My first deer, we (my Dad, uncle, and brother) had been hunting all day, and were heading back home. We pulled off into a pull-off, I think Dad had to take a piss or something, and there, standing in a gap between the evergreens, was a deer! My brother helped me get set up with the .303 British, I was 14 years old, he was 16. And then I shot it! it was a fawn!! I thought it was a doe, but oh well, meat is meat.
The better story is my first hunt with my son. My brother and I had put in for a group hunt (with our two sons) for caribou in the Atlin area, and we got 4 tags! So we went there and hunted hard, and finally connected with a caribou for my son, it was an awesome hunt, we had glassed the herd of caribou from the truck, then driven to where they could be accessed, then hiked up to the ridge and started hunting along the ridge in the direction they were heading. We waited in a gully where they should have appeared, then decided that they had stalled out somewhere along the ridge. So we continued along the ridge, and found them, the whole herd (probably about 40 cows and calves)! We crawled up towards them on our bellies, then finally saw the bull, who had laid down in a gully. So we crawled a bit further, then my brother said, OK, let's shoot him, and my son, a 14 years old, laid the gun (a .25-06 Browning Left Hand bolt) over my brother's back, and squeezed off. Immediately, he rolled onto his back, and was holding his ears! I was absolutely alarmed, and said, "what happened? What's wrong?" It turned out, that was the first time he had ever fired a rifle without hearing protection! I had always, of course, supplied him with the appropriate ear-muffs when we shot at the range, and he was a really good shot!
So we went up to the bull caribou and had to put a coup de grace into it, but still, my son was 13 years old, and so that is my story for this time.
