Allison had long suspected her mom and Billy had a thing for each other. Watching them now, with her brothers cum dripping from her mom’s mouth, as they starred deeply into each other’s eyes and telling each other how much they loved each other, confirmed it beyond a doubt.

“That was hot!” Allison exclaimed. “Now it’s your turn mom.” With that she turned to Billy and said.
“Get up Billy and let mom take your place. Mom take your clothes off. Let me show my little brother how to eat his mom’s pussy.”
“What?” Cheryl said confused. “He can’t do that, it’s not right. I’m his mother!”
“Yes mom, you are his mother. And you just sucked his dick. He should return the favor. As his mom you have the responsibility to teach him proper etiquette. It’s only polite for a guy to return the favor if he’s had a good blowjob. You want him to respect women both in and out of the bedroom, don’t you?” Allison reasoned
“Well, yes, I suppose.” Cheryl replied.
“How long has it been since you’ve had your pussy eaten mom or had sex other than masturbation?” Allison asked
“A long time.” Cheryl said with a sigh.
“You’re a young, beautiful woman mom, and you deserve the pleasures of a young, beautiful woman. Now, strip and let us take care of your needs.” Allison said
“I don’t know?” Said Cheryl. “I’m a bit shy about Billy seeing me, his mom, naked.”
“Well look at him mom! Standing there with his cock and balls out for all to see. And what about me? Here I am naked and I just rubbed an orgasm out in front of him and you. Come on mom, I know you want Billy’s tongue on your pussy. Just imagine what it will be like to look down into his eyes as he eats you out? And I bet he’d love to do it also. Wouldn’t you Billy?” She said turning to her brother.
“Sure, I suppose.” Answered Billy, a little unsure.
“Oh come on you two. I saw the way you looked into each other’s eyes just now. You two are very sexually attracted to each other. Don’t you want to see mom’s sexy body Billy?”
“Yes, yes I do.” Billy said

With just a hint of an outright order Allison then said:
“Come on mom, strip, show Billy your sexy body.”

Cheryl arose from her knees, turned around and said to Billy
“Unzip my dress for me sweetie.”
Billy unzipped Cheryl’s dress and she slipped it off her shoulders letting it fall to the floor.
“Now unhook my bra, ok” Cheryl said
Billy began to fumble a little with her bra but soon unhooked it. Cheryl then slipped the straps from her shoulders as she grabbed the cups, turned around to face Billy and looking him in the eyes dropped her hands. Her bra feel to the floor and she revealed her breasts to her son. Although not as big as Allison’s C cups Cheryl had very firm and shapely B cup breasts topped off with medium sized soft, pink areola’s. Standing there in only her white cotton panties she was a very arousing 40 year old milf with her slim figure, flawless skin and average hips. It was very obvious where Allison had gotten her looks.
“Doesn’t mom have sexy tits Billy?” Allison exclaimed, as she stood up and grabbed one in her hands.
“Such suckable nipples. Come on Billy, I’ll take this one and you take the other.”
With that Allison lowered her head and took Cheryl’s right nipple in her mouth at about the same time Billy, eagerly took the left in his mouth. Cheryl immediately gave a quite sigh of pleasure as her son and daughter jointly sucked on her long neglected breasts.

Allison’s hands began to explore Cheryl’s body and soon found their way to her panties where she slipped her hand inside and felt Cheryl’s tightly trimmed pubic hair.
“Billy, slip mom’s panties off.” Said Allison.
Billy eagerly stopped sucking on Cheryl’s tit and pulled her panties down to the floor. Cheryl’s brunette pubic hair was trimmed and shaved into a nice, clean, extremely attractive triangle. Her genitals, which she kept clean shaven, were a very feminine pink with average size outer labia and hooded clit. As Cheryl stepped out of them Allison said.
“Look at mom’s beautifully trimmed pussy Billy. Sit down on the couch mom and let Billy and I take care of you.”
Now all three were naked and as Cheryl set on the couch Allison dropped to her knees in front of Cheryl and said to Billy.
“Come on little brother, get down here with me on your knees and let me show you how to please a woman.”
“Your pussy is so beautiful mom. I especially love the triangle pubes.” Allison placed her nose into Cheryl’s crotch and gave a sniff.
“Ummm…I just love the smell of pussy. It’s so fucking arousing. Smell mom’s pussy Billy.”
Billy leaned forward and smelled his mother’s pussy while Allison licked her index finger and began to lightly rub her mother’s clit.
“Doesn’t mom’s pussy look and smell so sexy Billy?” Allison asked her brother.
“Yes it does.”
“Guess what?” Allison said
“What?” Responded Billy
“It bet it tastes even better. Why don’t you taste her, lick her sexy pink lips Billy.”
Cheryl was already beginning to feel the effects of her daughter’s skillful finger on her clit as her son leaned forward and licked her labia with his tongue. This caused Cheryl to let out a soft long awaited moan.
“Keep going Billy. Lick mom’s sexy pussy. Pleasure your mom the way she pleasured you Billy.”

Billy continued to lick Cheryl’s sexy labia as his sister massaged her clit. Billy really loved the taste and smell of his first pussy and began to get really into eating out his mother. Cheryl began to moan deeper and deeper and louder and louder as her son and daughter jointly pleasured her. After a minute or so Allison said, as she removed her finger from Cheryl’s clit.
“This is mom’s clit Billy, it’s very sensitive and girls really love it when you lick them here. Lick it along with her pussy Billy.”
Billy did as Allison said.
“Now lick her pussy a little and then back to her clit. Then take your tongue to the bottom of her pussy and lick all the way up to her clit. Stay there and lick for a little while and then go back down to her pussy. Lick her whole pussy area Billy. Just listen to her moans and see what seems to make her feel the best and concentrate on that.”

