Family Evolution

Will looked at his sister, even in nondescript clothing he wanted to fuck her.

"I'm sorry Lex, I didn't mean for things to get that far. I should have known better," he said.

Lexi shifted closer, lifting some hair from her brother's face, "you weren't taking advantage of me. I wanted that, I want you. I have for a long time."

Will's cock lurched.

"It's not that you aren't desirable or that I don't desire you," he started, "I'm your brother. If dad was still here he'd kill me for touching you like that," he said.

Lexi smiled, "dad isn't here and even if he was he wouldn't stop me from getting what I want. I want you. You said you're supposed to beat guys up to protect me? You're beating yourself up pretty bad right now over something we both want. If your hesitation and looking out for me, for us, isn't proof you care then I don't know what is."

Will looked at his sister, "it's something we can't walk back from Lex. You can't un-fuck your brother."

Lexi smiled, "let me worry about that, I'm a big girl, I can take care of myself and right now I want what I've been fantasizing about for a long time. I want my brother's cock; I want to hear my brother moan my name, just like he did last night."

Will looked at his sister in surprise.

"I didn't mean to spy, I just intended to come down to see if you wanted to hang out a bit more, I wasn't tired. But when I saw you, and then heard you moan my name AND Daisy's..."

Lexi moaned as she looked at her brother, "I fucked myself so hard last night dreaming of you. I don't care if it's wrong to want to ride my brother's dick, I want it."

Will groaned with lust, a guy can only take so much.

He stood up and picked up his sister, throwing her over his shoulder. Lexi giggled and squealed with desire as her brother carried her into his bedroom to be fucked.

Will carried his sister into his room and threw her down on the bed. She bounced on the mattress and watched with some trepidation when he left the room, only to have her nipples harden when she heard him close the door between his apartment and the house.

Lexi propped herself up on her elbows as her brother came back into view and re-entered his bedroom. He looked down at his sister, "last chance to end this before we go too far," he said.

Lexi smiled up at her brother, "fuck me big brother."

Will's eyes flashed with lust as he moved down on the bed, Lexi giggled as her brother kissed her hungrily and started to peel clothes from her body.

First her top (no bra), then her shorts (no panties).

"Ooooohhhhh you bad girl," he grunted with lust.

Lexi smiled, "I think my big brother should punish me," she said in her best sweet girl voice.

Will took off his shirt, sweats and boxers, his hard cock springing free.

"Mmmmmmmm fuck yes," Lexi moaned when she saw her brother's cock. "So big..."

Will pushed his horny sister back on the bed and she happily complied. She watched as he gazed at her body, she had been ogled before but never like this. The way her brother looked at her gave her goosebumps. He wanted her, he wanted to ravish her and she wanted to be ravished.

Will spread his sister's legs and started to lick and kiss his way up to her sex. As perfect as her tits looked, he was a leg man first and foremost. Will kissed and licked his sister's legs, her inner thighs. His hands slipped across her smooth skin as he tasted her body.

Lexi moaned, her pussy on fire as his tongue traveled along her thighs and finally reached her sex. Will put her legs over his shoulders as he started to eat out his sister his head buried between her thighs as he licked and kissed her pussy.

Her hands moved to his head, holding him there as he ate her out. He started to finger her, one digit and then a second while he toyed with her clit. Only one of her ex-boyfriends had even bothered to eat her out and it was nowhere close to as good as this.

Lexi pushed her pussy into her brother's mouth, offering herself to him.

"Mmmmm Billy, eat me, eat your sisters pussy..." she moaned.

Will's tongue lapped at her pussy while he fingered her, faster and faster. He licked and sucked on her pussy lips as Lexi felt her orgasm rising.

"Uuuhhhhhhhhh yes yes yes yes!!" she exclaimed as her brother played with her pussy. Her body was on fire as he licked her, fingered her, sucked and slurped on her pussy.

"Mmmmmmmmm I love your pussy Lexi," Will grunted.

"Oh fuck, oh fuck, oh fuck, oh fuck..." Lexi moaned.

Will rubbed her pussy, her wetness drenching his bed, her desire feeding his own. He licked, flicked, kissed and sucked her pussy until she gave in, shuddered and came.

"Ooooohhhhhhhhh fffffffffUCK!" she grunted loudly.

"I'm cumming, eat me."

"I'm cumming, eat me."

"I'm cumming, eat me."

She repeated over and over.

