Last month, my sister came home to visit for the holidays. It’s been just me and my parents at the house since August- this was her first semester away at college, so having her back home was nice. We drank eggnog, made a fire in the fireplace, and shared laughs around the Christmas tree. It was really a magical holiday season.

My sister is hot as fuck. Her and I have always had a little bit of sexual tension- maybe it was just in my head, but growing up we were always super competitive and used to butt heads over all kinds of stuff, and I always felt like we were just one provocative comment away from something happening.

A few days ago, my mom and dad left the house for a few hours to go visit some family friends- my sister and I stayed home and my parents said they would be back later that night. So it was just me and my sister, alone, all day, in our PJs, hanging out and bantering like we do. She was wearing a loose t-shirt, pajama pants, and these little fluffy Christmas socks our mom had bought her, and she invited me to put together a puzzle with her in the living room. I was horny as fuck and I knew it was now or never, so I decided it was finally time to put the moves on my sister- but first, I knew she had to be convinced that incest was morally permissible. I smiled, knowing that with the supreme arguments of my favorite streamer Destiny on my side, I would be unstoppable.

I asked her if she minded if I put on a video in the background, and she said sure. So I started to look up the Destiny incest debate on the living room TV. “Incest debate...?” She looked at me quizzically. “Ha ha, y-yeah, it’s a pretty good example of why our... um... moral intuitions often like, don’t stand up to ethical scrutiny,” I stammered, wiping the sweat from my brow, quickly trying to type in Destiny’s name in the search bar and hit enter. I started playing the video as she dumped the puzzle out of the box and we started to piece it together. Being alone with my sister was already making me rock hard, but with Destiny on the TV, his lighting fast voice already owning the stupid normie who dared to debate him, I was nearly about to fire off a splooge harpoon in my pants. We put the puzzle together without talking, only listening to the video. As it went on, her look changed from surprised, to confused, to flustered. I could tell she was really absorbing it. She was staring at a puzzle piece in her hand, rotating it around between her fingers, when she finally broke the silence. “So... what is with this Destiny guy?” she asked, not looking away from the puzzle piece. “Why is he trying to argue in defense of incest? Isn’t that kinda fucked up? I mean,” she shot a glance at me, then returned to analyzing the puzzle piece in her hands. “Incest is wrong,” she finished. It sounded like she was trying to convince herself just as much as she was trying to convince me. I cleared my throat. “Well,” I started, “it’s actually very difficult to formulate a sound ethical argument against incest itself. You can make tangential arguments against the morality of possible side effects that incest may have, but these arguments have nothing to do with the incestuous act itself being wrong.” Yes, I thought to myself. A solid and concise argument. Destiny would be proud. And that’s all it took- my sister and I locked eyes for a moment, then she lunged for me and started making out with me, hard. “Anon,” she said in between gasps, “I’ve wanted to fuck you since I was in high school.” She started tearing my shirt off of me. “The only thing stopping me was that I thought it violated my axiomatic moral framework. After watching this Destiny video, I realize it doesn’t.” “Really??” I asked her. This was all happening so fast, I didn’t have time to process it. “He’s right,” she continued frantically, sliding my pants down around my ankles. “With the vast majority of axioms people base their moral systems on, incest does not actually violate any of them. Any unintended consequences that come from incest are not actually inherent to the act of incest itself, and can all be avoided with the proper precautions!” she exclaimed. With that, she started going down on me, and I leaned back and smiled up at the still-playing Destiny video, knowing I owed this all to my hero, Steven Kenneth Bonnell II. I knew all along that having the ins and outs of his arguments memorized would one day result in me having real-life intercourse with my sister. That day, I had the best sex of my life. The best part is, no one ever found out, she didn’t get pregnant, and it didn’t tear our nuclear family apart. No unintended moral consequences- just pure, sweet incest.

Thank you, Destiny. And thank you d.gg community for always being there for me. I owe this to all of you.
