*****
As John awoke, he immediately heard them. Their walls were thin and his mind primed to absorb the humiliation.
"Yes, fuck your slut", she moaned. John imagined that he would stick his big cock into her willing pussy. Them James would grab her voluptuous tits and squeeze them.
"You love my big dick, Mommy, don't you?" Even through the wall he heard them kissing, wet sloppy sounds filling his mind and making his tiny dick harden.
John got of the little bed that James had allowed him to sleep in and silently went across the hallway. He poked his head though the bedroom door.
The bed rocked back and forth as James thrust his almost ten inches of thick fuckmeat into his wife's delicate pussy. After their fuck sessions she was always sore for a few hours, but there was no doubt she actually loved the rawness of her sons fucking. It reminded her so much of his father ... well, his real father.
James was not John's child. How could he be? John was starting to bald even at only 38 years old, chubby and had a dick so small it could barley fit into a woman.
When he met his wife Stacy, he could barely believe she wanted to be with him. He was below average even back then and Stacy was a bombshell of a woman. Medium height, golden hair and a body to kill for, complete with a big bust, a slim waist and the hips of a fertility goddess. He thought himself lucky and treated her as best as he could.
Shortly after he met Stacy, there was William. William was big black stud, the kind you see in porn all the time. He was 6'5'' with a dick almost a foot long and bulging muscles all over his body. At first John thought that Stacy and William were only friends. Until one evening he walked in on them fucking like wild animals. John tried to get William off his wife, but he just punched John on the shoulder. So he watched from the carpet, his shoulder either broken or at least disjointed.
After William had cum twice, once all over his wife's face and tits and then - just minutes later - inside of her, he left and was never seen or heard from again.
Nine months later she gave birth to James. There was no doubt about him being not from John. On one hand, John hadn't slept with his wife in over a year by this point. On the other hand, James looked nothing like his father, which became more and more clear as he grew up.
For starters, James was clearly the son of a black man and a white woman. His skin was dark and his features looked chiselled, although they had a certain softness to them.
When he was twelve James started working out. And it paid off, big time. Soon he had muscles covering all of his body, a thick back, impressive chest and a sixpack made of steel.
His penis, even as a boy an impressive 4 inches, grew longer and longer the moment he hit puberty. And it wouldn't stop. By the time he was 16, he was already eight inces - double the size of John.
On his 18th birthday Stacy measured the cock of her son. By this point, there was no reason to call it a penis anymore. At a strong eleven inches, the thickness of a female arm and blessed with the sexual prowess of a sex god, there was just one way to describe James' equipment: A big black cock.
That same day was when Stacy started fucking him. Or did he start to fuck her? John couldn't quite remember, but by dusk they were already on their second round. And they didn't stop until way past midnight when Stacy had had at least a dozen orgasms and James coated every part of her body with his semen.
Now, about a year later, John peeked through the bedroom door. James was sliding most of his big cock into his mother and grunted with every thrust. But his noises were completely drowned by the wails and moans of the woman before him. Only occasionally would he lean forward and kiss her shut her up for a moment, only to kiss his way down to her big tits...which caused her to moan even louder.
John looked transfixed at the two naked bodies gyrating against each other.
James noticed and turned his head. "Hi, Dad", he said casually, not for a single moment interrupting the pistoning motions of his dick. "You got breakfast ready?"
His father, John, shook his head slowly. Inside, he felt his stomach churn. He knew that James wanted him to be a good house-slave and tend to all his needs. After all, his mother was either fucking with him or too exhausted from the fucking to do almost anything.
"Good", said James and gave his mother three hard strokes, bottoming out with each one.
Did he mishear just now?
James saw the confusion on his dad's face and clarified: "I wouldn't have time for breakfast today anyway. Mom and I planned a few special things today and there is no time for eating scheduled in there."
He thrust deep into his mother and diddled her clit.
"Fuck, baby", she moaned and grabbed his strong arms.
"You can watch, if you want." James gestured for him to come in.
Without another word John got in, closed the door and sat on a small chair in the corner. Actually it was where his wife usually did her make-up, but lately it was his place. At least two times a day his son would fuck his darling wife, and at least once a day he would watch from this very place.
