Very similar to my experiences, went to my church camping holidays! Was ages between 14-18 though! The guy in charge encouraged it! Although he never got fully involved he would watch & instruct, he would be stroking his cock. I was 15 when I first went first evening I had 2 18 yo lads in front of me & I was sucking them going from one to the other, one was mixed race, his cock must have been at 8 inches found it hard to swallow it all, the other lad was white average cock but quite thick! When the mixed race lad cum it was a heavy load I had his cock throbbing in my mouth for a while until he pulled out I swallowed quite a bit the rest just seeped out my mouth! The other lad cum over my face his was a pretty big load too! I noticed that the guy in charge had blown his load too as he watched.
