With a mischievous grin, the boy slips off his briefs, revealing his throbbing cock. He runs his hand up and down the length, feeling the heat and friction build. His other hand reaches down to cup his heavy balls, rolling them gently in his palm. The bathroom fills with the sounds of his wet, rhythmic strokes and the occasional soft moan, as he brings himself closer to the edge, chasing the sweet release he craves.
