strangest part was he could still feel his hole gaping, filled by something even though the man had already pulled out. He tried to look down to see what it was only to realize his body no longer had any hair, his pale whiteness matching the smooth concrete underneath him.

Chris felt his ass slapped again, but it didn't move. He felt the cold touch of lube again as the man began applying the solution again.

"What the fuck is that stuff?" Chris said, his voice shaking.

"Ah this? Just a little concrete solution I came up with. Helps me stay rock hard and my boy's hole wide. Don't worry it wears off, but in the meantime, you'll be my perfect bottom bitch." He said, finishing with another slap.

"Get the fuck off me!" Chris shouted, using all his strength to try to break free. "Don't make me shout for help!"

The man laughed, quickly slapping his hand over Chris's mouth and applying a generous amount of the solution. "Don't worry, this should help you stay silent"

Chris did his best to make a noise, get anything past the meaty hand, but it was useless. The man held Chris's mouth closed until the same paralyzed feeling had taken over his face. Chris could only make muffled noises as the man lined his cock up again, plunging it into the already widened hole.

Chris felt his mind rocked by waves of ecstasy, his eyes rolling up into his head as he accepted his position for the night. He didn't know when it ended or how many loads had been put into him, but by the time it was over he couldn't move even if he wanted to.