"Oh, fuck!", James' mother moaned. She looked over to where her husband sat, then turned to her beautiful son. "He looks like a creep, watching us." She kissed him, her tongue snaking all across is teeth, lips and gums. "I love it!"
"You know, dad, three things will happen today." James nibbled on one of his mothers nipples and licked all around her bossom, before he continued. "Mom and I have been talking. She wants another baby, or to be exact: We want another child. If it's be a boy, 18 years from now we will fuck her MILF body together."
"OH YES!", Stacy whined and bucked her hips wildly.
James grinned. "She is all for that, as you see. And if it's a girl, I will have not only a mother to fuck, but a sister as well. A ripe body and a firm young one to milk my cock all the fucking time." He shivered visibly at that thought.
His cock seemed to do something at this point as well, as Stacy rubbed her clit feverishly and came with a deafening cry of ecstasy.
"That is our first goal of the day: Fill mom up with as much spunk as possible, get her belly swollen and a little sibling by the end of the day. Secondly, I always wanted her to take it up the ass. But we currently have no lube at home..." He shrugged.
"But baby", his mother gasped from beneath him, "without lube I will never be able to fit your huge dick in my little asshole."
James grinned mischievously. "That is where you come into play, dad. You will get her shithole nice and ready for me. If you do a good job, I may let you watch her first time anal."
"But she already did it with me once, before you were born", John stated.
His son and wife looked at each other and laughed.
"Sorry, honey. You don't really think that compares ... like, at all, do you? He is over three times your size and you only had it in me a couple of seconds before you shot." She made a disgusted face, like always when she thought back to their few sexual encounters.
Then she caressed her son's cheek lovingly. "But my little - or should I say big baby will pound me for hours. You will, won't you baby?"
"I will, Mommy." James licked her lips, face and breasts. "I love all of you. And I will especially love your tight ass. I'm sure of it."
A few minutes of non-verbal fucking passed, then James spoke again. "And last but not least, I will fuck mom in public. Probably in a bathroom or on an empty lawn. You will keep an eye on the people nearby and distract them. If you have to, get naked and draw their attention. But I really want to fuck my Mommy in nature for once. That will be awesome. Sounds good?"
James didn't wait for an answer.
Steadying himself with one arm on the bed and with the other on one of Stacy's tits, he now really started the fucking. Like a mad man he rammed himself into her and grunted like a wild animal that had only had one thing in mind: Breed the female in front of him.
Unexpectedly, Stacy reached her hand out towards her husband and beckoned him to come closer. Timidly he did, as he didn't know how James would react to that.
She grabbed his hand and looked him in the eyes. "I want to hold your hand while James fucks his sibling into my womb. I want to see the look on your face when he does what you never could, and never should do." A small, sadistic grin crossed her face.
Seconds later, she screamed again, another orgasm washing over her.
James now pumped his big black cock into her pussy like a drill hammer. By the second he got faster, his lower region blurring at the speed. "FUCK! I will fuck you pussy everyday while you're pregnant. There won't be a day we don't do this, Mommy. Promise?"
His mom nodded, now moaning constantly. "Yes, baby. Every day, even the day I give birth to your son or daughter. And after I give birth, until we can fuck again, I will suck you off as much as you want."
James groaned. John wasn't sure if it was the thought of getting head as much as he wanted (even though that was already the case) or the thought of his mother carrying his child.
He was proven wrong immediately. "Mommy, fuck! The thought of my little baby bro or sis suckling your tits while you suckle on my cock is just so ... Ahhh ... so unbelievably hot!"
Stacy dug her nails into his wide back. "Yes, baby. I will eat your spunk while the little one drinks my milk."
James' last few thrusts almost looked comical, as he pulled almost all of his ten inches out and slid back in in no time. But what made it much less comical was the fact that they both moaned and cursed like filthy pornstars.
"Fuck, baby. Give me your cum. Fill me up, get me pregnant. Make your Mommy your personal breeding slut."
James hollered as he came. "Yes, Mommy! Take my fucking spunk!"
His ass muscles contracted again and again, accompanied by his guttural moans and her occasional high-pitched shrieks.
John thought they were done at one point, but he should have known better. Just then the cum leaked out of Stacy's pussy, and by the amount coming out James had to be still ejaculating.
