I have just finished whipping My fetish girl, Lilla Grace, and now I want her arse to suffer on the inside. You see, I am really in the mood to fuck her, but I don’t want her to enjoy it too much. I know she would desperately like Me to fuck her in her vulva, but this is about My pleasure and not hers. No, I am not going to put My big strap-on there; instead, this big cock will go right up her arse. I am going to fuck her butt hard until I am satisfied while she gets hornier and hornier but totally unsatisfied. That was so good; maybe I should lock her in permanent chastity and only fuck her arse from now on.
