Summary: After their excitement in the woods, Cassie and Isaac try to sneak back into the house, only to be caught by their mother, Lori, who is both ashamed and aroused by their behavior.

Cassandra's heart raced as they reached the edge of the woods, with an open field between her and her little brother and their house.

As they knelt there, Isaac laughed. "This is crazy, sis! What if mom catches us?"

"Don't be a fraidy cat, little bro," she replied. "Doesn't mom go to the grocery store at this time on Saturdays?"

"Yeah, usually," he replied.

As Cassie knelt there, she felt a warm liquid slidiing down her leg and reached behind to wipe another glob of his cum from her asshole.

"Jeez, Isaac! How much did you cum in me?" She laughed.

"I finally got to cum in you, I couldn't help it."

"Well, come on, it's now or never." As Cass took off for the house at a trot, her little brother followed behind, staring appreciatively at the butt that he'd fucked less than 20 minutes before.

Lori heard the back door open and close. She had her head in the refrigerator, putting away the groceries. She hadn't needed much, so it was a short trip.

"Wipe your feet, kids," she said, not looking up as she set a gallon of milk in the fridge.

Cassie and Isaac stood frozen in place for a moment, unsure of what to do. Maybe they could slip by her without being seen? But the fridge was right by the entrance to the kitchen, and with the door open and her in the way, it was impossible.

"If you want, I can make some grilled chee--" Lori stood up and froze in the middle of her sentence when she saw her daughter's naked body. The plastic bottle of orange juice in her hand slipped as she lost her grip, and it fell to the floor, breaking the cap and causing the juice to splatter everywhere.

Just then, another glob of cum slipped out of Cassie's ass, and Lori saw it slide down her daughter's thigh.

"Oh! My! God!" she yelled.

"Mom, I can explain," Cassie started.

"Really? Can you? Because I'd like to hear how you talk your way out of this one," Lori yelled. "And is that..." she covered her mouth, unable to bring herself to ask whether it was Isaac's cum sliding down her leg. Eventually, she said. "Were you alone in the woods together? Or did somebody do this to you?"

Cassie and Isaac were speechless.

"The fuck, Cassie!" Lori barked. "He's just a baby!"

"I'm eleven," Isaac blurted out.

"Not helping," Cassie whispered out the side of her mouth.

"Get upstairs, both of you. Go into my bathroom and wash the...sperm from your pussy, for fuck sake and wait for me."

"Let us help you clean this up, Mom," Cassie offered, hoping that it would soften her mom, but no.

"Go! Now! Before I kill you both!" Lori barked.

Cassie shook her head in disgust and disbelief as her son and daughter....her incestuous son and daughter, went upstairs.

As they scurried past, she couldn't help but notice Isaac's cock, which was barely an inch long soft.

"God...is anyone in this family not obsessed with that cunt?" she thought to herself as she mopped up the spilled juice with a handful of paper towels.

She had no idea what she should do. Well, she knew that she should call the authorities. It would serve the bitch right, after all. But she was her daughter, and she knew that her son would probably never admit to doing it with her.

As she marched up to her bedroom and into the bathroom, she stopped when she saw the two of them standing there, waiting for her on the edge of the tub. Neither had covered themselves, but both looked appropriately guilty.

The differences in them were like night and day, but in a way they were the best of what they represented.

Isaac was small, and thin as a rail from playing soccer every chance he got. It had been years since she'd seen him nude, and it almost made her happy to see that he hadn't "grown" down there very much. To be honest, she'd always wished that he would never grow up, but apparently he had...at least in his mind.

Her daughter, on the other hand, was the epitome of gorgeous in every way. It hurt Lori to realize that even she admitted that. Cassie's large breasts showed no signs of sagging, and her pale, milky skin didn't have the first hint of a stretch mark. even her clamshell like cunt was just a narrow slit, unlike her mother's which her husband teased as looking like a roast beef sandwich.

"What the hell were you two thinking?" she said as she finally regained her thoughts.

"I'm sorry, Mom, It was my fault." Cassie said meekly, looking down.

"Well no shit, you are the adult!.

"No it wasn't, it was my idea, Mom, I dared her to do it," Isaac said, trying to take the blame.

"Be quiet, Isaac. it was my fault, I should take the blame."

"Shut up!" Lori yelled. Then she sank down onto the closed toilet lid, put her head in her hands and started crying.

Cassie and Isaac looked at each other for a moment, unsure of what to do. Then Isaac reached out a hand and put it on his mom's shoulder.

"It's okay, Mom," he said weakly.

Lori sniffled. Isaac put his hand under her chin and lifted her face up to him. She gasped when she felt his warm penis press against her bare knee. But when her son leaned in and kissed her, her whole world melted away for a moment.

"I love you, Mom. Please don't cry," he said, and then he kissed her again. She felt his cock stiffen against her leg, and she couldn't help herself; she kissed him back. She lifted her hands, wet with her tears and put them around his neck and held him there.

