Karin stood in the door way between two hotel rooms. The buxom high school graduate, stood naked and looked into the adjoining room. She had been in bed with her school friend Kevin's father. Her parent's had just announced their open relationship, in the sexual revolution of the 70's. Now as she peered into the next room, her Mother Lacy got double teamed by Kevin and his father, John. Her mom and John had conspired to reserve rooms together and Lacy was getting all the action at the moment.
"Mommmm" she cried for the third time now; her surprise faded now since, she had just been fucking John too. Why wouldn't her mom want his dick as well? John's cock had some nice thickness, Lacy found. She sucked on his son Kevin's dick, which was only slightly thinner. Karin decided, she needed to get in on this. She knelt next to Kevin and began to play with his balls. His moan punctuated her success. Karin got down on her hands and sucked his balls into her mouth. She sucked and swirled them like big gumballs. Her mom turned over on the bed and got on her hands and knees. She took Kevin's dick back in her mouth and used her hands to work the shaft. She licked up and down the underside of Kevin's reddening poker. His fire built up and the veins on his dick bulged out as she pumped up the pressure. Lacy took Kevin's dad doggie style from the other side of the bed now. He poked and prodded her pussy while, she remained preoccupied sucking off John's son.
Kevin could not hold back very long with a mom and daughter team working over his dick. The head went from red to purple. Kevin's precome began to leak into Lacy's mouth. Then she offered Kevin's dick to her daughter. Karin did not hesitate. She sucked down her long time school friend like a Nevada Whorehouse pro. Staying in Reno had them in a mood for a good time. Karin worked Kevin's cock against her cheeks on both sides. She sucked gently and licked delicately around the circumcised head. Kevin fired his first shot into the family friend's teen lips. Karin licked her chops and swallowed as much dick as she could take in and took all the continuing ejaculations down her gullet. The fresh teen partner sent Kevin's responses into the point of no return before he could take a breath. Karin milked out his sperm and enjoyed the teen taste.
John continued fucking her mom while, mom played with Kevin's erupting balls. Kevin stood up and walked around the bed and started fingering Lacy's clit while his dad drilled her deep. Lacy came hard on the slow touch. John kept sliding in and out like a ramrod in an old cannon. John's dick rubbed Lacy, on the ridges of her vagina. This rougher tissue could start a fire. It only needed a little dick friction. John was just the man for the job, right now. His foreskin tickled her nerves in the most maddening way when he changed directions. He flipped her back on her back again and put her knees over his shoulders. Her open belly invited Kevin to join his father and play with her tits. Lacy moaned as the youth kneaded her milk bags. Using her moans as his guide, Kevin got her whole body hot, as his dad kept up the dick drilling. Then Kevin stuck his face right down on her pussy and licked her clit as his dad fucked her.
This was too much for Lacy. Her puss contracted spasmodically on John's loaded sperm injector. The hydraulic multiplication on his large shaft blew the pressure release on his sperm duct. John howled and Kevin laughed knowing he accomplished his intended goal. "John," Lacy murmured. "You have got to try that on your wife with Kevin too! I never felt such an overwhelming stimulation like that!"
"I want to try that too, Mom!", Karin chimed in. "That did look awfully exciting to me." The two men looked at the fresh teen and caught their breath. No words were said. Such an offer is never refused. The father and son went to the shower and the mom and daughter went to the next room. Lacy brought out her lady's shaving kit and lathered up her pubic hair. Then she showed off her handy work to Karin and gave her the shave kit. Karin thought it looked really hot. Her bikini was thinner than her mom's and shaving would help keep any bush hair from showing so easily all the time. Karin's teen slit looked very inviting, with no interfering follicles.
By now, the father and son family friends stood at the middle door between the rooms. Kevin's cock sprung up as soon as he saw Lacy's bald pussy and it started pulsing and throbbing when he saw Karin's smooth look too. He wanted to feel them both and stepped into the room. Lacy had a stance that put her on display like a store window. Kevin cupped and slid his fingers across her pussy and walked up to her daughter and started kissing her on the lips. His hands traced her whole body from her mouth to her belly button. So slowly he continued further south in an unobstructed fingering of his friend. Her ball sucking earlier had been catalytic to his detonating testicles. Kevin wanted to return the favor and he tickled her lightly all around her vulva and mound. It felt exquisite. Karin gasped at the brink of an orgasm. Kevin sent her by pinching her clitoris gently between her labia. The indirect touch fired her tickle button like jump starting the boat at the lake.
Karin's responsive bare pussy got Kevin's father John on the case as well. John touched her and fingered her inside too. Karin gasped and her knees buckled. Father and son caught her fall and laid her on the bed. John wasted no time in poking his dick head up against bare slit and rubbing it around. His foreskin acted like a maddening tickler on her hyper sensitive pussy lips. He worked her up to another orgasm and the were not even fucking her yet. Then Karin's mom pushed John's ass and drove his cock right into her daughter. Kevin stuck his face in between her and his dad and commenced his cunnilingus. Karin's face glowed like coals on a barbecue. Kevin's clever tongue dug into her clitoral zone and urged out an slow string of building orgasmic waves.
Each crest of pleasure got better than the last one. Karin let go and didn't care what happened any more. She wanted to be fucked senseless if this was the way it could be. John had the experience to go for more than a few minutes. He slowed the pace and let his son's tongue do the work. Lacy enjoyed the show for now. Her little girl became a real woman, in front of her own eyes! Lacy cheered the men on and they did not disappoint. John shot juice on her daughter from her neck to her belly button. Kevin stepped up and slid in and they hardly missed a beat. Karin was delirious and cum drunk. "Fuck me! Fuck me some more! Fuck me all night. I never want to stop this!" Karin screamed out. The old brick hotel hosted yet another sex party in the old railroad stop party town.
The families had been close for years but the new open relationship thing brought an unexpected dimension to their friendship and vacation. A new chapter of lust and pleasure seemed to arise like Kevin's teen aged dick sprung up in the morning. All systems pointed in a positive direction.
