James and Juliet McAfey sat in their comfortable chairs enjoying the tranquility.
"Isn't this just so wonderful James. Julie and Jimmy aren't fighting any more. No more shrieking and yelling and screaming between our children. At last they're starting to act like 18 year olds," said Juliet
"Sure is," replied her husband. "I don't know what happened while we were away but they've changed from hating each other to spending all their free time together."
"Yes and Julie's being so nice. Why tonight she told me that she was going to help Jimmy with his French."
James felt a glow of pleasure at Julie's generosity to her twin sibling, then thought for a moment. "That's odd, Julie's never been to a French class in her life."
At that very moment, upstairs in Jimmy's bedroom their children were acting like 18 year olds in a way their parents hadn't imagined. Julie was instructing her twin brother in the only French tuition that he needed: how to get his mammoth manhood balls deep into her ass.
"Come on Jimmy, ram me, wham me, Roger me, split me. Just get that monster cock right up your slut sister's slut ass."
Jimmy, her twin brother was completely undeveloped for an 18 year old. Match stick arms, a concave and hairless chest and stork like legs. But he had the one attribute that was the focus of his sister's frantic attentions: a cock the size of a giant cucumber. As Julie lay on her back with her legs pulled wide and high he pounded his male pile-driver deep into her beckoning anus.
"Aaaaaah, Uuuuuugh, Eeeeeeeeh, Ooooooooohhhhh" Julie shrieked with her rectum convulsing in an orgasm around her brother's monumental masculinity as it plunged deep into the inner black recesses of her gaping bowel.
Then with her body still trembling from her excitement and glistening with perspiration from her efforts Julie lay on her back and opened her mouth wide. Jimmy knelt beside his sister's head and proceeded to ream out her throat, banging his prodigious penis full length into her cruelly stretched maw.
Later, still panting Julie looked at her scrawny brother with affection. "God Jimmy, your cum is the best I've swallowed. Can I have a repeat course soon, very soon, straight away?"
Jimmy gently slapped her nose with the still enormous knob of his flaccid cock. "Sorry slut sis, but Suzie is coming around to give me some instruction in the 10 Commandments."
Julie screwed her face in mock disappointment but in her heart she knew that her mouth and cunt and ass needed some respite from her brother's outrageous organ.
The sounds of their daughter's anal orgasm filtered down the stairs to the living room where her parents listened. Neither was an expert in the French language although they had spent two days in Paris on their 10 day whistle stop tour of Europe.
"That doesn't sound much like the Frenchmen I heard on the Eiffel Tower," said James.
However he was interrupted from his contemplations by a knock on the door which he opened to let in Suzie, the pastor's cute daughter.
"Hi Suzie, have you come to help Jimmy with the 10 Commandments again?"
The pastor's cute daughter smiled innocently. James thought she looked so sweet and demure with her hair tied in long braids and her dress which covered her from her neck to her wrists and ankles.
But James became aware of other thoughts than Suzie's innocence. Her long dress couldn't disguise the jutting shape of her breasts, her narrow waist and her firm, rounded ass. He was getting the same thoughts as he sometimes got when he stood beside her singing in the choir in her father's chapel.
"Temptations of the Devil!" he cursed himself and wondered whether he too needed some more instruction in the 10 Commandments.
"Hi Mr and Mrs McAfey," Suzie smiled cutely. "Wasn't chapel choir practice so uplifting yesterday?"
"Such a cute girl and so devout," said Juliet as she watched Suzie walk up the stairs.
By the time the cute and devout Suzie had reached the top of the stairs she had undone her braids and her long blond hair hung down her back. By the time the cute and devout Suzie had reached Jimmy's bedroom she had taken off her all-covering dress and showed that she was wearing nothing underneath.
"Suzie you look so sexy," Julie gave a shriek of delight and rushed across the bedroom to hug her.
Suzie returned the hug and licked the remnants of Jimmy's cum from Julie's face as Julie's hand explored her body. Suzie parted her legs for Julie whose expert fingers soon found her clit.
"AaaaEeeeeeOooooooUuuuuuugh," groaned the cute chorister as she came.
Then Suzie explored Julie's cunt and and caressed her G Spot until Julie came to her umpteenth orgasm of that evening. Then Julie went to have a shower and left Suzie to her instruction on the 10 Commandments.
Suzie took this job very seriously but never got past the third Commandment.
"Thou shalt fuck my cunt," she said looking sternly at Jimmy as she lay on her back, her knees high and wide and her cunt open and glistening from Julie's touch.
Jimmy had fully recovered and needed no second command as he dived onto the pastor's daughter's cute and welcoming body. Suzie gave a little squeal of pain as his immense invader stretched her pink parts, then a far louder squeal of delight as her cunt relaxed to take him.
After she had cum Suzie knelt on the bed, her ass pointed high. "Thou shalt fuck my ass," she commanded sternly.
Again she went through three sensations: pain as Jimmy's monstrous masculinity split her anus, pleasure as her rectum walls were massaged and ecstasy as her ass and cunt and everything exploded in an orgasm.
On her knees she looked up sternly at Jimmy. "Thou shalt fuck my mouth and my tonsils and my throat."
Miraculously Suzie's oral organs somehow accommodated Jimmy's enormous extremity as it drove in and a few minutes later she had her second sampling of cum, this time in a bucket load.
While Suzie was being stretched and pounded and plundered Julie showered and then went to talk with her parents, sitting beside her mother.
