Marcus is a teenage boy who just got home from school. He lives with my father, Leon, a 6'3" tall, 40-year-old man with a muscular physique, black hair, and green eyes. He has a condition that causes him to ejaculate a lot. They live in a two-story house, and each has their own room. Leon fantasizes about filling his son's ass with his semen, over and over again, until his son's abdomen is swollen with it. The older man is always looking for an opportunity to fuck Marcus's ass, to ejaculate inside and fill his own son. Leon only jokes about it until he finds the chance to fulfill his fantasy. He proudly talks to everyone about his perverse fantasies, saying that a father should fuck his son as much as he wants, that he will fulfill them, and that he will be the only man in Marcus's life to fill his ass with semen. Leon didn't give a damn about the world's opinion or the taboo surrounding incest.
Leon nodded his head affirmatively as he took another sip of beer, feeling the cool liquid slide down his throat. "You know what they say, Marcus? A father should fuck his son until he's raw and swollen." He winked at him, chuckling darkly.
Marcus could feel himself blush as he tried not to look too uncomfortable. His dad had been talking about this stuff more and more lately...and it was starting to scare him just a little bit.
"Dad..." Marcus sighed, rubbing the back of his neck. "You know that's not really...healthy." He hated having this conversation with him. It always made things feel so weird between them.
Leon threw his head back and let out a laugh that seemed to echo through the house. "Oh, come on, son!" he said, waving a hand dismissively. "It's just sex! It's natural! Besides," he added with a mischievous glint in his eye, "if I don't fill your ass with my seed, who will?" He paused meaningfully before leaning in closer to Marcus. "I need to make sure no other man ever touches you...mark my words."
Marcus moved slightly away from his father, avoiding his gaze. "Dad... I already told you those jokes weren't funny..." he said uncomfortably.
Leon snorted. "Jokes? They're not jokes, son! That's the way it should be between father and son!" He reached out, roughly gripping Marcus' arm. "You're mine, you understand that? I made you, and I have a right to take what's mine." There was a dangerous glint in his eye as he stared at Marcus.
Marcus's body tensed slightly, and fear gripped him. "Dad... please don't..." he said weakly, already knowing this wouldn't end well.
Leon leaned even closer, his voice lowering to a dangerous growl. "Oh, I will, son," he said darkly. "I'll make sure you know who your daddy is...and that no one else ever touches what's mine." He let go of Marcus' arm with a harsh shove, sending him stumbling backwards onto the couch.
Before Marcus could even react, Leon was on top of him; his strong hands roughly pinning down the younger man's arms above his head on either side of the back of the couch. "Don't fight it," he snarled. "This is what you want...what I need." His breath hot against Marcus' neck, sending shivers down his spine.
"Dad, please!" Marcus said quickly, feeling fear grip him as tears streamed down his face. "Dad..." he tried to plead, to stop the man, but he knew it was no use. "...please...don't be rough...I promise I won't resist..." he said weakly through his tears. He knew he couldn't stop him, but at least he could try to find a way to avoid being brutally raped. "Please...I'm sorry for what I said..." he sobbed. "...I-I'm sorry...please, Daddy..." The tears wouldn't stop, and the fear intensified. "...p-please...be gentle..." he gasped, his breath ragged through his tears. "...D-Daddy..." he called out to his father one last time, pleading like a small child, his eyes still closed, sobbing. He hoped that deep down, his father still felt some mercy for his own son.
Leon growled low in his throat, clearly unable to resist his own desires for much longer. But he couldn't help but feel a small sense of satisfaction knowing that Marcus was begging him. He leaned forward, pressing his hips against the younger man's ass, grinding himself against Marcus' opening. "I am your father," he whispered harshly before spitting into the warm pucker of flesh. "And you are mine." With one hard thrust, he pushed himself inside Marcus, eliciting a choked sob from his son as their hips connected with a wet and tight heat. "FUCK!" Leon cried out, burying himself deeper, feeling every inch of his length disappear into the hot, welcoming channel. "Oh fuck..." he moaned, starting to pump his hips roughly against Marcus' ass, claiming what was rightfully his as his son's cries filled the room. "Daddy..." Marcus gasped through tears and snot. "...please...make it fast..." He didn't want this...didn't want to feel like this...but there was nothing he could do. His father had him trapped, helpless and at his mercy. And now that the first initial pain was subsiding, a strange and unwanted sense of pleasure began to creep up on him as their bodies moved together. "...please..." he begged softly, arching his hips into each thrust. "Fuck me...Daddy..." He didn't know why he was asking for this...for more...but he couldn't help himself. As the feelings built inside him, Marcus felt a strange mix of shame and arousal wash over him. His father's rough hands gripped his hips, holding him in place as Leon fucked him harder and faster,
