(b) the following paragraph is inserted:

"My mother brought Preta from Veracruz, a small town near Marilia to work in our house. She was sixteen years old, five feet tall with brown eyes and black hair; her skin was fair despite the nickname she had gotten. Her appearance closely resembled Cabocla's character played by Gloria Pires on television. At that time I did not leave my home because I studied hard for dental entrance examinations at Fuvest and of course between one problem and another I would glance out into the kitchen where we could observe the sweet dancing of Preta's bum-bum. In fact, she was a serious sort of quiet girl in the manner of those simple girls from inside. She didn't look at me and I thought that she ignored me. Our relationship took some time to develop but once it had begun he walked with broad strides; our first contact happened on a beautiful day when I was having coffee by the cup: sitting at the table pretending to read newspaper, I pulled my Preta out from behind me leaning over the sink. Her hips were perfectly highlighted by her ex-employee uniform which was smaller than hers and fit just right. I got up and went to the sink on a pretense of washing my dishes. She said it wasn't necessary but I insisted. While I was doing laundry and she cut some vegetables, I stood by her side and ended up putting my right thigh against her left thigh. She didn't draw any reaction at all but suddenly slashed her finger with the knife and broke off the charm. Our second encounter was more meaningful. I was getting ready to go out and was shaving in the bathroom completely naked. Still foamy-faced, I heard a little noise behind me in the room. I turned around and found Preta standing next to the coma with a sheet in her hand staring at me. We didn't say anything, we just stood there, she was in the room, I was in a bathroom looking at us. That's when my penis started stiffening up. She kept watching it without showing any amazement. At some point I recognized an edge of curiosity in her eyes. Shortly afterwards she apologized and left. I continued shaving myself. The third date was divided into three stages. I had just come from cursive very happy because I realized that I was prepared for tests having done really well on the last simulation. I went up the ladder that washed rooms, and on reaching the corridor met Preta who was coming in the opposite direction with a pile of clean clothes in her arms. She gave me no other: I held her by the shoulders and pushed her against the wall while kissing her mouth. She did not resist and tried to retaliate even though she had very little experience and almost pulled my tongue out with her teeth. But someone called for her downstairs so we were separated. That afternoon, after my bath I walked through the window of a room and could see Preta in the maid's toilet because that idiot bricklayer who built our house had put his glass upside down. I started masturbating on the windowsill more to provoke her than for the scene. As she didn't understand me, I whistled. She was passive again; he just watched with interest as always. When I finished, she got up, smiled lightly and left. Towards the end of the evening I made it up to wash the motorcycle in the garage, only knowing that Preta would be there arranging the tool cabinets. When I arrived, she was crouched down sweeping the shelves. She saw me and asked calmly if it had been a good thing that I'd done at the window earlier. I replied that I would have liked it better to be with her. Then the girl revealed herself and proposed an agreement: I would teach her how to kiss while Ala masturbated myself. Oh my God! I pulled down my trousers and she grabbed firmly on my member as I dragged her toward me and kissed her. It was crazy; I stuck my tongue into the roof of my lover's mouth as she jerked my member up and down in frantic rhythm. When I made fun of her, she showed great curiosity about my sperm and noticed that it wasn't like this. Afterwards she started to greet me every time we crossed paths at home. The big achievement came on the last weekend before entrance hall. My parents went to Aguas de San Pedro and I decided to stay for studying. Since they are not fools or anything else, they tried to send Preta away before leaving. It was a Friday night when you were alone in your house. Suddenly the doorbell rang. She was Black. That fool had confused the departure time from his bus and lost his ticket. I invited her in, for I imagined that she had nowhere to sleep that night while my mind began to devise diabolical plans; it was now or never! Taking advantage of the absence of my parents and Preta's deception, I would consummate an act which he had been rehearsing since the beginning of the month. She sat down on the living room couch barely disguising a malicious smile at the corner of his lips. I could have sworn the deceit was intentional. I offered him a dose of whiskey as he prepared another one for me. Turning around, I caught a glimpse of the colour of her panties. The damned woman was wearing an incredible miniskirt, a courtesan's dress that showed off her phenomenal thighs. My member immediately hardened. I sat down next to her and we started kissing each other. She made remarkable progress in the art I had taught her and occasionally tried to outdo my master. But his master had more pretentious plans for this evening. Quietly unbuttoning Preta's blouse I inserted my hand between her breasts as I ran my fingers over those stiff little boobies which I had been coveting so long. Soon afterwards I began to suck them while extracting groanings from my young lover's testicles. She, not fooling herself, opened the zipper of my heel and freed my member who pulsed with excitement. Dai started masturbating him with her hands. Suddenly I stood up and put my member at his face height. She understood my intention immediately and started sucking and licking that huge head. It was my turn to moan for joy. She turned lessons in conventional kisses into a delightful symphony for mouth and tongue. When I sensed that she was about to make a joke, I stepped back and prevented her impetus from precipitating events. At this point I invited her upstairs into one of the bedrooms which she agreed with only an objection that since we were going up it should be in my parents' room on their double bed. On arriving at LA, I proceeded to undress her trying to get rid of her skirt and panties as well as stripping myself completely naked looking at each other. It fell upon her to take the initiative. She approached and touched my member with the backs of her hands while kissing me on the mouth and neck, dragging her tongue in a mad fury all over my body. I reacted immediately by forcing her to lie down so that she could work better her body with my dry language. I kissed her lips, neck, nipple from breasts as I walked across her jambon-colored back and stood upon navel. She moaned and spoke disconnected phrases, broken words without meaning. Black was completely taken up with desire and no longer looked like the timid little girl inside. Now she was a ferocious cat, thirsty for sex and pleasure. She was so upset that when I touched her clitoris with the tip of my tongue, it exploded into an animal scream while playing wildly in my mouth. Seizing this opportunity, I began to rub my phallus head against the entrance of its zero-kilometer trough, eliciting new shouts from my sweet little servant girl. She called out my name, moaned, cursed as she pleaded: "Get inside! Get inside me... In view of this, I began to force my member into her burning flesh, anxious not to be too rude or cause Her much pain. I felt a ring wrapping around the tip of my phallus when it was already on its way. By delicate movements, slowly forcing myself, I could overcome that barrier. When I found myself entirely within it and started moving my hips. She, who had been somewhat frightened by the initial pain, voiced groanings again and in no time we were climbing as if we'd never done anything else in life. It was becoming something out of this world, because Preta was completely possessed and her cramped cave led me to an unparalleled orgasm that kept me off the air for a long time. That night as well as all other weekends we started perfecting our techniques. I passed through the lobby despite everything but never missed any opportunity to be alone with her until last year when she left home after a quarrel with my mother.
