Lucy lay on the bed naked. Her 4 year old daughter Katie, also nude, lay atop her prone body, a breast in each small hand, with her wet pink lips sucking on one of Lucy's nipples. The horny mother's eyes were closed, and her hand drew soft circles on the warm skin of her daughter's back. She moaned when Katie's teeth grazed the hard nub of her nipple, and she put her hand on the back of the little girl's head, her finger's lacing through the soft blonde strands, and pressed Katie's face harder against her breast.

Lucy's hips rocked up and down to rub her wet pussy against Katie's knee, which was wedged between her mother's legs.

"Mmmmm," Lucy moaned, "Oh, Baby. You make Mommy feel so good." Katie lifted her head and smiled at her mother as she switched to the other nipple.

But as good as the sucking felt, Lucy's mind was wandering. She was thinking about the scene she had witnessed between her little girl and Katie's best friend, Suzie Lester. Suzie had visited one day, and after playing in the wading pool in the back yard - during which time Lucy had taken dozens of pictures of the wet, naked little girls - Lucy had observed a sexual encounter between the 2 four year olds.

At the time, she had passed it off as the normal curious exploration of children, but the more she thought about it, the less likely that seemed. The little preschoolers had been involved in some particularly adult activities. They had French kissed each other, fondled each other's pussies, engaged in oral sex; each had even put their tongues in the other's anus!

Where had they learned such behavior? And where had little Katie learned what she was doing right now: sucking on her mother's erect clit while slipping 2 fingers into her wet, shaved pussy? Lucy arched her back and thrust her hips forward against Katie's mouth. The little girl flicked her tongue across the hard bud of Lucy's clit, eliciting a long, throaty moan from her mother.

"Oh, Baby!" she gasped, returning her hand to the back of Katie's head to hold her close to her cunt, "Oh My God, Katie! Oh my God, Oh God!!!!!!!" she cried out as she came. Her hips bucked, and if she hadn't held her daughter's face against her crotch she would have bucked the little girl off.

When she collapsed on the bed, Lucy looked between her legs to see her pretty little blonde daughter grinning at her, her face smeared with her mother's pussy juice. Katie bent down and placed a long, wet kiss on her mother's clit.

"I love you, Mommy," the child said softly. Lucy could feel the little girl's warm breath on her wet, bald cunt.

"Oh, I love you too, baby girl," Lucy replied.

- - - - -

Lucy dropped Katie off at preschool later that morning and waited for Mal to emerge from the building after leaving Suzie. She saw him coming and smiled. He was a slim, handsome, young single father with thick dark hair and an easy, sexy smile. As usual, her heart beat faster when she saw him, but this time it was from nervousness.

"Mal," she said, stepping over to the attractive man as he moved toward his car.

"Hey, Lucy!" he said, grinning. Lucy's heart skipped a beat when she saw that sexy smile, but pushed ahead with her prepared remarks. She hesitated when she saw his eyes traveling up and down her body, taking in the sight of the denim mini skirt and tight pink tank top she wore. She began to wish she had worn a bra when her nipples hardened under his appreciative stare.

"Can we talk?" she said, keeping her tone light and her smile friendly, "At my house?" The look on Malcolm's face changed from a look of concern at her initial question to one of pleased eagerness at her second remark.

"Oh, uh, sure!" he said, grinning eagerly, "No problem!"

- - - - -

After getting him coffee, Lucy sat across from Mal in the living room. She stared at her cup, watching the steam rise and swirl while she organized her thoughts.

"You know when Suzie came over last week?" she began.

'Yes," Malcolm replied.

"Well, the girls were playing in the pool..."

"Yeah, you showed me pictures," Mal offered.

"Right," Lucy agreed, "But not all the pictures." She looked up at him and stood.

"Come on," she said, heading to the study, "I'll just show you."

Lucy retrieved the hidden thumb drive while Mal entered the small room. She sat on the wheeled chair and pulled up the photos, enlarging them one at a time as she spoke.

"The girls had a great time posing," she said "In fact, they really seemed to like showing off their bodies."

