My sister-in-law is very perverted and loves sex, the problem she has with my brother (according to what she tells me), is that he finishes very quickly and doesn’t like to use toys. During one of our conversations about this, I told her: “I would really fuck you so good, bitch, for over an hour.” Apparently saying that drove her completely crazy and she immediately approached me and started masturbating me while she kept telling me repeatedly that I was her true man. Nowadays she’s my bitch and I fuck her with my big dick whenever I want.
