This happen to me when I was younger for awhile my best friend and I had been playing with each others cocks and rubbing them on each others arses. The more we did this the more curious I became what it would feel like to have his cock in my mouth. So one night as we were lying on the bed playing with each other I rolled on top of him and kissed him deeply, then slowly worked my way down his body kissing his nipples and stomach and finally got to his now very hard cock. I started to stroke it gently and started to kiss his balls. By this point he was gagging for me to put his cock in my mouth which of course I did. I have never known a nicer feeling that felt totaly natural. I start to kiss the end of his penis. The start slowly to move further and further down his cock until I had it all in my mouth I could not get enough. After a couple of minutes with me lying on top of him sucking his cock, he made me get on my knees while he stood. He looked down at me, bent down kissed me again and ask if he could come in my mouth I was unsure at first but as I continued to suck his cock I got lost in the moment and when he came the feeling was nothing I had experienced before and it tasted really nice, I swallowed the lot and cleaned his cock afterwards. He then lay me on the bed and made sure the favour was return although he would not me come in his mouth but that did matter I achieve what I wanted that night. We carried on for awhile afterward until I moved away from the area and have nothing since, but am now looking to try more.
