Family Evolution Ch. 03

Mary heard her daughters from the kitchen, she paused for a moment as she thought of her chat with her son, her many talks with Sherrie and the images still seared in her brain of when she caught them together and couldn't help but wonder what would come next.

~

What came next was a return to normal, as best can be expected when three quarters of a family is in an open sexual relationship.

Will continued to sleep with his sisters individually and during threesomes, they had sex primarily in his bed but would get more adventurous when they knew Mary would be gone for an extended period of time.

Mary often caught her daughters cuddling up to their brother as they watched tv and was aware that Daisy in particular had developed a habit of sleeping in her brother's bed even when they weren't having sex.

As much as Will, Lexi and Daisy diligently tried to keep their illicit family rendezvous from her, she could always tell, and sometimes hear, especially when Lexi was riding her brother's cock.

Mary was conflicted. On the one hand she knew they were too far down the rabbit hole to stop now, on the other hand she was still concerned they'd get caught and wasn't entirely at peace with it all. There was also a growing nagging desire inside of her to catch them together again.

One day in the middle of the week Mary decided to take a half day off from work. It was a beautiful warm and sunny day and she didn't want to spend all of it inside an office.

Lexi was at work but Will and Daisy were at home working in his wood shop, she thought maybe they could all go get some lunch and go down to the beach.

As Mary arrived home she quickly deduced her son and daughter weren't inside taking a break, or downstairs taking a different kind of break, but instead in his shop.

Mary walked around back when all of a sudden she heard a moan coming from Will's wood shop. She thought about turning around and going back inside but was drawn to the wood shop to see and hear more.

Mary quietly walked to the wood shop and peered in, what she saw was Daisy naked on her brother's work desk, with her brother's head buried between her thighs.

Daisy moaned loudly as her brother ate her out, "I love your tongue Billy, you're driving me wild! More! More!"

Will groaned as he ate his sister's sopping wet pussy, she had suggestively bent over the desk and he wasn't able to stop himself.

Will's hands gripped Daisy's thighs as he licked and sucked on her sex. Daisy's fingers zigged and zagged through her brother's hair as she fed her brother her pussy.

Will's tongue worked overdrive as he sucked her pussy, he moved two fingers down to start to finger fuck her while he toyed with her clit.

Mary was stuck in a state of shock and euphoria as she watched her son and youngest daughter but couldn't look away.

Daisy moaned louder and louder as her brother toyed with her pussy, "mmmmm yes Will, yes yes yes yes YES!"

Will lifted his head from between his sister's thighs and licked his lips, lust written all over his face. Daisy looked at her big brother and bit her bottom lip, "whatcha gunna do to me big brother?"

Mary heard her daughter moan as Will lifted Daisy off the table and bent her over it, he spread her legs wide and started to slide his cock inside of her.

Will finally answered his sister, "I'm going to give my little sister a fucking only a brother can give."

Mary watched as Daisy's head drooped down as she moaned while Will's cock filled her up.

Daisy moaned as Will started to fuck her from behind. Will pulled back and thrust deep inside of her, making sure she felt every inch of his shaft.

Daisy started to grind against her brother's cock as he fucked her with slow, long and hard thrusts, savoring the feel of his cock.

The sound of their sibling mating filled the workshop as they fucked in the middle of the day, Will's cock drilling deep into his sister's pussy.

Will leaned down and licked up Daisy's spine as he fucked her, knowing she loved it when he did that. As he lifted his head from her neck he saw something in the window.

He continued to fuck his sister as he tried to determine what he saw. Was that a person? Had they been caught? It couldn't be a customer; they'd have to buzz the shop to get in through the fence. Was it Lexi? If it was she would have joined them by now.

Daisy moaned again as Will fucked her faster and faster, that's when he saw who was spying, it was their mother.

Mary peered in the window again as Daisy moaned loudly, she was worried she had been caught peeking but Will and Daisy hadn't stopped so she assumed she was ok.

She watched as Will picked up the pace and fucked his sister faster, Will saw his mother out of the corner of his eye and smiled as he concentrated on Daisy.

Mary watched as Will and Daisy paused momentarily so Will could sit back and Daisy straddled his lap, she watched as her youngest daughter impaled herself on her brother's cock and started to ride him.

Will loved it when his sisters rode his cock and Daisy loved to bounce on her brother's dick.