"We're so sorry, Mom," Cassie said, reaching out to touch her mother's hair.

Lori broke her kiss with her son and looked at both of them.

"It's not fair that I'm the one person in this house that gets the least sex," she pouted.

Cassie was taken aback. She'd never seen this side of her mother before. Sure, she could be petty sometimes, but Cassie never figured on it being jealousy.

"Well," Cassie said, taking her mother's hand. "We can change that for you."

Lori let her children lead her to her bed. She saw the picture on the nightstand of Cassie and her father. Lori was sure that her husband stared at that picture while he fucked her doggy style. She had to admit, Cassie's tits looked amazing in that bikini.

"Take off your clothes, Mom," Cassie whispered.

"No. I can't," Lori balked. But Isaac took her hand and brought it to his erect, little three inch cock. The feeling of his soft skin sliding over his hard shaft, and the warmth...and the thought that he'd gotten hard from kissing her...She melted.

Cassie saw her mother's reaction as Lori held Isaac's cock. She started unbuttoning her mother's blouse for her.

"I bet his little dick will get even harder when he sees your tits, Mom," Cassie suggested.

Lori felt dizzy. She was touching her son's dick. She was stroking him. He was hard in her hand, and...god help her, she loved it.

"Do you want to see my tits, Isaac?" she asked.

"Yeah," he said, with a big smile.

Lori reluctantly let go of her son's erection long enough to get her clothes off. Even though she'd had breast implants (at her husband's insistence) they weren't as full nor as perky as Cassie's. But the way Isaac's eyes got so big when they were revealed meant the world to her.

"Your tits look hot, Mom," he said.

Lori chuckled, her anger and shame slipping away.

"I think a comment like that deserves a blowjob, don't you think, Mom?" Cassie suggested.

She watched in amazement as her mother got on her knees before her brother. Lori looked up into her son's eyes and opened her mouth. She took him in without hesitating a moment. But when her tongue met his shaft, she was surprised by the taste.

Lori pulled away from Isaac for a moment in shock. She looked up at Cassie with wide eyes.

"You let him fuck you in the ass?" she asked.

Cassie shrugged and smiled. "He's got the perfect cock for it."

"Oh my god," Lori said.

She realized that her children were even more perverted than she'd originally thought. And then she realized that her pussy was getting really wet. Without another thought, she went back down on her son and started slowly sucking the flavor of her daughter's ass off of his little shaft.

Cassie had never realized that her mom was jealous of her. To be honest, she'd always thought her mother was so hot with the way that she spent so much time keeping herself up when so many other women were content to let themselves go.

Seeing her on her knees, sucking her son's cock instantly made Cass's pussy wet, especially knowing that she was tasting her daughter's ass while doing it. Cass had always considered herself a generous person, and knowing that their mother had been sex deprived gave her a determination to rectify the issue.

Moving behind her mother, she gently stroked her shoulders as she whispered in her ear. "Could you lean up for a moment, mom? I want to slide under you."

Lori was too lost in the blowjob to realize what her daughter meant, but leaned up slightly all the same.

She couldn't believe what she was doing. She couldn't believe that she was blowing her eleven year old son! But it was so rewarding, and she was wetter than she'd been in years! She knew it was wrong, but after being nothing more than a pussy for her husband to fuck while fantasizing about her daughter, she couldn't resist being the center of attention for a change.

Suddenly, she felt Cassie's hands on her thighs, and as she looked down she realized what her daughter had meant. Cass had slid on her back between her mother's legs and was looking up at her while gently rubbing the backs of her thighs and butt.

"Mmmmm, sit on my face, mom. I've never eaten pussy before, but I'd love for yours to be my first."

Lori considered herself to be 100% heterosexual, but the deviancy of what her daughter was asking made her heart flutter. Besides, she thought to herself. She'd already become an incestuous pedophile. Why not an incestuous dike too?

"Oh my god," she moaned as she ran her hands through Cassie's gorgeous blonde hair. "You're such a perfect whore."

She meant it with no malice, and as Cassie smiled, it was clear that she took no offence. She smiled as she watched her mother begin to blow her brother again while lowering her cunt onto her face.

As her mother's pussy came to a rest on Cassie's face, she breathed in deeply, smelling the aroma of her mother's soaking wet cunt. As she shoved her tongue into the messy folds of her twat, she savored the taste of her first cunt. Cassie had sucked enough cocks that had been inside of her to know what she tasted like, but her mother was different. It was a stronger taste, but good in a way. Her clit, too, was different, and stood out erect. She savored her mother's moans as she gently bit it before sucking and licking on it.

Standing above his mother and sister, Isaac was in heaven. He'd never seen anything so hot, and although it was his first blowjob, he knew his mother must be one of the best cock suckers on earth. He could tell that she was loving the oral sex she was receiving as well as she started grinding down harder on Cassie's face and moaning heavily on his cock.

