Many years ago when I was 19 I worked in a retail shop that sold timber and paint etc. My boss used to go home lunch times sometimes staying away for up to two hours before returning. This left me alone in charge. One day a elderly asain guy about 50 years old came into the shop and was asking about some samples he needed to look at to match some furniture at home. The samples were in a corner of the shop and as I was showing them to him I hadn't noticed that he held a carrier bag with some items in by his side whilst he was pointing to samples with his other hand. He was moving about a little and brushing into me with the hand holding the bag.I had nowhere to go as I was leaning back against some of the stock. His brushing was against my groin, unaware at first until I felt myself getting an erection.The guy noticed the bulge in my trousers and commented that my girlfriend must be a lucky girl to get to play with that, I didnt have a girlfriend and was still a virgin, I dont know why I answered him and told him that that too. He laughed and patted my groin making me gasp. There is a sign in the shop that says all customers looking at timber at the rear of the shop have to be accompanied by a member of staff in case of a accident. Maybe is was being young but I never cottoned onto it until later but he asked to see some timber, we went to the rear of the shop out of sight of the public at the front and as we got to the back he turned to me and leaned forward and started to kiss me. I just froze as he started to french kiss me pushing his tongue into my mouth and exploring ,I responed out of fear i think but also curious and we started to kiss passionately together. He pulled away and opend my trousers and slipped his hand down to embrace my erect cock in my trousers and began to rub it for me. I had my eyes cloed loving every moment. After a short while he opened his zip, pulled out what was an enormous cock, the first mans cock I had ever seen and told me to rub is for him showing me how to hold it . After a few minutes he pushed me in the stomach telling me to kneel down which i did. I was now face lever with this enormous brown asain cock. He told me to suck it. I had seen pictures on toilet walls of this so did as I was told. I now had the first ever cock in my mouth and was sucking it. This lasted for a few minutes until I felt him hold my head as he quickened his trusts in and out of my mouth, suddenly I felt him cum in my mouth several times until he stopped. I had never tasted cum before not even when I had wanked alone in my bedroom at home. He stood me up and began to kiss me again, I had no option but to swallow his cum to respond to his kissing me. It tasted salty but nice too.He finished kissing me , zippped himself up and left, every day for weeks he would wait up the road to see my boss drive home for dinner and then come into the shop and have me suck him off again and again. One day I wanted him to fuck me but he said he would but at his friends house, Alas I never went there afraied that I might be hurt by too many guys fucking and using me, In hindsight I wished I had gone..Some years later though I did get to be fucked by a guy whom I met in a chat room on line..
