Work Text:
William was cleaning his son’s room – he really had to stop, Kyle was old enough by now to do it himself – when he lifted the mattress to change the sheets. Underneath, he found something unexpected. His own boxer shorts, the ones he’d known he put into the laundry basket after a long, hot day of hard work. He lifted them up and tentatively sniffed them. He smelled himself, of course, but also something else, something musky but unlike him. Had his son been masturbating with his underwear?
He had to investigate more. He logged into his son’s computer. The browser history was turned off, but after rooting around a bit, he found a folder – labelled “homework”, of course – that had porno videos. He clicked on one.
A man, probably about William’s age, was fucking another man, who didn’t look much older than 20. He watched as they fucked hard, and then, unexpectedly, the younger man began to call the other “dad”. Not “daddy”, but “dad”.
Will clicked on another video and found the same thing. All of them were the same theme, a large age gap and assumed incest. He watched every video, not sure what to do, and not noticing his cock hardening in his pants. He clicked on the last item, a new folder, and was shocked again.
It was naked photographs. He didn’t recognise the first few, headless shots of a man’s hairy body while wearing a binder, and a hairy pussy with a fat t-dick. But the next few had a face- Kyle. It was his own son.
He couldn’t take it any more. Will pulled out his cock and stroked it, going through each photo slowly, making sure to take it all in. Each one was more slutty than the last. He saw his son’s spread pussy, his asshole gaped on sex toys. There was a picture of him double-stuffed on dildos, one in his ass and one in his pussy. Will wondered where he got the toys from. In the final few pictures, Kyle had shoved items into his holes – the handle of his dad’s hairbrush, the tv remove, his deodorant can. Will briefly had a thought that none of them were as thick as his cock, but he pushed it out of his mind.
Suddenly, the door opened. Kyle was home early. He must have not heard the door open. Before Will had time to panic, Kyle had crossed the distance to his desk.
“Hey dad. Do you like the pics?” He reached for his cock.
William grabbed his hand. “We can’t- it’s not right.”
Kyle laughed. “Dad, I’ve seen how you look at me. It’s okay.” He smiled.
William slowly released his hand, but still looked fearfully at his son. He watched as he brushed his fingers over Will’s length, and he shivered hard. It had been so long since he’d had this. Kyle sank to his knees and kissed his dad’s tip, earning him a gasp. He licked up and down the thick member, making sure to pay special attention to his frenulum, licking it hard a few times. He sucked on the tip and licked it with his tongue for a while, looking up and locking eyes with his dad.
William moaned. He patted his son’s soft hair as he watched in disbelief. How was he so good at this? He couldn’t even think, sitting back and enjoying it. When his son moved forward to slowly throat it, William had to hold back from shooting his load right there. He let his son bob his head up and down a few times, never once hitting a gag reflex, until Will suddenly lost control and spilled ropes of cum into his son’s mouth. Kyle swallowed without missing a beat.
“Holy shit. How did you learn to do that?” William watched as Kyle licked his lips slowly.
“I’ve been going to truck stops every weekend” Kyle said simply.
Will shook his head. He hadn’t been going to visit his friends, he’d been sucking anonymous cock in dirty bathrooms. He’d raised a whore.
“Alright, I need to go take a leak” Will tried to stand up, but Kyle didn’t let him. He pushed him back down and took his cock in his mouth again. “Kyle- what are you-”
Kyle sucked lightly on his tip until he saw his dad begin to realise what he wanted to do.
Will took a deep breath. “Are you sure you want to do that?” He had to admit, he’d thought about that a lot, but not with him. Kyle simply sucked harder in response.
His cock made his mind up for him. A few droplets of piss leaked out, and Will relaxed into it. The stream came out faster than he had intended to at first, but Kyle drank it all down like a champ, gulping down his dad’s salty fluid better than any toilet. He continued even when Will was sure it would be too much, the seconds stretching into minutes and his stomach beginning to distend.
“Goddamn. You practice that too?” Will wasn’t sure if he wanted a response, but Kyle’s nod when he pulled back made his cock twitch.
“Thanks, dad.” Kyle thanked him. For being his urinal. What the fuck?
Kyle got up to leave, but it was Will’s turn to stop him. “Hey. Have you ever gone any further than that?”
At first Kyle looked at him with confusion, until he felt his dad reach around and squeezed his ass. He shook his head. “I’ve sucked dick but I’m still a virgin.” The look in his dad’s eye was unmistakable.
They both moved to Kyle’s bed without a word. He laid on his back and let Will tug his jeans off, and he laughed when he found him without underwear and with a butt plug in his ass. He opened the top drawer to the right of the bed and, sure enough, found a large container of lube.
Will pulled the fat plug out of his son’s ass slowly, almost agonisingly slowly. When it was almost out, he fucked it back in a few times. Kyle whined.
Kyle watched his dad drizzle a generous amount of lube onto his cock and fingers, and shivered when the cold liquid was dripped onto his hole. His dad fucked two of his fingers into Kyle’s hole, easily sliding them in. His fingers were thick, but the plug had kept him nice and loose. After a few shallow thrusts, William pulled back and stroked his cock. He moved forward, lined himself up, and pushed in.
They both moaned. Kyle had never taken anything this big, and William was overwhelmed by how his son’s insides pulled him in, his warmth milking his cock so nicely. He moved his hips a little, building up speed and depth, obsessed with how his son’s asshole felt around him.
Kyle put his legs on his dad’s shoulder and moved with his dad’s thrusts, groaning as he was split open. He moved his hand to play with his t-dick but Will grabbed his wrists and pinned them above him. He changed his pace, suddenly fucking Kyle hard and fast, causing him to almost wail as he took the full length of his own dad’s dick into his warmth again and again. He felt it rub against somewhere good deep inside him and rolled his eyes back into his head as he came, whining “daddy” under his breath again and again.
But Will kept going. He fucked his son through his orgasm and into another one before he felt himself getting close, Kyle’s asshole suckling hard on his cock as it clenched down, his body shaking with overstimulation. His last few thrusts were hard enough that he though he might break his son’s hips before he came with a shout.
Will felt a warm trickle on his belly and looked down to see his son pissing from his third orgasm. He smiled and watched as it dripped onto the bed, staining the sheets permanently with the memory of their first time together.
Right then, they both knew that they had to do this again.
