Though no human ear would have been able to clearly determine what he actually said.He woke up 90 minutes later with the alarm and slugged to the show...r.He went about his day at work with the usual. There were a couple more meetings than usual today, but it wasn’t bad. He took time every now and then to check his Grindr app. Since Katherine was away, he would take the opportunity to get some boipussy. He messaged back and forth with a few potential candidates, but he knew folks were subject to. There was drinking, there was music, and there was a big bonfire. I paid the girl five dollars for my plastic cup. That bought me all of the beer that I could drink before the keg ran out.One of the boys told me that there was a girl over on the couch that was letting everyone fuck her. I looked over to where he had pointed and saw the couch but it was turned around facing the other way. I did see a head bob up a few times. When he stood up and came around the end of the couch he was zipping up. I finger myself to the same pace that daddy's cock fills my sisters hole as he slams into her. Soaking the front of my panties from my arousal in the process. As he bottoms out in her one last time I hear him grunt as he orgasms, holding my sister tight to his body as she moans like a whore."That was amazing daddy, I love you so much" They kiss as he embraces her one last time for the night. With their lust temporarily sated she turns and starts to make her way to her own bed, her body flushed. I grinned at her, sharing how much I had enjoyed the whole charade.We all settled down a bit and Kathy asked if we all wanted to go up to her room and hang out a while? I said, sure, doing my best to sound low key and casual, but I don't think I fooled either one of them. Johanna nodded agreement, and I think she was very much okay with having me join them. So we left the table and Kathy took my hand in hers and I got Johanna's and we went up the stairs, Kathy leading me and me pulling Johanna.
