We play some beach volleyball.

"C'mon, let's get this started already!" Samantha says, stretching her body. "Becky, where's that volleyball? I wanna get the blood pumping."

""Looks like John is already one step ahead of us," Becky sniggers, still eyeing my erect cock. Samantha gives her a teasing smack to her butt.

The four of us form a misshapen square around our own patch of the beach and start to pass the ball around. It takes a while to get the momentum going, but it's not long before we're running and diving into the sand, making **** plays for a stray ball. Within minutes we've gotten sand all over ourselves and have a good sweat going on.

"Oh god it's so hot," Susan gasps, wiping her chin.

"Yeah," Samantha nods, wiping her brow. "But it feels good!" I nod in agreement. All the exercise had **** my blood out of my penis and back into my body, but it was still awkward to run around with my junk swinging left and right.

After a bit more volleyball, we decide to jump into the sea to wash off our sandy bodies. As I stand waist-deep in the water, I can't help but notice the glistening bodies of my friends as they got their bodies wet. Whether it was the sweat or the seawater, I don't know. But watching them rub off the sand from their bodies quickly gives me a hard-on.

"John, you okay?" Samantha asks, noticing me staring. I snap myself back to attention and quickly nod. "Yeah, it's nothing," I say.
