Has an ex who trained me to take a strap on cock up my ass. It was awesome.
She broke me in slowly. At first she would lick my asshole (a first for me). Who wouldn't love that sensation?
Over time she would gently put a finger in my butt after licking my asshole. At first I tried to say, "No thanks, that's not for me." But she was insistent. She would say things like: "You never had your butt licked before, and you liked it, right? So just try a finger. Everyone knows it feels good."
After several months, getting my butt fingered just became part of regular sex play. Before making love, I just knew I was going to get my butt fingered for a while, and that I was going to get rock hard. She was training me to associate getting fucked up the ass with sex.
The next step was, she asked me to get on my hands and knees to take the finger. While it was happening, she would say things like "You like getting fucked up the ass, don't you?" And If I didn't say "Yes" she would stop. I wanted to get to fucking her pussy, so I learned to agree with whatever she said.
Well, you know where this is going. She really wanted to see me get fucked by "a real man" and "a big black cock." I would have to say things like "can you please fuck my faggot ass" and that is how we would initiate love making.
I learned what phases turned her on. "I wish this was a real cock fucking my asshole." And she would want me to describe a big muscular guy fuckign my butt. By the time it was time to put it in her, she would be soaking wet.
Finally, once while on vacation, she suggested we go to to a sex store together. She made me pick out a strap-on. I remember the gay worker in the store saying, "Oh, these are my favorite types of couples! Just need a little help to bring the guy out of the closet." I had never felt more humiliated in my life. I remember him saying something like: "Get him used to this honey, and he will be begging for the real thing in no time."
My wife's reply? "Oh, he already does." They shared a good laugh. She wanted me to get the guy's number but I wouldn't do it.
Shortly after, I found out my wife had been fucking someone on the side for over a year, and she was in love with him. She left me high and dry, and even took the strap on.
Vanilla sex just doesn't do it for me anymore. Now I always think about a big black guy fuckign me up the ass, in order to cum.