Billy by now was under Allison’s spell and being very susceptible to instruction followed his sisters direction. Allison meanwhile had moved up to Cheryl’s tits and began to suck and caress them very sensually. Cheryl reached for her daughter’s magnificent breasts and began to feel and caress them. She loved how soft, smooth and sexy her daughter’s beautiful full breasts felt in her hand. She soon began to moan deeper and deeper as her offspring pleasured her sexually. Allison knew she was ready to be brought to orgasm and wanted her to climax with Billy’s uncut cock inside of her. Allison reached down and felt between Billy’s legs. Being a horny young teenager of course her brothers cock was close to fully erect so she began to work his shaft to bring him fully erect as she leaned forward and whispered into his ear.
“Keep eating mom’s pussy while I suck your dick to get it good and hard.” Allison instructed him.

Allison then lowered herself between her brothers legs and took his manhood into her mouth. She skillfully sucked his dick and massaged his sack, preparing her brothers tool to enter his mother. Soon Billy was well lubed with Allison’s saliva and rock hard. Allison raised up and placing her hand on Billy’s head pulled him away from Cheryl’s pussy, then she reached in and placed her thumb on her clit as she inserted first one then two fingers into her mother. Cheryl was very aroused and Allison knew that even Billy’s rather substantial dick would slide right in. As she continued to masturbate her mother she leaned in and whispered to her brother,
“Mom’s ready for you to fuck her Billy, lean in and let me guide your cock into her pussy.”
Allison then reached for Billy’s dick as he rose up and moved to enter his mother. She guided Billy’s cock into her mother’s fuck ready pussy.
“Ok Billy, go slow but smooth all they way in.”
Billy’s hips moved with a natural smooth motion as he buried his fully erect dick balls deep into his mother’s pink pussy for the first time.

The feeling for both Cheryl and Billy was like nothing either had ever felt before.

Billy, instinctively, began to fuck his mother with smooth, fluid and rhythmic hip motion. Backing almost all the way out and then thrusting with authority all the way in, giving Cheryl the experience of the entirety of his sex organ in her pussy.
“Oh yes Billy…” Cheryl sensually remarked “fuck me good, fuck me good Billy. That feels so wonderful, please don’t stop.”
Allison, meantime, reaching just below her mother’s clitoris to moisten her finger tip with her mother’s natural lube returned to skillfully massaging her now swollen clit. The combination of Billy sensually thrusting her womb and Allison’s journeyman like masturbatory skills on her clit caused Cheryl to sink into a state of deep pleasure.
“That’s it Billy” Allison softly remarked to her brother, “that’s a good boy. Keep it up big guy.”
Billy exuberantly continued. The feeling of his dick sliding in and out of his mother’s warm, wet, perfectly matched pussy as his low, saggy ballsack slapped lightly against Cheryl’s lower buttocks was an ecstasy he never could have imagined. Neither he nor Cheryl ever wanted this to end. Allison, meanwhile, was massaging and pleasuring her mother’s clit with such artful skill as to begin to bring her into waves of near orgasm, only to back off with perfect timing, causing Cheryl to go through wave after wave of edging.

Allison was a master at edging and had practiced her techniques many times, not only on herself, but on others, both guys and girls, as well. She was focusing all her concentration, abilities and skill to guide both her mother and brother to achieve maximum orgasm at the same time.

“That’s right Billy, long, smooth, full strokes. Billy’s cock looks so sexy fucking you mom.” Allison said.
Billy was truly getting the hang of it as Allison brought her mother through several waves of small, medium and almost full orgasm only to back off, prolonging and building to her final explosive climax. Because Billy was young and had already cum twice today, including once just a few minutes earlier, his ability to prolong his orgasm yet also maintain full erection was at a peak state. Again Allison, due to her experience, knew that. Soon she could sense that Billy was close to releasing his load. Allison knew the time had come and began to focus her attention on Cheryl’s swollen clit. Cheryl began to moan deeper and deeper and soon her whole body began to tremble.
“Faster and harder Billy” Allison softly remarked. “Fuck her faster and harder.”
“Oh yes!” Moaned Cheryl. “Fuck me Billy! Fuck me good! Pound my pussy good Billy!” Cheryl exclaimed.
“You heard her Billy,” Allison said forcefully “Fuck her hard Billy while I rub her clit. Fuck her good. Give her every inch of that sexy dick!”
“Oh yes!!” Cheryl said loader “Rub my clit! Fuck my pussy! Give me your cum Billy! Please, Please! PLEASE fill me with your cum!!!!!”
“Fuck her Billy! Fuck her good! Pound her pussy give her a load!!” Allison exclaimed forcefully as she rub her mother’s clit with perfect pressure.
“Yes!! I’m cumming!! Oh yes! Don’t stop!! Please don’t stop!! Fuck me out Billy! Please fuck meeeee!!l” Cheryl screamed.
Then she began to tremble and squirm so forcefully Billy had to grab her hips to hold her in place as he pounded even harder.
“Cum Billy!!! Fill her full Billy!!” Allison shouted “Fill that pussy full!!!
Drain your balls Billy! Release your load!”

With one final powerful thrust forward Billy sank his cock balls deep, then immediately released his load to fill his mother’s pussy with her son’s seed. Then, backing off, thrust again to release another. With his cock buried deep in his mother’s womb as his sister rubbed her clit a final few times and she writhed in ecstasy Billy froze in a state of pleasure and final fulfillment.

After an extended moment Billy and his mother soon starred deep into each other’s eyes. He moved down as she arose to meet his lips and with his softening cock still inside her cum filled pussy they embraced in a deep passionate kiss. Knowing they had consummated their relationship in a very special way.
