A phone was ringing in a damp, sweaty bedroom, a man with natural, golden brown skin and greying dark hair picked it up. He was sweating profusely and lying down on his back, on a bed.
"Hello," the man said breathlessly.
"Yo dad, it's me, Kevin. Dad, I turned 18!"
"That's great son umm, ohh yeah, so your mother and sisters broke you in?"
"Yeah Dad, it was awesome."
"Glad to hear it Son, I'm coming over soon, ohhh yeah, I'll be there soon."
"Dad, you sound kinda weird, are you in the middle of something?"
"Well Son, you could say I am in something."
While speaking to his son, the father -- Joseph Karlson - was being rode on by his gorgeous Chinese wife Cynthia. She was gently swivelling her hips as she got ready to climax. Her long dark hair draped down her face, her hands planted firmly in her man's chest; in that sweltering bedroom, they were both naked.
Joseph pinched her butt, so his son can hear her voice; she let out a high-pitched, "yee," Kevin was really excited to meet her.
***
The Karlson's were a family that promoted 'free love', that meant that they would have sex with each other and with anyone else they desired, at any time. Making up the family were Joseph and his ex-wife Denise, and their children. Oldest was daughter Kelly, in the middle was other daughter Shelly and the newest one made aware of the family's secret was youngest son Kevin.
Joseph Karlson divorced his wife because he fell in love with another, Cynthia. Unlike his previous wife Denise, Cynthia was unaware of the 'free love' concept, and Joseph was very willing to break her in.
To make the deal that much sweeter for Joseph, Cynthia had a son. Joseph could not wait to expose, exploit and fuck Cynthia in front of her son. Cynthia's son was named Charles.
And so it began. Joseph met Cynthia when she was working as a hotel receptionist, he began dating her and before long, it turned into a serious engagement. That's when he started playing mind-games with her son, Charles.
He started of slow at first, just touching her ass in front of him and playfully kissing her. He slowly progressed to making comments about Charles's mother in front of him, comments such as, "You're a very lucky lad for having such a gorgeous mother."
Charles just chalked it up to Joseph being Joseph. Gradually Joseph's personality changed Cynthia; she wore more sexy clothing like short-shorts and tank-tops. This change made Charles notice, in more ways then one.
As more people noticed Cynthia, her son had to endure dirty comments about his mom from his friends. Deep down, what confused Charles more was the fact that he liked those dirty comments. Joseph went as far as showing Charles the lingerie he had brought for Cynthia.
From there on, it was full-speed ahead for Joseph. Cynthia listened to every word he said, she even allowed him to have sex with her in the shower. Joseph timed this rendezvous so that Cynthia's son would be awake just when they finished up. Charles saw both of them walk out of the shower after having sex. Charles could not deny it, that incident was a turn-on for him.
Then came the deal closer, Joseph left the door open and let Charles watch him having sex with Cynthia. He even went a lil rough on her in the bedroom because he knew her son was watching. Joseph was 6'2 and Cynthia was 5'6, so he was able to use her in various positions at his willing.
As time went on, it all became more of a show for Charles. Joseph made his wife parade around in a thong on the beach and finger fucked her for good measure.
Joseph went so far as to actually post his and Cynthia's honeymoon video online, which Charles has watched over and over. He set up the website so that Charles could be the only one who could watch that video.
All of Joseph's objectives were done, he had made Charles lust after his mother and made Cynthia his willing sex slave. The final phase of Joseph's plan was about to commence, it was time for Joseph's families to meet.

On the car ride over, Cynthia and Joseph were in the front and Charles was in the back. Cynthia was in her usual beige shorts and white tank-top combo, while Joseph and Charles wore regular jeans and t-shirts. Charles was eager to see his step-sisters, who he had met before at the wedding. On the car ride over, he asked about them.
"So Joseph, is Shelly and Kelly gonna be there?"
"Umm not Shelly but Kelly, I think, I'm not sure... What's wrong? Looking forward to seeing your step-sisters?" he chuckled.
"Oh no, no, no," Charles said defensively, "just asking is all."
"Oh come on now, they are just your step-sisters. You can say there hot."
"Umm ok," Charles was weirded out by that comment; they are Joseph's daughters after all. For the duration of the car ride, Cynthia stayed silent.

Over at the Karlson family home, it was morning. Kevin, son of Joseph, was awake and getting ready for his morning shower. Kevin had spiky, black hair and a well toned, tan body.
After being alerted to the family's secret, Kevin was allowed access to the family shower room. Unlike a normal bathroom, the shower room was a room which was entirely a shower, similar to the communal showers in gyms, but this one was much larger in scope.
He put his towel on and walked into the decoy bathroom; the entrance to the family shower room was hidden inside the tiny shower cubicle. He walked into the cubicle and pushed the wall gently as it revealed a hidden passage.
He walked the well-lit passage and admired the roman-style mural paintings that decorated the walls. After a short walk, he found the family crest on a sliver door and walked on in.
As soon as he opened the door, he felt a rush of water sprinkle down on him. The large room had a marble-encrusted floor and lavish decorations around the room. Kevin took off his towel and found his eldest sister Kelly in the corner.
Her curvy, sensual body soaking wet, her hair in a neat wet bunch, her tan sexy skin shimmering under the water and lights. Kevin went over and made a large smack sound when he slapped his sister's ample wet ass.
He nudged his chin on her shoulder and said, "Hey yo, you know Dad's coming over today?"
"Urgh," she said discouragingly, "he's coming over with that chop-socky bitch."
"Oh come on now Sis, don't be like that, she's got to be a hot piece of ass." He rubbed her inner thigh with his free hand; he was trying to get his sister going.
"Oh dear sister~, ready for some morning delight?" He rubbed his cock against her ass and slowly cupped one of her wet breasts.
