I was walking home across a large playing field/park near my school in the UK one morning and I saw in the distance someone on their knees.
I decided to walk over that way to have a closer look, as I approached I could see that there were others and as I got closer could see that there were three boys, two were lying on the grass face down and a bigger boy kneeling between there legs with a hand up each of the boys baggy shorts.
Wow I thought!! and as I got close could see that the older boy was from my class at school. He was so engrossed in feeling the boys bums that he did not hear me approach.
So I just said can I join you Brian that looks like fun. They all spun round to look at me.
Brian said they were his twin cousins aged 15.
I told the twins to lie on there backs and I got down and put my hands up there baggy shorts leg and had a good feel of their balls and dicks, they giggled with pleasure.
I said to Brian should we show them how to wank, Yep they all said, so we went to a more secluded area and I said we should all take off our shorts and underwear, so off they came all out dicks were uncut Brian's about five inches with some dark hair over his dick mine was the same size only brown hair, the twins were hairy about five and a half inches all of us were rock hard. I first had a feel of Brian's dick and wanked it a few times, he did the same to me. Then we both grabbed hold of the twins dicks and wanked them a few times, we were all excited so we got the twins to wank our dicks so they could feel what to do up and down and we said to go a bit faster, then we laid back with them both wanking us hard and fast until we shuddered and our cum shot all over there hands, they looked at the ropes of cum and I told them to smell it and they did before cleaning off on there underwear.
We then told them to lay back and we wanked their dicks fast until they both shuddered and had a dry cum. They said it was the best thing ever.
