Step Father Interference

Austin didn’t want to do anything. It was winter break and he didn’t want to spend it working or even going out. Sitting on the couch just vegging out to some video games and movies sounded better than anything else he could think of. He let his hefty guy hang out in front of him while he leaned deeper into his chair, watching anime. 

“Austin!” his mother called from upstairs. 

“WHAT!” he shouted back.

“I’ll be leaving for a few hours. Be good to your father!” she shouted down the stairs.

“He’s not even my dad…” Austin grunted as he ignored his mother. “Long as the bitch stays out of my way doesn’t fucking matter anyway.” However despite the long hours of anime he could watch; his snacks wouldn’t last as long. He got up and headed for the kitchen. His step father was currently playing on his phone. “Sup Dick,” he said condescendingly.

His step dad just seemed to ignore him. Far more concentrated on whatever was on his phone than Austin. “What was that?” even trying to sound threatening Richard wasn’t very good at it. His more soft spoken nature made him easy to manipulate with a stern voice. 

“Good evening sir,” Austin repeated. As he opened the fridge he caught himself saying something different. His confused look was enough to give Richard a smile. 

“It worked,” Richard smiled at his phone. “It really really worked. I thought it was just some dumb joke but it actually worked!” 

“What are you talking about?” Richard gave Austin a look. “Sir?”

“Nothing you need to really worry about. But your little attitude is going to change,” Richard smiled. “I wanna try something else first…” He went away typing at his phone. Something inside Austin was telling him to run but he had no idea where to run to. How could something make him want to call his step dad sir? The painfully wimpy guy was worse off than him but he now had something inside him saying that he needed to respect his authority. More importantly, why was he starting to get a little hard thinking about it.

But now it felt like his eyes were starting to play tricks on him. The scrawny little guy currently sitting in the chair didn’t look the same. It was hard for Austin to pinpoint what it was but he looked bigger. His short 5’6” frame filled the chair he was sitting in differently. Even he seemed to be amazed and confused as he looked down at his arms as they bulked up with a very dense muscle. His pecs pushed out against his shirt and even a few abs could be seen under the fabric. He moved around as his jeans looked painted on around his massive thighs and calves. He was growing. He stood up and stretched his new body to the sky.

“Holy shit!” his deep voice resonated off walls. There was almost a southern twang to it. Everything about him oozed masculinity. A full beard covered his face, trimmed to perfection. His hair was cut short and molded perfectly to his head. “This is fucking sweet!” he was still checking out his sexy body. His strong muscular ass pushed the jeans to the limits but the bulge in front was impossible to miss. His jeans cupped that thick hard dick, creating a perfect outline of it.

Austin found himself staring. His hand swiped across his own at a sudden idea that went through his mind. He scolded himself but that only seemed to turn him on even more. “What’s going on, sir?” he asked, trying to make sense of what was currently happening. However blood kept flowing to the wrong head. He couldn’t think about anything other than Richard. That shirt that was a size too small or the pants that wrapped so tightly around his body it left absolutely nothing to the imagination. 

Richard let out a hearty laugh. His massive pecs bounced with one. “I guess you wouldn’t know would you. I kind of made it that way. Supposedly everyone else will see this as though it was always that way. Judging by the pictures on the mantel I’d say it worked. Looks like you’ve got quite a few little half-brothers.” 

“Huh?” Austin looked at the pictures behind him seeing the trips to theme parks with full family instead of just him and his mom. Apparently he’d gotten really busy with mom, right when they had gotten married. But that wasn’t the same mother he knew either. Despite having so many kids she somehow kept her thin waist and looked incredibly active. But more importantly she seemed to have a genuine smile around Richard. What had always looked forced or unwanted was natural as she pulled deeper into hugs and took goofier pictures with her significant other. 

“I changed a few other things,” Richard gloated as he pulled out his phone again. “Hope you don’t mind. However problem is I’m still really horny. Apparently in this time line we made a deal that we wouldn’t have sex as often… But you know… We didn’t say that I couldn’t have sex.”

Austin’s dick went fully hard at the implication. Seeing his step dad’s giant body moving closer to him was just too much. He held himself up on the counter trying to keep from falling down. But there was just too much going on in front of him. Each step in his large brown boots, sent a shiver down his spine. The loud dull echo on the kitchen floor filled him with anticipation. Seeing Richard’s shirt and pants about to tear at the seams from just wearing them was too much. He did everything in his power to keep from falling over.

“Isn’t that right?” his hand gripped Austin’s fat shoulder. “Buddy.”

Austin’s ass tingled at the sensation. Knees nearly buckling to the floor. He was still fighting his current desire. Trying not to turn himself around and drop his pants right then and there. But he couldn’t hold out. Richard’s strong grip nudged him along. Slowly turning his large body around. Austin’s weight shifted to the counter as he leaned forward, exposing his asshole, trying to make it as wide as possible for entry. Richard’s thick cock pressed up against his quivering hole. He pushed in.

Austin let out a deep grunt. His face grimaced at the sudden intrusion. He didn’t want it to stop. His step father just kept thrusting into him. The fat cock opened him up even more. He tried to keep his body steady but with each thrust he was losing his grip. Richard just kept getting louder. His brazen satisfaction echoed through the house as he just kept going. Austin felt satisfied by this. His hand kept running over his dick as he was being used by the other man.

“Whose you’re daddy?” Richard grunted out. His hand gripped Austin’s shoulder even tighter.

It was hard for Austin to concentrate. “You are…” he grunted out.

“Louder,” he ordered.

“You are.”

“Louder!”

“You are!” Austin screamed and he could feel his ass fill with a warm liquid. Richard had thrust several more times into his ass as he just kept cumming. His muscular weight leaned down into Austin’s back.

“That’s a good boy,” he whispered in his ear. His big hand slapped Austin condescendingly across the face. “That’s a good boy,” he repeated as he pulled himself out of Austin’s ass. “Now go get yourself cleaned up.”

Austin did his best to make it to the bathroom before any of his step father’s cum started leaking out of him. He sat on the toilet trying to clean himself up. “What the fuck..?” he groaned. A hand went to his forehead as he tried to take in what had just happened. “I just had sex with…” his body stiffened and he could feel himself cum into the toilet. Several small bursts of cum shot directly into the bowl. It took him a second to realize what had just happened. But then the doorbell rang.

“Good afternoon Dillon. What brings you here today?” he could hear Richard answering the door.
