Bored and horny, a solo boy decides to make the most of his time in the sun. He stretches out on a towel, his hand wandering down to his crotch. He rubs his semi-erect cock, feeling it grow harder as he thinks about the taboo thrill of masturbating out in the open. He pushes his shorts down, revealing his stiff, engorged cock, and begins to stroke it vigorously, his balls tightening as he nears his climax.
