First time being seduced by an old man

When I was 13, I got a job cleaning the office of an older man. He was in his 70's and married with a successful business and he was very nice to me. I cleaned his office 3 times per week and after the second week, he stayed in the office and asked me to sit by him on the couch. I sat down and he moved close to me and put his hand on my knee as we talked. I was a little bit embarrassed but I didn't mind. He moved his hand up my leg until he was almost touching my crotch. Still embarrassed but feeling a little horny, I put my hand on his knee. He relaxed and softly rubbed my dick over my pants. He said "Will you pull your pants down?" I was shocked but curious. I said shyly, "It's small so you won't like it". He said "OK, I'll pull my pants down first if that's ok". I said it was ok, so he stood up and dropped his pants. I could see his little penis and balls through his underwear and he looked quite small. He said "Do you want to see it?". I didn't respond because of embarrassment. He pulled his underwear down right in front of me as I was still sitting. He moved closer to me with his little dick hanging close to my face. He said "You can touch me" so I shyly put my hand on his tiny penis. He let out a moan when I gripped his dick. He said "Put it in your mouth". I said no. He said "At least pull your pants down and let me see yours". He sat down, pulling on his dick. I stood up and pulled my pants and underwear down. There I was, standing in front of an old man who was rubbing his balls and looking at my cock. He reached out with both hands on my bare ass and pulled me close to him. He licked my cock and it felt so good! He continued rubbing and squeezing my ass when he put my cock in his mouth, I was so excited! He touched my balls, my cock, put his finger on my asshole. I didn't cum, but got close. He then told me to sit down by him again. He told me to lean over and touch his big, smooth balls. I put my hand on his balls that were bigger than mine. I liked the feel of them and played with them for a minute. His dick was much smaller than mine and not fully hard, just semi-hard and about 3" long. I wasn't so shy anymore, so I licked his little dick. He said "Keep going, lick my balls". I did and then put my his little dick in my mouth. He jerked and moaned when I sucked his little weenie and let him cum in my mouth. I liked it a lot! I continued cleaning his office for a few more months. In that time, he didn't suck me but he wanted me to go down on him often. I didn't mind and still don't. Because of him, I've had a fetish for sucking small old dicks ever since!
