It had been three days since you fucked me in any hole, let alone my proper sex-hole, and I was starting to lose my mind. Usually, I could count on you fucking my ass anywhere from once to a dozen times a day, depending on your schedule (and my choice of lingerie). And yet, it had been three days.
You had trained me to be your good anal-only slut, trained me to understand that my ass was my real, proper sex hole, while my pussy was only good for providing lube. I knew that Daddy's cock belonged in my ass, and that he owned my ass. We always loved to ignore my jealous, worthless cunt as it drooled all over everything. Good anal sluts never, ever touch their dumb little pussies. I had always loved anal, loved the stretch and the fullness, the ability to take so much more than my pussy ever could, and loved how it hit that spot juuust right.
You had trained me at first to take the relentless anal fucking, just for Daddy, and then I had learned to love it, and then to need it. By now I was so well trained that if I hadn't had your cock balls deep in my asshole by at least once by 6pm, I was so horny that I couldn't think straight. Not to mention that without being used by you I felt... Useless. Unloved. Empty. (The latter partly due to the fact that you loved to fill my ass with a big load of daddycum and then insert a plug, keeping me filled up with your seed all day long, reminding me who my hole belonged to every single minute).
