Sis

Slowly everyone got dressed. Dawn felt sore all over but also very, very happy. She felt more grown up, like a woman now, as she pulled her shirt on and stepped back into her skirt. Everyone kissed her goodbye and she and David went out to the car to go home.

“You were just unbelievable,” said David, putting an arm around her and holding her close as he drove off. “I’m so proud of you. Did you enjoy yourself?”

“Oh, yes,” gushed Dawn. “At first I was scared, then I didn’t know what I’d do if you or any of them stopped.”

“So you liked all of it?” asked David.

“Yes,” replied Dawn, “all of it.”

“You know, you can’t tell mom anything about any of this,” David said. “She’d kill both of us, but me the most.”

“Oh, I’d never tell her anything about it,” Dawn assured him. “But I want to do it again,” Dawn said, laughing. “I mean, I really liked it.”

“Well, as soon as Mom leaves for work in the morning, I’ll fuck you on the kitchen table,” David said with a grin as they pulled to a stop at their home.

“Yes, but where will you fuck me?” Dawn asked with a laugh. “I like it in my mouth and my pussy and my ass,” she said. “Can you do all of them?”

“You’ll see what I can do and what I can manage,” David replied.

When they walked into the house their mother was sitting there waiting for them.

“Well, I see you finally made it.” Sara said. “Did you enjoy yourselves?”

“It was great, Mom.” Dawn answered. “David’s really cool to take me with him like that.”

“Well, you’d better get to bed if you’re going to make it to school in the morning,” Sara said.

“Yeah, and I’m tired too,” Dawn said. “Good night, mom,” she said, bending over and kissing her mother on the cheek.

Sara noticed a peculiar odor as Dawn kissed her cheek, but she just shook her head, telling herself that it was just an over-active imagination on her part. After all, she had been with her brother the entire evening, so of course nothing like what she had thought of could have happened. Besides, it had been a while since she had smelled or tasted cum, so maybe she was mistaken.

For the next several days David and Dawn fucked and sucked each other at every possible opportunity. Whenever Sarah would leave the house, David’s cock would either be in his sister’s mouth, her pussy, or her ass. And Dawn just loved it. She was never happier than when either her face or her pussy or her ass was full of her brother’s cock.

Then came a time when Sara told them that she was going to have company that evening, that if they had something they could do with their friends, she would appreciate the space. Dawn was all excited at the thought of her mother having a date. David and Dawn left the house and went to visit Sue. But when they got there, Sue’s mother informed them that Sue had gone out for the evening.

Dawn then suggested that they sneak back to the house and go in the back door and go upstairs to her bedroom, which was the farthest away from Sara’s bedroom. That way, she said, they could fuck all night and not worry about it. When they got to their street, they saw a big pickup truck parked in front of their house, so they decided to park halfway down the block so that they wouldn’t be heard or seen as they came home.

Quietly sneaking in the back door, they carefully tip-toed through the kitchen to the hallway leading to their bedrooms. When they got to the hallway, they heard some soft voices coming from the living room. Dawn couldn’t resist taking a peek and she grabbed David by the hand and pulled him along, too, so that they could peek around the corner into the living room and see their mother.

What they saw completely shocked them. Sarah was on her hands and knees between her date’s legs as he lay on his back on the floor, his huge hard cock sticking straight up in the air where Sara was sucking on it. But what most struck David was the fact that his mother was naked and her ass and pussy were pointed directly at him. He was shocked to see that his mother’s pussy was smoothly shaved, not a hair to be seen. He could see her clit sticking out from between her pussy lips as she knelt on the ground, her ass up in the air as she sucked her date’s cock.

David could not believe how excited he became when he saw his mother’s pussy sticking out at him. He could make out moisture between her pussy lips and knew that she would be wet and sopping, just the way he liked it when he stuck his cock into a pussy.

Dawn had reached behind and grabbed his cock through his pants as she watched her mother sucking her date’s cock on the living room floor. She almost gasped out loud when she saw her mother lift her face from her date’s giant cock and move up to straddle him, reaching down between her legs and grasping his cock in her hand, holding it between her spread pussy lips and rubbing it back and forth.

They both held their breath as they watch their mother slowly lower herself onto her date’s giant cock, inch by inch seeing it disappear up into her pussy. By now David had flipped Dawn’s skirt up onto her back and was rubbing his own cock in her pussy from behind as they watched their mother fucking her date on the living room floor, her back to them and oblivious to their presence.

Quickly David pushed his cock into his sister’s well-fucked pussy, matching the stroke rhythm of his mother as she fucked her date on the floor. David’s excitement was never greater as he fucked his sister watching his mother fuck her date. When he heard his mother’s date moan out loud from the other room, David knew that he would shortly be cumming in his mother’s pussy. This further excited him and he increased his stroke rate, wanting to cum inside his sister’s pussy at the same time his mother got her pussy filled with cum.

When he saw his mother’s date’s feet stiffen and his mother throw her head back, David knew that he was cumming and it caused his own balls to explode, shooting yet another load of cum into his sister’s pussy while his mother’s pussy was also filled. When David finished cumming in his sister’s pussy, he let his cock slide out and helped her to stand up, smoothing her skirt down as she did. At the same time, they watched in frozen horror as their mother collapsed backwards so that she was looking right at them standing in the hallway staring at her. David thanked his lucky stars that he had already put his cock back in his pants by the time his mother saw them, and after a momentary frozen look between them, he grabbed Dawn by the hand and dragged her off down the hall before anything was said.

The next morning David and Dawn were eating breakfast when Sara came into the kitchen to join them. They were all silent until Sara sat down at the table with them.

“I’m very unhappy about what happened last night,” Sara said. “I had specifically asked for some personal space for the evening and I did not get it.”

“But, mom, we went out and couldn’t find any of my friends, and we didn’t know what to do, so we decided to come home and just go to our rooms,” David said. “We didn’t mean to spy on you.

They all ate their breakfasts in silence, and then Sara finished hers and had to go to work. As soon as she was out of the house, David pulled his cock from his pants and told Dawn that he wanted her to suck him, that he couldn’t get out of his mind the sight of their mother the night before.

With a laugh, Dawn eagerly dropped to her knees between his legs and began to suck his cock. David watched his cock disappearing into his sister’s mouth and wished that it was his mother instead. With thoughts like these in his mind and Dawn’s expert sucking, he quickly felt his balls begin to churn and then he was shooting hot cum into his sister’s mouth. When Dawn finished swallowing all of his cum, they both got to their feet and went to school.