Finally Will licked his lips and lifted his head, "Mmmmm, my sister's pussy tastes good."

"Mmmmmmm fuck," was all his sister was able to say.

Will looked at his sister, her hair was a mess, her chest heaved as she caught her breath, her nipples were hard - he wanted to fuck her.

Lexi felt her brother move up her body, his big hard cock dragging against her soft, smooth skin.

She happily led him lift her arms over her head as he pinned her down on the bed, his body over top of hers.

"Does my little sister want to fuck her big brother?" he taunted.

Lexi smiled and nodded.

"Does my little sister want to be stuffed full of her brother's cock?" he asked.

Lexi bit her bottom lip and nodded. "I want to fuck my big brother so bad. Fuck me Billy. Fuck your sister. Take care of your sister like you're supposed to, give me a fucking only my brother can give."

Will groaned with boiling hot lust.

Lexi's body was on fire as she felt her brother mount her, his big thick cock pressing against her. He leaned down to kiss her, his tongue probing her mouth as the head of his cock entered her pussy.

Brother and sister kissed passionately as Will pushed deeper and deeper inside his sister.

Lexi broke the kiss but kept his head close, begging for more in his ear.

"Mmmmm yes, give me that cock. Fucking hell Will, it's so big and juicy, it was made for my pussy."

Will smiled and kissed his sister again, he slid deeper and deeper into his eager sibling as she huffed and moaned.

"Mmmm holy shit Will, you're so biggggg..." Lexi moaned. She looked down at the sight of her brothers cock splitting her in two.

Will's big dick pushed deeper into his sister's pussy. He watched her face as she took more and more of his cock. She told him to stop for a moment as she repositioned herself, she looked up at her brother, "Brian doesn't have anything on you big bro..." she said huskily.

Lexi moaned loudly as her brother pushed balls deep inside her, she felt so full of cock and she loved it. She started to moan and whine with lust as he stabbed her pussy with his cock. He started to fuck her hard and slow, his cock gliding back and forth, fucking her with a purpose.

"Mmmmm yes Billy, fuck me, god yes fuck me..." she groaned.

Will leaned and dug his cock even deeper into his sister, her tits bouncing and shaking as he fucked her.

The bed shook as they fucked, Will grunted loudly as he fucked his sister, "oooohhhhh Lexi, fuck I love you. I love every inch of you. I love your pussy."

Lexi moaned, "it's yours, it's your pussy. My pussy belongs to my big brother; you can fuck me anytime you want."

Lexi and Will moaned louder and then together as they kissed, Will thrusting hard and deep into Lexi and Lexi giving as good as she got. She'd never been fucked like this, it was the best fuck of her life and it was courtesy of her brother.

Will couldn't believe the sensations he was feeling, no other woman had made him feel this alive during sex, his own sister was driving him wild.

Will pumped harder and harder into his sister, the head board hitting the wall as he fucked his sister. His balls slapping loudly as they fucked, the sound of their incestuous rendezvous filling the apartment.

Lexi looked into her brother's eyes as he fucked her, right then she knew she was hooked on family sex, on her fucking her brother. She felt his cock throb, his orgasm rise in tune with hers.

"Mmmmmm fuck me, fuck me, fuck me, fuck me," she encouraged, "I'm so close."

Lexi felt his thrusts get even harder, even faster. His body glistening with sweat, his muscles working overdrive as they fucked.

Will grunted, on the verge of exploding, "cum in me," Lexi encouraged, "it's ok, it's safe."

Will didn't need to be told twice, he thrust two more times and then popped the biggest load of his life inside his 20 year old sister as they came together in a sibling sex explosion.

Will came inside of Lexi as Lexi came all over her brother's cock. Both had to catch their breath as Will pulled out of his sister only to have her naked body curl up next to his, "that was amazing," she panted.

Will smiled and laughed, "that was better than amazing," he said, "that was like sex cocaine. That was unbelievable. Every brother in the world should be fucking his sister if it's like that."

Lexi giggled and climbed on top of her brother to kiss him, tasting his lips. "Mmmmmm, you know you're mine now don't you?"

Will grinned, "what idiot says no to his sex cocaine sister?"

Lexi bit her lip again, "mmmm good, because I'm not done with you yet tonight."

Will watched as his sister slipped down his body, not believing she still had the stamina and questioning whether he would. Lexi kissed his chest and the all the way down to the object of her desire, his cock.

