First sex with another man

It happened a long time ago . I was a young adult student . The partner and I had the same age . He has noticed the size of my cock when we were both changing for sports and he was amazed by it . He managed to bring me apart pretending he wanted us to talk about sex in general . As a young man my hormones were at such a level just to think of sex aroused me . We met a few times and at the beginning we just drop our pants and masturbated . He dared to touch my cock telling me he wanted to know how it felt to have a bigger cock in his hand . His was small but when it was erected it was hard as a steel bar . Our meetings used to end when we both had come . One day I brought the subject of fellatio telling how much it should be good to have a pair of lips around our cock . He agreed . I asked him if he would like me to suck his cock . He said he would be pleased but he told me that he was concerned about the fact that he would come in my mouth . I told him that I didn't mind . I kneeled down in front of me, he took his cock out and I started to suck it . I was so clumsy . I didn't use my tongue and my lips, I was just sucking . So he started to fuck my mouth . He warned me again about the fact that he would come in my mouth and told me he would squeeze my shoulder with his hand when the eruption was coming . He fucked my mouth and after a few minutes I felt his hand on my shoulder and second later I tasted his cum . I spit it out because I didn't know what to do with it . I wasn't not disgusted . I asked him if he enjoyed it and he said yes but he added that my teeth hurt him a bit . It was not a great performance . Today I know a lot more about blow job . My ex fiance was an expert and she made me scream every time she sucked my cock . Now I dream to do a good blow job to a man , using my lips to rub and kiss his cock, licking it with my tongue, gently bite it and finally take his cum in my mouth and swallow every drops . Any volunteer out there ?
