From friends to lovers…to siblings

Tiffany and I had been friends for a while, when we reconnected after about 15 years. Our families have always been close friends, but she and I weren't really close.

About 7 years ago, after not seeing each other for about 15 years, we ran into each other at a party and got reacquainted. We soon started hanging out and became good friends. Since we'd first lost touch, we had both gotten married and had families of our own. We started getting our families together and doing things like going on camping trips. Things were going well, until 3 years ago when everything changed.

3 years ago, when I was in my late 30's, I found out that my dad wasn't my biological father. We found out that my mother had an affair with her father and that we were actually siblings. Most people, after the initial shock, would be excited to find out that not only did they have another sibling, but it was someone with whom they had grown close. When we found out though, Tiffany couldn't stand the sight of me and told me she didn't want to see me ever again. What happened? Well, it all started about 2 years after we reconnected. We started fucking. Every chance we got.

My name is John. I'm 41 now. I'm still married to my wife Jean and she doesn't know a thing about what Tiff and I were up to. Neither does Tiffany's husband.

Five years ago, my company sent me to a convention in Las Vegas. It just so happened that we are both in the same field and her company sent her there as well. We loved ...

... this, as it meant we wouldn't have to try to pass the time with people we didn't know well and could hang out.

The conference was 4 days and we decided to fly in the day before and fly out the day after. We got in and went straight to our hotel to check into our separate rooms and drop our stuff off before exploring. It was pretty uneventful, we walked around, chatted, grabbed dinner and then did a little gambling before going back to our rooms for the night. I got back to my room and decided I needed to relieve some tension, so I watched some porn on my phone and jerked off. Around midnight, as I was almost asleep, my phone buzzed. I took it out and saw that Tiff had sent me a message, just a silly meme that made me laugh hard. I said goodnight and fell asleep, with the last thing I thought about being her sending me that picture.

The next day I woke up early and got ready for the conference. I texted her and she didn't reply, so I decided to go to her room. I knocked on the door and she answered in her underwear, with a toothbrush in her mouth. My heart skipped a beat.

"Shit, I'm sorry, I slept in" she slurred through her toothpaste filled mouth.

I have to say, for being a morning mess, she was beautiful. I had never noticed it before. I went in and shut the door behind me. She went to the sink to continue brushing and when she bent over to spit, I noticed how perfect her ass was in her underwear. Nice and round, perfect toned legs and a tight abdomen. My dick ...
