My grandson, how it all began.

For some reason, I lost all my stories. I was able to retrieve this one because I had posted it on another site. I'm only posting because some of the regulars here on the site are always asking me how I got into anal sex with my grandson. Sorry if you've read this. My name is Joana Maria, I live in Sorocaba, I'm a seamstress, I'm 64 years old, I've been a widow for 16 years. I'm 1.65 meters tall, I weigh between 72 and 74 kilos. My breasts are medium to large, not yet so droopy. What bothers me the most are my buttocks. At school, my friends called me tanajura. Thin waist and buttocks very protruding. Today, I already have a small belly. I got married at 32 years old, still a virgin. My late husband was 45 years old when he died, my lunch, I had just gotten a baby who I always treated like my grandson. When Silvana wanted to go to the cinema, or a restaurant, or a show, she always left the boy with me. And so I accompanied his growth. Since he was a boy until the age of 14, he didn't need to go out on Sundays anymore, so when she passed, I went to her house. Silvana is a physiotherapist, and with this blessed pandemic her life, like everyone else's, has changed. Her working hours have changed and schools have started to give remote classes. Depending on the schedules, he asked if I could be with my grandson every Tuesday and Thursday from 09:00 to 17:30. That was in January of this year (2021). I've arranged the guest room, which I've hardly ever used, for him to be comfortable and have some privacy, and on Tuesday, as soon as he arrived, we went to arrange a desk and an extension which I didn't even know was called a ruler. He set up the room the way he wanted it and we agreed not to disturb each other, that is, I wouldn't be asking him if he wanted anything, juice, snacks, and he wouldn't come to the atelier when I was serving some customer. Renato, as this girl speaks, turned out to be quite a CDF. He wanted to do computer engineering. And so were our days. He came, went to the room, we had lunch, talked a little and each went back to his routine. As usual, on Tuesday, shortly before nine o'clock, Silvana left Renato and went to work. That day I had decided to clean up in my studio. I rarely wear bermuda, or long pants, I prefer to wear dresses, so disguise my butt a little. That day, I casually put on a bermuda, cotton, a T-shirt and started to clean up in the studio. I noticed that Renato was a little strange, seemed to be anxious. He went to the room, stayed for a while, went to the kitchen, went back to the room, came to ask me if he needed help. I found that he was quite restless. I finished packing things, took a bath and went to make lunch. During lunch, Renato continued to be restless. After lunch, Renato turned on the TV channel and stayed to change the bathroom, and after a while he went to the bathroom, and there was no problem. In the middle of the afternoon, after having served two customers, I went to pee and realized that my bermuda was in a different way than I had left it, by the way, I had left it in the basket under my shirt and it was on top of all the clothes. Since no one but me and him had used the bathroom, only he could have moved the basket. It did not take long and Renato appeared in the studio. I asked if he was okay. Renato said that he had seen something and that he was not able to concentrate on the classes. I said that I could be a little mentally tired, stay at home, lady, without contact with friends, stay all the time in front of the computer screen, I could really have given a little of this joke. He looked at me and said: Dinda, after my grandfather died, did he like my body? No one else? I replied that I was not used to having sex, I wanted to kiss him, I wanted to be alone, he could have moved the basket. It did not take long and Renato appeared in the studio. I asked if he was okay. Renato said that he had seen something and was unable to concentrate on the lessons. I said that I could have really given him a little of this joke. He looked at me and said: Dinda, lady, after my grandfather died, did he never had a good body? I was confused, I didn't know what to say. I asked if he was too young to know how to satisfy a woman. I asked if he had ever had sex with anyone. He said yes, that he had learned how to satisfy a woman. I asked him where he had learned to have sex. He said that he had learned from a lady, about my age and who was an acquaintance of my stepdaughter. I asked who this lady was, how he had met her. Renato replied that her name was a secret. He said that one day he was coming home from school and this lady, who lives near the school, called him, invited him in and asked if he had ever had sex with any girl from the school. He said no. Then she asked him if he would like to have sex with Que, she would be happy to take his virginity. I was freaked out. Renato continued talking: - "She asked me if I could cancel the physical education class next Monday. That if I wanted she would give me some lessons on how to touch and penetrate a woman. I accepted. And so it was. One Monday I was going to do physical education and the other I was going to my classes". She gave a very naughty laugh. He said that my stepdaughter had met her at the fair and commented that she had a certain fear that he was gay. She would accept, but said that my father would be very disappointed. - Renato, I said, let me say two things. First, never stop using a condom, it wouldn't