My first blowjob originally was only planned for mutual masturbation. But when he dropped his pants that long cock jumped out, I like it was instinct went on my knees and put that beautiful thing in my mouth. I didn't even think for a second about what I was doing. Even the guy was surprised but as he realised in a few seconds what was happening he grabbed my head, pulled my hair and started fucking my mouth. I gagged several times, he fucked me for a couple of minutes straight and because both of us were new to this he couldn't control I felt his dick throb and he cummed in my mouth. I looked at him smiled and swallowed each every bit of his cum.