"Mmmmm hello not so little Willy," she moaned.

Will groaned as he watched his sister kiss, lick and then suck his cock into her mouth. Lexi looked up at her brother, locking eyes as she moaned around his shaft.

Will groaned as his sister brought his cock back to life, bobbing on his cock as he caught his second wind. His head fell back as his sister lovingly sucked his cock.

"Mmmmm God yes Lex, you're amazing."

Lexie smiled and let her brother's cock slip from her mouth with a pop.

"Mmmmm, the feeling is mutual Billy, you don't know how badly I've wanted to suck your cock. What I would have given to bounce on your dick after a hard day in school."

She started to move up his body, teasing her brother, "I needed to fuck my big brother but he made me wait. I needed a big brother pick me up but didn't get the satisfaction..." she playfully pouted.

Will grinned, "well that just means we have a lot of time to make up for." His cock throbbed, "now be a good sister and sit on your brother's cock."

Lexi smiled with desire, her hands on Will's chest as her tight young pussy slid down her brother's shaft. Her hungry pussy eating up his cock as the siblings started another fuck session that would carry them well into the night.

Will woke up Sunday morning with his naked sister still in his bed. He groaned as he woke up, feeling his sister's body strewn across his.

"Too early..." Lexi groaned.

Will pulled his sister into him and kissed her, she kissed him back.

"More cock?" she hopefully.

Will grinned, "you drained my balls last night... and most of the morning... at least let me have some orange juice first."

Lexi giggled, "we did get a little carried away last night, didn't we?"

Will kissed his sister again, "yes we did, but we're going to have to be careful in the future. We can't let mom know an-..."

"I'm not going to hide this from Daisy," Lexi interrupted.

Will looked at his sister but Lexi shook her head, "sisters talk silly and she's going to know something is up. I might be able to keep it from her for a little bit but not long. It doesn't matter anyway, you can fuck her too."

"Excuse me?!?" Will exclaimed.

Lexi smirked, "don't act so innocent. I've seen the way you look at her, it's the same way you looked at me and you had me speaking in tongues last night," she started. "Daisy wants to fuck you Will."

"How do you know?" Will asked.

Lexi smiled, "I told you, sister's talk. And we've talked a lot about you. I'm not giving you up, not after last night, but I'm not going to deprive my own sister either," she said.

Will shook his head, "I feel like I'm in the twilight zone, everything has changed in a heartbeat."

Lexi stroked her brother's chest softly, "the sooner you accept it, the more at peace you'll be. I thought I was crazy when I first started thinking about you, but it's not like I sat up every night pining for you to break down my door and fuck me. It was one of those fantasies you have that you just hope comes through. Some women have a celebrity fuck list, I had a brother fuck list - and I only have one brother."

Will grinned, "I know. I accept it, I don't want to undo it, it's just all so... surreal," he said.

Lexi smiled, "well you better get past it, you have to pick up Daisy in 30 minutes."

30 minutes later Will was standing inside the front foyer of the Shaw family, watching Daisy bound down the stairs with her best friend Rebecca. He made sure not to get caught staring at his sister as her breasts bounced while she came down the stairs, but he couldn't help but look at her in a new light after last night with Lexi.

He thanked Rebecca's parents and grabbed Daisy's bag, walking with her to the car. He couldn't help but tease his sister, "did my little sister have fun at her sleep over?"

Daisy smacked her brother's arm, "We had a lot of fun if you must know, it was fun to have a sleep over before grad, kind of like a goodbye to one stage of life, you know?"

Will looked at his sister and then turned his eyes on the road as they pulled out of the driveway, "just like you to put an adult spin on growing up."

Daisy smiled and leaned over to kiss her brother's cheek, she sensed something was different. Daisy lingered for a moment, looking at her brother, "so, what did you do last night?"

Will paused then looked at his sister, "nothing much, just hung out with Lexi."

The rest of the day went by pretty quickly; Will was pretty impressed with his ability to maintain some normalcy around Lexi. Will made tacos for the entire family for lunch and everyone, Mary included, spent some time outside by the pool.

Will started working in his shop on Monday distracted with thoughts of his sister's. He always found it peaceful to work in his wood shop, it felt good to make something with your own two hands but he couldn't get Lexi and Daisy out of his mind.

