"Did you think you could get Married, and I would just what? Stop our relations? Just like that?" Fleamonts husky voice grunted into James' ear as his father steadily pressed his cock into him from behind. He could feel his dad's hair covered chest scruff against the smooth sin of his back, it was Wirey and widespread. He could smell the spicey scent of his father's cologne and feel the heat radiating off his body that matched his own, James' friends made fun of him for being a walking heater and it was certainly something he got from his dad.
"Dad no I didn't- Mphh" James was quickly silence by a large hand grabbing a fist full of his wild, Untamed brown hair and slamming his face with force down into the mattress below. His father was usually so kind to him, so loving and tender. James wasn't used to this side of him at all.
"You waltz into dinner and announce you got that red-haired girl pregnant. That I mercifully let go, but to come again and announce a sudden marriage?" Fleamont growled as he felt his cock bottom out inside his son's tight ass. It never loosened over the years no matter how many times he had used it. Maybe he took too good of care of his son, being too gentle allowed him to get silly ideas in his head, like he had free will to marry himself off to whoever he wanted or that he could try to leave the house.
James let out a cry, the bed below catching the drool that fell out of his mouth rather ungracefully as his dad shoved his way inside his unprepped asshole without mercy or even so much as a finger to ready him. "Dad! fuck! ow-" he whined, muffled by the quilt that smelled sweet like his mother, he must've been laying on her side.
Monty didn't move for a moment, squeezing his own eyes shut as he adjusted to his son's tight rim squeezing the life out of his member, almost painfully so. "Nng- god-" he grunted under his breath, moving one hand from his sons hip up to his glasses that had begun to fog over. He had the sense to remove James' before starting so he didn't have to buy him a new pair if he broke them with how rough he planned to be, but his own had slipped his mind until now. He tossed them off to the side, standing himself up on his knees to do so without letting his cock have any give from his boys ass.
"Daddy please-" James whimpered, hoping the nickname would earn him some mercy. His face turned to the side to look over his shoulder at his old man, "It wasn't like that dad- I love her."
"Did I say I wanted to hear your excuses?" Monty snapped, harsh enough to make James' slack jaw snap shut.
Fleamont panted a few times, the air of the room thick with unspoken words, questions, and tension. "Fine... you love her. But you're MY son, and you belong here under me." His hips kicked up into a medium pace, one that made James' mouth open again and a cry of pain leave his soft brown lips as he waited and mentally pleaded for his ass to relax and stop fighting the intrusion.
Fleamont couldn't keep his thoughts straight, he was beyond angry, he couldn't lose his son to a girl. He had loved his son in this way since he was in diapers, touching him, stimulating him, and fucking him as much as he desired. His mother had done the same, doing anything they could to pleasure their son and keep him happy. It was all James had known until he went to Hogwarts and met Sirius. Sirius had gone and put these ideas into James' head, that he could be with whoever he wanted and give himself away.
"Does she feel as good to you as I do, son? Hm? The only sex you've ever known is from Your mother and I, You were bred and raised to be a hole for my fucking use, and you're not getting out of that because you want to marry some bitch, Do you understand?" Fleamont snarled as he picked up his pace, ramming his anger out into the boy below him and smiling as he heard his son sob. It felt amazing, like he was properly punishing his spoiled brat of a boy.
When James didn't answer him, Monty could feel himself grow angrier.
"Dammit" he grunted, his large hand reached down and wrapped around James' throat, his thumb squeezing the side of his neck as he pulled him up. Monty was on his knees, sat back so James was upright and flush against him, cock sheathed inside his ass, skin stuck to skin, thighs to thighs and chest to his back, "I expect you to answer me when I ask you a question James" he huffed in his ear, taking this moment of reprieve to catch his breath. He was much older than he used to be, he really needed to get back in shape.
"I'm sorry daddy-" His son cooed, sounding small again, like the toddler that used to never want to leave his side.
Fleamont smiled, James could feel the curl of his lips against the curve of his ear, making his legs shake and nearly give out beneath him. "Goodboy. Let's try that again- You getting married does not reassign you to belong to her. You will always belong to your mother and I, is that clear?"
James let out an exhausted sounding chuckle that reverberated out of his throat. His Adams apple bobbed past the threshold of his father's grasp, " Dad I was never going to leave you." he said, his big brown eyes looking into those of his father. James was such a perfect mix of his own flesh and blood, it was like looking into a mirror. "Is that what you thought?"
Fleamont furrowed his brow, sitting them down on his heels for support as he searched his sons' eyes for any sign of dishonesty, "It is.... You're not?" He asked, voice much more caring than it had been moments before.
James brought his hand up, cupping the crux of his father's neck with a smile, "No- actually, I was hoping she could join us. I want to make the family bigger dad- not run away and leave you and mom behind," His hips wiggled on his father's lap, eager to feel him move once again.
Fleamont melted at his son's words and huffed, nestling his nose into James' jaw as he placed sloppy kisses along his stubbled, mature edges. He wasn't his little boy anymore, James was a man, maybe that is what really scared Monty.
His own hips began to pick up a slow pace with him, bucking soft and deep into his sons' ass, "You have no idea how happy I am to hear you say that son-"
James let out a few more pathetic moans, lifting his own hips and setting them back down with more fervor, needing to feel his dads seed inside him once more.
With bated breaths and stolen, sloppy kisses, they found a fast pace and fell into perfect sync with one another. "I can't- last much- Mmmmm," Monty groaned, whimpering a bit at the sound of his boys beautiful cries of delight. They were about to bring him over the edge.
"M-me too, Fuck please- please cum inside me dad," James begged, he needed his father to know he still belonged to him, that nothing would change, and he would always be his Daddies little boy.
All it took were 3 more snaps of his hips to feel himself release and watch as James came from the feeling of Monty's seed in his ass alone. He hadn't so much as brushed against the boy's penis the entire time. Fleamont could feel his heart swell with contentment at that, it meant his son still wanted him, still needed him, still loved him.
He let go of James' throat and laid down on his back on the bed with a smile, his wrist reached up to wipe the sweat off his forehead then he quickly turned onto his side to tuck James under his arm in a cuddle.
"Hey dad?" James' drained voice asked as he squirmed and twisted around to face his father.
"Yes?"
"When Harry is born, can you teach me to raise him like you and mum did with me?"
