How it happened

When I met her 5 years ago, it was in an incest chat room. I told her that I was into the thought of incest and she told me how she wants her dad. We hit it off right away and I was constantly horny around her because she was a sex addict. She would call me dad a lot during sex and it drove me wild. I asked her once if we could try anal and she did not want to. I figured she wasn’t into that.
One day I was at her dad’s house because I had to let his dog out while he was out of town. I decided to snoop around and actually found his browser history. He didn’t even have a password to log in. His browser history took me to an incest forum where he talked about his daughter and how he fantasizes about her. He talked a lot about her ass. I was mind blown when I came across this and wanted so badly to hook them up. I did not say a word to her about it because I did not want it to happen behind my back. I spent almost a year throwing hints at her dad hoping he would catch on. He would just awkwardly blush and brush it off like i was just speaking nonsense or being inappropriate. After almost a year of what felt like waisting my time with the hints, I finally told him one night after a few drinks that his daughter is sexually attracted to him. He got super nervous and defensive and was trying so hard to act like he found it gross. But I could see right through him. I told him exactly how e we met and his whole demeanor quickly changed. His curiosity was peaked. He began asking a ton of questions. I answered every single one of them. It was getting pretty late that night so I told him, I bet I could hook you both up if you really wanted to. He was like a kid in a candy store. I could see the intense excitement and knew that he was definitely about to masturbate all night. lol. He quickly said, “that would be the best thing to ever happen!” So I told him I would help him out. Literally the next morning, I told her that I had a long conversation with her dad while I was at his place and how he is also sexually attracted to her. She though that I was bullshitting her so I texted him right in front of her to confirm. Instantly I could feel the disconnection between us as her eyes were eagerly set on him. I told her that he had mentioned that if I could talk her into it, that he for sure would do it. She was immediately all for it as well. I arranged going back over to his house immediately as it was a Sunday and we had nothing going on. It was set in stone. We knew what was about to happen. Once we arrived at his place, their behavior around each other seemed a lot more shy than I was expecting. But almost in a sinister way. Almost like they were both trying to get me out of the house. There was no way I was going to miss it. I told them we should of have a few drinks and play cards. I do not think that’s exactly what they wanted to do, but they agreed to it anyways. We played cards and I continued to be the middle man in their flirty behavior by encouraging them to follow through with it if they were going to talk about it. I kept telling them that I’m feeling tired and when I go lay on the couch, then they should just go for it. Finally at about maybe 10ish pm, I did exactly that. I went to the couch and acted like I passed out hard. I was actually wide awake and pretending to sleep. They waited a little bit and I could hear them talking very quietly and heard her chuckle a few times. It wasn’t long after this I heard the talking stop and couldn’t make out what sounds I was hearing at first, but it was her throat making quiet gulping sounds really slowly. I could see through my eye lashes and they kept stopping to check and see if I was awake. I would hear her soft and quick steps to the kitchen opening and see her head peak out. After about three times of them stopping to see if I was awake, they snuck quietly past me and down the hallway and into the basement where there is a spare bedroom way in the back. I made sure to wait until they started up again. Except now she was deepthroating the hell out of him. I could hear the bed bouncing with her momentum. I heard him say a few times, “holy shit Megan!” The door was shut but I could see that they had turned the tv on. I layed flat on my stomach outside the door with part of my legs out of the hallway and into the living room. I could see it all from under the door. I had never been so hard in my entire life. Her yoga pants were pulled down just below her butt and she was devouring his dick. After a bit I heard him ask if she likes butt stuff. She told him yes! I was never able to get her to do that, so that one kind of stung a little bit. But I was way to caught up in the moment. I don’t think I even blinked the entire time and I caught myself holding my breath several times. I watch him get on top of her in the prone bone position and that is when shit got crazy. He fucked her ass like nothing I had ever seen. It was like a medium pace but deep with slow yet powerful thrusts. Like a slow hump with hard pressing. I could see her butt squish up against him with each thrust. He only lasted about 2 minutes and came hard inside her. He rolled off of her and they were both breathing super heavy. They spent a bit catching their breath and then began to whisper things I couldn’t hear. I waited for them to go again, but after laying in the ground for too long my back was killing me. I slowly snuck back upstairs and got back on the couch. I shit you not, not even 15 minutes after going back upstairs, I could hear them starting to go at it again.
Here is another photo of them. I think they took this in Chicago at the navy pier. This picture was most recent
