My wife's best friend sister

Last weekend (Australia Day long Weekend) my wife and I were on the Gold Coast for my wife's best friends mother 70th. That to means one thing and that is having sex with my wife's best friends sister Michelle. We arrived at the GC Airport on the Friday morning still exhausted from not sleeping to well after the 47 degree day in Adelaide. After posting on social media that we arrived the first like I got was from Michelle. When we settled in at our apartment I got a message from her saying would it be possible at some point over the weekend whether or not we could be alone. I said yes as I knew what we would be getting up to. Friday came and went and I messaged her Saturday morning I would be going for a walk. Michelle lives at Kirra and we were staying at Rainbow Bay, so not too far, but far enough. I notified her when I got close and she sent me her address. when she saw me arrive up the stairs she let me in and quickly. As soon as I was in we went straight to the shower and we stripped our clothing off and she was immediately on her knees and taking my rock hard cock in her mouth and I exploded my first big load of my salty love juices. This had to be quick because it was the day of the party and we didn't want to give any hint we were fucking. As soon as we got out of the shower we went straight to the bedroom and she got on her back, spread her legs and told me to fuck her big time. With Michelle being so wet my cock slid straight to a gasp from Michelle. I then proceeded to thrust away finally cumming in a second explosion filling her hot twat with my seed. After we kissed for a minute we got dressed and I walked back to the apartment feeling satisfied and partied on without any of the other guests knowing what we had done.