As she clicked through the photos, they grew more and more risqué, until the girls were spreading their legs wide to show off their plump, hairless mounds and spreading open their labia to expose the darker pink interiors of their vaginas.

"I see," Malcolm said softly. Lucy turned and looked up at him. His eyes were glued to the screen as he looked at the pictures of the naked girls.

"There's more," Lucy said.

"More pictures?" he asked.

"No" she corrected, "After they were done, the girls went to Katie's room to get dressed."

"OK..." Malcolm said carefully.

"When I went to check on them," Lucy continued, "They were - um...."

"Were what?" he prompted.

"They were kissing," Lucy said, "And touching each other. Not like kids would do, experimenting, but like adults."

"Really?" Malcolm said. He sounded nervous, but not alarmed, "What were they doing?"

Lucy described the sex show she had witnessed, leaving out no details. When she finished, her nipples were erect again, and she felt a pleasant tingle between her legs, behind her damp thong. Malcolm was not unaffected either. Lucy glanced down and noticed a pronounced bulge in his tight fitting jeans.

"I have a question," he said. She looked up at him, her pony tail keeping her hair from her face and making her look more like a teenager than the mother of a 4 year old.

"I'm not judging, just asking," he continued, "Why didn't you stop them?"

The question hung thickly in the air between them. Lucy stared at him, unable to answer, though the answer was obvious.

Because it had turned her on to watch! She had masturbated at the door to Katie's room as her daughter ate her friend to an orgasm! Lucy's cheeks flushed with embarrassment and lust at the memory.

"OK," Mal said, when Lucy couldn't answer. "Can I show you something?" He reached into his pocket and retrieved his cell phone. He tapped the screen a few times and brought up a photo album.

Mal crouched next to Lucy's chair and held his phone so she could see the screen.

Lucy gasped when she saw the first image. Malcolm's daughter Lucy sat on her bed, naked. She was leaning back with her hands behind her, holding herself up. Her legs were spread out in front of her with bent knees, offering a clear view of her bald pussy. Lucy was familiar with the view, but was somehow pleased that she wasn't the only one to have taken such pictures.

Other photos followed the first, showing the little 4 year old brunette holding her legs up straight, peeling her labia apart, kneeling with her butt pointed to the camera, and spreading her ass cheeks to provide a clear view of her tiny pink rosebud. Lucy was sweating by the time Mal got to the tenth picture.

It was Suzie's room but a different view. Suzie knelt on the bed, and she wasn't alone. Katie was there, too!

Both girls were naked, kneeling side by side, smiling at the camera. There followed a series of pictures similar to the ones Lucy had taken of the girls displaying their charms in the pool, but there was a difference. In some of Mal's pictures, the girls were kissing and touching each other.

Lucy's breathing grew ragged as she saw photo after photo of her beautiful 4 year old daughter French kissing her little friend, touching her body, playing with her nipples and squeezing her butt. She looked up at him inquiringly.

"I would never hurt Suzie," he said huskily "Or Katie."

She knew then. Without asking or Malcolm telling her outright, she knew that he had had sex with her little girl. That's where she had learned how to kiss like that, and how to eat Suzie's pussy. Had Malcolm taken her virginity? It seemed likely. Katie's hymen had been gone before Lucy had penetrated her with her finger, so it was possible.

Her vision blurred, going black at the edges. She saw Mal move to crouch in front of her, staring into her dark blue eyes.

"I would never hurt Katie," he repeated. Lucy's eyes welled with tears, spilling over to run down her cheeks in hot streams. Malcolm looked at her nervously, until she threw her slim arms around his neck and buried her face in his shoulder. Her felt her tears soaking through his shirt. She started shuddering, and he assumed she was sobbing.

Mal was surprised when Lucy pulled back and he saw that she was laughing! She continued to laugh and gasp until she was able to speak.

"Oh, it's too funny!" she said, chuckling as she spoke, "You've been doing it with my daughter.....and so have I!" She collapsed forward against his chest, giggling and panting.

