A few days later, thinking that they were completely alone in the house, Nikki and her big sister, Margo, met in the girl's bedroom for a pussy-sucking session.
The two sisters had been so busy making it with guys lately that they hadn't had much time alone, and they felt ravenously hungry for each other's pussy.
They were moaning and groaning in a tight, naked embrace, kissing with their tongues, just as Karen Andrews walked down the hall past Nikki's room. The girls' mother recognized the sounds of passion, and she felt a twinge of jealousy. It sounded as though her daughters were having so much fun. She longed to join them.
She pressed her ear against the bedroom door and heard Margo begin to squeal with the unmistakable sounds of orgasm. Inside the room, at that moment, Nikki was biting Margo's nipple as she stoked her older sister's clit with two juice-slickened fingers.
Karen waited until her daughter's squeal of pleasure subsided, then knocked lightly on the door.
Nikki and Margo hopped out of bed and struggled to put their clothes on again.
Before getting married, Karen had had a lesbian relationship with her own sister so the woman saw nothing wrong with what her daughters were doing. She knew how exciting it could be to make it with another girl.
The incestuous nature of her daughter's relationship did not bother their mother at all. It struck her as perfectly natural, and she just wanted to be a part of it.
"You don't have to worry, darlings. Don't get dressed. I'm not angry. Just open the door for your mom," Karen said, trying to make her voice soothing.
The two girls were surprised. They detected a knowing tone and a note of excitement in their mother's voice when they had expected anger and condemnation. They unlocked the door.
Karen had come home early unexpectedly from a shopping spree. She had been about to leave again to meet her brother, Frank, for one of their satisfying fucks. The second she had heard her older daughter's moans of orgasmic pleasure, the horny woman decided that she could have just as exciting a time right there in her own house. Thoughts of Frank faded.
She opened the door and entered Nikki's bedroom with a grin on her face.
"So… you two are lovers," she said, running her fingertips over her own nipples, which were poking against the tight blouse she wore.
"We… we didn't want you to know," Nikki stammered.
"But it's okay… really," Karen said reassuringly. "In fact, I like the idea… I think it's exciting."
Nikki and Margo exchanged glances.
"I was hoping you two girls would take pity on your horny mother and let me join in on the fun," Karen said with a warm smile.
"Sure, Mom," Nikki said. "I think we three could have a lot of fun together! But if Dad found out…"
"Don't worry about your dad. We'll keep this a secret. You're right, of course. He considers himself very liberal when it comes to sex, but if he found out that his own wife and daughters were getting it on, he'd be furious!" Karen said with a dramatic shiver which made her laugh.
Karen thought for a few seconds.
"Dad won't be home for hours yet. Let's go into the master bedroom where we can be much more comfortable in the king-sized bed there."
The two girls squealed with excitement. When they all got to the master bedroom, Karen removed her own clothes.
Completely naked, the three excited females climbed onto the oversized bed together. Karen kissed both of her daughters hungrily on their soft mouths.
Both Margo and Nikki moaned with shared desire, feeling their pussies drooling with lust. They all embraced, tongue-kissing each other for long, breathless moments. Nikki thought back to the night when she had spied on her parents fucking. She remembered how beautiful and sexy her mother had looked in the moonlight, her naked body all aglow.
At that moment, Nikki realized that, ever since that night, she had been hot for her mother. She had wanted to eat out the older woman's cunt. She had wanted to feel her own mother's mouth hungrily pressed against her cunt. But she had pushed those desires down, sure that they were wrong. It was one thing to make it with her sister but her own mother was another.
But, now, here was her mother, completely naked on her bed with her daughters, eagerly kissing and stroking both girls.
And if she sees nothing wrong with it, why should I? Nikki asked herself now. After all, she is my mother and she knows best!
The girl eagerly and unconditionally abandoned herself to her desires, throwing herself in the three-way fuck with her mother and her sister.
"Ohhhhh, I've got a great idea!" Margo cried as the threesome ended their long, torrid kiss. "Let's make Mom feel real good, Sis."
"Yeah, great idea, Margo!" Nikki said eagerly. "Just spread out on your back, Mom. Then let Margo and me do all the work. We'll make you feel real good!"
"Mmmmm, you're both such good girls," Karen said as she followed her daughter's instructions and lay on her back in the center of the big king-sized bed. "And I can tell by the way you both kiss that you both know how to make me feel really good."
The older woman stretched her legs wide apart for her daughters, who were already eyeing her hungrily.