Will was determined to put on a show for his mother so he thrust up to meet Daisy as she bounced on his cock.

Daisy leaned down to kiss her brother, unwittingly showing her mother a moment of tenderness amidst their lusty sibling fucking. Will kissed his sister back, holding onto her body tightly as he fucked her deep and hard.

Mary's hand was inside her panties as she watched her kids together, it was all too much. The way Daisy kissed her brother, gripped him and rode him. The way Will ate her out, fucked her and held her.

Their bodies glistened with sweat as they fucked in the hot and muggy workshop. Daisy's breasts rubbed against her brother's body as they fucked each other totally and completely.

"Never stop fucking me Will," Daisy breathed in his ear.

Will looked into his sister's eyes, "I'll never stop fucking you Daisy," he said, loud enough for Mary to hear.

That was enough to send both mother and daughter to orgasm as Daisy started to shake on top of her brother while Mary turned away from the window and came on her fingers.

Mary heard her son and daughter cum as Daisy bounced harder on Will's cock until he exploded inside her.

Will and Daisy slowly came down from their high as Daisy stayed on top of her brother's lap.

Will waited until he heard their mother leave before he told Daisy what he saw.

"Mom was watching!?!" Daisy exclaimed.

Will nodded, "I don't know when she started but she must have watched most of us fucking."

Daisy smiled, "do you think this means she's ok with it?"

"I don't know," Will said, "let's not force it and see what happens."

Daisy smiled and kissed her brother again, "I hope she's into it, it would make things so much easier - and hotter."

~

Mary never did go out for lunch with Daisy and Will after watching them together. As hot as she felt watching them, she felt the exact opposite afterwards.

She was conflicted about her response she faked a sickness that night to avoid having to look her family in the eye.

Will didn't push it with Mary but he did notice a certain Jekyll and Hyde attitude develop with his mother. At times it was like it had always been, but other times Mary was withdrawn and moody.

Will noticed his mother peeping a couple more times over the next few weeks and decided to help his mother along with her mixed desires.

One day Mary came home and found a package on her nightstand. It was two DVD's with a note on top from Will.

"Mom, it's been a crazy summer for Lexi, Daisy and I so I can only imagine what it's been like for you. You've been supportive and we love you for it but I know you're still conflicted. Here's something so you don't have to sneak around, I hope it helps. Love, Will."

Mary didn't know what she was looking at first, but she had an idea. She closed her bedroom door and put the first DVD in her DVD player.

The second something popped on her screen Mary knew she was looking at she had suspected, Mary was looking at a collection of sex tapes her children had made.

The first video included only Will and Lexi. Mary thought for a moment about turning it off but couldn't find the willpower.

Lexi was on the screen, naked and on her bed from the looks of it. Lexi called out to her brother to join her on the bed.

"Willllllll, I'm horny!" Lexi whined with lust.

Mary immediately shuddered with lust as she listened to her daughter and watched as she lewdly started to touch herself and play with herself to entice her brother to join her.

Mary again thought she should turn the DVD off but made no effort to do so.

"I'm coming Lexi!" Will responded, "I was just making sure everything was set up and taking off my boxers."

Will walked into the frame and Mary saw her son's hard thick cock as it bobbed while he walked. "I wanted to take your boxers off," Lexi purred.

Will grinned as he got on the bed and pinned his sister down. Mary watched as her son started to rub Lexi's wet pussy, kiss her and then whisper in her ear.

"Say it so the camera can hear you big goof!" Lexi said, smacking her brother.

Mary couldn't help but smile as she watched her son and eldest daughter, even naked, horny and about to have sex they were clearly still brother and sister, a realization that comforted her.

Will rolled his eyes and looked back at the camera, he paused and then smiled, and Mary felt like he was talking directly to her. "I'll make it up to you, I'll make you squirm and cum."

Lexi moaned on camera and Mary moaned with her, her hand snaking inside her panties to touch herself as she watched Will turn his attention back to his sister.

He pinned her down and started to lick and kiss Lexi's body. Lexi squirmed with desire as her brother kissed her lips, her cheek, her neck and her chest. His tongue started to lightly lick and tease her nipples before he traveled further south down her body until he reached her wetness.

Mary watched as her son started to eat his sister's pussy and thought of how long it had been since someone did that to her. Lexi moaned with lust and started to pinch her nipples while her brother ate her out.