"Really?" he asked, caressing her back to calm her down.

In answer, she lifted her flushed face to his and kissed him. He held still as she tipped her head to the side and opened her mouth, sliding her wet tongue over his upper lip until he parted his lips.

The kiss grew frenzied. Lucy reached between his legs to fumble his pants open as he pulled at the bottom of her shirt.

They had to stand to get undressed. Lucy pushed Mal's pants down and yanked at his dark blue briefs. His hard cock sprang up in front of him when she released it from its tight confines, and she took the 7 inch length in her hand.

She had to let go briefly when Malcolm lifted her shirt off over her head. She dropped to her knees in front of him and took the thick rod back in her fist before engulfing the fat head between her lips. He moaned and held her head gently as she sucked his cock and played with his balls.

He collapsed back into his chair and Lucy followed, her lips around his hard cock. She took his cock from her mouth and licked the length of his shaft, slipping lower to suck his balls into her mouth one at a time.

"You're gonna make me cum too soon," Mal panted.

She smiled up at him and rubbed the head of his cock on her lips, chin and cheeks.

"You wanna come upstairs and fuck me, Baby?" she purred. Malcolm's deep groan was all the answer she needed. She stood and helped him up. He pulled his shoes and pants off, and Lucy took his hand and led him upstairs. His hand slipped up under her miniskirt to squeeze her ass cheek, exposed by her thong, and she giggled.

- - - - -

They fell on the bed with their arms around each other and their lips together. Mal rolled onto his back, pulling Lucy on top of him. His hands found her ass, squeezing and kneading the firm warm flesh as they kissed, their tongues wrestling wildly. Lucy gripped his head in both hands and pressed her wet lips hard against his, pressing her tongue deep into his mouth.

Mal pulled Lucy's thong down her ass onto her thighs and dug his fingers between her butt cheeks to tease her wet slit with his index finger. She moaned encouragingly against his tongue as he fingered her tight pussy.

She reached down and gripped his shirt, pulling it up over his head and off. He took her in his arms and rolled over to lie on top of her. Raising himself on his elbows, he looked into her eyes, then bent forward to kiss her chest, between her breasts. She took his head in her arms when he sucked her nipple between his lips and teased it with his tongue. Her eyes closed when he moved to the other breast, then kissed her on her belly, moving lower.

She opened her thighs to give him access to her shaved pussy, and he dove in, digging his tongue into the warm folds of her inner labia. Lucy hissed and arched her back as Mal ate her. She was so horny from the pictures and the conversation, she came almost at once, squeezing his head between her soft thighs.

Mal moved back, holding himself over her body on his arms. He took his cock in his hand and guided it to her wet cunt, sliding the head up and down against her slick opening. He bent forward to kiss her as he slid his cock inside, pressing his lips to hers as she gasped. His tongue carried the taste of her own sex to her mouth, and she sucked it eagerly as he started a steady rhythm, sliding his hard shaft in and out of her tight pussy.

He and Suzie had had a late start that morning, so he hadn't made love to his daughter as he usually did. He was horny, and ready to cum, and it didn't take long for Lucy to hear his breathing change in the familiar manner that told her he was about to explode.

"Oh, are you gonna cum for me, Baby?" she panted into his ear. He felt her hot breath on his neck and nodded, moaning.

"Mmmm, yeah," she said, "Cum for me, Baby. Cum in my hot pussy!"

Malcolm's pace picked up as his orgasm approached. He groaned loudly and held still, and Lucy felt the head of his cock expand, and the stream of sperm that shot from his cock.

"Oooo!" she squealed. He resumed pumping as his cock drooled semen into Lucy's pussy, until his body relaxed and he fell atop her sweating body, panting.

"Mmmm," Lucy cooed in his ear, "That's my big boy." She kissed his cheek and neck, and he turned to return her kiss.

"Wow," he said, "That was awesome." Malcolm rolled off her and looked at her naked body. Her denim skirt was bunched around her waist, but she was otherwise naked. He let his fingers trail across her body, teasing her nipples and stroking her leaking pussy.

