The events which triggered my question took place more than forty years ago.
I had been dating Maria for some time. She was a very smart languages student. Blonde with long hair, crystal blue eyes, I found her very attractive even though she was a bit skinny. We had developped a wonderfull friendship, watching movies, exchanging books, visiting exhibitions, going places and talking for hours, dicovering more and more points of commun interest, but sex was out of thé question as I was too shy to ask her to have sex
Eventually, on a saturday nicht, at her place, I grabed my courage and just said to her: ''Maria, I want to make love to you''.
First she seemed shocked . She was happy I had eventually declared to her, but was afraid sex would ruin our friendship, but she finally accepted the idea to have sex. She said: ''OK, you want to fuck, then take off your clothes, I want to see you naked''. I was a bit surprised and asked: ''And what about you ? Will you take off your clothes ?''.''Later, she said, you are handsome and you know I am ugly''. She insisted: '' I am as flat as a pancake and I have a ten years old boy ass''.
I protested: ''To me, you are the most beautifull girl on earth''. ''Stop kiding, she said, and get naked''. I obeid her and took off my clothes, all my clothes. I had an erection and was afraid it
would shock her, it did not. She grabed my penis and started. caressing it. Then, still fully chothed, she took me in her arms and we had the most sensual kiss. She then started to play with my erect nipples, and after a few moments, she left me, naked in the middle of her living room, to go to another room, telling me: ''I have something for you, I am sure you will like it. I was hoping she would come back naked or in some kind of lingerie .
She did not. She came back, still fully clothed, with a kind of bag from which she produced a stethoscope, saying: '' I stole this from my sister, she is a médical doctor''. And then she started stething me, first the heart, then the lungs. The soft touch of her fingers on my chest was quite excîting and she soon confessed: ''Don't worry, I know nothing about cardiology, so if you have a problem, I won't be able to tell''. At one moment, she handed me the earphones of the device and let me hear my heart and I must say it was facinating. After a few minutes of stething, she issued a blood pressure caff from her bag and mesured my BP, she said she had learned from her sister how to do it. After that, she asked me to stand in front of her sitting and she palpated my penis and testes, like a doctor would have done. She then asked me to turn around. She parted my buttchecks and suddently. I realised a thermometer was being inserted into my rectum. Then, my whole body started quakering. ''Dont panic, she said, I just take your temperature'' She did not know that I used to masturbate with a thermometer in my ass, often fantasying about herself, and this was really too much for me. As she played with the instrument, letting it go in and out, turning and twisting it, as if the thermometer was making love to my ass, I was afraid I was going to jerk off on the floor. It did not happen. Maria eventually took out the thermometer. My girlfriend did not indicate what my temperature was, but, with a big smile, she told me: ''Now you can undress me''.
The sex we had then was just fantastic.
