Special consultation with the sadistic doctor

This story happened when I was 13 years old and still a virgin. My mother had taken me to the general practitioner, just for some tests because my arm hurt playing football in school. But that's only an excuse for doing hundreds of exams...We went to Dr Carla (not her real name) and she showed kindness towards me and my mom. The doctor must be young, about 25 at most. After asking a few questions, he asked Mother to wait next door while she examined me. She held my wounded arm and squeezed it while she said: "Now we are just the two of us"... Without understanding, with a slightly sore arm I smiled. Then she asked me to take off my clothes because she was going to examine me. Thinking that this is professional business, I did what she told me. Never having been a boy whose body was very developed, on the contrary I looked more like a child who at that moment was under the doctor's power. What are you talking about?" She slapped me hard and said in an authoritative tone: "Call me Madam Carla, from now on you belong to me!" Scared I didn't know what to do. It was then that she pulled my hair and made me get down on her knees for her. Then she sat on the patient walkway and lifted up her skirt completely, which climbed easily. So she took off her panties and in a moment it was with its mouth open only for me. Said: "Come here, slave of mine, suck me now". Made disgusting face and plucked my hair. I don't even know why but he liked being subjected to those orders. Knowing that she sent me and I was at her disposal excited me, so I started sucking on Dr. Carla's mouthpiece. She was already wet and began to groan when she felt my tongue penetrate into it. I stuck out as much of my language as I could and kept moving up and down in a motion which made her delirious. When I stopped being tired, she would tell me to keep going. She then said: "Listen my slave, from now on you are only mine and everything I command will be an order!" Feeling like a real program boy to her I replied: "Yes ma'am, I will just obey you"... It was with hard stick when she pushed me against the scales with one hand and squeezed my dick tightly with another. I shouted and gave perverse smile. He seemed to enjoy my inexperience and innocence. Probably he should have known that it is my first relationship and took full advantage of this opportunity. I was enjoying it too, but she was very unpredictable and didn't know until when would hurt me enough to make me run out of that office. She then grabbed a long piece of gauze and tied me down at the foot of her desk. My arms were immobilized. I was dirty and tired and not sure what to do. The doctor bandaged my eyes with another gauze band and disappeared for an instant. I tried to let go but couldn't. Then I felt her presence as she came back by passing something cold on my body. It must have been alcohol or some substance like this. I jumped and she bit my mouth, telling me to be quiet. Until all of a sudden something that at first I couldn't identify entered into my mouth. She said: "Now, slave boy, you will have to suck on my feet"... I obeyed; it was the most humiliating order I had ever received, but I licked her feet without knowing what would happen to me if I refused to do so. Still not believing in myself when I felt her hands behind me suffocating me. I was running out of breath and begging her to let me go: "Please, Madam Carla, please"... She seemed not to listen to me and just kept repeating:"You haven't convinced me yet. Slave, plead with me, ask for more fear!!!" I couldn't get away from myself and was losing my senses when I started crying and asking him to stop that I could no longer hold it. Then she released me and I came back to breathe almost lifelessly. Seeing myself weeping, gave a laugh and another slap while saying: "You miscreant! Who made you cry?" I replied, "Excuse me ma'am". That appointment was a bit long and my mother did not even suspect that I had been subjected to various sadomasochistic experiments. It just happened on this one day. She said I should tell no-one unless they were going to make me contaminate myself when I went for the blood test. Innocent and trustingly, I promised to keep quiet. And then she said she would pick me up at home some weekend so I could spend a few hours in her castle. At first I was a little scared when she grabbed my dick again and said, "Then we'll be able to play with your pee-pee some more"... So after getting dressed and washing up, me and Mom promised that we would come back for the tests. And it was true. Yes, I did, but sooner than Mother had imagined. It wasn't until I went into the doctor's office where I found out that what happened in her consultation room is just what she calls an 'ordinary appointment.'