Smiling, he scooped up some of his semen on his fingertip and raised it to Lucy's lips. She took his finger in her mouth and sucked it clean.

They made out for a few minutes, until Mal noticed the time on the bedside clock.

"We need to go get the girls," he said. Lucy whined and cuddled against him.

"Wanna do lunch?" she asked, looking up at him with a sexy smile, "And....whatever?" He stared down at her.

"With the girls?" he asked.

"Of course with the girls, Silly." she said, "We can't very well leave them at home."

"You know what I mean," he said, smiling knowingly. Her return smile was lascivious.

"You never know," she said slyly.

"Are you horny again already?" he teased. In answer she pushed him on his back and leaned over him, kissing him with her mouth wide and her tongue deep in his mouth. She kissed him wildly for a minute, pulling away with his lower lip between her teeth.

"Yup," she smiled after releasing his lip. He felt her hot breath on his face and grinned.

"Wow,' he breathed.

- - - - -

"Yay!" the girls squealed when their parents told them they were going out to lunch. They went to Katie and Suzie's favorite fast food restaurant, and Lucy and Mal sat together at a small table while the girls played in the little indoor play area attached to the restaurant.

Katie wore a pink miniskirt and a blue t-shirt with Sleeping Beauty on the front. When she slid down the slide, her skirt rode up to show off her Mulan panties. Lucy had picked up the underwear recently, and had purposely gotten them 2 sizes too small, so they were molded to the little girl's fat pussy lips in a sexy camel toe.

Mal stared appreciatively as she reached the bottom of the slide and paused with her legs spread. Lucy noticed, and called the little 4 year old over.

"Show Mr. Lester your new underpants, Sweetie," Lucy told her daughter. Katie looked at her mommy for a second, then smiled and turned to Suzie's daddy and picked up her short skirt.

"See?" she said happily. The small panties were stretched tightly just below the child's narrow hips, hanging low on her belly. The front of the underwear was wedged between the child's legs. Her labia bulged out on the right side.

"Wow," Mal said, "Those are amazing!" He stared at the girl's crotch, enchanted.

"Hey," said Suzie, running up to the trio, "What about my panties?" The jealous little girl lifted her skirt to show off a pair of pink panties with hearts on them. Since her father had picked them for her, they were far too small as well, and practically disappeared between her puffy pussy lips.

"Yours are very pretty, too, Suzie," Katie's mommy assured her.

Mal was still staring at Katie when Lucy spoke into his ear, "I think we should move this party to your place. We're drawing attention," Mal looked over his shoulder and noticed a few people - mostly men - looking at the girls holding their skirts up. He smiled at Lucy.

"Right! Ready to go, girls?"

- - - - -

Lucy had no idea how to proceed. She was horny as hell at the prospect of a sexual encounter with Mal, Katie and Suzie, but was nervous about how to go about it without alarming the girls.

She needn't have worried. The girls were so excited they could hardly contain themselves. But Katie and Suzie were nervous, too. Suzie and Katie both knew that Suzie and her daddy had sex. Katie had joined them a few times. Both girls also knew that Katie and her mommy had started having sex. But as far as the 4 year olds knew, neither of their parents knew about each other.

And keeping the secret was killing the little girls.

"Girls," Lucy said. She was sitting on the couch next to Mal, and the girls were trying hard to stand still and listen, which was difficult because they had been behaving themselves all morning at preschool and they were excited and horny after flashing their panties at Suzie's daddy earlier.

"We have something to tell you," Katie's mother continued, "I've been talking to Suzie's daddy, and it turns out that we have something in common." Lucy paused, unsure how to continue. She decided to go with "Show and Tell".

Lucy leaned forward and took Kate's shoulders in her hands and moved her daughter closer. She pressed her lips to Katie's mouth and kept them there, until Katie got the idea and opened her mouth to accept her Mommy's tongue.

Suzie stared for a minute, then looked at her father, who was smiling. The pretty little brunette grinned and jumped into her daddy's arms. Mal scooped his beloved child into his lap and kissed her.

