So, today there was a fatal mistake or fatal accident that led us to something absolutely delightful. You and I were left alone together while your parents were out. And we're adults, it's happened to us hundreds of times. But this time you let your hands, your fantasies, your perversions. You started groping my legs, which shocked me. But the way your cock tensed at that moment relaxed me and turned me on. I left all prejudices and our family connection behind to fuck you good. We didn't have much time, but we did more than we expected.
