Seth walks up the stairs, his body covered in a light sheen of sweat, his muscles taut and his cock hard. He has just finished his patrol but his thoughts had started to wander and in their wandering had drifted towards a tanned, lithe and curvaceous body. Her long, lean and toned legs bent at the knees hiding her most special parts from his eyes. But as a lustful and aching growl escapes his lips do her legs begin to slow slide down and open for him. Her full breasts exposed to him first, the nipples already hard and the aureoles pebbled with goose bumps. His eyes had traveled down to her wet sex as the scent of her arousal was already on the tip of his tongue. Her small hand sliding down between the valley of her breasts, past her stomach and cupping her warmth as a seductive moan escaped her lips.

That image has haunted Seth and to make sure that no one else saw it he started full out running, running as fast as his legs would carry him until Quil phased in to relieve him. Seth had hoped that after Leah's heat that his urges for her would've passed, melted with the morning sun's rays. Instead the hunger remained and he was denied the satisfaction of tasting her again because of Sue and the rest of his brothers. Leah picking up an actual job wasn't helping matters either because when it only shortened the amount of time the two siblings had for one another.

Stomping up the stairs he growls in frustration because Leah was working at the lodge tonight. Stopping at the top of the stairs trying to catch his breath, Seth's hand grips his hard cock and he can't help but curse the tourist seasons. At this very moment Leah was probably acting as a waitress at some well-to-do lodge party where she was wearing some simple black pencil skirt and a white button-up shirt. Some guy was admiring her legs and thinking about how tightly she'd hold onto him with those sexy legs of hers.

His fist clenches tightly before he releases his cock and continues down the hall towards his room. It wouldn't do him any good to let his thoughts go to that dark alley of his usually happy-go-lucky and carefree mind. However, Seth can't deny the fact that he doesn't dislike the emotions that Leah brings up in him. He likes the way she makes him feel, the way his body aches is like a new feeling, and a sensation that makes him feel alive – almost. Being buried deep within her was the most awesome feeling in the world. She was always tight, so wet and hot.

A shower – he'll definitely need to take a shower. Getting off was hard to do with his hand and some kind of lubricant. His cock seemed to have already learned the difference between Leah's honey and some simple, cheap lotion. Even his cock seemed to only want to be held by Leah, to feel her thin fingers grip him tightly, her small palm work him up and down before roughly handling his balls.

"Calm down, man." Seth mumbles to himself as he turns to walk into his room. His cock is so hard and feels ready to bust – bust inside of Leah. Squirt his seed deep inside of her, feeling it mix with her own juices or watch it squirt out over her face, see the small dirty smile on her beautiful face as her tongue flicks out trying to lick it up as it shoots out like a fountain.

"Now why would you need to calm down?" Seth's head shoots up from his cock to see Leah sitting on his bed. She giggles at his wide-eyed and surprised expression. He's certain that he looks like the fresh catch of the day.

Seth's eyes quickly take in Leah's body. She's sitting on his bed Indian style and a comic book in her lap. Her hair is tossed carelessly over her left shoulder exposing her neck to him under the soft light of his bedside lamp.

"You really need to branch out in your comic selections." Leah says as Seth slowly walks towards her. He feels drawn to her as if there's some kind of pull towards her – there is a pull and it's tied to his cock.

"Start reading some of your Japanese comic books?" Seth asks with a smirk as he kneels on his bed and closes the gap between the two of them.

"It's called manga, thank you very much." Leah states matter-of-factly.

"Right, right…manga," Seth repeats slowly, nodding his head and removing the book from Leah's lap. His other hand grips Leah's hair, pulling her head back as he looks down at the body that he was just craving. "I – I thought you had work." Seth states as his nose grazes up Leah's neck, inhaling her sweet scent before tracing her lips.

"They didn't need me." Leah says with a playful smile on her lips.

"I'm glad," Seth breathes out before capturing Leah's lips with his. He kisses her lips sweetly enjoying the taste of them for a moment before pulling away. "because I really need you right now." Seth says placing Leah's hand against his hard cock.

"I see that." Leah says wrapping her hand around Seth's cock and squeezing him.

Their tongues meet in a heated duel for dominance that Seth is pleased to find himself winning. Tonight was turning out better than he had ever hoped because every wolf would be at home, Sam's or patrolling not thinking of coming to the Clearwaters since Leah would be at work. It meant that after two weeks Seth had his sister all to himself.

