First Time With Cocks

Many years ago, I was 13 and at an all girls school. Other girls in my group were talking about giving their boyfriends 'wanks' to make them shoot off. I had heard about it of course but didn't really believe them nor did I have a boyfriend and in any case would have been to timid to try it. A few days later, one evening, my older brother, 15, and his friend were at the house when parents were out. I caught them looking at porn mag (remember them?) and I jokingly said that I would tell mum. Brother asked me not to and asked what I wanted, expecting me to say money or do jobs etc but I suddenly said that I wanted to see their cocks. They said no but eventually agreed and dropped their shorts. Brother's cock was not hard but his friends was but within minutes he had also stiffened. I swear my eyes were popping out and I reached out to take one in each hand. It was a strange thing, not something that I would ever think of doing. I asked them if it was OK and started rubbing. Of course within minutes both had cum. I recall the friend's spunk shot out while brother's was less of a spurt but it was thicker. We hurriedly cleaned up worried that mum or dad would come back. Did we do it again? Yes and more but never actual sex.