The 2 couples made out next to each other for a few minutes, then Lucy pulled away, gasping.

"Let's get you out of these clothes, shall we?" she asked her pretty blonde daughter. Katie clapped and smiled, holding her arms up so her mommy could pull her shirt off over her head. Her short skirt soon followed, leaving her in her small panties.

"Me, too!" Suzie cried, clambering off her daddy's lap to join her friend, stripping off her clothes as she moved.

Soon the 2 little girls were naked, and Katie moved in front of her mother.

"Wanna trade?" Mal asked, and Katie grinned expectantly at Lucy. Lucy looked at Suzie, whose thick dark hair fell in waves on either side of her pale, heart-shaped face. Her dark brown eyes were big and wet, with thick dark eyebrows above. Lucy felt her nipples harden as she looked at the beautiful little girl's pale pink nipples. They were hard, but almost invisible against the creamy skin of her chest and belly. Lucy looked uncertainly at her daughter, unsure of how Katie would react if she had sex with this pretty little dark haired angel.

"It's OK, Mommy," Katie assured her, "I can share you for a little while," She sounded so mature that Lucy had to smile.

"OK, Baby," she said, turning to Suzie, "How about a kiss, Sweetheart?" she asked. Suzie climbed into Lucy's lap and put her arms around her neck, raising her face to her best friend's mother. Lucy smelled strawberry shampoo as she bent forward to put her lips gently on Suzie's. The experienced little 4 year old opened her mouth and slid her tongue along Lucy's lower lip. Lucy moaned and extended her own tongue, tasting her second little girl tongue ever. They French kissed for a few minutes while Lucy ran her warm hands over the little girl's soft young body. Suzie sat on one of Lucy's thighs, grinding her bald pussy against the woman's bare leg, as Lucy gripped her butt cheeks in her hands, squeezing and kneading the firm flesh of the 4 year old's ass. Suzie moaned softly when Lucy's middle finger probed gently at her tiny pink anus. The little girl put her pink lips against Lucy's ear.

"I like it in my asshole," she said softly, in her high pitch, little girl voice. Lucy moaned and rubbed the wrinkled hole harder, pushing the tip of her finger into the tight opening. Suzie sighed and lifted her hips to give her best friend's mommy easier access to her favorite hole, giggling when Lucy pushed more of the slender digit into her ass.

Lucy looked over Suzie's shoulder to see Katie standing on the floor between Malcolm's knees. Mal was naked, and Katie had his hard cock in her mouth, gripping the base with her small fist and pushing her head down to take as much of the man's cock in her mouth as she could. Lucy looked at Mal, who glanced over and smiled languidly.

"Not wasting any time, I see?" she said, smiling ironically.

"Well," he said, "this isn't our first time, you know."

Watching her little baby girl sucking on a grown man's cock was a huge turn on, and Lucy needed to get out of her clothes so she could fuck Mal's daughter in front of him. She gently moved Suzie over and slipped out of her skirt, pushing her bright pink thong off with them. She pulled her tight fitting tank top over her head, leaving herself naked.

Lucy knelt on the floor and Suzie grinned, leaning back into the sofa cushions and spreading her thin legs in anticipation. Lucy put a hand on each of the girl's upper thighs and pushed them back and apart, so she could see Suzie's puffy white pussy and her crinkled pink anus. She leaned forward, smiling into the little girl's big brown eyes, until her lips met Suzie's pussy mound. Lucy's eyes sagged closed as her tongue parted the folds of Suzie's pussy and slipped inside. She smiled when she heard the child moan happily. The horny mother buried her face in the child's pussy, sucking the juices that leaked around her tongue.

Suzie humped against Lucy's face, pressing her pussy harder against the woman's lips and bumping her tiny clit on Lucy's nose. When she moved her hips up, Lucy's tongue slid over her anus, until Suzie kept her crotch raised with her asshole pressed insistently against Lucy's tongue.