Lexi had said Daisy wanted to fuck him and truth be told, he wanted to fuck her. Maybe it was his mind playing tricks on him but she seemed to be teasing him Sunday afternoon by the pool. The way she bent over, the way she stretched, hell, even the way she put sun tan lotion on their mother.

It's one thing to want to fuck your sister, but it's not as though he could just walk up to her and throw her down on the bed and do it (even though he probably could based on what Lexi had told him).

Despite his growing desire to fuck his youngest sister Will didn't want to rush things. He hadn't been with Lexi again yet and that was a major development in itself. He decided to let it happen as natural as possible and got back to work.

The rest of the week progressed with Will plotting a way to bed his youngest sister while he and Lexi continued to hook up. She was scheduled for evening shifts at the restaurant that week and used the free time during the day to ride her brother's cock at home while her mother was at work and her sister wrapping up her final week of school.

Lexi loved to ride her brother's cock and fucked him all over the house, in the kitchen, the living room, her room and his wood shop. Will fucked his sister like a man who was about to go away on a six-month tour at sea. The two horny siblings even made their own dirty sex tape, Lexi wanted to see what they looked like together and fucked her brothers brains out for their secret movie.

Will had to admit their video was hot, it started with Lexi sucking and then deepthroating his cock, progressed into the two 69ing before Lexi got on top of her brother and bounced on his cock.

Will groaned with anticipation as Lexi rubbed his shaft along her wet pussy, she grabbed his cock and slapped it against her pussy. Lexi looked over at the iPad filming their illicit rendezvous, "there is NOTHING I like more than riding my brother's cock."

And with that, Lexi's drooling, tight, wet pussy started to slide down her brothers pole. She propped herself up on his chest while her pussy moved deeper and deeper.

"Mmmmmmm fuck it's so big, you fill me up bro," she moaned.

Will smiled, Lexi had really started to enjoy calling him brother during sex.

Lexi bit her lip as she pushed deeper on his cock, "aaaaaahhhhhhhhh..." she moaned as she slid balls deep.

Lexi leaned down and kissed her brother on the lips, "you're the best brother in the world..." And with that, she started to ride his cock. Will lay back at first, enjoying the way his sister pleasured herself on his cock, the sound of their bodies slapping together during sex becoming strangely hypnotic.

Will grabbed his sister's body as she moaned and groaned above him and started to fuck her back. Lexi moaned and whined with lust as her big brother started to take over and fuck her back. She loved the way he held and grabbed her body, pulling her into him so he could fuck her deep and hard.

Will and Lexi fucked like all-stars for their dirty homemade movie. Will flipped her over and fucked her, he put her on all fours and fucked her, Will fucked her tits and then returned to her pussy, pounding her over and over until they came together and he creamed inside her. Their dirty movie ended with Will's cum leaking out of his sister's freshly fucked cunt.

The sex was incredible, it was mind blowing but with every stroke his cock made inside his sister he knew it would become more and more difficult to ever stop. It was like a drug and he couldn't believe how good it was. The more he fucked Lexi the more he wanted to fuck Daisy as well and he had devised the perfect plan to do just that.

~

Will didn't need an elaborate plan to seduce Daisy, but he wanted to do something special. His plan centered around her graduation so he waited until the big day to put it in motion.

Mary, Will and Lexi were proud as could be on Daisy's graduation day, plenty of pictures were taken and the three shamelessly cheered for her when she got her diploma, only partially trying to (playfully) embarrass her. After her graduation they went out for a celebratory dinner before Daisy went out to really celebrate with her friends.

The next day Will knocked on Daisy's door. A groan came from inside.

"Mags? It's Will," he said.

"Ughhhhcomein..." she muttered.

Will chuckled as he entered his sister's room to find her lying in a tangled mess on her bed.

"Have fun last night?" he teased.

"Ugh," she grunted in response.

Will chuckled, "I'll take that as a yes," he said.

Will sat down on his sister's bed and softly moved some of her hair from her face. "I was thinking, if you aren't in too rough shape, you and I could go out for dinner tonight like old times, just the two of us, to celebrate."

After their father died Will had tried to fill the void by establishing new family traditions, individually with his sister's and mother, and for the whole unit as a way to help them all move on. Something he and Daisy had done was go out for meals together and turn it into a brother-sister date night, just the two of them, something both enjoyed. Will liked being with Daisy and making her laugh and Daisy always cherished their one-on-one time.

Daisy perked up at the suggestion, her head lifting from her pillow. "Just the two of us?" she asked.