"Ohhhh, Mom!" he moaned. "God, Mom, this feels so good! You're mouth feels so good, Mommy!"

Almost instinctively he started to hold her head and thrust. It was nothing for Lori to take the three-inch penis, and she happily began letting her young son fuck her mouth while she ground down on her daughter's face.

Isaac knew he was getting close, and his moans told his mother that he was too.

"Oh God, Mom! You're mouth feels better than Cassie's asshole! It's so warm and wet, and you're so beautiful!" he said as he looked down into her eyes. "I...I want to cum in your mouth, Mommy! Will you eat my cum if i do?"

Lori felt so dirty, so depraved as she nodded to her son. She wanted it. She knew she wanted it more than she'd ever wanted it from her husband or from any guy she'd ever been with. She wanted to taste her son's cum.

She felt Isaac's fingers dig into her hair. He was using her. Her husband used her but more like something to masturbate into. Her son was using her because he loved her. She could feel the love and the desire in him as he held her head and thrust into her mouth. She let him take over, happy to be a tool for his pleasure. And when he started whimpering "Mommy" over and over, she knew she was in heaven.

She almost forgot about Cassie underneath her until she felt her daughter nibble her clit again. It made her moan on her son's cock. She slid from side to side over Cassie's face, grinding herself against her daughter's mouth. She took ahold of Cassie's breasts, tugging on her nipples as Isaac fucked her face.

"Mommy! Oh fuck, Mommy! I love this. I love you! I'm gonna cum. Oh god, eat it, Mommy. Eat my...eat my CUUUUMMMM!!"

Lori felt her son's shaft thicken for just a second before he started shooting his jizz into her mouth. She felt wonderful as his pelvis slammed into her face. She let go of her daughter's tits to reach around him and grab her son's ass, holding him deep in her mouth as he sprayed her tongue with his load.

The sensation and the realization that she was taking her son's semen made her whole body tremble. As she swallowed down the first gulp of his seed, she felt her orgasm building. Then with one more lovely flick of her daughter's tongue across her clit, Lori started cumming.

Cassie tasted it, the juices flowing from her mother's vaginal hole, gushing onto her tongue, her lips, running down her cheeks. She lapped it up as fast as she could, desperate to drink her mother's cum.

Lori could barely hold on any longer, her body started shaking. She'd never been eaten like this before. Not only was it hot to be having her first threesome, but it was with her own children. And Cassie's mouth was very talented. Eventually, Lori fell over, sliding off of her daughter and collapsing in a heap on the floor.

"I think we broke her," Isaac joked.

"My babies," Lori moaned as her orgasm finished washing over her. "Oh my god, you two were amazing."

"Us? You sucked my ass juice off Isaac's cock and ate his cum," Cassie countered.

"Fuck, now I have to pee," Lori chuckled, putting her hands over her pussy and closing her legs.

"Will you pee on us, Mom?" Isaac asked.

Lori looked up at her son in wonder. Then she glanced over at her daughter.

"What?" Cassie shrugged. "So we did some watersports in the woods, too."

Lori laughed. She let her children help her up off the floor, and then she gestured for them to follow her back into the bathroom.

It was awkward, but with a common goal in mind, Cassie and Isaac laid head to head in the bathtub. Lori was thankful that her husband had opted for the jacuzzi option as it gave her plenty of room to stand above her children. Kneeling down so that she was hovering over them, she felt her body urge her to let go. She wanted to, but her mind kept stopping her, telling her it was too wrong.

Finally, though, she let go. It came out of her in a strong stream as she hovered first over Isaac's face, then moved to Cassie's. It felt so good to do something so humiliating, and she felt herself regaining the confidence that she'd lost. She reached forward, squeezing Cassie's beautiful tits as she urinated on her face and into her open mouth.

She couldn't believe what phenomenal children she had as they both openly swallowed her pee, debasing themselves for her pleasure. She was also glad that her workout routine required massive amounts of water, as it gave her a chance to pee on each for at least 20 seconds. She smiled, relieved and exultant, as she finished and stepped off of them, resting instead on the edge of the tub.

"I have to have the most amazing kids in the world!" she said breathlessly as she surveyed their wet faces. "I can't thank you enough."

Cassie and Isaac smiled as they leaned up and kissed each other, tasting their mother's pee on the other's tongue.

"No way, Mom," Cassie said with a loving smile. "I just wish we'd known that you felt this way before!"

"Yeah, Mom!" Isaac agreed. "I'm always horny, and I've just been wanting Cassie to return home so that I could finally fuck her! But I've been cumming in your panties all year! I can't wait to fuck all of your holes and eat your ass like I did with Cassie!"

Their support and love was overwhelming. Lori couldn't help but smile in love in return, and she grinned as well.

"For such a gorgeous woman your ass tastes terrible, Cass," she said with a laugh.

"Yeah, she's kind of right, sis." Isaac teased.

The End ... ?