The angle wasn't perfect but Mary could see the way Will licked and sucked on his sister's pussy. His tongue teased her, his fingers started to rub her and finger her and his head stayed buried between those sexy thighs of hers.

How many men have tried to get between Lexi's thighs? Mary suddenly wondered, probably many. She snickered at the thought of all those men and boys failing all because they suffered from one fatal flaw: they weren't Lexi's brother.

Mary's skirt and panties were now off as she watched Will lick and eat his sister's pussy like only a brother can. Lexi's moans were impossible to miss and grew in intensity until she started to shake and cum because of the attention of Will's tongue.

"Ahhhhhhhhh fuck fuck fuck fuck fuck fuck FUCK YES WILL!" Lexi moaned.

Lexi grabbed his head as he licked and slurped on her juices, Lexi's orgasm washing through her body.

"Mmmmmm fuck I love your tongue Billy..." Mary's daughter moaned to her brother.

Will lifted his head and licked his lips, a smile plastered on his face, "I love your pussy Lex."

Lexi smiled, "how much do you love it?" she teased.

Will moved back up Lexi's body, his cock dragging against her soft skin, "mmmmmm this much," he said as his cock started to sink inside of her.

Lexi moaned something that Mary couldn't understand but it didn't matter, the pleasure was written all over her face.

Mary watched as Will's cock slide deeper and deeper inside Lexi until he was balls deep. Mary furiously fucked her pussy as Will pulled back and thrust inside of Lexi's.

Will started to fuck Lexi hard and slow, fucking his sister with a purpose. Lexi's legs wrapped around her brother as he fucked her, locking the siblings in their taboo embrace.

Will grinded his cock into Lexi harder and faster, his sister meeting his thrusts, giving as good as she got. Will fucked Lexi harder and harder, the bed starting to shake as they fucked.

"Fuck me big brother!" Lexi yelled as her brother obliged.

His balls slapped loudly against her body as their bodies combined in a taboo mesh of love and lust. Will's muscles tightened as he thrust again and again into his sister, his thrusts never stopping or slowing as he fucked his sister with the stamina only a young man possess.

Will and Lexi kissed hungrily as they rutted like animals, their mutual desire for one another painfully obvious.

Mary now had a dildo working in and out of her as she watched her children's sex tape. Mary watched as Lexi rolled Will onto his back and started to bounce on his shaft.

Mary shuddered with lust as she watched Lexi lift off her brother's cock before impaling herself on it. Lexi's hands were on Will's chest as she propped herself up on his body, eagerly fucking her brother.

"Mmmmm fuck Lexi, God I love you. I love every inch of you. Ride my cock sis..." He groaned.

Lexi moaned and smiled, speeding up as she bounced on her brother's dick, "I'll never ever stop fucking you Will. Never. Even if I get married one day I'll still fuck you. My pussy will always be yours."

Will groaned loudly at his sister's words, Mary watched as he thrust up to fuck her, responding the only way he could, lust making speech impossible.

"Holy fuck" thought Mary as she watched her son and daughter fuck each other.

Their thrusts increased as their lust boiled over. Will grabbed his sister as she moaned out as they came together.

"Cum inside me Will! Cum in my pussy! Fill your sister up!" Lexi screamed.

Will thrust hard up into his sister as his cock throbbed and then exploded his brotherly cream filling Lexi's pussy.

"Uggghhhhhmmmmmfuck YES Lexi!!" He groaned, his lust at an all-time high. "Take your big brother's cum! I'm never going to stop cumming in you! I'll cum in you when you're 30, 40, 50 and 60, I will never stop fucking my sister!" Will bellowed as he came.

Mary couldn't help herself and shuddered and came all over her dildo as she listened and watched her son and daughter.

Mary's entire body tingled as she pressed stop, her heart racing with excitement.

That wasn't the only video Mary had the option of watching, there were many others. That night she found herself watching another, this one starring Will and Daisy. It wasn't as raunchy as the Will and Lexi version, but was equally as erotic.

"Are you sure you want to do this?" Will asked off camera.

Daisy responded, also off camera, "you and Lexi have done this right?"

"Yes we have bu-..." Will started, "then I want to make one too," Daisy said as she interrupted.

Mary could hear her son chuckle as he stopped questioning his youngest sister, she watched as both walked into the frame of the camera and sat down on the bed.