Nikki licked her lips with anticipation, thinking that she would like to concentrate on her mother's big tits, for now. She placed her small hand beneath the older woman's left tit and lifted it up.
At the same time, Margo moved onto her belly with her head between her mother's splayed thighs.
Nikki began to kiss her mother's tits, harder and faster, her soft, wet lips moving ever closer to the taut nipple that seemed to throb before her eyes.
The girl parted her lips and stuck out her tongue, placing its pointed tip directly on her mother's nipple.
"Yessss," Karen sighed, closing her eyes in pleasure as her daughter rolled her tongue over her tit. The older woman began to pant and move her ass in a slow, seductive circle on the bed. Karen could tell that all of the pink cuntmeat between her widely parted legs was completely engorged with the hot blood of her incestuous lust. She felt more and more juice pouring out of her fuckhole, filling her pussy to overflowing and running down her thighs. Her clit arched and burned and throbbed, demanding release.
Nikki lashed her mother's tits with her tongue for long moments, her face moving quickly and hungrily from one tit to the other. She licked all over the quivering tit-mounds, until they were both completely coated with her, warm saliva. Then she concentrated on the twin nipples, stiff and rock hard. She whipped both of them with her tongue, relishing her mother's moans of pleasure. Finally, the girl wrapped her lips around one of her mother's nipples and began to suck.
"Ohhhh, yesss, that feels so good, Nikki! Suck your mother's tits hard, darling!" Karen groaned.
"Yeah, that looks hot! Suck Mom's tits hard, Sis!" Margo cried, all this time watching the exciting action from between her mother's legs where she inhaled the heady aroma of the older woman's fully aroused cunt.
Nikki moved to the other tit and she sucked that one hard, too, tonguing the pulsing nipple and grazing lightly with her sharp teeth.
"God, that looks hot!" Margo groaned, deciding that, as thrilling as it was to watch her sister sucking their mother's tits, it would be even more exciting to lick her mom's pussy.
The older girl stuck her tongue out and licked up and down the full length of her mother's cunt, tasting the delicious pussyjuice which rolled out onto her tongue. She hungrily drank it all down as she continued to lick the hot hairy cunt as hard as she could.
"Ummmm, ohhh, yesss, Margo, eat your mom's cunt. Make me come, you two darlings!" Karen cried, lifting her ass up from the bed and squirming all around in a fit of lust.
As her mother's ass lifted, Margo took the opportunity to lick the older woman's asshole hard. Then she returned her tongue to Karen's cunt, poking her tongue between the puffy folds of her cuntlips.
"Unnhh, eat me out, Margo, eat your mom's cunt!" the woman cried shrilly, delighting to the double excitement of one daughter eating her pussy while her other daughter sucked her tits.
She was touched by her girls' desire to give her so much pleasure. She had never felt closer to them than she did at that moment.
While Nikki continued to suck her mother's tits, moving rapidly from one to the other, Margo fucked the full length of her horny tongue up the woman's cunthole.
"Yeeeooowww! Yesss! Tonguefuck meee!" Karen wailed.
After tongue fucking her mother for a few minutes, Margo turned her attention to the rigidly quivering clit that seemed to be almost crying out to her. She licked the stiff bud hard and then she wrapped her lips around its base, sucking for all she was worth. Long clits seemed to run in the family.
At that exact same instant, Nikki sank her teeth painfully into one of her mother's nipples. The woman came.
"Commmiiinnnggg!" Karen shrieked, screaming with joy as gallons of orgasmic cuntjuice flowed out of her cunt and into her older daughter's sucking mouth.
"Mmmmmfffff," Margo moaned, her sounds of pleasure muffled by the wet cuntmeat that was spasming against her sucking mouth. And she came, too.
Still sucking her mother's tits, Nikki moved one hand down between her own legs and began to feverishly stroke her clit. She knew that both her mother and sister were coming. She had no desire to be left behind.
"Unnnhh, ahhh, oooohhh," Nikki cried, releasing her mother's tit with a wet popping sound as she came too.
The three orgasming females clutched at each other, grabbing tits, squeezing running pussies, as their naked bodies writhed violently on the bed.
Still coming, Karen suddenly knelt between Nikki's legs and attacked her daughter's cunt with her entire mouth, using her tongue, lips and teeth to tease the girl to another orgasm. Margo sucked on her sister's tits.
After eating each other out several more times, the fucked-out trio fell asleep in each other's arms, Karen forgetting to send her daughters back to their own rooms before their father came home.
