When I was around 18/19 I first discovered on a visit to my Aunt Grace, (actually my great Aunt) that she still had a large sex drive, she was a bit tearful and she opened up about the loss of her last male friend who, as she told me, used to take part in oral sex visits. What if I help you out, Aunt, I could do for you whatever you want! - 'What would your mother think?' she said. Oh never mind her, I fuck HER about 2 times a week! - 'Ok' she replied. I got my cock out and she happily sucked on it. 'Put it inside me now, son' I fucked her, slowly at first, until she told me to fuck her harder! 'I'm quite slack there, my bboy she said, give it to me hard!' It may have been taboo, but it was fantastic!
