I Banged My Filthy MILF Sister And With The Fuck Machine Too

My horny sister came to me the other day and told me she got a package. I was like what did you get now? She told me she got a fuck machine. I couldn’t believe what she was telling me. I asked her what made her buy that? She replied “I want to suck your dick while I’m getting fucked by the fuck machine.” I didn’t know what to say. She’s like, don’t act like you haven’t tried to look at me in the shower or when I’m changing. I started to sweat cause I didn’t know she saw me. I told her I was sorry about that but she didn’t want apologies. She wanted me to go set up the machine and get rock hard for her. I was so shocked but turned on also. I ran to the room and set up the fuck machine as fast as I could. Once I was ready I told her we are good to go. Her and I walked into the room and started what was the best day of my life. I have the best sister!
