When my grandfather moved in with us, everybody had a job except for me and wasnt working. So I had to watch him from 8am till noon when my mother got home. He was kind of senile, and didn’t really know what was going on around him, because his age was 97 years old.At fifteen years old , I was very curious about being with other guys. One day I went into his room and told him that they doctor wanted me to take his temperature . I told him to sit down in his chair and I would take his temperature . He sat down and I undid his pants and pulled them down and then I did the same with his underwear. I took his c*** and started sucking on him. At first he didn’t like it but I told him this what the doctor told me to do. So I started sucking him till he came in my mouth. I told him thank you grandpa and then he pulled his underwear up and then his pants. Later the morning I walk in his room again and told him that I needed to take his temperature again. So he sat down in his chair and I took off his pants and underwear and I took off my pants and underwear and I started sucking him and was jacking off at the same time. He came again in my mouth and I swallowed all of his c**. Then I got off all over myself. I got up and told him to put his underwear back on and his pants. About 30mins and my mother came home. I did this everyday for a month and then one day my dad came home early and caught me sucking him off. I was naked down in front of him and he was c****** in my mouth right when my dad walked in. I had most of his c** in my mouth but not all of it. My dad tells my to get up and go to my room and he would be there in a min. My dad walks in my room and shuts the door and locks it and he asked me how long have I been doing this with grandpa. I told him from the second or third day he was here. My dad tells me that I need to take my clothes off and lay down in my bed . My dad takes all his clothes off and opens up my legs and then starts sucking me. I started to c** and my dad sucked it all out of me. Then my dad put his c*** up to my hole and pushed his way inside me. He fucked me for about 10 mins and came inside me. We did this about 30 or 40 times after that. Some times dad would make me s*** him off. I never didn’t say no.
