I'm into the bro/sis thing big time. When I was young I fucked my younger sister many times. After I got married I moved from Ohio to Florida and rarely saw my sis for many years. After my sis had gone through a difficult divorce and had beaten a bout with cancer, I visited her and after all these years, I fucked her again. Damn did I ever enjoy that. I was in my early 60s and she was in her late 50s. My sis is still the best fuck I ever had and boy can she suck cock better than my wife. My sis is now remarried (happily) and I sure would love to fuck her again.
