My friend Hinatou is a very active libertine who has already fulfilled many of her fantasies. She loves sodomy, but until now only in the "classic version". She's never had an anal fist. I have to say that it's not a very common practice, and you really need to be an anal enthusiast, with experience of sodomy and the desire to have your ass dilated to the max. When I suggested she try it, she was immediately enthusiastic. With a little difficulty at first, and a rather unsuccessful attempt with my fist-shaped dildo, she eventually takes it like a real anal pro. At the end, I give her homework to practice at home, as lesson no. 2 is soon waiting for her!
