Dear RocketStripe,
I want to tell you this particular event, if you want:
We were on a holiday with our camping trailer at the Baltic sea, my father, my mum and me. It was a nude camp; my parents loved this (me not so much after my puberty had begun...)
One day, I had a cold, and I was in bed in the trailer. My parents were togehter with a couple in the tent infront of the trailer; the wife was a doctor.
I think, I caughed, and she must have heard it. "Oh dear", she said, " your boy is sick. Shall I have a look at him?" After a while, she got her instrument case from their camper nearby. She came into our camper to see me. "Hello, how are you..." She was naked to the waist. She was perhabs 40 yo and had nice round and full breasts. When she bent over my bed, her breasts hang down. She felt my head, told me tom open my mouth etc. Then, she took her stethoscope out of her case. It looked very inpressive. I remember that it was red and had rubber tubings. Much later, I learned that it was a Haselmeier Supraphon. It became my favorite Stethoscope :-) She told me to take off my pyjama jacket. My nipples became hard. I was very much embarrassed. My head must have been totaly red. I can't remember if my cock was already stiff at that moment. She put the Stethoscope into her ears and asked me to take deep breaths. Then, she began to listen to my bare chest. The chestpiece was cold... It was a bell without diaphragm. My heart must have thumped. She listened to my chest, my lungs, then to my heart, then to my back, again breathing deeply. When she listened to my back, and I couldn't see her, I felt my erection, I remember. She listened for quite a while. I remember that I felt her putting her stethoscope from one spot to the next. A feeling which I love since that moment still today :-) I began to enjoy that feeling and emotion. It was a mixture of fear and excitement. On one hand, I wanted that she stopped listening to my lungs; on the other hand, I had the desire that it never ends... "OK", she said, and took me back to reality, "you've got a really bad cold - I'll give you some medicaments..." I pulled my pyjama back on. During the Stethoscope exam, my mother was also in the camper. But this didn't bother me. When both were out again, I felt my huge erection even harder...
Later, when I saw the lady doctor somewhere, I got hard instantly. Which was very unpleasant when I was naked :-(
