We parked, and the girls hurried down to the water, flip-flops flipping and flopping on their feet. I carried our cooler down to a picnic table where the girls had laid out their towels. I slipped my towel from my crotch, glad that my erection was gone. My mom, who wasn't swimming, settled in at the picnic table with a book that she had been reading.

I walked down and put a toe in the water, and I found out why the girls were squealing: it was freezing cold. Damn, that's going to hurt going around my full ball sack. I started slowly into the water, but submerging myself inch by inch was torture. The girls paused in their frolicking to watch my discomfort. Fuck it. As soon as the water was deep enough, I dove in.
