Roger and Andy did this on purpose.
When I was 16 I went to the community swimming pool as there wasn't much else to do. I was home from school for the Summer. When I got there I was alone. I quickly took a swim and then got out of the pool. I then noticed that these two boys, Roger and Andy, had showed up. They both were laying face up on a couple of lounge chairs taking in the sun. We said hello to each other and then I went about my business at the end of the pool in the shade.
I then headed to the other end of the pool to get a soft drink. As I walked by the boys I couldn't help but notice their swim suits. I was in a bikini and they had been laying there looking at me. Both boys were obviously getting erections. I got my drink and walked back. By now there was no doubt as both were really showing. One had on a tight fitting suit and the other the loose fitting swim trunks and in this one it was like a tent pole. As I walked by both boys were looking stright at my eyes wanting to see me looking at them and their crotches. This was all on purpose and I knew it. They were putting on a show for me.
I went to my end and I couldn't help myself and wanted another close look so I made another trip past them and this time I made sure they saw me looking at there 'show pieces'. On my way back one of them then asked 'are you enjoying the show'? I stopped and answered back 'I sure am'. Then Roger asked 'would you like to see more'? I answered back 'what do you mean'? He then asked 'have you ever seen a boy jerk off before'? Hearing this made me blush a little. I answered back 'no, I haven't'. Roger then asked 'you want to watch us do it'? I asked 'where'? He then said 'lets all go to the family dressing room'. They got up and we headed to the dressing rooms. Both boys were rubbing on there erections as we went there.
We got there and went into one of the booths, went in and locked the door behind us. I sat on the bench and they turned facing me and Roger then asked 'are you ready'? I said 'yes'. They looked at each other and then both pulled down there suits. There before me for the first time were grown boys with there erect penises out. I couldn't take my eyes off of them and had wanted to see one for a long time. They then wrapped there hand around themselves and went to jerking off right in front of me.
Roger then said 'you're going to get to see us come off in a minute'. I'd always wondered what this would be like and I was about to find out. Roger went off first squirting his cum on the bench right beside me. I was fascinated watching this. Roger was down to just oozing his cum when Andy started with a loud grunting sound and he shot his off. His went further than Roger and the first squirt landed on my leg. The next landed on the bench and then the floor. I felt the cum with my finger wanting to see what it felt like.
They then put their suits back up and we went back out to the pool. Both boys commented to me how good I look in my bikini and I got them like this to begin with and both thanked me for letting them jerk off in front of me. I've since learned that this is a real thrill to a boy and have since witnessed this hundreds of times. It is something I never got tired of seeing.
