Winning The Genetic Lottery

James would walk into his apartment following an early shift at the office building that he worked at. He was lucky, as the snow started coming down the second he clocked out of work. At the moment it was coming down slowly, yet it was supposed to turn into a full blown blizzard later on, highlighted by subzero temperatures and icy snow. Only one thing was left for him to do today, that being receiving the last boxes of his things that his step-sister, Alina, would be bringing him soon. He just hoped that the snow wouldn’t delay her. Soon after this thought he could hear her car pull into his driveway. He would then rush out to assist her with bringing in the boxes. Immediately when he went out he felt the cold, with the snow having picked up significantly since he was last outside. He nodded hello to Alina, who at the moment was bundled up significantly, before bring boxes inside. They finished relatively quickly, but not quick enough as the snow picked up to an unbearable level. They would both go up to his apartment, hoping to wait for a break in the snow. They would take off their jackets as they got inside, now allowing him a better look at his step-sister. She had grown significantly since he left for college, in all the right places as well. Her average height at 5’5″, still nothing compared to his 6’3″, allowed for a gorgeous build, with her huge, tight ass and double D tits forming a nice hourglass figure. Facially she was also gorgeous, her long blonde hair and large red lips being the most notable things. He himself was also very good looking, having attracted much attention from women throughout his schooling. This was complemented more by his massive cock, hanging at 10 inches long with the girth close to the width of a soda can. Whenever she moved he couldn’t help watching her ass sway. Soon she would speak up, forcing him to briefly stop looking as she said, “Well. This trip is already taking longer than expected. I guess I may be here at least until morning…”

This didn’t seem like bad news to him, though it may to her. He at least tried to comfort her by saying, “Well, we’ll make the most of it. I’ll get started on dinner if you want. I should have something around here that I can make.” He would start to look around when he said this, searching through he cabinets, before saying. “I think pasta is the best I’ll be able to do though.”

“That’s perfectly fine.” She would reply with. “I’m not one to judge. I am the one who got herself stranded here so.” A laugh would escape her after that, before she would look around the small kitchen/dining room. “Mind if I go watch some tv while I wait?”

“Of course not.” He said in reply. “Everything that’s mine feel free to use.”

She smiled a gave him a hug and a seemingly innocent kiss on the cheek before whispering, “It’s nice to see you again bro.”

“You too sis.” He replied with, hugging her back.

 

*LATER ON THAT DAY*

“Thanks for the dinner.” Alina would say, smiling at him as she stood up. “Let me at least load up the dishwasher to slightly make it up to you.”

Jason would laugh, saying, “It’s really not a problem. But I would turn down your offer.”

“Great!” She said, taking his plate and walking over the the dishwasher, and placing the plates inside. “It’s really nice getting to talk to you in person again. You’ve changed a lot for the better since I saw you last.”

He would laugh, replying with, “Yeah. That’s for certain. I can say the same about you.” Watching her again would start to get to him, as a boner started growing underneath his jeans. Meanwhile, she would fiddle with the dishwasher for a while before looking back at him.

“Hey, this is sorta embarrassing… But how do you start this thing?” She said, laughing as she did. He would laugh as well before walking over and, not realizing until it already happened, he pressed his boner up against her ass as he reached over her and started the washer. She reacted soon after it happened, saying, “Thank- huh? What is that?” Before reaching back and grabbing his crotch with her hand. Realizing she quickly jerked her hand back and shouted, “Oh my god! I am so so sorry… I… Uh. I should probably go shower.” She would quickly walk to the bathroom after this, leaving him to contemplate what just happened. He was embarrassed of course, but a part of him couldn’t help but to be excited.

He would let some time pass as she started her shower, before knocking on the bathroom door, saying “Hey Alina, I gotta come in and use the bathroom real quickly.”

“Alright. That’s fine.” She said back, clearly occupied with her shower.

His bathroom was larger than normal for a medium sized apartment like his, with a larger than normal shower. When he entered he was able to see her entire body clearly, as the glass hadn’t fogged up yet. Her ass was enough to get him close to a boner again as he walked over to the toilet and took out his cock, at the moment being at a solid 8 inches, and starting pissing, occasionally sneaking glances at his step-sister in the shower. She would be unable to stop herself from glancing as well, as she let out a small gasp when she saw the size of his cock. With her pussy getting wetter by the second, she couldn’t help but to move a hand down to it as she kept stealing glances at him. Soon he would finish though, and would wash his hands before starting towards the exit. She made her decision the act at this moment by saying, “Hey! Could you do me a favor and wash my back?”

Trying not to sound over eager he would look at her, and say, “Umm… Yeah. Sure!”

“Awesome!” She replied with, glad that it didn’t go badly. “Strip down and hop into the shower so you can help me.”

He wouldn’t mind her taking charge, as he would strip down and climb into the shower with her, taking some soap and starting to rub it on her back. She would moan as he did, clearly wet just off the thought of him. He saw this as his moment, as he allowed his cock to move freely, rubbing against her ass as he rubbed her back. “Right here?”

She would moan slightly louder now, “Yeah. Tha-that’s it.”

He would keep rubbing on her back as he now took his opportunity and positioned himself, before pushing his member into her soaking pussy. She let out a loud moan when he did, also placing a hand on the glass of the shower as he slowly pushed in and out of her. Soon he would start picking up the pace, now pushing his full 10 inches into her as he fucked her.

“Uhhnnn you’re so big! Ah… Holy fuck…” She said, still moaning in ecstasy as he reached around and grabbed a tit with his left hand, using his right to stabilize her waist. Her own arms weren’t strong enough keep her stable against the shower glass as now her right tit was pushed up against the glass. He also moved her leg so now it was over his arm as he started fucking her from the side. His strokes were long and deep as he let out some moans as well, with precum now flooding from his tip. Her ass and tits shook with every thrust, rippling for seconds following. She was also practically moan-yelling in joy now, likely audible to his neighbors. He continued pounding her, occasionally slapping her ass to see even more jiggles than normal. He started approaching his climax soon, and then turn he into a doggy position, before starting to fuck her again clearly enjoying the view. She clearly was enjoying it as well as she moaned, “Ahh fuck yeah bro. Oh god you’re amazing.” Her ass continued jiggling as he took her from behind now, her pussy tight around his cock though likely due to the shear size. They continued like this for a while, as he now used her tits instead of her waist to tightly grab as he relentlessly pounded her. Finally he would flip her around into missionary and hey would fall to the shower floor. Not caring though he continued fucking her as she screamed, “Oh fuck, oh fuck! I’m cumming!” With that she would squirt her juices onto his cock, and her pussy tightened around it. This would be enough to send him over the edge as well, as he wouldn’t bother pulling out as he pumped her full of his warm seed. He continued cumming as he pulled out of her, shooting some of his load onto her stomach. They stayed in that position for a while, looking at eat other, before Alina took some of his cum that wasn’t washed away by the shower and took it into her mouth, clearly savoring the taste. She would also break the silence saying, “Don’t worry. I’m on the pill. Thanks for checking first though.” She would giggle before continuing on. “We should probably actually use the shower now though.” She gave him a long kiss on the lips before turning back to the shower head and starting to clean herself off.
