First and second time all in the same day.

I have gone to Adult Bookstores before to get my cock sucked but today I wanted to see what it would be like to suck one myself. I had the day off so I went across town to the local bookstore to see if I could see what it was like to take a cock in my mouth. When I got there I went into the back booths looked for ones with glory holes. I sat down in the booth and watched some videos of guys sucking cock waiting for someone to show up. I waited about a half hour and no one showed so I was going to leave. When I went back into the store the clerk said it’s real slow today. Then he asked me if I was looking to suck or be sucked and I said I have never sucked a man but wanted to try today but just my luck no one was there. He said he could not go in back with me but if I wanted to I come behind the counter and suck his. My heat started to pound and said to him what if someone comes in? He said they will never know what was going on because the counter was high and would block anyone from seeing. So I went behind the counter and kneeled down in front of him then he took his cock out it was very thick but only about 5” long but looked nice. I started touching it then started licking the head till I was so horny that I took it in my mouth. I was amazed that I could take it all the way in my mouth. Then I heard the chime of the door ring and stopped sucking and he said keep going he will never know so I did. I have to admit it made it even hotter knowing that someone was there in the store while I was sucking his cock. I felt him tense and I was not sure I wanted him to cum in my mouth but I just could not stop. I felt his cock pulsing while he filled my mouth with cum I kept sucking him with his cum still in my mouth I did not want it to end but he took his cock out of my mouth and said I did great for my first time. I told him how much I enjoyed it and I think I am hooked and want to do it again. He said the guy that came into the store and went into the arcade had a nice cock and if I wanted to he is sure he would let me suck it. I went into the back and went into the booth next to him. The clerk was right, he had a big thick cock and he saw me looking through the hole. The next thing I know his cock was coming through the hole. I sucked him for about 15 minutes till I head him say he was going to cum and then I felt his his cock twitch and fill my mouth. When he came my cock that was out of my pants started coming too and I blew the biggest load I ever had all over the booth. His cum was thicker than the clerks and more of it than his. He then thanked me and zipped up and left. When I went out into the store the clerk said wasn’t I right his cock was very nice. I said yes you were and I enjoyed my second cock as much as the first. When I left and went to my car the guy in the booth was still there and said I was a good cock sucker and if I wanted to do it again let him know and he gave me his number that I called a couple of days later but that is another story.