His hands quickly grab the hem of Leah's shirt and lift the simple tee up and over her head. His breathe hitches as he sees her breasts fully exposed to him – Leah doesn't bother with a bra anymore as it'd only be something else to keep track of it she had to suddenly phase. His head dips down to captures one of the dark nubs into his mouth as he sucks and nips greedily. Leah's moan only encourages him on as his other hand massages and kneads the unattended breast.

Seth loves hearing the way Leah gasp as he tugs at her nipple roughly, the nub in between his teeth as the other is twisted. He loves watching as the twisted nipple slowly rotates back to its original position still hard and desperate for his hot, wet tongue to lick it better.

Taking the other nipple into his mouth Seth begins to pull down Leah's shorts. The smell of her arousal assaults his senses, wrapping him up in its sweet scent and making his mouth water. Pulling back he yanks Leah's shorts off and practically tears his off as well in his excitement to be inside of her again, to stretch her walls.

Seth pauses for a moment to take in Leah's body. Her breasts are fuller since their first time and her hips are still swollen. He can't help but feel a sense of smug satisfaction that Leah has kept her sensual curves because of his attention. His hands groping her breasts in the morning while Leah's brushing her teeth have made them perky, full and tender. His hips thrusting into her as made them wider to accommodate his body and keep her body ready for his attack at any moment. Her pussy lips are always wet in anticipation of when he'll walk by and suddenly either bend or over or kneel before her to bury his tongue in between the folds. Leah's body had grown into a memorial of his desire, lust and want of her.

Taking his cock into his hand, Seth begins to stroke himself as his eyes drink in Leah's body. He's so hard for her right now that it's painful, the slit is glistening with his pre-cum and his balls feel so heavy as they sit waiting for the moment when they can tighten and release their precious cargo.

Seth feels a sense of power and control inside of him as Leah's eyes settle on his throbbing cock. The way she licks her lips signaling to him how badly she wants him – possibly to taste him on her tongue first before letting him fill her pussy with his seed. He watches as her breathing becomes shallower and he looks, carefully enough, he can see her pussy quivering for him.

An idea crosses Seth's mind as he wants to hold onto this sense of being in control, making his sister react based upon his actions and words. Placing a hand on Leah's knee, he slowly pushes her knee up until its bent and resting just a bit below her breast. Her pussy exposed to him fully now at this new angle. They both lick their full, plump lips in anticipation of what is getting ready to happen next. Seth is certain that Leah is expecting him to either slide at least two of his fingers deep inside of her or lick her slow and hard from the bottom of her pussy to her clit. Seth bites his bottom lip, letting out a dark chuckle as he releases his cock and his hand hovers over Leah's pussy. He can feel the heat radiating out and as he quickly glances up at her face, he notices her eyes darkening.

SLAP!

Leah gasps as a cry catches in her throat at the sensation of Seth slapping her pussy. The mixture of both pain and pleasure catches her completely off guard.

SLAP!

Seth brings his hand down again and his smile grows as Leah cries out this time. His hand is wet already with just two quick slaps. Leah hisses as the pain subsides and is replaced with pure pleasure as Seth teases her clit.

"You like that?" Seth asks raising an eyebrow. He bites back a smile as Leah moans deeply while nodding her head as he rubs circles against her tiny bud.

SLAP!

"Answer me." Seth growls out and feels his cock twitch as Leah cries out in pain.

"Yes! I loved it – I loved it Seth." Leah cries out her voice taking on that slightly deeper tone whenever she's turned on.

"Tell me how it felt." Seth states.

"It – it was hot," Leah pants out trying to answer her brother's questions. "There was pain but the – the way you hit my clit," Leah moans out as Seth slides a finger into her. She's doing a good job answering his questions. "It felt so good." She rasps out as Seth wiggles his finger deep inside of her.

"Good," Seth says with a nod. "Now tell me how this feels." Seth says as he slides his finger out of Leah's pussy and quickly places her hand over her own pussy.

Seth smirks as Leah looks up at him questioningly. He's going to tell her how to pleasure herself and he wants to hear all about it. Sure his cock is aching to take place of Leah's fingers, plunging deep into her, thrusting into her sweet spot, drilling into her until he hits gold and feels her juices squirting out all around before he finally adds his on final tribute to the game. It's just that right now the idea of watching Leah masturbate for him is something that he can't wait for anymore. He's heard her masturbating in her room real late at night when she thinks everyone's asleep. He wants her to pleasure herself to the thoughts of him, to make sure that next time she touches herself whether in her room, in the shower or during a break that he'll fill her fantasy.

