I had an affair once with a man who insisted on anal only if he penetrated me. He said that because I was married and cheating that I would get fucked in the ass and only the ass because that's what married whores deserve. He meant it.

Everything else was fair game, including very rough oral and spanking, but he always fucked me up the ass, often when I was tied up an he always came in me.

He enjoyed tying me up and wanding me until I couldn't stand it any more and I begged him to fuck me only to get fucked in the ass. This was extremely humiliating and frustrating but after a while I craved it.

One of his favorite things to do was to put bondage tape, or sometimes duct tape), over my pussy and rub me and spank/slap my pussy, while he fucked me up the ass. It's hard to describe how humiliating and hot this was and sessions with him caused me terrible shame and guilt. But I always came back for more.