Will was wearing a pair of boxers, Daisy a skimpy little pink nightie that left nothing to the imagination. Will sat down on the bed and Daisy joined him, straddling his lap and clearly enjoying the seat.

Daisy's hands went around her brother's neck as his hands slipped down her body. They started to kiss as if they were longtime lovers and not brother and sister.

"Where did Daisy learn to kiss like that?" Mary wondered to herself as she squirmed while watching his son and daughter kiss. It was intense and erotic and it made Mary blush.

Daisy broke the kiss and smiled at her brother, "how was that?"

Will smiled as he stroked his sister's face softly, "it was great, you don't have to be so concerned. You're an awesome kisser."

Daisy beamed as her brother complemented his kissing skills; Mary watched as she pulled herself even closer to her brother, "I just don't want to be some uncoordinated geeky newbie for you..."

Will chuckled, he leaned in to kiss Daisy before continuing, "believe me that's not what I'm thinking Mags, I'm thinking my hot little sister is all grown up and she's grinding on MY cock - and I like it."

Daisy giggled and kissed her brother again, their second embrace as steamy and hot as the first, "mmmmm well get used to it big brother."

Mary brought out another dildo as she watched Will lift Daisy up on screen, her daughter squealing with happiness. Will lifted Daisy up and then laid her on the bed like a delicate flower. Brother moved over sister as he started to slip the nightie from her curvy young body, Daisy was so excited she had goosebumps as Will tossed her nightie onto the carpet.

Mary saw lust and desire in her son's eyes as he gazed at the naked form of his 18-year-old sister. Daisy bit her bottom lip and smiled at her brother as she crawled to the end of the bed, "come to me big brother," she moaned.

Will listened to his sister and groaned as she pushed his boxers down letting his cock spring free.

"Mmmmmmm" Daisy moaned as she licked her lips and started to lick her brother's

cock.

Daisy grabbed the shaft and started to lick and kiss her brother's cock as he moaned with delight, "mmmmmm yes Mags..."

Will's head fell back as Daisy started to take her brother's cock in her mouth, sucking his cock like she'd been doing it for years.

"Oh my god..." Mary breathed as she watched her youngest daughters head bob on her brother's cock. Daisy looked up at her brother and smiled as she sucked his shaft.

Will lifted some of Daisy's hair out of the way as her lips glided up and down his shaft, his groans non-stop at this point. Mary had no way of knowing it as she watched but at the time of the making of the sex tape Daisy had been in a habit of sucking her brother's cock each and every day, wanting to be as accomplished at sucking Will's cock as Lexi was.

Mary watched as Daisy stroked Will's cock while she sucked it, pulled off his cock so she could plant kisses along his wet shaft which resulted in Will's cock smearing against Daisy's face which made Will groan with lust on camera and Mary moan in her bed.

Daisy then returned to sucking her brother off, inhaling his meat once again as her breasts jiggled back and forth.

"Mmmmmm Daisy I love you so much," he moaned.

Daisy smiled and stopped sucking her brother for a moment, "really?"

"Really," he answered.

Daisy smiled, "mmmmmm I love you too. You're the only man I want, the only man I've ever wanted. I know that's weird but..."

"You're my weird little sister and I'm your weird big brother and I wouldn't have it any other way," Will said.

Daisy smiled as Will pushed her back on the bed and moved over top of her, mounting her. Will leaned down to kiss her soft pouty lips once again as her legs spread wide for her brother.

Mary's heart pounded, her pussy slick as she watched her son and daughter together. Will planted little kisses over Daisy's body before pressing his cock against her pussy.

"Make love to me Will," Daisy asked, her body open to her brother the way it had never been to any other person.

Mary watched as her son did as his sister requested, while his fuck session with Lexi had been animalistic and raw, this was more loving and tender.

Will's cock slid deeper and deeper inside of his sister as he started to fill her up and thrust nice and slow. His arms wrapped around her as he held her tight and safe, his hips thrusting back and forth.

Will and Daisy kissed again as Will's cock filled his sister completely. Daisy started to grind back against her brother as he pulled back and slid back inside of her.

Will and Daisy moved together like seasoned lovers, they made love as if they had done it thousands of times, Will knowing just how to touch and please his sister.

Daisy's whimpers turned to moans before they were muffled by another kiss as Will's cock drove back and forth inside his sister.
