My girlfriend and I had always enjoyed anal play, being it with fingers or with toys, both of us occasionally penetrated the other and we had become accustomed to it, specially to vary our routine.
After my 42nd birthday, my doctor recommended I have a prostate check-up and because it seemed the normal thing to do, I did.
I made an appointment with an urologist in a different clinic and on the day, my girlfriend surprised me saying she would like to go with. That wasn't a problem for me and I agreed easily.
Now let me tell you a little about her. She is a hot plump girl, in her mid thirties, very large boobs and I would call her a sex addict due to her appetite. She normally goes out in tight short skirts, tops with a lot of cleavage showing, loves to use high thin heels and sexy lingerie. Needless to say, she gets a lot of attention on a daily basis and always shares her experiences with me.
On this day, she looked particularly hot. She wore a very short and tight black skirt, a short white buttoned shirt with the top buttons opened to show off her priceless boobs, no bra, black see through stockings with one of her many garter belts and high black stiletto heels. She had her nails done bright pink and wore a pink lipstick which made her lips full and succulent. Just looking at her made my cock twitch in my pants and I couldn't wait to get home to have sex with her. And she knew it.
We went to the doctor, I admit I was a little nervous but she kept telling me it shouldn't be any different than when she fingers my ass. Needless to say, that just made me hornier.
When my turn came, we entered and the nurse told us to sit down, saying the doctor would be in in a moment, and left. My girlfriend told me she was getting horny and I told her to behave herself but that after the appointment I would take care of her.
In came the doctor and immediately I noticed his eyes looking at her discretely up and down, focusing on her boobs. Her eyes lit up and I could see that she found him attractive. To me he looked like a normal man and by the name I guessed he must be Italian or Greek. He had dark hair, beard stubble, he was about 6 foot 2 and with a very large frame. You could tell he worked out and was in shape. I guessed him to be about 48 years old.
He asked me a bunch of questions about my habits, if I sit all day, if I urinate normally, etc. Then he took me into the other room where he told me to take my pants down and kneel on a low bed that reminded me of a massage bed. He pulled a chair and sat behind me and I heard him slapping on the rubber gloves while telling me to relax. He said it wouldn't hurt and for me to just stay like that on all fours.
