Family Christmas

"Oh!" Their mother said.

A sense of relief came over Emma and Steve.

"I also saw them the other night in Emma's room. On my way back from the toilet I heard them. Emma's door wasn't closed properly and I watched."

"You both kept the same secret from each other. Mum's known about us for a long time, she has this annoying habit of finding us in bed together." Emma laughed nervously.

"From now on we should be more open with each other." Their father said.

"All right. I have a confession. Your son touched my backside this morning and I enjoyed it." Said Maureen.

"Emma says you enjoyed my finger tips going between your bum cheeks." Steve smiled at his mother.

"I especially liked your fingers going between my bum cheeks. I was doing my best not to smile and encourage you. I enjoyed seeing your erection as well."

"From what I've seen it is impressive but is it as big as mine?" His father took his own penis out and massaged it to erection.

Steve was very happy with the compliments from his parents but felt embarrassed at seeing his father standing and playing with himself and his face began to feel hot.

"And Emma, you have a very beautiful body and you are very, very sexy." Her father said.

Emma stared at her father's penis and blushed just like her brother.

"Steve felt mum's and my bottom at the same time." Said Emma.

"So Steve who has the better bottom?" His father asked.

"I only felt mum's through her night-dress and Emma was naked so it wasn't an equal comparison." Replied Steve.

"Steve you must conduct a proper test. Ladies! Skirts up, panties down." Dave said to his wife and daughter.

Emma looked at her mother for encouragement and watched her unzip her skirt and pull down her panties revealing a neatly trimmed narrow strip of dark brown pubic hair. Standing Emma removed her jeans and panties revealing her clean shaven pussy.

"Emma you have a beautiful cunt." Her father said while still playing with himself.

Hearing her father use the word cunt shocked Emma and made her very excited.

"Steve was naked as well, and he had an erection." Their mother added.

"Take your clothes off Steve and get yourself an erection." Their father said.

Steve removed all of his clothes and Emma smiled because he did not need to play with his penis like his father to make it erect. Steve's mother stared at his erect phallus. Dave moved closer to his son and they compared sizes only to discover that they were identical in size and shape.

"Dad, I think we should both perform this test on their backsides?" Said Steve.

"Good idea son. You start with your sister and I'll start with your mum."

Emma bent forward over the table and offered her backside to her brother. Putting both hands on it Steve felt its smooth round shape and as he had done before he slipped the tips of his fingers between her bum cheeks. Their father did the same to their mother, smoothing both hands over her backside and then slipping his fingers between her bum cheeks. Both Emma and Steve watched breathlessly as their mother moved her feet apart and their father moved forward and pushed his penis between her legs.

"That feels nice." Their father said.

They watched as their father fucked their mother and copying them Steve guided his penis between his sister's legs and fucked her.

"Steve, let's swap places now." His father said.

Their father pulled his penis out of his wife and Steve took his penis out of his sister, but before he moved away Steve knelt, kissed Emma's backside and licked her pussy. His father saw him and did the same to is wife.

Standing in front of her son Maureen offered him her backside. Steve touched it and slipped his fingers between her bum cheeks while his father did the same to Emma. His mother felt Steve's penis on her backside and moving her feet apart he slipped his penis between her legs. His mother was very wet and Steve's penis slipped easily between her pussy lips.

Emma's heart beat fast as her father put his hands on her backside. His hands felt rougher than Steve's and she enjoyed the feel of his fingers between her bum cheeks. Almost immediately her father pushed his penis inside her.

Kneeling Steve kissed his mother's backside and stretching out his tongue licked her pussy and Emma waited for her father to do the same to her.

"Let's all go up to our bedroom. We'll be more comfortable there." Said Maureen.

Maureen lead the way followed by Emma and Steve while Dave turned out the lights.

"Is the bed big enough for all of us?" Asked Emma.

Maureen smiled.

"It's plenty big enough for the four of us."

"You sure?"

"We've had four people on here many times."

Emma lay back on the bed with her mother kissing her on the lips, not the kiss that she usually got from her mother but wet lover's kisses. Moving down to her daughter's breasts Maureen sucked hard on her nipples while Steve moved behind his mother and easing his penis between her legs he pushed it deep into her pussy.

Their father came into the room and went straight over to Emma's legs which she moved apart allowing him to put his penis inside her. Steve came first shooting his cum deep inside his mother. He moved over to Emma and kissed her on the lips and with all the attention she was getting Emma came next moaning loudly.

Emma and Steve sat together and watched their parents fuck. They were turned on and began to fuck each other. The four of them sat together on the bed when they had finished and Steve leant over and put his hands between his mother's thighs, lifting her knees she parted her legs and he ran his fingers across her pussy lips.

"You're sticky."

"Your cum and your father's cum caused that."

Emma parted her legs and everyone put their hands towards her pussy. Steve got their first.

"You're sticky as well."

"Same reason as mum." Emma said.

"I enjoyed that. I'm going to wash." Emma kissed everyone and got off the bed.

"I'll join you." Her mother said.

When they were alone, Steve and his father sat against the headboard.

"Sleeping arrangements tonight." Steve's father said.

"What!"

"If you stay in here with mum tonight I'll go in with Emma."

"I like that idea."

Emma and Maureen liked the sleeping arrangements and before Emma and her father left the bedroom for Emma's room Steve asked.

"Dad. Have you ever done anything with your sister?"

"Yes. He's fucked her on a number of occasions." Said Maureen.

"Is that why you never got angry with Emma and me?" Steve put his arm around his mother's shoulder.

Maureen felt relaxed and at ease and sucked her son's penis.

"Maybe it is and maybe I had another reason." She replied.
