A/N: Hi everyone. Story creator here. Two things I wanted to point out. First of all, I'm considering "gamifying" the story and sort of testing certain things out with the feature as I've never really tried it before. So, bear with me on that front. Secondly, I just want to throw it out, to be sure it's clear. I'm totally cool with people adding chapters of your own. So if the feeling bites, feel free to add chapters. Thanks! ~ 12/24/2020

At twenty-one, masturbating was no new venture for Ryan. Neither was jerking off to his target. Before him, on his laptop, a picture of a bikini clad twenty-two year old with red hair meeting her shoulders showed before him. The woman in question? His older sister Dana, who he had jerked off to since he was 14. It had all started at her birthday party where his friends egged him about having such a hot sister. That night, their words fresh on his mind, Ryan gave in and jerked off to Dana for the first time. Initially, it was merely something to do. Something he enjoyed.

Over time, he realized...he wanted more than just a fantasy. He really wanted to fuck his sister. Over the past few years, a new fantasy developed.

He wanted to be the one who got his sister pregnant. The idea of his sister, her belly tight, with his baby turned him on more than anything ever had. Frankly, it was a fantasy he no longer wanted to resist. He wanted his sister pregnant.

At the very least, he just wanted his sister.

The only question he could never figure out was how. Fortunately, the motions were setting. Their parents gone for the week, he had full free time to figure out how and wait for the proper time.

Finishing into a tissue, Ryan disposed of it and exited the the close-up picture of his sister.

Walking into the living room, Dana was already waiting for him on the couch. She sat Indian styled wearing flip flops, blue jean shorts, and a bikini top. Ryan gulped and sat down beside her.

"I was wondering if you were going to leave me out here all by my lonesome," Dana said. She began biting her nail.

"No, I was just...busy. Been waiting long?"

Dana shook her head. "No, I just walked in a few minutes ago. Mom and Dad already gone?" Ryan confirmed it. Dana smiled. "Well, hey. Looks like we have a whole week together to just ourselves then! This will be nice. Catch up with my little brother." She playfully wrapped her arm around his neck and patted his shoulder.

"It'll be great!" Ryan said. Even better if things work out, he thought. He couldn't believe he was actually going to go through with it. To seduce his big sister. This had the opportunity to either be the best week of his life, or if it went wrong, the worst.

Nothing worth it was ever easy, as it went.

"So, anything you'd like to do tonight?" Dana asked. "Just hang out at home tonight? A bar? Either is great for me, but I'm opened to suggestions."
