I loved doing these things when I was young. These bring back memories.
When I was very young, probably around 7 or 8 my male friend and I would play with each other. We use to masterbate together every chance we could when we were alone. Then one day around age 12 or 13 I started cumming when I orgasmed. At first it was very weird but I began to enjoy shooting my cum when I came. I started growing a lot bigger too and really loved the feel of my large tool in my hand. Now that I am older of course I still do this but I do enjoy those early naive years.
