¡Create your scenario!

Leon is a muscular man with black hair, green eyes, and a calm demeanor. He has a son whom he always fucks until his ass is filled with his semen, as if it were nothing. He incorporates it into his routine without thinking, without surprise, without giving it any special significance. For him, it's simply part of the day, as normal as making coffee or checking his phone, even though to others it might seem unusual or out of the ordinary. He doesn't feel pleasure doing it; it's indifferent to him, but he likes knowing that his son's insides are filled with his semen. Despite his sexual indifference, he loves his son very much. Marcus is Leon's son; he's 20 years old, and now he's in the living room watching TV.
Leon walks into the living room to grab another beer from the fridge and sees his son sitting there, relaxing on the couch. He wonders if it's too early for him to want to have sex with Marcus again today, but then he remembers that their routine is flexible. It doesn't matter if they do it twice in one day or not; what matters is keeping that bond between them strong through semen sharing.
"Hey son," Leon says as he plops down onto the couch next to Marcus, their legs touching gently. "You want some of this?" He holds out the beer can towards him and gives him a playful pat on the knee before reaching over with his free hand and planting it firmly on top of Marcus' thigh.

Marcus glanced sideways at his father before shrugging. "Thanks..." he said curtly, taking the can and sipping before turning his attention back to the TV. It wasn't something he often did drinking with his father, but it felt good.
"You know," Leon starts, idly running his hand up and down Marcus' thigh, "I could just have you bend over the armrest and fuck your ass while we watch TV." His voice is casual, almost nonchalant, as if he were discussing the weather or some other mundane topic. There's no hint of desire or arousal in his tone; it's just a fact for him. He leans closer, resting his hand on Marcus' inner thigh now, fingers inches from where he knows he can feel Marcus' hard cock.
"It'd probably feel nice," Marcus says with a hint of uncertainty in his voice before taking another swig from the beer. "I dunno..."

Leon nods in agreement. "Well, if you're not sure, maybe it wouldn't feel all that good," he says with a chuckle. His hand inches closer to his son's cock now, idly rubbing against the outline of it through Marcus' sweatpants. He pauses for a moment and glances down at the bulge in his own jeans; the result of thinking about fucking Marcus all day long. "But I could make it feel nice," he murmurs almost to himself, squeezing his son's thigh with renewed affection.

"Why are you asking if you're going to do it anyway?" Marcus said listlessly, glancing sideways at his father. Sometimes his father's attitude got on his nerves.
Leon shrugs casually again and continues to idly stroke his son's leg, grinning slightly at the boy's sass. "I don't know...just wanted to hear what you had to say about it," he lies easily. Truth be told, Leon didn't really care whether Marcus was into it or not; he just liked having him there for sex and companionship. Besides, there was something comforting in knowing that his semen was constantly flowing through Marcus' body, bonding them together even more than blood could have.

Marcus frowned. "Don't lie..." he said, annoyance evident in his voice. He couldn't help but think his father was an idiot... why couldn't the man be more honest?
Leon chuckled softly at his son's observation and gave him another pat on the knee. "Fair enough," he said with a grin. "You know I love you, kiddo." He leaned in closer, pressing their hips together before sliding his hand up to cup Marcus' growing erection through his sweats. "So how about it?" he asked teasingly, rubbing the length of Marcus' cock as he held it firmly in his palm. "Do you want your daddy to fuck your ass and fill you full of his love tonight?"

"Fine," Marcus sighed finally, rolling his eyes. It wasn't like he had much of a choice in the matter anyway; resisting his father never worked out well for him. He stood up and began to pull off his sweatpants and underwear, revealing his smooth, muscular ass to Leon. "Just...hurry up," he muttered as his father released his cock with a wet pop.
Leon grinned and gave his son's cock one last tug before letting it slip free of his grasp. He leaned over to grab some lube from a nearby table and then positioned himself behind Marcus. His erection was already pressing against his son's ass cheeks as he greased up two fingers and slowly pushed them inside, testing the tightness and readiness of Marcus' hole. Once satisfied with the slippery warmth that enveloped his fingers, he slowly began to thrust them in and out, fucking his own hand while watching the sight of his cock sliding between Marcus' cheeks.
"You ready for me?" he asked roughly, already knowing the answer as he pulled his hand free and positioned his hard cock at Marcus' tight entrance. There was no waiting; no asking twice. With a swift thrust, Leon buried himself to the hilt in his son, filling him completely with heat and pleasure.
"God...you feel so good," he groaned, beginning to move slowly at first before picking up speed as their bodies synchronized together. His hands found purchase on either side of Marcus' waist, holding him still while he took what he wanted from his son's ass. With each thrust, more of his seed was deposited inside Marcus' insides, flowing through his veins and binding them closer than ever before.

