This was really odd but very exciting at the same time. My wife invited my niece and her boyfriend to have dinner at our house what none of them knows is that I've been having sex with my niece for about 6 months. I was a bit shocked when my wife told me she invited them but things went pretty well, at least until we started drink after dinner. Around midnight after a lot of talk and drinking my wife fell asleep on the sofa and my niece's boyfriend was upstairs playing Fortnite with our son. I told my niece to go to the bathroom downstairs and wait for me. This was what happen then.
