Chapter 13
Sirius was pregnant with their grandfather Arcturus's child. To legitimate the child had just married his young brother Regulus, who was only fourteen years old.
As the newlyweds entered their chamber, Sirius's swollen belly was a constant reminder of the taboo act that had led to this pregnancy. Regulus, still a boy, looked at his brother with a mixture of fear and curiosity. He had never been with a man before, let alone his own brother.
But Arcturus, the patriarch of the Black family, had other plans. He entered the chamber with a wicked smile on his face, ready to teach his grandson how to satisfy a man. Regulus, who had always looked up to his grandfather, felt a shiver run down his spine as he watched him approach.
"Tonight, my boy, you will learn how to fuck a slut," Arcturus said, his voice low and menacing. "And your brother will be your first lesson."
Regulus looked at Sirius, who nodded silently. He knew that this was the only way to legitimate the child and secure the Black family's future. With a deep breath, Regulus approached his brother and began to undress him.
As Sirius's clothes fell to the ground, Regulus couldn't help but stare at his brother's swollen body. Sirius, for his part, was nervous but excited. He knew that this was wrong, but he couldn't deny the thrill that ran through his body as Regulus touched him.
Arcturus watched from the sidelines, his eyes gleaming with excitement. He had always been a deviant, taking pleasure in the taboo and the forbidden. And now, he was going to teach his grandson how to do the same.
As Regulus's fingers brushed against Sirius's nipples, the older man groaned with pleasure. He had always been sensitive there, and Regulus's touch was sending waves of pleasure through his body. Regulus, encouraged by his brother's reaction, continued to explore Sirius's body.
He kissed Sirius's neck, nibbling gently on his earlobes. Sirius let out a soft moan as Regulus's lips found him, and their tongues intertwined in a passionate dance. Arcturus watched, his cock growing harder with every sound that escaped Sirius's lips.
As the kiss deepened, Regulus's hands began to wander. He cupped Sirius's ass, pulling him closer. Sirius wrapped his legs around Regulus's waist, grinding his hips against his brother's.
“Sometimes if you’re fucking someone they won’t be wet enough and you’ll need to use lube. Not for their sake, for your own. You don’t want to try fucking someone who’s completely dry, son.”
Arcturus watches the boy sink into that tight heat of his brother, his own hand on his back, guiding him.
“Good, son, good. Just like that. Now pull out a little and then slam back in. Don’t worry about being gentle. It’s an slut‘s purpose, taking cock. It’s what they were made for. Just fuck him at whatever pace you want. And if you want him to clench around you and he isn’t then pinch his nipples harshly or spank his arse hard. Yes, just like that. How does that feel, son?”
“Good. So fucking good.”
Arcturus chuckle over the boy’s enthusiasm.
“Good rhythm, Regulus, very good. You’re a natural at this. It won’t be long now before you will get your chance to impregnate him and then we’ll have lots of new Blacks running around, hm? You can fucked a baby into this little broodmare as soon as he births the one he’s carrying.”
“Fuck, oh fuck, father. Really?”
“Of course, grandson.
Arcturus watches as the boy’s thrusts begin to falter at that pronouncement and soon deposited his seeds in him
“Good, Regulus. You did very well for the first time.”
He turned Sirius around, bending him over the bed. Regulus watched as Arcturus positioned himself behind Sirius, his cock poised at the entrance to his ass.
Arcturus then turned to Sirius. "Open your legs, Sirius," he said. "I'm going to fuck you now."
Sirius obeyed, spreading his legs wide open. Arcturus positioned himself behind Sirius and slowly inserted his cock into his grandson's tight and wet hole.
Sirius moaned and groaned with pleasure as his grandfather's cock filled him up. He could feel every inch of it, sliding in and out of him with ease and grace.
Arcturus began to fuck Sirius with long and deep strokes, making him moan and groan even louder. Regulus watched as his grandfather's cock moved in and out of Sirius's hole, his own cock growing harder and bigger with each passing moment.
After a few minutes, Sirius couldn't take it anymore. He moaned and groaned as he reached his climax, his cock exploding with cum and pleasure.
Arcturus continued to fuck Sirius, even after he had cum. He was so happy that he knocked up his grandson with his own uncle
Finally, after a few more minutes, Arcturus reached his own climax. He moaned and groaned as he filled Sirius's hole with his own cum and pleasure.
