The bathroom fills with the sound of the pounding water and the boy's heavy breaths. His cock stands at attention, ready for his expert touch. He spits into his hand, using it to slick up his shaft, his tight grip sending shivers down his spine. His other hand cups his balls, rolling them gently as he picks up the pace. The sight of his body, slick with water and sweat, is enough to push him over the edge. He bites his lip to stifle a moan as he comes, his cum mixing with the water at his feet.
