“Sorry, Pen,” I answered earnestly as she really did look annoyed.After an hour in which she went over what her daughter, Kirsty, wanted for her b...irthday Penny left to pick up her youngest from school, which left me at home alone again and some peace. We do get on, Penny and I, but I also like my peace. But I did feel ashamed at how I’d put my own step-sister down about her going away with me. But really, why would I want to go on holiday with my own step-sister anyway? The main point of going. “You want to see what you look like in my pussy in this position?” she asked, clicking a picture of our crotches.Her phone flashed, and a second later she showed me the picture. My cock throbbed in her when I saw it. I loved the way her pussy looked with my cock stretching her open. “So, anyway, the other night. Can I tell you something I’ve never told anyone else?” she asked.“Haven’t you done that already?” I asked, holding her hand so I could still look at the picture.“yeah, a few times now.. "You will not stop thinking about me and how much you want me to fuck you in all three holes and drink every last drop of my cum" Josh whispered to Kara and then turned off the device and said goodbye to everyone.In a daze Kara thought to herself what the fuck just happened I swear I just was talking to Josh not standing in the staff room... but hey Josh I would definitely fuck him. Kara shook her head thinking I've never once thought that I must just be horny today and sat down back at her. I didn’t think twice about it as we drove home and I commented on how beautiful she looked especially in her short skirt showing off those pretty legs. I reached over to squeeze her thigh and pushing up inside her skirt I noticed she wasn’t wearing her thong that she paraded and teased me in all morning getting ready for work. I couldn’t be more pleased that she was naked underneath and began exploring my wife’s pussy with enthusiasm. While raising one of her legs up in the seat she quickly ran.
