SEA for three days insuccession

I went back Nagasaki as my hometown from August 12th.I was very excited. I have gone the sea with my friends to swim for three days in succession. The sea we went is near my hometown.We went to the sea by my friend' s car. When I arrived at the sea, I thought that after all the sea is good. We swam for a long time as children. But, we sunburned. After we swam, we did a barbecue. It was very exellent.
