20-year-old Jean cut the lights off on the car as she turned the corner leading to her home. She was two hours late again and if her parents caught her she would be grounded and her car keys taken away for a week.
A bit old to be treated like a child but she was still in college, that they were paying for, and her parents held her nose to the grindstone with the adage, "you live under our roof, you do as we say".
She exited the car and immediately headed towards the back of the house, hoping her brother Billy had opened the back door as he had promised.
Rounding the corner of the house, Jean sensed a presence and stopped to take a look around. She heard a light moaning and followed it halfway down the back of the house to her parents bedroom windows. She saw bare feet under the bushes near her parent's right window and a distinct heavy breathing and moaning. As she had occupied the same space occasionally, and had recently clued in her 19-year-old brother, she knew it could only him.
"Billy! What the hell are you doing?" She whispered.
"Go away!" She heard him whispered back.
The hell I will, she thought, and eased her way through the bushes being careful not to break any limbs. She found her brother stroking his firm erection and peeking through the vertical blinds of the window. His actions did not surprise her. But her parent's action of leaving the blinds halfway open, did. Of course, one had to be inside the high, thick bushes to see in the window.
"Give me some room so I can see too!" She whispered, elbowing her brother.
Sister and brother were spying on their parents, John 51, and, Betty 43.
The still quite attractive Betty was on her knees with her chest on the bed and her ass postured up high. It was her favorite position but she never let on. She always voiced displeasure when asked to assume this position, but a wise woman had her secrets to keep her man interested.
John was pumping into his prize acquisition with a moderate rhythm, his money having swayed her decision to marry him instead of his best friend. The friendship had not survived
.
It took Jean a second or two to focus through the blind.
"Don't you just love to watch dad fuck mom?" Jean asked her brother.
"I would say, I love to watch mom fuck dad." Billy revised.
Jean soon had her hand up under her short skirt, her fingers under her panties fingering her pussy. She soon joined her brother with her own heavy breathing and moaning.
"How long have they been at it?" She questioned.
"Dad is big on foreplay. The usual kissing, touching. They fucked missionary a while. He ate her pussy about 8 or 10 minutes ago. Her orgasm was strong. Now he's working on getting his." Billy answered. "About 45 or 50 minutes."
"Dad must be tired tonight. Or, he'll pull out and fuck her in some other position. Looks like he going for the gold, though, doesn't it?"
As they watched, John was ratcheting up his rhythm with each minute that past. Soon he was pumping with determination sending his cock deep into Betty's pussy. Betty's face was soon pressed into the pillows in an effort to stifle her moans. They thought their children were fast asleep in their rooms.
"He's close. Look at him go!" Jean said with elation, brought on by her masturbation but mostly from her desire to have her father fucking her instead of her mother. "I love to watch him come!"
Billy glanced at his sister inquisitively, hearing the lust in her tone.
"Let's go out to the pool house." He suggested.
"I want to see him come first!" She retorted.
"Okay. But stop fingering yourself save that for me!" He offered, already having ceased his own masturbation.
"Okay! Okay! But leave me alone for a minute! I want to see this.
John was now pounding against Betty's ass. He was indeed close and he was concentrating on his wife's moaning.
Jean saw her father push deep, the anguish on his face telling her that his cock was jerking inside her mother's pussy, filling her with his cum.
Jean reached to take her brother's hand, dragging him with her through the bushes. Hand-in-hand they ran for the pool house.
Inside the pool house, brother and sister began to strip each other.
Billy felt very fortunate to be removing the clothes of the short-haired, freckled face, redhead that was his sister. At 5'7", 118lbs, ultra-slim and long legged, with a bubbled ass, a firm body from swimming and running, and old-fashioned enough that she retained a strikingly lavish red bush between her legs, she was a force to be reckoned with.
Jean, six months earlier, had seduced her brother to quench her thirst for sex and further her desire to seduce her father. She had recently decided on a a course of action..
Sister and brother fell into a pile of life-preservers and lounge chair padded seats and backs.
Billy's hands were roaming all over his sister's body. Jean tried to maneuver him into position to couple, but he was moving up and down her body, kissing and fondling her. When his head went between her legs she gave up.
"Damn it Billy! All you want to do is eat my pussy. I have been fucking Carl tonight! I cleaned up but not that good. I want to fuckkkkkkkkk!"
The orgasm hit her mid-word and her ass shot skyward.
In an instant, her brother was on top of her and poking at her pussy to enter her. He found her hole and stabbed his 6" thick cock into her muscle tight pussy, taking her breath. She did not lash out at him for being so rough. Instead her legs tightened around him as her ass matched his frenzied rhythm.
"Yes! Fuck me!" She encouraged. "Fuck me daddy! Fuck your daughter's pussy!"
Billy had heard the incestuous banner before and paid it no mind as he sought to fill his sister's pussy with his cum.
Jean was excellent at reading a partner's sexual nuances and knew after watching their parents fuck her brother would not last long.
"Give it to me! Give it up Billy!" She chanted. "Screw your sister's pussy! Come in me daddy!"
"GGGggrrrrrrrrrrrr!" Billy groaned as his cock jerked.
As usual, Billy's youth allowed him to continue fucking his sister, until she was satisfied.
Eventually, they lay side-by-side, Jean positioned with her legs wide as her brother fingered her pussy spreading the semen over her vagina and lush mound. They were unconcerned that they might soil the life-preservers or cushions.
"You know you are a pervert." Jean stated more than questioned. "Would you like to be doing that to mom's pussy?"
"You know I would." Billy replied.
"You're getting me hot again." Jean said lustfully. "Put your finger on my clit. Yes! Don't move it! I mean it! Don't you fuckin' move!"
