Football And Tickling

When I was about 10 or 11 my buddy the same age used to come round to my place to play football on the lawn. We used to play a bit of football but with it being a contact sport we usually ended up play fighting and wrestling on the grass.
We would often tickle each other as well, under the arms and on our sides. This always used to make us squirm and laugh. Then one time when we were tickling each other I started to tickle him between the legs and he laughed like crazy and started writhing around on the grass, he seemed to really like it so I did it some more as we were rolling around. It felt nice tickling his privates then my little cock went really hard and as I was tickling him I shot a big load in my underwear. Then he started tickling me in the privates and I could feel his hand tickling and rubbing my little cock through my shorts, my cock was still hard and I shot another load. Afterwards I looked down at my underwear and it was soaking with cum. We started doing this regularly.
