I was so horny that I took out my sex doll and fucked her thoroughly. My lube ran out so I quickly got myself a new one. I came again and continued fucking my sex doll. She made me really horny and was so nice and warm and somehow felt so real. Then I noticed that my step-sister had simply swapped places with the sex doll. That made me really horny, otherwise she almost always only wants to fuck with a condom and I've just been inside her without one. We were both so horny and she suggested that I just keep fucking her, so she first gave me a good blowjob and I took her missionary. To top it all off, I also jerked her off.