Taking the hint, Lucy cupped the child's ass cheeks in her hands and pressed her pointed tongue against the wrinkled ring of Suzie's anus. Suzie whined and panted as Lucy sucked her asshole, rubbing her clit with a sharp little finger. Lucy held on tight as the child's body bucked and shuddered through an orgasm. She looked up at Suzie's sweaty, flushed face and saw a weak smile. Suzie's lips stood out red against her pale face, and the tip of her pink tongue peaked through the gap where a front tooth was missing.

Lucy glanced to her left to see Katie bouncing on Mal's seven inch cock. Her little pussy was stretched around the shaft, most of which disappeared repeatedly into the child's vagina. From her position on the floor, Lucy could see between her 4 year old daughter's ass cheeks, where her pink asshole winked at her from between the twin globes of her ass.

Lucy moved between Malcolm's legs and teased her daughter's anus gently with her finger. Katie turned to look at her mommy over her shoulder and smiled, leaning forward against Mr. Lester to give Lucy a better view. Lucy moved the digit to the intersection of Katie's pussy and Malcolm's cock, scooping up the combined sex juices from his shaft and returning to press her slick fingertip against Katie's asshole.

While Lucy fingered her daughter's ass, Suzie clambered off the couch and slid under the woman's pussy, lying on her back and gazing at the wet slit above her. Lucy felt the child's small tongue probing her hole, and settled over Suzie's face with a groan. She leaned forward and lapped at Katie's anus while moving her finger gently in and out of the tight, wrinkled orifice.

Katie lay on Mr. Lester's chest, panting and moaning while the man fucked her pussy and her mommy licked her asshole.

"Oh, Mommy!" she panted, "Oh, Mr. Lester! Oh, Mommy, oh, oh oh!" she cried as she came. Lucy rammed her tongue into her daughter's asshole when she heard the sounds of the 4 year old's orgasm, holding onto her slim hips as the little girl shuddered through her climax.

Lucy moved her tongue to Malcolm's cock as it pistoned in and out of her little girl's pussy, tasting Katie's juices on the slick shaft. He moaned when she moved her lips to his balls, sucking in one testicle, then the other.

"Ahhhhh, I'm gonna cum!" he groaned, and Lucy pulled her daughter from his cock with her hands on Katie's waist and engulfed the spurting head of Malcolm's cock between her lips. She felt Mal's cock spurting and his daughter's tongue lapping at her clit, and shook through her own powerful orgasm. She gripped Mal's strong thighs and rocked her hips, rubbing her drooling pussy against Suzie's face, leaving the little girl's features slimy with her cum.

She lifted her head from between Malcolm's thighs and smiled up at him and Katie, her lips pursed.

"Mommy!" Katie scolded, "You ate all the cum!" the little girl scowled with a sexy pout, and Lucy rose to her knees to kiss her daughter. Katie accepted the kiss reluctantly, but her big blue eyes flew open in delight when her mother opened her lips to let Malcolm's semen leak from her mouth into Katie's. The little girl moaned against her mother's tongue and swallowed the warm load happily, grinning at her mommy with semen smeared teeth.

"Thank you, Mommy!" she said, wrapping her thin arms around Lucy's neck in a big hug.

Suzie scrambled onto the couch and leaned against her father, planting her slimy lips against Mal's. He tasted Lucy's pussy on his daughter's mouth and squeezed her firm ass as they kissed.

- - - - -

On the drive home, Katie asked the question Lucy had been expecting - and dreading.

"Mommy, when can I fuck Daddy?"

"Oh, Baby," Lucy replied, "I'm not sure. You have to give me some time to work on that, OK?"

"'kay," Katie said from the back seat.

"But you can't tell Daddy about ANY of this, right?" she admonished.

"Yes, Mommy," Katie replied. She rolled her eyes. Adults always told her not to tell when they had sex with her, and she never did. At least, not by name.

Lucy considered the situation. She had been anticipating Katie asking about having sex with David since she and Katie had started. She didn't know how he would react, or even how to broach the subject with him, though watching Katie sucking on Malcolm's cock had given her an idea. She spent the rest of the drive home considering details.

Yes, this could work.....
