She's fine, no need to risk everything

"Maybe we should wait a little bit, see if the fogginess goes away on its own," I said.

"Uh, okay," Cassidy said. She thought it over herself but I think she trusted me, or at least, didn't want to argue with me.

I dressed her on the couch and covered her with a blanket, staying down there for a while. We googled a bit and it seemed like she might be okay, although we read some things that suggested she shouldn't go to sleep any time soon. We played Smash Brothers Melee, another childhood favorite, and she kicked my ass thoroughly.

"I guess your brain's okay," I said, trying to be funny.

"Yeah," she nodded, "The headache's going away."

"We probably shouldn't do that again," I said.

"Yeah," she agreed.

After a few hours she was tired and not feeling any more symptoms so she went to bed. I slept in her room with her to make sure she was okay.

The next Tuesday I got the call that my background investigation was finished and they asked if I still wanted to attend the academy and become a cop. I agreed and went to tell Cassidy. She was a little more subdued than I hoped, but she went out for a celebratory dinner with me.

The next few weeks were very busy as I started my training. I was meeting new people and making new friends. Cassie's stream was getting more and more popular. She played with one of the most popular female streamers and acquitted herself well, getting 1,000 new paid subscribers off that alone. I couldn't begin to keep up as her helper so she hired an outside manager.

I became a cop. She was there to cheer when I got my badge, but we hadn't had sex in a week. We hadn't done any bondage since the incident. I was sad but not surprised when she started looking for an apartment of her own. She said it wasn't because of anything I'd done wrong, but I knew she couldn't trust me. I didn't blame her. I'd almost killed her, then I chose my career over her safety. She had turned out to be fine, but that was just luck.

I didn't deserve her anyway. I loved being a cop, and having sex with my sister, especially the way we did it, clearly wasn't healthy. I didn't try to patch things up sexually or romantically. I let her move out.

She'll always be my sister and best friend, and I think that's all I deserve. I miss what we had, but it just wasn't meant to be.

This is the end of this path. Maybe it's the sad ending, maybe it's the realistic one, the reader is free to decide. I hope you understand why I wrote it even though it's not the ending you might have wanted - the wonderful feature of this site is that the writer can present multiple options like this. The first path I wrote is the one I think more people will pick, but I felt like both should be written out. I might continue the first path (eventually) so leave comments with what you think.

Thanks for reading everybody! I've enjoyed writing this.