be any good for you to get a woman pregnant. Second, don't forget that I'm your Dinda, your grandmother. So even if you say and give all the hints that you want to have sex with me, we can't. He, always assertive, always straight to the point spoke to me: - "Dinda, first, the way I learned, it's impossible to get a woman pregnant, secondly, the truth is, you're not my grandmother". I asked how it would be this way of having sex without getting pregnant, if he, at the time of ejaculating, he took it out. Renato said no. That he ejaculated inside. But it was impossible to get a woman pregnant. Still not understanding, I asked if he could explain it to me better. He said: "Dinda, the lady has already been married, you know well that sex behind does not get anyone pregnant". I was speechless. This woman had turned my grandson into a pervert, where has it ever been seen to teach the boy to have sex behind? I said that his grandfather and I thought that sex this way was sinful, dirty, something that a woman goes out with anyone for money. I don't know how you and this lady like it and are satisfied with this way. I can't imagine, I'm sick just thinking about it. "Dinda", he said, "but there's nothing dirty. It's just that the woman prepares herself before there's any dirt. I was annoyed, disgusted, I didn't even want him to sit on my chairs, on the couch. I asked what that preparation would be like. So he explained to me that before having sex from behind, the woman has to do an intimate hygiene. Which was just to take the shower, put a little shampoo or butter on the end of the hose and put a little inside the butt. Let some water in, hold and release everything at once in the toilet. It was to do this three or four times that the water would come out clean. That the anus would be clean, ready to be licked and penetrated. I didn't know what else to say. I was totally disgusted. I went to the kitchen and took a glass of water and said I was going to lie down for a little bit. This conversation had made me sick. I asked him if anyone came, he would come to my room and call me. I lay down and my mind was just thinking who this lady could be? How crazy is it that she teaches him to start his sex life in this most stupid way. What an idea to stick the hose in the anus as if doing a stomach wash. On Thursday he came, we had coffee and we didn't talk much at all, and that went on for two weeks, but all I had to do was look at him and it all came back into my head. I take my early walks. I arrive, I take a shower and go to the workshop. It was Tuesday, I took the walk and I went to take my shower. I was in the shower, soaping myself, and when I started washing my buttocks, the story of sex without getting pregnant came to my mind. Without realizing it, I was soaping my anus longer than usual. I thought I was going crazy, but it made me want to do this kind of intimate hygiene. I put the washing machine on and let some warm water in. I got a rush, I immediately wanted to let go. I went to the bathroom and I took a quick breath. I stood up and I thought I was going crazy, and I went to the bathroom and I really cleaned up, and I went out for the third time in my life. Renato arrived, we had coffee, we didn't talk much. Lunch time arrived, we had lunch and Renato soon went to the room. While I was washing the dishes, the little seed of evil began to want to germinate. I had customers to attend. Around 16:00 I was already free. I went to pee and again I saw that he had touched my panties. I took a deep breath, came out of the bathroom, and went to make a juice. I called him to drink. I stood in the sink, back to the door and when he arrived, I grabbed the bar of my dress and began to get up. Wasn't that what he wanted? Soon! He was there I was showing my buttocks to him. - You didn't want to see and caress? He came from behind and he started to suck my hands in my thighs and my nails. But he was going to suck my hands in my eyes and my nails. He grabbed my buttocks and went to the side of my calf and kissed my calf. He was already pulling my calf and began to push me back. Renato waited a little and said: "Now it's my turn". He asked me to bend down on the bench, lowered my panties, put his penis between my buttocks and began to rub. He tightened the bands of my buttocks so that his penis was all embraced. He passed the penis on my chest and rubbed it again in the middle of my butt. I noticed that his breathing began to be altered, I knew what was going to happen. Then he leaned the head of the penis on my anus and made a slight pressure. The lady thought he was going to try to penetrate me, but not. He ejaculated on my anus and then began to pass the penis through my buttocks, leaving me completely naked. He lowered my panties, and he went to the bathroom. He turned to my calf. I kissed him on the butt and gently rubbed it in the middle of my butt. I noticed that his breathing began to be altered, I knew what was going to happen. Then he leaned the head of the penis on my anus and made a slight pressure. The lady thought he was going to penetrate me, but he did not. He ejaculated on my anus and then began to pass the penis through my buttocks, leaving me completely naked. He lowered my panties, and went to the laundry. He turned to the laundry. I kissed my calves. I kissed my calf gently. I asked him on my calf so I kissed him and put it in the middle of my butt, and he was going to take off my butt, and I was going to cleaned it. He went to my vagina.