"Masturbate for me." Seth orders as pulls Leah's leg down and spread her legs wide for her.

Seth looks up at Leah to see the excitement in her eyes but he quickly turns his attention back to her pussy since that is where the real show is going to be taking place.

"Do it, Lee. Show me how you touch yourself at night when you're all alone and aching for me." Seth says as his hand overlaps Leah's and moves her hand slowly.

Leah moans at the feeling of her hand and Seth's running along her lips. Biting her lips she breathes a soft 'okay' and begins playing with her clit.

"Does that feel good?" Seth asks watching amused as Leah's back arches.

"Yes," Leah moans out.

"Good, now I want you to slide two fingers into that wet pussy of yours." Seth says running his hands up and down Leah's thighs. He can't help but moan himself as Leah quickly follows his orders. Her fingers slide in slowly into her pussy, teasing her opening before coming out and sliding down deeper.

"I bet that feels so fucking good, doesn't it?" Seth asks licking his lips and grabbing hold of his dick.

"Yes, it feels so good." Leah pants out sliding her fingers in and out.

"Add another." Seth orders as he strokes himself. Leah does as she's told adding another finger and a moan escapes her again. "Shit," Seth hisses as he can hear the slicking sound of Leah's fingers pleasuring herself.

"Are you tight? I bet you're so fucking tight right now." Seth growls out as Leah begins to pick up speed and he follows her motions.

"I'm not big as you are, Sethy." Leah coos looking down at Seth under her half-closed eyes.

"Tease your clit with your thumb." Seth says as his eyes narrow. He knows that Leah is right because her fingers are stretching her lips but they're not filling her up like he does.

"Oh Seth," Leah moans, her body trembling as her thumb brushes over her own clit.

"I'm here, Lee. I'm here – watching you." Seth groans out huskily. "I'm watching you touch yourself, slide your fingers into that hot, wet pussy."

"I'm so wet, Seth." Leah gasps out as she feels how wet her fingers are getting. Her free hand moves up and begins to tease and tug on her hardened nipple.

"Yea, I can see that. You've not even cum yet but your juices are running down towards your ass." Seth says biting his bottom lip hard. "God you're so beautiful." Seth hisses out as he reaches down and plays with his own balls. "Do you think about me when you touch yourself like this?"

"Yes, oh gawd, yes Seth." Leah moans as her fingers work desperately to help her find her release.

"Do you want me, sis?" Seth asks as he quickly moves to his knees, his hand still pumping on his cock.

"Yes, I want you, Seth." Leah moans out as her hand leaves her breast and wraps around Seth's neck.

"You want me to cum inside of you? You want me to bury my cock inside of you?" Seth asks in between pants as he lowers his hips.

"I need you inside of me, Seth. Fuck me, Seth. Please," Leah begs as she pulls her fingers out of her pussy and wraps her hot, wet fingers around his cock.

Seth lets out a deep growl as his face falls into Leah's hair and he lets her lead him to her opening. She's tight, as always, and so wet. Reaching down Seth grabs Leah's wrists and quickly pins them above her head. He picks up a strong rhythm and watches with a lustful gaze as Leah's breasts bounce up and down before him from his motions.

He can hear the sound of their skin slapping together, Leah's breasts bouncing, her soft moans, gasps and whispering of his name over and over. He can feel her warmth surrounding him, her pussy tightening around him, his balls tightening as he nears his release.

"Oh Leah," Seth breathes out as he struggles to hold out just a bit longer – long enough to feel Leah clench around, feel her choking his cock.

"Leah, Leah," Seth calls her name over and over again.

BOOOOMMMM!

Seth suddenly sits up, his heart racing and his mind swirling and swimming. Laying back down he begins to curse.

"Fuck," He growls out as he throws his arm over his eyes.

A dream – it was all a fucking dream.

Seth removes his eyes as he sees a flashing blue-white light outside his window. He can hear the thunder rumbling in exactly seven seconds after the lightning flash has ended. Taking in a deep breath he sits up but curses again once as he realizes that he has a boner. Letting out a heavy puff of air Seth lays back as he listens to the thunderstorm outside, the house shaking with the force of the storm. Once upon a time he used to be afraid of thunderstorms and always ran to Leah's room, snuggling up close to her, burying his face into her body trying to block out the noise.

His cock twitches at the idea of burying his face into Leah's body now and with a smirk he gets up out of bed.

Leah will help me get through this storm. Seth thinks to himself as he opens his door and heads down the hall towards his sister's room.