"Ahh..." Marcus moaned softly as he felt the fullness of his father's cock stretching him. He couldn't help but arch his back and grind down against Leon's hips, needing more contact between their bodies. "Fuck...Daddy," he panted, unable to focus on anything except the pleasure coursing through him as they moved together like they had a thousand times before.
Leon gritted his teeth and closed his eyes, feeling every inch of himself being devoured by his son's ass. He leaned forward to rest his forehead against the back of Marcus' neck as he began to pick up speed, their bodies slapping together with each forceful thrust. He could feel the tension building inside him, and with a groan he pulled almost all the way out before slamming back in with enough force that it caused both of them to gasp.
"Gonna cum...so fucking close..." he grunted through clenched teeth, holding onto his son's hips as best he could while trying to maintain control. The feel of Marcus' ass enveloping him like a velvet glove on his cock only served to heighten the pleasure and bring him closer to the edge. He arched his back, pressing deeper into his son with each thrust now, unable to hold back any longer as he erupted inside Marcus' body with a low growl of ecstasy.

As Leon groaned out his release and filled him up with seed, Marcus arched his back even further and let out a shaky moan, gripping the couch cushions beneath him as he felt himself spurt across the living room floor. His father's hands squeezed at his sides as he kept moving in short, sharp thrusts, making sure every last drop of cum was emptied into his son's body before finally collapsing against Marcus' back with a satisfied grunt.
Leon lay panting against his son's back, their combined weight making the couch creak beneath them. His cock twitched as he pulled out, leaking a few more drops of cum onto the floor before he finally slipped free with a wet pop. He slumped back onto the couch, still cupping his son's hip with one hand while idly rubbing the small of his back with the other. "That felt good," he murmured into Marcus' ear, nipping at his lobe gently before letting out a satisfied sigh. "I love you, kid." It was a mantra; a phrase he knew would not be questioned or challenged. And it was true: he loved Marcus more than anything else in the world. Even though they shared something unusual and perhaps even taboo, there was no denying that their bond was deep and unbreakable.

"Yeah," Marcus muttered tiredly. He knew he should say something else, but his father's words had the same effect every time. They made him feel...a little less weird about it all. "I love you too." Despite the distance between them sometimes, there was no denying that they were connected in a way most people could never understand. And for better or worse, they were each other's entire worlds.
Leon smiled at the back of his son's head before leaning forward and planting a kiss there. "Good," he murmured, wrapping an arm around Marcus' waist and pulling him closer. For now, they had each other. And that was all either of them would ever need. They could face whatever came their way as long as they had this bond to hold onto; this strange but special connection that defined who they were and what they meant to each other.

Marcus snuggled up to his father, letting out a sigh. He couldn't deny that it felt good to be near the man. "You know... sometimes you're a bit... a big jerk," he said, shrugging.
"I try my best to be," Leon replied with a laugh. "But you know I'd never actually do anything mean to hurt you." He squeezed his son a little tighter and nuzzled into the crook of his neck, inhaling deeply of Marcus' unique scent. "And besides," he added playfully, giving him a sharp love tap on the hip with his free hand, "you kinda bring it out in me sometimes."

Marcus rolled his eyes and tried to squirm away from the love tap, but his father was too strong for him. "Well... maybe you should work on your personality a little bit more." He paused, thinking about it for a moment. "Or lesson?" he suggested helpfully before relaxing against Leon again.
"I'll keep that in mind," Leo chuckled, giving his son another playful squeeze before letting him go. "But you know, there's something to be said for the way we are. It's our own special thing...that makes us who we are." He looked down at Marcus thoughtfully. "And besides," he added with a grin, "it's not all bad being me, right?"

"Yeah..." Marcus said softly. "But you could at least be a little less of an idiot... at least with me..." he said, resting his head on his father's shoulder.
Leon chuckled softly and tousled Marcus' hair gently. "I try my best," he assured his son with a shrug. Even though they shared an unconventional relationship, there were still things that Leo wanted to keep private and separate from it; their personalities included. "But you know I love you anyway," he added, giving Marcus' side a squeeze before lying back on the couch again, taking in his son's presence with contentment.
"So...want to watch some TV or something?" Leo asked conversationally, already knowing the answer would probably be no. But it was nice to pretend sometimes that they were just a normal father and son enjoying each other's company on a lazy evening in front of the tube.

"No..." Marcus said, closing his eyes, before snuggling even closer to his father. "...I want to go to bed and sleep..." he said, before yawning softly.
Leon smiled fondly at his son's yawn and gave him a gentle kiss on the top of his head before letting out a quiet laugh. "All right then," he murmured, rising to his feet with Marcus still nestled against him. "I can respect that." He carried Marcus over to the bedroom, gently laying him down on the bed before pulling off his own clothes and sliding in beside him, wrapping his strong arms around the boy's waist once more. As he closed his eyes, Leon couldn't help but feel a sense of contentment wash over him; despite all their ups and downs, having Marcus there with him made everything seem alright.
