15 at the time
I was heading home with my parents from summer vacation in Australia and I knew that the journey was going to be a very long one. Before we boarded out flight I decided it would probably be best to jack off since I had not done it in a few days. I ditched my parents saying that I needed the bathroom before running off to actually find one. Though we were already at the gate, the line for the bathroom was packed with passengers waiting. I wasn't in any patience to wait so I decided to duck into the baby changing room.
Once inside I locked the door and instanly took my pants off. My raging boner was already up by that time and I quickly went at it.
It was not long before I started to feel the good feeling through my legs and I knew I was close to cumming. I realised that I didn't have any tissue and there was no sink in the baby changing room. I looked around and then noticed a used diaper hanging on the top of the bed. In the spur of the moment, I grabbed it, pointed my hard cock into it and shot five huge loads into it. It felt so good since I had not done it in a long time.
Once done, I wiped my hands on the outside of the diaper and then threw it back into the bin, got dressed and left heading back to find my parents.
